In an article in the Journal of Applied Psychology, Vecchio (1990) purported to test cognitive resource theory (Fiedler, 1986; Fiedler & Garcia, 1987). We present evidence that Vecchio's article seriously misrepresented previous work on cognitive resource theory and also contained several flaws in methodology that call into question his conclusions regarding the validity of cognitive resource theory. 相似文献

Several hypotheses derived from P. Brown and Levinson's (1987) politeness theory were tested with Ss from the United States and Korea. Ss imagined themselves in situations in which they were to make a request. They then indicated exactly what they would say in each situation and what their perceptions of the request size, the hearer's power, and the closeness of their relationship with the hearer were. Consistent with P. Brown and Levinson's theory, power, distance, and size contributed significantly to politeness. Significant predictor variable interactions suggested that an additive model is not appropriate. Finally, there was evidence of cultural and gender differences in the weighting of these predictor variables. These differences can partially account for cultural and gender differences in language use. 相似文献

A brief, simple measure of different types of attributions for partner behavior was examined in 3 studies of married couples. Reliability was established by high internal consistency and test-retest correlations. Causal and responsibility attribution scores correlated with marital satisfaction, attributions for marital difficulties, and attributions for actual partner behaviors generated by spouses. Responsibility attributions were related to (a) reported anger in response to stimulus behaviors used in the measure and (b) the amount of anger displayed by wives during a problem-solving interaction with their partner. The extent to which husbands and wives whined during their discussion also correlated with their responsibility attributions. The results address several problems with existing assessments, and their implications for the measurement of attributions in marriage are discussed. 相似文献

Humans and monkeys show intermittent arm movements while tracking moving targets. This intermittency has been explained by postulating either a psychological refractory period after each movement and/or an error deadzone, an area surrounding the target within which movements are not initiated. We present a technique to detect and quantify the size of this deadzone, using a compensatory tracking paradigm that distinguishes it from a psychological refractory period. An artificial deadzone of variable size was added around a visual target displayed on a computer screen. While the subject was within this area, he received visual feedback that showed him to be directly on target. The presence of this artificial deadzone could affect tracking performance only if it exceeded the size of his intrinsic deadzone. Therefore, the size of artificial deadzone at which performance began to be affected revealed the size of the intrinsic deadzone. Measured at the subjects' eye, the deadzone was found to vary between 0.06 and 0.38 degrees, depending on the tracking task and viewing conditions; on the screen, this range was 1.3 mm to 3.3 mm. It increased with increasing speed of the target, with increasing viewing distance, and when the amplitude of the movement required was reduced. However, the deadzone size was not significantly correlated with the subjects' level of performance. We conclude that an intrinsic deadzone exists during compensatory tracking, and we suggest that its size is set by a cognitive process not simply related to the difficulty of the tracking task. 相似文献

Stimulus recognition and the mere exposure effect. 总被引:5,自引:0,他引:5
A meta-analysis of research on Zajonc's (1968) mere exposure effect indicated that stimuli perceived without awareness produce substantially larger exposure effects than do stimuli that are consciously perceived (Bornstein, 1989a). However, this finding has not been tested directly in the laboratory. Two experiments were conducted comparing the magnitude of the exposure effect produced by 5-ms (i.e., subliminal) stimuli and stimuli presented for longer durations (i.e., 500 ms). In both experiments, 5-ms stimuli produced significantly larger mere exposure effects than did 500-ms stimuli. These results were obtained for polygon (Experiment 1), Welsh figure (Experiment 2), and photograph stimuli (Experiments 1 and 2). Implications of these findings for theoretical models of the mere exposure effect are discussed. 相似文献

Why do people need self-esteem? Converging evidence that self-esteem serves an anxiety-buffering function. 总被引:5,自引:0,他引:5

Three studies were conducted to assess the proposition that self-esteem serves an anxiety-buffering function. In Study 1, it was hypothesized that raising self-esteem would reduce anxiety in response to vivid images of death. In support of this hypothesis, Ss who received positive personality feedback reported less anxiety in response to a video about death than did neutral feedback Ss. In Studies 2 and 3, it was hypothesized that increasing self-esteem would reduce anxiety among individuals anticipating painful shock. Consistent with this hypothesis, both success and positive personality feedback reduced Ss' physiological arousal in response to subsequent threat of shock. Thus, converging evidence of an anxiety-buffering function of self-esteem was obtained. 相似文献
