Conditioning with taste as the CS in conditioned flavor preference learning

There appear to be unconditioned affective reactions to the four basic tastes: liking for sweet and salt and disliking for sour and bitter. We attempted to modify these reactions by pairing the tastes with calories and with sweeter tastes. Differing sucrose concentrations were ineffective in reversing the preference for salt over citric acid or for saccharin over quinine. We could, however, reverse the preference for salt over citric acid, producing an actual preference for sour over salt, by using sucrose and saccharin as the reinforcers. The initial reactions to tastes could also be modified by reducing the initial difference in affect produced by the tastes through mixing both tastes with sucrose.     

“I Could Not Believe That Would Happen”: Challenges and Opportunities in a Critical,Project-Based Clinical Experience

As part of a youth summer program—a partnership between a large Southeastern university and the local school district—middle-school-aged youth, preservice teachers, and doctoral candidates interested in arts-based literacy practices spent their mornings in June 2016 engaging in activities that both explored and expanded thinking around their communities, schools, and families. Whereas the youth were enrolled in a monthlong creative arts and tentative unschooling experiment that ran roughly the length of a typical school day, university faculty and graduate students were engaged in a course on the application of youth participatory action research (YPAR). This article is an examination of the experience of preservice teachers, through an analysis of their reflections on events within the course, to suggest ways forward through the promises and perils of project-based, clinical preservice teaching experiences. In our exploration of the experiences of focal preservice teachers when engaged with youth coresearchers in a monthlong YPAR project, we found the work to have been filled with contradictions, unexpected shifts, and moments of great understanding, community affiliation, and suffering.     

Revisiting print exposure: exploring differential links to vocabulary,comprehension and reading rate

Undergraduates (N=171) completed a revised version of the Author Recognition Test ( Stanovich & West, 1989 ). The resulting print exposure scores were divided into two dimensions: personal reading experience (primary print knowledge – PPK) and secondary print knowledge (SPK). Both PPK and SPK were correlated with print exposure, but not with each other. PPK correlated more strongly with reading‐related variables (vocabulary, comprehension and reading rate) than did SPK. Of particular importance, PPK accounted for variance in all three criterion variables after the effects of SPK had been factored out. Thus, these data support the notion that it is the act of reading over and above memory for reading‐related information that furthers the development of linguistic skill.     

Young children's combinatoric strategies

Children aged between 4 years 6 months and 9 years 10 months were individually administered a series of novel tasks involving the formation of different combinations of two items, selected from discrete sets of items. An analysis of the children's performance revealed a series of six, increasingly sophisticated, solution strategies ranging from a random selection of items through to a systematic pattern in item choice (cf. Piaget and Inhelder's, 1975, combinatoric operations). A significant number of children independently adopted more efficient solution procedures as they progressed on the tasks, with many displaying an algorithmic procedure reflecting the odometer strategy (holding one item constant while systematically varying each of the other items). Given that children as young as 7 years demonstrated this systematic strategy, it would appear that, within the appropriate learning environment, young children can discover a procedure for forming n x n combinations prior to the stage of formal operations postulated by Piaget and Inhelder. The findings support the inclusion of the combinatorial domain as a topic of investigation in the elementary school curriculum.     

Globalisation and science education: the case of Sustainability by the Bay

It is impossible to consider contemporary science education in isolation from globalisation as the dominant logic, rethinking and reconfiguring social and cultural life in which it is located. Carter (J Res Sci Teach 42, 561–580, 2005) calls for a close reading of policy documents, curriculum projects, research studies and a range of other science education texts using key concepts from globalisation theory to elucidate the ways in which globalisation shapes and is expressed within science education. In this paper, we consider an example from our own practice of a school-based curriculum project, Sustainable Living by the Bay, as one such instance. The first section reviews neoliberalism and neoconservativism necessary to understand how globalisation penetrates education, while the second outlines aspects of the curriculum project itself. As there were many different facets to the development and implementation of a project like Sustainable Living by the Bay, there is space only to elaborate two examples of the globalisation discourse. The first example concerns the government policy initiative that funded the project while the second example focuses on learner- centred pedagogies as globalisation’s pedagogies of choice.     

What is literacy for students with severe learning difficulties? Exploring conventional and inclusive literacy

This paper arises from research into inclusive literacy for pupils with severe learning difficulties who do not learn to read and write conventionally. The ultimate aim of the study was to seek out examples of good practice in teaching and learning literacy that includes students with severe learning difficulties and disseminate them as widely as possible. Thirty-five schools were visited and observations made in 122 lessons. Sixty-one teachers were interviewed and their paperwork examined. Ten focus groups and five 'expert witnesses' were consulted, alongside desk-based research designed to locate 'good practice'. Teachers used a mixture of conventional (e.g., texts) and non-conventional (e.g., pictures, film and oral) media, although more observations were made of conventional literacy teaching (e.g., phonic work) than of non-conventional (e.g., filmmaking). Results from the research suggest that few students with severe learning difficulties are likely to learn to read and write conventionally (i.e., read for pleasure, work and study) and teachers may be relying too much on teaching traditional literacy to them. It may be useful to explore teaching and learning around alternative media such as still and moving images, live theatre and storytelling, digital technology and the arts. Although some teachers are making good use of these media, the potential of these media for providing inclusive literacy experiences could be further developed.     

Deciding How to Deceive: Differences in Communication and Detection Between Good and Bad Liars

To study deception, participants were randomly assigned the role of allocator or recipient in an ultimatum negotiation game. Allocators “earned” 7 dollars and divided the money between themselves and recipient and communicated the decision either face-to-face or through text chat. Recipients were unaware the amount the allocator had, and therefore, allocators could deceive. Most allocators used deception. We hypothesized that participants who self-identified as good liars would communicate more face-to-face than through text chat when deceiving, and this was supported for deceptive omission but not fabrications. Good liars were more likely to have their truths correctly detected than bad liars.
