Beyond the Caster Semenya Controversy: The Case of the Use of Genetics for Gender Testing in Sport

Caster Semenya won the eight-hundred-meter title in the Berlin World Athletics Championships in 2009. Few hours after, Caster was at the center of a harsh contestation on gender. The International Association of Athletics Federations started an investigation, which was not respectful of her privacy. Caster’s case highlights the need for an improvement in the awareness of genetic counseling principles amongst professionals, the public and various stakeholders. We critically examine the historical steps of gender verification in the Olympics, the violation of genetic counseling principles in Caster’s case and outline some reflections on the complexity of the genetics of Disorders of sex development (DSD). Variability in both genotypes and phenotypes in DSD may not allow any etiological or functional classification at this point in time that could permit uncontroversial gender verification for fairer sport participation. We strongly suggest revisiting the pertinence of gender verification, and the process whereby this is done.     

Intensive Outpatient Comprehensive Behavioral Intervention for Tics: A Clinical Replication Series

Comprehensive Behavioral Intervention for Tics (CBIT) is an efficacious behavioral treatment for Tourette’s disorder. In its standard format, CBIT is completed in 8 sessions over a 10-week period. Unfortunately, significant obstacles (e.g., not having a provider nearby; inability to attend weekly sessions) prevent many individuals from participating in standard outpatient CBIT. An intensive outpatient program that compresses CBIT into a week may help overcome many of these barriers. The present clinical replication series examines treatment outcomes in 5 individuals with Tourette’s disorder. Importantly, 4 out of the 5 participants reported clinically meaningful tic reductions on the Yale Global Tic Severity Scale (YGTSS) at the posttreatment assessment, with an average decrease of 11.5 points across those 4 participants. This represents a 28% decrease in the average posttreatment YGTSS score from the average baseline YGTSS score. Of the 3 participants who completed the 1-month follow-up assessment, 2 participants continued to endorse reductions in their baseline tic severity on the YGTSS and were rated as having a positive response on the Clinician Global Impressions–Improvement subscale. Clinical implications are discussed.     

A 32-society investigation of the influence of perceived economic inequality on social class stereotyping

There is a growing body of work suggesting that social class stereotypes are amplified when people perceive higher levels of economic inequality—that is, the wealthy are perceived as more competent and assertive and the poor as more incompetent and unassertive. The present study tested this prediction in 32 societies and also examines the role of wealth-based categorization in explaining this relationship. We found that people who perceived higher economic inequality were indeed more likely to consider wealth as a meaningful basis for categorization. Unexpectedly, however, higher levels of perceived inequality were associated with perceiving the wealthy as less competent and assertive and the poor as more competent and assertive. Unpacking this further, exploratory analyses showed that the observed tendency to stereotype the wealthy negatively only emerged in societies with lower social mobility and democracy and higher corruption. This points to the importance of understanding how socio-structural features that co-occur with economic inequality may shape perceptions of the wealthy and the poor.     

Exercise Training for Persons with Alzheimer's Disease and Caregivers: A Review of Dyadic Exercise Interventions

Alzheimer's disease (AD) is the most common form of dementia and the prevalence will increase dramatically in the next decades. Although exercise has shown benefits for people with dementia due to AD as well as their caregivers, the impact of a dyadic exercise intervention including both groups as study participants remains to be determined. The authors review the current clinical evidence for dyadic exercise interventions, which are exercise regimens applied to both the person with dementia and the caregiver. A total of 4 controlled trials were reviewed. This review shows that dyadic exercise interventions are feasible and may produce a positive effect on functional independence and caregiver burden. However, there was insufficient evidence to support a benefit of dyadic exercise intervention on cognitive performance and on behavioral and neuropsychiatric symptoms in participants with dementia due to AD. A dyadic exercise intervention improves functional independence and caregiver burden. However, there is a need for well-designed randomized controlled clinical trials to confirm these benefits and to investigate several important points such as the effects of a dyadic exercise intervention on cognitive and noncognitive outcomes of AD, the optimal intensity of exercise training, and the cost effectiveness of such a program.     

Translating sales effort into service performance: it's an emotional ride

It has been broadly assumed by both researchers and managers that the more effort salespeople exert, the better their performance outcomes are likely to be. However, organizations are placing an increasing emphasis not just on objective sales outcomes, but on subjective, customer service outcomes as well. This research tests relationships between employee effort and relational performance. We develop and test the position that employee effort reaches a point of diminishing returns, after which relational performance decreases. Further, in an effort to bound our model, we test the moderating role played by employees' emotional intelligence in this relationship. We test our study model in a lagged, multisource field study, matching survey data collected from 107 employees and 19 supervisors, relational performance metrics, and archived effort data collected for a period of 3 months pre–survey data collection. The results from our analysis indicate that the relationship between effort and relational performance is captured by an inverted U-shaped function that is significantly moderated by emotional intelligence. We find that the effort of employees with low EI reaches an identifiable point of diminishing returns; however, the more effort those with high EI exert, the better their relational performance outcomes tend to be.     

