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.     

Are some video games associated with more life interference and psychopathology than others? Comparing massively multiplayer online role‐playing games with other forms of video game

Massively multiplayer online role‐playing games (MMORPGs) are a type of video game that is considered to have particular potential to be associated with life interference and psychopathology when played frequently and intensively. This study sought to compare players of MMORPGs with players of other types of video game in terms of problematic use, life interference, and levels of psychopathology. An international sample of 1,945 video game players completed a series of questionnaires online. While MMORPG players reported increased rates of problematic use and life interference compared with non‐MMORPG players, there were no differences in levels of psychopathology. Differences between MMORPG players and non‐MMORPG players appeared to be associated with the increased amounts of time that MMORPG players played for: The amount of time spent playing appeared to mediate the relationships between type of game played and each of the problematic use and life interference variables. The implications of these findings are discussed.     

Two mutations preventing PDZ-protein interactions of GluR1 have opposite effects on synaptic plasticity

The regulated trafficking of GluR1 contributes significantly to synaptic plasticity, but studies addressing the function of the GluR1 C-terminal PDZ-ligand domain in this process have produced conflicting results. Here, we resolve this conflict by showing that apparently similar C-terminal mutations of the GluR1 PDZ-ligand domain result in opposite physiological phenotypes during activity- and CamKII-induced synaptic plasticity.     

Aripiprazole-related tardive dyskinesia

The low prevalence of extrapyramidal symptoms associated with atypical antipsychotics has led to their widespread use during the past decade. Aripiprazole, the newest medication in this class, has been associated with extrapyramidal symptoms (eg, akathisia) and with improvement of tardive dyskinesia (TD), but to date it has not been associated with the development of TD. We report a case of TD associated with the use of aripiprazole 15 mg/day for 18 months for refractory depression. Symptoms of TD resolved within several weeks of discontinuation of aripiprazole.     

The effects of childbirth-related post-traumatic stress disorder on women and their relationships: a qualitative study

There is converging evidence that 1%-2% of women develop post-traumatic stress disorder (PTSD) as a result of childbirth. The current study aimed to explore the long-term effects of childbirth-related PTSD on women, their relationship with their partner and their relationship with their child. Semi-structured interviews were carried out with six women who reported clinically significant PTSD after birth, ranging from 7 months to 18 years beforehand. Interviews were transcribed and analysed using thematic analysis. Childbirth-related PTSD was found to have wide-ranging effects on women and their relationships. Women reported changes in physical well-being, mood and behaviour, social interaction, and fear of childbirth. Women reported negative effects on their relationship with their partner, including sexual dysfunction, disagreements and blame for events of birth. The mother-baby bond was also seriously affected. Nearly all women reported initial feelings of rejection towards the baby but this changed over time. Long-term, women seemed to have either avoidant or anxious attachments with their child. It is concluded that childbirth-related PTSD can have severe and lasting effects on women and their relationships with their partner and children. Further research is needed to compare this to normal difficulties experienced by women after having children.     

Young children's use of a delayed video representation to solve a retrieval problem pertaining to self

The experiments reported here were concerned with the development of delayed self-recognition. Children were videotaped playing a game and were marked covertly with a sticker on their forehead while doing so. The findings, of both a cross-sectional sample and a prospective longitudinal one, revealed that 3- but not 2.5-year-old children reached to remove this sticker reliably during video playback only after they had been trained to use the video to guide their search for an object that was not directly visible to the unaided eye. It appears that by 3 years of age children understand that their briefly delayed self video-representation is related to their present self. In contrast, while 2.5-year-olds can use delayed video information to locate objects in space that cannot be seen by the unaided eye, they cannot use this type of information to locate an object that pertains to a part of self that is not directly visible, such as a sticker on one's hair. The findings are discussed in terms of the emergence of an extended sense of self.     

Executive functions and achievements in school: Shifting, updating, inhibition, and working memory

Links have recently been established between measures of educational attainment and both verbal and visuo-spatial aspects of working memory. Relationships have also been identified between specific executive functions—shifting, updating, and inhibition—and scholastic achievement. In the present study, scholastic attainment, shifting, updating, inhibition, and verbal and visuo-spatial working memory were assessed in 11- and 12-year-old children. Exploratory factor analysis identified two executive factors: one associated with updating functions and one associated with inhibition. Updating abilities were closely linked with performance on both verbal and visuo-spatial working memory span tasks. Working memory was closely linked with attainment in English and mathematics, and inhibition was associated with achievement in English, mathematics, and science. Domain-specific associations existed between verbal working memory and attainment in English, and between visuo-spatial working memory and attainment in English, mathematics and science. Implications of the findings for the theoretical analysis of executive functioning, working memory and children's learning are discussed.     

Hedonic and sensory characteristics of odors conditioned by pairing with tastants in humans

Animals readily acquire positive odor-taste hedonic associations, but evidence for this in humans remains weak and was explored further. Retronasal pairing of odors with sucrose or salty stimuli (Experiment 1) increased the rated sweetness of sucrose-paired odors without altering liking, although changes in odor pleasantness correlated with sucrose liking. Experience of odors with sucrose or quinine by sweet likers (Experiment 2) found increased pleasantness and sweetness for sucrose-paired odors, whereas quinine-paired odors became less liked and more bitter. Odor-sucrose pairings in sweet likers and dislikers (Experiment 3) found increased sweetness in both groups but increased odor liking only in likers. These data suggest that evaluative and sensory learning are dissociable and that evaluative changes are sensitive to individual differences in sweet liking.     

Interruption of the Tower of London task: support for a goal-activation approach

Unexpected interruptions introduced during the execution phase of simple Tower of London problems incurred a time cost when the interrupted goal was retrieved, and this cost was exacerbated the longer the goal was suspended. Furthermore, time taken to retrieve goals was greater following a more complex interruption, indicating the processing limitations may be as important as time-based limitations in determining the ease of goal retrieval. Such findings cannot simply be attributed to task-switching costs and are evaluated in relation to current models of goal memory (E. M. Altmann & G. J. Trafton, 2002; J. R. Anderson & S. Douglass, 2001), which provide a useful basis for the investigation and interpretation of interruption effects.
