Functional neuroanatomy of gesture–speech integration in children varies with individual differences in gesture processing

Gesture is an integral part of children's communicative repertoire. However, little is known about the neurobiology of speech and gesture integration in the developing brain. We investigated how 8‐ to 10‐year‐old children processed gesture that was essential to understanding a set of narratives. We asked whether the functional neuroanatomy of gesture–speech integration varies as a function of (1) the content of speech, and/or (2) individual differences in how gesture is processed. When gestures provided missing information not present in the speech (i.e., disambiguating gesture; e.g., “pet” + flapping palms = bird), the presence of gesture led to increased activity in inferior frontal gyri, the right middle temporal gyrus, and the left superior temporal gyrus, compared to when gesture provided redundant information (i.e., reinforcing gesture; e.g., “bird” + flapping palms = bird). This pattern of activation was found only in children who were able to successfully integrate gesture and speech behaviorally, as indicated by their performance on post‐test story comprehension questions. Children who did not glean meaning from gesture did not show differential activation across the two conditions. Our results suggest that the brain activation pattern for gesture–speech integration in children overlaps with—but is broader than—the pattern in adults performing the same task. Overall, our results provide a possible neurobiological mechanism that could underlie children's increasing ability to integrate gesture and speech over childhood, and account for individual differences in that integration.     

Witnessing racial discrimination shapes collective action for racial justice: Enhancing awareness of privilege among advantaged groups

Three studies tested whether witnessing incidents of racial discrimination targeting Black people may motivate White people to engage in collective action for racial justice. In studies of White Americans (Study 1) and self-identified White activist “allies” (Study 2), witnessing incidents of racial discrimination predicted greater willingness to participate in collective action for racial justice, through the pathway of enhanced awareness of racial privilege. Studies 1 and 2 showed that awareness of racial privilege uniquely predicted the link between witnessing incidents of racial discrimination and willingness to participate in collective action for racial justice; these effects were consistent both with and without controlling for Whites’ sense of identification with their own racial group. Study 3 tested experimentally how witnessing incidents of racial discrimination may compel White people to become more motivated to engage in collective action for racial justice. Compared to those in a control condition, White participants who were randomly assigned to watch a brief video depicting recent discriminatory incidents targeting Black people (e.g., Starbucks incident in Philadelphia, housing incident at Yale University) tended to show greater motivation to engage in collective action for racial justice, an effect accounted for largely by enhanced awareness of racial privilege. How witnessing incidents of racial discrimination can transform views of privilege and willingness to stand up for racial justice among members of advantaged racial groups is discussed.     

You are not alone – adolescents’ experiences of participation in a structured skills training group for ADHD

Little is known about how adolescents with attention deficit/hyperactivity disorder (ADHD) experience participating in group therapy, an important factor to consider when developing treatment methods for this age group. This study aimed to explore how adolescents with ADHD experience participating in a structured skills training group program based on dialectical behavioral therapy. Semi-structured interviews were conducted with 20 adolescents (15–18 years of age) with ADHD after participating in a structured skills training group. The interviews were transcribed verbatim and qualitative content analysis were used to analyze the text. The participants emphasized the value of meeting other adolescents with ADHD and the opportunity to exchange experiences, strategies and tips. Participating in the group treatment made the adolescents realize that they were not alone, and feelings of togetherness and an increased acceptance of themselves were described. The participants associated the treatment with elevated knowledge and understanding, for example, about ADHD, their own functioning and helpful strategies. They also described emotional and behavioral changes, such as higher self-esteem, fewer inter-personal conflicts and improved concentration. Activating and experiential exercises were considered important elements of the treatment, and the participants expressed a need for a variation of exercises, as well as more time for practicing skills, discussions and breaks. The results indicate that the group format add an extra value to the treatment and that the use of an active approach throughout the treatment is of importance for this group of patients.     

Parent–child gender interaction in the relation between retrospective self-reports on parental love and current self-esteem

A retrospective questionnaire study investigated the relation between current self-esteem in adult men ( n =34) and women ( n =99) and self-reported experience of parental "unconditional positive regard" during childhood. For both men and women the perception of the father's unconditional regard was significantly related to self-esteem. For women only a weak relation was found between the reported experience of maternal regard and self-esteem in adulthood; a comparison of younger and older women showed that this relation was weaker for younger women. The results were interpreted in terms of a greater ambivalence in women towards the mother, possibly as a result of women's more complex separation and identification processes; the difference between younger and older women could indicate that this ambivalence decreases over the years. The implications of this interpretation for the validity of retrospective accounts is discussed, suggesting that the validity could increase over the years.     

Measuring depression for Swedish nonclinical adolescents: Factorial validity and equivalence of the Beck Depression Inventory across gender

Building upon earlier confirmatory factor analytic research that validated a 2nd-order 4-factor structure of the Beck Depression Inventory for Canadian and Swedish nonclinical adolescents, the purposes of the present study were twofold: (a) to test the factorial structure of the Swedish version of the instrument separately for males ( n = 559) and females ( n = 537), and (b) to test for its measurement and structural equivalence across gender. Except for three minor discrepancies involving correlated errors, the hypothesized model best described the data for both males and females. Nonetheless, the imposition of equality constraints across sex revealed differences bearing on the measurement of six items, and latent construct relations involving the Somatic Elements factor. Four gender differences in factorial structure replicated findings for Canadian adolescents. Results have important implications for researchers, clinicians, and others whose interests focus on nonclinical adolescent depression.     

Subitizing and counting processes in young children

Children attending the first grade in school were instructed to tell the number of dots (1–9) presented on a screen. The response latencies were related to the number of dots by two different linear relations for each subject. The first of these had a slope of about 0.1 sec/dot, was applicable for the encoding of 1–3 dots, and was taken as an indication of a subitizing process. The second linear relation was applicable for 5–9 dots and had a slope of about 1.0 sec/dot reflecting the speed of a counting process. The average intersection between the functions was located at 3.22 dots. The results were compared with earlier investigations of adult subjects who on the average subitize 6 dots and count 1 dot in about 0.4 sec. It was subitizing process being higher for adults. If the encoding of a stimulus has not been terminated within about 1.5 sec for children and adults the stimulus has instead to be identified in either a counting or an estimating process.     

Schizophrenic reactions in the Serial Spiral After-Effect Test

A group of 52 schizophrenics, 13 neurotics and 30 normals were studied by means of the Serial Spiral After-Effect Test. Schizophrenics with classical overt symptoms showed significantly higher values compared to neurotics, normals and latent schizophrenics on the residual variability in ten consecutive durations of the after-effect, i.e. the total variability minus the variability ascribable to linear change. Significant correlations were obtained between residnal variability in the Serial Spiral After-Effect Test and psychosis, as assessed by a psychiatric rating scale for the schizophrenics with classical overt symptoms, when the mean level in the Serial Spiral After-Effect Test was checked.
