Resistance to change and the law of effect

Three experiments using multiple schedules of reinforcement explored the implications of resistance-to-change findings for the response-reinforcer relation described by the law of effect, using both steady-state responding and responding recorded in the first few sessions of conditions. In Experiment 1, when response-independent reinforcement was increased during a third component, response rate in Components 1 and 2 decreased. This response-rate reduction was proportionately greater in a component in which reinforcer magnitude was small (2-s access to wheat) than in the component in which it was large (6-s access to wheat). However, when reinforcer rates in the two components were varied together in Experiments 2 and 3, response-rate change was the same regardless of the magnitude of reinforcers used in the two components, so that sensitivity of response rates to reinforcer rates (Experiment 2) and of response-rate ratios to reinforcer-rate ratios (Experiment 3) was unaffected by the magnitude of the reinforcers. Therefore, the principles determining resistance to change, described by behavioral momentum theory, seem not to apply when the source of behavior change is the variation of reinforcement contingencies that maintain the behavior. The use of extinction as a manipulation to study resistance to change is questioned.     

White Racial Identity and Attitudes Toward People With Disabilities

This empirical study investigated the relationship between racial identity and attitudes toward people with disabilities. Results indicate that higher statuses of racial identity correlate positively while lower and more racist‐oriented statuses correlate negatively with attitudes toward people with disabilities. The study supports the notion that attitudes from cultural memberships associated with power can transfer from one domain (i.e., White/People of Color) to another domain (i.e., Abled/Disabled). Este estudio empírico investigó la relación entre la identidad y actitudes raciales hacia personas con incapacidades. Los resultados indican que las posiciones más altas de la identidad racial se pone en correlación positivamente mientras bajan y más posiciones racista‐orientados se pone en correlación negativamente con actitudes hacia personas con incapacidades. El estudio sostiene la noción que actitudes de asociaciones culturales asociadas con el poder pueden transferir de un dominio (es decir, los Blancos/Personas del Color) a otro dominio (es decir, Capacitados/Incapacitados).     

First-time mothers' expectations of parenthood: What happens when optimistic expectations are not matched by later experiences?

Becoming a parent is a major developmental transition of adulthood. Individuals often have optimistic expectations about parenthood, yet this transition also presents a number of challenges. The authors investigated whether new parents have overly optimistic expectations about parenthood and, if they do, how this influences their adjustment to this role. The sample consisted of 71 first-time mothers who completed questionnaires during pregnancy and at 4 months postpartum. The study assessed women's expectations of caring for their infant and the influence parenthood would have on their well-being and their relationships with others. Most women's expectations were matched or exceeded by their parenting experiences. However, where experiences were negative relative to expectations, there was greater depression symptomatology and poorer relationship adjustment.     

Internet-Delivered Targeted Group Intervention for Body Dissatisfaction and Disordered Eating in Adolescent Girls: A randomized controlled trial

This study evaluated a targeted intervention designed to alleviate body image and eating problems in adolescent girls that was delivered over the internet so as to increase access to the program. The program consisted of six, 90-minute weekly small group, synchronous on-line sessions and was facilitated by a therapist and manual. Participants were 73 girls (mean age=14.4 years, SD=1.48) who self-identified as having body image or eating problems and were randomly assigned to an intervention group (n=36) (assessed at baseline, post-intervention and at 2- and 6-months follow-up) or a delayed treatment control group (n=37) (assessed at baseline and 6–7 weeks later). Clinically significant improvements in body dissatisfaction, disordered eating, and depression were observed at post-intervention and maintained at follow-up. Internet delivery was enthusiastically endorsed. The program offers a promising approach to improve body image and eating problems that also addresses geographic access problems.     

How does thought suppression impact upon beliefs about uncontrollability of worry?

According to Wells’ metacognitive model of generalised anxiety disorder (GAD; [Wells, A. (1995). Meta-cognition and worry: A cognitive model of generalised anxiety disorder. Behavioural and Cognitive Psychotherapy, 23, 301–320]), GAD patients attempt to suppress intrusions that trigger worry. Wells postulates that these attempts are rarely effective and may increase the frequency of worry triggers. These apparent failures are interpreted as evidence for loss of mental control, thereby exacerbating beliefs about worry uncontrollability. The current study tested these predictions. Sixty-two high worriers completed a naturalistic experiment comprising two sessions separated by 1 week. In Session 1, participants recorded their beliefs about worry in general, including its uncontrollability. They then selected a current worry and recorded how often it came to mind over the following week. The Suppression group (N=32) suppressed their chosen worry during the week. The Mention group (N=30) simply monitored its occurrence. In Session 2, Session 1 measures were repeated. Contrary to prediction, the Suppression group reported a significant increase in worry controllability in general. No shift was demonstrated by the Mention group. In addition, relative to the Mention group, the Suppression group reported more success at suppressing their chosen worries, spent less time thinking about them, and found them more controllable and less distressing. Findings are discussed within the context of Wells’ model.     

Racial differences in sensitivity to behavioral integrity: attitudinal consequences, in-group effects, and "trickle down" among Black and non-Black employees

Recent research has suggested that employees are highly affected by perceptions of their managers' pattern of word-action consistency, which T. Simons (2002) called behavioral integrity (BI). The authors of the present study suggest that some employee racial groups may be more attentive to BI than others. They tested this notion using data from 1,944 employees working at 107 different hotels and found that Black employees rated their managers as demonstrating lower BI than did non-Black employees. Mediation analyses were consistent with the notion that these differences in perceived BI in turn account for cross-race differences in trust in management, interpersonal justice, commitment, satisfaction, and intent to stay. Results of hierarchical linear modeling were consistent with the idea that middle managers' perceptions of their senior managers' BI "trickle down" to affect line employee perceptions of the middle managers and that this trickle-down effect is stronger for Black employees. The authors interpret these results as indicative of heightened sensitivity to managers' BI on the part of Black employees. They also found a reverse in-group effect, in that Black employees were substantially more critical of Black managers than were non-Black employees.     

A temporal-specific and transient cAMP increase characterizes odorant classical conditioning

Increases in cyclic adenosine monophosphate (cAMP) are proposed to initiate learning in a wide variety of species. Here, we measure changes in cAMP in the olfactory bulb prior to, during, and following a classically conditioned odor preference trial in rat pups. Measurements were taken up to the point of maximal CREB phosphorylation in olfactory bulb mitral cells. Using both drug and natural unconditioned stimuli we found effective learning was associated with an increase in cAMP at the end of the conditioning trial, followed by a decrease 5 min later. This early timing of a transient cAMP increase occurred only when the odor was paired with an effective drug or natural unconditioned stimulus (US). The data support the hypothesis that the rate of adenylate cyclase activation is enhanced by pairing calcium and G-protein activation and that the timing of transient cAMP signaling is critical to the initiation of classical conditioning.     

Revised Provisional Diagnostic Profile: 2016

ABSTRACT

In Anna Freud’s and other previous versions of the diagnostic profile, drive theory and the structural model were the central organizing concepts. Though these are retained in the current version, greater emphasis has been made of other conceptual perspectives. In particular, the importance of understanding the impact of the child’s external world and the child’s attachment security; also the central importance of affects, both their recognition and management. These changes are seen in such sections as those on the ego which has been expanded to include a section on play and affects. The developmental line of anxiety and the concept of theory of mind have also been added.
