Cognitive style in adults: task alternatives, task strategy, and time estimation

P C Kendall, J F Hooke, R Rymer

    Journal of Personality Assessment
    |April 1, 1980
    PubMed
    Summary

    Cognitively impulsive adults show longer decision times with more task options, unlike reflective adults. This suggests impulsivity may stem from response inhibition deficits, potentially treatable with cognitive-behavioral strategies.

    Area of Science:

    • Cognitive Psychology
    • Neuroscience
    • Behavioral Science

    Background:

    • Cognitive impulsivity is linked to decision-making differences.
    • Understanding decision time variations is crucial for cognitive research.

    Purpose of the Study:

    • To investigate how task complexity affects decision times in impulsive versus reflective individuals.
    • To explore behavioral differences, including verbalization and motivation, between these groups.

    Main Methods:

    • A match-to-sample task with varying numbers of alternatives was used.
    • Decision times and "thinking out loud" verbalizations were recorded.
    • Self-reported motivation and time estimation accuracy were assessed.

    Main Results:

    Related Experiment Videos

    • Increased task alternatives prolonged decision times for reflective adults only.
    • Impulsive adults exhibited less verbal behavior, higher speed motivation, and time underestimation.
    • A latency-related response inhibition deficit was suggested for impulsive adults.

    Conclusions:

    • Cognitive impulsivity is associated with distinct decision-making patterns and potential response inhibition deficits.
    • Findings support the consideration of cognitive-behavioral interventions for impulsivity.
