Contingent Reinforcement Effects on Movement Responses of Prison Inmates to the Holtzman Inkblot Technique

Prison inmates were administered the Holtzman Inkblot Technique (HIT) under conditions of either verbal or nonverbal reinforcement of movement responses. Overall, there were no differences among the verbal, nonverbal, and control groups. Inmates charged with violent crimes were found to give the fewest movement responses. With crime category controlled, more movement responses were given under nonverbal conditions. There were no sex differences for movement responses but testing time increased significantly when administered by the female examiner.     

National Survey of Psychologists' Test Feedback Training,Supervision, and Practice: A Mixed Methods Study

In this empirical, mixed methods study, we explored test feedback training, supervision, and practice among psychologists, focusing specifically on how feedback is provided to clients and whether feedback skills are taught in graduate programs. Based on a 48.5% return rate, this national survey of clinical, counseling, and school psychologists' suggests psychologists provide test feedback to clients but inconsistently. Most respondents, 91.7%, indicated they give verbal feedback at least some of the time, whereas 35% do so every time. However, 2.8% indicated they never give feedback. A negative correlation exists for clinical psychologists between years since graduation and providing verbal feedback. Of particular interest, approximately one third of respondents indicated predoctoral coursework, practica, and internship were of little-to-no help in preparing them to provide feedback. Also, feedback training in predoctoral coursework, practica, and internship was not correlated to actually providing feedback. There was, however, a significant correlation between postdoctoral training and providing feedback. Consistent with existing ethical exceptions, the most frequent reason for not providing feedback was using assessments in forensic settings. Individuals who indicated their training was not helpful cited “trial and error” and self-instruction as ways in which they learned feedback skills. We discuss implications and suggestions for feedback training, research, and practice.     

A range of kindness activities boost happiness

This experiment investigates the effects of a seven-day kindness activities intervention on changes in subjective happiness. The study was designed to test whether performing different types of kindness activities had differential effects on happiness. Our recent systematic review and meta-analysis of the psychological effects of kindness (Curry, et al. 2018) revealed that performing acts of kindness boosts happiness and well-being. However, we noted in that review that rarely had researchers specifically compared the effects of kindness to different recipients, such as to friends or to strangers. Thus in a single factorial design (n=683) we compare acts of kindness to strong social ties, weak social ties, novel acts of self kindness, and observing acts of kindness, against a no acts control group. The results indicate that performing kindness activities for seven days increases happiness. In addition, we report a positive correlation between the number of kind acts and increases in happiness. Neither effect differed across the experimental the groups, suggesting that kindness to strong ties, to weak ties, and to self, as well as observing acts of kindness, have equally positive effects on happiness.     

Structure and measurement of depression in youths: applying item response theory to clinical data

Our goals in this article were to use item response theory (IRT) to assess the relation of depressive symptoms to the underlying dimension of depression and to demonstrate how IRT-based measurement strategies can yield more reliable data about depression severity than conventional symptom counts. Participants were 3,403 children and adolescents from 12 contributing clinical and nonclinical samples; all participants had received the Kiddie Schedule of Affective Disorders and Schizophrenia for School-Aged Children. Results revealed that some symptoms reflected higher levels of depression and were more discriminating than others. Furthermore, use of IRT-based information about symptom severity and discriminability in the measurement of depression severity was shown to reduce measurement error and increase measurement fidelity.     

Sufficient conditions for the uniqueness of parameter estimates from binary-response data

The procedure of fitting parameterized models to experimental data is that of extremalizing a statistically meaningful scalar-valued vector function. The existence of multiple local extrema can greatly complicate the search for the global solution. Sufficient conditions for uniqueness of the parameter estimates are usually determined from the convexity of the criterion surface: the convexity properties are determined by the statistical criterion, the structure of the model, the underlying distribution, and the observations (data). In this paper, we seek the combinations of criteria, models, and distributions which yield sufficient conditions for unique parameter estimates regardless of the observed binary-response data values.Under mild sufficient conditions usually satisfied in practice, the Maximum Likelihood, Minimum Chi Square, and Minimum Transform Chi Square criteria are convex functions when the parameters appear linearly. These results are applied to equalvariance models of signal detection/recognition, sequential response, and additive learning models with implications on the experimental design. Unequal-variance models and models of discrete-sensory processing (rectilinear ROC curves) lead to nonconvex criteria for some observations (saddlepoints are demonstrated). Although convexity cannot be assured for these cases, the results suggest an efficient search procedure in a lower dimensional subspace to find global extrema. The extension of these results to more than two response levels is discussed.     

CHRISTIAN HUMANISM AND PSYCHOTHERAPY: A RESPONSE TO BERGIN'S ANTITHESES

Abstract. Secular and religious values of psychotherapists influence the process of psychotherapy. The psychologist Allen Bergin has pointed out several major antitheses between values of secular psychotherapists and their religiously oriented clients. The present essay is a response to Bergin's antitheses, on the one hand, and to humanistic psychology, on the other, from the point of view of a Christian humanism. Karl Rahner's theological anthropology is proposed as one possible foundation for an explicit articulation of the relationship between psychotherapy and religion, and as a means to address apparently divergent values of psychotherapists and religious believers.     

Human participants challenges in youth tobacco cessation research: researchers' perspectives

Recruiting adolescents into smoking cessation studies is challenging, particularly given institutional review board (IRB) requirements for research conducted with adolescents. This article provides a brief review of the federal regulations that apply to research conducted with adolescents, and describes researchers' experiences of seeking IRB approval for youth cessation research. Twenty-one researchers provided information. The most frequently reported difficulty involved obtaining parental consent. Solutions to commonly reported problems with obtaining IRB approval are also identified. Waivers of parental consent can facilitate recruitment of youths into studies; however, researchers must ensure that their protocols comply with federal regulations when requesting a waiver.
