Reference dependence refers to the reduced value of a reward that is less than expected, or the added value of a reward that is greater than expected. There is evidence that when pigeons are offered an alternative that has 1 pellet versus an alternative that has 2 pellets, but one of the two pellets offered will be removed, the pigeons prefer the originally presented 1 pellet (loss aversion). In the present research, we tested for the opposite effect (gain attraction). In Experiments 1 and 2, pigeons could choose between 2 pellets, each one on a distinctive background. If they chose the optimal alternative, they received a second pellet. In Experiment 2, the second pellet obtained was the one not initially chosen (a task sometimes referred to as the ephemeral reward task). Pigeons learned to choose optimally in both experiments. In Experiment 3, we tested the pigeons for reference dependence. Pigeons were given an alternative that offered them one pellet or two pellets, if they chose the one-pellet alternative, they received an additional pellet, and if they chose the two-pellet alternative, they received the two pellets. In keeping with the reference dependence hypothesis, the pigeons preferred the 1-pellet alternative that gave them an extra pellet. These effects are related to similar findings with humans, including the endowment effect.

The recent paper by Schraw ( Measures of feeling-of-knowing accuracy: a new look at an old problem , Applied Cognitive Psychology, 1995, 9, 321—332) is flawed by several inaccuracies and by Schraw's failure to distinguish between two fundamentally different aspects of the accuracy of metacognitive predictions: (1) calibration (aka absolute accuracy, defined in terms of whether the predicted value assigned to a single item is followed by the occurrence of that value on the criterion test), and (2) resolution (aka relative accuracy, defined in terms of whether the predicted performance on one item relative to another item is followed by the occurrence of that ordering of the two items on the criterion test). Because of these (and other) problems, his recommendations seem misleading and counterproductive.  相似文献

This article reports on some clinical applications in the 9 to 30 month age range of a new structured paradigm. The Infant Clinical Assessment Procedure (ICAP) is not a test, but an assessment technique. It is particularly aimed at the evaluation and ongoing monitoring of problems in the emotional development of infants. Its eight episodes represent a wide array of effective, social, and cognitive stimuli. The primary focus of these episodes is on the infant, with the exception of the mother-infant task that specifically gauges the mother-infant ralationship. It is suggested through case vignettes that the ICAP may be useful for the documentation of the efficacy of treatment.  相似文献

Most psychologists believe that Structuralism, the psychology of E. B. Titchener, was a faithful copy of Wilhelm Wundt's original psychology. This belief is fostered by textbooks for history and systems and introductory psychology courses. The present paper argues that this belief is false. Titchener rejected many of Wundt's goals and concepts, and should be viewed as a traditional British associationist and positivist rather than as a follower of Wundt. Similarities of Wundt's system and Titchener's system to current psychological thinking are noted.  相似文献
