This study replicated previous basic research into the dynamics of choice and extended this analysis to children's behavior in a naturalistic setting. Two preschoolers with disabilities were observed interacting with their teachers at baseline and during an experimental analysis involving four pairs of concurrent variable‐interval schedules of adult attention implemented by an experimenter. Each child was exposed to four experimental phases in which the relative reinforcer rates for on‐ and off‐task behavior were 10:1, 1:1, 1:10, and reversed back to 10:1. The 10:1 phase was designed to mimic the same schedules and types of adult attention observed at baseline. We used the generalized matching equation to model steady‐state behavior at the end of the transition phases and to evaluate changes in sensitivity at various points throughout the phases. Choice in transition was evaluated by plotting log behavior ratios by session, cumulated time on‐ and off‐task and cumulated attention for on‐ and off‐task behavior by session, and interreinforcer behavior ratios following different sequences of the first four reinforcer deliveries. The generalized matching equation accounted for a large proportion of variance in steady‐state responding, sensitivity values increased steadily throughout the phases, patterns of choice in transition were similar to those reported in basic research, and interreinforcer preference generally shifted toward the just‐reinforced alternative. These findings are consistent with previous basic research and support the generality of the dynamics of choice to children's on‐ and off‐task behavior reinforced by adult attention.  相似文献

Although the career benefits associated with professional networking are relatively well established, the repercussions of this highly regarded career management activity for voluntary turnover have rarely been examined. Given the potential costs associated with voluntary turnover, this study sought to clarify the roles of networking behaviors in relation to voluntary turnover by focusing on the distinction between internal and external networking. Based on survey responses of industrial and organizational psychology professionals, we found that internal and external networking behaviors differentially predicted decisions to voluntarily leave employers 2 years later: The likelihood of voluntary turnover was negatively predicted by internal networking and positively predicted by external networking. Furthermore, to shed light on the reasons why employee networking behaviors differentially predicted turnover decisions, this study also examined 4 turnover antecedents (job satisfaction, job embeddedness, perceived employment opportunities, and job offers) as potential mediating mechanisms. Results revealed that the relationships of internal and external networking with voluntary turnover were mediated by job embeddedness and job offers, respectively. We discuss the implications of these findings for understanding and managing employee networking and retention.  相似文献

The exploration of social networking sites (SNS) in promoting social change efforts offers great potential within the field of community psychology. Online communities on SNS provide opportunities for bridging across groups, thus fostering the exchange of novel ideas and practices. Currently, there have only been limited efforts to examine SNS within the context of youth‐led efforts. To explore the potential of SNS to facilitate the diffusion of social justice efforts between distinct youth groups, we linked three school‐based youth‐led participatory action research projects involving 54 high school students through a SNS. This study offers an innovative methodological approach and framework, utilizing social network analysis and strategic sampling of key student informants to investigate what individual behaviors and online network features predict student adoption of social change efforts. Findings highlight prospective facilitators and barriers to diffusion processes within a youth‐led online network, as well as key constructs that may inform future research. We conclude by providing suggestions for scholars and practitioners interested in examining how SNS can be used to enhance the diffusion of social justice strategies, youth‐led engagement efforts, and large‐scale civic organizing.  相似文献

The interpretation of emotionally ambiguous words, sentences, or scenarios can be altered through training procedures that are collectively called cognitive bias modification for interpretation (CBM-I). In three experiments, we systematically manipulated the nature of the training in order to discriminate between emotional priming and ambiguity resolution accounts of training effects. In Experiment 1 participants completed word fragments that were consistently related to either a negative or benign interpretation of an ambiguous sentence. In a subsequent semantic priming task they demonstrated an interpretation bias, in that they were faster to identify relatedness of targets that were associated with the training-congruent meaning of an emotionally ambiguous homograph. We then manipulated the training sentences to show that interpretation bias was eliminated when participants simply completed valenced word fragments following unrelated sentences (Experiment 2), or completed fragments that were related to emotional but unambiguous sentences (Experiment 3). Only when participants were required to actively resolve emotionally ambiguous sentences during training did changes in interpretation emerge at test. Findings suggest that CBM-I achieves its effects by altering a production rule that aids the selection of meaning from emotionally ambiguous alternatives, in line with an ambiguity resolution account.  相似文献

