Overshadowing of situational cues with variable but not fixed intertrial intervals

In two experiments, we examined the conditions under which signaling an unconditioned stimulus (US) with a nominal conditioned stimulus (CS) interferes with the conditioning of situational cues in defensive freezing in the rat. Subjects received footshock USs that were (1) either signaled or unsignaled and (2) either varied or fixed in their temporal location within the conditioning session. Experiment 1, with only one trial per session, yielded no evidence that signaling affected pretrial freezing using either a fixed or variable interval between placement in the context and shock onset. In a test in which no CSs or footshocks were presented, groups that previously had received footshock at a fixed temporal location showed greatest freezing at around that same time. For groups that had received footshocks at various times, freezing declined across the test session. Experiment 2 showed overshadowing of pretrial freezing after more extensive conditioning with many trials per session, but only if the intershock intervals were variable rather than fixed.     

Chemistry concepts and group cognitive structure: A study of undergraduate nursing students

The long term aim of this study is to document changes in the nature and level of conceptual understanding revealed by a cohort of undergraduate nursing students. The outcome of such a study may be used in future review and redesign processes by curriculum planners. Conceptual understanding of physiology and pharmacology, areas which are central to nursing studies depends, in turn, on an understanding of certain chemical concepts. This paper describes the group cognitive structure of 60 first year preservice nursing students, with respect to 21 basic chemistry concepts. Group cognitive structure is represented by non-metric multidimensional scaling of data obtained from individual concept maps prepared by students. The impact of prior studies in chemistry on the level of understanding revealed is discussed. Specializations: Cognition and science education, behavioural ecology and ethology.     

Exploring the context of strengths – a new approach to strength-based assessment

Since the 1990s many strength-based assessments (for example, inventories, checklists, interview schedules) have been developed for use with children and young people, but these have offered a limited appraisal of the contexts in which strengths are present. In this study a new form of contextualised strength-based assessment was used within the routine practice of an educational psychologist. A multiple case study explored how this approach worked with eight children and young people referred to a local authority educational psychology team, ranging in age from 6.9 to 19.2 years. Qualitative data were analysed holistically using a story-board method. In all cases, participants identified situations or contexts which they associated with the presence of specific strengths. In some cases they highlighted aspects of a situation which might be hypothesised to have pedagogical value. There is discussion of the tensions that can arise in using this approach in schools when a more negative view of a pupil has already emerged. Nevertheless, the introduction of fresh information, about the type of contexts which suited specific children and young people, was helpful in providing ideas and recommendations which may have otherwise been missed.     

Mothers’ Goals Influence Their Responses to Children’s Performance: An Experimental Study in the United States and Hong Kong

This research examined the role of mothers’ self-worth and self-improvement goals in their responses to children’s performance in the United States (80% European American) and Hong Kong (100% Chinese). Mothers (N = 330) were induced to prioritize self-worth or self-improvement among children (M_age = 10.24 years; 48% girls) . Mothers induced to prioritize self-worth (vs. self-improvement) used more success-oriented responses in both regions (ds = 0.53 and 0.35). Mothers induced to prioritize self-improvement (vs. self-worth) used more failure-oriented responses only in the United States (d = 0.29). Mothers’ success-oriented responses predicted more positive beliefs and affect in a cognitive task among children (βs = .10–.18). Taken together, the findings support the importance of parents’ goals in the socialization process.     

Word reading and reading comprehension: stability, overlap and independence

Longitudinal twin data were analyzed to investigate the etiology of the stability of genetic and environmental influences on word reading and reading comprehension, as well as the stability of those influences on their relationship. Participating twin pairs were initially tested at a mean age of 10.3 years, and retested approximately five years later. Both word reading and comprehension were found to be highly stable, and genetic influences were primarily responsible for that stability. In contrast to studies with younger participants, no unique genetic influences were observed at follow-up testing in this older sample. High genetic correlations were obtained between word reading and reading comprehension at both ages, indicating common genetic influences. However, significant genetic influence on comprehension was also observed, independent of that on word reading. Although the phenotypic relation between the two measures appeared to decline across time, the genetic etiology of this relation was highly stable.     

Foreign Language Study in Elementary Schools: Benefits and Implications for Achievement in Reading and Math

Educators and policy makers in many countries have been expressing concern about how to improve students’ achievement in reading and math. This article explores and proposes a solution: introduce or increase foreign language study in the elementary schools. Research has shown that foreign language study in the early elementary years improves cognitive abilities, positively influences achievement in other disciplines, and results in higher achievement test scores in reading and math. Successful foreign language programs for elementary schools include immersion, FLES, and FLEX programs.

A Toe in the Water: Introducing Exhibitions on Video with Young People at the Whitechapel Art Gallery

This paper focuses on the production of introductory videos for gallery exhibitions through collaborations between young people, professional artists and gallery staff. Fundamental to this process is the quality of encounter young people involved have with original works of art, artists and gallery staff. Their enquiries about the work on show and critical response is valued by the gallery and its diverse audiences for its unique and individual perspective. Students are invited to explore and familiarise themselves with the work prior to articulating their ideas and views on video within the exhibition spaces. Recorded footage is then edited to a professional standard and shown in the gallery during the run of each show. The videos are also posted out to local schools, marketed as peer‐led introductions to each exhibition, in order to offer up questions and ideas to students and teachers prior to their gallery visit. A commissioned, external evaluation of the videos, against their stated aims and objectives, was undertaken by Goldsmiths College's Art in Education team.
