We evaluated a unique procedure to establish compliance with instructions in four young children diagnosed with autism spectrum disorder (ASD) who had low levels of compliance. Our procedure included methods to establish a novel therapist as a source of positive reinforcement, reliably evoke orienting responses to the therapist, increase the number of exposures to instruction–compliance–reinforcer contingencies, and minimize the number of exposures to instruction–noncompliance–no reinforcer contingencies. We further alternated between instructions with a high probability of compliance (high‐p instructions) with instructions that had a prior low probability of compliance (low‐p instructions) as soon as low‐p instructions lost stimulus control. The intervention is discussed in relation to the conditions necessary for the development of stimulus control and as an example of a variation of translational research. 相似文献

The authors explored how trunk compensation and hand symmetry in stroke survivors and healthy controls were affected by the distance and height of virtual targets during a bimanual reaching task. Participants were asked to reach to 4 different virtual targets set at: 90% of their arm length at shoulder, xiphoid process, and knee height, and 50% of their arm length at xiphoid process height. For the stroke group, for all targets, the hands’ movements were more asymmetrical than those of the healthy group, with more asymmetry observed in the direction of gravity, and trunk forward displacement values were larger and more variable. The knee targets had the largest trunk displacement values; index of curvature and trunk displacement were strongly correlated with participants’ impairment scores. A strong correlation was found between the hands’ asymmetry in the anterior or posterior direction for the shoulder targets, and the impairment scores. The results suggest that target height influences the degree of trunk compensation and hand symmetry during bimanual reaching by hemiparetic participants. 相似文献

Rape Myth Acceptance in Sexually Assaulted Adolescents' School Contexts: Associations with Depressed Mood and Alcohol Use 下载免费PDF全文

High school students exposed to sexual assault (SA) are at risk for negative outcomes like depressed mood and high‐risk drinking. Although evidence suggests that both social contexts and internalized stigma can affect recovery from SA, no research to date has directly examined the presence of stigma in social contexts such as high schools as a correlate of adjustment after SA. In this study, the self‐reported rape myth acceptance (RMA) of 3080 students from 97 grade cohorts in 25 high schools was used to calculate grade‐mean and school‐mean RMA, which was entered into multilevel models predicting depressed mood and alcohol use among N = 263 SA survivors within those schools. Two forms of RMA were assessed (i.e., rape denial and traditional gender expectations). Results indicate that higher grade‐mean rape denial was associated with higher risk for depressed mood among high school boys and girls exposed to SA, and higher grade‐mean traditional gender expectations were associated with higher risk for alcohol use among girls exposed to SA. Survivors' own RMA and school‐level RMA were not significantly associated with their depressed mood or alcohol use. Although causality cannot be concluded, these findings suggest that interventions that reduce stigma in social contexts should be explored further as a strategy to improve well‐being among high‐school‐aged survivors of SA. 相似文献

Parent training (PT) delivered as a guided self-help intervention may be a cost- and time-effective intervention in the treatment of children with externalizing disorders. In face-to-face PT, parenting strategies have repeatedly been identified as mediating mechanisms for the decrease of children’s problem behavior. Few studies have examined possible mediating effects in guided self-help interventions for parents. The present study aimed to investigate possible mediating variables of a behaviorally oriented guided self-help program for parents of children with externalizing problems compared to a nondirective intervention in a clinical sample. A sample of 110 parents of children with externalizing disorders (80 % boys) were randomized to either a behaviorally oriented or a nondirective guided self-help program. Four putative mediating variables were examined simultaneously in a multiple mediation model using structural equation modelling. The outcomes were child symptoms of ADHD and ODD as well as child externalizing problems, assessed at posttreatment. Analyses showed a significant indirect effect for dysfunctional parental attributions in favor of the group receiving the behavioral program, and significant effects of the behavioral program on positive and negative parenting and parental self-efficacy, compared to the nondirective intervention. Our results indicate that a decrease of dysfunctional parental attributions leads to a decrease of child externalizing problems when parents take part in a behaviorally oriented guided self-help program. However, none of the putative mediating variables could explain the decrease in child externalizing behavior problems in the nondirective group. A change in dysfunctional parental attributions should be considered as a possible mediator in the context of PT. 相似文献

