How long does it last? The persistence of the effects of ostracism in the socially anxious

Previous research has demonstrated that ostracism (to be excluded and ignored) leads to detrimental effects on four human needs (belonging, control, self-esteem, and meaningful existence; Williams, 2001). These detrimental effects, however, may be more pronounced, or more prolonged, in particular individuals (see Williams & Zadro, 2001). In the present study, we examined the persistence of the detrimental effects of ostracism in high and low socially anxious participants. The results show that being ostracized affected both groups at the immediate test, and that the high socially anxious participants recovered their primary needs more slowly. The results also show that being ostracized affects personality/attractiveness ratings of sources of ostracism, and increases the likelihood of interpreting ambiguous situations in a threatening manner. Overall, the study illustrates that a comprehensive understanding of ostracism, and the effects of moderating factors such as social anxiety, requires assessing the effects across time rather than only focusing on immediate reactions.     

Automatic Activation and Use of Gender Subgroups

Two experiments tested whether, similarly to global gender categories, gender subgroups are activated and applied on an automatic basis. In Experiment 1 (N?=?90) the female subgroup career woman was activated in a subliminal priming procedure. Experiment 2 (N?=?40) contrasted the subliminal priming of career woman with the activation of the global category woman. In both experiments the activated subgroup was applied to a target person in an ostensibly unrelated judgment task: Judgments of the target person were significantly higher on features typical for the subgroup than on untypical features. Activating the global category led to clearly different judgments than when the subgroup was activated. Results are discussed with respect to the use of global and subordinate gender categories in social categorization.     

Are Emotions Natural Kinds?

ABSTRACT— Laypeople and scientists alike believe that they know anger, or sadness, or fear, when they see it. These emotions and a few others are presumed to have specific causal mechanisms in the brain and properties that are observable (on the face, in the voice, in the body, or in experience)—that is, they are assumed to be natural kinds. If a given emotion is a natural kind and can be identified objectively, then it is possible to make discoveries about that emotion. Indeed, the scientific study of emotion is founded on this assumption. In this article, I review the accumulating empirical evidence that is inconsistent with the view that there are kinds of emotion with boundaries that are carved in nature. I then consider what moving beyond a natural-kind view might mean for the scientific understanding of emotion.     

Processing speed in children treated for brain tumors: effects of radiation therapy and age

The current study examined processing speed in children two years post-treatment for brain tumors (BT) with radiation therapy (RT) compared to those treated with without RT. Participants included 59 children (4–17 years) with BT assessed as part of the Brain Radiation Investigative Study Consortium (BRISC). Processing speed was assessed at two time points: Time1 (3–9 months post-surgery) for 26 children who received whole brain or focal RT (RT group) and 33 treated without RT (no-RT group), and again two years later (Time2) for 42 participants (17 RT, 25 no-RT). Linear mixed effects (LME) regression analyses examined differences in cognitive and motor speed between groups and across visits, with age at Time1 (age1) treated as a moderating variable, and sex and primary tumor size as covariates. No effects for treatment group or visit were found for motor speed (Pegboard) or mean reaction time (Attention Network Task). On the Wechsler Processing Speed Index (PSI), the no-RT group performed better than the RT group, with a group-by-age interaction such that across visits, the difference between the no-RT and RT groups was larger among children who were older at initial treatment (≥10 years) than among those who were younger (<10 years). Cumulative brain injury earlier in life (tumor, surgery, plus RT) may result in greater impact on more complex tasks of cognitive efficiency. Children receiving RT showed reduced processing speed over time, with a larger group difference among those who were over 10 years at treatment.     

Diaphragmatic breathing as treatment for escape‐maintained aggression

Coping skills, such as diaphragmatic breathing, are commonly recommended to help individuals work through challenging situations. We evaluated diaphragmatic breathing as treatment for aggression of three individuals diagnosed with autism spectrum disorder or Angelman syndrome. Functional analysis results demonstrated that each participant engaged in aggression maintained by social‐negative reinforcement. Diaphragmatic breathing treatment without extinction was conducted in a work context and involved prompting diaphragmatic breathing contingent on precursors to aggression; treatment was effective in reducing the rate of aggression for one of three participants. For the two other participants, other reinforcement‐based interventions (differential reinforcement of other behavior or functional communication training with extinction) were necessary to decrease aggression.     

