Internalising symptoms and verbal working memory in school‐age children: A processing efficiency analysis

The current study investigated differential contributions of internalising symptoms (state anxiety, trait anxiety, depression) to school‐age children's verbal short‐term (STM) and working memory (WM) span accuracy and efficiency (microanalysis of response times). Children's (N = 125, M_age = 11.44 years) STM/WM was assessed with simple/complex span tasks. Our analyses revealed that: (a) children with high levels of state anxiety displayed reduced simple span accuracy (on Word span) and poorer efficiency on both simple (preparatory intervals, interword pauses) and complex span (preparatory intervals) response time segments; (b) trait anxiety was a negative predictor of children's complex span accuracy, as well as their efficiency on both simple (word durations) and complex span (interword pauses) response time measures; (3) depressive symptoms predicted longer simple span interword pauses. Findings indicate that while all internalising symptoms were predictive of children's poorer memory search efficiency, especially during the “silent”, executive intervals (interword pauses), anxiety symptoms were specifically predictive of children's impaired span accuracy and other efficiency indicators (preparatory intervals, word durations). The study highlights the differential contributions of state, trait anxiety, and depressive symptoms to STM/WM in children, emphasising the need to measure both accuracy and efficiency to assess the role that such symptoms play in children's performance.     

Evidence‐Based Human Trafficking Policy: Opportunities to Invest in Trauma‐Informed Strategies

Human trafficking is a critical social issue characterized by chronic trauma among victims, and frequently preceded by traumatic experiences that contribute to risk of victimization. Therefore, the research‐based practice of trauma‐informed care is a highly appropriate lens for both prevention and intervention. This work examines federal legislation in the United States related to human trafficking for references to trauma, as well as how the use of research could implicitly direct public policy responses toward trauma‐informed approaches. Legislation on human trafficking has risen substantially since 1989, and the use of research and trauma language within these policies has also observed substantial increases. While the use of trauma language was associated with limited progression in the policy process, legislation using research language was more likely to pass out of Committee and become enacted. Moreover, legislation may leverage research in ways that have the potential to bolster trauma‐informed practice among human trafficking victims. Specifically, research can be used to describe the problem and causal mechanisms (e.g., impact of trauma), guide “best practice” for service delivery, and generate knowledge through studies and evaluations that guide future policy. Therefore, human trafficking legislation that implicitly guides trauma‐informed practice via the use of research may be particularly promising for the field.     

Individual Differences in Habitual Social Goals and Daily Well‐Being: The Role of Age and Relationship Closeness

There is a robust evidence that social approach goals (i.e. approach of positive social outcomes) have positive consequences and social avoidance goals (i.e. avoidance of negative social outcomes) have negative consequences for subjective well‐being in young adulthood. Little is known about individual differences in social goals in later life. The current diary study with young (n = 212), middle‐aged (n = 232), and older adults (n = 229) tested––and supported––the hypotheses that age (i) differentially predicts the strength of habitual approach and avoidance goals in close and peripheral relationships and (ii) moderates the relation of approach and avoidance goals in peripheral (but not close) relationships and daily outcomes (subjective well‐being, subjective health, and satisfaction with social encounters). Older adults compared to younger adults reported higher levels of avoidance goals in peripheral (but not close) relationships. Younger adults who reported high levels of approach goals and older adults who reported high levels of avoidance goals in peripheral relationships experienced the most positive daily outcomes. In addition, social goals moderated some of the associations between (positive and negative) daily interactions and daily outcomes. Results underscore the importance of the closeness of social partners for individual differences in social goals across adulthood. © 2019 European Association of Personality Psychology     

