This study investigated the effects of video game play on aggression. Using the General Aggression Model, as applied to video games by Anderson and Bushman, [2002] this study measured physiological arousal, state hostility, and how aggressively participants would respond to three hypothetical scenarios. In addition, this study measured each of these variables multiple times to gauge how aggression would change with increased video game play. Results showed a significant increase from baseline in hostility and aggression (based on two of the three story stems), which is consistent with the General Aggression Model. This study adds to the existing literature on video games and aggression by showing that increased play of a violent first person shooter video game can significantly increase aggression from baseline. 相似文献

The term conceptual simulation refers to a type of everyday reasoning strategy commonly called \"what if\" reasoning. It has been suggested in a number of contexts that this type of reasoning plays an important role in scientific discovery; however, little direct evidence exists to support this claim. This article proposes that conceptual simulation is likely to be used in situations of informational uncertainty, and may be used to help scientists resolve that uncertainty. We conducted two studies to investigate the relationship between conceptual simulation and informational uncertainty. Study 1 was an in vivo study of expert scientists; the results suggest that scientists do use conceptual simulation in situations of informational uncertainty, and that they use conceptual simulation to make inferences from their data using the analogical reasoning process of alignment by similarity detection. Study 2 experimentally manipulated experts' level of uncertainty and provides further support for the hypothesis that conceptual simulation is more likely to be used in situations of informational uncertainty. Finally, we discuss the relationship between conceptual simulation and other types of reasoning using qualitative mental models. 相似文献

We study a class of sequential selection and assignment problems in which a decision maker (DM) must sequentially assign applicants to positions with the objective of minimizing expected cost. In modeling this class of problems, we assume that on each period the DM is only informed of the rank of the present applicant relative to the applicants that she previously observed and assigned. We first present the optimal decision policy that we subsequently use as a normative benchmark, and then report results from three experiments designed to study sequential assignment behavior. In comparing the aggregate results from all three experiments to the optimal decision policy, we identify a systematic bias, called the middleness bias, to over‐assign applicants to intermediate positions. The results also reveal a strong bias for early applicants to be over‐assigned to important positions. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

An overview of the field of evolutionary consumption is provided. Brief summaries of disciplines within the evolutionary behavioral sciences that preceded evolutionary psychology (EP) are first offered. This is followed by a discussion of important EP principles including the domain-specificity of the human mind, and the difference between ultimate and proximate scientific explanations. The evolutionary bases of memory, attitude formation/change, emotions, perception (our five senses), personality, and decision making are addressed next, along with specific links to consumer research. Next, I demonstrate how numerous consumer acts could be classified into one of four basal Darwinian modules: survival, reproduction (mating), kin selection, and reciprocal altruism. The paper continues with an exploration of the evolutionary roots of cultural products (e.g., song lyrics) and Darwinian happiness (along with the evolutionary etiology of maladaptive phenomena such as pathological gambling and compulsive buying). I conclude with a discussion of key epistemological benefits of Darwinizing consumer research including greater consilience, increased interdisciplinarity, and an ethos of methodological pluralism. 相似文献

This study examines the relationships between intrinsic/extrinsic aspirations and subjective well‐being (SWB; positive affect, negative affect, satisfaction with life) in a sample of 583 Spanish adults. Firstly, the results showed that high scores for SWB are related to high scores for intrinsic aspirations and, to a lesser extent, to low scores for extrinsic aspirations; it was also found that intrinsic aspirations are mainly related to positive indicators of well‐being, whereas extrinsic aspirations are mainly associated with negative indicators. Secondly, the study also enabled exploration of the links between the domains of the Five‐Factor Model and aspirations; thirdly, the results showed that intrinsic/extrinsic aspirations predict SWB beyond the Five Factors. The results demonstrate the importance of studying the content of human aspirations for understanding psychological health. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Five individuals with autism or other developmental disabilities participated in paired-stimulus preference assessments during repeated baseline probes. All subjects initially showed a pronounced bias by typically selecting the stimulus placed in either the left or right position. Biased responding for 3 subjects was eliminated when training trials were conducted in which a stimulus of known lesser quality was presented as one of the choices. Reinforcer-quality training was unsuccessful for 2 subjects, as was a condition in which reinforcer magnitude was modified to favor unbiased responding. These subjects' biased responding was eliminated only when a correction procedure (repetition of error trials) was implemented. 相似文献

ABSTRACTThis article proposed that after social exclusion, individuals may react in a hostile or amiable manner, which depends on the type of categorical similarity cues that new groups possess. For excluded individuals, groups that resemble their excluder would provoke a defensive attitude. They also exhibit hospitality to groups that resemble themselves to gain inclusion. In Experiment 1, social exclusion was manipulated by providing a scenario story regarding an individual who was excluded and subsequently wanted to join in new groups. The results indicated that participants in the social exclusion condition avoided groups that resembled the previous excluder, whereas groups that fit their characteristics were preferred. In experiment 2, the cognitive load was manipulated. Heavy cognitive load made participants in the social exclusion condition only avoid groups that resembled the excluder; in contrast, they exhibited no preference for groups that may be suitable for them. 相似文献

This review focuses on parallels between the selectionist sciences of evolutionary biology and behavior analysis. In selectionism, complex phenomena are interpreted as the cumulative products of relatively simple processes acting over time—natural selection in evolutionary biology and reinforcement in behavior analysis. Because evolutionary biology is the more mature science, an examination of the factors that led to the triumph of natural selection provides clues whereby reinforcement may achieve a similar fate in the science of behavior. 相似文献
