Cognitive Psychology Overview

How does affect ? What types of information are more difficult to remember? What strategies are useful for storing and retrieving information? How can a teacher facilitate learning by better memory?

The purpose of this chapter is to help you learn about the Information Processing Model and other related cognitive concepts through encountering and resolving a classroom problem. The problem this story is based on was a regular concern with one of the authors' 3rd-grade classes, and one you're likely to encounter as a teacher.

Cognitive psychology (also known as ), a term used to describe "the process of ," is a branch of educational psychology that explores internal mental processes (Neisser, 1967). There are 6 different thought processes in cognitive psychology that have been researched extensively.

1. 2. 3. memory 4. 5. reasoning 6. decision making

PAMPRD is a to help you remember these 6 mental processes of . They combine to influence behavior and learning. These will be discussed in greater detail in this chapter.

Various models have been developed by cognitive theorists to describe how individuals think and process information. The most commonly accepted model of how the brain structures memory is referred to as the Information Processing Model (Atkinson & Shiffrin, 1968), which addresses perception, attention, and memory (PAM) in the six thought processes described above.

Cognitive theories propose that the mind has a general architecture for processing information, often comparing the way our minds process information to the workings of a computer. In other words, the human mind is a system that processes information through the application of logical rules and strategies. Also like the computer, the mind has a limited

capacity for the amount and nature of the information it can process. Just as the computer can be made into a better information processor by changes in its hardware (e.g., circuit boards and microchips) and its software (programming), learners can also become more sophisticated thinkers through changes in their brains and sensory systems (hardware) and in the rules and strategies (software) they learn.

Sensory Memory

How does attention affect memory?

The standard information processing model has 3 major components: (a) , (b) (i.e., short-term memory), and (c) long-term memory.

Sensory memory, the first level of memory, allows us to take a 'snapshot' of our environment and store this information for a short period. The environment makes available a variety of sources of information (light, sound, smell, heat, cold, etc.), but the brain only understands electrical energy. So, the body has special sensory receptor cells that transduce (i.e., change from one form of energy to another) this external energy to something the brain can understand. Through transduction, a memory is created. This memory is very short; less than 1/2 second for vision, about 3 seconds for , and about 10 seconds for touch (Gilson & Baddley, 1969; Mahrer & Miles, 2002) .

Can you imagine trying to process information about every single stimulus you experience? Your brain would quickly burn out! Fortunately, sensory memory acts as a buffer for stimuli received through the five . Perception is the process of recognizing different stimuli. A sensory memory exists for each sensory channel: for visual stimuli, for aural stimuli and for touch.

A stimulus must first be perceived. In order for the information to be further processed, attention is key.

Attention is a cognitive process that allows us to focus on particular environmental stimuli (Anderson, 2004). Once perceived, paying attention to something allows information to pass from sensory memory into working memory. Thus, attention serves as a filter for stimuli from our environment. By selectively determining what will 'get through' for further examination and what will not, attention allows us to focus on only the necessary stimuli.

example Think back to a time when you were in a crowded room and a lot of people were talking. Were you paying attention to what each person was saying? Probably not, but what happened when someone in the room said your name? I bet your ears perked up. Even though you may not have actively perceived the words of the many conversations around you, your brain did. Most of that information was quickly discarded because your brain quickly judged you didn't need it. The common pattern of hearing your name, though, triggered something your brain might have thought was important and caused you to pay attention (the conscious act of recognizing a perceived stimulus) so you could move that information to your working memory and decide what to do with it from there.

Cognitive psychologists have identified many different types of attention including:

Alternating attention: Mental flexibility, or the ability to move focus between tasks with different cognitive demands. Divided attention: The ability to respond simultaneously to multiple tasks. Focused attention: The ability to respond directly to touch, sound, or sight. Selective attention: Ability to maintain focus on a specific stimulus even with competing stimuli fighting for one's attention. Sustained attention: Vigilance, or the ability to remain consistent through continuous and repetitive activity.

So what?

How can knowing about sensory memory actually help you as a teacher, though? Whether they realize it or not, most effective teachers already use sensory memory to their advantage by creating some type of advance organizer. An advance organizer prepares students to pay attention to specific aspects of the lesson before they are even presented (hence, the term "advance"). A worksheet given before watching a movie, a of questions to guide students' thinking, or an activity that draws students' attention to a specific aspect of the lesson, are all ways in which you might have already experience an advance organizer. Teachers commonly refer to these as an "anticipatory set" or the "hook" for the lesson.

