Napping reduces emotional attention bias during early childhood

Sleep loss alters processing of emotional stimuli in preschool‐aged children. However, the mechanism by which sleep modifies emotional processing in early childhood is unknown. We tested the hypothesis that a nap, compared to an equivalent time spent awake, reduces biases in attention allocation to affective information. Children (n = 43; M = 55.40 months, SD = 8.05 months) completed a Dot Probe task, which provides a measure of attention biases to emotional stimuli, following a mid‐day nap and an equivalent interval spent awake. No emotional attention biases emerged when children napped. However, when nap‐deprived, children exhibited biases towards negative and positive stimuli. This emotional bias after wake was greater in children who napped habitually. Gender differences also emerged such that females were more attentive to positive emotional stimuli whereas males showed heightened attention to negative emotional stimuli, regardless of having napped or not. Moreover, greater slow wave activity (SWA) during the nap was associated with faster responding, which suggests that SWA may promote efficiency of attention allocation.

Mountain high, valley low: direction-specific effects of articulation on reaching

Representations underpinning action and language overlap and interact very closely. There are bidirectional interactions between word and action comprehension, semantic processing of language, and response selection. This study extends our understanding of the influence of speech on concurrent motor execution. Participants reached-to-grasp the top or bottom of a vertically oriented bar in response to the location of a word on a computer screen (top/bottom). Words were synonyms for "up" or "down", and participants were required to articulate the word during movement. We were particularly interested in the influence of articulated word semantics on the transport component of the reach. Using motion capture to analyse action kinematics, we show that irrespective of reach direction, saying "up" synonyms led to greater height of the hand, while saying "down" synonyms was associated with reduced height. This direction-specific influence of articulation on the spatial parameters of the hand supports the idea that linguistic systems are tightly integrated and influence each other.     

Test-retest reliability and practice effects of the Wechsler Memory Scale-III

Although serial administration of cognitive tests is increasingly common, there is a paucity of research on test-retest reliabilities and practice effects, both of which are important for evaluating changes in functioning. Reliability is generally conceptualized as involving short-lasting changes in performance. However, when repeated testing occurs over a period of years, there will be some longer lasting effects. The implications of these longer lasting effects and practice effects on reliability were examined in the context of repeated administrations of the Wechsler Memory Scale-III in 339 community-dwelling women aged 40-79 years over 2 to 7 years. The results showed that Logical Memory and Verbal Paired Associates subtests were consistently the most reliable subtests across the age cohorts. The magnitude of practice effects varied as a function of subtests and age. The largest practice effects were found in the youngest age cohort, especially on the Faces, Logical Memory, and Verbal Paired Associates subtests.     

Self-generated cognitive fluency as an alternative route to preference formation

People tend to prefer fluently processed over harder to process information. In this study we examine two issues concerning fluency and preference. First, previous research has pre-selected fluent and non-fluent materials. We did not take this approach yet show that the fluency of individuals’ idiosyncratic on-line interactions with a given stimulus can influence preference formation. Second, while processing fluency influences preference, the opposite also may be true: preferred stimuli could be processed more fluently than non-preferred. Participants performed a visual search task either before or after indicating their preferred images from an array of either paintings by Kandinsky or decorated coffee mugs. Preferred stimuli were associated with fluent processing, reflected in facilitated search times. Critically, this was only the case for participants who gave their preferences after completing the visual search task, not for those stating preferences prior to the visual search task. Our results suggest that the spontaneous and idiosyncratic experience of processing fluency plays a role in forming preference judgments and conversely that our first impressions of preference do not drive response fluency.     

Nothing gained: An explorative study of the long‐term effects of perceived maternal feeding practices on women's and men's adult BMI,body image dissatisfaction,and disordered eating

The objective of the studies presented here was the prediction of adult body mass index (BMI), body image dissatisfaction, and disordered eating from recalled maternal child feeding practices. Studies 1 and 2 sampled women from the community, and found that recalled childhood feeding practices predicted both current BMI and current disordered eating. Daughters whose mothers pressured them to eat as children had lower BMIs as adults. The more a mother was concerned about her daughter's weight as a child, and the more she restricted fatty food intake, the less the woman was satisfied with her current body image. Disordered eating of adult women was positively related to their mothers' restriction of their fatty food intake as children, and negatively related to the mothers' monitoring of their food intake as children. Combining the samples and subdividing them into four BMI intervals showed that the obese women were higher on all but one of the recalled maternal child feeding practices, as well as on disordered eating and body dissatisfaction. Age was found to be positively related to BMI and drive for thinness, but not to body dissatisfaction or disordered eating, with older women having higher BMI and more drive for thinness. Study 3 sampled adult men from the community and found that recalled maternal child feeding practices predicted adult BMI and disordered eating for men, as well as for women. Considerable sex differences were found for all study variables. Recollection of maternal child feeding practices may have a formative role in the development of body image, disordered eating, and BMI for men and women, even into adulthood.     

The Efficacy of a Group Triple P (Positive Parenting Program) for Chinese Parents with a Child Diagnosed with ADHD in Hong Kong: A Pilot Randomised Controlled Study

The present pilot study evaluated the efficacy of the Level 4 Group Positive Parenting Program (Triple P) with Hong Kong Chinese parents who had a child with attention deficit/hyperactivity disorder (ADHD), using a randomised controlled trial design. It was a mixed research method involving quantitative measurement and semi‐structured focus group. Participants were randomly assigned to Triple P (n = 8) or control group (n = 9) and completed measures on child disruptive behaviours, sense of parenting efficacy and satisfaction, family stress and service needs. Outcomes were assessed at pre‐, post‐, and 3‐month follow‐up. A focus group was also conducted with the participants in the intervention group upon the programme completion. Compared with the control group, the intervention group reported a significant reduction in intensity of child behaviour problems and a significant increase in parenting efficacy at post‐intervention. The gain in reducing intensity of child disruptive behaviours maintained to 3 months after the completion of programme. Qualitative data suggested the three key elements to help both parents and children get positive changes: understanding and empathy, emotional control, and persistence in applying positive parenting strategies. The results partially provided preliminary evidence supporting the efficacy of Triple P in reducing child behaviour problems for ADHD in Chinese society.     

A Strengths-Based Longitudinal Career Intervention for Junior Secondary School Students with Special Educational Needs: a Mixed-method Evaluation

The mixed-method study reported here was designed to evaluate a strengths-based career intervention program for secondary school students with mild special educational needs (SEN). A sample of 32 SEN students (19 boys: 13 girls) from 5 inclusive schools in Hong Kong were recruited to a treatment group. An additional 32 SEN students (19 boys: 13 girls) were selected to form the control group matched for age, gender and parents’ education level. The special needs exhibited by both groups were in areas of literacy and numeracy, attention deficits, and social-emotional problems, but did not include severe or complex disabilities. Participants in both groups responded to pre- and post-intervention questionnaires covering career development self-efficacy, personal and social development self-efficacy, and meaning in life. As a follow-up, two teachers and three social workers providing support to SEN students, and the 32 participants were interviewed several months after the intervention. Interviews also took place with teachers, social workers and students to evaluate the perceived effects of the intervention. Findings indicated significant interactions between Time 1 and Time 2, and between groups (control vs. treatment) in personal goal-setting, career goal-setting, and the presence of meaning in life. Additionally, several themes were identified from the interviews suggesting that the intervention did have positive effects on SEN students’ career, personal and social development self-efficacy, and acquisition of meaning in life.
