Differential susceptibility in spillover between interparental conflict and maternal parenting practices: evidence for OXTR and 5-HTT genes

Guided by the affective spillover hypothesis and the differential susceptibility to environmental influence frameworks, the present study examined how associations between interparental conflict and mothers' parenting practices were moderated by serotonin transporter (5-HTT) and oxytocin receptor (OXTR) genes. A sample of 201 mothers and their 2-year old child participated in a laboratory-based research assessment. Results supported differential susceptibility hypotheses within spillover frameworks. With respect to OXTR rs53576, mothers with the GG genotype showed greater differential maternal sensitivity across varying levels of interparental conflict. Mothers with one or two copies of the 5-HTTLPR S allele demonstrated differential susceptibility for both sensitive and harsh/punitive caregiving behaviors. Finally, analyses examined whether maternal depressive symptoms and emotional closeness to their child mediated the moderating effects. Findings suggest that maternal emotional closeness with their child indirectly linked OXTR with maternal sensitivity. The results highlight how molecular genetics may explain heterogeneity in spillover models with differential implications for specific parenting behaviors. Implications for clinicians and therapists working with maritally distressed parents are discussed.     

Neural control of voluntary eye closure: a case study and an fMRI investigation of blinking and winking

The current paper describes a rare case of a patient who suffered from unilateral apraxia of eye closure as a result of a bilateral stroke. Interestingly, the patient's ability to voluntarily close both eyelids (i.e. blinking) was not affected, indicating that different neural mechanisms control each type of eye closure. The stroke caused damage to a large part of the right frontal cortex, including the motor cortex, pre-motor cortex and the frontal eye field (FEF). The lesion in the left hemisphere was restricted to the FEF. In order to further study the neural mechanisms of eye closure, we conducted an fMRI study in a group of neurological healthy subjects. We found that all areas of the oculomotor cortex were activated by both left and right winking, including the FEF, supplementary eye field (SEF), and posterior parietal cortex (PPC). Blinking activated FEF and SEF, but not PPC. Both FEF and PPC were significantly more active during winking than blinking. Together, these results provide evidence for a critical role of the FEF in voluntary unilateral eye closure.     

Assessing Diagnostic Expertise of Counselors Using the Cochran–Weiss–Shanteau (CWS) Index

Counseling studies have shown that increasing experience is not always associated with better judgments. However, in such studies performance is assessed against external criteria, which may lack validity. The authors applied the Cochran–Weiss–Shanteau (CWS) index, which assesses the ability to consistently discriminate. Results showed that novice counselors performed almost on the same level as very experienced counselors. The authors thus replicated earlier findings with a novel approach: applying an internal coherence criterion.     

Psychometric Evaluation of the Factor Structure of the Teasing Questionnaire – Revised (TQ-R)

Recent literature has focused on the relation between childhood teasing and adulthood psychopathology, with the majority of this work dependent on a single measure, the Teasing Questionnaire-Revised (TQ-R; Storch et al. Journal of Anxiety Disorders 18:681–694, 2004). However, the factor structure and reliability of the TQ-R requires further examination. The present investigation reevaluated the factor structure of the TQ-R in two large samples. In Study 1, three previous factor models were investigated through confirmatory factor analyses (CFAs) in a large clinical sample. Due to their poor fit, exploratory factor analyses (EFAs) were used to investigate alternative factor models. In Study 2, the factor structure of the previous models and new models from Study 1 EFAs were investigated through CFAs and estimates of internal consistency in a large college sample. Together, these findings provided the most support for a new 21-item five factor model, identified in the Study 1 EFAs and supported by the Study 2 CFAs, with the content of the teasing subscales consistent with the constructs of anxiety, appearance, academics, weight, and height.     

