The impact of continuing care adherence on environmental risks, substance use, and substance-related problems following adolescent residential treatment.

The effectiveness of adolescent treatment to reduce substance use has been demonstrated by a number of different literature reviews, yet longer term outcome studies have suggested that continued alcohol and other drug use is common. Participation in continuing care services and reductions in environmental risk factors (e.g., peer substance use or alcohol or drug use in the home) have both been found to be associated with improved posttreatment substance use. The authors conducted Path analysis to examine the experimental direct effect of the Assertive Continuing Care Protocol (S. H. Godley, M. D. Godley, & M. L. Dennis, 2001) on general continuing care adherence following residential treatment and the protocol's indirect effect (via general continuing care adherence) on social and environmental risk factors, as well as subsequent substance use and substance-related problems. Supporting previous findings, the final model indicates that greater adherence to continuing care is associated with reductions in environmental risk, which in turn is associated with reduced adolescent substance use and substance-related problems 9 months after discharge from residential treatment.     

A year of unprecedented progress in Down syndrome basic research

The years 2006 and 2007 saw the publication of three new and different approaches to prevention or amelioration of Down syndrome effects on the brain and cognition. We describe the animal model systems that were critical to this progress, review these independent breakthrough studies, and discuss the implications for therapeutic approaches suggested by each.     

Preschool Children's Emotional Expressions with Peers: The Roles of Gender and Emotion Socialization

This study examined whether mothers and fathers reported using different emotion socialization strategies and whether these differences were related to preschoolers' gender and emotional expressiveness during peer play. Ninety percent of the children were Caucasian, 6% were Asian-American, and 4% were Mexican-American. The positive expressive behavior of 82 preschoolers participating in two conflict eliciting situations with two same gender peers were coded. The scores for the two sessions were averaged. All of the mothers and 63 of the fathers were administered three emotion socialization questionnaires. Results revealed that girls expressed more positive emotion than boys. In addition, mothers and fathers also reported using different emotion socialization practices and, in some cases, this was dependent upon their child's gender. The findings also showed that mothers' and fathers' reports of emotion socialization practices were differentially related to children's emotionally expressive behavior during peer play. In addition, fathers' emotion socialization practices accounted for unique variance in children's emotionally expressive behavior over and above that explained by the maternal emotion socialization variables. These findings highlight the importance of mothers' and fathers' emotion socialization practices for preschoolers' emotional competence in emotionally challenging situations with peers.     

On the adaptive function of children's and adults’ false memories

Recent research has shown that memory illusions can successfully prime both children's and adults' performance on complex, insight-based problems (compound remote associates tasks or CRATs). The current research aimed to clarify the locus of these priming effects. Like before, Deese–Roediger–McDermott (DRM) lists were selected to prime subsequent CRATs such that the critical lures were also the solution words to a subset of the CRATs participants attempted to solve. Unique to the present research, recognition memory tests were used and participants were either primed during the list study phase, during the memory test phase, or both. Across two experiments, primed problems were solved more frequently and significantly faster than unprimed problems. Moreover, when participants were primed during the list study phase, subsequent solution times and rates were considerably superior to those produced by those participants who were simply primed at test. Together, these are the first results to show that false-memory priming during encoding facilitates problem-solving in both children and adults.     

Parents’ Verbal Communication and Childhood Anxiety: A Systematic Review

Parents’ verbal communication to their child, particularly the expression of fear-relevant information (e.g., attributions of threat to the environment), is considered to play a key role in children’s fears and anxiety. This review considers the extent to which parental verbal communication is associated with child anxiety by examining research that has employed objective observational methods. Using a systematic search strategy, we identified 15 studies that addressed this question. These studies provided some evidence that particular fear-relevant features of parental verbal communication are associated with child anxiety under certain conditions. However, the scope for drawing reliable, general conclusions was limited by extensive methodological variation between studies, particularly in terms of the features of parental verbal communication examined and the context in which communication took place, how child anxiety was measured, and inconsistent consideration of factors that may moderate the verbal communication–child anxiety relationship. We discuss ways in which future research can contribute to this developing evidence base and reduce further methodological inconsistency so as to inform interventions for children with anxiety problems.     

Preterm infants' affective responses in independent versus toy-centered play with their mothers

The affective behavior of medically high-risk (HR) and low-risk (LR) infants, along with a control group of full-terms (FT), was compared at 6 months of age during a 5-minute independent and a 5-minute toy-centered play session with their mothers. Because previous research has shown that joint toy play places a burden on the attentional capacities of HR infants, it was predicted that they would show less positive affect and more negative affect in toy-centered (vs. independent) play and joint attention (vs. face-to-face) interactions than would the LR or FT infants. Results showed that the HR infants displayed fewer smiles across the independent and mother toy-centered play condition and across face-to-face and joint attention interactions than LR or FT infants. The findings also indicated that the mother's presence facilitated the expression of positive affect for all three infant groups.     

Filtering and condensation tasks with integral and separable dimensions

Speed of classification was measured with a filtering task (only one dimension relevant) and a condensation task (two dimensions relevant) with integral dimensions of Munsell value and chroma and separable dimensions of value and size. The filtering task was easier with separable than with integral dimensions, but the condensation task was easier with integral than with separable dimensions. The results emphasize the importance of dimensional structure with separable dimensions and similarity or distance structure with integral dimensions.