This study investigated attentional biases in children with asthma. The study aimed at testing whether children with asthma are vigilant to asthma and/or anxiety cues. Thirty-six children (18 with asthma and 18 healthy controls) aged 9–12 completed a computerised dot probe task designed to measure attentional bias to three different categories of words: asthma, anxiety symptom and general negative emotion. Main caregiver anxiety was also assessed, as was frequency of inhaler use for those with asthma. Children with asthma showed an attentional bias towards asthma words but not anxiety or general negative emotion words. Children without asthma showed no significant attentional biases to any word categories. Caregiver anxiety was correlated with asthma word attentional bias in the asthma group. The findings indicate that attentional bias is present in children with asthma. Further research is required to ascertain if this exacerbates or maintains health-related problems.  相似文献

This article overviews relational‐cultural theory and developmental relational counseling (DRC) and reports the results of a randomized study evaluating supervisory relational health as defined by DRC theoretical constructs. As measured by an adaptation of the Relational Health Index (Liang et al., 2002 ), counseling students enrolled in clinical courses identified clear preferences for supervisory relationships that promoted accurate relational awareness, compassion, clarity, feedback receptivity, and responsible use of power.  相似文献

Insomnia is a common feature among individuals with anxiety disorders. Studies of cognitive behavioral therapy (CBT) for anxiety report moderate effects on concomitant insomnia symptoms, but further research is still needed especially toward understanding how CBT for anxiety renders beneficial effects on insomnia. The current study examined changes in insomnia symptoms reported by 51 Veterans who participated in a group-based transdiagnostic CBT for anxiety intervention. In addition, insomnia symptoms were examined in relation to symptoms of general distress (GD), anhedonic depression (AD), and anxious arousal (AA) pre- to post-treatment. Results revealed a small, though statistically significant (p < .05) beneficial effect on insomnia symptoms. When changes in GD, AD, and AA were simultaneously examined in relation to changes in insomnia, change in AA was the only significant predictor of insomnia symptoms. The current study highlights the role of AA in the relationship between anxiety disorders and insomnia and demonstrates that reductions in insomnia during transdiagnostic CBT for anxiety can be largely attributed to changes in AA.  相似文献

There is considerable agreement among epistemologists that certain abilities are constitutive of understanding-why. These abilities include: constructing explanations, drawing conclusions, and answering questions. This agreement has led epistemologists to conclude that understanding is a kind of know-how. However, in this paper, I argue that the abilities constitutive of understanding are the same kind of cognitive abilities that we find in ordinary cases of knowledge-that and not the kind of practical abilities associated with know-how. I argue for this by disambiguating between different senses of abilities that are too often lumped together. As a consequence, non-reductionists about understanding—those that claim that understanding-why is not reducible to knowledge-that—need to find another way to motivate the view. In the end, the fact that abilities are constitutive of understanding-why does not give us reason to conclude that understanding is a kind of know-how.  相似文献

This study assessed the psychometric properties of a parent-reported tic severity measure, the Parent Tic Questionnaire (PTQ), and used the scale to establish guidelines for delineating clinically significant tic treatment response. Participants were 126 children ages 9 to 17 who participated in a randomized controlled trial of Comprehensive Behavioral Intervention for Tics (CBIT). Tic severity was assessed using the Yale Global Tic Severity Scale (YGTSS), Hopkins Motor/Vocal Tic Scale (HMVTS) and PTQ; positive treatment response was defined by a score of 1 (very much improved) or 2 (much improved) on the Clinical Global Impressions – Improvement (CGI-I) scale. Cronbach’s alpha and intraclass correlations (ICC) assessed internal consistency and test-retest reliability, with correlations evaluating validity. Receiver- and Quality-Receiver Operating Characteristic analyses assessed the efficiency of percent and raw-reduction cutoffs associated with positive treatment response. The PTQ demonstrated good internal consistency (α = 0.80 to 0.86), excellent test-retest reliability (ICC = .84 to .89), good convergent validity with the YGTSS and HM/VTS, and good discriminant validity from hyperactive, obsessive-compulsive, and externalizing (i.e., aggression and rule-breaking) symptoms. A 55% reduction and 10-point decrease in PTQ Total score were optimal for defining positive treatment response. Findings help standardize tic assessment and provide clinicians with greater clarity in determining clinically meaningful tic symptom change during treatment.  相似文献
