The perils of double consciousness: The role of thought suppression in stereotype threat

The goal of the present research is to demonstrate, and then alleviate, the role of thought suppression in depressing women’s math performance under stereotype threat. We hypothesize that when taking a math test, women (but not men) attempt to suppress thoughts of the math-related gender stereotype. Suppression leads to underperformance when it uses up cognitive resources. In Study 1, women underperform on a math test and show postsuppressional rebound of the stereotype when cognitive resources are reduced. In Study 2, women suppress the stereotype after a math test begins, but show rebound when the test is complete. In Study 3, making the stereotype irrelevant to the test improves performance and reduces postsuppressional rebound. In Studies 4 and 5, we test a strategy women can use to make suppression easier, and show that it restores math performance. Theoretical and practical implications are discussed.     

A Qualitative Investigation of Women's and Men's Body Image Concerns and Their Attitudes Toward Aging

In-depth interviews were conducted with 42 women and men (aged 22–62 years) to explore their relationships with their bodies. The particular focus was age-related changes in body image and attitudes toward the body aging, an area that has received little research attention to date. Thematic analysis revealed distinctive gender differences. Men commonly conceptualized their bodies as a holistic entity, whereas women commonly had compartmentalized conceptualizations. They also construed the importance of their bodies differently: men tended to focus on functionality, and women tended to focus on display. These findings may help to explain gendered consequences of body dissatisfaction. Accounts about the aging of the body support a “double standard of aging.” Women viewed aging most negatively in terms of its impact on appearance, whereas men reported a neutral or even positive impact on appearance.     

The influence of teacher expectations on student achievement in physical education classes: Pygmalion revisited

The main purpose of this study was to explore the relation between teacher expectations and student achievement in physical education classes, in the light of three complementary hypotheses. Student achievement may confirm teacher expectations because these expectations create self‐fulfilling prophecies, create perceptual biases, or accurately predict, without influencing, student achievement (Jussim, 1989 ). Another purpose was to examine the mediating role played by students' perceived ability in the teacher expectancy process. Study data were obtained from 173 students and 7 teachers. Path analysis revealed that teacher expectations have weak self‐fulfilling effects, strongly predicted student achievement mainly because they are accurate, and have no biasing effects on teacher judgements. Results also show evidence concerning the role of partial mediator of perceived student ability in the confirmation process of teacher expectations. Copyright © 2002 John Wiley & Sons, Ltd.     

The behavioural treatment of sleep difficulties in children with an intellectual disability

Reinforcement, instruction giving, partner support strategies, bedtime routine, and standard extinction were taught to the parents of three boys (aged 5–10 years) with an intellectual disability and sleeping difficulties. Sleep was measured using sleep diaries and actigraphy, and daytime behaviour was monitored using diaries and direct observation. At referral, all children needed a parent present to fall asleep, two had co‐sleeping difficulties, and two had night waking difficulties. At post‐intervention, all children were falling asleep independently, co‐sleeping was eliminated for two children, and night waking was reduced in one child. An extinction burst was experienced by two children, with one family putting their child back to bed 259 times on the first night. Though one child still had night waking difficulties following intervention, actigraph recording demonstrated an improvement in his sleep quality. In addition to the children's independence, improvements were seen for sleep length, sleep latency, and morning wake time. However, improvements in daytime behaviour showed inconsistency across behaviours and settings. Improvement in sleep was maintained at a three month follow‐up. It was concluded that using extinction to address sleep problems in children with an intellectual disability is effective and approved of by parents, but any impact on daytime behaviour is equivocal.

Atypical development of language and social communication in toddlers with Williams syndrome

Williams syndrome (WS) is a genetic disorder which results in an uneven cognitive profile. Despite superior language compared to other syndromes in the phenotypic outcome, toddlers with WS are as delayed in their language onset and early linguistic development as are toddlers with other syndromes. The cause of this delay in WS is as yet unknown. In a series of experiments, we examined whether atypical socio‐interactive precursors to language could contribute to the explanation of the late language onset and atypical developmental pathways observed in WS. Experiment 1 showed that despite superficially good social skills, toddlers with WS were only proficient at dyadic interaction. They were impaired in triadic interaction, essential for the referential uses of language, and showed none of the correlations between socio‐interactive markers and language seen in the typical controls. Experiment 2 focused on the comprehension and production of referential pointing. Again, the WS group was impaired, despite vocabulary levels higher than those of typically developing controls. Finally, Experiment 3 examined fine motor skills. The WS lack of pointing could not be explained in terms of motor impairments, since the WS toddlers were proficient at fine motor control, such as the pincer grip. Overall, our data indicate that the early stages of WS language follow an atypical pathway. The findings challenge the frequent claims in the literature that individuals with Williams syndrome have preserved linguistic and social skills.     

