Metamemory following childhood brain injury: A consequence of executive impairment

In this study, we investigated the influence of children’s level of executive functioning on two types of metamemory knowledge following a traumatic brain injury (TBI). For this purpose, 22 children (aged 7 to 14 years) who had sustained a moderate to severe TBI and 44 typically developing children were recruited. The children with TBI were divided into two groups according to the severity of their executive impairment. Injury severity was determined by the Glasgow Coma Scale (GCS) score on admission or by the duration of unconsciousness. All children were then tested on both their knowledge of general memory functioning and their level of memory self-awareness, respectively assessed using the total number of correct responses on an adapted version of a metamemory interview and a self-other discrepancy score on a questionnaire evaluating everyday memory abilities. Data analyses revealed that participants with TBI who suffered impaired executive functions demonstrated less general metamemory knowledge, and underestimated the frequency of their memory problems, compared with children with TBI who had preserved executive functions and with control participants. Considering the well-established effect of metamemory knowledge on people’s spontaneous implementation of strategies, the interest and the importance of these findings on both theoretical and clinical grounds are discussed.     

Gender and health behaviours of hypertensive patients: mediating role of control beliefs

Previous studies have reported gender differences in patients’ health behaviours but few studied hypertensive patients. The potential underlying factors that may mediate gender influences on health behaviours is also a more critical area worthy of investigation. This study examined health locus of control (HLC) as a pathway of gender effects on health behaviours of hypertensive patients. The Multidimensional HLC Scale (Form C) and Wellness behaviour subscale of Health Behaviour Checklist were completed by 400 hypertensive outpatients in two Nigerian hospitals: Enugu State University Teaching Hospital, Park Lane, Enugu, and Bishop Shanahan Specialist Hospital, Nsukka. Hierarchical multiple regression results showed that gender significantly predicted health behaviours. Gender also significantly predicted internal HLC, chance HLC, and other people HLC, but did not predict doctor HLC. The association between gender and health behaviours was fully mediated by internal HLC, chance HLC and other people HLC. Understanding the explanatory mechanisms linking socio-demographic factors and health behaviours is considered of great importance for future research and healthcare intervention.     

Adolescent Friendship as a Dynamic System: Entropy and Deviance in the Etiology and Course of Male Antisocial Behavior

A dynamic systems framework was applied to understand the influence of friendship on antisocial behavior from childhood (age 9-10) through adulthood (age 24-25) for Oregon Youth Study males (N = 206). Boys were videotaped interacting with a friend at ages 14, 16, and 18, and deviant content and interpersonal processes were independently coded. Conditional dyadic interpersonal processes were studied as a communication system and summarized by an index of information entropy (F. Attneave, 1959). High entropy scores represent disorganized, unpredictable patterns of interaction, whereas low entropy scores reflect an organized dialogue. Conversations of early-onset antisocial boys and their best friends were less organized and included more deviant content than those of well-adjusted controls. Prediction analyses, however, revealed an interaction between entropy and deviant talk. Consistent with expectation, males with well-organized interactions (i.e., low entropy) but elevated levels of deviant content were most likely to continue antisocial behavior into adulthood. Findings suggest that individual risk for maladaptation may be amplified by early adolescent friendship dynamics organized around deviance.     

Deviant Peer Affiliation and Problem Behavior: A Test of Genetic and Environmental Influences

This study uses a multitrait, multimethod (MTMM) approach to investigate the genetic and environmental etiologies of childhood deviant peer affiliation (DPA) and problem behavior (PROB). The variability of genetic and environmental estimates by agent and method is also examined. A total of 77 monozygotic and 72 dizygotic twin pairs and each twin's close friend were assessed. The informants included parents, teachers, and twins, and the methods involved questionnaire reports and coder ratings of videotaped dyadic interactions between each twin and their close friend. Twin intraclass correlations and univariate models attributed DPA and PROB to genetic, and shared and nonshared environmental effects. Parameter estimates differed by rater and method, however. Results accentuate the imperative to attend to method effects inherent in MTMM behavioral geneticresearch.

The heterogeneity of picture-supported narratives in Alzheimer's disease

This study describes discourse patterns produced by 46 Alzheimer disease (AD) patients and 53 normal elderly subjects in two picture-supported narratives. Nine measures derived from a cognitive model of discourse processing were obtained and submitted to cluster analysis. Results indicate that discourse patterns elicited from both stimuli were heterogeneous. Further, they fail to clearly differentiate between normal aging and AD in half of the AD patients. Discourse patterns are examined in light of various sources of heterogeneity including severity of cognitive impairment, subject characteristics, and task demands. The usefulness of discourse as a diagnostic and therapeutic tool is discussed.

Community engagement,greening, and violent crime: A test of the greening hypothesis and Busy Streets

Researchers have documented that vacant lot greening can reduce community-level crime and violence. Busy Streets Theory (BST) suggests that residents who are involved in the greening process can help to improve physical environments and build social connections that deter crime and violence. Yet few researchers have explored how community engagement in the greening process may affect crime and violence outcomes. We applied BST to test the effects of community-engaged vacant lot greening compared to vacant lots that received either professional mowing or no treatment, on the density of violent crime around study lots. Using mixed effects regression models, we analyzed trends in violent crime density over the summer months from 2016 to 2018 at 2102 street segments in Youngstown, OH. These street segments fell within 150 meters of an intervention parcel that was classified as one of three conditions: community-engaged maintenance, professional mowing, or no treatment (control). We found that street segments in areas receiving community-engaged maintenance or professional mowing experienced greater declines in violent crime density than street segments in areas receiving no treatment, and more decline occurred in the community-engaged condition compared to the professional mow condition. Our findings support BST and suggest that community-engaged greening of vacant lots in postindustrial cities with a concentrated vacancy can reduce crime and violence.     

Attachment in Adolescence and Borderline Personality Disorder

Borderline personality disorder (BPD) has been conceptualized as a constellation of symptoms related to problems in self-functioning, emotion regulation, and interpersonal relationships. Its etiology has been connected to individuals’ early childhood environment, caregiving relationships, and traumatic life events. Recent literature has noted the potential presence of BPD beginning in adolescence, or even earlier in childhood. Attachment theory offers a lens for understanding the symptoms of borderline personality disorder and identifying potential aspects of treatment that may be specifically valuable for adolescent patients. Adolescence marks a time when the attachment system has increased relevance due to the importance of identity formation, peer relationships, body representations and the development of autonomy at this time, in the face of physical changes and academic challenges. This article will summarize research on attachment, body representations, personality disorders, and features of development in adolescence, in order to enhance clinical understanding of patients who presenting with these types of difficulties.
