Counterconditioning of memory in rats

Two experiments examined the counterconditioning of an aversively motivated response in rats. Presentation of a highly palatable sugar solution (maltose in Experiment 1; sucrose in Experiment 2) to thirsty rats was used as the counterconditioning treatment. In Experiment 1, the counterconditioning procedure was found to be effective in modifying both a newly acquired and a cue-reactivated fear memory. In Experiment 2, the counterconditioning effect was shown to occur when the fear memory was reactivated with a noncontingent exposure to the unconditioned stimulus rather than the conditioned stimulus. This outcome supports the interpretation of counterconditioning as a modification of some central representation of the original training memory, rather than the acquisition of a competing peripheral response. The methodological implications of the present approach to counterconditioning are considered.     

A TECHNICAL COLLEGE'S RESPONSE TO THE NEED FOR INTERNATIONALIZING EDUCATIONAL PROGRAMS AND SERVICES

Part of the mission of the American Association of Community Colleges addresses the need for a curriculum emphasis on international and intercultural education (Wismer, 1994, p. 77). Considering that (a) 2‐year colleges exist primarily to prepare students for jobs, (b) many American businesses operate in an international environment, and (c) a growing proportion of companies in the United States are foreign affiliated, the internationalization of our curriculums is necessaryforthe fulfillment of institutional missions of preparing the workforce for businesses. However, to fully internationalize college programs and services, the focus must be on more than courses and curriculums. The everyday life of college students, faculty, and staff must present evidence of cultural diversity. Internationalization, therefore, must be infused at every level of college activity. Such an infusion is occurring at Florence‐Darlington Technical College in Florence, South Carolina. There are four broad categories within which activities are planned or are underway: (a) resource development, (b) awareness development and information dissemination, (c) faculty and staff development, and (d) curriculum development. The importance of the need for this South Carolina college to undertake internationalizing initiatives is underscored by the multicultural business environment that exists in the state. For many years, international investment has created record levels of new employment opportunities for South Carolinians and has contributed significantly to statewide economic and industrial growth. The economic impact of international business in the state is apparent. However, there is also a cultural impact that is less obvious, yet profound. These factors present some definite implications for the need to internationalize technical college programs and services.     

Civic learning: moving from the apolitical to the socially just

This study examines the knowledge and skills that characterize civic learning for young people. Building on a literature review, it reports an exploratory case study with students and teachers in four secondary schools in the Ottawa, Canada region. The perspectives of researchers co‐operating with educators and students against a backdrop of provincial government curricula and secondary literature on youth citizenship engagement provide an enriched understanding of the state and potential of civic learning. It concludes that current civic learning is primarily characterized by procedural knowledge and compliant codes of behaviour that do not envelope students in collective action for systemic understandings of political issues. This study argues for renewed efforts to put social justice at the heart of student learning. To present a convincing civic educational programme, schools should prepare students to analyse power relationships, investigate the ambiguities of political issues, and embrace opportunities for social change.

Emotional Feeding and Emotional Eating: Reciprocal Processes and the Influence of Negative Affectivity

Emotional eating, that is, eating more in response to negative mood, is often seen in children. But the origins of emotional eating remain unclear. In a representative community sample of Norwegian 4‐year‐olds followed up at ages 6, 8, and 10 years (analysis sample: n = 801), one potential developmental pathway was examined: a reciprocal relation between parental emotional feeding and child emotional eating. The results revealed that higher levels of emotional feeding predicted higher levels of emotional eating and vice versa, adjusting for body mass index and initial levels of feeding and eating. Higher levels of temperamental negative affectivity (at age 4) increased the risk for future emotional eating and feeding.     

Factor structure,reliability and validity of the Parental Support for Learning Scale: Adolescent Short Form (PSLS-AS)

Parental involvement in children’s learning has been found to influence academic success. However, very few tools exist for measuring parental involvement, particularly ones that target adolescents’ self-report. The present study assessed the factor structure, reliability and convergent validity of a new scale to assess adolescents’ perceptions of their mothers’ and fathers’ educational involvement: the Parental Support for Learning Scale: Adolescent Short Form (PSLS-AS). The PSLS-AS, as well as a questionnaire measuring the risk of high school drop-out, was administered to a sample of 825 youth (aged 13–14 years). Exploratory factor analysis revealed a two-factor structure representing parental involvement: Controlling Involvement and Autonomy Supportive Involvement. Adolescents’ perceptions of their parents’ involvement correlated with a risk of high school drop-out. Implications and future directions for further validation of the PSLS-AS are discussed.     

State-dependent retention induced by postacquisition exposure to pentobarbital or shock stress in rats

Although state-dependent retention (SDR) has been the focus of considerable research in recent years, there has been little work demonstrating this phenomenon when the treatment is administeredafter learning. In the present study, the effectiveness of two different treatments, pentobarbital and shock-induced stress, in producing postacquisition SDR in rats was examined. In all experiments, water-deprived rats were exposed to a novel flavor, apple juice, on each of 2 days. Subjects that remember their initial exposure to this substance should show an increase in consumption on their second exposure (i.e., an attenuation of neophobia). It was found that subjects exposed to pentobarbital (Experiment 1) or shock-induced stress (Experiment 2) immediately after their initial exposure did not increase their intake on the subsequent exposure unless they were reexposed to pentobarbital (Experiment 1) or shock-induced stress (Experiment 2b) shortly prior to that exposure. These results clearly show that this “attenuation of neophobia” paradigm can be used to investigate postacquisition SDR.     

Social comparison and persuasive arguments as determinants of group polarization

In a study of group polarization, Boster and Mayer (1984) found that social comparison information influenced perception of persuasive argument information. In their investigation, however, position of majority was confounded with other of presentation. The present study attempted to replicate Boster and Mayer while varying order of presentation. Results of the present investigation, first, support the persuasive arguments explanation of group polarization. Second, results are inconsistent with an order effect. Finally, results indicate a parallel between the group polarization literature and the cognitive response literature in persuasion.
