Children’s Post-Divorce Living Arrangements and School Engagement: Financial Resources,Parent–Child Relationship,Selectivity and Stress

Children’s post-divorce living arrangements have become increasingly heterogeneous the past decades, because of the rise in shared residence and stepfamily formation. This study investigates how post-divorce living arrangements (i.e. the combination between residential arrangement and stepparent presence) are related to children’s school engagement. The focus is put on different explanations of the relation between living arrangements and school engagement, namely financial resources, parent–child relationship, selectivity and stress. Structural equation models are performed on a sample of children with divorced parents from the Leuven Adolescent and Family Study data 2008–2011 (n?=?1630). First, the results show that stepfamilies have higher financial resources than single-parent families, but these higher financial resources are not directly related to children’s school engagement. Second, parent–child relationship is an important mediator between post-divorce living arrangements and school engagement. The results suggest that shared residence is related to a better fatherchild relationship and in this manner improves school engagement. The relation between stepparent presence and the parent–child relationship is less straightforward, and the findings suggest that the combination of residential arrangement, stepfather and stepmother presence should be taken into account. Third, children’s sociodemographic characteristics, time since divorce and level of pre-divorce conflict function as selection mechanisms, as they are related to both post-divorce living arrangements and children’s school engagement. Finally, the findings indicate that the complexity of multiple part-time residential figures is stressful to children. This may partially counterbalance the benefits of such systems, via the better parent–child relationship and the higher financial resources.     

Psychometric evaluation of the Dutch translation of the Overall Assessment of the Speaker's Experience of Stuttering for adults (OASES-A-D)

The Overall Assessment of the Speaker's Experience of Stuttering for adults (OASES-A; [Yaruss and Quesal, 2006] and [Yaruss and Quesal, 2010]) is a patient-reported outcome measure that was designed to provide a comprehensive assessment of “the experience of the stuttering disorder from the perspective of individuals who stutter” (Yaruss & Quesal, 2006, p. 90). This paper reports on the translation process and evaluates the psychometric performance of a Dutch version of the OASES-A. Translation of the OASES-A into Dutch followed a standard forward and backward translation process. The Dutch OASES-A (OASES-A-D) was then administered to 138 adults who stutter. A subset of 91 respondents also evaluated their speech on a 10-point Likert scale. For another subset of 45 respondents, a clinician-based stuttering severity rating on a 5-point Likert scale was available. Thirty-two of the respondents also completed the Dutch S-24 scale (Brutten & Vanryckeghem, 2003). The OASES-A-D showed acceptable item properties. No ceiling effects were observed. For 30 out of 100 items, most of which were in Section IV (Quality of Life), floor effects were observed. Cronbach's α coefficients for all sections and subsections surpassed the 0.70 criterion of good internal consistency and reliability. Concurrent validity was moderate to high. Construct validity was confirmed by distinct scores on the OASES-A-D for groups with different levels of stuttering severity as rated by the speakers themselves or by clinicians. These results suggest that the OASES-A-D is a reliable and valid measure that can be used to assess the impact of stuttering on Dutch adults who stutter.Educational objectives: The reader will be able to: (a) describe the purpose of the Overall Assessment of the Speaker's Experience of Stuttering for adults (OASES-A) measurement tool; (b) summarize the translation process used in creating the Dutch version of the OASES-A (OASES-A-D); (c) evaluate the psychometric properties of the OASES-A-D; and (d) compare the psychometric properties of the OASES-A-D with those of the original American English OASES-A.     

Weekly work engagement and performance: A study among starting teachers

This study among 54 Dutch teachers tested a model of weekly work engagement. On the basis of theories about the motivational potential of job resources, we predicted that teachers' weekly job resources are positively related to their week‐levels of work engagement, and that week‐level work engagement is predictive of week‐level performance. In addition, we hypothesized that momentary work engagement has a positive, lagged effect on next week's job resources. Teachers were asked to fill in a weekly questionnaire every Friday during 5 consecutive weeks. Results of multi‐level analyses largely confirmed our hypotheses, by showing that week‐levels of autonomy, exchange with the supervisor, and opportunities for development (but not social support) were positively related to weekly engagement, which, in turn, was positively related to weekly job performance. Moreover, momentary work engagement was positively related to job resources in the subsequent week. These findings show how intra‐individual variability in employees' experiences at work can explain weekly job performance.     

Waiting impulsivity: a distinctive feature of ADHD neuropsychology?

Impulsivity is a core feature of attention-deficit hyperactivity disorder (ADHD). It has been conceptualized in a number of different ways. In the current article, we examine how the new concept of “waiting impulsivity”, which refers to premature responding before a scheduled target appears, adds to our understanding of impulsivity in ADHD. Sixty children (8–12 years old; 30 ADHD; 30 typically developing controls) completed the 4-choice serial reaction time task, a measure of waiting impulsivity, alongside tasks measuring inhibitory control and temporal discounting and questionnaires measuring behavioral disorder symptoms, delay aversion, and various aspects of impulsivity. A multiple logistic regression model was used to explore the contribution of the primary task outcomes to predict group membership. Children with ADHD displayed more waiting impulsivity and less inhibitory control; they did not differ in temporal discounting. There was no correlation between waiting impulsivity and inhibitory control. Waiting impulsivity was correlated with parent-reported ratings of hyperactivity/impulsivity, inattention, oppositional defiant disorder (ODD), and conduct disorder (CD) and with self-reported delay aversion ratings. Only waiting impulsivity was a significant predictor of ADHD status. In conclusion, waiting impulsivity is distinct from inhibitory control deficits and predicts ADHD status independently of it. Future research needs to examine the relationship with delay aversion and ODD/CD more thoroughly.     

