Anger perception tasks involve observing and interpreting subjects’ performance when they are faced with uncertainty and risk. After an initial task, subjects were randomly given one of three types of training to help improve their performance. Base rate training aimed to improve response bias by informing the participant to attend to how common angry faces appear in the task. Payoff training aimed to improve response bias by having participants reevaluate just how beneficial or costly a correct or incorrect judgement was. Similarity training aimed to improve category discrimination by directing participants to pay attention to specific facial features that can help to distinguish angry versus not angry faces. Subjects’ performance and the type of training were analyzed to identify the most effective form of training. Individuals presented with payoff training saw an overall improvement in performance with the signal-detection task, indicating that this form of feedback proved to be advantageous.
Results
We found a significant effect of training condition on change in response bias, F (2,49)=3.5, P
