A developmental deficit in short-term phonological memory: Implications for language and reading

Abstract

QU, an eight-year-old boy, was identified from a large scale normative study on the basis of his greatly reduced digit span, combined with normal long-term memory and non-verbal intelligence. Further investigation indicated that his visual STM was normal, but that he was clearly impaired on two verbal STM tests, nonword repetition, and memory span for words. His span showed clear effects of phonological similarity and word-length, suggesting qualitatively normal functioning of the phonological loop component of working memory, despite a quantitative impairment in level of performance. This pattern resembles that found in an earlier study of children with a specific language disorder. We tested QU on measures of vocabulary, syntax, and reading, and found him to be substantially below the age norms on all three. The implications of these findings are discussed for the role of the phonological loop in language development.     

Couples and Diabetes: A 30-Year Narrative Review of Dyadic Relational Research

Diabetes is a chronic condition that affects both members of a couple. However, relatively few studies have focused on the entire couple system as the unit of observation when examining the psychosocial impact of this disease. This narrative review examines the literature between 1980 and 2010 that uses the couple as the unit of observation. A total of 49 articles were identified for review. Articles were grouped by their central themes or outcomes: (1) sexual functioning, (2) relationship adjustment and support, (3) culture and spirituality, (4) treatment/education programs, and (5) diabetes as a risk factor. Research and clinical implications such as increasing the utilization of dyadic analytical strategies and the importance of assessing illness burden from each partners’ perspective are discussed. Identified benefits of incorporating the couple dyad for future research and clinical practice included: (1) understanding the influence of variables such as a non-diabetic partner and gender have on diabetes adjustment and management, (2) the role disease severity and management of diabetes by the partner living with diabetes has on spousal support and non-diabetic partner emotional wellbeing, (3) the interdependent nature of couple outcomes in the areas of adjustment to sexual dysfunction, perceived illness burden, and couple satisfaction, as well as, (4) disease as both an individual and a shared experience among couples.     

Gazzaniga,Michael S., Who's in Charge? Free Will and the Science of the Brain

A review, with reflections, of Michael S. Gazzaniga's (2011) book, Who's in Charge? Free Will and the Science of the Brain. Gazzaniga, a distinguished neuroscientist, wishes to connect contemporary understandings of the functioning of the human brain to the proper functioning of the American courtroom. What effect, if any, should these current understandings (and current technologies) have on legal conceptions of personal responsibility, guilt, and punishment? If, as many neuroscientists hold, the functioning of the brain wholly determines the functioning of the mind, can people rightly be held responsible for their actions? Gazzaniga argues that they can.     

Children's responses to entry failure: attention deployment patterns and self-regulation skills

In this study the authors investigated associations among children's observed responses to failure in an analogue entry situation, their attention deployment patterns, and skills and processes associated with self-regulation. Participants were 54 kindergarten and first-grade students who were either aggressive-rejected or low aggressive-popular based on peer nominations. Inhibitory control predicted the tendency to respond to entry failure by stopping and watching the group's activity. Baseline vagal tone and other-directed attention predicted children's tendency to change entry strategies after failure. Parent-rated attention skills moderated the relation between children's attention deployment patterns during the entry task and their responses to entry failure. Children who engaged in more other-directed attention were less likely to turn to solitary play after entry failure but only if they had high or moderate levels of attentional control. Other-directed attention was related to repeating previous entry bids without modification after entry failure but only when children had high levels of attention problems.     

Repeating,Not Simply Recollecting, <Emphasis Type="Italic">Repetition</Emphasis>: On Kierkegaard’s Ethical Exercises

This essay argues for a formative, and not simply abstract, aspect to the philosophy of religion by attending to the practices of writing employed in Søren Kierkegaard’s pseudonymous work Repetition. By locating this text within an ethical tradition that focuses upon the practices that form subjects, rather than simply the formulation of a theory, its seemingly literary performances can be viewed as exercises. In particular, this text deploys and transforms the Stoic practices of self writing, in the form of keeping notebooks and letter writing, so as to cultivate capabilities. This indirect ethical instruction does not, however, lead to the formation of autonomous ethical subjects, but to the cultivation of capabilities that are only possible in the relational space of vulnerability, service and dependence.     

