Compare and Contrast Two Models Or Theories of One Cognitive Process with Reference to Research Studies
! The following sample is for the learning objective: Compare and contrast two models or theories of one cognitive process with reference to research studies. What is the question asking for? * A clear outline of two models of one cognitive process. The cognitive process may be memory, perception, decision-making, language or thinking. * Research is used to support the models as described. The research does not need to be outlined in a lot of detail, but underatanding of the role of research in supporting the models should be apparent.. * Both similarities and differences of the two models should be clearly outlined. Sample response The theory of memory is studied scientifically and several models have been developed to help The cognitive process describe and potentially explain how memory works. Two models that attempt to describe how (memory) and two models are memory works are the Multi-Store Model of Memory, developed by Atkinson & Shiffrin (1968), clearly identified. and the Working Memory Model of Memory, developed by Baddeley & Hitch (1974). The Multi-store model model explains that all memory is taken in through our senses; this is called sensory input. This information is enters our sensory memory, where if it is attended to, it will pass to short-term memory. If not attention is paid to it, it is displaced. Short-term memory Research. is limited in duration and capacity. According to Miller, STM can hold only 7 plus or minus 2 pieces of information. Short-term memory memory lasts for six to twelve seconds. When information in the short-term memory is rehearsed, it enters the long-term memory store in a process called “encoding.” When we recall information, it is retrieved from LTM and moved A satisfactory description of back into STM. -

HIRSCH, DALE A., Ph.D., August 2017 Educational Psychology DISSOCIATION BETWEEN DECLARATIVE AND PROCEDURAL MECHANISMS IN LONG-TERM MEMORY (66 pp.) Director of Dissertation: Bradley Morris The purpose of this study was to investigate the potential dissociation between declarative and procedural elements in long-term memory for a facilitation of procedural memory (FPM) paradigm. FPM coupled with a directed forgetting (DF) manipulation was utilized to highlight the dissociation. Three experiments were conducted to that end. All three experiments resulted in facilitation for categorization operations. Experiments one and two additionally found relatively poor recognition for items that participants were told to forget despite the fact that relevant categorization operations were facilitated. Experiment three resulted in similarly poor recognition for category names that participants were told to forget. Taken together, the three experiments in this investigation demonstrate a clear dissociation between the procedural and declarative elements of the FPM task. -

By Maximilian Fey Under the mentorship of Dr. Karen Naufel ABSTRACT Previous research has found that individuals with high working memory have greater recall capabilities than those with low working memory (Unsworth, Spiller, & Brewers, 2012). Research did not test the extent to which cues affect one’s recall ability in relation to working memory. The present study will examine this issue. Participants completed a working memory measure. Then, they were provided with cued recall tasks whereby they recalled Facebook friends. The cues varied to be no cues, ambiguous cues high in imageability, and cues directly related to Facebook. The results showed that there was no difference between individual’s ability to recall their Facebook friends and their working memory scores. -

