Event Abstract Back to Event Allocation of Attention during Tasks Involving Discriminations of Rotated Stimuli Jordan Searle1* and Jeff Hamm1 1 University of Auckland, School of Psychology, New Zealand Participants were assigned to one of three tasks, namely to determine if a dot was located at the top or bottom pole of a rotated object, to determine if a rotated object would face to the left or right if imagined at the upright, or to determine if a rotated letter was in its mirrored or normal version. EEG was employed to investigate how attention is initially allocated to the stimuli in each task. Directing attention to task-relevant lateralized visual information is known to produce an N2pc component. For decisions regarding the location of a dot at the top or bottom pole of a rotated object, the analysis of ERPs to lateralized locations of the dots revealed the presence of an early posterior contralateral negativity. Further analysis of ERPs for this task, this time to lateralized locations of the fronts of the objects, revealed the presence of an N2pc component. For decisions regarding the direction in which a rotated object was facing, the analysis of ERPs to lateralized locations of the fronts of objects also revealed the presence of an N2pc component. Finally, for decisions regarding whether rotated letters were mirrored or normal, the analyses of ERPs to lateralized locations of the tops of letters or to lateralized locations of the letters' distinguishing features revealed little evidence to suggest the presence of lateralized attention. These results indicate that early visual processing is adapted to the needs of the decision that is required of the task.