Working Memory

What happens after attention? How do learners work with new information? How can teachers design instruction to maximize learners' working memory capacity?

Working Memory

Whereas sensory memory is the initial door for recognizing the many stimuli that confront us, we have to actually do something with that information if we are to learn anything. Information that is attended to (i.e., that makes it past sensory memory) goes into a temporary store where we can actively work with it. Atkinson and Shiffrin originally called this Short-term memory. Short-term memory is the capacity for holding a small amount of information in the mind in an active, readily available state for a short period of time. The duration of short-term memory is believed to be a matter of 15-30 seconds.

In 1974, Baddeley and Hitch extended cognitive scientist's understanding of short-term memory by proposing that short-term memory is actually a sub-component of a system of working memory, which emphasizes functionality over simple . Storage, though important, is only one part of how the mind actively works with new information. In other words, information remains in working memory because the learner is actually doing something with that information. One way to retain information in working memory is through maintenance rehearsal, or repeating information over and over so you don't forget it. Maintenance rehearsal is less effective because it requires a great deal of cognitive load.

example In the movie, "The Search for Happyness," Will Smith's character repeats a telephone number out loud over and over until he can write it down so that he doesn't forget it.

Baddeley and Hitch's original model of working memory was composed of three main components; the central executive, which acts as supervisory system and controls the flow of information to and from its slave systems: the phonological loop and the visuospatial sketchpad. The slave systems are short-term storage systems dedicated to a perceptual domain (verbal and visuospatial, respectively).

5 of 25 9/13/11 7:58 AM By the Numbers http://ipt.byu.edu/isee/admin/print/index.php?story=2

The central executive serves the following functions:

binding information from a number of sources into coherent episodes coordination of the slave systems shifting between tasks or retrieval strategies selective attention and inhibition

It can be thought of as a supervisory system that controls cognitive processes.

Baddeley and Hitch have discovered that the performance of two simultaneous tasks requiring the use of two separate senses requires only slightly more cognitive load as performance of the tasks individually. In contrast, when a person tries to carry out two tasks simultaneously that use the same perceptual domain, performance is much less efficient. From this, researchers have proposed a dual theory, or the idea that the best way to learn something new is to use two different senses to present that information.

Cognitive Load Theory

Just as sensory memory limits the amount of information that gets through to working memory, working memory itself is limited in its capacity. There is only so much the brain can actively work on at a time. Because information only remains in working memory for 15-30 seconds, a learner must practice some form of maintenance rehearsal in order to keep the information in working memory. Miller (1954) first determined through a series of experiments that the capacity for working memory is 5-9 elements. This has come to be known as Miller's magic 7±2. This means that the average learner can only "work with" 5-9 different pieces of information at any one time. Not surprisingly, this capacity is even less in children, ranging from 4-7 distinct pieces of information. Cowan (2001) has discovered through recent

6 of 25 9/13/11 7:58 AM By the Numbers http://ipt.byu.edu/isee/admin/print/index.php?story=2

experiments that completely new information is actually limited to 4±1 pieces of information. Fortunately, the amount of information an individual can work with at any one time can be expanded through methods such as chunking, or grouping multiple pieces of information into meaningful clusters.

example Take 1 minute to memorize the following list of numbers.

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 0,1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987 6,75,4,39,8,7,65,4,3,33,2,4,3176,5,9,8,7,5,604,3,2

Now, without looking, quiz yourself. Which set was the easiest to remember? I'm guessing you didn't have too much trouble remembering the first list. The second list might've been a bit harder, unless you realized it as the Fibonacci sequence (add the two previous numbers). The third list is a totally random list of numbers. Even though each is the same as long, it's easier to remember more numbers when you can "chunk" them into meaningful groups.

Cognitive load studies examine the amount and type of information that a person can work with at any one time. Currently, scientists believe there are 3 types of cognitive load: intrinsic, extrinsic, and germane. Intrinsic cognitive load is thought of as the difficulty of learning certain material. It is assumed to be immutable. Extraneous cognitive load concerns the way in which information is presented to the learner. For many years, scientists focused on reducing extrinsic load by the prudent presentation of material. Recently, however, studies have examined germane cognitive load, which involves the manner in which information is processed and automated in working memory. A teacher can design learning in such a was as to help learners reduce the needed cognitive load by: (a) directing their attention to cognitive processes that are directly relevant to the construction of schemas, or (b) helping them to build automaticity.

