Logical Reasoning
Chapter 2 Logical Reasoning All human activities are conducted following logical reasoning. Most of the time we apply logic unconsciously, but there is always some logic ingrained in the decisions we make in order to con- duct day-to-day life. Unfortunately we also do sometimes think illogically or engage in bad reasoning. Since science is based on logical thinking, one has to learn how to reason logically. The discipline of logic is the systematization of reasoning. It explicitly articulates principles of good reasoning, and system- atizes them. Equipped with this knowledge, we can distinguish between good reasoning and bad reasoning, and can develop our own reasoning capacity. Philosophers have shown that logical reasoning can be broadly divided into two categories—inductive, and deductive. Suppose you are going out of your home, and upon seeing a cloudy sky, you take an umbrella along. What was the logic behind this commonplace action? It is that, you have seen from your childhood that the sky becomes cloudy before it rains. You have seen it once, twice, thrice, and then your mind has con- structed the link “If there is dark cloud in the sky, it may rain”. This is an example of inductive logic, where we reach a general conclusion by repeated observation of particular events. The repeated occurrence of a particular truth leads you to reach a general truth. 2 Chapter 2. Logical Reasoning What do you do next? On a particular day, if you see dark cloud in the sky, you think ‘today it may rain’. You take an um- brella along. -

Evolutionary Psychology and Human Reasoning: Testing the Domain-Specificity Hypothesis Through Wason Selection Task
Evolutionary Psychology and Human Reasoning: Testing the Domain-Specificity Hypothesis through Wason Selection Task Fabrizio Ferrara ([email protected])* Amedeo Esposito ([email protected])* Barbara Pizzini ([email protected])* Olimpia Matarazzo ([email protected])* *Department of Psychology - Second University of Naples, Viale Ellittico 31, Caserta, 81100 Italy Abstract during phylogenetic development. Both these approaches, albeit based on a different conception of the human mind, The better performance in the selection task with deontic rules, compared to the descriptive version, has been share the assumption that it is better equipped for reasoning interpreted by evolutionary psychologists as the evidence that with general (e.g. Cummins 1996, 2013) or specific (e.g. human reasoning has been shaped to deal with either global or Cosmides, 1989; Cosmides & Tooby, 2013) deontic norms specific deontic norms. An alternative hypothesis is that the rather than with epistemic concepts (i.e. the concepts related two types of rules have been embedded in two different forms to knowledge and belief). of reasoning, about and from a rule, the former demanding Experimental evidence achieved mainly by means of the more complex cognitive processes. In a between-subjects study with 640 participants we manipulated the content of the selection task (Wason, 1966) is thought to support this rule (deontic vs. social contract vs. precaution vs. descriptive) claim. In the original formulation, this task consists in and the type of task (reasoning about, traditionally associated selecting the states of affairs necessary to determine the to indicative tasks, vs. reasoning from, traditionally associated truth-value of a descriptive (or indicative) rule expressed to deontic tasks). -

They Fall for Common Fallacies The dull mind, once arriving at an inference that flatters the desire, is rarely able to retain the impression that the notion from which the inference started was purely problematic. ― George Eliot, in Silas Marner In the last chapter we discussed passages where bright individuals with PhDs violated common fallacies. Even the brightest among us fall for them. As a result, we should be ever vigilant to keep our critical guard up, looking for fallacious reasoning in lectures, reading, viewing, and especially in our own writing. None of us are immune to falling for fallacies. -