Connecting Youth Violence Prevention, Positive Youth Development, and Community Mobilization

Several disconnects serve to weaken the use of evidence based programming in community settings. Communities face the need to address the challenges of multiple risk behaviors faced by adolescents in their communities, but must also work to support successful transitions to adulthood and the broader positive development of their youth. The stronger integration of positive youth development and prevention of youth risk at the community level may offer an opportunity to support the implementation and ongoing development of evidence-based practices (EBPs). This article provides an overview of the VCU Clark-Hill Institute for Positive Youth Development Institute's community mobilization effort in Richmond, Virginia and reports preliminary findings from our integrated mobilization efforts. First, we review the role of our Community Advisory Council in their collaborative work to support positive youth development and reduce risk for youth violence. Next, we present examples of institute efforts in providing technical assistance relevant to supporting the use and development of EBPs. We then discuss the adaptation of an evidence-based program to target positive youth development. We also present overviews from qualitative investigations examining barriers and supports that inform and are relevant to the implementation of EBPs. Finally, we consider ways in which community efforts inform and shape institute efforts to develop EPBs. Taken together, these activities provide examples of how community-based mobilization efforts can integrate and inform the implementation of EBPs and the role and use of prevention science as a tool in supporting effective programming to promote positive youth development and prevent youth violence.     

Semantic dementia and persisting Wernicke's aphasia: linguistic and anatomical profiles

Few studies have directly compared the clinical and anatomical characteristics of patients with progressive aphasia to those of patients with aphasia caused by stroke. In the current study we examined fluent forms of aphasia in these two groups, specifically semantic dementia (SD) and persisting Wernicke’s aphasia (WA) due to stroke. We compared 10 patients with SD to 10 age- and education-matched patients with WA in three language domains: language comprehension (single words and sentences), spontaneous speech and visual semantics. Neuroanatomical involvement was analyzed using disease-specific image analysis techniques: voxel-based morphometry (VBM) for patients with SD and overlays of lesion digitized lesion reconstructions in patients with WA. Patients with SD and WA were both impaired on tasks that involved visual semantics, but patients with SD were less impaired in spontaneous speech and sentence comprehension. The anatomical findings showed that different regions were most affected in the two disorders: the left anterior temporal lobe in SD and the left posterior middle temporal gyrus in chronic WA. This study highlights that the two syndromes classically associated with language comprehension deficits in aphasia due to stroke and neurodegenerative disease are clinically distinct, most likely due to distinct distributions of damage in the temporal lobe.     

Intrasexual peer aggression and dating behavior during adolescence: an evolutionary perspective

It has been suggested that the use of intrasexual aggression is a form of competition associated with reproductive opportunities. Here the authors investigated the relationship between retrospective dating and flirting behavior and peer aggression and victimization during middle and high school. Results indicate that the use of peer aggression was associated with adaptive dating outcomes in both sexes, whereas experiencing peer victimization was correlated with maladaptive dating behaviors among females only. Females who perpetrated high levels of indirect (i.e. nonphysical) aggression reported that they began dating at earlier ages in comparison to their peers, whereas aggressive males reported having more total dating partners. Experiencing female-female peer victimization was correlated with a later onset of dating behavior, more total dating partners, and less male flirtation while growing up. This report strengthens the connection between adolescent peer aggression and reproductive competition, suggesting a potential functionality to adolescent peer aggression in enhancing one's own mating opportunities at the expense of rivals.     

Using a Family History Intervention to Improve Cancer Risk Perception in a Black Community

Few studies examine the use of family history to influence risk perceptions in the African American population. This study examined the influence of a family health history (FHH) intervention on risk perceptions for breast (BRCA), colon (CRC), and prostate cancers (PRCA) among African Americans in Pittsburgh, PA. Participants (n = 665) completed pre- and post-surveys and FHHs. We compared their objective and perceived risks, classified as average, moderate, or high, and examined the accuracy of risk perceptions before and after the FHH intervention. The majority of participants had accurate risk perceptions post-FHH. Of those participants who were inaccurate pre-FHH, 43.3%, 43.8%, and 34.5% for BRCA, CRC, and PRCA, respectively, adopted accurate risk perceptions post-FHH intervention. The intervention was successful in a community setting. It has the potential to lead to healthy behavior modifications because participants adopted accurate risk perceptions. We identified a substantial number of at-risk individuals who could benefit from targeted prevention strategies, thus decreasing racial/ethnic cancer disparities.