Instructional designers have provided useful research that demonstrates how an understanding of the executive control system described above can actually play an important role in instruction. For example, because visual and auditory information are processed and handled by different sub-systems, using both simultaneously to present new information may be more effective than using one or the other independently. The dual-encoding theory proposes that information processed by two senses simultaneously records information at a deeper level than information presented by a single .

Sweller (2006) studied how learners solved complex problems. He noted that many people engaged in means-end analysis (i.e., working backward), which required a heavy cognitive load. Instead, Sweller recommended that instruction be designed using a worked-example (see the example on the right). "A worked-example includes step-by-step demonstration on how to perform a task or solve a problem" (Clark, Nguyen, & Sweller, 2006, p.

190). The Kahn academy (http://www.kahnacademy.org) is a free site dedicated to teaching mathematics through worked examples (ranging from simple 1-digit addition to advanced calculus).

One caution with worked examples is that they do not work equally well for all learners. They work best when the content is new to the learner. Worked examples should also be faded over time in favor of practice in solving actual problems.

Long-Term Memory

Are there types of knowledge that are easier to remember than other types of knowledge?

It would be difficult to keep information in working memory forever. Instead of performing maintenance rehearsal indefinitely, we break down and encode them into a long-term store. Using long-term memory consists of three stages: encoding, storage, and retrieval.

Encoding or registration (receiving, processing and combining of received information) which occurs in the short-term and working memory component of the information processing model. Storage (creation of a permanent record of the encoded information) which happens in the long-term memory component. Storage in long-term memory is thought to be indefinite. Retrieval, or recollection (calling back the stored information in response to some cue for use in a process or activity) which happens between all 3 components of the information processing model.

Long-term memory is the stored representation of all that a person knows. The items stored in long-term memory lie dormant until they are recalled (or reconstructed) back into the working memory and thus put back into to use. Three different kinds of long-term memory are: procedural, declarative, conditional.

Procedural Knowledge

Procedural knowledge is often referred to as knowing how. Procedural knowledge is implicit and is therefore often difficult to articulate. For example, describe to somebody how to balance themselves while walking. What about all the movement during swimming? Riding a bike? Learners often build up a strong automaticity for procedural knowledge, which frees up cognitive load, allowing learners to focus on more explicit types of knowledge creation. Some examples of procedural knowledge might be:

Knowledge of formal language or symbolic representations Knowledge of rules, algorithms, and procedures

Declarative knowledge is the type of knowledge that is expressed in declarative sentences or indicative propositions. This is often referred to as knowing what. Facts that you might state about a situation, what names people give to things are examples of declarative knowledge. One type of declarative knowledge that is thought to be very important is semantic knowledge. The word "semantic" means "meaning." Some researchers have found that stored memories are actually stored in terms of the meaning they have to each other instead of the exact way in which people might have experienced them. Try the following experiment:

9 of 25 9/13/11 7:58 AM By the Numbers http://ipt.byu.edu/isee/admin/print/index.php?story=2

example Read the following list of words to a group of students. They're not allowed to write anything down while you read the list: Sleep Bed Drowsy Blanket Lamp Nighttime Pillow Pajamas Darkness Dream Teddy Bear Nightlight Bathe Wash Prayers

After reading the list, ask people to write down as many words as they can remember. Give them a few minutes to do this. Next, read a list of words back to them and ask if they wrote each word down. Include a few words that clearly weren't on the list, such as "volleyball," "kitchen," and "thinking." Also include the word "tired." It's probable that about half of the people will either have written down the word "Tired" on their lists or will comment, "oh, I forgot that one!" Why? This is because of the semantic nature of long-term memory. People stored this information in their memory in terms of what these items tended to mean to them. Because "tired" shares the same meaning as many of the items on the list, they may believe it was one of the original group of words they remembered.

