The purpose of this study was to ascertain whether there is a differential relationship in the socialization of children with respect to gender identification when responses of children were examined with respect to race and sex (N = 596 fifth and sixth grade boys and girls). Strong father preference was found to have no effect on the choice a boy will make when choosing between male and female peers, during preadolescence, while a strong mother preference by a girl is related to the sex of the peers she chooses. Preadolescent girls who identify with their mothers chose girls with whom to interact in a variety of activities more frequently than they chose boys. A greater proportion of girls preferred to engage in activities with their mothers than boys preferred to engage in activities with their fathers. No differences were observed between racial groups in terms of girls' choices involving peers. Black boys, however, preferred to engage in activities with opposite-sex rather than same-sex peers to a greater extent than white boys. 相似文献

ABSTRACT Ecological dynamics characterizes adaptive behavior as an emergent, self-organizing property of interpersonal interactions in complex social systems. The authors conceptualize and investigate constraints on dynamics of decisions and actions in the multiagent system of team sports. They studied coadaptive interpersonal dynamics in rugby union to model potential control parameter and collective variable relations in attacker–defender dyads. A videogrammetry analysis revealed how some agents generated fluctuations by adapting displacement velocity to create phase transitions and destabilize dyadic subsystems near the try line. Agent interpersonal dynamics exhibited characteristics of chaotic attractors and informational constraints of rugby union boxed dyadic systems into a low dimensional attractor. Data suggests that decisions and actions of agents in sports teams may be characterized as emergent, self-organizing properties, governed by laws of dynamical systems at the ecological scale. Further research needs to generalize this conceptual model of adaptive behavior in performance to other multiagent populations. 相似文献

ABSTRACT. Predicting behavior has been a main challenge in human movement science. An important step within the theory of coordination dynamics is to find out the rules that govern human behavior by defining order parameters and control parameters that support mathematical models to predict the behavior of a system. Models to describe human coordination have been focused on interlimb coordination and on interpersonal coordination in affiliative tasks but not on competitive tasks. This article aims to present a formal model with two attractors to describe the interactive behavior on a 2v1 system in rugby union. Interpersonal distance and relative velocity critical values were empirically identified and were included as task constraints that define the attractor landscape. It is shown that using relative velocity as a control parameter the model offers reasonable prediction concerning the decision-making process. The model has the plasticity to adapt to other settings where interpersonal distances and relative velocities amongst system components act as significant task constraints. 相似文献

In this article, the focus is on a comparison of suicide attempts and substance abuse in the United States. It is argued that suicide attempts and substance abuse may function as psychologically equivalent but gender-specialized forms of self-injurious behaviors. Possible explanations for the gender segregation of suicide attempts and substance abuse are reviewed, and the benefits of crossover theories and treatments are presented. 相似文献

This research is an investigation of the hedonic intensities of elation and disappointment following the outcomes of risky gambles using two principles: disappointment aversion and the principle of limited emotion processing. Disappointment aversion implies a stronger impact of disappointment compared with elation; the principle of limited emotion processing predicts a smaller impact of elation if it occurs with a real gain, and a smaller impact of disappointment if it occurs with a real loss. Both principles support each other in the gain domain but operate against each other in the loss domain. It was predicted that disappointment would outweigh elation in the gain domain. For the loss domain, this question was left open to empirical scrutiny. Participants were provided with hypothetical gambles and were required to imagine having won, not won, lost, or not lost, money. Results supported the prediction for the gain domain; mixed results emerged for the loss domain. The model adds to the understanding of the cognitive and emotional processes following the outcomes of risky events. 相似文献

This article examines trends that are impacting democratic rationality. It is found that the trends are almost uniformly negative. Viewed from within the legislative branch, trends are negatively impacting legislators’ time, complexifying problems, constraining options, and limiting the evaluation of options. Trends external to the legislative branch are reducing citizen participation and knowledge about public affairs, skewing the balance of power among the branches and states, and decreasing accountability of public officials. In combination, democratic rationality, the process of making good, efficient, and timely decisions to promote higher quality of life and the public good, is seriously threatened. Recommendations include public financing of campaigns, more structured legislative decision-making processes, simplification tests for all new legislation and regulations, and a major new initiative to foster public involvement in public decision making. 相似文献

