The impact of perceived effort–reward imbalance on workplace bullying: also a matter of organizational identification

Work environments characterized by inadequate work conditions have been widely recognized as being particularly prone to the occurrence and exacerbation of bullying behavior. Accordingly, this longitudinal study aimed to explore whether the impact of effort–reward imbalance (ERI) on workplace bullying was mediated by a lower perception of organizational justice, and whether the association between ERI and perceptions of justice was moderated by organizational identification. In the current study, a sample of N = 195 Spanish employees from different occupational sectors filled in an online questionnaire at two different times with a time lag of 8 months. In line with the hypothesized moderated mediation model, results showed that organizational justice mediated the impact of ERI on workplace bullying. Moreover, the effect of perceived ERI on organizational justice was stronger for employees with low organizational identification. Overall, this study can contribute to better understanding how and when ERI boosts the risk of workplace bullying. Accordingly, early intervention designed to buffer the negative effects of ERI should focus on increasing individual levels of organizational identification.     

Use of the ten-point clock test to compare executive functioning across 24 months in patients with subcortical vascular dementia

The Ten-point Clock Test can be used to identify early forms of Alzheimer's disease because it is reliable, well accepted, and easily administered at the bedside. Nevertheless, its clinical role in the detection of early dementia and its correlations with other cognitive processes is still under investigation. Vascular dementia is an uncertain nosological entity, in which unevenly distributed patterns of cognitive deficits comprising slowing of cognitive processing and impairment of executive function occur. The present study assessed how the Clock Test scores correlated with a number of other neuropsychological and functional tests in a sample of 144 patients with vascular dementia, who were followed for a period of 24 mo. At baseline, at 12 mo. and at 24 mo. subjects were administered a battery of tests, including the Mini-Mental State Examination, word fluency, visuospatial skills, an evaluation of hetero- and autotopognosia (knowledge of self), the Proverbs Test, and the Ten-point Clock Test. For these patients scores on the Clock Test correlated significantly with semantic abilities, with abstract reasoning capacities, visuospatial perception, and with right and left recognition.     

Analyzing aphasia data in a multidimensional symptom space

The utility of single-case vs. group studies has been debated in neuropsychology for many years. The purpose of the present study is to illustrate an alternative approach to group studies of aphasia, in which the same symptom dimensions that are commonly used to assign patients to classical taxonomies (fluency, naming, repetition, and comprehension) are used as independent and continuous predictors in a multivariate design, without assigning patients to syndromes. One hundred twenty-six Italian-speaking patients with aphasia were first classified into seven classic aphasia categories, based on fluency, naming, auditory comprehension, and repetition scales. There were two goals: (1) compare group analyses based on aphasia types with multivariate analyses that sidestep classification and treat aphasic symptoms as continuous variables; (2) present correlation-based outlier analyses that can be used to identify individuals who occupy unusual positions in the multivariate "symptom space." In the service of the first goal, group performance on an external validation measure (the Token Test) was assessed in three steps: analyses of variance based on aphasia type, regressions using the same cut-offs for fluency, naming, comprehension and repetition as independent but dichotomous predictors, and regressions using the same subscales as continuous predictors (with no cut-offs). More variance in Token Test performance was accounted for when symptoms were treated as continuous predictors than with the other two methods, though use of independent but dichotomous predictors accounted for more variance than aphasia taxonomies. Thus, if we by-pass classical taxonomies and treat patients as points in a multidimensional symptom space, better predictions are obtained. Outlier analyses show that group results depend on heterogeneity among patients, which can be used as a search tool to identify potentially interesting dissociations. Hence this multivariate group approach is complementary to and compatible with single-case methods.     

Coordinate high-frequency pattern of stimulation and calcium levels control the induction of LTP in striatal cholinergic interneurons

Current evidence appoints a central role to cholinergic interneurons in modulating striatal function. Recently, a long-term potentiation (LTP) of synaptic transmission has been reported to occur in these neurons. The relationship between the pattern of cortico/thalamostriatal fibers stimulation, the consequent changes in the intracellular calcium concentration ([Ca2+]i), and the induction of synaptic plasticity was investigated in striatal cholinergic interneurons from a rat corticostriatal slice preparation by means of combined electrophysiological intracellular recordings and microfluorometric techniques. Different protocols of stimulation were considered, varying both the frequency and the duration of the train of stimuli. High-frequency stimulation (HFS) (three trains at 100 Hz for 3 sec, 20-sec interval) induced a rise in [Ca2+]i, exceeding by fivefold the resting level, and caused a LTP of synaptic transmission. Tetanic stimulation delivered at lower frequencies (5-30 Hz) failed to induce long-term changes of synaptic efficacy. The observed elevation in [Ca2+]i during HFS was primarily mediated by L-type high-voltage activated (HVA)-Ca2+ channels, as it was fully prevented by nifedipine. Conversely, blockade of NMDA and AMPA glutamate receptor did not affect either LTP or the magnitude of the [Ca2+]i rise. Interestingly, the pharmacological analysis of the post-tetanic depolarizing postsynaptic potential (DPSP) revealed that LTP was attributable, to a large extent, to the potentiation of the GABA(A)-mediated component. In conclusion, the expression of LTP in striatal cholinergic interneurons is a selective response to a precise stimulation pattern of induction requiring a critical rise in [Ca2+]i.     

Gender congruence in confirmatory and compensatory drinking.

