This quantitative review of 130 comparisons of interindividual and intergroup interactions in the context of mixed-motive situations reveals that intergroup interactions are generally more competitive than interindividual interactions. The authors identify 4 moderators of this interindividual-intergroup discontinuity effect, each based on the theoretical perspective that the discontinuity effect flows from greater fear and greed in intergroup relative to interindividual interactions. Results reveal that each moderator shares a unique association with the magnitude of the discontinuity effect. The discontinuity effect is larger when (a) participants interact with an opponent whose behavior is unconstrained by the experimenter or constrained by the experimenter to be cooperative rather than constrained by the experimenter to be reciprocal, (b) group members make a group decision rather than individual decisions, (c) unconstrained communication between participants is present rather than absent, and (d) conflict of interest is severe rather than mild. 相似文献

Electromyographic (EMG) and temporal artery vasomotor activity was evaluated in three groups of headache patients (tension, migraine and combined) and nonheadache control subjects while in reclining, sitting and standing positions. Analysis of the EMG data revealed that at all measurement sites (bilateral frontalis, bilateral trapezius) the three headache groups demonstrated significantly higher levels than the nonheadache group but did not differ from each other. A secondary analysis of the trapezius EMG data revealed that a large percentage of headache patients had “normal” EMG levels in the reclining position but showed abnormalities in the sitting and standing positions. Analysis of the left temporal artery vasomotor activity revealed that all three headache groups vasoconstricted to a significantly greater extent than the nonheadache group in the sitting and standing positions. However, a diagnosis by position interaction was found for the right temporal artery with the migraine group demonstrating a unique pattern of activity. 相似文献

The domains-interaction approach, originally developed in metaphor research, was used to model humor processing. Using jokes of the structure A is the B of A's domain (e.g., John Candy is the hamburger of actors), this approach allows for precise operationalizations of incongruity and resolution in terms of between-domain and within-domain semantic distance, respectively. Distances between 26 terms used in 250 of these simple jokes were derived from semantic differential ratings. As predicted, humor ratings of the jokes were positively correlated with incongruity (between-domain distance) but not with resolution (within-domain distance). Also as predicted, a significant interaction revealed that jokes with both incongruity and resolution were rated as most humorous. These findings were replicated in a second study. A third study indicated that humor perception differs from metaphor appreciation, showing main effects for both types of semantic distance, but no interaction, when the sentences were presented as metaphors instead of jokes and rated for aptness.The authors wish to thank Richard Harshman and Albert Katz for their helpful suggestions in conducting this research. 相似文献

Research and theory on employee job satisfaction and well-being has increasingly concentrated on both intrinsic and extrinsic motivational factors. According to self-determination theory (Deci & Ryan, 1985). autonomy, relatedness, and competence are three intrinsic psychological needs that, if fulfilled in the workplace, will lead to greater satisfaction, performance, and general well-being. This study examines employee and supervisor perceptions of the employee's autonomy, competence, and relatedness in the workplace, as well as the degree and direction of discrepancies between employee and supervisor reports. Both employee and supervisor ratings of intrinsic motivational factors were significantly related to work satisfaction, psychological health, and self-esteem, after controlling for the extrinsic factors of pay and job status. Results of discrepancy analyses were somewhat supportive of overrating being associated with greater well-being and job satisfaction. Discussion of the results ties this study to relevant research from a self-determination perspective and to the growing literature on discrepancies and self-perception. 相似文献

Transitions between the coordinative patterns of rhythmically moving human arms and legs were studied to test the predictions of a four-component model (Schöner, Jiang and Kelso, 1990). Based upon results from previous two-component experiments (Kelso and Jeka, 1992), three assumptions were made about the four-limb system: (1) all limb pairs produce stable in-phase and anti-phase patterns; (2) the coupling between homologous limbs (i.e., right and left arms or right and left legs) is appreciably stronger than the coupling between nonhomologous limbs (i.e., arm and leg); and (3) right-left symmetry. An analysis of a four-component model (Jeka, Kelso and Kiemel, 1993) led to the prediction of four attracting invariant circles, each with two stable patterns in the state space of four-limb dynamics. In an experiment to test this prediction, subjects were required to cycle all four limbs in one of the eight patterns to the beat of an auditory metronome whose frequency was systematically increased. All subjects demonstrated spontaneous transitions corresponding to pathways along the invariant circles. Pre-transition relative phase variability increased with required frequency up to the transition, suggesting that loss of pattern stability induced the observed transitions. Thus, despite a large number of potential transitions, differential coupling between limb pairs and symmetry of the pattern dynamics restricts the behavior of the human four-limb system to a limited area of its state space. 相似文献

This investigation assessed the effects of presenting non-target stimuli in the antecedent and consequent events on the future learning of responses to those stimuli. A 4-s constant time delay procedure was implemented to teach students with mild to moderate disabilities to read sight words. Future target stimuli (i.e., stimuli that were presented during instructional sessions of initial target stimuli, but were not directly instructed or targeted) were presented in one of two conditions; (a) in the antecedent event, or (b) in the consequent event portion of each instructional trial. Future target stimuli consisted of sight words that were unrelated to the target stimuli. An adapted alternating treatments design was used to assess and compare the two instructional conditions. Also, after students achieved criterion for reading target sight words, constant time delay was implemented to teach the future target stimuli. The number of sessions and the number and percentage of errors through criterion for teaching target and future target stimuli were assessed to measure the efficiency of the two conditions. All students reached criterion on the target stimuli and then acquired the future target stimuli when taught. Students required fewer sessions to achieve criterion on future target stimuli compared to initial target stimuli. There were minimal differences between the two conditions (i.e., antecedent versus consequent). 相似文献

Williams syndrome (WS) is a rare genetic disorder that results in severe visual-spatial cognitive deficits coupled with relative sparing in language, face recognition, and certain aspects of motion processing. Here, we look for evidence for sparing or impairment in another cognitive system-object recognition. Children with WS, normal mental-age (MA) and chronological age-matched (CA) children, and normal adults viewed pictures of a large range of objects briefly presented under various conditions of degradation, including canonical and unusual orientations, and clear or blurred contours. Objects were shown as either full-color views (Experiment 1) or line drawings (Experiment 2). Across both experiments, WS and MA children performed similarly in all conditions while CA children performed better than both WS group and MA groups with unusual views. This advantage, however, was eliminated when images were also blurred. The error types and relative difficulty of different objects were similar across all participant groups. The results indicate selective sparing of basic mechanisms of object recognition in WS, together with developmental delay or arrest in recognition of objects from unusual viewpoints. These findings are consistent with the growing literature on brain abnormalities in WS which points to selective impairment in the parietal areas of the brain. As a whole, the results lend further support to the growing literature on the functional separability of object recognition mechanisms from other spatial functions, and raise intriguing questions about the link between genetic deficits and cognition. 相似文献