Reengagement With Education: A Multidisciplinary Home-School-Clinic Approach Developed in Australia for School-Refusing Youth

School refusal (SR) can result in decreased academic achievement, impaired social connections, and family stress. Current interventions for SR include behavioral and cognitive-behavioral treatments that are not always effective. Incorporating multidisciplinary work that includes therapeutic and educational interventions may enhance outcomes for youth displaying SR. The In2School program fosters a working partnership between mental health clinicians and teachers. It was designed to meet the needs of young people missing more than 50% of school in the previous 6 weeks due to mental health disorders, including anxiety or depression. This paper reports on an action research study in which the In2School program was piloted. Over a 14-week period, therapeutic and educational interventions were integrated into the learning environment via a transitional classroom to support youths’ return to school. Outcomes of this program are reported for the first cohort of 7 youth. Of these youth, 6 returned to mainstream schooling with attendance levels being maintained for 6 months after completing the intervention. Progress was observed in mental health recovery, quality of life reports, increased social interactions with peers, and positive experiences at school. The preliminary results presented in this paper suggest that a multidisciplinary, home-school-clinic intervention holds promise for helping school-refusing youth to return to school.     

Altered lateralization of dorsal language tracts in 6‐week‐old infants at risk for autism

Altered structural connectivity has been identified as a possible biomarker of autism spectrum disorder (ASD) risk in the developing brain. Core features of ASD include impaired social communication and early language delay. Thus, examining white matter tracts associated with language may lend further insight into early signs of ASD risk and the mechanisms that underlie language impairments associated with the disorder. Evidence of altered structural connectivity has previously been detected in 6‐month‐old infants at high familial risk for developing ASD. However, as language processing begins in utero, differences in structural connectivity between language regions may be present in the early infant brain shortly after birth. Here we investigated key white matter pathways of the dorsal language network in 6‐week‐old infants at high (HR) and low (LR) risk for ASD to identify atypicalities in structural connectivity that may predict altered developmental trajectories prior to overt language delays and the onset of ASD symptomatology. Compared to HR infants, LR infants showed higher fractional anisotropy (FA) in the left superior longitudinal fasciculus (SLF); in contrast, in the right SLF, HR infants showed higher FA than LR infants. Additionally, HR infants showed more rightward lateralization of the SLF. Across both groups, measures of FA and lateralization of these pathways at 6 weeks of age were related to later language development at 18 months of age as well as ASD symptomatology at 36 months of age. These findings indicate that early differences in the structure of language pathways may provide an early predictor of future language development and ASD risk.     

Offline consolidation supersedes prior knowledge benefits in children's (but not adults’) word learning

Prior linguistic knowledge is proposed to support the acquisition and consolidation of new words. Adults typically have larger vocabularies to support word learning than children, but the developing brain shows enhanced neural processes that are associated with offline memory consolidation. This study investigated contributions of prior knowledge to initial word acquisition and consolidation at different points in development, by teaching children and adults novel words (e.g., ballow) that varied in the number of English word‐form “neighbours” (e.g., wallow, bellow). Memory for the novel word‐forms was tested immediately after training, the next day and 1 week later, to assess the time‐course of prior knowledge contributions. Children aged 7–9 years (Experiments 1, 3) and adults (Experiment 2) recalled words with neighbours better than words without neighbours when tested immediately after training. However, a period of offline consolidation improved overall recall and reduced the influence of word‐form neighbours on longer term memory. These offline consolidation benefits were larger in children than adults, supporting theories that children have a greater propensity for consolidating phonologically distinctive language information. Local knowledge of just a single word‐form neighbour was enough to enhance learning, and this led to the individual differences in word recall that were related to adults’ global vocabulary ability. The results support the proposal that the relative contributions of different learning mechanisms change across the lifespan, and highlight the importance of testing theoretical models of word learning in the context of development.
