Peak shift and rules in human generalization
WebFigure 1. Example of typical generalization gradients following single cue and differential Pavlovian conditioning. CS (S in instrumental conditioning) is the conditioned stimulus paired with an outcome, and CS (S in instrumental conditioning) is the conditioned stimulus not paired with an outcome. See the online article for the color version of this figure. - … WebDuring postdiscrimination generalization testing, the peak of the generalization gradient is displaced from the S to another stimulus that is farther from the S than from the S (e.g., …

WebOur model also implies that combination rules do not vary categorically. Instead, there is a gradual shift from one combination rule to the other— depending on changes in the continuously valued parameter r—and any of the intermediate rules may describe the generalization data for a particular set of stimulus dimensions. WebPeak shift describes the situa-tion in which the peak of the generalization gradient shifts from the location of the S+ in the direction away from the S-. This effect is well accounted …

WebPeak shift was observed in Experiment 1, in which generalization tests immediately followed training, and in Experiment 2, in which the tests were delayed by 24 h. These findings further support the universality of generalization processes across species, modalities, and levels of stimulus complexity. flashback memoriesWebOther theories have been proposed, including the idea that the peak shift is an example of relational control; that is, the discrimination was perceived as a choice between the “greener” of two stimuli, and when a still greener stimulus was offered the pigeons responded even more rapidly to that than to the originally reinforced stimulus. flashback memories psychologyWebOct 8, 2011 · In Hanson’s classic peak shift demonstrations with pigeons, more similar S+ and S– discrimination wavelengths led to a larger shift in generalization away from the S–.
