Touch communicates distinct emotions

The study of emotional signaling has focused almost exclusively on the face and voice. In 2 studies, the authors investigated whether people can identify emotions from the experience of being touched by a stranger on the arm (without seeing the touch). In the 3rd study, they investigated whether observers can identify emotions from watching someone being touched on the arm. Two kinds of evidence suggest that humans can communicate numerous emotions with touch. First, participants in the United States (Study 1) and Spain (Study 2) could decode anger, fear, disgust, love, gratitude, and sympathy via touch at much-better-than-chance levels. Second, fine-grained coding documented specific touch behaviors associated with different emotions. In Study 3, the authors provide evidence that participants can accurately decode distinct emotions by merely watching others communicate via touch. The findings are discussed in terms of their contributions to affective science and the evolution of altruism and cooperation.     

A cross-cultural investigation of cognitions and depressive symptoms in adolescents

Adolescents (N=2,272) from Hong Kong and the United States provided information regarding their depressive symptoms, cognitions (self-efficacy, negative cognitive errors, and hopelessness), and stressful events between 2 surveys 6 months apart. Depressive symptoms and hopelessness were higher, and self-efficacy and negative cognitive errors were lower in Hong Kong than in the United States. Cognitions were associated with concurrent depressive symptoms and predicted depressive symptoms 6 months later in both cultures. The "reverse" model was also supported with more variance predicted by depressive symptoms to later cognitions than from cognitions to depressive symptoms. There was some support for the hypothesis that self-efficacy is less salient in collective compared with individualistic cultures. These findings extend cognitive theories of depression to a non-Western culture.     

Physical activity and psychological well-being in advanced age: a meta-analysis of intervention studies

A meta-analysis examined data from 36 studies linking physical activity to well-being in older adults without clinical disorders. The weighted mean-change effect size for treatment groups (d(C). = 0.24) was almost 3 times the mean for control groups (d(C). = 0.09). Aerobic training was most beneficial (d(C). = 0.29), and moderate intensity activity was the most beneficial activity level (d(C). = 0.34). Longer exercise duration was less beneficial for several types of well-being, though findings are inconclusive. Physical activity had the strongest effects on self-efficacy (d(C).= 0.38), and improvements in cardiovascular status, strength, and functional capacity were linked to well-being improvement overall. Social-cognitive theory is used to explain the effect of physical activity on well-being.     

Suicide in the 1970s: A Second Look

ABSTRACT: The decade of the 70's has been reviewed with the document Suicide Prevention in the 70's serving as a guide. Twenty-one goals put forward in the report were reviewed in light of subsequent progress in the field. Although progress was noted on many fronts, four areas were outstanding in the sense that envisioned goals were met or exceeded. These involved the areas of promulgation of information about suicide, establishment of standards and certification procedures, development of regional organizations to forward training and program development, and education of the public to improve awareness of suicide as a public problem. This analysis also identified areas where little or no progress has been made. From this there developed four recommendations:

• 1 The funding and establishment of a national case file using a standard nomenclature and a standard data base to improve epidemiologic knowledge, and to provide pooled data appropriate for more sophisticated research analyses.
• 2 The establishment of a task force to study the application of program evaluation methods to suicide prevention efforts.
• 3 The development of new programs at local levels to try to reach known high-risk groups and to provide relevant programs of suicide prevention for them.
• 4 Making creative efforts toward elaboration of a comprehensive theory of life-threatening behavior and exploration of developmental correlates of such behavior.

