Food deprivation and conditioned flavor preferences based on sweetened and unsweetened foods

In four experiments, rats’ preferences for flavors consumed under high deprivation versus low deprivation were measured. In Experiment 1, rats preferred flavors received in unsweetened food under high deprivation to flavors received in unsweetened food under low deprivation. This preference did not vary with amount of food used to deliver the flavors (1-g vs. 16-g wet mash). Sweetening the food (0.10% saccharin) eliminated this preference when 16 g of mash was received, but not when 1 g of mash was received (Experiments 2 and 3). Sweetening the mash even more (0.15% saccharin) eliminated the preference when 1 g of mash was received, as well as when 20 g of mash was received. We suggested that the reinforcing value of sweetness is reduced by increasing deprivation level.     

False Uniqueness: the Self‐Perception of New Entrants to Higher Education in the UK and Its Implications for Access – a Pilot Study1

A central tenet of contemporary education policy relates to the desire to extend higher education (HE) provision to less advantaged groups (‘widening participation’). Our paper contends that a key behavioural obstacle to widening participation lies in the erroneous belief that persists among potential entrants from disadvantaged backgrounds as to their capabilities of succeeding within the HE environment – a perception that serves to deflate application/recruitment rates from such groupings. We test this ‘false uniqueness’ thesis using a sample of 127 new UK undergraduates, finding that students drawn from lower social class backgrounds consistently underestimated their abilities vis‐à‐vis the overall cohort.     

Benefits of omega‐3 supplementation for schoolchildren: Review of the current evidence

Despite the potential impact nutrition may have on learning, there have been surprisingly few papers published directed towards the educational research community. In contrast, omega‐3 supplementation studies are being frequently cited in the media, leading to parents asking for advice and guidance. The purpose of this article is to review the evidence to date for any effect of using omega‐3 supplementation in school‐aged children. This article focuses on the research that has been undertaken, particularly in relation to behaviour, education and cognitive development, in both typically developing populations as well as in children with specific learning difficulties and developmental disorders. Recommendations for future studies in this area have been highlighted in view of current knowledge. In conclusion, it was found that there is a shortage of properly controlled omega‐3 supplementation trials, particularly with typically developing children, to advocate the supplementation of all children with omega‐3 fatty acids, but due to the known importance of omega‐3 fatty acids in the brain and early development, further research is required.     

Research Fictions: Arts-Informed Narratives That Disrupt the Authority of the Text

In this paper I examine the dilemma faced by reflexive narrative inquirers who write in the first-person “I” while advocating for a postmodern reading of the “self.” This paper asks the question: How can the reflexive educational researcher craft a research narrative that, on the one hand, strives for self-presence, while on the other hand, denies the transparency of language? I discuss current post-structuralist critiques of educational research rhetoric, and extend the critique to narrative research, suggesting that an arts-informed approach to narrative allows researchers to disrupt the authority of their text. I explore the use of a specific fictionalizing technique – the unreliable narrator – to assist readers in critically deciphering reflexive research narratives.