Sleep is critical for consolidating hippocampal memory of wake experiences into the neocortex. Understanding representations of neural codes of hippocampal-neocortical networks during sleep would reveal important circuit mechanisms on memory consolidation, and provide novel insights into memory and dreams. Although sleep-associated ensemble spike activity has been investigated, identifying the content of memory in sleep remains challenging. -
Spatial Information Modulates the Neurocognitive Dynamics of Episodic Autobiographical Memory Retrieval
Spatial Information Modulates the Neurocognitive Dynamics of Episodic Autobiographical Memory Retrieval by Melissa Hebscher A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Psychology University of Toronto © Copyright by Melissa Hebscher, 2018 Spatial Information Modulates the Neurocognitive Dynamics of Episodic Autobiographical Memory Retrieval Melissa Hebscher Doctor of Philosophy Department of Psychology University of Toronto 2018 Abstract Episodic autobiographical memory (EAM) enables reliving past experiences, recalling the sensory information associated with that event. Spatial information is thought to play an early and important role in EAM, contributing to the dynamics of retrieval. Using a combination of behavioural, neuroimaging, and neurostimulation approaches, this dissertation aimed to examine the temporal dynamics of EAM and the role spatial information plays in its retrieval. Chapter 2 demonstrated a temporal precedence for spatial information at the behavioural level, but importantly found high individual variability in early recall of spatial information. Further, individual differences in spatial aspects of EAM were reflected in hippocampal and precuneus grey matter volumes. Chapter 3 examined the temporal dynamics of EAM at the neural level using magnetoencephalography (MEG). While cueing individuals with familiar locations altered the dynamics of retrieval, it did not confer an early neural advantage. Together with the findings from Chapter 2, these results indicate that early spatial information alters the dynamics of EAM retrieval, but does not play a ubiquitous or automatic role in EAM. This study also found that spatial perspective during EAM retrieval was associated with a well-established neural component of episodic memory recollection. Transcranial magnetic stimulation (TMS) administered to the precuneus disrupted this association, demonstrating that this region is crucially involved in neural processing of spatial perspective during EAM. -
Working Memory and the Organization of Brain Systems
4818 • The Journal of Neuroscience, April 30, 2008 • 28(18):4818–4822 Behavioral/Systems/Cognitive Working Memory and the Organization of Brain Systems Yael Shrager,1 Daniel A. Levy,2 Ramona O. Hopkins,3 and Larry R. Squire4 1University of California, San Diego, La Jolla, California 92093, 2Weizmann Institute of Science, Rechovot 76100, Israel, 3Brigham Young University, Provo, Utah 84602, and 4Veterans Affairs Healthcare System, San Diego, California 92161 Working memory has historically been viewed as an active maintenance process that is independent of long-term memory and indepen- dent of the medial temporal lobe. However, impaired performance across brief time intervals has sometimes been described in amnesic patients with medial temporal lobe damage. These findings raise a fundamental question about how to know when performance depends on working memory and when the capacity for working memory has been exceeded and performance depends on long-term memory. We describe a method for identifying working memory independently of patient performance. We compared patients with medial temporal lobe damage to controls who were given either distraction or no distraction between study and test. In four experiments, we found concordance between the performance of patients and the effect of distraction on controls. The patients were impaired on tasks in which distraction had minimal effect on control performance, and the patients were intact on tasks in which distraction disrupted control performance. We suggest that the patients were impaired when the task minimally depended on working memory (and instead depended substantially on long-term memory), and they performed well when the task depended substantially on working memory. -

Dissociating Visuo-Spatial and Verbal Working Memory: It's All in the Features
Memory & Cognition https://doi.org/10.3758/s13421-018-0882-9 Dissociating visuo-spatial and verbal working memory: It’sall in the features Marie Poirier1 & James M. Yearsley1 & Jean Saint-Aubin2 & Claudette Fortin3 & Geneviève Gallant2 & Dominic Guitard2 # The Author(s) 2018 Abstract Echoing many of the themes of the seminal work of Atkinson and Shiffrin (The Psychology of Learning and Motivation, 2; 89–195, 1968), this paper uses the feature model (Nairne, Memory & Cognition, 16, 343–352, 1988;Nairne,Memory & Cognition, 18; 251– 269, 1990; Neath & Nairne, Psychonomic Bulletin & Review, 2;429–441, 1995) to account for performance in working-memory tasks. The Brooks verbal and visuo-spatial matrix tasks were performed alone, with articulatory suppression, or with a spatial suppression task; the results produced the expected dissociation. We used approximate Bayesian computation techniques to fit the feature model to the data and showed that the similarity-based interference process implemented in the model accounted for the data patterns well. We then fit the model to data from Guérard and Tremblay (2008, Journal of Experimental Psychology: Learning, Memory, and Cognition, 34,556–569); the latter study produced a double dissociation while calling upon more typical order reconstruction tasks. Again, the model performed well. The findings show that a double dissociation can be modelled without appealing to separate systems for verbal and visuo-spatial processing. The latter findings are significant as the feature model had not been used to model this type of dissociation before; importantly, this is also the first time the model is quantitatively fit to data. For the demonstration provided here, modularity was unnecessary if two assumptions were made: (1) the main difference between spatial and verbal working-memory tasks is the features that are encoded; (2) secondary tasks selectively interfere with primary tasks to the extent that both tasks involve similar features. -
Working Memory
Working Memory Chapter 4 1 Working Memory Some memories are very fragile and go into oblivion very quickly. Working memory is one such memory. 1. Try this. Do this mentally. Write your answers on paper. a. 7 X 9 = 63 b. 74 X 9 = 666 c. 74 X 96 = 7104 2 Working Memory (WM) 1. We know attention is limited. So information that gets to memory is also limited. Thus capacity of working memory is limited. 2. Working memory is brief, immediate memory we use for current information. A portion of working memory coordinates ongoing mental activities. 3. Working memory has been known as short-term memory, and is contrasted from long-term. Some investigators believe the two are the same (Nairne, 2002). 3 1 Classic Research on Working Memory (Short-term Memory) 4 Short-term Memory In the 19th century, Sir George Hamilton discovered that he could accurately store about 7 items (marbles) in memory if he glanced at the items quickly. If the items were more than 7 his accuracy decreased. Sir George Hamilton 5 Short-term Memory 1. Miller (1956) wrote, “The magical number seven plus or minus two: some limits on our capacity for processing information”. 2. Miller suggested that the capacity of our short-term memory was small. We could store about 5-9 items in it. 3. He also showed that items could be “chunked”, which would increase our memory capacity. George Miller 6 2 Try This ! C T A I I L T C S F R O R E C A L L !

