An anxiety-related bias in semantic activation when processing threat/neutral homographs 总被引:3,自引:0,他引:3
Anne Richards Christopher C. French 《The Quarterly Journal of Experimental Psychology Section A: Human Experimental Psychology》1992,45(3):503-525
Three experiments are reported comparing high and low-trait anxious subjects in terms of their patterns of semantic activation in response to ambiguous primes, with one threat-related and one neutral meaning. Such primes were followed by targets related to either their threat or neutral meaning, or by unrelated targets, in a lexical decision task. Experiments 1 to 3 employed stimulus onset asynchronies (SOAs) of 750 msec, 500 msec, and 1250 msec, respectively. At 500-msec SOA all subjects showed facilitation for both meanings. At 750-msec SOA the only significant priming effect was that for the threat-related meaning in the high-anxiety group, and a similar trend was found at 1250-msec SOA. Consideration of the patterns of priming for targets following ambiguous threat/neutral primes suggest that at the longer SOAs, high-anxiety subjects consciously “lock on” to a threatening interpretation if one has been made available by earlier automatic spreading activation. 相似文献

Depression is a common problem among college women, and many of them cope with it on their own (without professional help). Since these naturally occurring episodes of self-controlled behavior are frequent—and sometimes dramatically successful—they were investigated in this study. College women who had coped successfully and unsuccessfully with clinically-significant levels of depression were interviewed about their coping efforts. In contrast to previous research of this type, the present investigation did not identify any clear coping differences between successful and unsuccessful copers. Follow-up interviews indicated that many initially unsuccessful subjects eventually became much less depressed. The implications of these results are discussed, with suggestions for future research. 相似文献

A concurrent-chain schedule was employed to examine pigeons' preferences for signaled versus unsignaled delay of reinforcement in which the delay durations ranged from zero to ten seconds. In general, pigeons preferred signaled delay over unsignaled delay especially when a variable-interval 30-second schedule operated in each initial link; when a variable-interval 90-second schedule operated in each initial link, these preferences tended toward indifference or were attenuated. In addition, prior training seemed to exert partial control over behavior. Responding in the terminal link was higher under signaled delay than unsignaled delay in a majority of the cases. Moreover, response rates under signaled delay remained fairly constant whereas responding under unsignaled delay was initially high, but decreased systematically with delay durations as short as 2.5 seconds. These results are consistent with a number of other studies demonstrating the significant role of a signal for impending positive stimuli. 相似文献

Some researchers have suggested that a precondition of affective submissiveness may increase the likelihood of female victimization in sexual assault, whereas others have suggested that criminal offenders use perceptions of vulnerability when selecting a victim. In this study, based on American college students, men (decoders) rated videotaped women (encoders) dominant versus submissive using a semantic differential instrument. Cue evaluators analyzed the body language and appearance of the videotaped women using a Likert instrument. The results suggest that (a) men form differentiated perceptions of dominant versus submissive women, (b) such perceptions substantially rely on nonverbal cues, (c) dominant and submissive women display visually different behaviors and appearances, and (d) men tend to select submissive females for exploitation. 相似文献

Time reproductions by H.M 总被引:2,自引:0,他引:2

Time reproductions by a subject with a severe memory loss were normal only for intervals less than 20 sec. For longer intervals, the reproduced intervals were roughly proportional to the square root of the standard intervals, plus 20 sec. 相似文献

Ss provided judgments of pairwise stimulus similarities for 21 12-turn random forms in two experimental tasks: a scaling task, involving a variant of the method of graded dichotomies, and a sorting task, which simply required Ss to categorize the forms. The grouped data from both tasks, when analyzed using nonmetric multidimensional scaling techniques, yielded five-dimensional configurations with euclidean distances. The correspondence of these two spaces, assessed using canonical correlations, was extremely good. The psychological dimensions derived from both tasks were related to two sets of physical measures on the forms: the factor space suggested by Brown and Owen and a set of more basic physical measures. Physical cues of greatest importance involved size, dispersion, angularity, and rotation measures. The value of the tasks and the utility of the Brown and Owen measures were discussed. 相似文献
