Confidence and decision speed in the revision of opinion

摘要: Abstract The present experiment examined decision speed, measured without the subject's knowledge, and sequential confidence revision in a two-choice task. Subjects were presented with ten sequences of 20 events from one two data-generating devices. Before each event was presented, subjects predicted outcome, after they decided which devices being used gave judgment this decision. Following that disconfirmed their favored hypothesis, demonstrated marked resistance to decreasing level (Inertia Effect). Two possible explanations Inertia Effect postulated predictions compared data. A commitment hypothesis assumed unwilling reduce stated following decision, while pattern-effect based upon hypothetical expectancies, reflected his predictions. Both hypotheses partially supported; function subjects' accompanied by decrease speed.
