If subjects are asked to recollect a former response after having been informed about the correct response, their recollection tends to approach the correct response. This effect has been termedhindsight bias. We studied hindsight bias in an experiment requiring numerical responses to almanac-type questions for physical quantities. We varied (1) the time at which the correct information was provided, (2) the encoding of the original responses by asking/not asking subjects to give a reason for the respective response, and (3) the motivation to recall correctly. We found that hindsight is less biased if reasons are given and if the correct information is provided at an earlier time. Motivation had only interactive effects: (1) With high motivation to recall correctly, the time the correct information was provided had no influence. (2) With reasons given, the variation of motivation showed no effect. These results rule out purely motivational and purely automatic explanations. 相似文献

Fighting pairs of isolated DBA/2 mice showed a significant increase in tail-flick response latencies independent of whether opponents were losing or winning the combat. The effect lasted less than 10 min in both animals. Elevated pain thresholds were also found in isolates that attacked a nonaggressive conspecific, and were prevented by naltrexone (0.2 mg/kg), while a larger dose (1.0 mg/kg) inhibited the attack behavior. A small increase in pain threshold was observed after exposure of isolates to the test box alone, while isolation per se had no effect on baseline tail-flick latencies. The data demonstrate that endogenous pain suppressing systems are activated during attack and suggest that this opioid-mediated antinociception is a correlate of the isolation syndrome, reflecting enhanced arousal of the attacking animal. 相似文献

The potential for contributions by applied social psychology to decision research and theory is explored. Most decisions by groups and individuals are social in origin or impact, suggesting that social psychologists should consider decision making as a relevant topic. Early applied work is considered. Mathematical model approaches are explored. Both are found wanting, especially where we wish to apply our science to complex and multiple uncertain decision problems. Examples of recent relevant research that fit well into an applied social psychological framework are provided, indicating the variety of potential topics for investigations. Finally, the need for encompassing theory is considered. The characteristics of needed theory are discussed. 相似文献

A basic information psychological parameter (BIP) for the reconstruction of concepts of intelligence
Adherents of the Galton paradigm favour the concept that the simple parameter ‘speed of information processing’ has a physiological basis and determines complex achievements assessed in intelligence tests as well as social success. These assumptions are supported by inter-individual correlations. Further supporting evidence comes from total measurement where not only the information content of the stimuli is measured, but also the time to process them. This reveals an individually constant period during which 1 bit of information is processed. It is called the ‘basic period of information processing’ (BIP), which lasts 1/15 s (= 67 ms) in average adults (IQ 100) and is constant over the ranges from which target stimuli can be drawn and over varying modes of the signs (letters, numbers, musical notes, etc.). In representative samples of adults duration of BIP correlates with global IQ (r ? ?0.60): We conclude that the BIP of an adult with an IQ of 122 is 50 ms and with an IQ of 78 twice as long (100 ms). We consider BIP to be a physiological and general determinant of intelligence, being measurable at a ratio or even an absolute scale level. Thus, it appears to be suitable as a building unit for reconstructing the rather fuzzy traditional concept of general intelligence. 相似文献

Research has consistently found that effective leadership is perceived as characterized by traits similar to those associated with masculine gender roles. These perceptions would appear to be at odds with extensive research indicating that effective leadership requires consideration and structuring behaviors—behaviors that seem to represent both masculine and feminine styles. In two separate studies, the correspondence between gender stereotypes and dimensions of effective leadership were assessed. Results indicate that consideration behaviors are perceived to be feminine, while structuring behaviors are perceived to be masculine. Similarly, qualities that characterize the masculine gender role are perceived to be consistent with structuring, while qualities associated with the feminine gender roles are perceived to be consistent with consideration. It is suggested that an increased awareness of the androgynous nature of effective leadership behaviors might weaken the biases in favor of male leaders. 相似文献

The development of a science-wide complexity theory by associates of the Santa Fe Institute provides the opportunity to explore the convergence of behavioral (cognitive/conceptual) complexity theory with science-wide complexity theory. A number of equivalent or similar views of two theories with relevance to human cognition and behavior are discussed. 相似文献

A number of measurement techniques designed to assess cognitive and behavioral complexity are considered. While early measures limit their focus to interpersonal differentiation, later measures consider differentiation, integration, and, in one case, various other aspects of information processing structure. Objective paper-and-pencil measures, subjective response assessment, and simulation technology are briefly described. 相似文献

We report on an observational study on sex differences in serious and playful aggression in early childhood. The sample included 14 girls and 14 boys, aged 2 to 4. The study was carried out in Porto Alegre, Brazil. Half of the subjects attended a nursery school for children from a favela (slum district); the others attended a nursery school that was run by a local university and represented the life conditions of the middle class of the Brazilian society. Each of the children was observed at school for 3 hours (divided into 12–15 minutes episodes) through a focal sampling technique. Significant sex differences are found for the frequency of playful aggression for both the actor's and the victim's part of the aggressive act, but for the actor's role the effect holds only for the middle class setting. There are also tremendous differences between the frequencies of serious aggression in girls and some of the boys, although the effect is not statistically significant. When several types of aggression are compared, it becomes evident that sex differences are restricted to bullying (dominant aggression). The rates of instrumental and reactive aggression are similar in both sexes. Girls and boys from the favela setting do not differ in the relative importance of the different types of serious aggression, but in middle class children the proportion of acts of bullying is much higher in boys than in girls.Revised and elaborated version of the contribution to the Paper Session onFemale Aggression at the90th Annual Meeting of the American Anthropological Association in Chicago, 1991. We thank Claúdio Simon Hutz and Tânia Sperb who helped us to carry out the observations and Simone Schenk and Iris Seltenreich for help in data analysis. We are also grateful to the children and the staff of two nursery schools in Porto Alegre, Brazil, who participated in the study. 相似文献
