(B ) Schema retrieval: left, % of correct responses; middle, average reaction time (s); right, % of high-confident ratings (i.e. "sure -responses).
(A ) Data represents the % of correct responses, (B ) the average reaction time (s), and (C ) the % of high-confident ratings (i.e. "sure -responses).
Confidence ratings: 1 - very uncertain, 2 - uncertain, 3 - moderately confident, 4 - confident, 5 - very confident.
Thus, each item (i.e., question) included four possible answers, at least four possible scientific reasons, and confidence ratings such that students could separately estimate how confident they were about their answers and their reasons.
In Kenya, prior to the training the facilitators were quite confident in a few of the specified tasks, but their confidence ratings for seven items were below 4.0.
To examine different types of errors in relation to brain activation, we divided total responses into two categories based on the confidence ratings; 'confident' for the ratings 1 and 2 and 'not-confident' for the ratings 4 and 5.
Confidence ratings were solicited on a 4-point response scale ranging from 1 = very confident to 4 = not at all confident.
Thus, the groups' confidence ratings mirrored the patterns observed in their task performance, with the patients being more confident about their correct responses, whereas the controls were more confident about their erroneous (BE-influenced) responses.
Dyads were more confident in their search performance than individuals t 36.438) = 1.75, p = 0.04) though unlike the individuals in Experiment 1a, confidence ratings for the dyads failed to predict accuracy (β1 = 0.043, F 1,15) = 2.291, p = 0.151, adj R2 = 0.07).
