The degree of confidence under uncertainty can be described by two aspects: cognitive and behavioral. The present study was designed to examine the relationship between cognition and behavior by measuring confidence scores and conforming responses to cue information in two-choice prediction situation. Probability of cue information being positive was 1.0, .75, .5, .25, and 0. The main results were as follows: (a) Both confidence scores and conforming responses depended on cue information, but while asymptotic confidence scores approximated the probability of positive information under any condition, rates of conforming responses exceeded the probability of positive information except under a 100% condition, (b) in the early stage of trials the pattern of conforming responses markedly differed from that of confidence scores, and (c) confidence scores changed sensitively according to accuracy of cue information. These findings suggest that confidence and behavior result from different sources respectively, and that many biases appear particularly in behavioral aspect.
