COMPARING PLEASURE AND PAIN: THE FUNDAMENTAL MATHEMATICAL EQUIVALENCE OF REWARD GAIN AND SHOCK REDUCTION UNDER VARIABLE INTERVAL SCHEDULES

The relationship between positive and negative reinforcement and the symmetry of Thorndike's law of effect are unresolved issues in operant psychology. Here we show that, for a given pattern of responding on variable interval (VI) schedules with the same programmed rate of food rewards (positive reinforcement VI) or electric shocks (negative reinforcement VI), there is a fundamental mathematical equivalence between reward gain and shock reduction. We also provide the first normative account of how animals should respond on a negative VI schedule, showing that it is better to space responses evenly than to respond with a variable interresponse time (IRT). Published data from rats, however, indicate that these animals respond irregularly, often with a burst of activity immediately following a shock. While this is irrational in the experimental setting, it may represent an appropriate response to the heterogeneity of stimuli commonly encountered in natural environments. We discuss the broader implications of our analysis for understanding how animals evaluate appetitive and aversive stimuli.     

Educational Needs of Primary Care Physicians Regarding Direct-to-Consumer Genetic Testing

To assess the educational needs of North Carolina primary care physicians (PCPs) about direct-to-consumer (DTC) genetic testing, surveys were mailed to 2,402 family and internal medicine providers in North Carolina. Out of 382 respondents, 323 (85%) felt unprepared to answer patient questions and 282 (74%) reported wanting to learn about DTC genetic testing. A total of 148 (39%) were aware of DTC genetic testing. Among these, 63 (43%) thought DTC genetic testing was clinically useful. PCPs who felt either unprepared to answer patient questions (OR = 0.354, p = 0.01) or that DTC genetic testing was clinically useful (OR = 5.783, p = 0.00) were more likely to want to learn about DTC genetic testing. PCPs are interested in learning about DTC genetic testing, but are mostly unaware of DTC testing and feel unprepared to help patients with DTC testing results. Familiar and trusted channels that provide the information and tools PCPs need to help answer patient’s questions and manage their care should be used when creating educational programs.     

The Effects of Combining PETTLEP Imagery and Action Observation on Bicep Strength: A Single-Case Design

We investigated the effects of PETTLEP imagery combined with action observation on bicep curl performance. Using a single-case design, four participants completed a baseline phase followed by PETTLEP imagery with and without an observational aid. Results indicated that using an observational aid in conjunction with PETTLEP imagery can improve bicep curl performance, but not to a greater degree than PETTLEP imagery alone. This indicates that observational aids may not be an essential addition to imagery interventions. The study highlights further the benefit of using PETTLEP imagery for enhancing strength performance, which should be considered by practitioners delivering resistance training programs.     

Raising Our Game: The Necessity and Progression of Expertise-Based Training in Applied Sport Psychology

At present, training in applied sport psychology chiefly targets and accelerates professional competence. However, theory and evidence suggests that our clients would experience significant benefit if our training targeted and accelerated professional expertise rather than just competence. Specifically, we argue that expertise-based training can (a) help trainees to go on to break the “thinking ceiling” of competence; (b) foster a more independent, flexible, and creative form of practice; and (c) support a longer term and more practitioner-centered training philosophy. To deliver these benefits, we then conclude by outlining some key principles for the progression of expertise-based training in applied sport psychology.

Lay Summary: In light of the inconsistencies that still surround professional training in ASP, we discuss the merits that a more expertise-based agenda can bring to practitioners and, most important, our clients. We also discuss ways in which this agenda can be progressed to support an evidence-informed evolution of ASP training systems.     

Development of a Scale to Assess Knowledge about Suicide Postvention using Item Response Theory

Knowledge about suicide postvention (KSPV) is an important distal outcome in the evaluation of suicide prevention programs that focus on the bereaved. However, most scales are specifically tailored to the evaluation study in question and psychometric properties are often unsatisfactory. Therefore, we developed the KSPV scale. Scale properties were investigated with Rasch trees, a newly developed method in the framework of item response theory. Additionally, we provide cues for convergent validity. In summary, the scale shows satisfactory properties for assessing KSPV and could be used to evaluate suicide postvention programs more effectively.     

Creating space for interdisciplinary and interagency learning: the Newham ‘responsiveness’ days

Family therapists in Newham's specialist child and adolescent mental health services describe an interdisciplinary and interagency training day for Newham's children's workforce; the workshop aims to develop co‐learning about communication and collaboration in the context of a rapidly changing service environment, driven by current national and local policy initiatives. The training team attempts to generate a rich learning context using three themes: networking, responsiveness and complexity. The workshop demonstrates that it is perhaps possible to embed complex communication discourses in brief, pragmatic training, enhancing collaboration between professionals in local networks.
