How young children judge whether a word is one they know: a dual criterion account

Word familiarity judgment may be important for word learning, yet little is known about how children make this judgment. We hypothesized that preschool-age children differ in the judgment criteria that they use and that this difference derives from individual differences in basic memory processes. Those who have superior phonological working memory, but who retrieve less semantic information than their peers, base the judgment on whether they recognize a word’s sound form. Those who show the opposite memory profile base the judgment on whether they retrieve a word’s meaning. The results of two studies of 3- and 4-year-olds were consistent with these claims. Among those performing poorly on one memory measure, judgment accuracy was directly related to performance on the other memory measure. These memory-judgment relations were also found to be highly specific. This is the first investigation to demonstrate the usefulness of an individual differences approach for identifying relations between linguistic judgment processes and basic memory processes during early childhood.

Exercise and Depression: A Review of Reviews

There has been considerable research interest in the effects of exercise upon depression outcomes. Recently, health agencies in the United Kingdom (UK) and beyond have made several guidance statements on this issue. Therefore, this review seeks to provide a synthesis of evidence regarding the effectiveness of exercise in the management of depression (including postnatal depression) in adults. Studies were identified by searching PubMed, Medline, Cochrane Library (CENTRAL) and PsychINFO using relevant search terms. The article describes how meta-analyses from peer reviewed journals have reported exercise as treatment for depression is more effective than no treatment, as effective as traditional interventions in some instances, possibly a promising approach to postnatal depression and has equivalent adherence rates to medication. However, reviews have also raised concerns about the methodological quality of trials, possible overestimation of treatment effects and lack of data regarding long term benefits. Based on the available evidence it is concluded that while awaiting further high quality trial evidence it would seem appropriate for exercise to be recommended in combination with other treatments.     

Normality and impairment following profound early institutional deprivation: a longitudinal follow-up into early adolescence

Longitudinal analyses on normal versus impaired functioning across 7 domains were conducted in children who had experienced profound institutional deprivation up to the age of 42 months and were adopted from Romania into U.K. families. Comparisons were made with noninstitutionalized children adopted from Romania and with nondeprived within-U.K. adoptees placed before the age of 6 months. Specifically, the validity of the assessment, the degree of continuity and change in levels of functioning from 6 to 11 years, and the factors in the pre- and postadoption environment accounting for heterogeneity in outcome were examined. Pervasive impairment was significantly raised in children experiencing institutional deprivation for > or =6 months of life, with a minority within this group showing no impairment. There was no additional significant effect of duration of deprivation beyond the 6-month cutoff, and few other predictors explained outcome. The pattern of normality/impairment was mainly established by 6 years of age, with considerable continuity at the individual level between 6 and 11 years. The findings are discussed in terms of the possibility of a sensitive period for development.     

Movement abnormalities and the progression of prodromal symptomatology in adolescents at risk for psychotic disorders

The link between movement abnormalities and psychotic disorders is presumed to reflect common neural mechanisms that influence both motor functions and vulnerability to psychosis. The prodromal period leading to psychotic disorders represents both a viable point for intervention and a developmental period that, if studied, could shed light on etiology; however, no published studies have examined the temporal progression of this link. A group with high levels of prodromal symptomatology (i.e., adolescents with schizotypal personality disorder [SPD]; n = 42) and both psychiatric controls (with other personality disorders or conduct disorder [OD]; n = 30) and nonpsychiatric controls ([NC]; n = 49) were recruited. Videotapes of structured psychiatric interviews were coded for movement abnormalities by raters blind to participants' diagnostic status, and follow-up assessments were conducted 1 year later. Controlling for psychotropic medications, the authors found that adolescents with SPD exhibited significantly more motor abnormalities in the face and upper body than did OD and NC controls. At baseline, movement abnormalities were positively correlated with the severity of positive, negative, and total prodromal symptoms. Within the SPD group, baseline movement abnormalities predicted symptom severity 1 year later. Movement abnormalities represent an early risk indicator that may be predictive of later symptom severity and potentially of psychosis onset.     

Effects of information about group members on young children's attitudes towards the in‐group and out‐group

Research shows that being a member of a group is sufficient to instigate more positive attitudes towards the in‐group than an out‐group in young children. The present study assessed whether children's intergroup attitudes during the middle childhood years are moderated by additional information about in‐group and out‐group members, as proposed by Aboud's (1988) socio‐cognitive theory (ST). To a minimal group 6‐, 8‐, and 10‐year‐old children (N=159) were assigned, and received information, or no information, about the interests and activities of the in‐group and out‐group members. Results indicated that the in‐group was always rated more positively than the out‐group, and that the in‐group's ratings were unaffected by either the in‐group or out‐group information. In contrast, out‐group ratings were affected by out‐group information, but only when there was no information available about the in‐group. The implications of the findings for ST, and for social identity development theory, are discussed.

Differences in body esteem by weight status,gender, and physical activity among young elementary school-aged children

Body satisfaction is important for the prevention of disordered eating and body image disturbances. Yet, little is known about body esteem and what influences it among younger children. The purpose of this study was to evaluate body esteem and the relationships between body esteem, weight, gender, and physical activity in elementary school children. A total of 214 third graders in a U.S. Midwestern state participated in this correlational study. The Body Mass Index-for-age, the Body Esteem Scale (BES), BE-Weight, BE-Appearance, and a Physical Activity Checklist were used to examine the relationships between the variables using bivariate correlations and analysis of variance. While children's body esteem did not differ by physical activity, important interactions were identified between weight status and gender in global body esteem and BE-Appearance. It is critical to examine attitudes about weight and appearance and the relationship between body esteem and self-esteem further among middle childhood-aged children.
