Role of exteroceptive background context in taste-aversion conditioning and extinction

In two experiments, saccharin (CS) and lithium chloride (US) were paired in a context consisting of specific visual, auditory, tactual, and olfactory cues. The saccharin aversion was then extinguished in a context free from conditioning-context cues. Later, saccharin preference tests were given in the presence and absence of these cues. The results indicated that the background cues of the conditioning trial controlled the amount of saccharin drunk on extinction trials, and, furthermore, that extinction of the taste aversion was context specific; i.e., groups given extinction trials in a different (from conditioning) context retained their saccharin aversion in the conditioning context only. The results indicate an important role played by the exteroceptive context in taste-aversion conditioning.     

Active Learning session based on Didactical Engineering framework for conceptual change in students’ equilibrium and stability understanding

ABSTRACT

Engineering students on control courses lack a deep understanding of equilibrium and stability that are crucial concepts in this discipline. Several studies have shown that students find it difficult to understand simple familiar or academic static equilibrium cases as well as dynamic ones from mechanics even if they know the discipline’s criteria and formulae. Our aim is to study the impact of a specific and innovative classroom session, containing well-chosen situations that address students’ misconceptions. We propose an example of Active Learning experiment based both on the Didactical Engineering methodology and the Conceptual Fields Theory that aims at promoting a conceptual change in students. The chosen methodology allows, at the same time, a proper design of the student learning activities, an accurate monitoring of the students’ rational use during the tasks and provides an internal tool for the evaluation of the session’s efficiency. Although the expected starting conceptual change was detected, it would require another activity in order to be reinforced.     

Grades degrade group coordination: deteriorated interactions and performance in a cooperative motor task

At school, pupils often cooperate on common projects and must coordinate their different individual actions. However, grades are pervasively used even in cooperative situations, which make the pupils’ differences in achievement and their relative rank salient and may reduce their inclination to work constructively with others. Thus, we hypothesized that grades would elicit disruptive interactions and reduce performance in a cooperative cognitive-motor task necessitating inter-individual coordination of members. In a study with 5th graders, grades (vs. a neutral concept) were primed at the onset of a cooperative group interaction. Results showed that, although pupils were set to work cooperatively, priming grades (vs. neutral concepts) harmed inter-individual coordination by eliciting more negative dominant behaviours among pupils during interactions, which decreased group performance.     

The complexity of trauma response: a 4-year follow-up of adolescent Cambodian refugees

OBJECTIVE: The objective of this study was to document the psychosocial adjustment of young refugees during their adolescence and its association with the war-related trauma experienced by their family before migration. METHOD: Data were collected on 57 young Khmer resettled in Montreal and followed from early to late adolescence. The associations between premigratory exposure to political violence and postmigratory mental health and social adjustment were estimated for early, mid-, and late adolescence. RESULTS: The associations between premigratory exposure to political violence and postmigratory psychosocial adjustment fluctuated over the adolescence period. Overall, the adolescents whose families were more highly exposed to political violence tended to report a more positive social adjustment and less mental health symptoms than those less exposed. CONCLUSION: The high expectations of Cambodian parents towards their children and the preservation of traditional values despite the Khmer rouge attempts to eradicate them might contribute to explain the paradoxical association between the families' exposure to political violence and the adolescents' psychosocial adjustment in the host country. Although children and adult refugees seen in clinical setting are reminders of the negative effects of adversity, resilience should be more systematically explored in community samples to further our understanding of the long-term effects of trauma.     

Understanding of the alphabetic principle through invented spelling among hearing‐impaired children learning to read and write: experimentation with a pedagogical approach

Given the problems experienced by hearing‐impaired individuals in learning the written language, a pedagogical approach was tested. The study examined the links between the development of representations of alphabetic system and the results in reading and writing of first graders. In the study, there were 31 hearing‐impaired children and 25 hearing ones. Invented spelling was measured three times during the school year. Reading and writing tests were given at the end of the year. The results obtained revealed a similarity between the learning profile of the hearing‐impaired children and that of the hearing children. It also demonstrated the importance of the work done through invented spelling, among the hearing‐impaired children. Thus, like their hearing peers, hearing‐impaired children are able to use procedures to process the written word based on the alphabetic principle, but continuous support‐implying invented spelling constantly adjusted to the progression of their representations must be provided.     

13‐year‐olds’ perception of bullying: definitions,reasons for victimisation and experience of adults’ response

This study formed the second wave of a longitudinal research project examining bullying from the students’ perspective. A sample of 877 Swedish 13‐year‐olds filled out a questionnaire regarding the definition of bullying, reasons for why some students are bullied and the experience of adults’ response to bullying. In their definitions, girls were more likely than boys to include the victims’ experience of bullying, whereas boys were more likely than girls to mention bullying as an imbalance of power and a set of repeated actions. Assigning responsibility for the bullying to the bully was more common among girls and bullied adolescents than among boys and non‐bullied adolescents. Furthermore, among bullied adolescents, 23% had not told anyone about the bullying and 35% had not received any help.     

Dangerous spaces: constructing and contesting sexual identities in an online discussion forum

This paper explores ways in which the research design of an anonymous online discussion forum on sexual orientation and schooling fostered the creation, maintenance and/or disruption of linguistic constructions of participant identity. The paper focuses on the presentation of self and the performance of sex–gender–sexuality within a research environment carefully designed as a ‘safe space’: an environment in which the body is conspicuous by its absence, and the construction and performance of identity relies on language alone. We explore the lines of power operating firstly between ourselves as researchers and the discussion participants, and secondly between the participants themselves, and consider the particular complexities involved in both creating and researching an online environment where simply to take part is to be at risk, and where the intervention or participation of the researchers may act both as a silencing mechanism and as a source of danger.
