Spatial Peak Shift and Generalization in Pigeons
How pigeons generalize across spatial locations was examined in the 4 experiments reported in this article. During training, a square was presented at a fixed height at 1 of 2 horizontal locations on a monitor screen. One location (S +) signaled reward, whereas the other one (S ) signaled no reward. The birds were then tested occasionally with a range of locations. After training with S+ only, ...
متن کاملTemporal generalization and peak shift in humans.
Three experiments investigated temporal generalization in humans. In Experiment 1, a peak shift effect was produced when participants were given intradimensional discrimination training. In Experiment 2, after training with a standard S+ and generalization testing with an asymmetrical series of durations, generalization gradients moved toward the prevailing adaptation level. In Experiment 3, ge...
متن کاملSpatial generalization and peak shift in humans
Using a computer betting game, five experiments tested university students on spatial generalization and peak shift. On each trial, one location was marked and the subject was invited to bet 0–4 points. At the winning location (S+), bets won four times the points betted. At nearby losing locations (S)s), points betted were lost. Generalization gradients were exponential in shape, supporting She...
متن کاملEffects of Stimulus Contrast On
The effect of stimulus contrast changes on the binocular visual evoked response (VER) was investigated using pattern reversal VER, dichoptic stimulation, and Fast Fourier Transform. When the stimulus contrast was changed binocularly, the monocular components increased as the contrast increased. The binocular component first appeared at the level of 10% contrast; its magnitude was stable under a...
متن کاملStimulus Contrast and Retinogeniculate Signal Processing
Neuronal signals conveying luminance contrast play a key role in nearly all aspects of perception, including depth perception, texture discrimination, and motion perception. Although much is known about the retinal mechanisms responsible for encoding contrast information, relatively little is known about the relationship between stimulus contrast and the processing of neuronal signals between v...
