Socially transmitted food preferences can be used to study long-term memory in rats

Immediately after a recently fed rodentdemonstrator interacts with a conspecificobserver, the observer shows a substantially enhanced preference for whatever food its demonstrator ate. Here we show that (1) influence of a single, 30-min interaction with a demonstrator on an observer’s food preference lasts for at least 1 month, and (2) observers interacting on 2 successive days with a demonstrator fed a different diet on each day show significantly enhanced preferences for both diets a month later. Such enduring effects of single, brief interactions between a demonstrator rat and its observer provide an efficient means for studying physiological and behavioral substrates of long-term memory in rodents. Together with the results of previous studies of social influences on food choices of rats, the present results also suggest that rats may use information acquired from conspecifics to identify both toxic and safe foods for many weeks after they have acquired this information.     

Sending Minnie the Minx Home: Comics and reading choices

This paper reports on aspects of two qualitative studies which focused on children's interests in comics. The earlier study (Millard, 1997) was part of a larger survey of 254 boys' and girls' reading interests, sampled at the point of transition between primary and secondary school. The second study, which forms the main body of this paper, explores the reactions to a home-school comic lending library based in three primary classrooms over a period of seven weeks. Results from both studies are discussed in this paper and the implications for the development of the primary school literacy curriculum explored.     

Family and social risk,and parental investments during the early childhood years as predictors of low-income children's school readiness outcomes

Using data from the National Early Head Start (EHS) Research and Evaluation Project (N = 1851), the current study examined relations among cumulative family and social risk, assessed during infancy and the preschool years, and children's prekindergarten achievement, self-regulatory skills, and problematic social behavior, testing if these associations were mediated through two sets of family processes–responsive parenting practices and the provision of language stimulation and literacy practices. Structural equation modeling results highlight the significance of the timing of children's experience of risk in predicting school readiness competencies. Risk exposure during infancy was observed to be most detrimental for children's school readiness skills and was partially mediated by risk exposure during the preschool years and family processes, assessed during toddlerhood and the preschool years. Moderation analyses revealed no difference in the strength of relationships among the study variables by EHS assignment or by race/ethnicity.     

A Systematic Review of Barriers and Facilitators of Disability Disclosure and Accommodations for Youth in Post-Secondary Education

This review critically appraised the literature on disability disclosure and accommodations for youth with disabilities in post-secondary education (PSE). Systematic searches of 8 databases identified 36 studies meeting our inclusion criteria. These studies were analysed with respect to the characteristics of the participants, methodology, results of the studies and quality of evidence. Five thousand, one hundred and seventy four participants (mean age 26.4) were represented across six countries. Barriers to disability disclosure and requests for accommodations in PSE included stigma, discrimination, lack of knowledge of supports and how to access them, type of course and instructor, coping styles, and nature of the disability. Facilitators included supports and resources, coping and self-advocacy skills, mentorship, and realising the benefits of disclosure. Factors affecting the process and timing of disability disclosure in PSE included the type of disability, and mode of disclosure. There was a lack of consensus on the timing of disclosure.     

Students' Perceptions of Teacher Support Across the Transition from Primary to Secondary School

This study examines the degree to which students' perceptions of teacher support are related to school type (primary versus secondary). The sample included 7,205 students from years 5 to 7 in primary school and years 8 to 10 in secondary school. Previous research has concluded that perceptions of school change negatively when students move from primary to secondary school. However, this research has been criticized for not accounting for age‐related changes in students' perception of school. Results from this study show a linear downwards tendency for perceived teacher support, with no obvious abrupt change between primary and secondary school. Our findings do not, therefore, support the idea that the transition from primary to secondary school affects students' perception of teacher support in a negative way.
