Gender effects in gaming research: a case for regression residuals?

Numerous recent studies have examined the impact of video gaming on various dependent variables, including the players' affective reactions, positive as well as detrimental cognitive effects, and real-world aggression. These target variables are typically analyzed as a function of game characteristics and player attributes-especially gender. However, findings on the uneven distribution of gaming experience between males and females, on the one hand, and the effect of gaming experience on several target variables, on the other hand, point at a possible confound when gaming experiments are analyzed with a standard analysis of variance. This study uses simulated data to exemplify analysis of regression residuals as a potentially beneficial data analysis strategy for such datasets. As the actual impact of gaming experience on each of the various dependent variables differs, the ultimate benefits of analysis of regression residuals entirely depend on the research question, but it offers a powerful statistical approach to video game research whenever gaming experience is a confounding factor.     

Investigating merger: subliminal psychodynamic activation and oneness motivation research

Two programs of empirical research have endeavored to explicate some of the unconscious processes involved in adult phenomena of merger, symbiosis, or oneness. Starting in the 1960s under the leadership of Lloyd Silverman (see, e.g., Silverman, Lachmann, and Milich 1982), subliminal psychodynamic activation (SPA) has used subliminal methods to prime and manipulate these processes. Later research into what was termed oneness motivation (OM) posited the existence of a chronic personality variable and explored it independently of priming (see, e.g., Siegel and Weinberger 1998). These lines of research have established links between unconscious processes of oneness and a range of clinical and nonclinical outcomes.     

Short-Term Psychodynamic Psychotherapy for personality disorders: a critical review of randomized controlled trials

The research evidence for Short-Term Psychodynamic Psychotherapy (STPP) in the treatment of personality disorders (PD) was examined through consideration of studies utilizing randomized controlled designs. An extensive literature search revealed eight published Randomized Controlled Trials (RCT) of moderate study quality. A critical review of this literature is offered to provide an evidence-based guidance for clinicians and implications for treatments are discussed. Preliminary conclusions suggest STPP may be considered an efficacious empirically-supported treatment option for a range of PDs, producing significant and medium to long-term improvements for a large percentage of patients. Further research is recommended to allow comparisons with alternative evidence-based approaches.     

Extensions of a versatile randomization test for assessing single-case intervention effects

The purpose of the present study was to investigate the statistical properties of two extensions of the Levin-Wampold (1999) single-case simultaneous start-point model's comparative effectiveness randomization test. The two extensions were (a) adapting the test to situations where there are more than two different intervention conditions and (b) examining the test's performance in classroom-based intervention situations, where the number of time periods (and associated outcome observations) is much smaller than in the contexts for which the test was originally developed. Various Monte Carlo sampling situations were investigated, including from one to five participant blocks per condition and differing numbers of time periods, potential intervention start points, degrees of within-phase autocorrelation, and effect sizes. For all situations, it was found that the Type I error probability of the randomization test was maintained at an acceptable level. With a few notable exceptions, respectable power was observed only in situations where the numbers of observations and potential intervention start points were relatively large, effect sizes were large, and the degree of within-phase autocorrelation was relatively low. It was concluded that the comparative effectiveness randomization test, with its desirable internal validity and statistical-conclusion validity features, is a versatile analytic tool that can be incorporated into a variety of single-case school psychology intervention research situations.     

Spirituality and Religiosity in Urban Adolescents with Asthma

Predictors of multiple dimensions of spirituality/religiosity (S/R) and adolescents’ preferences for having S/R (e.g., prayer) addressed in hypothetical medical settings were assessed in a sample of urban adolescents with asthma. Of the 151 adolescents (mean age = 15.8, 60% female, 85% African-American), 81% said that they were religious and spiritual, 58% attended religious services in the past month, and 49% prayed daily. In multivariable models, African-American race/ethnicity and having a religious preference were associated with higher levels of S/R (R ² = 0.07–0.25, P < .05). Adolescents’ preferences for including S/R in the medical setting increased with the severity of the clinical situation (P < .05).     

Seeing mind in action

Much recent work on social cognition and empathy in philosophy of mind and cognitive science has been guided by the assumption that minds are composed of intracranial phenomena, perceptually inaccessible and thus unobservable to everyone but their owners. I challenge this claim. I defend the view that at least some mental states and processes??or at least some parts of some mental states and processes??are at times visible, capable of being directly perceived by others. I further argue that, despite its initial implausibility, this view receives robust support from several strands of empirical research.     

The six most essential questions in psychiatric diagnosis: a pluralogue part 3: issues of utility and alternative approaches in psychiatric diagnosis

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM ?C whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part 1 of this article took up the first two questions. Part 2 took up the second two questions. Part 3 now deals with Questions 5 & 6. Question 5 confronts the issue of utility, whether the manual design of DSM-III and IV favors clinicians or researchers, and what that means for DSM-5. Our final question, Question 6, takes up a concluding issue, whether the acknowledged problems with the earlier DSMs warrants a significant overhaul of DSM-5 and future manuals. As in Parts 1 & 2 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.     

The six most essential questions in psychiatric diagnosis: a pluralogue. Part 4: general conclusion

In the conclusion to this multi-part article I first review the discussions carried out around the six essential questions in psychiatric diagnosis – the position taken by Allen Frances on each question, the commentaries on the respective question along with Frances’ responses to the commentaries, and my own view of the multiple discussions. In this review I emphasize that the core question is the first – what is the nature of psychiatric illness – and that in some manner all further questions follow from the first. Following this review I attempt to move the discussion forward, addressing the first question from the perspectives of natural kind analysis and complexity analysis. This reflection leads toward a view of psychiatric disorders – and future nosologies – as far more complex and uncertain than we have imagined.     

Doing Good, Feeling Good, and Having More: Resources Mediate the Health Benefits of Altruism Differently for Males and Females with Lumbar Spine Disorders

We evaluated whether resources mediate and/or moderate the relationship between altruism and health outcomes in adults with lumbar spine disorders. Hierarchical regression modeling on 243 persons with lumbar spine disorders evaluated gender differences and whether physical, emotional, and economic resources mediated or moderated the relationship between altruism (Schwartz Altruism) and health (Rand-36, PROMIS Pain Impact). Men and women had similar altruism subscale scores, but there were gender differences in the altruism-health relationships. Both men and women had better mental health with higher levels of Community Connection, after adjusting for Community Pressure, and this effect was mediated by emotional resources. Women evidenced better physical health and less pain impact when they endorsed higher levels of Community Connection and/or General Helping aspects of altruism. Physical and economic resources partially but did not fully mediate women??s altruism-physical health link. The altruism-pain impact link was not significant after adjusting for covariates. Men and women report similar levels of altruism but enjoy different benefits. Emotional resources explained the altruism-mental health link in both genders, but women experienced a physical health benefit of altruism that was not mediated by resources. Future research should test causal relationships.
