Event-related brain potentials (ERPs) were recorded while subjects silently read several prose passages, presented one word at a time. Semantic anomalies and various grammatical errors had been inserted unpredictably at different serial positions within some of the sentences. The semantically inappropriate words elicited a large N400 component in the ERP, whereas the grammatical errors were associated with smaller and less consistent components that had scalp distributions different from that of the N400. This result adds to the evidence that the N400 wave is more closely related to semantic than to grammatical processing. Additional analyses revealed that different ERP configurations were elicited by open-class (“content”) and closed-class (“function”) words in these prose passages. 相似文献

Substantial differences exist across ethnic groups and sexes in generational changes in status among groups residing in Hawaii. Despite these generational differences across groups, age differences in personality are remarkably consistent across sexes and racial/ethnic groups, and the few Sex x Age, Ethnicity x Age or Sex x Ethnicity x Age interactions account for little variance in scores. It is concluded that age/generational differences in personality factor scores in these populations result from age and not, to any major degree, from cohort effects. 相似文献

A process analysis of group development forms the basis of a methodology for identifying group phase boundaries and describing moment-to-moment process in psychotherapy groups. This paper presents the general rationale for identifying variables, the statistical technique for producing graphs and the first of three variables used in the process analysis. The focus is on phases two and three as defined by Beck's theory of group development. The first variable tracks the members' responses toward the Scapegoat Leader in terms of supportiveness, criticism or hostility. Results on two groups show a clear shift in responses from negative to supportive as the group moves from phase two to phase three. 相似文献

Digital music synthesizers represent audio signals in the form of binary coded numbers. These binary coded numbers can be manipulated by the operator, thereby altering the audio signal in a variety of ways. The present article describes how these capabilities can be used to produce perfectly aligned dichotic tapes in which the stimulus items are matched on all extraneous (timbre, amplitude, duration) factors. 相似文献

The effects of attentional-focus instructions (self vs partner focus) and level of partner arousal (high, low and ambiguous) on sexual responding, both objectively and subjectively measured, were examined with sexually-functional (N = 8) and sexually-dysfunctional (N = 8) men. These instructional sets were delivered just before the subjects viewed an erotic film depicting a heterosexual couple in which they identified with the male. When both groups were focusing on themselves rather than their partner, higher tumescence was observed when their partner was displaying low arousal. When the partner's level of arousal was ambiguous, highest tumescence was achieved during partner attentional focus. When the partner was displaying high sexual arousal, functional subjects reached highest levels of tumescence during partner focus, while dysfunctional subjects reached highest levels of tumescence during self focus. In fact, high partner arousal seemed to inhibit dysfunctional subjects' tumescence under partner focus. Examination of self-report of arousal data as measured by a subjective lever revealed interesting group differences. Results are discussed in light of possible maintaining factors in sexual dysfunction and their treatment implications. 相似文献

Cognitive therapy. A 30-year retrospective 总被引:6,自引:0,他引:6

Several lines of investigation have evolved from the initial cognitive model of depression and other disorders. A large number of studies have tested the cognitive model using both clinical and laboratory-based strategies. In general, studies that most closely approximate the clinical conditions from which the theory was derived are supportive of the cognitive model of depression. Studies of anxiety and panic, although fewer, generally support the cognitive model of anxiety and panic. The application to the treatment of clinical problems has been promising and supports the concept of cognitive specificity. The cognitive therapy of depression has led to the utilization of specific cognitive strategies based on the specific conceptualizations of a given disorder to a wide variety of disorders. Study of abnormal reactions has also provided clues to the cognitive structure of normal reactions. 相似文献

Subjects (N = 32) were asked to synchronize a motor response with tones in auditory patterns. These patterns were created from six tones and six intertone intervals of equal duration. The pitch of the first tone differed from the others. It was found that subjects used three types of timing in their motor response: (1) the first intertone interval was prolonged and the second interval was shortened, (2) the second intertone interval was prolonged and the first interval was shortened, and/or (3) the first interval and the second interval were of approximately the same length. The prolongation of the fifth interval was observed during all three types of timing. The results are explained using the concept of suprasegmental control of timing, which explains a prolongation of intervals at critical control point of the patterns. The occurrence of three different strategies of timing is discussed in connection with similar principles in musical performance. 相似文献

Incubated reminiscence effects 总被引:1,自引:0,他引:1
Reminiscence, the recall of material that was not successfully recalled on a previous attempt, was examined in three experiments as a function of the interest (incubation) interval. Incubation intervals inserted between successive recall tests resulted in increased reminiscence, but the effect was seen primarily in the first retested minute. Neither the duration of the initial test (1-4 min), nor the incubation activity (maze problems vs. rest) affected this incubated reminiscence effect. The results support models in which recall tests cause output interference, but incubation intervals reduce it. 相似文献