Another type of declarative knowledge is , which contains time and space detail about the experience of memories (Tulving, 1983). These episodes are the glue that hold together the factual, semantic memories we experience and provide personal meaning. Emotions, smells, sights, and sounds are stored in these memories and work together with semantic meaning to create stronger networks (Howard & Kahana, 2002). In fact, Roger Schank has proposed that all memory is episodic and that there is a set script that we follow for each situation. We modify the script slightly per each context. For example, he found that people were more likely to get a positive response from others when they followed the script: request + reason, as opposed to simply: request. This was the case even when the reason didn't make sense given the situation. Due to the strength of episodic memory, Schank proposed that stories are perhaps one of the most effective ways of encoding meaning in long-term memory. Thus, the telling of a story may be a powerful way to help students encode and then later recall specific information, because they bring together episodic memories with semantic and conditional knowledge.

think about it Have you ever suddenly smelled something and had a rush of memories come flooding back to you? Perhaps you've been in the middle of taking a test and you used you memory of the day the teacher taught a particular topic to you to follow a train of thought until you remembered the fact you needed to answer the question. This is often referred to as spreading activation, which is flow of thought as you connect one piece of information with another, then another, and so on, until you

10 of 25 9/13/11 7:58 AM By the Numbers http://ipt.byu.edu/isee/admin/print/index.php?story=2

arrive at the desired piece of information you were looking for.

Conceptual/Conditional Knowledge

Conceptual/Conditional knowledge is akin to wisdom. It is knowing when and why? to use specific information. Conceptual knowledge refers to a person's representation of the major concepts in a system. Examples include being able to answer questions such as, "What is the difference between the units-column and the tens-column in two-column addition problems such as 39+45=___?

Knowledge rich in relationships and understanding It is a connected web of knowledge, a network in which the linking relationships are as prominent as the discrete bits of information. Examples concepts square, square root, function, area, division, linear equation, derivative, polyhedron By definition, conceptual knowledge cannot be learned by rote. It must be learned by thoughtful, reflective learning. Is it possible to have conceptual knowledge/understanding about something without procedural knowledge?

Conceptual knowledge is also known as the kind of knowledge that may be transferred between situations. This is different from routine knowledge, which is knowledge that is applicable only to certain situations. A practical strategy that some have suggested to make use of the semantic nature of long-term knowledge, episodic memory, and conditional/conceptual knowledge is through the creation of concept maps. A concept map is a visual network of ideas that connects ideas to each other through their semantic meaning.

Loss of Memory

So, if long-term memory lasts forever, why don't we remember everything perfectly? There are several different reasons why an individual may forget what they have been taught or what they thought they had learned. states that interference occurs when the learning of something new causes of older material, due to competition between the two. The main assumption of Interference Theory is that the stored memory is intact but unable to be retrieved due to competition created by newly acquired information. Three reasons for forgetting are:

Decay: A hypothesized weakening over time of information stored in long-term memory, especially if the information is used infrequently or not at all.

Interference (proactive and retroactive): A phenomenon whereby something stored in long-term memory inhibits one's ability to remember something else correctly.

Reconstruction error: Constructing a logical but incorrect "memory" by using information retrieved from long-term memory plus one's general knowledge and beliefs about the world (think of the semantic knowledge experiment in the above example. Why did some believe "tired" was one of the original set

of words)?

Encoding Strategies

One way to remember things more effectively is to encode them (i.e., put them into long-term memory) effectively in the first place. Myriad different strategies have been proposed for getting things to stick in long term memory. There are several practical strategies for doing this.

Elaborative Rehearsal

Whereas is simply repeating information over and over, elaborative rehearsal requires a learner to elaborate on, or attach special meaning to, new concepts. Elaborative rehearsal emphasizes meaning over repetition. This often involves tapping into prior knowledge to relate new information to already formed understanding. The focus of elaborative rehearsal is the actual meaning of the learned content. Craik and Lockheart (1972) proposed a levels of processing theory that emphasized the way in which memories are learned are more important than the type of memory itself. This proposition actually changed the direction of memory research as the focus was no longer on simple storage of memories, but instead on how the memories were put into memory. Thousands of experiments were conducted that demonstrated that explaining what something means and focusing on its semantic nature resulted in better recall of that information later on. Therefore, simple talking about a concept and what it means to a person may be an effective form of encoding information.

Further research has demonstrated a few problems with levels of processing theory. First, it's difficult to distinguish between the differences that lead to "deep" vs. "shallow" elaboration. Second, it may actually be the additional time and effort associated with deep processing that results in better encoding. Third, some studies have shown that relating new information to seemingly random or unrelated prior knowledge results in better recall. This may be due to the fact that the oddity or uniqueness of the connection makes it easier to recall. For example, stating a house is like a nutshell may be more effective than elaborating how a house shelters that which is inside it.

