Effects of shifts in food reinforcement context on rats’ consumption of concurrently available water or sucrose solution 下载免费PDF全文
Chad M. Galuska Leslie E. Sawyer 《Journal of the experimental analysis of behavior》2017,107(1):85-100
The purpose of this study was to investigate the effects of signaled transitions from relatively rich to lean conditions of food reinforcement on drinking concurrently available water or sucrose‐sweetened water in rats. Past research demonstrated that these negative incentive shifts produce behavioral disruption in the form of extended pausing on fixed‐ratio schedules. Four male Long‐Evans rats operated on a two‐component multiple fixed‐ratio fixed‐ratio schedule. In one manipulation, the ratio was held constant and the components arranged either a large six‐pellet reinforcer (rich) or small one‐pellet reinforcer (lean). In a second manipulation, the components both produced a one‐pellet reinforcer but differed in terms of the ratio requirement, with the rich and lean conditions corresponding to relatively small and large ratios. In both manipulations, components were pseudorandomly presented to arrange four transitions signaled by retractable levers: lean‐to‐lean, lean‐to‐rich, rich‐to‐rich, and rich‐to‐lean (the negative incentive shift). During experimental conditions, a bottle with lickometer was inserted in the chamber, providing concurrent access either to tap water or a 10% sucrose solution. The negative incentive shift produced considerably more drinking than the other transitions in all rats during both manipulations. The level of drinking was not polydipsic; rather, it appears that the negative incentive shift enhanced the value of concurrently available reinforcers relative to food reinforcement. 相似文献

Purpose
The present study examined the moderating effects of family-supportive supervisor behaviors (FSSB) on the relationship between two types of workplace aggression (i.e., patient-initiated physical aggression and coworker-initiated psychological aggression) and employee well-being and work outcomes.Methodology
Data were obtained from a field sample of 417 healthcare workers in two psychiatric hospitals. Hypotheses were tested using moderated multiple regression analyses.Findings
Psychiatric care providers’ perceptions of FSSB moderated the relationship between patient-initiated physical aggression and physical symptoms, exhaustion and cynicism. In addition, FSSB moderated the relationship between coworker-initiated psychological aggression and physical symptoms and turnover intentions.Implications
Based on our findings, family-supportive supervision is a plausible boundary condition for the relationship between workplace aggression and well-being and work outcomes. This study suggests that, in addition to directly addressing aggression prevention and reduction, family-supportive supervision is a trainable resource that healthcare organizations should facilitate to improve employee work and well-being in settings with high workplace aggression.Originality
This is the first study to examine the role of FSSB in influencing the relationship between two forms of workplace aggression: patient-initiated physical and coworker-initiated psychological aggression and employee outcomes.173.

The Difficulties in Emotion Regulation Scale (DERS; Gratz & Roemer in Journal of Psychopathology and Behavioral Assessment, 26, 41–54, 2004) is a widely used measure of emotion regulation, however, few studies have examined the scale’s psychometric properties in clinical samples. The current study examined the latent factor structure of the scale, in addition to other psychometric properties, in a naturalistic sample of adult outpatients (n = 344) receiving dialectical behavior therapy (DBT). A number of models were fitted, including a bifactor model, which has not previously been examined with the DERS, but which may be more appropriate for addressing the study’s two primary aims. These aims were to: (1) investigate some of the prior concerns raised about the Awareness subscale items; and (2) evaluate the appropriateness of using DERS total vs. subscale scores. Results indicated that a modified bifactor model which excluded the Awareness items from the general factor fit the data best. Additional findings suggested that the DERS total score (excluding Awareness items) was reliable and had good criterion-related validity in this sample. However, the findings related to the DERS subscales were mixed. This study extends prior research on the DERS by demonstrating the utility of the scale with individuals receiving DBT for problems with emotion regulation, as well as by clarifying some of the prior questions about the scale’s latent structure. 相似文献

