Laboratory studies suggest that witnessing virtuous acts triggers moral elevation, an emotion characterized by feeling uplifted and increased prosocial motives. However, it remains unknown whether regular inductions can increase elevation and prosocial motives in daily life without being vulnerable to habituation or adaptation effects. Participants (total N = 181) were randomly assigned to elevating vs. neutral or amusing inductions (video or recall tasks) for seven days (Study 1), ten days (Study 2), or 12 days over one month (Study 3). Multilevel growth models showed that relative to comparison conditions, elevation inductions increased daily elevation, positive affect, and prosocial outcomes (compassionate goals and affiliation), and decreased self-protective motives (self-image goals). Adaptation effects occurred for immediate responses when exercises occurred daily, but not when spaced out over time, and not for outcomes measured later each day. Results suggest benefits of brief, regular elevation experiences and have implications for interventions targeting specific emotions. 相似文献

The goal of this study was to characterize the contribution of a population of low-threshold mechanoreceptors to short-term habituation of siphon-elicited reflex responses in Aplysia californica. Since the location of their somata is unknown, we refer to them as the Unidentified Low-Threshold mechanoreceptors (ULTs). The ULTs operate in parallel to the higher-threshold and well-characterized LE sensory neurons, yet little is known regarding their contribution to behavioral plasticity. Using extracellular recordings from the siphon nerve, we found that habituation training that favors ULT activation resulted in a significant decrease in afferent activity at training intervals up to 1 min per stimulus (1 min ISI). To determine how this reduction impacts responses at other sites of the reflex network, we used intracellular recordings to measure training-induced changes in either L29 excitatory interneurons or LFS siphon motor neurons. With a 30s ISI, changes at both locations were training site-specific and matched the rate of change of afferent activity, implicating regulated sensory activity as a primary mechanism. With a shorter training interval (1s ISI), site-specificity of training was not observed in the L29s, but was still preserved in the motor neurons. For both, the rate of change during training was faster than the rate of change of afferent activity. Taken together, we conclude that regulation of low-threshold sensory neuron activity can play a significant role in short-term habituation, but other network processes may be recruited at more rapid training intervals. 相似文献

Association Between Employment and Sexual Risk-Taking Behaviors Among Public High School Adolescents
We examined the relationship between adolescent after school and weekend employment and sexual intercourse behavior in a cross-sectional sample of public high school students in South Carolina. The CDC Youth Risk Behavior Survey was used to secure usable data from 4,800 subjects. Thirty-nine percent of the sample worked at a job for pay during the academic year of the study. The majority of all race/gender groups reported having sexual intercourse in their lifetime and during the past 3 months prior, with the exception of Caucasian females. For Caucasian males employment ranging from 1-5 to 31+ hours per week was associated with sexual risk-taking. Caucasian female employment was associated with sexual risk-taking at 16-20 and 21-25 hours of work per week. For African American males, the relationship between employment and sexual risk-taking was evidenced at the 1-5 and 26-30 hours of work per week levels. Similar trends were determined for Caucasians (males and females) regarding sexual intercourse in the past 3 months prior and working for pay during the academic year. Youth working above 10 hours per week during high school may have an increased risk for unintended pregnancy and sexually transmitted infections, including HIV. 相似文献

This proof-of-concept study tests the initial efficacy of the Building a Strong Identity and Coping Skills (BaSICS) intervention, a selective prevention of internalizing problems program for early adolescents exposed to high levels of poverty-related stress. Eighty-four early adolescents (Mage = 11.36 years) residing in very low-income neighborhoods were randomized to receive the 16-session intervention (n = 44) or to an assessment-only control condition (n = 40). BaSICS teaches coping skills, social identity development, and collective social action to empower youth with the ability to connect with members of their communities and cope with poverty-related stress in positive and collaborative ways. Pretest–posttest analyses showed that intervention adolescents acquired problem-solving and cognitive-restructuring skills and reduced their reliance on avoidant coping. In addition, HPA reactivity was significantly reduced in the intervention youth, but not controls. Finally, intervention youth's internalizing and somatic symptoms as reported by both youth and their parents, showed significant reductions over time, whereas control youth had no such changes. Results provide strong support for this approach to strength-building and symptom reduction in a population of early adolescents exposed to poverty-related stress. 相似文献

