Q

Cox and Griggs (Wason selection task) Study (cognitive)

Procedure

A
  • approx 140 undergrad psych students at the uni of florida
  • Participants were randomly allocated to one of six groups in order to counterbalance the experiment.
  • Each group was given a workbook with three problems. Each group had a different order.
  • For each of the following statements, they were asked which cards they would have to turn over in order to prove if the following statement is true.
    • Abstract Task: If a card has an A on one side, then it has a 3 on the other side
      • Cards: A, B, 2, 3
    • Intermediate Task: If a person is wearing blue, then the person must be over 19 years old.
      • Cards: Wearing blue, wearing green, 22 years old, 16 years old
    • Memory cueing task: If a person is drinking beer, then that person must be over 18 years old
      • Cards: Drinking beer, drinking Coke, 22 years old, 16 years old

Q

Cox and Griggs (Wason selection task) Study (cognitive)

Findings

A
  • Abstract task: Less than 5% solved the task correctly. Often just chose cards that confirmed the rule (showing confirmation bias).
  • Intermediate task: Approx 40% solved the task correctly.
  • Memory cueing task: Approx 60% solved the task correctly
  • Order effects also influenced accuracy
  • Supports hypothesis that people tend to use System 1 first to solve problems (rely on intuition rather than problem solving)
  • Supports the theory that the more abstract and less relevant the task, the more likely that cognitive biases would be used to solve the problem (resulting in less accuracy)
