The relationship between employment quality and work-related well-being in the European Labor Force

In this article, data from the 2005 European Working Conditions Survey are used to examine the relationship between contemporary employment arrangements and the work-related well-being of European employees. By means of a Latent Class Cluster Analysis, several features of the employment conditions and relations characterizing jobs are combined in a typology of five employment arrangements: SER-like, instrumental, precarious unsustainable, precarious intensive and portfolio jobs. These job types show clear relationships with separate indicators of job satisfaction, perceived safety climate and the ability to stay in employment, as well as with an overall indicator for work-related well-being. The findings from this multifaceted approach towards employment quality raise questions about the long-term sustainability of highly flexible and de-standardized employment arrangements.     

Functional focal retrograde amnesia: Lost access to abstract autobiographical knowledge?

We describe three patients exhibiting an acute reversible amnesia characterised by an impaired recollection of past events with preserved anterograde memory, thus consistent with a focal retrograde amnesia (FRA). This occurred after variable events: state of fugue, road accident, post-traumatic headache. Retrograde amnesia affected autobiographical memory so severely as to cover all of the patients' lives and to erase knowledge of their own identity. The retrieval of public events was variably affected, ranging from normality to severe impairment. No lesions were found on neuroimaging, and neurophysiological findings were unimpressive. FRA subsided in a few days, leaving a gap for the onset. The hypothesis of a psychogenic amnesia is considered, but overcoming the organic/psychogenic dichotomy the episodes appear as examples of “functional” memory inhibition, potentially triggered by different conditions, including events classifiable as psychic trauma. The clinical and neuropsychological traits of functional FRA are discussed. According to a current theory of autobiographical memory, the memory profile may be explained by a lost access to abstract autobiographical knowledge. Given some analogies with the more common transient global amnesia, a mechanism of spreading depression may also be hypothesised for functional FRA.     

Effects of approach and withdrawal motivation on interactive economic decisions

Although recent economic models of human decision making have recognised the role of emotion as an important biasing factor, the impact of incidental emotion on decisions has remained poorly explored. To address this question, we jointly explored the role of emotional valence (i.e., positive vs. negative) and motivational direction (i.e., approach vs. avoidance) on performance in a well-known economic task, the Ultimatum Game. Participants had to either accept or reject monetary offers from other players, offers that vary in their degree of unfairness. A main effect of motivational direction, but not valence, was observed, with withdrawal-based emotion (disgust and serenity) prompting more rejections relative to approach-based emotion (anger and amusement) and a neutral state. These results further confirm that subtle incidental moods can bias decision making, and suggest that motivational state may be a useful framework to study such decisions. Implications with regard to emotion, cognitive neuroscience, and clinical psychology are discussed.     

Masculinity and Self‐Esteem in Israeli Jewish Professional Women 1

The literature suggests that while women experience unique challenges with self‐esteem and self‐acceptance, Jewish professional women in Israel face additional challenges in balancing majority culture values, ethnic traditions, and the socio‐historical‐political context of the country. The present study investigated differences in masculinity, femininity, locus of control, self‐esteem, and self‐acceptance among Israeli Jewish and other professional women, including professional women scientists. Masculinity scores were significantly lower for Israeli Jewish women, and self‐acceptance scores were significantly lower for Israeli Jewish women than for the group of professional women.     

RSK2 signaling in brain habenula contributes to place aversion learning

RSK2 is a Ser/Thr kinase acting in the Ras/MAPK pathway. Rsk2 gene deficiency leads to the Coffin-Lowry Syndrome, notably characterized by cognitive deficits. We found that mrsk2 knockout mice are unable to associate an aversive stimulus with context in a lithium-induced conditioned place aversion task requiring both high-order cognition and emotional processing. Virally mediated shRNA-RSK2 knockdown in the habenula, whose involvement in cognition is receiving increasing attention, also ablated contextual conditioning. RSK2 signaling in the habenula, therefore, is essential for this task. Our study reveals a novel role for RSK2 in cognitive processes and uncovers the critical implication of an intriguing brain structure in place aversion learning.     

Questioning implicit motor learning as instantiated by the pursuit-tracking task

The effect of concurrent visual feedback on the implicit learning of repeated segments in a task of pursuit tracking has been tested. Although this feedback makes it possible to regulate the positional error during the movement, it could also induce negative guidance effects. To test this hypothesis, a first set of participants (N=42) were assigned to two groups, which performed either the standard pursuit-tracking task based on the experimental paradigm of Pew ( 1974 ; group F-ST), or a task called "movement reproduction" in which the feedback was suppressed (group noF-ST). A second set of participants (N=26) performed in the same feedback condition groups but in a dual-task situation (F-DT and noF-DT; Experiment 2). The results appear to confirm our predictions since the participants in groups without feedback, contrary to those in groups with feedback, succeeded with practice in differentiating their performances as a function of the nature of the segments (repeated or nonrepeated) both in simple (Experiment 1) and in dual-task (Experiment 2) situations. These experiments indicate that the feedback in the pursuit-tracking task induces a guidance function potentially resulting in an easiness tracking that prevents the participants from learning the repetition.     

