The role of habituation of the response to LiCl in the US-preexposure effect

In two experiments, rats received preexposure consisting of six intraperitoneal injections of lithium chloride (LiCl). This treatment reduced the magnitude of the unconditioned response (UR; suppressed consumption of a novel flavor) evoked by an additional injection (Experiment 1) or by oral consumption (Experiment 2) of LiCl. In both experiments, preexposure also attenuated the acquisition of a conditioned aversion with an LiCl injection as the unconditioned stimulus (US) but had no effect on the aversion produced when the US was oral consumption of LiCl (Experiment 2). These results are consistent with the view that the reduced ability of the preexposed US to serve as a reinforcer depends on blocking by injection-related cues and is independent of habituation of the UR recorded in the present study. Possible interpretations of this dissociation are discussed.     

The Predictive Value of Non-Referential Beat Gestures: Early Use in Parent–Child Interactions Predicts Narrative Abilities at 5 Years of Age

A longitudinal study with 45 children (Hispanic, 13%; non-Hispanic, 87%) investigated whether the early production of non-referential beat and flip gestures, as opposed to referential iconic gestures, in parent–child naturalistic interactions from 14 to 58 months old predicts narrative abilities at age 5. Results revealed that only non-referential beats significantly (p < .01) predicted later narrative productions. The pragmatic functions of the children’s speech that accompany these gestures were also analyzed in a representative sample of 18 parent-child dyads, revealing that beats were typically associated with biased assertions or questions. These findings show that the early use of beats predicts narrative abilities later in development, and suggest that this relation is likely due to the pragmatic–structuring function that beats reflect in early discourse.     

Insightful Learning of Life's Lessons with Older Adult Guests in the Classroom

An intergenerational initiative was developed and implemented to enhance gerontology in the first course of the practice sequence. Seventeen students met with older adults (ages 82–98) in the classroom and at an assisted living facility. The evaluation of this older adult infusion project was conducted through two questionnaires and by the review of reflection papers completed as a course assignment. Pre-post statistical analyses as well as qualitative analysis evidenced an increase in knowledge of the older adults' lives as well as a professional interest in aging. As a result of this experience, several of the students volunteered at the facility, interviewed residents, and requested gerontological placements.     

Developing an audiovisual notebook as a self‐learning tool in histology: Perceptions of teachers and students

Videos can be used as didactic tools for self‐learning under several circumstances, including those cases in which students are responsible for the development of this resource as an audiovisual notebook. We compared students' and teachers' perceptions regarding the main features that an audiovisual notebook should include. Four questionnaires with items about information, images, text and music, and filmmaking were used to investigate students' (n = 115) and teachers' perceptions (n = 28) regarding the development of a video focused on a histological technique. The results show that both students and teachers significantly prioritize informative components, images and filmmaking more than text and music. The scores were significantly higher for teachers than for students for all four components analyzed. The highest scores were given to items related to practical and medically oriented elements, and the lowest values were given to theoretical and complementary elements. For most items, there were no differences between genders. A strong positive correlation was found between the scores given to each item by teachers and students. These results show that both students' and teachers' perceptions tend to coincide for most items, and suggest that audiovisual notebooks developed by students would emphasize the same items as those perceived by teachers to be the most relevant. Further, these findings suggest that the use of video as an audiovisual learning notebook would not only preserve the curricular objectives but would also offer the advantages of self‐learning processes.

Attitudes toward an enemy and personality in a war environment

The aim of the present study was to investigate the effects of war environment on political attitudes toward an enemy and on personality development. High school students from an Israeli town on the border of “Fatahland” and a town in central Israel were asked to fill out: A questionnaire on their political views toward the Israel-Arab conflict and the Repression-Sensitization (R-S) scale (Byrne et al., 1963). Results showed three factors in the students' political views: (a) Return of the Controversial Territories (Samaria, Judea, Gaza Strip, Golan Heights and Sinai); (bj Credibility of the Arabs in negotiation; (c) The policy of the previous government in its return of certain territories in Sinai.It was found that the students in the border town were less opposed to return the Controversial Territories than the students in the non-border town. Repressers in both towns gave more credibility to the Arabs in negotiation than did sensitizers. Girls agreed more with the policy of the previous government in its return of the territories in Sinai than boys. Results also showed that the students in the border area as well as boys in both towns were more repressive in their personality type than the students in the more peaceful area and girls of both towns respectively.     

International collaborations in learning and teaching: perspectives from a visiting professorship

This article provides a reflection on the outcomes of an international collaboration between health librarians and academics at York St John University and Pacific University Oregon. In particular, it describes how a month‐long visiting professorship from an academic with a clinical librarian background at the Faculty of Health and Life Sciences helped to develop and inform teaching practice in the areas of information literacy and evidence‐based health practice on health programmes at Pacific University. Perspectives are offered from both institutions on the rich exchange of knowledge and practice that took place during the visit and the ongoing impact it has had on teaching practices. H. S.     

The Influence of Media Type on the Perceived Influence of Media Contents and on the Support to Restrict Controversial Messages

The aim of this study was to explore the intersection between Medium Theory (MT) and Third-Person Effect (TPE) and evaluate how the research on MT can further our knowledge of the TPE. The study has proven that the perceptual hypothesis of the TPE is confirmed in different media contents and across media types (TV and the Internet) and that media type has an impact on the magnitude of the TPE. In addition, media type can also be a requisite for TPE to occur. On the other hand, the study shows that media type can have an influence on people’s support to restrict controversial content, in particular, pornography.
