In the typical induction of the orientation-contingent color aftereffect (CCAE), the stimuli are composed of elements that differ in both color and luminance. Three experiments are reported that show that chromatic contrast between stimulus elements is insufficient for the induction of the orientation-CCAE and that luminance contrast is necessary. These experiments expand on previous research concerned with the role of luminance contrast in the induction of orientation-CCAEs by eliminating alternative explanations. 相似文献

Attention/likelihood theory has been used to explain the mirror effect in recognition memory. The theory also predicts that any manipulation that affects the recognition of old items will also affect recognition of the new items—more specifically, that all the underlying distributions will move and that they will move symmetrically on the decision axis. In five experiments, we tested this prediction. The first two experiments used encoding tasks during study to change recognition performance for high- and low-frequency words. The results show symmetrical dispersion of the underlying distributions. The final three experiments used repetition to increase recognition performance. Repetition produced a symmetrical pattern of movement that was different from that produced by encoding task. This pattern is, however, also covered by attention/likelihood theory. A further extension of the theory was used to predict response times. 相似文献

Receiver-operating characteristics (ROCs) were examined in three recognition memory experiments. ROCs for item information (i.e., was this word presented?) were found to be curvilinear. However, ROCs for associative information (i.e., were these two words presented together?) were found to be linear. The results are in agreement with the predictions of a dual-process model that assumes that recognition judgments are -based on familiarity and recollection. Familiarity reflects the assessment of a continuous strength dimension and is well described as a signal detection process, whereas recollection reflects the retrieval of qualitative information about the study episode and behaves like a discrete threshold process. The results showed that memory judgments about items relied on a combination of recollection and familiarity, but that judgments about associations relied primarily on recollection. Further examination of the associative ROCs suggested that subjects were able to recollect that old pairs of items were in the study list, and, under some conditions, that new pairs were not in the study list. 相似文献

The limited capacity theory assumes that working memory (WM) has limited capacity to process information and, at the same time, to store other pieces of information, necessary for further processing. Quick processing of data is supposed to be the only way to solve the task without the risk of losing vital pieces of information. We predicted, then, that the correlation between mental speed, measured by reaction time (RT), and the intelligence quotient (IQ) should not appear in the case of persons who possess a relatively capacious WM store, or who show increased retention capability of their WM store. Such persons do not need to be fast, whereas, for people who show poorer indices of capacity or retention capability of WM, mental speed is the only way to tackle a complex and difficult intellectual task. As predicted, the RT/IQ correlation appeared much stronger in the group of subjects characterized by lower retention capability and capacity of WM. 相似文献

Nick Huggett and Robert Weingard (1994) have recently proposed a novel approach to interpreting field theories in physics, one which makes central use of the fact that a field generally has an infinite number of degrees of freedom in any finite region of space it occupies. Their characterization, they argue, (i) reproduces our intuitive categorizations of fields in the classical domain and thereby (ii) provides a basis for arguing that the quantum field is a field. Furthermore, (iii) it accomplishes these tasks better than does a well-known rival approach due to Paul Teller (1990, 1995). This paper contends that all three of these claims are mistaken, and suggests that Huggett and Weingard have not shown how counting degrees of freedom provides any insight into the interpretation or the formal properties of field theories in physics. 相似文献

Human intuition is a rich and useful guide to uncertain events in the environment but suffers from probabilistic incoherence in the technical sense. Developing methods for extracting a coherent body of judgement that is maximally consistent with a person's intuition is a challenging task for cognitive psychology, and also relevant to the construction of artificial expert systems. The present article motivates this problem, and outlines one approach to it. 相似文献

ABSTRACT Two experiments investigated claims for the efficacy of self-deceptive coping (e.g., Sackeim, 1983, 1988). In Study I the performance of self-deceivers on solvable anagrams was found to he remarkably poor relative to that of non-self-deceivers after both groups were exposed to unsolvable problems. The starkly unambiguous failure experience may have precluded self-deception. Therefore, in Study 2 participants were exposed to unsolvable problems either with or without an excuse. Self-deceivers who encountered failure with an excuse subsequently performed much better on the solvable tasks than those without an excuse. These findings suggest that the use of self-deception following threat is constrained by the availability of contextual ambiguity (e.g., excuses). The effect of the excuse was not related to participants' mood or attributions for performance. 相似文献

Two experiments are reported which attempt to disentangle the relative contribution of intentional and automatic forms of retrieval to instance-based categorization. A financial decision-making task was used in which subjects had to decide whether a bank would approve loans for a series of applicants. Experiment 1 found that categorization was sensitive to instance-specific knowledge, even when subjects had practiced using a simple rule. L. L. Jacoby’s (1991) process-dissociation procedure was adapted for use in Experiment 2 to infer the relative contribution of intentional and automatic retrieval processes to categorization decisions. The results provided (1) strong evidence that intentional retrieval processes influence categorization, and (2) some preliminary evidence suggesting that automatic retrieval processes may also contribute to categorization decisions. 相似文献

This essay reports on phenomenological research conducted with people who describe having been harassed, having been accused of harassment, and/or having mediated or adjudicated harassment disputes. The authors review recent legal conceptions of sexual harassment and articulate a methodology for analyzing individual narrative accounts. The analysis of six selected interviews (three alleged harassers and three declared harassees) depicts how, through discourse with others, persons in ambiguous cases of harassment come to perceive themselves as harassers or harasseesgradually, how intention is inferred from conductcontingently, and how perceptions and expressions are often reified as certainties in the effort to secure some sense of justiceinstitutionally.Many people have been involved with this project since its inception, and most wish to remain anonymous. We would like to thank all participants, colleagues, students, and critics for their contributions and expressions of interest. We would especially like to acknowledge Thomas Pace and Richard Lanigan for their teaching, friendship and support, and Frances Chaput Waksler for her helpful comments. An earlier version of this paper was presented to The Society for Phenomenology and the Human Sciences, Boston MA, USA, October 1992. 相似文献