Prevalence of Internet addiction in Latino adolescents with psychiatric diagnosis

Internet addiction (IA) is particularly relevant in the adolescent population. The aim of this study was to describe the prevalence of IA in a clinical sample of Latino adolescents receiving ambulatory psychiatric treatment. The correlation between their pattern of Internet use and their respective psychiatric diagnosis was also studied. Adolescent patients from the Psychiatric Ambulatory Clinic at the Pediatric University Hospital (N=71) completed the Internet Addiction Test (IAT) and a questionnaire about Internet use. Information regarding demographic and diagnostic data was retrieved from their clinical records. None of the subjects presented severe IA. A total of 71.8% (n=51) of the adolescents obtained scores reflecting no problem related to IA. Only 11.6% (n=5) of subjects have discussed Internet use with their therapist. Mood disorders showed a statistically significant (p=0.044) correlation with a higher score on the IAT. Mental health care practitioners must consider questions on Internet use as an essential part of the patients' evaluation given its significant correlation with diagnosis of a mood disorder.     

Systemic and local administration of estradiol into the prefrontal cortex or hippocampus differentially alters working memory

The influence of estradiol on learning and memory is dependent on a number of factors. The effects of physiological levels of estradiol on the acquisition of a spatial working memory task mediated by the prefrontal cortex (PFC) and the hippocampus were examined in Experiment 1. Ovariectomized Long-Evans rats received daily injections of estradiol or vehicle were tested on the win-shift version of the radial arm maze. A high dose of estradiol benzoate (5 microg) enhanced acquisition of the task, whereas a low dose of estradiol (0.3 microg) increased the number of errors committed over 17 days of testing. Experiment 2 was conducted to examine site-specific influences of estradiol on spatial working memory in well-trained rats. Saline and estradiol cyclodextrin (0.1 and 0.9 microg) were infused into the prelimbic region of the PFC or dorsal hippocampus 40 min prior to testing on the win-shift task. Infusions of estradiol into both brain areas attenuated saline-infusion disruptions in working memory. Specifically, the higher dose of estradiol facilitated working memory when infused into the PFC, whereas the lower dose of estradiol facilitated performance when infused into the dorsal hippocampus. Moreover, working memory was significantly impaired 24 h after infusions of estradiol into the dorsal hippocampus but not the PFC. These data provide further evidence for the notion that estradiol can dose-dependently alter memory processes and suggest that facilitation or disruptions of working memory by estradiol are site- and time-specific.     

No negative semantic priming from unconscious flanker words in sight

In replicating 1 of the within-language conditions of E. Fox's (1996) Experiment 1, the authors confirmed that unattended words presented 2.4 degrees above and below fixation are mostly unavailable to awareness. However, no negative semantic priming was observed in a lexical decision on a probe letter string appearing about 1 s later, which does not replicate Fox's finding. These results are compatible with the hypothesis underlying the present study, according to which positive semantic priming, if any, rather than negative semantic priming is expected in Fox's situation. The reason is that unavailability to awareness of the parafoveal words is not achieved by means of an act of selective inhibition combined with attentional diversion through masking but is achieved simply by means of perceptual degradation.     

Segregation or Integration? Immigrant Self-Employment in Switzerland

This article investigates whether immigrant self-employment is related more to segregation in the labour market than work as an employee (making it justifiable to speak of ethnic business) or whether, on the contrary, it reflects equality with the self-employment by the Swiss. The distinctive features of this research design are the comparison of ethnic segregation in the labour market with gender-specific segregation and the fact that, apart from migrants of the first generation, members of the second generation are also taken into consideration. The analyses show, firstly, that large differences exist between the various groups of migrants and that three patterns in immigrant self-employment become apparent. While for one person self-employment brings greater adjustment to the Swiss in comparison with working as an employee, for another it is associated with greater segregation. The third pattern reveals that self-employment can be an expression of “superstratification” (Überschichtung). Secondly, the analyses indicate that, for the self-employed, gender-specific horizontal and vertical segregation tends to be smaller than for employees. However, in the upper positions of the social space, greater gender-specific inequalities can be observed than in the lower positions, thus making “class” and “gender” intersect as structural categories of social inequality.
