The question of whether sudden increases in the amplitude of pure-tone components would perceptually isolate them from a more complex spectrum was investigated in two experiments. In Experiment 1, a 3.5-sec noise was played as a masker. During the noise, two pure-tone components of different frequencies appeared in succession. Subjects were asked to judge whether the pitch sequence went up or down. The rise time of these components had only a small and inconsistent effect on discrimination. In Experiment 2, the 3.5-sec background signal was a complex tone. The amplitudes of two of its components were incremented in succession. Again, subjects judged whether the pitch pattern went up or down. This time there was a sizable, monotonic effect of the rise time of the increments, with more rapid increments leading to better discrimination. The difference between the two results is interpreted in terms of the auditory system’s response to changing and unchanging signals and the role of its “sudden-change” responses in attracting perceptual processing to certain spectral regions.  相似文献

An experiment was conducted to relate individual components of the event-related brain potential to specific stages of information processing in a two-choice reaction time (RT) task in a group of undergraduate students. Specifically, the latency of the P300 component and the lateralized readiness potential (LRP) were studied as a function of variations in stimulus degradation and response complexity. It was hypothesized that degrading the stimulus would delay the P300 and LRP to the same extent as RT, and that increasing response complexity would affect RT but not P300 latency. The extant literature did not permit any hypothesis regarding the effect of response complexity on LRP latency. The two task variables were found to have additive effects on RT. As predicted, variations in stimulus degradation influenced the latencies of both components, whereas alterations in response complexity had no effect on P300 latency. A significant new finding was that the onset latency of the LRP remained unchanged across levels of response complexity. The overall pattern of results supports the notion of temporal selectivity of stage manipulations that is derived from discrete stage models of human information processing. Furthermore, these results refine the functional interpretation of the LRP by indicating that within the conceptual framework of a stage model the processes this component indexes succeed the start of response choice but precede the start of motor programming.  相似文献

Rational-emotive therapy (RET) can be particularly applied to individuals with serious love problems, such as people possessed by super-romantic love, limerents who are mired in obsessive-compulsive feelings, insensately jealous and possessive lovers, people who needlessly interfere with their encountering suitable partners, and those who suffer anguish and depression when they lose love. It also has important things to teach about keeping alive and enhancing normal love feelings. This paper outlines the RET theory of love and applies it to various amative difficulties.This article is to appear as a chapter inClinical applications of Rational-Emotive Therapy, edited by Albert Ellis and Michael Bernard, New York: Plenum, 1985.  相似文献

Earlier studies involving the lateralization of arithmetic abilities have provided evidence for both right and left hemisphere superiorities. It is argued here that part of this inconsistency could be due to the complexity of the arithmetic computations which have been examined. The present studies examined a subprocess shown to be involved in more complex tasks, such as subtraction. The subprocess is the identification of which of two numbers is greater, and was tested by the flashing of a pair of digits to either the left or right visual field. Errors, reaction-times to make a decision, and examination of hand × visual field interactions all indicated that this subprocess is mediated by the right hemisphere. Correlational analysis was used to identify the operations underlying the observed lateralization of this ability. This analysis indicated that an operation indexed by the spatial order in which the digits were presented was effective in the right hemisphere but not the left hemisphere. Speculations on the nature of these operations were presented.  相似文献

An Ames (1951, Psychological Monographs, 65(1, Whole No. 324)) static trapezoidal window, under monocular view, was used to test young infants' responsiveness to pictorial depth. When adults view this display monocularly with the smaller side of the window rotated toward them, they report that the orientation of the display becomes ambiguous: When the head is moved, the window may appear to be in the fronto-parallel plane or either side may appear closer. The 7-month-olds we tested appeared to experience a similar ambiguity; they reached to the near side of the rotated trapezoidal window with significantly less consistency or directedness than infants in a control group tested with a rotated object that lacked pictorial depth information. When 5-month-olds were tested, however, they reached with equal consistency to the closer side of the trapezoidal window and of the control display, apparently uninfluenced by the pictorial depth information available in the trapezoidal window. Thus, sensitivity to the pictorial information for depth that is present in the trapezoidal window appears to develop after the age of 22 weeks.  相似文献

Sex-role research has been hampered by a lack of valid and reliable research tools to measure the construct being studied. This article describes the development of a research scale (ISRO) to measure women's sex-role orientation. This 16-item questionnaire has been shown to be internally consistent and to have fairly high temporal stability over 30 days. The high sensitivity (96.2%) and specificity (95.5%) suggest that it differentiates feminist from traditional women. Three factors assess attitudinal domains of conflict between family responsibilities and having a career; male/female division of household responsibilities; and women's work roles outside the home. Education appears to be the strongest predictor of ISRO scores.This study was supported in part by a grant from the American Nurses Foundation.  相似文献

Conclusion Therapists are human-and, believe it or not, fallible humans. Ideally, they are supremely well infored, highly confident, minimally disturbed, extremely ethical and rarely under- or overinvolved with their clients/Actually, they are hardly ideal. If you, as a therapist, find yourself seriously blocked in your work, look for the same kind of irrational beliefs, inappropriate feelings, and dysfunctional behaviors that you would investigate in your underachieving clints. When you ferret out the absolutistic philosophies and perfectionist demads that seem to underlie your difficulties, ask yoursell—yes,strongly ask yourself—these trenchant questions: (a) Why do Ihave to be an indubitably great and unconditionally lowed therapist?; (b) Where is it written that my clientsmust follow my teachings and absolutelyshould do what I advise?; (c) Where is the evidence that therapymust be easy and that Ihave to enjoy every minute of it?If you persist in asking important questions like these and insist on thinking them through to what are scientific and logical answers, you may still never become the most accomplished and sanest therapist in the world. But I wager that you will tend to be happier and more effective than many other therapists I could—but charitably will not—name. Try it and see!This article is adapted from an invited address presented at the 91 st Annual Convention of the American Psychological Association at Anaheim, Calif., August 1983.  相似文献