The Method of Loci in Virtual Reality: Explicit Binding of Objects to Spatial Contexts Enhances Subsequent Memory Recall
Journal of Cognitive Enhancement https://doi.org/10.1007/s41465-019-00141-8 ORIGINAL RESEARCH The Method of Loci in Virtual Reality: Explicit Binding of Objects to Spatial Contexts Enhances Subsequent Memory Recall Nicco Reggente1 & Joey K. Y. Essoe1 & Hera Younji Baek1 & Jesse Rissman1,2 Received: 7 January 2019 /Accepted: 7 June 2019 # Springer Nature Switzerland AG 2019 Abstract The method of loci (MoL) is a well-known mnemonic technique in which visuospatial spatial environments are used to scaffold the memorization of non-spatial information. We developed a novel virtual reality-based implementation of the MoL in which participants used three unique virtual environments to serve as their “memory palaces.” In each world, participants were presented with a sequence of 15 3D objects that appeared in front of their avatar for 20 s each. The experimental group (N = 30) was given the ability to click on each object to lock it in place, whereas the control group (N = 30) was not afforded this functionality. We found that despite matched engagement, exposure duration, and instructions emphasizing the efficacy of the mnemonic across groups, participants in the experimental group recalled 28% more objects. We also observed a strong relation- ship between spatial memory for objects and landmarks in the environment and verbal recall strength. These results provide evidence for spatially mediated processes underlying the effectiveness of the MoL and contribute to theoretical models of memory that emphasize spatial encoding as the primary currency of mnemonic function. Keywords Memory enhancement . Method of loci . Virtual reality Introduction the MoL is a complicated, time-consuming mnemonic to imple- ment, but in fact, it is rather straightforward. -

Although sleep problems development of important cognitive functions, such as in infancy, early childhood, and middle childhood were not working memory, and may have the potential for negative directly related to adolescent working memory, sleep behavioral consequences, such as risk-taking. In this way, problems during adolescence were associated with poorer sleep problems may be particularly harmful for youth— adolescent working memory. In turn, these deficits in whose cognitive abilities are still developing and who are working memory were related to greater risk taking in late more susceptible to risky behavior. Using data from a large, adolescence. In summary, the present results suggest that national, longitudinal study, continuity and change in sleep sleep problems in earlier periods are indicative of risk for problems were examined from 2 to 15 years of age and sleep problems later in development, but that sleep problems associated with deficits in working memory at age 15 and in adolescence contribute uniquely to deficits in working risk taking behaviors at age 18.
