Abstract : We have worked on a number of different projects relating to visual perception and memory for features and objects, exploring the processing that converts visual sensory data to representations of objects and events. An important focus has been to define the role played by attention in this processing and in the - memory representations which result. I divide this report into four main sections: One deals with studies of relatively early visual processing of features; another with the role of attention in feature integration; another major project explores the effects of the initial perception of novel objects on their reperception, either immediately, after a single presentation, or after multiple trials or long delays, using negative priming tasks to explore the memory traces formed for novel objects, both with and without attention; the final section explores the notion of object tokens in the context of perceptual learning and priming in visual search automatization.
