In measurement studies the researcher may wish to test the hypothesis that Cronbach's alpha reliability coefficient is the same for two measurement procedures. A statistical test exists for independent samples of subjects. In this paper three procedures are developed for the situation in which the coefficients are determined from the same sample. All three procedures are computationally simple and give tight control of Type I error when the sample size is 50 or greater.The author is indebted to Jerry S. Gilmer for development of the computer programs used in this study. 相似文献

Previous studies have found that a nonspecific visual event occurring at the fovea 50–150 msec after the onset of a peripheral target delayed the initiation of the saccade to that target. The present studies replicated and extended this finding by studying the effects of both visual and auditory warning signals, by examining the effects of onset and offset warning on manual response latency, and by investigating the effects of presenting the warning events in the periphery of the visual field. The results indicated that the interfering effects occur with visual but not auditory stimuli, with saccades but not motor responses, and when the visual warning event occurs either foveally or in the subject’s periphery. Implications for the processes involved are discussed. 相似文献

The present study examined the role of permissive and nonpermissive cues in mediating the relationship between exposure to erotica and aggression. Male subjects viewed either neutral slides with a silent female or erotic slides with a female who made permissive, nonpermissive, or no comments about the slides. The males rated the slides and subsequently rated the female confederate. Male subjects were then given an opportunity to administer their choice of several intensities of shock to the female in a competitive reaction-time task. Subjects in the permissive cues condition rated the erotic slides as more arousing, saw the female as more reasonable and accepting, and selected more intense shocks for the female than did subjects in the other conditions. One explanation of these results is that permissive cues in the presence of erotica led the male to believe that other normally inappropriate behaviors would be tolerated. 相似文献

The present research was designed to test the hypothesis that perceptions of consensus about the collective experience of psychological problems, as well as the distinctive presence of a community disaster, would affect attributions of externality about such problems. Specifically, it was hypothesized that (1) higher levels of consensus would be associated with greater external attributions of causality, (2) attributions would be more external if the problem began after the disaster (high distinctiveness) than before the disaster, and (3) the occurrence of the disaster would magnify the positive relationship between high consensus and external causality attributions, because of the presence of a distinctive and salient external event. These hypotheses were tested with victims of a flash flood. Results supported the interaction prediction (Hypothesis 3) for the problem of depression, but not for anxiety. In addition, for depression and anxiety, greater consensus was indirectly associated with greater externality, regardless of distinctiveness (Hypothesis 1). However, for somatization, none of the hypotheses were supported. The results are discussed in terms of the applied implications for postdisaster intervention programs to reduce psychopathology. 相似文献

The effect of information integration on the recall of ambiguous prose passages was investigated. In Experiment 1, subjects read ambiguous passages that were difficult to comprehend without titles. In judging the relative positions in the passages of pairs of test sentences, subjects performed better when they read passages headed by a suitable title than when they read untitled passages or received a title at the time of testing. In Experiment 2, subjects provided with a title at encoding also better discriminated complete old sentences from foils composed of fragments of two different old sentences than did subjects provided with no titles or with titles at the time of testing. These two tests index the degree of inter- and intrasentence information integration, respectively. Two findings indicated that integration affected free recall of an ambiguous passage. First, when the degree of integration of the passage's propositions was controlled, free recall of the passage was no different for subjects who did or did not know the passage's title at encoding. Second, inducing subjects to comprehend the passage's sentences individually, without relating them to one another, reduced free recall of the passage. 相似文献

Male and female Canadian undergraduate students identified as extraverts or introverts on the basis of the Eysenck Personality Inventory were administered a questionnaire measuring attitude towards Capital Punishment. Both effects of sex and personality were significant, males and extraverts reporting stronger beliefs in Capital Punishment than females and introverts. These results were interpreted as providing support for Eysenck's proposal that the social attitude dimension of Toughmindedness reflects the personality trait of Extraversion. 相似文献

Two naive human observers were conditioned to report on the slant of a 3.8-cpd sinusoidal grating viewed monocularly with a light-adapted eye and presented at various orientations extending from ?45 to +135 deg. The procedures used yielded a baseline measure of performance and measures obtained during conditioning, extinction, and reconditioning of the tilt-naming response. Both subjects learned rapidly, achieving a level of performance that permits efficient measurement of meridional differences in perceived orientation Ithe oblique effect) at a large number of angles. 相似文献
