Identifying subgroups that succeed or fail with three levels of physical activity intervention: the Activity Counseling Trial.

The authors used recursive partitioning methods to identify combinations of baseline characteristics that predict 2-year physical activity success in each of 3 physical activity interventions delivered in the multisite Activity Counseling Trial. The sample consisted of 874 initially sedentary primary care patients, ages 35-75 years, who were at risk for cardiovascular disease. Predictors of 2-year success were specific to each intervention and represented a range of domains, including physiological, demographic, psychosocial, health-related, and environmental variables. The results indicate how specific patient subgroups (e.g., obese, unfit individuals; high-income individuals in stable health) may respond differently to varying levels and amounts of professional assistance and support. The methods used provide a practical first step toward identifying clinically meaningful patient subgroups for further systematic investigation.     

The effects of self‐explaining when learning with text or diagrams

Self‐explaining is an effective metacognitive strategy that can help learners develop deeper understanding of the material they study. This experiment explored if the format of material (i.e., text or diagrams) influences the self‐explanation effect. Twenty subjects were presented with information about the human circulatory system and prompted to self‐explain; 10 received this information in text and 10 in diagrams. Results showed that students given diagrams performed significantly better on post‐tests than students given text. Diagrams students also generated significantly more self‐explanations that text students. Furthermore, the benefits of self‐explaining were much greater in the diagrams condition. To discover why diagrams can promote the self‐explanation effect, results are interpreted with reference to the multiple differences in the semantic, cognitive and affective properties of the texts and diagrams studied.     

Reciprocal Relationships between Leader–Member Exchange (LMX) and Job Satisfaction: A Cross‐Lagged Analysis

While previous research has mainly emphasised the importance of leader–member exchange (LMX) to job satisfaction, there is a lack of research on reciprocal relationships between job satisfaction and LMX. In this study, we not only suggest that good LMX increases job satisfaction, but that job satisfaction can also enhance high‐quality supervisor–employee relationships. A full cross‐lagged panel analysis was used to test reciprocal relationships between LMX and job satisfaction. Employees (N= 279) of a large information technology company filled out questionnaires at two times, with a time lag of 3 months. In line with our predictions, findings revealed a positive relationship between LMX and job satisfaction both at Time 1 and Time 2. Moreover, LMX at Time 1 predicted the increase of job satisfaction at Time 2, and job satisfaction at Time 1 predicted the increase of LMX at Time 2. The results demonstrate the need to consider reciprocal relationships between job satisfaction and LMX when explaining employees' workplace outcomes. Our findings are discussed in terms of positive psychology theory.     

Pains and gains: a study of forced terminations

The forced termination of psychoanalysis, such as occurs when the analyst makes a geographic move, uniquely disrupts the analytic setting. This paper recounts the author's experience of terminating a full-time private practice of psychoanalysis and psychoanalytic therapy for such a move. The limited literature on the subject is reviewed with a focus on the use of technical variation in the forced termination situation. The author delineates three areas of interaction with patients where technical variation proved in her experience to be of value: dealing with countertransference and counter-reaction, providing information about the move, and the consideration and process of referral for continued therapy. As opposed to what would be predicted from a classical psychoanalytic perspective, the use of such technical maneuvers seemed to facilitate rather than impede analytic work. These variations in technique served at crucial times to maintain the analytic alliance, to preserve the patient's capacity to recognize and make use of transference, and to provide avenues for resolving past traumas in the transference and the actual loss of the analyst. The concept of the analyst as a new or useable object is proposed as providing a theoretical framework for understanding these observations.     

Perception of structure in novel music

Two experiments demonstrated the way in which musicians and nonmusicians process realistic music encountered for the first time. A set of tunes whose members were related to each other by a number of specific musical relationships was constructed. In Experiment 1, subjects gave similarity judgments of all pairs of tunes, which were analyzed by the ADDTREE clustering program. Musicians and nonmusicians gave essentially equivalent results: Tunes with different rhythms were rated as being very dissimilar, whereas tunes identical except for being in a major versus a minor mode were rated as being highly similar. In Experiment 2, subjects learned to identify the tunes, and their errors formed a confusion matrix. The matrix was submitted to a clustering analysis. Results from the two experiments corresponded better for the nonmusicians than for the musicians. Musicians presumably exceed nonmusicians in the ability to categorize music in multiple ways, but even nonmusicians extract considerable information from newly heard music.     