     

Child and parent predictors of perceptions of parent--child relationship quality

OBJECTIVE/METHOD: Predictors of perceptions of parent-child relationship quality were examined for 175 children with ADHD, 119 comparison children, and parents of these children, drawn from the follow-up phase of the Multimodal Treatment Study of Children with ADHD. RESULTS/CONCLUSION: Children with ADHD perceived their mothers and fathers as more power assertive than comparison children. Children higher on depressive symptomatology also perceived their mothers and fathers as less warm and more power assertive. Mothers perceived themselves as more power assertive and fathers perceived themselves as less warm if they were higher on depressive symptomatology themselves or had children with ADHD or higher levels of depressive symptomatology. Several interactions indicated that the association between child factors and parental perceptions of warmth and power assertion often depended on parental depressive symptomatology. The findings resolve a previous contradiction in the literature regarding the relationship between child depressive symptoms and parental perceptions of parent-child relationship quality.     

Does a Positive Bias Relate to Social Behavior in Children With ADHD?

This study examines whether positively biased self-perceptions relate to social behaviors in children with attention-deficit/hyperactivity disorder (ADHD) as compared to control children. The social behaviors of children with ADHD (n = 87) were examined relative to control children (CTL; n = 38) during a laboratory-based dyadic social interaction task. Children with ADHD were subgrouped into those with a positive illusory bias (PIB) in their self-perceptions (ADHD + PIB) versus those without such a bias (ADHD – PIB). Using a behavioral coding system adapted for this study, ADHD + PIB, ADHD – PIB, and CTL participants were compared on objectively coded social behaviors occurring within the context of the social interaction task. Whereas both ADHD groups displayed more disruptive behavior than controls, only the ADHD + PIB group displayed less prosocial behavior and less effortful behavior. This study breaks new ground by examining positively biased self-perceptions as they relate to social behavior in children with ADHD and provides promising new insight into the social problems experienced by these children.     

Depression is associated with the escalation of adolescents' dysphoric behavior during interactions with parents

Though much is known about the stable mood patterns that characterize depressive disorder, less attention has been directed to identifying and understanding the temporal dynamics of emotions. In the present study, we examined how depression affects the trajectory of dysphoric and angry adolescent emotional behavior during adolescent-parent interactions. Adolescents (72 depressed; 69 nondepressed) engaged in video recorded positive and negative interactions with their parents. Depressed adolescents showed a linear increase in dysphoric behaviors throughout the negative interactions, while the incidence of these behaviors remained relatively stable across the interactions among nondepressed adolescents. A similar linear increase was not found in angry behavior. These findings show that depression in adolescence is associated with greater escalation of dysphoria during conflictual interactions between adolescents and their parents.

Developmental trends in auditory processing can provide early predictions of language acquisition in young infants

Auditory processing capabilities at the subcortical level have been hypothesized to impact an individual's development of both language and reading abilities. The present study examined whether auditory processing capabilities relate to language development in healthy 9‐month‐old infants. Participants were 71 infants (31 boys and 40 girls) with both Auditory Brainstem Response (ABR) and language assessments. At 6 weeks and/or 9 months of age, the infants underwent ABR testing using both a standard hearing screening protocol with 30 dB clicks and a second protocol using click pairs separated by 8, 16, and 64‐ms intervals presented at 80 dB. We evaluated the effects of interval duration on ABR latency and amplitude elicited by the second click. At 9 months, language development was assessed via parent report on the Chinese Communicative Development Inventory ‐ Putonghua version (CCDI‐P). Wave V latency z‐scores of the 64‐ms condition at 6 weeks showed strong direct relationships with Wave V latency in the same condition at 9 months. More importantly, shorter Wave V latencies at 9 months showed strong relationships with the CCDI‐P composite consisting of phrases understood, gestures, and words produced. Likewise, infants who had greater decreases in Wave V latencies from 6 weeks to 9 months had higher CCDI‐P composite scores. Females had higher language development scores and shorter Wave V latencies at both ages than males. Interestingly, when the ABR Wave V latencies at both ages were taken into account, the direct effects of gender on language disappeared. In conclusion, these results support the importance of low‐level auditory processing capabilities for early language acquisition in a population of typically developing young infants. Moreover, the auditory brainstem response in this paradigm shows promise as an electrophysiological marker to predict individual differences in language development in young children.
