This study assessed the role of adaptive versus maladaptive coping behaviors and personal characteristics in influencing the affective reactions of managers to four role stressors. Maladaptive coping was found to moderate the relationships of several role stressors with felt stress and job satisfaction. Maladaptive coping and trait anxiety also demonstrated independent additive effects on felt stress and job satisfaction over and above that of all four stressors. 相似文献

Two studies tested the effects of TV ads with celebrity endorsement on the product preference and understanding of 8- to 14-year-old boys. Study 1 compared two ads for a model racer. One had celebrity endorsement (by a famous race driver) and footage of real automobile racing featuring the celebrity (live action); the second had neither feature. Study 2 employed one ad for a different brand of model racer edited to generate a 2 (endorser presence) by 2 (inclusion of live racetrack action) factorial design. A total of 415 boys were exposed to one of the experimental ads or a control ad, embedded in a new animated children's adventure program. Preference for the advertised brand of model racer (pre- and postviewing) and a number of cognitive variables were assessed. Exposure to endorsement led to increased preference for the toy and belief that the celebrity was expert about the toy. Live action led to exaggerated estimates of the physical properties of the toy and the belief that the ad was not staged. The 8- to 10-year-olds associated the glamour of the endorser with the toy and were more reliant on his advice than were 11- to 14-year-olds. However, the two age groups were not differentially affected by the ads. Contrary to the speculation of many researchers, understanding about advertising intent and techniques and cynicism about ads had almost no influence on product preference after viewing. 相似文献

Research is reviewed which suggests that hyperventilation syndrome is an underdiagnosed disorder for the presentation of many patients experiencing apparent anxiety states. In a test of this hypothesis, 21 normal individuals (9 female) underwent a 2 min period of intentional hyperventilation following a 10 min baseline phase. Hyperventilation was accompanied by increased subjective anxiety and tachycardia, and indications of peripheral vasoconstriction. Following hyperventilation, Ss experienced increased levels of state anxiety and perceived autonomic arousal, as indexed by self-report instruments. These results support the hypothesis that undiagnosed hyperventilatory phenomena may be etiologically implicated in states of pathologic anxiety. 相似文献

New theological understanding can emerge with the advancement of scientific knowledge and the use of new concepts, or older concepts in new ways. Here, the authors present a proposal to extend the concept of “rescue and recovery” found in the United Nations Law of the High Seas, off-world and within a broader purview of other intelligent and self-aware species that humans may someday encounter. The notion of a morality that extends to off-world species is not new, but in this analysis, rescue and recovery become an imperative when any intelligent and self-aware species is in harm's way. Rescue and recovery encompass a necessary action component except perhaps in those cases where rescuers are in danger. The authors explore three biblical examples of rescue and recovery to derive a fundamental meaning of the concept. 相似文献

von W right J. M. Free recall of repeated words as a function of intralist variability. Scand. J. Psychol ., 1972, 13 , 39–42.—Five "critical" words were repeated 4 times each in constant positions within lists of 80 items. The number of different filler words, and the order of the repeated filler words, was varied between lists. In free recall tests total recall was approximately constant, but the recall of the critical words was significantly better the greater the variation in the intralist context of these words, especially the greater the number of different filler words. The results are interpreted in terms of the encoding variability hypothesis. 相似文献

Three Ss made judgments of the presence or absence of a burst of 60-cps vibration onthe index fingertip.The probability of S’s reporting the presence of a signal was found to be influenced by signal probability and signal intensity. Mean reaction time for reporting the presence of a signal decreased as a function of signal intensity and signal probability whereas mean reaction time for reporting the absence of a signal increased as a function of signal intensity and signal probability. On trials where no signal was presented mean R T for reporting a signal decreased with increases in the signal probability whereas mean RT for reporting the absence of a signal increased with increases in signal probability. The results were interpreted as support for the hypothesis that S’s decision time was longer the closer on the sensory continuum a particular observation was to his criterion. 相似文献

Following monocular fixation of a red stimulus figure on a grey background, a projection field having the same colour as the stimulus figure was viewed either with ( a ) the stimulated eye, or ( b ) the non-stimulated eye. In case ( a ) the after-image appeared grey on a red background, but in case ( b ) green or blue, on a red background. In the latter case the brightness and to some extent the hue of the after-image varied when the amount of light coming to the originally stimulated eye varied. The data are in agreement with the assumption that after-images are primarily retinal. 相似文献

Changes in the dimensionality of the moral criteria, i.e. of those aspects of an action-sequence to which a person pays attention when judging how good/bad (nice/naughty) the agent is, were studied with 7-, 10-, and 13-year-old girls and adult subjects. Action sequences varying in respect to potential moral criteria were presented as cartoons. A proximity setting technique and Kruskal's (1964) method of analysis were used. In the younger age groups a remorse-spite-dimension was obtained, the motive criterion becoming more dominant and differentiated with age. Methodological problems are discussed. 相似文献