Phonological similarity and lexicality effects in children's verbal short-term memory: concerns about the interpretation of probed recall data

Probed recall tasks are often used to assess aspects of children's verbal short-term memory development because they are not subject to potentially confounding output effects. However, the marked recency effects that are observed in probed recall means that these tasks are potentially insensitive to experimental manipulations when later serial positions are probed. This clouds the interpretation of data from probed recall studies in which children of different ages are presented with to-be-remembered lists of different lengths. In two experiments we examined the magnitude of phonological similarity and lexicality effects in both 5- to 6- and 8- to 9-year-old children. In each case performance on probed recall tasks was contrasted with that seen on tests of serial recognition. The results indicated that probed recall tasks are potentially less sensitive to experimental manipulations in younger than older children. However, comparable effects of both phonological similarity and lexicality were seen in both age groups using serial recognition procedures. These findings have implications for the interpretation of other studies that have examined the development of verbal short-term memory using probed recall and for theoretical accounts of the development of phonological similarity and lexicality effects in children.     

The explicit learning of new names for known objects is improved by dexamphetamine

A randomised, double-blind, placebo-controlled, between subjects study design (N=37) was used to investigate the effects of dexamphetamine on explicit new name learning. Participants ingested 10mg of dexamphetamine or placebo daily over 5 consecutive mornings before learning new names for 50 familiar objects plus fillers. The dexamphetamine group recognised and recalled the new names more accurately than the placebo group over the 5 days and 1 month later. Word learning success was not associated with baseline neuropsychological performance, mood, cardiovascular arousal, or sustained attention. These results may have implications for the pharmacological treatment of acquired naming difficulties.     

Inattention/Overactivity Following Early Severe Institutional Deprivation: Presentation and Associations in Early Adolescence

The current study examined the persistence and phenotypic presentation of inattention/overactivity (I/O) into early adolescence, in a sample of institution reared (IR) children adopted from Romania before the age of 43 months. Total sample comprised 144 IR and 21 non-IR Romanian adoptees, and a comparison group of 52 within-UK adoptees, assessed at ages 6 and 11 years. I/O was rated using Rutter Scales completed by parents and teachers. I/O continued to be strongly associated with institutional deprivation, with continuities between ages 6 and 11 outcomes. There were higher rates of deprivation-related I/O in boys than girls, and I/O was strongly associated with conduct problems, disinhibited attachment and executive function but not IQ more generally, independently of gender. Deprivation-related I/O shares many common features with ADHD, despite its different etiology and putative developmental mechanisms. I/O is a persistent domain of impairment following early institutional deprivation of 6 months or more, suggesting there may be a possible pathway to impairment through some form of neuro-developmental programming during critical periods of early development.     

Do Theory of Mind and Executive Function Deficits Underlie the Adverse Outcomes Associated with Profound Early Deprivation?: Findings from the English and Romanian Adoptees Study

Theory of Mind (ToM) and Executive Function (EF) have been associated with autism and with attention-deficit hyperactivity disorder (ADHD), and hence might play a role in similar syndromes found following profound early institutional deprivation. In order to examine this possibility the current study included a group of 165 Romanian adoptees, of whom 144 were adopted into the UK from deprived institutional settings before 43months of age, and a group of 52 within-UK adoptees, all adopted before 6months of age. Both groups were assessed at 6 and 11years. The Strange Stories task was used to assess ToM and the Stroop task was used to assess EF, both at age 11. The Romanian adoptees displayed deficits in both ToM and EF compared with the within-UK adoptee group. The degree of deficit was greater for children who had experienced more than 6months of institutional deprivation. Deficits in both domains (ToM and EF) were associated with each of the three apparently deprivation-specific problems, namely quasi-autism, disinhibited attachment and inattention/overactivity. Statistical analyses indicated a mediating role for both ToM and EF with respect to quasi-autism; possibly a partial mediating role for EF with respect to inattention/overactivity; and probably no mediating role for either ToM or EF in the case of disinhibited attachment. In conclusion, there is evidence for a possible mediating role for ToM and EF in the development of some apparently deprivation-specific difficulties in institution-reared Romanian adoptees, but neither accounts for the overall pattern of deprivation-related difficulties.     

"With a little help from my friends...": the role of co-witness relationship in susceptibility to misinformation

Inaccuracies in eyewitness accounts can occur when witnesses are exposed to post-event misinformation via discussion with a co-witness. The current study examined the role of co-witness relationship by comparing the memory performance of pairs of romantic couples, friends and previously unacquainted strangers with that of individuals. Ninety-six participants viewed an event and then discussed the witnessed event with a stranger, a romantic partner or a friend. One member of each pair saw a theft take place during the witnessed event. Individual group participants did not discuss the witnessed event with anyone. Results indicate that all co-witness dyads produced less accurate recall accounts than participants who did not interact with another witness. However, witnesses who were previously acquainted with their co-witness (either in a friendship or romantic relationship) were significantly more likely to report information obtained from their co-witness that they had not seen themselves. Prior acquaintance also led to an increased number of incorrect attributions of both guilt and innocence.