In addressing the call for research to understand affect in sales, this research uses moral affect theory and literature on emotional contagion to examine the effects of salesperson gratitude and customer gratitude on downstream relationship outcomes. The findings of this work suggest that salesperson prosocial behaviors account for the positive association between salesperson gratitude and customer gratitude. These prosocial behaviors – information sharing and extra-role behaviors – combined with customer gratitude serve as explanatory mechanisms for the positive effects of salesperson gratitude on customer commitment, which is an important result of buyer-seller interactions and an essential component of long-term relationships. Further, this research finds that salesperson extra-role behaviors and relationship length interact such that salesperson extra-role behaviors cultivate customer gratitude within developing and established relationships, but that these behaviors are particularly beneficial for less mature relationships. Understanding the role of salesperson gratitude and customer gratitude in driving relational outcomes contributes to both a theoretical understanding of the role of affect in sales and practical applications of emotions within buyer-seller relationships. 相似文献

Women's responses to stereotypical media portrayals: An fMRI study of sexualized and domestic images of women 下载免费PDF全文
I. Stephanie Vezich Benjamin C. Gunter Matthew D. Lieberman 《Journal of Consumer Behaviour》2017,16(4):322-331
Women tend to be portrayed in a sexualized or domestic manner in mainstream advertising; importantly this trend holds not only for ads targeting men but also for those targeting women themselves. Such a focus on sexualized portrayals in particular may not seem strategic given a wealth of evidence suggesting that women evaluate these portrayals quite negatively. Consumer attitudes toward domestic portrayals are more mixed but, unsurprisingly, vary according to how much a woman identifies as traditional. If female consumers do not evaluate these common portrayals positively, why might they persist? Past work suggests a disconnect between reported attitudes toward general visual sexual stimuli and physiological and neural responses; therefore, it is plausible that neural responses to stereotypical female portrayals in advertising may be at odds with reported attitudes and may have a bigger impact on consumer behavior. The current study exposed women to sexualized, domestic, and control images in a functional magnetic resonance imaging scanner as an initial test of this idea. We found that participants reported liking both domestic and control images more than sexualized images. In contrast, they showed more activity in regions associated with reward and arousal (ventral striatum and amygdala, respectively) while viewing sexualized images relative to both control and domestic images. Surprisingly, ventral striatum response to sexualized ads was stronger for women who endorsed traditional attitudes than those who reported less traditional attitudes. These results suggest that despite reporting negative attitudes toward sexualized portrayals, women may in fact have a favorable response to these images.

Operant conditioning with Betta splendens (Bettas) has been investigated extensively using males of the species. Ethological studies of female Bettas have revealed aggressive interactions that qualitatively parallel those between male Bettas. Given these similarities, four experiments were conducted with female Bettas to examine the generality of a widely reported finding with males: mirror-image reinforcement. Swimming through a ring was reinforced by a 10-s mirror presentation. As with males, ring swimming was acquired and maintained when mirror presentations were immediate (Experiments 1, 2, and 3) and delayed (Experiment 4). The failure of conventional extinction (Experiments 1 and 2) and response-independent mirror presentations (Experiment 3) to maintain responding confirmed the reinforcing properties of mirror presentation. These results extend previous findings of mirror images as reinforcers in males of the same species and illustrate a complementarity between behavioral ecology and the experimental analysis of behavior. 相似文献

This study examined how rumors originating in 3- to 6-year-olds' causal inferences can affect their own and their peers' memories for a personally experienced event. This was accomplished by exposing some members of classrooms to contextual clues that were designed to induce inferences about the causes of two unresolved components of the event. After a 1-week delay, a substantial number of children who were exposed to the clues misremembered their inferences as actual experiences. Causal inferential memory errors were most pronounced among 5- and 6-year-olds. Also, many of the children whose classmates were exposed to the clues mistakenly incorporated their classmates' causal inferences into their own accounts, with 3- and 4-year-olds being most likely to make this error. 相似文献

Coping with spousal loss: potential buffering effects of self-reported helping behavior 总被引:1,自引:0,他引:1
The present study examined the role of self-reported helping behavior in attenuating the helper's depression following spousal loss. Using archival data from the Changing Lives of Older Couples sample (N = 289), the study shows that among bereaved participants who had experienced high loss-related grief, helping behavior (providing instrumental support to others) was associated with an accelerated decline in depressive symptoms for the helper from 6 months to 18 months following spousal loss. This relationship between giving help and recovery from depression was independent of support received, as well as measured health, and interpersonal and demographic factors. Implications of these results for theoretical approaches to the study of close relationships and well-being are discussed. 相似文献