Concept Maps

Novak (1990) proposed that concepts maps were an effective means of visualizing a learner's semantic network of understanding. Researchers have found that the effective use of knowledge maps includes four key components: (a) nodes, (b) links, (c) linking words or phrases, and (d) propositions (see figure 1)

13 of 25 9/13/11 7:58 AM By the Numbers http://ipt.byu.edu/isee/admin/print/index.php?story=2

Nodes, represented above in ellipses, contain the "what?" or the concepts of interest. Links are lines showing the connection and linking words and phrases explain those connections. Perhaps most important are the propositions, which is the combination of any two nodes and the label that connects them. These are important because they relay the meaning in a concept map. Researchers have proposed that concepts maps are useful because they reveal students' network of understanding.

Mnemonics

A mnemonic is the association of unrelated information. For example, while a desk and dental hygiene

14 of 25 9/13/11 7:58 AM By the Numbers http://ipt.byu.edu/isee/admin/print/index.php?story=2

might seem to have nothing to do with each other, I might use the desk to remind myself that I have to look in all the nooks and crannies to find what I want and get all the undesirables out of my mouth. Several methods have been proposed for working with

First-Letter

An acronym simply takes the first letter of each word in a list that a person must remember and creates a word out of it. You might use the acronym HOMES to remember the names of the 5 great lakes, for example (Huron, Ontario, Michigan, Eerie, and Superior). Can you identify what these mnemonics stand for?

think about it ROYGBIV SOHCAHTOA

Another first-letter mnemonic technique is an acrostic, which involves making a sentence out of the first letter of the words you are trying to remember. For example, "Kings Play Chess on Fine Grained Sand," is a mnemonic I learned for remembering the classification taxonomy of living things (Kingdom, Phylum, Class, Family, Genus, Species).

Chain mnemonic

A chain mnemonic involves using one item to trigger the recall of the next item in a list. This is often done by putting the items into a story. For example, to remember the order of the first five U.S. Presidents (Washington, Adams, Jefferson, Madison, and Monroe), I might create the following story:

I was in Washington, buying some Adam's apples, when my son, Jefferson asked if we could go to Madison square gardens. I told him we could go to Monroe (said like "tomorrow").

Keyword method

The Keyword method is often used in language learning. It involves using one word that sounds like or reminds you of another word or set of words. For example, to learn the word "here" in Spanish (aqui), I might think "Here is a key!"

Loci-method

The loci-method involves using locations to remember the items in a list. This works best when the learner uses a location s/he is very familiar with. For example, to remember a shopping list, you might create a story of where these items belong in your kitchen. Try it the next time you go shopping and see how accurate you are without writing anything down.

Peg-type mnemonic

Peg-type mnemonics have been used to remember elaborate, long-lists of information. The notion is to "hang" each piece of information on a related set of "pegs." For example, to remember the 4 components to learning through modelling proposed by Bandura in his book, Social Learning, (attention, retention, production, motivation), my students came up with a peg-type mnemonic using the face. It went like this.

If I want to learn by watching somebody else, I attend to them (point to your eyes), remember/retain what they did (point to your brain), produce it myself (point to your mouth), and be motivated to do it (smile).

Whole - Part - Whole

This method of encoding is useful in learning skills requiring procedural knowledge (as well as some declarative tasks). For example, in a sports situation, a learner might begin by swimming one lap in a pool. His coach observes him and gives feedback on the different parts that he needs to work on. The athlete then practices those different parts in isolation, moving focus from one to the next, gradually increasing the use of each. Whole - part - whole has been shown to be particularly effective for adults.

Retrieval Strategies

Herman Ebbinghaus, a pioneer in research on memory, conducted several experiments on himself to try and remember lists of words and nonsense syllables. In recalling lists of information, he discovered that there was a curious effect that occurred; the ease or difficulty of recalling that information had to do with where it fell in the order of when he learned it. Read the following and then quickly cover it up:

example David, Robyn, Rebecca, Michael, Peter, Dan, Matt, Sarah, Liz, Adam

Now, try and recall the list as well as possible. Which names were easiest to remember? Most difficult? Research has found that people are almost twice as likely to remember the items at the beginning and end than they are to remember those in the middle. Additionally, those at the end tend to be the easiest to recall due to the recency effect (the most recent is the easiest to recall, to a certain point). This is called the serial-position effect.