The relationship between gender-stereotypical traits and drinking behaviors was examined in 422 university students via both positive and negative measures of masculinity and femininity. Two canonical variates summarized the underlying relationships. The 1st canonical variate indicated that both high negative masculinity and low positive femininity predicted alcohol consumption and alcohol-related problems. This behavior was labeled confirmatory drinking because it depicts a style of drinking that reinforces gender-stereotypical images about alcohol use; masculine characteristics are typically associated with high levels of alcohol consumption. The 2nd canonical variate indicated that both low positive masculinity and low positive femininity predicted problem drinking. This behavior was labeled compensatory drinking because drinkers often use alcohol to express their masculinity and femininity. The distinction between confirmatory and compensatory drinking has important implications for the development of more effective education and preventative strategies.     

Role of Sexual Orientation and Gender-Related Traits in Disordered Eating

This study was designed to examine the role of both sexual orientation and gender-related personality traits in disordered eating attitudes and behavior, including body dissatisfaction. Self-report measures assessing negative and positive gender traits,body dissatisfaction, drive for thinness, dietary restraint, and bulimic symptoms were administered to 266 participants (64 lesbians, 73 heterosexual women, 69 gay men, and 60 heterosexual men; 85% Anglo-Australian Caucasians, 15% Caucasians from Non-English-speaking backgrounds). Consistent with previous research, gay men scored significantly higher than heterosexual men on body dissatisfaction and dietary restraint, whereas lesbians scored significantly lower in comparison to the heterosexual women on body dissatisfaction, drive for thinness, dietary restraint, and bulimia. For men, the additional amount of variance accounted by the gender traits was significantly higher than that accounted for by sexual orientation. For the women, the gender traits also accounted for an additional significant amount of variance; however, overall the amount of variance accounted for by sexual orientation was greater. However, for both men and women, irrespective of their sexual orientation, it was higher scores on negative femininity that predicted higher levels of disordered eating. These results are consistent with previous studies that have found support for the femininity hypothesis in disordered eating.     

Discrimination of voice versus place contrasts in aphasia

A phoneme discrimination test based upon CCVC (consonant-consonant-vowel-consonant) syllables was administered to 36 aphasics, 91 brain-damaged subjects, and 42 normal controls, in normal listening conditions. Errors in the discrimination of voice and place contrasts were determined, and the scores (voice-minus-place errors) obtained by the four experimental groups were compared statistically. Aphasic patients, when compared with the other groups, show a greater difficulty in discriminating place than voice contrasts. Some implications of these findings are discussed.     

Social cognition and real-life functioning in patient samples with 22q11.2 deletion syndrome with or without psychosis,compared to a large sample of patients with schizophrenia only and healthy controls

Patients with the 22q11.2 deletion syndrome (DS) show an increased risk of developing a psychotic illness lifetime. 22q11.2DS may represent a reliable model for studying the neurobiological underpinnings of schizophrenia. The study of social inference abilities in a genetic condition at high risk for psychosis, like 22q11.2DS, may shed light on the relationships between neurocognitive processes and patients' daily general functioning. The study sample consisted of 1736 participants, divided into four groups: 22q11.2DS patients with diagnosis of psychotic disorder (DEL SCZ, N = 20); 22q11.2DS subjects with no diagnosis of psychosis (DEL, N = 43); patients diagnosed with schizophrenia without 22q11.2DS (SCZ, N = 893); and healthy controls (HC, N = 780). Social cognition was assessed through The Awareness of Social Inference Test (TASIT) and general functioning through the Specific Levels of Functioning (SLoF) scale. We analysed data through regression analysis. The SCZ and DEL groups had similar levels of global functioning; they both had significantly lower SLoF Total scores than HC (p < .001); the DEL SCZ group showed significantly lower scores compared to the other groups (SCZ, p = .004; DEL, p = .003; HC, p < .001). A significant deficit in social cognition was observed in the three clinical groups. In the DEL SCZ and SCZ groups, TASIT scores significantly predicted global functioning (p < .05). Our findings of social cognition deficit in psychosis-prone patients point to the possible future adoption of rehabilitation programmes, like Social Skills Training and Cognitive Remediation, during premorbid stages of psychosis.     

Critical stages in mental development: Childhood breath holding spells (BHS)

The authors present the first part of a study on children with BHS (Breath Holding Spells) syndrome. These children were chosen in order to examine a “pathological” situation in infancy that was as close as possible to a “normal” one, and in which obvious somatic symptoms were associated with emotional states. Children with BHSS are not considered to have serious psychological disturbances, even if they are constantly referred to as intolerant of separation, stubborn, oppositional, or easy to temper tantrum. A reduced ability to tolerate frustration is evident in these children both from the patients' history and clinical observation. Parents usually relate BHS to situations in which the child is denied something or gets scolded. The children were observed during three sessions, both with and without the mother, according to a grid used at our Center. Patients are presented to illustrate certain recurrent features in play and interaction with mother. The data suggest that these children stagnate in an area of incomplete mental representation; something makes them oscillate between two states; in one of them, the mental representation of the object and of the bond with it is possible; in the other, the mental representation of the separation, which entails the recognition of the object, is felt as dangerous.     

Gender Traits and Self-Concept as Indicators of Problem Eating and Body Dissatisfaction Among Children

The present study was designed to examine the role of gender traits, body mass index (BMI), and self-concept in predicting levels of problem eating and body dissatisfaction among both girls and boys aged between 8 and 10 (85% were Anglo-Australian Caucasian, 15% were Caucasians from non-English backgrounds). Two hundred and two children completed questionnaires, which examined problem-eating attitudes and behaviors, body dissatisfaction, gender traits, and self-concept. Children's height and weight were measured to determine children's BMI. Gender traits predicted problem eating for boys but not for girls. Self-concept was found to predict problem eating for both boys and girls. BMI was also a predictor of problems for girls. The only predictor of body dissatisfaction for boys and girls was BMI. The findings are discussed in light of previous research, which has been conducted, on adolescents. Further studies are needed to understand more fully the development of problem eating and body dissatisfaction before the onset of puberty and adolescence.
