Webexcept E showed a peak shift, peaking at -22.5 deg rather than at 0 deg. All of the birds, including E, showed an "area shift" (Terrace, 1966). Each bird made more responses during the generalization test to line tilts to the left (negative) than to the right (positive) of the 0 deg line. These data are summarized in Table 2. 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 …

Web2 days ago · Including happiness in economics has opened up an entirely new avenue of research to explore the relationship between happiness and money. Andrew Clark (2024) illustrates the variability in the term happiness economics with the following examples: Happiness can be a predictor variable, influencing our decisions and behaviors. WebUnder these conditions, a “peak shift” effect is often observed, where the highest point of responding at test is not at the original CS+ value but at a value further along the dimension in the direction away from CS– (e.g., Ellis, 1970; Hanson, 1959). Spence (1937) attributed peak shift to the interaction of gradients of excitation and Webpeak shift. 1. a phenomenon in stimulus generalization that occurs after discrimination training involving two stimuli along a common dimension (e.g., brightness).