Rote Learning

Perhaps the most frequently used method for teaching a new method is through simple repetition (no pun intended ;). Rote learning has typically been disparaged because of its brute approach that proposes that learning is simply the act of constant repetition. While there are certainly less effective methods of rote learning, there are also very effective rote learning techniques. One less effective technique is massed practice, or attempting to learn a large amount of material in a single sitting, commonly referred to as "cramming." Spreading out the learning of repeated material over time appears to be a much more effective encoding technique. This is referred to as distributed practice.

A very effective rote-learning technique that you have likely used is songs to repeat and remember information. For example, how do you remember what position the letter "V" is in the alphabet? What about the book of Habakuk in the Old Testament? Did you find yourself singing a song? That's because you likely used a song to learn the order of these items by rote. What songs have you learned in school?

Metacognition

Metacognition means "thinking about thinking." It involves the use of all the three types of knowledge mentioned earlier in Long-term memory (procedural, declarative, and conditional/conceptual). Meta-cognition is considered a higher-order thinking skill because it makes students aware of their own knowledge structures, how they are formed, and how they are used. Each person's metacognitive abilities are different. As a teacher, it's most important to help students learn techniques to help them think about their own thinking and to see it objectively so that they might be able to improve upon it. The skills that help students to improve their metacognition involve planning, monitoring and evaluating. Planning is deciding how much time to dedicate to a task, what parts of the task to learn

17 of 25 9/13/11 7:58 AM By the Numbers http://ipt.byu.edu/isee/admin/print/index.php?story=2

first, and the order in which one will learn it. Monitoring is seeing how one is doing during learning (e.g., "do I understanding?," "what am I struggling with?"). Evaluating is the process of reflecting on and judging the quality of the strategies one uses. This is NOT a judgment of whether or not you understand the material, but rather how well your strategies for learning the material function for you.

The teaching of learning strategies has been shown to be an effective technique for reinforcing metacognition. Derry (1989) proposed the following (taken from pp. 330 of Anita Woolfolk's book, Educational Psychology, 11th edition).

Glossary

ACRONYM No definition provided

ACROSTIC A mnemonic device in which the first letters of a the words to remember are represented by a sentence of words that also start with those letters, in the same order.

ADVANCE ORGANIZER A cognitive device that primes students to pay attention to specific aspects of a lesson prior to being given that information.

ALGORITHM Algorithm: a prescribed sequence of steps that, if selected and followed correctly, guarantees a correct solution

ANALOGICAL THINKING Analogical thinking: limits the search for solutions to situations that are most similar to the one at hand

ATTENTION Attention: The focusing of mental processes on particular environmental stimuli. Attention is defined as a cluster of integrated events and processes that determine which stimuli receive further processing.

AUTOMATICITY Automaticity: The ability to respond quickly and efficiently while mentally processing or physically performing a task.

CENTRAL EXECUTIVE Central Executive: The part of working memory that is responsible for monitoring and directing attention and other mental resources.

CHUNKING Chunking: Grouping individual groups of data into meaningful larger units.

COGNITION Cognition is often used as a scientific term for the process of thought and the study of how the human brain thinks and (3,5).

COGNITIVE PSYCHOLOGY Cognitive psychology (also known as cognitivism) explores how the human brain thinks (7).

CONCEPT MAPS Visual representation of a learner's conceptual network of understanding.

CONCEPTUAL KNOWLEDGE Conceptual knowledge: A form of mental representation that reflects an understanding of declarative or procedural knowledge.

DECAY Decay: A hypothesized weakening over time of information stored in long-term memory, especially if the information is used infrequently or not at all.

DECLARATIVE KNOWLEDGE Declarative knowledge: Knowledge related to "what is

DISTRIBUTED PRACTICE Learning information repeatedly spread out over time.

DUAL ENCODING THEORY A theory that information encoded using two different senses is better remembered than when using only a single sense.

DUAL-ENCODING THEORY Encoding memories using two different senses at the same time.

ELABORATIVE REHEARSAL Elaborative rehearsal: A cognitive process in which learners expand on new information based on what they already know.

ENCODING recording information to Long-Term memory.

EPISODIC MEMORY The contextual information that includes temporal, spatial, and affective (i.e., emotional) information associated with particular events at the time a memory is formed.

EXTRANEOUS COGNITIVE LOAD The way information is presented to the learner. The teacher is in control of this process.

FORGET the decay of memories.

