Aging-related cocontraction effects during ankle strategy balance recovery following tether release in women

Increased antagonistic muscle activation during balance recovery has been documented during proprioceptive reliant responses in older adults. The authors examined ankle muscle cocontraction levels in young and older adults during balance recovery from a tether-release-induced, vestibular-input-reliant perturbation. Nine healthy young adult and 9 older women without history of falls performed maximum isometric plantar flexion and dorsiflexion trials followed by balance recovery trials using the ankle strategy. Surface electromyography data normalized to isometric conditions were analyzed during the 100 ms prior to release, the 50 ms immediately after release, and the 100-ms epochs from 100-400 ms following release. No differences existed in gastrocnemius and soleus activity levels (p > .05), though antagonistic tibialis anterior activity was greater in the older adults during the 300-400 ms epoch (young: 23.5 ± 5.8%, older: 38.7 ± 9.4%; p = .001). Vestibular-dominated perturbations may increase antagonistic activity during the recovery phase in older adults, inhibiting efficient balance recovery during proprioceptive and vestibular reliant perturbations.     

Pride and prejudice: how feelings about the self influence judgments of others

The present research demonstrates that pride has divergent effects on prejudice, exacerbating or attenuating evaluative biases against stigmatized groups, depending on the form of pride experienced. Specifically, three experiments found that hubristic pride--associated with arrogance and self-aggrandizement--promotes prejudice and discrimination, whereas authentic pride--associated with self-confidence and accomplishment--promotes more positive attitudes toward outgroups and stigmatized individuals. Findings generalized to discriminatory judgments (Experiment 2) and were found to be mediated by empathic concern for the evaluative target. Together, these experiments suggest that pride may be a cause of everyday prejudice and discrimination but that these social consequences depend on whether hubristic or authentic pride is experienced, and the degree to which empathic concern is subsequently aroused.     

The control of working memory resources in intentional forgetting: evidence from incidental probe word recognition

We combined an item-method directed forgetting paradigm with a secondary task requiring a response to discriminate the color of probe words presented 1400 ms, 1800 ms or 2600 ms following each study phase memory instruction. The speed to make the color discrimination was used to assess the cognitive demands associated with instantiating Remember (R) and Forget (F) instructions; incidental memory for probe words was used to assess whether instantiating an F instruction also affects items presented in close temporal proximity. Discrimination responses were slower following F than R instructions at the two longest intervals. Critically, at the 1800 ms interval, incidental probe word recognition was worse following F than R instructions, particularly when the study word was successfully forgotten (as opposed to unintentionally remembered). We suggest that intentional forgetting is an active cognitive process associated with establishing control over the contents of working memory.

What’s the Harm? Genetic Counselor Perceptions of Adverse Effects of Genetics Service Provision by Non-Genetics Professionals

Anecdotal accounts suggest some patients have experienced negative outcomes as a result of receiving genetics services from non-genetics providers, but empirical evidence of these incidents and their outcomes is limited. This study examined genetic counselors’ perceptions of the occurrence of such incidents in the state of Minnesota. Twenty-five genetic counselors completed an on-line survey and 20 also participated in a semi-structured telephone interview. The interviewees recalled and described 37 specific incidents they perceived as having negative outcomes for patients and/or their families. Inductive and cross-case analysis revealed common themes including: adverse psychosocial effects, inadequate genetic counseling, genetic testing and screening errors, medical mismanagement, negative shifts in attitudes toward medical providers, and unnecessary use of health care resources. Commonly mentioned strategies for preventing/mitigating negative outcomes included: educational outreach and awareness programs for medical providers and the general public, standardized testing and screening processes, and implementing mechanisms for reporting and addressing adverse events. Additional findings, practice and policy implications, and research recommendations are discussed.     

An examination of attachment,religiousness, spirituality and well-being in a Baptist faith sample

The purpose of this research was to examine a mediational model of attachment, religiousness and spirituality in predicting well-being in people of Christian faith. One hundred and eighty-five participants were recruited from Baptist churches and 19 from a Baptist-based university. Whereas no support was found for a mediational model of attachment, religiousness and spirituality in predicting well-being, support was found for a path model whereby greater levels of insecure attachment to God were associated with lower levels of religious spirituality (RS). In turn, lower levels of RS were associated with greater levels of emotional distress (ED). Therefore, for this sample of Baptists, having a secure attachment to God was related to an increase in religious behaviours, fulfilment with one's prayer life and belief in a purpose for life. It seems that increases in these religious and spiritual variables are related to less ED. This suggests that heightened connection with God, both through religious behaviours and heightened spirituality, is a beneficial pursuit for people of Christian faith.     