Mapping Mind-Brain Development: Towards a Comprehensive Theory
Journal of Intelligence Review Mapping Mind-Brain Development: Towards a Comprehensive Theory George Spanoudis 1,* and Andreas Demetriou 2,3 1 Psychology Department, University of Cyprus, 1678 Nicosia, Cyprus 2 Department of Psychology, University of Nicosia, 1700 Nicosia, Cyprus; [email protected] 3 Cyprus Academy of Science, Letters, and Arts, 1700 Nicosia, Cyprus * Correspondence: [email protected]; Tel.: +357-22892969 Received: 20 January 2020; Accepted: 20 April 2020; Published: 26 April 2020 Abstract: The relations between the developing mind and developing brain are explored. We outline a theory of intellectual development postulating that the mind comprises four systems of processes (domain-specific, attention and working memory, reasoning, and cognizance) developing in four cycles (episodic, realistic, rule-based, and principle-based representations, emerging at birth, 2, 6, and 11 years, respectively), with two phases in each. Changes in reasoning relate to processing efficiency in the first phase and working memory in the second phase. Awareness of mental processes is recycled with the changes in each cycle and drives their integration into the representational unit of the next cycle. Brain research shows that each type of processes is served by specialized brain networks. Domain-specific processes are rooted in sensory cortices; working memory processes are mainly rooted in hippocampal, parietal, and prefrontal cortices; abstraction and alignment processes are rooted in parietal, frontal, and prefrontal and medial cortices. Information entering these networks is available to awareness processes. Brain networks change along the four cycles, in precision, connectivity, and brain rhythms. Principles of mind-brain interaction are discussed. Keywords: brain; mind; development; intelligence; mental and brain changes; brain networks 1. -
Deductive Reasoning & Decision Making Deductive Reasoning
Deductive Reasoning & Decision Making Chapter 12 Complex Cognitive Tasks Deductive reasoning and decision making are complex cognitive tasks that are part of the thinking process. Thinking Problem Deductive Decision Solving Reasoning Making Deductive Reasoning 1 Deductive Reasoning Is a process of thinking in a logical way, where conclusion are drawn from the information given, for example: if there are clouds in the sky then it will rain. Information Conclusion Deductive Reasoning There are two kinds of deductive reasoning: 1. Conditional Reasoning 2. Syllogisms Conditional Reasoning Conditional reasoning (or propositional reasoning), tells us about the relationship between conditions. Conditional reasoning consists of true if- then statements, used to deduce a true conclusion. Though the premises may be true the conclusions can be valid or invalid. 2 Valid Conclusion If a student is in cognitive psychology, Then she must have completed her Premises general psychology requirements. Jenna is in cognitive psychology class Observation So Jenna must have completed her general psychology requirements. Conclusion Valid Conclusion If a student is in cognitive psychology, Then she must have completed her Premises general psychology requirements. David has NOT completed his general psychology requirements. Observation So David must NOT be in cognitive psychology class. Conclusion Valid Conclusions Affirming If p is true then q is true Modus the p is true Valid ponens antecedent q is true If Newton was a scientist, then he was a person Newton was a scientist Newton was a person If p is true then q is true Denying the Modus q is not true Valid consequent tollens p must be not true If an officer is a general, then he was a captain. -
The Field of Logical Reasoning

Minsky Other Ways… • Logical Reasoning comes from Age-Old disciplines/practices of REASON. • But REASON is only ONE human characteristic • Other methods/processes are drawn from the strengths of other characteristics Other Human Characteristics: • John Ralston Saul (Unconscious Civilization, 1995) lists SIX Human Characteristics • They are (alphabetically, so as not to create a hierarchy): • Common Sense • Intuition • Creativity • Memory • Ethics • Reason Reason is not Superior • While this presentation focuses on the practices of REASON, it is necessary to actively engage our collective notions rooted in: • Common Sense (everyday understandings) • Creativity (new, novel approaches) • Ethics (relative moral high-ground) • Intuition (gut instinct) • Memory (history, stories) …in order to have a holistic/inclusive approach to reasonable doubt and public participation.

Why Do Humans Reason? Arguments for an Argumentative Theory
BEHAVIORAL AND BRAIN SCIENCES (2011) 34, 57–111 doi:10.1017/S0140525X10000968 Why do humans reason? Arguments for an argumentative theory Hugo Mercier Philosophy, Politics and Economics Program, University of Pennsylvania, Philadelphia, PA 19104 [email protected] http:// sites.google.com/site/hugomercier/ Dan Sperber Jean Nicod Institute (EHESS-ENS-CNRS), 75005 Paris, France; Department of Philosophy, Central European University, Budapest, Hungary [email protected] http:// www.dan.sperber.fr Abstract: Reasoning is generally seen as a means to improve knowledge and make better decisions. However, much evidence shows that reasoning often leads to epistemic distortions and poor decisions. This suggests that the function of reasoning should be rethought. Our hypothesis is that the function of reasoning is argumentative. It is to devise and evaluate arguments intended to persuade. Reasoning so conceived is adaptive given the exceptional dependence of humans on communication and their vulnerability to misinformation. A wide range of evidence in the psychology of reasoning and decision making can be reinterpreted and better explained in the light of this hypothesis. Poor performance in standard reasoning tasks is explained by the lack of argumentative context. When the same problems are placed in a proper argumentative setting, people turn out to be skilled arguers. Skilled arguers, however, are not after the truth but after arguments supporting their views. This explains the notorious confirmation bias. This bias is apparent not only when people are actually arguing, but also when they are reasoning proactively from the perspective of having to defend their opinions. Reasoning so motivated can distort evaluations and attitudes and allow erroneous beliefs to persist.
