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 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 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 کاملIntegrality/separability of stimulus dimensions and multidimensional generalization in pigeons.
The authors present a quantitative framework for interpreting the results of multidimensional stimulus generalization experiments in animals using concepts derived from the geometrical approach to human cognition. The authors apply the model to the analysis of stimulus generalization data obtained from pigeons trained with different sets of stimuli varying along two orthogonal dimensions. Separ...
متن کاملSmall-scale spatial cognition in pigeons.
Roberts and Van Veldhuizen's [Roberts, W.A., Van Veldhuizen, N., 1985. Spatial memory in pigeons on the radial maze. J. Exp. Psychol.: Anim. Behav. Proc. 11, 241-260] study on pigeons in the radial maze sparked research on landmark use by pigeons in lab-based tasks as well as variants of the radial-maze task. Pigeons perform well on open-field versions of the radial maze, with feeders scattered...
