Two groups of participants were trained with 2 stimulus compounds (XY and XZ). In Group TD (true discrimination), compound XY was always followed by the outcome, whereas compound XZ was never followed by it. In Group PD (pseudodiscrimination) the presentation of each compound was followed by the outcome in half of the trials. Experiment 1 found that… CONTINUE READING
