WebWhen the S+ and S– were close together, the peak of responding was shifted on initial generalization tests. Generalization gradients along the orthogonal vertical dimension were approximately exponential in shape. This is the first demonstration of generalization and peak shift in the spatial domain. WebIn behavioral psychology, stimulus control is a phenomenon that occurs when an organism behaves in one way in the presence of a given stimulus and another way in its absence. …

WebAbstract “Peak shift” is a behavioral response bias arising from discrimination learning in which animals display a directional, but limited, preference for or avoidance of unusual stimuli. Its hypothesized evolutionary relevance has been primarily in the realm of aposematic coloration and limited sexual dimorphism. Here, we develop a novel … WebNov 20, 2009 · Peak shift occurs in generalization tests following intradimensional discrimination training as a displacement of peak responding away from the S+ (a stimulus signaling availability of reinforcement) in a direction opposite the S- (a stimulus signaling lack of reinforcement). chariti malformation