When multiple identities compete: The role of centrality in self‐brand connections

The current research provides a framework for understanding how centrality impacts people's choice of brands and related brand connectedness. Motivated by the need to validate their self‐image, individuals use brands to express and confirm their identities. The authors hypothesize that greater centrality of the identity to the self strengthens the connectedness an individual has for brands with value‐expressive properties. Three studies using experimental designs examined whether people whose identity is central to their self‐conception leads to stronger self‐brand connectedness than peripheral identities. In study 1, the results showed that people whose shopping identity was central (versus peripheral) to their self‐concept led to stronger self‐brand connections. Study 2 replicated the findings of study 1 employing brand symbolism as a moderator. Brands high in symbolic properties led to stronger brand connections for an individual's central identities compared with their peripheral identities. Study 3 replicated the influence of centrality on brand choice and self‐brand connections by generalizing this effect to reference group identities. Collectively, the studies provide evidence that individuals integrate brand associations into their self‐concept on the basis of both the centrality of the identity and the level of symbolism the brands holds for an identity.

The CORE‐10: A short measure of psychological distress for routine use in the psychological therapies

Background: There is a need for a generic, short, and easy‐to‐use assessment measure for common presentations of psychological distress in UK primary care mental health settings. This paper sets out the development of the CORE‐10 in response to this need. Method: Items were drawn from the CORE‐OM and 10 items were selected according to a combination of usefulness, coverage of item clusters, and statistical procedures. Three CORE‐OM datasets were employed in the development phase: (1) a primary care sample, (2) a sample from an MRC platform trial of enhanced collaborative care of depression in primary care, and (3) a general population sample derived from the Office of National Statistics Psychiatric Morbidity Follow‐up survey. A fourth dataset comprising a sample from an occupational health setting was used to evaluate the CORE‐10 in its standalone format. Results: The internal reliability (alpha) of the CORE‐10 was .90 and the score for the CORE‐10 correlated with the CORE‐OM at .94 in a clinical sample and .92 in a non‐clinical sample. The clinical cut‐off score for general psychological distress was 11.0 with a reliable change index (90% CI) of 6. For depression, the cut‐off score for the CORE‐10 was 13 and yielded sensitivity and specificity values of .92 (CI=.83–1.0) and 0.72 (CI=.60–.83) respectively. Conclusion: The CORE‐10 is an acceptable and feasible instrument that has good psychometric properties and is practical to use with people presenting with common mental health problems in primary care settings.     

Perceptions Of Benefits and Losses Associated With The Use and Discontinuance Of Anabolic-Androgenic Steroids Among Male Bodybuilders

Abstract

Research has shown the mesomorphic physique to be the most preferred body type among males. Specifically, the hypermesomorphic physique, which displays extreme muscularity and definition, is the most desired (Tucker, 1983). Mishkind, Rodin, Silberstein, and Streigel-Moore (1987) concluded that multiple reasons exist for this preference, most notably the intimate ties that exist among societal conceptions of masculinity, the male sex role, and the mesomorphic physique. Bodybuilding has been perceived as an avenue by which males attempt to develop the preferred mesomorphic physique, and, at times, anabolic-androgenic steroids (AAS) have been ingested as a means for further development. This study entailed in-depth interviews with 10 male bodybuilders, all of whom had taken, or were currently taking, AAS. This article presents the findings of the interviews concerning the perceived benefits of and psychological dependency on AAS. The data, particularly responses concerning psychological dependency, are noted within Mishkind et al.'s framework as a mechanism to avoid loss of muscle strength, muscle mass, and masculinity.     

Regional cortical volume and cognitive functioning following traumatic brain injury

There has been limited examination of the effect of brain pathology on subsequent function. The current study examined the relationships between regional variation in grey matter volume, age and cognitive impairment using a semi-automated image analysis tool. This study included 69 individuals with mild-to-severe TBI, 41 of whom also completed neuropsychological tests of attention, working memory, processing speed, memory and executive functions. A widespread reduction in grey matter volume was associated with increasing age. Regional volumes that were affected also related to the severity of injury, whereby the most severe TBI participants displayed the most significant pathology. Poorer retention of newly learned material was associated with reduced cortical volume in frontal, parietal, and occipital brain regions. In addition, poorer working memory and executive control performance was found for individuals with lower cortical volume in temporal, parietal, and occipital regions. These findings are largely in line with previous literature, which suggests that frontal, temporal, and parietal regions are integral for the encoding of memories into long-term storage, memory retrieval, and working memory. The present study suggests that automated image analysis methods may be used to explore the relationships between regional variation in grey matter volume and cognitive function following TBI.
