| Abstract |
The deteriorations in perception, in temporal, visual and tactile resolution tasks, observed in men during simulated hyperbaric dives in a caisson (3 days' saturation at 300m) were analysed. The experimental procedure was based on a constant stimulus method (presentation of sets of 6 stimuli, in random order), though data were analysed according to the SDT model and 2 indices were extracted from psychophysical curves: curve slope (as sensory sensitivity); and mean of the curve (as response bias). Results show that these 2 indices vary independently; the sensory index is related to dive profile; alterations of bias response seem to express individual factors. |