Salesperson ambidexterity and customer satisfaction: examining the role of customer demandingness,adaptive selling,and role conflict

This research investigates the effects of sales-service ambidexterity on salesperson role perceptions, behaviors, and customer satisfaction. Using a business-to-business, salesperson-customer sample, we build and test a model which highlights both the positive and negative consequences of this simultaneous goal pursuit. Specifically, while sales-service ambidexterity positively impacts adaptive selling behaviors, it also increases perceptions of role conflict among salespeople. Customer demandingness moderates these relationships. Taken together, the results provide insights for firms on how to manage their sales force to optimize both sales and service outcomes based on characteristics of their salespeople and customers.     

Perception of alternated speech operates similarly in young and older adults with age-normal hearing

When speech is rapidly alternated between the two ears, intelligibility declines as the rate of alternation approaches 3 to 5 switching cycles per second, and then, paradoxically, returns to a good level beyond that point. We tested intelligibility when shadowing was used as a response measure (Experiment 1), when recall was used as a response measure (Experiment 2), and when time-compression was used to vary the speech rate of the presented materials (Experiment 3). In spite of claims that older adults are generally slower in switching attention, younger and older adults did not differ in the critical alternation rates producing minimal intelligibility. We suggest that the point of minimal intelligibility in alternated speech reflects an interaction between (1) the rate of disruption induced by breaking the speech stream between two sound sources, (2) the amount of contextual information per ear, and (3) the size of the silent gaps separating the speech elements that must be perceptually bridged.     

Neurocognitive Functioning in AD/HD,Predominantly Inattentive and Combined Subtypes

The Predominantly Inattentive (PI) and Combined (CB) subtypes of AD/HD differ in cognitive tempo, age of onset, gender ratio, and comorbidity, yet a differentiating endophenotype has not been identified. The aim of this study was to test rigorously diagnosed PI, CB, and typical children on measures selected for their potential to reveal hypothesized differences between the subtypes in specific neurocognitive systems (anterior vs. posterior attentional systems) and processes (arousal vs. activation). Thirty-four CB and 26 PI children meeting full DSM-IV criteria for subtype both in school and at home, without confounding reading disability or emotional disorder, were enrolled along with 20 typically developing children. Neurocognitive functions measured included attention, inhibitory control, working memory, learning, and executive functions. Tasks included the Stroop, Wisconsin Card Sorting Test, Continuous Performance Test (CPT). Buschke Selective Reminding Test, ad the Tower of London (TOL), as well as instruments developed by Posner and Sternberg, and tasks assessing the impact on reaction time of [corrected] varying preparatory intervals and stimulus/response complexity. After co-varying for IQ, subtypes differed primarily on measures of impulsivity during tests of vigilance (CPT) and executive function (TOL), with the CB group showing greater impulsivity than both other groups. In addition, the PI group showed worse performance than CB and control groups on the WISC-III Processing Speed Index. Whether analyzed with or without an IQ co-variate, there was no support in the data for hypothesized differences between subtypes in functioning of the anterior vs. posterior attentional systems, nor in involvement of arousal vs. activation processes. The results indicate that the PI and CB subtypes are best differentiated by ratings, observations and tests of cognitive tempo and behavioral impulsivity. Neuropsychological methods have yet to identify critical neuropsychological [corrected] substrates of these differences.     

Counting black sheep: Contextualizing therapeutic relations

In this paper we draw on feminist and post-colonial theory to situate an account of a six-month therapy between a black, Asian woman therapist and a woman patient of mixed parentage, within contemporary Britain. We draw on this analysis to further the debates between psychotherapeutics and social theory, challenging each in three ways. First, in relation to the literature on culture, class, gender and sexuality in psychotherapy, we indicate how these enter into the therapeutic relation in distinct and intersecting ways, which, second, challenge the separation between inner and outer worlds frequently maintained within psychotherapy circles. Third, in terms of the correlative challenge psychotherapeutic perspectives pose for social theorists and activists, we highlight how the therapist's constructive and explicit use of her power and socio-cultural position was central to the progress of this client's therapy. Finally, we reflect on the broader questions around the theorizing of culture and gender within psychotherapy, including the available positions and representations of black therapists as well as black patients.     

Semantic clustering as a neuropsychological predictor for amnestic-MCI

ABSTRACT

Recent research has demonstrated that patients with Alzheimer's disease (AD) show deficits in semantic processing when compared to cognitively healthy individuals. This difference is thought to be attributed to losses in higher cortical systems that are predominantly associated with executive functioning. The first aim of the study will be to determine if differences in semantic clustering can accurately differentiate patients with amnestic mild cognitive impairment (aMCI) from cognitively normal (CN) individuals. The second aim will be to determine the extent to which semantic processing might be associated with executive functions. Data from 202 (134 CN, 68 aMCI) participants were analyzed to quantify differences in semantic clustering ratios on the HVLT-R. Study participants ages ranged from 51 to 87 with education ranging from 6 to 20 years. ANCOVA revealed statistically significant differences on semantic clustering ratios (p < .001). Moderate correlations between semantic clustering Category Fluency Test (r = .45) were also found. Statistically significant group differences were also present on Trails-B and WAIS-R Digit Symbol performance (p < .001). Overall, these data indicate that deficits in semantic clustering are present in aMCI patients.
