The structure and correlates of self-reported symptoms in 11-year-old children

Self-reports of DSM-III symptomatology were obtained from 792 11-year-old children using the Diagnostic Interview Schedule for Children (DISC). We report results concerning 13 subscales derived from the DISC. Factor-analysis of the subscales suggested a broad distinction between externalizing and internalizing disorder for boys' self-report. For girls, two separate internalizing factors representing anxiety and depression emerged. We also found sex differences in correlates of self-reported disorder. Finally, we examined agreement between child and parent and teacher reports. Overall, agreement was relatively low, although somewhat higher for child-parent than for child-teacher.The Dunedin Multidisciplinary Health and Development Research Unit is supported by the Medical Research Council of New Zealand and the Departments of Education and Health, and involves several departments of the University of Otago. Much of the data are gathered by voluntary workers from the Dunedin community. The authors are indebted to the many people whose contributions make this ongoing study possible.

Histamine reverses a memory deficit induced in rats by early postnatal maternal deprivation

Early partial maternal deprivation causes long-lasting neurochemical, behavioral and brain structural effects. In rats, it causes a deficit in memory consolidation visible in adult life. Some of these deficits can be reversed by donepezil and galantamine, which suggests that they may result from an impairment of brain cholinergic transmission. One such deficit, representative of all others, is an impairment of memory consolidation, clearly observable in a one-trial inhibitory avoidance task. Recent data suggest a role of brain histaminergic systems in the regulation of behavior, particularly inhibitory avoidance learning. Here we investigate whether histamine itself, its analog SKF-91844, or various receptor-selective histamine agonists and antagonists given into the CA1 region of the hippocampus immediately post-training can affect retention of one-trial inhibitory avoidance in rats submitted to early postnatal maternal deprivation. We found that histamine, SKF-91844 and the H2 receptor agonist, dimaprit enhance consolidation on their own and reverse the consolidation deficit induced by maternal deprivation. The enhancing effect of histamine was blocked by the H2 receptor antagonist, ranitidine, but not by the H1 receptor antagonist pyrilamine or by the H3 antagonist thioperamide given into CA1 at doses known to have other behavioral actions, without altering locomotor and exploratory activity or the anxiety state of the animals. The present results suggest that the memory deficit induced by early postnatal maternal deprivation in rats may in part be due to an impairment of histamine mediated mechanisms in the CA1 region of the rat hippocampus.     

The Emotion Regulation Strategies of Adolescents and their Parents: An Experience Sampling Study

Parents are the main socialization agents in the development of emotion regulation (ER). In this study, we evaluated adolescents’ and their respective parents’ perspectives about their use of two ER strategies (cognitive reappraisal and expressive suppression) in daily life. In addition, we evaluated the within-family associations between adolescents’ and their parents’ use of strategies. We controlled for adolescents’ gender and age and the perceived quality of their relationships with their parents (mothers and fathers). The sample consisted of 33 12- to 18-year-old adolescent–father–mother triads, totaling 99 participants. Parents and adolescents reported their use of ER strategies in response to eight random prompts throughout the day, by means of the experience sampling method for 1 week. Participants provided 4082 reports on their momentary experiences. The data were analyzed using multilevel modeling to account for the hierarchical structure of the repeated daily assessments. The significant association between parents’ and adolescents’ use of ER strategies was specific to mother–adolescent dyads. The significant association between adolescents’ and their mothers’ ER strategies varied as a function of the adolescents’ age and the quality of their relationship with their mothers according to adolescents’ reports, but not as a function of adolescent gender. These findings suggest that mothers have a role in their adolescents’ emotion regulation in a developmental period characterized by autonomy from parental guidance.     

Mood and fluency: The case of pronunciation ease,liking and trust

We explored the impact of mood on the judgemental consequences of word pronounceability in six Experiments (1 preregistered, total N = 1183). Positive and negative mood was induced via video clips (all but Experiment 4) and subliminal affective primes (Experiment 4). Additionally, participants were presented with easy- and difficult-to-pronounce letter strings. These were framed as target words to be judged for liking (Experiments 1–2), as names of eBay sellers to be judged for trustworthiness (Experiments 3–5), or as either seller names or passwords to provoke opposing interpretations of pronunciation fluency (Experiment 6). While pronounceability showed a robust effect across experiments, mood did not modulate the judgemental use of (Experiments 1–4), the correction for (Experiment 5) and the interpretation (Experiment 6) of word pronounceability. In conclusion, the judgemental effects of pronounceability persist despite the presence of more objective and task-pertinent cues, resist judgemental correction and remain unaffected by affective states.