Linderung depressiver Symptomatik

Standard interventions, such as antidepressive medication or psychotherapy, show only medium effect sizes in the reduction of depressive symptomatology. In addition, medication has problematic and not well accepted side-effects therefore it seems reasonable to look for alternative, cost-effective, easily available treatments which show no side-effects. A large number of studies have demonstrated similar neurophysiological effects of sport as antidepressants or psychotherapies but the crucial question remains unanswered: does sport show antidepressive effects by alleviating depressive symptomatology? Some randomized, controlled studies and all available recent meta-analysis addressing this question are reviewed. This review concludes that randomized control trials including sport activities have similar positive effect sizes as psychotherapy or antidepressant studies. The pre-post effects are in the medium to high range. Such a conclusion is jeopardized by a limited number of methodolically sound studies. It is too early to make evidence-based recommendations about the antidepressive effect of sport. Currently, it can only be speculated about moderators and mechanisms mediating outcome.     

Non‐standard work schedules and retention in the entry‐level hourly workforce

Non‐standard work schedules involve work outside the Monday–Friday daytime hours. Although research has heavily studied the health and family effects of such schedules, few studies have investigated their relationship to retention. We draw from Maertz and Campion's discussion of motivational forces that influence turnover to propose that employees on non‐standard schedules are more likely to quit their employer because of general job dissatisfaction and because of normative pressures from family and/or friends. Specifically, we hypothesized that employees on day shifts or weekday only schedules would remain with their employer longer than those who work on nonday shifts or on the weekends. We also hypothesized that perceived employment mobility would moderate the effects of non‐standard schedules on retention length. Hypotheses were tested among 3,178 retail employees who worked five different distinct shift arrangements and different weekday/weekend schedules. Cox regression analyses indicated that, as hypothesized, employees working nonday shifts or schedules including weekends remained with their employer for a shorter duration of time than employees not on such schedules. Perceived mobility moderated the schedule–turnover relationship, though not in the hypothesized manner. We discuss the theoretical and practical implications of these findings for work schedule assignment and retention strategies.     

Defining the Role of Laboratory Genetic Counselor

An increasing number of genetic counselors are moving into non-clinical roles, where their primary duties do not involve direct patient contact. According to the National Society of Genetic Counselors Professional Status Survey in 2010, 23% of counselors working in non-clinical roles identified laboratory or genetic testing as their primary area of work. Using a survey, we identified 43 genetic counselors who work predominately in laboratory settings. The two primary tasks performed by participants, include acting as a customer liaison (95%) and calling out test results (88%). Nineteen participants (44.2%) also reported spending a considerable amount of time signing reports. The most prevalent areas of job satisfaction were support from laboratory directors (76.8%), autonomy (76.7%), interactions with clinicians (69.7%) and interaction with other genetics counselors (67.5%). This is the first study specifically looking at the roles of laboratory genetic counselors, which is an expanding area of genetic counseling.     

Learning new vocabulary in German: the effects of inferring word meanings,type of feedback,and time of test

In the present study, introductory-level German students read a simplified story and learned the meanings of new German words by reading English translations in marginal glosses versus trying to infer (i.e., guess) their translations. Students who inferred translations were given feedback in English or in German, or no feedback at all. Although immediate retention of new vocabulary was better for students who used marginal glosses, students who inferred word meanings and then received English feedback forgot fewer translations over time. Plausible but inaccurate inferences (i.e., those that made sense in the context) were more likely to be corrected by students who received English feedback as compared with German feedback, providing support for the beneficial effects of mediating information. Implausible inaccurate inferences, however, were more likely to be corrected on the delayed vocabulary test by students who received German feedback as compared with English feedback, possibly because of the additional contextual support provided by German feedback.     

Semantic picture-word interference is a postperceptual effect

Naming a picture is slower while ignoring a semantically related versus an unrelated distractor word (semantic picture–word interference, or PWI). To locate the PWI effect in the word production processing stream (during perceptual encoding, response selection, or afterward), we used the psychological refractory period paradigm, in which participants identified a tone and then, at varying SOAs, named a picture while ignoring a semantically related or unrelated word (following Dell’Acqua, Job, Peressotti, & Pascali, 2007). As in results from the Stroop paradigm (Fagot & Pashler, 1992), we found equivalent PWI effects at short and long SOAs following tone identification in two experiments, indicating that semantic competition occurs at response selection or later. Our results suggest that it is premature to assume that competitive selection occurs at multiple levels in the word production system (van Maanen, van Rijn, & Borst, 2009) or that the Stroop and semantic PWI effects are fundamentally different (Dell’Acqua et al., 2007).
