The present study assessed whether training-related improvements are stimuli specific, generalize across changes in the locations of objects, generalize across tasks, and are dependent on the type of training. Participants were trained with feedback on a \"flicker\" change detection task where the pre- and post-change scenes were alternated until a response was made. In Experiment 1, participants were trained on a location-change-detection task or completed an unrelated visual task on Day 1. Trained participants heard one set of stimuli in the auditory scenes. On Day 2, all participants were tested on the flicker task during which EEGs were recorded. Participants heard sounds from Day 1 or \"novel\" sounds they had not heard before. Participants who were trained on the change-detection task performed better than control participants. Trained participants did not perform better when hearing sounds they were trained with, but they did perform better on the generalization test than the control participants. There were no ERP differences between control and trained participants; all participants showed higher P1, N1, and P2 and lower P3a and P3b amplitudes for correct change trials. In Experiment 2, participants were divided into three groups: Space-trained, ID-trained, and Space/ID-trained. Each group received training on a flicker task with only one type of change in scene composition on Day 1. On Day 2, all participants were tested on a one-shot task with no change, ID-change, and Space-change trials. Results showed that training type did not impact performance in the one-shot task or ERP component amplitudes for the different types of change trials during testing. However, differences were present in ERP amplitudes during Scene 1 depending on the types of errors participants made. P3b amplitudes during Scene 2 were higher for wrong change trials than change-deaf trials for all participants. Overall, improvements from training were not specific to sound, generalizing to novel sounds. The different training regimens did not produce prominent ERP differences for the different types of trials and trained subjects did not show different ERP patterns from controls. Training improves performance in an auditory change detection task, but the changes are not specific to familiar sounds, and do not generalize from one type of task to another.","**To request an accessible version of the file(s) associated with this item, contact library@buffalo.edu.