Backward chains are widely used to teach complex skills to individuals with developmental disabilities. Implementation of chaining procedures may vary regarding untaught steps and there is little to guide practitioners in the selection of chaining procedures. Moreover, there is a dearth of research evaluating effectiveness and efficiency of procedural variations of behavior chains. The purpose of this study was to extend previous research by evaluating the effectiveness, efficiency, and preference for four procedural variations (i.e., teacher‐completion, participant‐completion, no‐completion, and a control condition) of backward chains across vocational tasks with adults with developmental disabilities. Although procedural variations effectively established vocational skills, the participant‐completion procedure (in which the instructor implemented a least‐to‐most prompt hierarchy during all untrained steps in the chain) was the most efficacious backward chaining procedural variation and efficient in terms of sessions to mastery. The no‐completion procedure (in which the instructor completed all untrained steps in the chain out of view of the participant) was least efficient across trials, sessions, errors, and total duration to mastery. One participant preferred the no‐completion condition while the other two participants showed an initial preference for the teacher‐completion condition that changed to preference for the no‐completion condition. Vocational skills maintained 1‐ and 4‐weeks postmastery. Stakeholders rated goals, procedures, and outcomes as socially valid. 相似文献

Violent rhetoric online is becoming increasingly relevant to the practice of forensic mental health assessment as examinee's virtual lives may transform into real-world acts of violence. With the rise of a diverse subculture of violent online communities, the aim of the present study was to inform how concerns with online sources of collateral data and racial/ethnic biases may influence determinations of violence potential. Using an experimental design, jury-eligible participants (N = 278) and forensic mental health experts (N = 78) were presented with mock Twitter (now referred to as X) posts that varied by data source (i.e., how information was accessed) and the examinee's race/ethnicity. Results showed no differences in participants' ratings of data credibility, how much weight they would place on the posts in a threat assessment, or how likely the examinee was to act violently against his intended target. Implications regarding the interpretation of social media evidence, relevant limitations, and future research are discussed. 相似文献

Profiles of externalizing behavior problems for boys and girls across preschool: the roles of emotion regulation and inattention 总被引:1,自引:0,他引:1
Although externalizing behavior typically peaks in toddlerhood and decreases by school entry, some children do not show this normative decline. A sample of 383 boys and girls was assessed at ages 2, 4, and 5 for externalizing behavior and at age 2 on measures of emotion regulation and inattention. A longitudinal latent profile analysis was performed and resulted in 4 longitudinal profiles of externalizing behavior for each gender. Poor emotion regulation and inattention were important predictors of membership in the chronic-clinical profile for girls, whereas socioeconomic status and inattention were important predictors of membership in the chronic-clinical profile for boys. Results are discussed with respect to the development of adaptive skills that lead to normative declines in externalizing behavior across childhood. 相似文献

When two masked, to-be-attended targets are presented within approximately half a second of each other, performance on the second target (T2) suffers, relative to when the targets are presented further apart in time or when the first target (T1) can be ignored. This pattern of results is known as the attentional blink (AB). Typically, participants differ with respect to the magnitude of their AB and their overall target accuracy. Despite investigations as to what participant characteristics may influence AB performance (e.g., age, brain damage, or mood state), there has been no focused examination of whether individual differences in cognitive performance measures predict the magnitude of the AB or overall rapid serial visual presentation(RSVP) target accuracy. Our university studentparticipants performed single-target and dual-target RSVP tasks, as well as a selection of cognitive tasks that did not use RSVP presentations, with color, letter, digit, and object stimuli. Overall performance on each of the RSVP targets (T1, T2, and single target) was predicted by speeded manual and vocal identification times to isolated stimuli and by performance with other RSVP targets. However, the magnitude of the AB was predicted only by T1 accuracy, not by any other performance measures. The results suggest that individual differences in AB magnitude do not result from differences in effective RSVP target encoding and are not well explained by varied information-processing abilities. 相似文献
