Abstract : This report describes the progress made during the first year of an equipment grant which has provided a common computing environment for four laboratories conducting research in perception and cognition at the University of Minnesota. Research in the Cognitive Psychology Laboratory has shown that learning a procedural skill can occur in the absence of any declarative learning. Progress has also been made toward developing a computer simulation of this process. In the Visual Psychophysics Laboratory several image-enhancement algorithms have been developed as well as a psychophysical procedure for evaluating those algorithms. Research in the Auditory Psychophysics Laboratory has concentrated on developing a model of the detection and recognition of complex auditory signals by human observers. A subset of the model has been implemented as a computer simulation and several experiments have been completed to guide its future direction. In the Psycholinguistics Laboratory a computer model of text comprehension and recall has been constructed. Several experiments have been completed that confirm assumptions built into the model and show a good correspondence between its performance and that of human subjects.