Haptic orientation perception benefits from visual experience: evidence from early-blind, late-blind, and sighted people

Early-blind, late-blind, and blindfolded sighted participants were presented with two haptic allocentric spatial tasks: a parallel-setting task, in an immediate and a 10-sec delay condition, and a task in which the orientation of a single bar was judged verbally. With respect to deviation size, the data suggest that mental visual processing filled a beneficial role in both tasks. In the parallel-setting task, the early blind performed more variably and showed no improvement with delay, whereas the late blind did improve, but less than the sighted did. In the verbal judgment task, both early- and late-blind participants displayed larger deviations than the sighted controls. Differences between the groups were absent or much weaker with respect to the haptic oblique effect, a finding that reinforces the view that this effect is not of visual origin. The role of visual processing mechanisms and visual experience in haptic spatial tasks is discussed.     

On Association Coefficients for 2×2 Tables and Properties That Do Not Depend on the Marginal Distributions

We discuss properties that association coefficients may have in general, e.g., zero value under statistical independence, and we examine coefficients for 2×2 tables with respect to these properties. Furthermore, we study a family of coefficients that are linear transformations of the observed proportion of agreement given the marginal probabilities. This family includes the phi coefficient and Cohen’s kappa. The main result is that the linear transformations that set the value under independence at zero and the maximum value at unity, transform all coefficients in this family into the same underlying coefficient. This coefficient happens to be Loevinger’s H.     

The influence of facial attractiveness on imitation

People judge, evaluate, and treat attractive people better than moderately attractive or unattractive people [Langlois, J. H., Kalakanis, L., Rubenstein, A. J., Larson, A., Hallam, M., & Smoot, M. (2000). Maxims or myths of beauty? A meta-analytic and theoretical review. Psychological Bulletin, 126, 390–423]. The fact that individuals like attractive people combined with the finding that individuals imitate the ones they like, suggests that they may be more prone to imitate attractive people. The present research extends previous work on attractiveness and imitation by examining this hypothesis. Using a novel coloring procedure, we show that attractive females are imitated more than unattractive females (Experiment 1) and that attractive males are imitated more than unattractive males (Experiment 2). Importantly, this imitation occurs without any direct or anticipated contact with the target individual and without awareness of the influence of attractiveness on imitation behavior.     

Effects of social value orientation on expecting and learning others' orientations

The influence of an individual's own social value orientation on the orientation expected from others and on the learning of others' social orientations was examined. The subjects (N = 148) were classified according to theirown social value orientation. The orientations they generally expected from others were assessed as well. Each subject learned the choices of five other persons, representing the orientations altruism, cooperation, equality, individualism, and competition. With respect to subjects' expectations of others' orientations the triangle hypothesis was not fully supported: only individualists expected their orientation in high frequencies. The false consensus hypothesis received more support. Generally an orientation was expected more frequently by subjects who themselves had that particular orientation than by subjects with other orientations. With regard to the learning of others' orientations support was found for the predictions derived from the triangle and the false consensus hypothesis. Cooperators and individualists were the best overall learners, followed by egalitarian and maximum subjects, and at the lowest level competitors. In addition, nearly every orientation was learned better by subjects who had that orientation than by subjects with a different orientation.     

Causal attribution and self-justification as explanations for the consensus expectation of one's social value orientation

This study focuses on explanations for the perceived consensus of one's own social value orientation. The prediction of the triangle hypothesis that the consensus expectation of individualistic and competitive people is higher than that of cooperative people was partially supported. Only individualists expected their own orientation more frequently of other people. According to a causal attribution explanation, it was expected that subjects' causal attributions for their own orientation to internal and external causes influenced their consensus expectations. Only attributions to internal causes differed significantly between subjects with different orientations and corresponded with their consensus estimates. Individualism was attributed least internally, cooperation most internally, and competition in between. Additionally, direct support for the effect of internal attributions on consensus expectations was found. Compared with subjects who attributed their own orientation more internally, subjects who attributed it less internally were more likely to expect their own orientation among other people. According to a self-justification explanation, it was hypothesized that the consensus expectations of individualists and competitors would be higher when first their own social orientation was assessed and then the orientation they expected to predominate among others than in the reversed order. This hypothesis was not supported.     

Individual differences in dopamine efflux in nucleus accumbens shell and core during instrumental learning

Combined activation of dopamine D1- and NMDA-glutamate receptors in the nucleus accumbens has been strongly implicated in instrumental learning, the process in which an individual learns that a specific action has a wanted outcome. To assess dopaminergic activity, we presented rats with two sessions (30 trials each) of a one-lever appetitive instrumental task and simultaneously measured dopamine efflux in the shell and core accumbens subareas using in vivo microdialysis. Dopamine efflux was increased during each session in all areas. The behavioral performance of the rats in the second session led us to divide them into a learning group (>90% correct trials) and a non-learning group. In the first session, the rats of the learning group showed significantly higher increases. The difference was most pronounced in the shell. In the second session, the dopamine increase was similar in both groups, although the learning groups now pressed the lever about three times more often and consequently obtained more rewards. We conclude that task-related activation of dopamine efflux is different between learning and non-learning rats only during the learning phase. These results support the pharmacological evidence that dopamine is of particular importance during the instrumental learning process.