FUNCTIONAL FIXEDNESS Functional fixedness: the inability to use objects or tools in a new way

GERMANE COGNITIVE LOAD The type of cognitive load directly related to processing, constructing and automating schema.

HEURISTIC Heuristic: a general problem-solving strategy that relies on common sense or rule of thumb.

HIGH-ROAD TRANSFER High-road transfer: applying abstract knowledge learned in one context to a different situation.

INFORMATION PROCESSING MODELS Information processing models identify general rules and procedures of how the human brain processes information (7).

INFORMATION PROCESSING THEORY Information processing theory is a perspective that believes the human mind processes information according to rules and strategies similar to that of a computer (9).

INTERFERENCE (PROACTIVE AND Interference (proactive and retroactive): A phenomenon whereby RETROACTIVE something stored in long-term memory inhibits one's ability to remember something else correctly.

INTRINSIC COGNITIVE LOAD The natural difficulty of learning a task. This can't be changed.

LONG-TERM MEMORY Long-term memory: The component of memory that holds knowledge and skills for a relatively long period of time

LOW-ROAD TRANSFER Low-road transfer: spontaneous, automatic transfer of highly practiced skills.

MAINTENANCE REHEARSAL Maintenance rehearsal: Repetition of information over and over to keep it "fresh"" in working memory. "

MASSED PRACTICE Cramming.

MEANS-ENDS ANALYSIS Means-ends analysis: a heuristic in which the main problem-solving goal is divided into subgoals.

MINDFUL ABSTRACTION Mindful Abstraction: a defining feature of high-road transfer in which information that is consciously and actively learned is retrieved and applied to a new situation, guided by one?s metacognition.

MNEMONIC DEVICES Mnemonic Devices: A special memory aid or trick designed to help students learn and remember a specific piece of information.

NEGATIVE TRANSFER Negative Transfer: occurs when previous learning hinders learning on a new task.

PERCEIVED Perception is the first stage of recognizing a piece of information (stimulus). Our brains perceive thousands of stimuli at once, but usually throw that information out because we judge it not to be immediately important.

PERCEPTION The unconscious act of recognizing a stimulus.

PHONOLOGICAL LOOP Phonological loop: Part of working memory. A system for verbal and sound information of about 1.5 to 2 seconds.

POSITIVE TRANSFER Positive transfer: occurs when previous learning facilitates learning on new task.

PRIOR KNOWLEDGE Prior knowledge: Process of reminding students of things they have already learned relative to a new topic.

PROBLEM SOLVING Problem solving: the means we use to reach a goal in spite of an obstacle or obstacles.

PROCEDURAL KNOWLEDGE Procedural Knowledge: Knowledge concerning how to perform a certain skill or task

RECALL Recall: A memory task in which one must retrieve information in its entirety from long-term memory.

RECONSTRUCTION ERROR Reconstruction error: Constructing a logical but incorrect "memory"" by using information retrieved from long-term memory plus one's general knowledge and beliefs about the world. "

REHEARSAL Rehearsal : A cognitive process in which information is repeated over and over as a possible way of learning and remembering it. When it is used to maintain information in working memory, it is called maintenance rehearsal. When it is connected with prior knowledge and expanded upon, it is called elaborative rehearsal.

RETRIEVAL CUES Retrieval cues: A hint about where to "look"" for a piece of information in long-term memory. "

SEMANTIC KNOWLEDGE Knowledge related to the meaning of connections between concepts, or factual information.

SEMANTIC MEMORY : your memory for meanings and general (impersonal) facts.

SENSORY MEMORY Sensory memory: A component of memory that holds incoming information in an unanalyzed form for a very brief period of time (probably less than a second for visual input and two or three seconds for auditory input).

SERIAL-POSITION EFFECT The effect whereby information learned first and last is remembered most easily and information in the middle is only recalled half as

often.

SPREADING ACTIVATION The process of connecting one memory with an already formed memory and activating prior memories until arriving at the desired information.

VISUOSPATIAL SKETCHPAD Visuospatial sketchpad: Part of working memory. A holding system for visual and spatial information.

WORKING BACKWARD STRATEGY Working backward strategy: a heuristic in which you start with the final goal and think backward to identify the steps that would be needed to reach that goal

WORKING MEMORY/SHORT-TERM Working memory/Short-term memory: A component of memory MEMORY that holds and processes a limited amount of information; also known as short-term memory. The duration of information stored in working memory is probably about 5 to 20 seconds.