Groups often struggle to distinguish expert members from others who stand out for various reasons but may not be particularly knowledgeable (Littlepage & Mueller, 1997). We examined an intervention designed to improve group decision making and performance through instructing group members to search for information they already possessed that was relevant to a problem. Participants estimated values and expressed their confidence in their estimates individually and then a second time either individually or in a group. This was done with or without the intervention. Results indicated that: (1) groups were more confident than, and out-performed, individuals, (2) group decision making was best captured by models predicting more influence for more accurate members when the intervention was used and more influence for more confident members in its absence, and (3) groups that received the intervention out-performed groups that did not. 相似文献

We examined the consequences of personal savings estimate inflation that occurs when decision makers provide savings estimates for specific future months when compared with the next month or the next year time frames, along with a method to attenuate this bias. The results of three experiments showed that the savings estimate inflation leads to significantly larger estimates of desired nest egg size (Experiment 1) and preference for riskier choices in other financial domains such as investment and employment decisions (Experiment 2). An attempt to attenuate this bias revealed that it is corrected when individuals provide a budgeting estimate prior to giving a savings estimate (Experiment 3). The theoretical and practical implications of the findings are discussed. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The decision strategy used to select a choice set from an array of alternative options is known to affect the composition of the final choice set. Specifically, individuals incorporate more answers into their choice set when it is created by eliminating implausible items than when the set is created through the inclusion of plausible options. This difference is accounted for in a decision framework that posits a general reluctance to change the status quo (i.e., actively include or exclude an item). We extended this work to investigate, not only the decisions themselves, but also metacognitive judgments (i.e., confidence in the accuracy of the choice set). In two face recognition experiments, we tested the impact of decision strategy (Experiment 1) and confidence judgment strategy (Experiment 2) on the confidence–accuracy relationship. In Experiment 1, participants completed two blocks of recognition trials, one under inclusion (marking previously seen faces) and one under elimination (marking previously unseen faces) instructions. We observed superior resolution (i.e., discrimination between correct and incorrect) for inclusion trials, but only when they were completed prior to use of the elimination strategy. In Experiment 2, all participants completed face recognition trials under inclusion instructions, but we manipulated the strategy used to assess confidence. Again, we observed a significant impact of strategy on confidence–accuracy resolution. Thus, we observed that both the strategy employed to reach a decision and that employed to assess confidence affected the confidence–accuracy relationship. We discuss theoretical and applied (particularly for eyewitness identification and multiple‐choice testing) implications. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Decision reversals often imply improved decisions. Yet, people show a strong resistance against changing their minds. These are well‐established findings, which suggest that changed decisions carry a subjective cost, perhaps by being more strongly regretted. Three studies were conducted to explore participants' regret when making reversible decisions and to test the hypothesis that changing one's mind will increase post‐outcome regret. The first two studies employed the Ultimatum game and the Trust game. The third study used a variant of the Monty Hall problem. All games were conducted by individual participants playing interactively against a computer. The outcomes were designed to capture a common characteristic of real‐life decisions: they varied from rather negative to fairly positive, and for every outcome, it was possible to imagine both more and less profitable outcomes. In all experiments, those who changed their minds reported much stronger post‐outcome regret than those who did not change, even if the final outcomes were equally good (Experiments 2 and 3) or better (Experiment 1).This finding was not because of individual differences with respect to gender, tendency to regret, or tendency to maximize. Previous studies have found that those who change from a correct to wrong option regret more than those who select a wrong option directly. This study indicates that this finding is a special case of a more general phenomenon: changing one's mind seems to come with a cost, even when one ends up with favorable outcomes.
