Summary

Researchers investigated how confidence ratings change between yes-no and forced-choice tasks. Findings suggest neither normative nor other models fully explain confidence shifts, leaving linear and multiplicative models as possibilities.

Area of Science:

  • Cognitive Psychology
  • Decision Making
  • Psychometrics

Background:

  • Yes-no and forced-choice tasks are frequently used in psychological research.
  • The relationship between confidence judgments in these two distinct task formats remains empirically underexplored.

Purpose of the Study:

  • To investigate the empirical relationship between confidence judgments in yes-no and forced-choice tasks.
  • To determine how confidence in general knowledge statements changes when transitioning between these task formats.

Main Methods:

  • Two experiments were conducted using general knowledge statements.
  • Participants provided confidence ratings for statements in a yes-no format.
  • Confidence was re-assessed when statements were presented in a forced-choice format (one true, one false).

Main Results:

  • The study examined changes in confidence ratings between the yes-no and forced-choice tasks.
  • Two tested models, including a normative model, were invalidated as descriptive accounts of the observed data.
  • Both a linear model and a multiplicative model emerged as viable explanations for the confidence shifts.

Conclusions:

  • Existing models do not fully capture the dynamics of confidence reporting across different task types.
  • Further research is needed to refine models explaining confidence judgments in psychological tasks.