Over the past 30 years, technology has been introduced into higher education shifting the ways in which learning and student engagement occurs. While the literature suggests that technology offers benefits for improving educational outcomes, few studies have examined how benefits are achieved. This case study presents how the students and instructor of a course on postmodern theory and family therapy developed a praxis-based approach using a digital platform to improve pedagogy. Specifically, using a reflective approach based on ethnomethodology, this paper presents how the members of this course achieved a transformative generative dialogue using an online, simultaneous multi-user document, file-sharing and editing platform. This paper stresses the importance of all members of a course participating in the use of an interactive technological platform to facilitate open dialogue and collaboration. 相似文献

The present study investigated the relationship between the social psychological climate and sport commitment on both the individual and team level. High school athletes (n = 400) competing on 27 different teams completed motivational climate, caring climate, and sport commitment measures. Multilevel models were constructed to examine the hierarchical relationship between the climates and commitment. Task-involving (γ20 =.15, t = 2.31, p =.02) and caring climates (γ10 =.33, t = 3.48, p =.002) were significantly related to commitment on the individual level, and a task-involving climate (γ02 = 1.13, t = 2.90, p =.008) was significantly related to commitment on the team level. In an effort to enhance commitment, coaches and sport psychology consultants may wish to employ strategies targeted toward the facilitation of task-involving and caring climates. 相似文献

In general, people judge their chance of experiencing a health risk as being less than the general base rate because of their favorable status on risk factors (e.g., history of stroke). Presenting base rates for high and low risk groups (conditional base rates) were hypothesized to lessen people's tendency to adjust downward from the base rate because risk factors are included in conditional base rates (CBRs). Young (M= 19 years) and older women (M= 46 years) were presented with either a general base rate (GBR) or CBRs for high‐ and low‐risk groups for 5 health risks. The CBR groups were significantly less likely to adjust their probability judgments from the base rate for the risk group that they believed applied to them (e.g., smoker vs. nonsmoker). The CBR effect was replicated in a second experiment in which women (M = 19 years) were informed of either a GBR, a CBR for a high‐risk group, or a CBR for a low‐risk group. The findings suggest that people might estimate subjective probabilities by considering both the base rate for a health risk and self‐assessments on risk factors. Biases about one's status on risk factors, however, may limit people's identification with relevant risk groups and warrant further investigation. 相似文献

The role of African American skin color in hiring decisions was investigated in a 2 × 2 × 2 (Participant Sex × Applicant Sex × Applicant Skin Color) design. College‐age participants (N= 107) were presented with stimuli and asked to make 8 employment‐related decisions. An interaction of applicant skin color and participant sex and a skin‐color main effect were predicted. Fair‐skinned applicants were expected to receive better ratings from men, while dark‐skinned applicants were expected to receive better ratings from women or ratings from women would not differ. Additionally, in general, fair‐skinned individuals were expected to receive better ratings than dark‐skinned individuals. The results were consistent with the hypotheses. Results are discussed in terms of the “what is beautiful is good” stereotype and prior research. 相似文献

We present a discussion of some of the lessons the investigators learned during the development and implementation phases of the Parents Matter! Program (PMP). Lessons were learned that are relevant to various groups involved in large scale, multi-site, community-based intervention studies: investigators, community leaders, community members, project staff, and participants. Specific lessons learned include: (1) forge collaboration early: (2) maintain communication; (3) clearly delineate policies and procedures; and (4) develop proactive strategies. We also include a list of important questions to consider when contemplating similar projects. 相似文献

This article discusses five interrelated conceptions of dialogue in the works of Russian scholar Mikhail Bakhtin that ground relational dialectics theory: (a) dialogue as constitutive process, (b) dialogue as dialectical flux, (c) dialogue as aesthetic moment, (d) dialogue as utterance, and (e) dialogue as critical sensibility. The author's recent research in relational dialectics is discussed, as are directions for future research. Relational dialectics is positioned as a sensitizing theory different from systems theory and other dialectically oriented approaches. 相似文献
