Post‐Traumatic Symptoms Among Victims of Workplace Bullying: Exploring Gender Differences and Shattered Assumptions

The aims of the present study were twofold: assessing the prevalence and intensity of post‐traumatic stress disorder (PTSD) symptoms in victims of bullying, and exploring whether victims of bullying differ in their basic assumptions compared to a control group. A total of 183 victims of bullying and 183 control group participants took part in the research. The results showed that 42.6% of the total sample met all DSM‐IV‐TR criteria for PTSD, whereas 54.1% did not fulfill the A1 criterion. Post‐traumatic symptoms were more prevalent among women (49%), as compared to men (35.3%). Furthermore, victims showed significantly more negative beliefs about the world, the people, and themselves, compared to their non‐bullied controls. These results fit well with cognitive theory of trauma.     

A Dilemma for Higher-Order Theories of Consciousness

Higher Order theories of consciousness have their fair share of sympathisers, but the arguments mustered in their support are—to my mind—unduly persuasive. My aim in this paper is to show that Higher Order theories cannot accommodate the possibility of misrepresentation without either falling into contradiction, or collapsing into a First-Order theory. If this diagnosis is on the right track, then Higher Order theories—at least in the specific versions here considered—fail to give an account of what they set out to explain: what is distinctive of ‘conscious’ phenomena.     

Improvement in working memory is not related to increased intelligence scores

The acknowledged high relationship between working memory and intelligence suggests common underlying cognitive mechanisms and, perhaps, shared biological substrates. If this is the case, improvement in working memory by repeated exposure to challenging span tasks might be reflected in increased intelligence scores. Here we report a study in which 288 university undergraduates completed the odd numbered items of four intelligence tests on time 1 and the even numbered items of the same tests one month later (time 2). In between, 173 participants completed three sessions, separated by exactly one week, comprising verbal, numerical, and spatial short-term memory (STM) and working memory (WMC) tasks imposing high processing demands (STM–WMC group). 115 participants also completed three sessions, separated by exactly one week, but comprising verbal, numerical, and spatial simple speed tasks (processing speed, PS, and attention, ATT) with very low processing demands (PS-ATT group). The main finding reveals increased scores from the pre-test to the post-test intelligence session (more than half a standard deviation on average). However, there was no differential improvement on intelligence between the STM-WMC and PS-ATT groups.     

Blockade of nucleus basalis magnocellularis or activation of insular cortex histamine receptors disrupts formation but not retrieval of aversive taste memory

Recent research, using several experimental models, demonstrated that the histaminergic system is clearly involved in memory formation. This evidence suggested that during different associative learning tasks, histamine receptor subtypes have opposite functions, related to the regulation of cortical cholinergic activity. Given that cortical cholinergic activity and nucleus basalis magnocellularis (NBM) integrity are needed during taste memory formation, the aim of this study was to determine the role of histamine receptors during conditioned taste aversion (CTA). We evaluated the effects of bilateral infusions of 0.5 μl of pyrilamine (100 mM), an H₁ receptor antagonist, into the NBM, or of R-α-methylhistamine (RAMH) (10 mM), an H₃ receptor agonist, into the insular cortex of male Sprague-Dawley rats 20 min before acquisition and/or retrieval of conditioned taste aversion. The results showed that blockade of H₁ receptors in NBM or activation of H₃ receptors in the insular cortex impairs formation but not retrieval of aversive taste memory. These results demonstrated differential roles for histamine receptors in two important areas for taste memory formation and suggest that these effects could be related with the cortical cholinergic activity modulation during CTA acquisition.     

Belief in a just world and well-being of bullies,victims and defenders: a study with Portuguese and Indian students

Abstract

Previous findings characterize the belief in a just world (BJW) as a valuable resource for maintaining positive well-being and assimilating injustice. The present cross-sectional study applies just world research to school bullying and tested the hypotheses that the personal BJW is positively correlated with subjective well-being, here particularly school distress. In this paper the generalizability of this association is tested in victims, bullies, and defenders, and across gender and also two countries with different cultures, Portugal and India. We will test if BJW can best be interpreted as a personal resource (main effect) or a buffer (moderator) for the distress of victims, bullies and defenders of the victims. The participants were 465 school students (Portuguese sample: 187 students aged between 12 and 18 years; Indian sample: 278 Indian students aged between 14 and 17 years). Overall, the results of the study supported the personal resource hypothesis. The stronger the adolescents’ endorsements of the BJW the less they felt distressed at school, and this was true independent of their bullying behavior and within both sexes and across both samples, although boys, bullies, and Portuguese adolescents experienced more distress and defenders experienced less distress at school.     

Psychosocial Adjustment in Male-to-Female Transsexuals: An Overview of the Research Evidence

Transsexualism has been defined as an extreme gender dysphoria; it refers to unhappiness with one's biological sex and the desire to have the body of the opposite sex and to be regarded by others as a member of that other sex. Transsexualism is not a common condition, but its prevalence is not yet known. A large number of transsexuals receive hormonal treatment and sex reassignment surgery (SRS). In spite of years of poor quality research, due in part to methodological problems, recent research on surgical outcomes has provided important information. However, psychological research into transsexualism has ignored the cognitive style and psychological functioning of transsexuals, and very little effort has been made to incorporate research findings into the development of psychological treatments to improve the quality of life for transsexuals.