Semantic interference on a phonological task in illiterate subjects

Previous research suggests that learning an alphabetic written language influences aspects of the auditory-verbal language system. In this study, we examined whether literacy influences the notion of words as phonological units independent of lexical semantics in literate and illiterate subjects. Subjects had to decide which item in a word- or pseudoword pair was phonologically longest. By manipulating the relationship between referent size and phonological length in three word conditions (congruent, neutral, and incongruent) we could examine to what extent subjects focused on form rather than meaning of the stimulus material. Moreover, the pseudoword condition allowed us to examine global phonological awareness independent of lexical semantics. The results showed that literate performed significantly better than illiterate subjects in the neutral and incongruent word conditions as well as in the pseudoword condition. The illiterate group performed least well in the incongruent condition and significantly better in the pseudoword condition compared to the neutral and incongruent word conditions and suggest that performance on phonological word length comparisons is dependent on literacy. In addition, the results show that the illiterate participants are able to perceive and process phonological length, albeit less well than the literate subjects, when no semantic interference is present. In conclusion, the present results confirm and extend the finding that illiterate subjects are biased towards semantic-conceptual-pragmatic types of cognitive processing.     

The behavioral effects of enriched housing are not altered by serotonin depletion but enrichment alters hippocampal neurochemistry

To assess a possible role for serotonin in the mediation of the behavioral changes induced by enriched housing conditions (EC), adult female Long-Evans rats sustaining a serotonin depletion (150 microg of 5,7-dihydroxytryptamine, icv) and sham-operated rats were housed postoperatively for 30 days in enriched (12 rats/large cage containing various objects) or standard housing conditions (2 rats/standard laboratory cage). Thereafter, anxiety responses (elevated plus-maze), locomotor activity (in the home-cage), sensori-motor capabilities (beam-walking task), and spatial memory (eight-arm radial maze) were assessed. Monoamine levels were subsequently measured in the frontoparietal cortex and the hippocampus. Overall, EC reduced anxiety-related responses, enhanced sensori-motor performance and improved the memory span in the initial stage of the spatial memory task. Despite a substantial reduction of serotonergic markers in the hippocampus (82%) and the cortex (74%), these positive effects of EC were not altered by the lesion. EC reduced the serotonin levels in the ventral hippocampus (particularly in unlesioned rats: -23%), increased serotonin turnover in the entire hippocampus (particularly in lesioned rats: +36%) and augmented the norepinephrine levels in the dorsal hippocampus (+68% in unlesioned and +49% in lesioned rats); no such alterations were found in the frontoparietal cortex. Our data suggest that an intact serotonergic system is not a prerequisite for the induction of positive behavioral effects by EC. The neurochemical changes found in the hippocampus of EC rats, however, show that the monoaminergic innervation of the hippocampus is a target of EC.

Middle school student perceptions of school climate: Examining protective functions on subsequent adjustment problems

The present study examined the roles of student perceptions of four aspects of school climate (friction, cohesion, competition among students, and satisfaction with classes) as moderators of the relations between effortful control and subsequent conduct problems and depressive symptoms. Participants were 488 10-to-14-year old students involved in two waves, with one year between each wave, of a study. Hierarchical regression analyses indicated that high levels of perceived friction predicted more subsequent conduct problems and depressive symptoms, even after baseline levels of these problems were partialled out. Low levels of effortful control also elevated risk for subsequent conduct problems. However, perceptions of the school as high in cohesion offset the risk associated with low levels of effortful control. Perceived satisfaction with classes also offset this risk, but only for females. Contrary to expectations, student perceptions of school climate did not interact with effortful control to predict subsequent depressive symptoms.     

Interference and facilitation among personal goals: differential associations with subjective well-being and persistent goal pursuit

Three studies demonstrate that mutual facilitation and interference among personal goals are distinct characteristics rather than mutually exclusive opposites and have different functions for psychological well-being and goal pursuit. The three studies vary in design (cross-sectional, short-termlongitudinal) and follow a multimethod approach using questionnaires, diaries, and objective behavioral information. Results show that interference among goals (resulting from resource constraints and incompatible goal attainment strategies) is negatively associated with trait and state well-being, whereas mutual facilitation among goals (resulting from instrumental goal relations and overlapping goal attainment strategies) is positively associated with involvement in goal pursuit.
