Precursors to aggression are evident by 6 months of age

We tested the hypothesis that developmental precursors to aggression are apparent in infancy. Up to three informants rated 301 firstborn infants for early signs of anger, hitting and biting; 279 (93%) were assessed again as toddlers. Informants' ratings were validated by direct observation at both ages. The precursor behaviours were significantly associated with known risk factors for high levels of aggressiveness. Individual differences were stable from early infancy to the third year and predicted broader conduct problems. These findings suggest that some individuals set forth on the trajectory to high levels of aggression by 6 months of age. The findings have implications for developmental studies of aggression, clinical prevention and intervention strategies, and theoretical considerations regarding the detection of precursors in different domains of development.     

Bereaved Parents' Perspectives on Informal Social Support: “What Worked for You?”

This study identified and explored the informal social supports that bereaved parents found helpful following the death of their primary school-aged child. Ten participants were interviewed using a semistructured interview schedule. Data were transcribed and analyzed using content and thematic analysis. Results indicate the existence of novel informal supports that enrich contemporary literature. Nine common characteristics of helpful support emerged from the analysis; the specifics of each depended on congruence with parents' unique framework of meaning. Parents also identified five ways to strengthen informal social support. Implications for health promotion research and practice in parental bereavement are discussed.     

Emerging Adults’ Behavior Problems and Coping Following Hurricanes

When experiencing natural disasters, coping is important. Individuals who have behavior problems may use less effective coping, however. This study sought to better understand the relationship between emerging adults’ behavior problems and coping following hurricanes. Using a sample of 193 emerging adults, correlations suggested that emerging adults who reported more behavior problems also endorsed higher levels of avoidant coping. More specifically, multivariate analyses of variance and subsequent post hoc analyses indicated that emerging adults who were experiencing relatively low levels of both internalizing and externalizing behavior problems endorsed avoidant coping significantly less often relative to those emerging adults who were experiencing relatively high levels of internalizing behavior problems only and those who were experiencing relatively high levels of both types of behavior problems. These results suggested that those who experience behavior problems following hurricanes may benefit from interventions that could improve the coping that they utilize.     

Innovations in the Identification and Referral of Mothers at Risk for Depression: Development of a Peer-to-Peer Model

This paper describes a feasibility study of a peer-delivered prevention intervention to identify mothers at high risk for depression and facilitate engagement in mental health services for their emotional health. Sixteen family peer advocates and their supervisors partnered with academic researchers over a period of 6 months to develop a four-session intervention that focused on identifying symptoms of depression, providing education about depression and treatment, actively linking caregivers to treatment for their own emotional health, and assisting caregivers in becoming active participants in their mental health care. Collaborating with peers to develop the model enhanced its perceived relevance and utility, and resulted in an intervention that was complimentary to their roles and the mission of peer-delivered support services. Peer/professional partnerships may be beneficial for enhancing the feasibility and acceptability of research efforts; the impact of peers’ participation in the current project and the need for future research to develop and study peer-delivered models is discussed.     

Alignment to visual speech information

Speech alignment is the tendency for interlocutors to unconsciously imitate one another’s speaking style. Alignment also occurs when a talker is asked to shadow recorded words (e.g., Shockley, Sabadini, & Fowler, 2004). In two experiments, we examined whether alignment could be induced with visual (lipread) speech and with auditory speech. In Experiment 1, we asked subjects to lipread and shadow out loud a model silently uttering words. The results indicate that shadowed utterances sounded more similar to the model’s utterances than did subjects’ nonshadowed read utterances. This suggests that speech alignment can be based on visual speech. In Experiment 2, we tested whether raters could perceive alignment across modalities. Raters were asked to judge the relative similarity between a model’s visual (silent video) utterance and subjects’ audio utterances. The subjects’ shadowed utterances were again judged as more similar to the model’s than were read utterances, suggesting that raters are sensitive to cross-modal similarity between aligned words.     

Age-Related Changes and the Attention Network Task: An Examination of Alerting,Orienting, and Executive Function

ABSTRACT

The effects of aging on alerting, orienting, and executive function were examined with the use of the Attention Network Task, which combines the Posner spatial cuing task and the Eriksen flanker task into a single procedure. We found that older adults showed significantly less alerting than young adults in response to a warning cue, although there were no age differences in orienting or executive function once processing speed was taken into account. We suggest that age differences in alerting may depend in part upon the presentation duration or persistence of the warning cue.     

Recollection Training and Transfer Effects in Older Adults: Successful Use of a Repetition-Lag Procedure

Abstract

We examined an approach aimed at training consciously-controlled recollection, introduced by Jennings and Jacoby (2003) Jennings, J. M. and Jacoby, L. L. 2003. Improving memory in older adults: Training recollection. Neuropsychological Rehabilitation, 13: 417–440. [CSA][CROSSREF][Taylor & Francis Online], [Web of Science ®] , [Google Scholar], for its ability to replicate and generalize. A continuous recognition task, requiring recollection to identify the occurrence of repeated items over gradually increasing lag intervals (number of intervening items between the first and second presentation of a repeated word), was given to a group of older adults twice a week for three weeks. Pre-and-post training performance was assessed on multiple measures and compared with a recognition practice and no contact control group. Recollection training proved successful; accurate identification of repeated items increased across a lag interval of 2 to 18 intervening items. Post-training gains following recollection training were found on n-back, self-ordered pointing, source discrimination and digit symbol substitution, but not with reading span or the CVLT-II. No changes were identified in the other groups. Gains from recollection training seem to transfer successfully in older adults.     

The Lived Experiences of Sex Workers in South Africa: An Existential Phenomenological Exploration

We explored the lived experiences of sex workers in South Africa by employing a phenomenological methodology. Five women between the ages of 34 and 48 years who were/are involved in this industry were interviewed between January and March 2008. Through the use of thematic analysis four common themes in their experiences were identified and are elucidated in this article. These themes are: (a) pervasive experiences of abuse and neglect during childhood, (b) entry into sex work, (c) life as a sex worker and (d) trauma and resilience. The lived experiences of the participants were integrated with the literature in order to create a contextualised picture and a deeper understanding of the experience of a sex worker, as well as to assist informing the debate on sex work in South Africa.     

The Limitations of “Vulnerability” as a Protection for Human Research Participants

Vulnerability is one of the least examined concepts in research ethics. Vulnerability was linked in the Belmont Report to questions of justice in the selection of subjects. Regulations and policy documents regarding the ethical conduct of research have focused on vulnerability in terms of limitations of the capacity to provide informed consent. Other interpretations of vulnerability have emphasized unequal power relationships between politically and economically disadvantaged groups and investigators or sponsors. So many groups are now considered to be vulnerable in the context of research, particularly international research, that the concept has lost force. In addition, classifying groups as vulnerable not only stereotypes them, but also may not reliably protect many individuals from harm. Certain individuals require ongoing protections of the kind already established in law and regulation, but attention must also be focused on characteristics of the research protocol and environment that present ethical challenges.
