Long-term adverse health outcomes of physical workplace violence: a 7-year population-based follow-up study

The aim of the present study was to analyse whether physical workplace violence increases the risk of long-term adverse health outcomes (i.e., high number of visits to the general practitioner, outpatient treatment, hospital admittance, antidepressant use, and/or having a mental disorder). The study was based on representative survey data from 2006 and 2010 (entitled “How are you?”) merged with register data for a 7-year follow-up period (N = 30,812). To examine if physical workplace violence was a predictor of adverse health outcomes, logistic regression models were conducted for the total follow-up period and for each follow-up year with the different outcome measures as the dependent variables. In the follow-up period, individuals who were exposed to physical workplace violence had a higher number of visits to the general practitioner, had more often received outpatient treatment, and had more often been admitted to hospital than their non-exposed counterparts. Moreover, exposed individuals had higher odds of using antidepressants in the last three follow-up years than did non-exposed individuals. The findings call for heightened attention to securing preventive as well as rehabilitative strategies to help victims of physical workplace violence with the aim of avoiding adverse long-term health consequences.     

Developmental differences in the neural correlates supporting semantics and syntax during sentence processing

School‐aged and adolescent children continue to demonstrate improvements in how they integrate and comprehend real‐time, auditory language over this developmental time period, which can have important implications for academic and social success. To better understand developmental changes in the neural processes engaged during language comprehension in this age group, we use electroencephalography to investigate how 8–9 year old, 12–13 year olds, and adults process semantics and syntax in naturally paced, auditory sentences. Participants listened to semantically and syntactically correct and incorrect sentences and were asked to complete an acceptability judgment task. When processing a semantic error, developmental differences were observed in theta, but not the N400, suggesting that the N400 may be too gross a measure to identify more subtle aspects of semantic development that occur in the school years. For the syntactic task, errors resulted in a larger P600 and greater beta decrease than correct sentences, but the amplitude and location of the P600 and amplitude of beta decreases differed as a function of age, suggesting specialization of syntactic skills is ongoing through adolescence. The current findings shed new light on the development of the neural oscillations supporting language comprehension and suggest that the neural substrates underlying semantic processing reach adult‐like levels at a younger age than those underlying syntactic processing.     

Performance Involvement,Identity, and Emotion Among Cisgender Male Drag Queens

Quantitative research on levels of depression and gender dysphoria in drag populations is lacking. It is possible that this lack occurs because researchers tend to include drag queens within transgender samples. Such sampling practices may result in inaccurate assumptions about drag queen populations. This study established rates of depression and gender dysphoria in a sample of self-identified cisgender drag queens. Participants reported low levels of gender dysphoria and significantly lower levels of depression than have been found among trans women, however, these participants presented with higher rates of depression than have been found among gay men who do not perform drag. Higher rates of involvement in drag performance were positively correlated with depression and negatively correlated with gender dysphoria. Results indicate that self-identified cisgender drag queens are unlikely to experience gender dysphoria and are less depressed than samples of trans women. The researchers discuss implications and future directions for mental health practitioners.     

The Influence of Culture on Consumer Impulsive Buying Behavior

Impulse buying generates over $4 billion in annual sales volume in the United States. With the growth of e‐commerce and television shopping channels, consumers have easy access to impulse purchasing opportunities, but little is known about this sudden, compelling, hedonically complex purchasing behavior in non‐Western cultures. Yet cultural factors moderate many aspects of consumer's impulsive buying behavior, including self‐identity, normative influences, the suppression of emotion, and the postponement of instant gratification. From a multi‐country survey of consumers in Australia, United States, Hong Kong, Singapore, and Malaysia, our analyses show that both regional level factors (individualism–collectivism) and individual cultural difference factors (independent –interdependent self‐concept) systematically influence impulsive purchasing behavior.     

Declines in switching underlie verbal fluency changes after unilateral pallidal surgery in Parkinson's disease

Declines in verbal fluency are consistently reported in patients with Parkinson's disease (PD) after pallidal surgery. In the present study, the clustering and switching components of semantic or category fluency (oral naming of items obtainable in supermarkets) were examined at baseline and four months after unilateral deep brain stimulation or pallidotomy in 45 patients with PD (30 left, 15 right pallidal surgery). Post-operative declines were observed for supermarket fluency total score and switching, but not for average cluster size. These findings support the proposal that semantic fluency decrements after pallidal surgery reflect a disruption of frontal-basal ganglia circuits mediating efficient shifting between semantic categories, or perhaps efficient access to categories, rather than a degradation of semantic stores.     

Stigma and Ostracism Associated with HIV/AIDS: Children Carrying the Secret of Their Mothers' HIV+ Serostatus

Qualitative interviews were conducted with mothers (N = 47) who had disclosed their HIV status to their children. The majority of mothers explicitly told their child not to disclose to other people that she was HIV-positive because they feared repercussions in the way of stigma and ostracism for both themselves and their child. Approximately one-fourth of the mothers identified safe people, to whom their child could discuss her serostatus, such as family members, health care providers, or therapists. The majority of the children respected their mothers' wishes; only four children disclosed to someone after being explicitly told not to do so. A significant number of children expressed concerns about their friends finding out, fearing that they would be ostracized or that it would be assumed they were also infected. In addition, the children did not want others to find out because they wanted to protect their mothers. The burden of keeping the secret of their mothers' serostatus does seem to be a stressor for some of the children.     

Human central auditory plasticity associated with tone sequence learning

We investigated learning-related changes in amplitude, scalp topography, and source localization of the mismatch negativity (MMN), a neurophysiological response correlated with auditory discrimination ability. Participants (n = 32) underwent two EEG recordings while they watched silent films and ignored auditory stimuli. Stimuli were a standard (probability = 85%) and two deviant (probability = 7.5% each for high [HD] and low [LD]) eight-tone sequences that differed in the frequency of one tone. Between recordings, subjects practiced discriminating the HD or LD from the standard for 6 min. The amplitude of the LD MMN increased significantly across recordings in both groups, whereas the amplitude of the HD MMN did not. The LD was easier to discriminate than was the HD. Thus, practicing either discrimination increased the MMN for the easier discrimination. Learning and changes in the LD MMN amplitude were highly correlated. Source localizations of event-related potentials (ERPs) to all stimuli revealed bilateral sources in superior temporal regions. Compared with the standard ERP, the LD ERP revealed a stronger source in the left superior temporal region in both recordings, whereas the right-sided source became stronger after learning. Consistent with prior studies of auditory plasticity in animals and humans, tone sequence learning induced rapid neurophysiological plasticity in the human central auditory system. The results also suggest that there is asymmetric hemispheric involvement in tone sequence discrimination learning and that discrimination difficulty influences the time course of learning-related neurophysiological changes.
