Wearing costumes is a common experience during early childhood and is often important to sociodramatic play. Costumes tend to be highly gendered for both girls and boys (such as princess and superhero costumes). However, there is very little research on the impact that wearing costumes has on gender-differentiated behavior, such as toy preference, prosocial behavior, or perseverance during early childhood. The current study included 223 U.S. children, aged between 3 and 5 years-old. Children were assigned to wear either a gendered, counter-gendered, or gender-neutral costume, and they then took part in three gender-related tasks. There was no impact of wearing costumes on any task for girls. However, boys preferred feminine toys significantly more when wearing a neutral costume when compared to a masculine-typed one. Additionally, boys were significantly less likely to help when wearing a masculine-typed costume compared to a feminine-typed costume. There are several implications of these findings that are discussed in the paper. Parents may wish to purchase a wide range of costumes for their child for sociodramatic play, particularly for boys. Therapists could also potentially use costumes during play therapy to discuss gender issues. Additionally, costume producers could consider marketing a wide range of costumes for children as opposed to largely focusing on gendered ones.

The authors examine how political ideology impacts consumer preferences for hedonic and utilitarian choices and the underlying reasons for these differences. Five studies indicate that conservatives are less tolerant of ambiguity than liberals, leading to a preference for utilitarian options, whereas liberals are more tolerant of ambiguity leading to a preference for hedonic options. However, these preferences were reversed when utilitarian options were framed as ambiguous and hedonic options were framed as explicit and clear.  相似文献

This article traces the origins of language about ‘theories’ of the atonement in Friedrich Schleiermacher and F.C. Baur’s historicization of Protestant theology in Germany. It follows the growth and promulgation of this conceptualization as it spread to America and Great Britain in the later nineteenth century. This approach contributed to the growth and development of the doctrine and its history, while severely limiting it in important ways. I note four dangers implicit within uncritical use of ‘theory’ language in studies of the history of the doctrine of the atonement, and conclude by arguing that a more fitting approach lies in the ancient and medieval concept of theoria, or contemplation, which serves as the broader telos for appreciating the riches we have in the work of Christ, within which modest contemporary notions of theory can and should play a role.  相似文献

Differential reinforcement is a common treatment for escape-maintained problem behavior in which compliance is reinforced on a fixed-ratio (FR) 1 schedule with brief access to positive and/or negative reinforcement. Recent research suggests some individuals prefer to complete longer work requirements culminating in prolonged (i.e. accumulated) reinforcement periods relative to brief (i.e. distributed) periods, but prolonged work exposure may evoke problem behavior and prevent compliance from contacting reinforcement when treating escape-maintained problem behavior. We exposed 3 children with escape-maintained problem behavior to both distributed (FR 1 resulting in 30 s of reinforcement) and accumulated (FR 15 resulting in 7.5 min of reinforcement) arrangements to compare their efficacy in maintaining low levels of problem behavior. We then assessed participants' preferences for these conditions in a concurrent-chains arrangement. Accumulated-reinforcement arrangements did not occasion additional problem behavior, but rather resulted in consistently lower levels of problem behavior for 2 of 3 participants. Participants demonstrated idiosyncratic preferences.  相似文献

Functional Communication Training (FCT) involves arranging extinction for problem behavior and reinforcement for a more desirable, functionally equivalent, communicative response (FCR). Although effective under ideal arrangements, the introduction of delays to reinforcement following the FCR can result in increased problem behavior. Austin and Tiger (2015) showed that for individuals whose problem behavior was sensitive to multiple sources of reinforcement, providing access to alternative, functional reinforcers during delays mitigated this increase in problem behavior during delay fading. The current study replicated the procedures of Austin and Tiger with 2 individuals displaying multiply controlled problem behavior. Providing alternative functional reinforcers reduced problem behavior during 10-min delays for both participants without requiring delay fading.  相似文献

Murray Sidman's contributions to the science of behavior span many areas including avoidance behavior, coercion and its effects, stimulus control, errorless learning, programmed learning, stimulus equivalence, and single-subject methodology. He was also a great mentor to many and helped shape the discipline we now call behavior analysis. In this memoriam, we briefly highlight his scholarly legacy and share some personal anecdotes.  相似文献

Scholars are paying increasing attention to the “dark side” of citizenship behavior. One aspect of this dark side that has received relatively scant attention is “helping pressure”—an employee's perception that s/he is being encouraged to, or otherwise feels that s/he should, enact helping behavior at work. Drawing from theory associated with work stress, we examine affective and cognitive mechanisms that potentially explain why helping pressure, counterintuitively, may lead employees to engage in deviant behavior instead. Beyond examining these possible mechanisms, we also answer calls to identify a potential buffer to these effects. Drawing from self-determination theory, we examine how an employee's intrinsic motivation for citizenship may lessen the deleterious consequences of helping pressure at work. In two studies (a within-individual experience-sampling study and a two-wave between-individual study), we find consistent evidence that helping pressure has a positive indirect relationship with deviant behavior through increased negative affect. Further, we find evidence that intrinsic motivation for citizenship weakens the positive relationship of helping pressure with negative affect, buffering the indirect effect on subsequent deviant behavior. Theoretical and practical implications of these findings for the study of helping pressure at work are discussed.  相似文献
