1. In order to determine the degree of synchrony of binocular activation required for the development of binocularity we reared 11 kittens with rapidly alternating monocular occlusion. Alternating occlusion was achieved with microprocessor-controlled electrooptic solid-state shutters, which were fitted to individually moulded goggles. The intervals of(More)
The concept of the epidemiology of Cryptococcus neoformans as the causative agent of cryptococcosis and as a basidiomycetous yeast is based on the fact that bird manure has been until now its only known habitat but not plant material which likewise harbours various nonpathogenic Cryptococcus species. It could be shown that the possible influence of(More)
Psychophysical measurements were carried out with a microcomputer-controlled matrix of 32 X 32 light emitting diodes to determine temporal parameters of figure-ground separation processes. The task was to detect a figure that was dispersed in time. Between each two figure elements n noise elements were interspersed. The results of these experiments indicate(More)
Amblyopic subjects were tested on different visual tasks which required temporal integration of successively presented stimuli: a figure had to be detected whose components were displayed successively and hidden in spatio-temporal noise. The time interval T over which the figure elements were dispersed was varied and the longest T value still compatible(More)
for their efforts in collecting these data, and we would like to thank the participants and their families for taking part in this project. Two cross-modal naming experiments examined the role of working memory in processing sentences and discourses of various lengths. In Experiment 1, 10 memory impaired patients with probable Alzheimer's disease (AD) and(More)
This research investigated the effects of prior knowledge on learning in psychologically-plausible connectionist networks. This issue was examined with respect to the benchmark orthography-to-phonology mapping task (Sejnowski & Rosenberg, 1986; Seidenberg & McClelland, 1989). Learning about the correspondences between orthography and phonology is a critical(More)
Normal adult cats show a 35% increase in pupil diameter when one eye is illuminated and the other occluded, rather than when both eyes are illuminated. Young kittens show significantly less binocular luminance summation than adult cats (14%). Since these kittens also show a significantly reduced pupillary response to luminance decrements, the postnatal(More)
