Complex Mental Processes

Complex Mental Processes

  • Areas covered: Reasoning, Problem Solving, Judgment, and Decision Making

  • Course: PSYC3226, Dr. Knickerbocker, ECU

Types of Thinking

  • Problem Solving:

    • Develop solutions to obstacles and achieve goals.

  • Judgment and Decision Making:

    • Selecting a choice from a list of options.

  • Reasoning:

    • Ability to assess the validity of conclusions.

Reasoning

Types of Reasoning

  • Inductive Reasoning:

    • Predicts new cases based on observed cases.

    • Example: Observations lead to a forecast about unobserved cases.

  • Deductive Reasoning:

    • Starts with general premises to derive conclusions.

    • Example: Beliefs and hypotheses lead to logical outcomes.

Types of Evidence

  • Confirming Evidence:

    • Supports theories; example of a rooster crowing followed by sunrise.

  • Disconfirming Evidence:

    • Challenges theories; needs to be tested by lack of a predicted outcome.

Reasoning Challenges

Confirmation Bias

  • Responding more to evidence that confirms beliefs.

  • Less responsiveness to evidence that contradicts beliefs.

Research on Confirmation Bias

  • Wason's (1966) tasks demonstrated that individuals sought confirming but not disconfirming evidence.

  • Individuals struggled to identify the rule for sequences; confirmed insights align with existing beliefs.

Reinterpreting Evidence

  • Confirmation: Accepted at face value.

  • Disconfirmation: Scrutinized closely.

  • Example of gambling outcomes influencing perception of wins/losses.

Belief Perseverance

  • Persistence in believing a claim despite contradictory evidence.

Deductive Reasoning

Categorical Syllogisms

  • Structure of logical arguments comprised of premises leading to a conclusion.

    • Example: All M are B; All D are M; Therefore, all D are B.

Validity of Syllogisms

  • Testing validity through logical structures. Example evaluates the conclusion validity based on premises.

Errors in Deductive Reasoning

  • Belief Bias:

    • Believing arguments that align with pre-existing opinions, irrespective of logical validity.

Conditional Statements

Basic Structure

  • Conditional Statement Format: If X, then Y.

  • Common fallacies: Affirming the consequent and denying the antecedent.

Wason’s Four-Card Task

  • Task designed to test understanding of conditional reasoning.

  • Most participants fail to identify the cards that properly test the rule.

Problem Solving

Problem Solving Process

  • Starts with goal setting and determining steps necessary to achieve it.

  • Navigational analogy: initial state vs. goal state; operators and path constraints.

Use of Mental Imagery

  • Visualizing problems can aid in finding solutions (e.g., the "bookworm" problem).

  • Affects understanding of problem dimensions.

Using Analogies in Problem Solving

  • Expert problem solvers frequently employ analogies to simplify complex problems.

  • Understanding deeper structures allows more effective strategy development.

Creative Thinking in Problem Solving

Functional Fixedness

  • Rigidity in thinking about an object's purpose can hinder problem-solving.

  • Example includes using everyday objects in innovative ways (e.g., using pliers as weights).

Reframing Problem Sets

  • Exposure to similar problems can lead to inflexibility in solving new, unique problems.

Judgment Assessment

Heuristics

  • Mental shortcuts used in decision making favoring efficiency over accuracy.

  • Common biases include attribute substitution.

Availability Heuristic

  • Judging frequency or likelihood based on ease of retrieving examples.

    • Examples: personal experiences vs. general statistics in evaluations.

Representativeness Heuristic

  • Assessments made based on how closely examples match prototypes or stereotypes.

  • Common errors involve neglecting base-rate information.

Decision Making Models

Prescriptivist vs. Descriptivist Models

  • Prescriptive Models: Ideal decision-making processes.

  • Descriptive Models: Actual processes of decision-making based on circumstances.

Rational Decision Making

  • Utility Theory: Calculating expected values and maximizing utilities.

  • Framing effect influences decision choice based on perspectives.

Irrational Decision Making

  • Prospect Theory: Loss aversion leads individuals to value losses more than equivalent gains.

  • Sunk-Cost Effect: Continued investment in unfavorable options due to prior commitments.

  • Omission Bias: Prefer inaction to action due to risk of harm.

Affective Heuristic

  • Emotional responses influence decision-making.

  • Anticipation of regret shapes choices.