Police,courts, and corrections: Experiences of procedural injustice among Black adults

Racial disparities and a corresponding lack of trust have been documented within the criminal legal system. In response, criminal legal system actors have sought to strengthen the legitimacy of their agencies. However, legitimizing these agencies can be problematic. Some argue that the current criminal legal system continues the legacy of slavery and Jim Crow as Blacks are disproportionately policed and incarcerated. As a framework, procedural injustice can offer a unique backdrop and interrogate ways in which the criminal legal system engages in delegitimizing actions that provoke noncompliance and enable social control. Using a procedural injustice lens, this study examines how justice-involved Black adults experience mistreatment by justice system actors. Semistructured interviews were conducted with 84 Black adults in Newark and Cleveland. Study findings offer a comprehensive account of how participants experience procedural injustice as arrestees, defendants, and incarcerated persons. More specifically, participant narratives describe deliberately antagonistic, abusive, and dehumanizing treatment by justice-system agents—often depicted as racially motivated. Participant accounts also describe this mistreatment as occurring in a context of coercion and powerlessness and as being institutionally sanctioned. Implications for the preservation of racial hierarchies, research, practice, and community psychology are discussed.     

Vulnerable workers in insecure jobs: A critical meta-synthesis of qualitative findings

Job insecurity is a widespread workplace stressor that has been extensively investigated using quantitative approaches. With the use of a critical organisational psychology framework, we conducted a meta-synthesis of 20 qualitative studies to investigate the experience of job insecurity among vulnerable employee groups (i.e., women and immigrants). The qualitative meta-synthesis results suggest that there are meaningful differences. Specifically, whereas women were more concerned with and exposed to deteriorating working conditions, men experienced job insecurity as a threat to their identity. Among immigrants, the experience of job insecurity is viewed as largely intersecting with the legal system, impacting their ability to remain in their country and making them feel powerless. Thematic evidence also emerged regarding individual actions that participants use to attain security in contrast to corporate strategies that enhance job insecurity. We contribute to the critical organisational psychology literature by discussing how these results test common academic theories and neoliberal assumptions pervasive within the job insecurity literature: We highlight how organisations manufacture job insecurity, question the existence of harmonious social exchanges, discuss the use of job insecurity as a form of worker control, consider the role of the legal context in aiding worker exploitation and argue for an intersectional view of job insecurity.     

When the poor give more than the rich: The role of resource evaluability on relative giving

Five experiments examined the role of resource evaluability on giving. We systematically varied participants' resources they and another potential donor received and whether they could donate to a recipient either by themselves or with the other donor. Participants in the relative advantage condition received more resources than the other donor, and those in the relative disadvantage condition received fewer resources than the other donor. The presence of the other donor made participants' resources evaluable and shaped giving: Relatively disadvantaged participants were proportionally more generous than advantaged participants but only when they could evaluate their resources. Neither the mere presence of others nor reputational concerns could explain the results. Exploratory mediation and moderation analyses further showed that relatively disadvantaged participants give proportionally more the higher and the more equal they perceive their status to the advantaged donor. This shows that the generosity of those who have less does depend on how they evaluate their status compared to other donors. Our results provide insights into the question of why and when resource asymmetries between donors result in prosocial giving and can influence fundraising strategies of charitable organizations.     

Episodic memory effects of gamma frequency precuneus transcranial magnetic stimulation in Alzheimer's disease: A randomized multiple baseline study

Episodic memory decline is the prominent neuropsychological feature of typical Alzheimer's Disease (AD), for which current treatments have a limited clinical response. Recently, gamma entrainment therapy has been used as a non-invasive treatment in AD, providing evidence that it may have the potential to alleviate brain pathology and improve cognitive function in AD patients. At the same time, the precuneus (PC) has been recognized as a key area involved in AD related memory deficits and as a key node of the Default Mode Network. This study aimed to investigate the effectiveness of a 40 Hz Transcranial Magnetic Stimulation (TMS) intervention, delivered bilaterally to the precuneus for 10 days, in improving the patients' episodic memory performance. Secondary outcome variables investigated included general cognitive function, semantic and spatial memory, as well as attention and executive function. A concurrent multiple baseline design across five cases was employed. Four patients completed the study. Visual analysis combined with effect size indices were used to evaluate changes across phases. An increase in the average level of immediate recalled words was observed in three out of four patients. Effect size indices indicated significant improvement of attention skills in two patients. No treatment effect was observed for semantic and visual memory, or for executive function. An immediate treatment effect was observed in all patients' general cognitive function as assessed with the Alzheimer's Disease Assessment Scale (mean reduction of 5 points), which was maintained and improved further three months post-treatment. The neuropsychological evaluations indicated improved performance three months post-treatment in immediate and delayed recall, attention, phonological verbal fluency, anxiety, and neuropsychiatric symptoms. This study provides preliminary evidence for the efficacy of a novel non-pharmacological treatment using gamma-band TMS in addressing cognitive dysfunction in AD.
