Early family context and development of adolescent ruminative style: moderation by temperament

We know very little about the development of rumination, the tendency to passively brood about negative feelings. Because rumination is a risk factor for many forms of psychopathology, especially depression, such knowledge could prove important for preventing negative mental health outcomes in youth. This study examined developmental origins of rumination in a longitudinal sample (N=337; 51% girls) studied in preschool (ages 3? and 4? years) and early adolescence (ages 13 and 15 years). Results indicated that family context and child temperament, assessed during the preschool period, were risk factors for a ruminative style in adolescence. Specifically, early family contexts characterised by over-controlling parenting and a family style of negative-submissive expressivity predicted higher levels of later rumination. These associations were moderated by children's temperamental characteristics of negative affect and effortful control. Further, the interaction of these temperament factors exerted an additional influence on later rumination. Implications for prevention and intervention efforts are discussed.     

Problematic Identity Processes: The Role of Identity Distress

This special issue of Identity: An International Journal of Theory and Research explores some of the anxiety, distress, and difficulties that may be encountered in the identity development process. Despite findings documenting the presence of identity distress in samples from a variety of settings and cultures, it has been slowly moving out of direct attention within the world of clinical psychology and psychiatry. This special issue expands on our understanding of identity distress in a number of ways. It adds to our knowledge of prevalence and severity, as well as its psychological correlates. It examines identity distress under the contexts of traumatic exposure and the refugee experience, and it offers some cross-national comparisons. Also offered is a developmental psychopathology perspective as a way to lay the groundwork for increased prevention and intervention work, and an example of such an intervention program for emerging adults. It is hoped that this special issue on identity distress will shine more light on this important, and possibly growing, yet understudied phenomenon, and will contribute toward expanding and enhancing efforts to foster positive youth development.     

Adult Age Differences in the Access and Deletion Functions of Inhibition

ABSTRACT

This study examined age differences in working memory using a delayed-matching-to-sample (DMTS) task. Based on the inhibitory decline hypothesis, which posits that older adults are more susceptible to interference, age differences were expected to be greater for older adults when irrelevant information was present during encoding. Two experiments tested both the access and deletion functions of inhibition. In both experiments, performance was equated for older and younger participants on a no-interference version of the DMTS task to control for age differences in encoding information into working memory. Results consistently showed equivalent effects of distraction for older and younger adults regardless of the difficulty of the perceptual discrimination of targets and distractors, the degree of processing of the distractors, or the semantic relationship between targets and distractors. These results support theories that propose age differences in encoding to explain age differences in working memory, and are inconsistent with theories that propose that older adults are more susceptible to interference than younger adults.     

The relevance of temporal cues in a fish sound: a first experimental investigation using modified signals in cichlids

Playback experiments have been a useful tool for studying the function of sounds and the relevance of different sound characteristics in signal recognition in many different species of vertebrates. However, successful playback experiments in sound-producing fish remain rare, and few studies have investigated the role of particular sound features in the encoding of information. In this study, we set-up an apparatus in order to test the relevance of acoustic signals in males of the cichlid Metriaclima zebra. We found that territorial males responded more to playbacks by increasing their territorial activity and approaching the loudspeaker during and after playbacks. If sounds are used to indicate the presence of a competitor, we modified two sound characteristics, that is, the pulse period and the number of pulses, in order to investigate whether the observed behavioural response was modulated by the temporal structure of sounds recorded during aggressive interactions. Modified sounds yielded little or no effect on the behavioural response they elicited in territorial males, suggesting a high tolerance for variations in pulse period and number of pulses. The biological function of sounds in M. zebra and the lack of responsiveness to our temporal modifications are discussed.     

Internal state of emergency – working with an international student suffering from trauma in a student counselling service

In this paper I look at the suicidal state of mind of an international student who comes from a country at war and has been traumatized by a violent event. The student is tortured by an internal dilemma surrounding unbearable feelings of guilt and shame that arise when she leaves her home country to study abroad. Her dilemma or survivor guilt triggers an internal contract with herself, whereby she is internally persecuted when she makes an attachment to the university and her course. I suggest that an individual in this state of mind, suffering from post-traumatic stress, has regressed to a primary state of unintegration where the self is at the mercy of psychotic anxieties and the student is at risk of suicide. It is suggested that a safety net made up of the student services and the wider health service can provide a symbolic or mental space and containment for the student's state of mind until she can function as a student.     

Neuropsychologic Deficits in Children with Sickle Cell Disease and Cerebral Infarction: Role of Lesion Site and Volume

Little is known about the correlation between the location and size of cerebral infarction in children and neuropsychologic deficits. We related lesion location and volume on magnetic resonance exams to neuropsychologic performance in 28 children with cerebral infarcts due to sickle cell disease. Seventeen healthy siblings served as a comparison group. Children with anterior cerebral infarcts (n = 7) showed deficits in attention and executive skills, whereas children with more widespread cerebral infarcts (n = 18) showed additional deficits in spatial skills. The volume of cerebral infarction was associated with spatial and language performance, but minimally related to performance in other cognitive domains. The location and volume of cerebral infarction are both important for defining the type and magnitude of cognitive sequelae in childhood stroke.     

Rural Embedded Assistants for Community Health (REACH) Network: First-Person Accounts in a Community–University Partnership

Community research and action projects undertaken by community–university partnerships can lead to contextually appropriate and sustainable community improvements in rural and urban localities. However, effective implementation is challenging and prone to failure when poorly executed. The current paper seeks to inform rural community–university partnership practice through consideration of first-person accounts from five stakeholders in the Rural Embedded Assistants for Community Health (REACH) Network. The REACH Network is a unique community–university partnership aimed at improving rural health services by identifying, implementing, and evaluating innovative health interventions delivered by local caregivers. The first-person accounts provide an insider’s perspective on the nature of collaboration. The unique perspectives identify three critical challenges facing the REACH Network: trust, coordination, and sustainability. Through consideration of the challenges, we identified several strategies for success. We hope readers can learn their own lessons when considering the details of our partnership’s efforts to improve the delivery infrastructure for rural healthcare.
