Dynamics of Visual Representation, Attention, Encoding, and Retrieval Processes

摘要

This is the Final Technical Report of work supported by a grant entitled 'Thedynamics of visual representation: Attention, encoding, and retrieval processes'. After a section describing the objectives of the work, the report provides a synopsis of the principal accomplishments, in five categories: (1) Investigation of the relation between location-probe and probed-reciting paradigms, to test whether the transformations that underlie performance changes with probe delay in the two paradigms are the same or different; (2) Investigation of the transformation associated with the location-probe paradigm; (3) Extensive work with the probed-reciting paradigm at zero probe delay, manipulating the legibility of the displayed characters as another approach to studying the transformation required for response; (4) Application of variants of a traditional visual search paradigm to investigate effects of properties of the early representation on the order of search, again by manipulating legibility; (5) Development of new tests of stage models of mental operations.
