Processes linking weight status and self-concept among girls from ages 5 to 7 years

This study assessed the relationship between girls' weight status and self-concept and examined peer teasing and parent criticism as potential mediators of this relationship. Data were collected for 182 girls and their parents when the girls were 5 and 7 years old. At each age, girls' body mass index, self-concept, peer weight-related teasing (child report), and parents' criticism of girls' weight status (spouse report) were assessed. At ages 5 and 7, girls who were more overweight reported lower self-concept. Peer teasing and parent criticism mediated the relationship between weight status and self-concept at age 7, but not at age 5. In addition, the duration and timing of parent criticism across ages 5 and 7 mediated the association between girls' weight status at age 5 and perceived peer acceptance at age 7.     

Multiple object tracking in people with Williams syndrome and in normally developing children

Multiple object tracking is hypothesized to utilize visual indexes, which may provide rapid, parallel access to a limited number of visual objects, thereby supporting a variety of spatial tasks. We examined whether faulty indexing might play a role in the severe visuospatial deficits found in Williams syndrome. We asked observers to track from one to four targets in a display of eight identical objects. Objects remained stationary (static condition) or moved randomly and independently (moving condition) for 6 s, after which observers pointed to the objects they thought were targets. People with Williams syndrome were impaired in the moving condition, but not the static condition, compared with mental-age-matched control participants. Normal children who were younger than the mental-age-matched control children did not show the same profile as individuals with Williams syndrome, which suggests that the difference between the tasks in Williams syndrome did not reflect simple developmental immaturity. Error analysis revealed that all groups had "slippery" indexes, falsely identifying target neighbors, and further suggested that people with Williams syndrome deploy fewer indexes than do people without this disorder.     

Intra-individual variability in task performance after cognitive training is associated with long-term outcomes in children

The potential benefits and mechanistic effects of working memory training (WMT) in children are the subject of much research and debate. We show that after five weeks of school-based, adaptive WMT 6–9 year-old primary school children had greater activity in prefrontal and striatal brain regions, higher task accuracy, and reduced intra-individual variability in response times compared to controls. Using a sequential sampling decision model, we demonstrate that this reduction in intra-individual variability can be explained by changes to the evidence accumulation rates and thresholds. Critically, intra-individual variability is useful in quantifying the immediate impact of cognitive training interventions, being a better predictor of academic skills and well-being 6–12 months after the end of training than task accuracy. Taken together, our results suggest that attention control is the initial mechanism that leads to the long-run benefits from adaptive WMT. Selective and sustained attention abilities may serve as a scaffold for subsequent changes in higher cognitive processes, academic skills, and general well-being. Furthermore, these results highlight that the selection of outcome measures and the timing of the assessments play a crucial role in detecting training efficacy. Thus, evaluating intra-individual variability, during or directly after training could allow for the early tailoring of training interventions in terms of duration or content to maximise their impact.     

A Treasure Hidden in a Field: Katherine Sonderegger on Scripture

This paper considers Katherine Sonderegger's view of Scripture. In volume 2 of her Systematic Theology Sonderegger suggests a ‘dogmatic reading’ that overcomes the impasse of both a too historicist and a too theologically narrow view of the biblical text. As evidenced in her innovative reading of Isaiah 53, Sonderegger's engagement with Scripture is both thoroughly traditional and a novel approach to theologically engaging the biblical text.     

Predictors of preschool language environments and their relations to children's vocabulary

Despite support for the importance of early language environments, little is known about the naturally occurring experiences children have in preschool settings. The current study sample included 91 children (M_age = 4.72 years; 56% male; 67% White) from 23 preschool classrooms and nearly 1500 h of language environment data from three waves throughout the preschool year. Of the sociodemographic characteristics, family income is most closely related to children's preschool language environments. A standard deviation increase in family income was related to children hearing approximately one million more adult words in their preschool classroom. However, conversational turns were the more robust predictor of vocabulary skills with effect sizes around 0.20, depending on model specification. Theoretical and policy implications of these findings are discussed.     

The abstraction of form in semantic categories

Undergraduates were asked to generate a name for a hypothetical new exemplar of a category. They produced names that had the same numbers of syllables, the same endings, and the same types of word stems as existing exemplars of that category. In addition, novel exemplars, each consisting of a nonsense syllable root and a prototypical ending, were accurately assigned to categories. The data demonstrate the abstraction and use of surface properties of words.

‘We Like You, But We Don’t Want You’—The Impact of Pregnancy in the Workplace

This study considered whether pregnant women are considered as mothers (to be) in the workplace. Working from the stereotype content model (SCM) we predicted that pregnant women would be stereotyped as warm and incompetent, and experience workplace discrimination; with these effects accentuated in masculine-type occupations. Eighty-two Australian University undergraduates evaluated a candidate who was pregnant or not for a masculine- or feminine-type short-term position. Results provided mixed support for the SCM. Across both occupations, the pregnant candidate was rated as warmer, more competent, but was discriminated against in comparison to the non-pregnant candidate. We suggest that participants may employ a shifting standard of comparison, thus highlighting a potential limitation of the usefulness of traditional SCM measures with individual targets.     

“Shopping While Black”: Examining Racial Discrimination in a Retail Setting1

To investigate racial discrimination in the marketplace, we conducted a field experiment to examine both overt and subtle forms of retail discrimination. “Customers” browsing in high‐end retail stores asked a salesperson if they would remove a security sensor from a pair of sunglasses prior to trying them on in front of a mirror. Although the request to remove the sensor was granted in all conditions, the salespersons showed greater levels of suspicion (i.e., staring, following) in the Black conditions, especially in the male‐group condition. These findings are consistent with current field research examining subtle biases toward other stigmatized groups.
