Table 1.

Mean (and standard deviations) of the number of “yes” responses (hits in the case of pictures or false alarms otherwise), signal detection sensitivity (d?) scores, response bias (c) and affective ratings, for each trial type (hit rates for Experiment 3 are based on 18 cases rather than 36)
