Two studies were conducted to demonstrate a bias toward negativity in evaluations of persons or their work in particular social circumstances. In Study 1, subjects evaluated materials written by peers. Those working under conditions that placed them in low status relative to the audience for their evaluations, or conditions that made their intellectual position within a group insecure, showed a clear bias toward negativity in those evaluations. Only individuals who believed their audience to be of relatively low status and at the same time believed their intellectual position to be secure did not show this bias. In Study 2, subjects viewed a videotape of a stimulus person and rated him on several intellectual and social dimensions. Again, subjects believed their audience to be of either relatively high or relatively low status. As a cross dimension, they were given instructions to focus on either the intellectual or the social abilities of the stimulus person while viewing the videotape. A strong main effect of audience status was demonstrated, but only in ratings of intellectual traits; subjects who believed their audience to be of relatively high status rated the stimulus person's intellectual qualities significantly more negatively. Moreover, this effect was independent of the instructional focus subjects had been given. The negativity bias is discussed in the context of previous demonstrations of biases toward weighting negative information more heavily than positive information, as well as previous demonstrations of seemingly pervasive positivity biases in memory and judgment. 相似文献

Eighteen long stay male patients (diagnosis chronic schizophrenia) were involved in a six month token economy prior to random assignment to one of three experimental groups to investigate the importance of social reinforcement and other token-related variables in maintaining improvements brought about by the token system. Assessment included standardised psychiatric rating scales, nurse rating scales, and behavioural measures. Analysis of variance suggests the full token economy system produced significant improvements, but that the social factors involved in token exchanges were not demonstrably important sources of reinforcement. and that none of the variables studies at the experimental phase were critical factors. Once patients returned to a complete token system, results indicate that this may have more value in the promotion of work activities rather than social responding. It is argued that the token system provides a necessary clear structure within which nurses can encourage continuous improvements with long stay patients. 相似文献

To resolve certain empirical and theoretical difficulties concerning, primarily, the significance of phasic heart-rate deceleration prior to reaction signals, 48 children were employed to perform in simple reaction-time tasks while speed, heart rate, head movement, gross movement, and blink activity were recorded. The indeory intervals and level of incentives. Reaction time varied with incentive, with preparatory interval and mode of presentation. Phasic heart-rate deceleration varied with the intervals but not incentive or mode of presentation. There was little relation between deceleration and RT. Heart rate and somatic movement measures (especially of blinking) were roughly concordant at a group level but did not correlate. 相似文献

To learn more about why people falsely confess without external pressure, we examined voluntary blame-taking in three experiments. Drawing from theories of prosocial behavior and social identity, we investigated whether participants' blame-taking is influenced by (a) their relationship with the guilty person (Experiment 1) and (b) the group membership of the person asking to take the blame (Experiments 2a and 2b). In Experiment 1, participants (N = 130) considered whether they would take the blame for a small traffic violation for their best friend and a stranger in a vignette-scenario. As expected, intended blame-taking rates were higher for their best friend (60.8%) than for a stranger (8.5%). Reported reasons for taking the blame included reciprocity and empathy. In Experiments 2a and 2b (Ns = 60; 89), we tested actual blame-taking behavior in two field experiments, using a new experimental paradigm. An experimenter approached participants and asked them to commit insurance fraud for a broken camera. Participants who shared the same group as the person in need were more willing to take the blame (47%-48%) than participants who were from a different group (21%-23%). The most frequently listed reason for taking the blame was empathy. Implications for the occurrence of voluntary blame-taking behavior to protect someone else are discussed. 相似文献

Discounting the value of delayed rewards has primarily been measured in children with the delay of gratification task and in adolescents and adults with the delay discounting task. In the present study, we assessed the suitability of the delay discounting task as a measure of temporal discounting in children. A sample of 7- to 9-year-olds (N = 98) completed a delay discounting task, a delay of gratification task, a sensation seeking measure, and IQ measures. In addition, teacher-based assessments of attention-deficit/hyperactivity disorder traits were measured. The results indicated that the majority of children produced meaningful data on the discounting task and discounted rewards hyperbolically. Children with an elevated risk of attention-deficit/hyperactivity disorder showed a trend towards discounting future rewards on the delay discounting task more steeply than did those at low risk. However, delay discounting was unrelated to either delay of gratification or sensation seeking. We interpret these results as providing some support for the use of delay discounting as a measure of intertemporal choice in children, although the results also suggest that delay discounting and delay of gratification tasks may tap different processes in this population. 相似文献

Untreated rats were observed to either bite or box with Pentobarbital-treated opponents in a shockelicited aggression situation. Specific behaviors such as ataxia movements and submissive postures immediately preceded biting attacks, but rarely boxing whereas behaviors such as moving around the chamber and upright threat postures immediately preceded boxing attacks, but rarely biting. These data suggest that the topography of aggressive behavior of an attacking rat is determined by the behavior of the victim. 相似文献

Two experiments document that conceptual knowledge influences 3-year-olds' extension of novel words. In Experiment 1, when objects were described as having conceptual properties typical of artifacts, children extended novel labels for these objects on the basis of shape alone. When the very same objects were described as having conceptual properties typical of animate kinds, children extended novel labels for these objects on the basis of both shape and texture. Moreover, providing a salient perceptual cue (Experiment 2) did not interfere with children's reliance on conceptual information in extending novel words: when an object with eyes was labeled with a novel word in the context of a story describing the object as an artifact, children extended the label on the basis of shape alone (i.e. as though the object were an artifact). These results, which challenge directly the position that 'dumb attentional mechanisms' can account for word learning, stand as evidence for the central role of conceptual information in mapping words to meaning. 相似文献
