Study Notes

Problem Solving Approaches

  • Problem solving arises when a clear goal exists but the solution is unknown.
  • Key approaches include behaviourist, Gestalt, inductive, and deductive reasoning.

Behaviourist Approach

  • Focus: Observable behaviour.
  • Emphasis: Stimulus-response associations.
  • Method: Trial and error.
  • Thorndike's cat experiments (puzzle boxes): Demonstrated incremental learning in animals.
  • Thorndike's Law of Effect: Positive consequences reinforce responses, negative consequences weaken them; problem solving is incremental, not sudden.

Gestalt Approach

  • Focus: Insight.
  • Kohler's chimpanzee experiments (banana): Demonstrated insightful problem solving using tools.
  • Insightful solutions are sudden, unlike incremental trial and error.

Creative Thinking (Wallas)

  • Stages of creative thinking:
    • Preparation: Active information gathering and problem work.
    • Incubation: Setting the problem aside.
    • Illumination: Sudden insight into a solution.
    • Verification: Testing and refining the solution.

Evidence for Incubation

  • Silveria (1971): Necklace problem. Incubation benefited lower-ability individuals.
  • Murray and Denny (1969): Incubation can hinder high-ability individuals, interrupting their workflow. This hindrance applies more to complex or difficult problems.

Barriers to Successful Problem Solving

  • Mental Set/Einstellung: Pre-existing successful approaches hinder new solutions.
  • Luchins' water jug problem: Demonstrates how an efficient, albeit inefficient approach (subtraction), prevents recognition of simpler solutions.
  • Functional Fixedness: Inability to see beyond an object's typical use.
  • Duncker's candle problem: Participants fixated on the box's primary function (to hold the matches) and couldn't perceive alternate uses.
  • Scheerer's nine-dot problem: Individuals struggled to overcome mental rigidity, fixated on the box's primary function.

Insight and Hints

  • Hints can help or solve insight problems.
  • Whether true insight exists without hints is debated. Hints are essential in many scenarios.
  • Weisberg & Alba (1981): Many insight problems require hints.

Role of Past Experience

  • Past problem-solving experiences guide current approaches, often involving memory and restructuring (organizing past information).

Feelings of Knowing (FoK) & Feelings of Warmth (FoW)

  • FoK: Feeling familiar with a solution without recall.
  • Brown & McNeil (1966): Found FoK sometimes predicts answers when a word's initial letter is known. Insights problems aren't helped by feelings of knowing.
  • Metcalfe (1986): FoK is useful for general knowledge, not insight problems.
  • FoW: Indicates proximity to a solution.
  • Metcalfe & Wiebe (1987): FoW predicts progress in incremental, not insight based, problem-solving.

Deductive Reasoning (Syllogism)

  • Deductive reasoning: A logical argument with two premises and a conclusion.
  • Example: All cats are animals. All animals are living organisms. Therefore, all cats are living organisms.
  • Modus Ponens: If P, then Q. P → Q.
  • Modus Tollens: If P, then Q. Not Q → Not P.
  • Invalid syllogisms:
    • Affirmation of the consequence: If P, then Q. Q → P (Incorrect assumption)
    • Denial of the antecedent: If P, then Q. Not P → Not Q (Incorrect assumption)

Reasoning: Mental Models (Johnson-Laird, 1983)

  • Reasoning involves creating mental models to assess conclusions based on problem information.
  • Errors result from not considering all possible models; increased model complexity hinders reasoning accuracy.
  • Mental models represent possibilities; they do not include impossibly.

Reasoning: Inductive and Deductive

  • Reasoning employs induction and deduction.

Inductive Reasoning

  • Reasoning from specific observations to general conclusions; Observation → Pattern → Hypothesis → Theory

Deduction

  • Starts with a general rule and leads to a certain conclusion if the rule is true. Theory → Hypothesis → Observation → Confirmation

Reasoning Tasks

  • Wason task (2-4-6 task): Confirmation bias (prior beliefs) often leads to poor performance. Minimal improvement despite incentives.
  • Wason card selection task: People often choose cards that confirm, rather than falsify, the rule. Concrete examples and context improve performance (Wason & Shapiro, 1971).
  • Factors Influencing Reasoning:
    • Memory cues are relevant. If people remember cases that disconfirm a rule, they are more likely to falsify it (e.g., Florida's "drinking age" rule experiment, Griggs & Cox, 1982).
    • Pragmatic reasoning improves performance in familiar contexts. Performance improves with concrete examples, familiar contexts, and relevant rationale (e.g., permission-based scenarios like "receipt approval for $30+ purchases"). Cheng & Holyoak (1985) supported this by showing providing rationale improves reasoning. Experience without rationale also improves reasoning. Pragmatic reasoning is gained through being used to a situation, as well as right instruction.

Biases in Reasoning

  • Belief Bias: Accepting believable but invalid conclusions, overriding logical reasoning. This frequently happens with the first believable model presented.
  • Heuristics: Mental shortcuts for problem solving; results are efficient but not necessarily optimal.
  • Representative Heuristic (Kahneman & Tversky, 1972, 1973): Judging probability by comparing to stereotypes,
    • Engineering/Lawyer example (Kahneman & Tversky, 1973): Overlooking base rates for specific features. Participants were asked to guess the profession from a box of cards with brief character descriptions. The box contained 30 descriptions of engineers and 70 of lawyers. Findings: Participants ignore the base rate probabilities and base their judgement on whether the description sounded like a description of an engineer or a lawyer.
    • Conjunction Fallacy (Kahneman & Tversky, 1982): Linda problem: Thinking the probability of two events is higher than the probability of one event (e.g., bank teller and a feminist). More likely to happen with conjunctions than individual events
      • Example: Linda is 31, outspoken, and concerned about discrimination. Question: Is Linda more likely a bank teller or a bank teller and a feminist? Finding: 90% chose "feminist bank teller" (conjunction fallacy).
  • Gambler's Fallacy: Belief a random event's future likelihood depends on past outcomes.
  • Availability Heuristic: Quick decision making based on easily accessible information, potentially impacting risk assessment. This leads to overestimation of low-frequency events and underestimation of high frequency events.
    • Lichtenstein et al. (1978): Participants underestimated frequent causes of death (e.g., heart disease, cancer) and overestimated infrequent causes (e.g., accidents).
  • Base Rate Neglect: Ignoring base rates (general prevalence); over-focusing on specific details.
    • Tversky & Kahneman (1982): Taxi-cab study. Participants overestimated the likelihood of blue taxis based on identification accuracy, despite the base rate difference.
    • Casecells et. al. (1978): Medical diagnosis study. Medical students ignored the low disease prevalence (1/1000), focusing on the false +ive rate instead; better with frequencies than probabilities (Cosmides & Tooby, 1996).

Normative Reasoning

  • Decision-making involves evaluating potential outcomes and probable information. e.g., What might happen?

Human Reasoning

  • Human reasoning is biased due to heuristics.
  • Heuristics are cognitive shortcuts leading to sufficient, not necessarily optimal, results.
