“Sleeper effects” in development: Fact or artifact?

The evolution of the concept of “sleeper effects” is traced from the work of J. Kagan and H. A. Moss (Birth to Maturity. New York: Wiley, 1962) to the present time. The phenomenon was originally inferred, without cross-validation, in the domain of personality, from correlations with early events which were stronger late in development than earlier. More recently it has been extended to account for long-term attainment differences associated with the presence or absence of preschool intervention. It seems possible that the original evidence may have capitalized upon chance fluctuations of few among many correlations. What is more certain, however, is that as currently used the term is imprecise, usually unjustified, and irrelevant to the supposed later effects of brief early intervention.     

Tailoring Cognitive Behavioral Treatment for Binge Eating in Adolescent Girls

Whereas effective treatments exist for adults with recurrent binge eating, developmental factors specific to adolescents point to the need for a modified treatment approach for youth. We adapted an existing cognitive behavioral therapy treatment manual for adults with bulimia nervosa and binge eating disorder (Fairburn, 2008) for use with adolescents. This paper presents a number of clinical case vignettes, drawn directly from interactions with teen participants, that illustrate some of the developmental factors common to adolescents—as well as the importance of our adaptations to address for these factors.     

Strategy Shifts and Expertise in Solving Transformation Rule Problems

The acquisition of expertise in formal problem solving has been assumed to involve either a shift from backwards to forwards inference, or a shift from unguided to guided forwards inference. In a longitudinal study, the acquisition of formal problem-solving expertise was investigated. Participants were tested as novices before undertaking controlled practice in the problem domain which involved transformation rule problems, and were finally tested as experts. The direction of inference in problem solutions was found to be inadequate to describe the strategic differences between novices and experts. Therefore, a new solution coding system was applied, based on atomic components of problem solution. Analysis of novice and expert solutions revealed no systematic strategy in the novice stage—solutions were confused and contained unproductive steps and backtracking. Several strategies were found in the expert solutions, but they did not agree with previously reported results. It was therefore proposed that the acquisition of expertise does not involve a change from one specific solution strategy to another, but rather the development of an efficient strategy, which can differ between participants.     

Identifying barriers to help-seeking: a qualitative analysis of students' preparedness to seek help from tutors

A qualitative study based on the first-hand accounts of students in higher education was conducted Participants were encouraged to explain, in their own terms, their own help-seeking behaviour. The focus for their explanations was 'help-seeking from academic staff'. The aim of the study was to construct a culturally sensitive account of barriers to help-seeking in a student population. The discussion focuses on how studies of this kind might complement and extend what is already known about help-seeking m the extant literature.
