Further evidence that conditioned inhibition is not the mechanism of an extinction cue’s effect: A reinforced cue prevents spontaneous recovery

Previous research has demonstrated that discrete cues presented during extinction of a conditioned response (extinction cues) subsequently reduce spontaneous recovery and the renewal effect. In order to assess whether an extinction cue’s effect is due to conditioned inhibition, the effect of pairing an extinction cue with food on the cue’s capacity to modulate spontaneous recovery was investigated in an appetitive conditioning experiment with rats. Conditioned inhibitors paired with the unconditioned stimulus lose their potential to inhibit responding. The food-paired extinction cue did not lose its potential to reduce spontaneous recovery. In fact, it reduced spontaneous recovery more than did an extinction cue that was not paired with food. The results indicate that extinction cues attenuate postextinction recovery of conditioned responding through a mechanism other than conditioned inhibition. The cue’s action appears to be similar to that of serial negative occasion setters. Theories of spontaneous recovery and the relationship of extinction cues to other modulatory stimuli are discussed.     

Students as political actors? Similarities and differences across six European nations

Drawing on data from students, higher education staff and policymakers from six European countries, this article argues that it remains a relatively common assumption that students should be politically engaged. However, while students articulated a strong interest in a wide range of political issues, those working in higher education and influencing higher education policy tended to believe that students were considerably less politically active than their predecessors. Moreover, while staff and policy influencers typically conceived of political engagement in terms of collective action, articulated through common reference to the absence of a ‘student movement’ or unified student voice, students’ narratives tended not to valorise ‘student movements’ in the same way and many categorised as ‘political’ action they had taken alone and/or with a small number of other students. Alongside these broad commonalities across Europe, the article also evidences some key differences between nation-states, institutions and disciplines. In this way, it contributes to the comparative literature on young people’s political engagement specifically, as well as wider debates about the ways in which higher education students are understood.     

A Comparative Study or Western and Japanese Practices Geared Towards Improved Learning and New Product Performance

Increasingly, the long‐term success of a company resides in its ability to develop and market successful new products in a cost‐and time‐effective manner. In general, Japanese companies have outperformed their Western counterparts in bringing new products to market over the last 10 to 20 years. This has given them a substantial advantage in long‐term economic development. The authors hypothesize that the differences between the dominant models of corporate culture in Japan and the U.S. account for the Japanese advantage. In comparison to U.S. companies, Japanese companies tend to emphasize long‐term leadership, decentralized decision making, a flatter work structure using cross‐functional work teams, and rewarding teams for the ability to learn from mistakes. As a result of these differences, Western companies are more likely to utilize “single, loop” learning, where new products are developed using established (and unquestioned) procedures. Conversely, Japanese companies rely on “double‐loop” or “deutero” learning styles, which encourage employees to leverage their past experiences when proposing new product innovations. The authors conclude by outlining a research program for testing their as‐gumptions about the relations among nationality, corporate culture, learning styles, and new product success.     

An Internet-Based Course: Leadership Issues

It comes as no surprise that persons in leadership roles face many decisions related to providing distance learning experiences, especially ones centered on the Internet. In this paper we will try to focus upon leadership issues that arose during the creation and offering of an Internet-based course for high school chemistry teachers. One of us served as the department chair, another as the professor of record and course designer, and the third as a researcher who developed a systematic case study of the course.     

Reasons for Student Engagement in Extra-Class Communication

This study extends instructional communication research on extra-class communication (ECC) by presenting an integrative analysis comparing the explanatory utility of student- and instructor-oriented reasons for student engagement in frequent ECC. Results from 495 college students suggested that student-oriented reasons, specifically the relational and functional student motives, were the only significant, positive predictors of students’ perceptions of frequent ECC engagement. Other student motives (excuse making, participation, sycophancy) and perceptions of instructor approachability did not significantly predict perceived frequency of ECC engagement.     

Oral Communication Skills in Higher Education: Using a Performance-Based Evaluation Rubric to Assess Communication Skills

This study used The Competent Speaker, a rubric developed by the National Communication Association (S. P. Morreale, M. R. Moore, K. P. Taylor, D. Surges-Tatum, & R. Hulbert-Johnson, 1993), to evaluate student performance in general education public speaking courses as a case study of student skills and programmatic assessment. Results indicate that students taking the general education public speaking course are below satisfactory standards on five of the eight competencies defined by the National Communication Association and are above satisfactory standards on two of the eight competencies. Implications for this particular program, other communication departments, and communication across the curriculum in general education are discussed. We also offer suggestions for those in other disciplines or educational settings in the use of performance evaluation rubrics for assessing other student skills/knowledge and for training new teachers.

Investigating a Method of Scaffolding Student-Designed Experiments

The process of designing an experiment is a difficult one. Students often struggle to perform such tasks as the design process places a large cognitive load on students. Scaffolding is the process of providing support for a student to allow them to complete tasks they would otherwise not have been able to complete. This study sought to investigate backwards-design, one form of scaffolding the experimental design process for students. Students were guided through the design process in a backwards manner (designing the results section first and working backwards through typical report components to the materials and safety sections). The use of reflective prompts as possible scaffold for metacognitive processes was also studied. Scaffolding was in the form of a computer application built specifically for this purpose. Four versions of the computer application were randomly assigned to 102 high school chemistry students and students were asked to the design of an experiment, producing a report. The use of backwards-design scaffolding resulted in significantly higher performance on lab reports. The addition of reflective prompts reduced the effect of backwards-design scaffolding in lower-level students.     

Working Memory, Motivation, and Teacher-Initiated Learning

Working memory is where we “think” as we learn. A notion that emerges as a synthesis from several threads in the research literatures of cognition, motivation, and connectionism is that motivation in learning is the process whereby working memory resource allocation is instigated and sustained. This paper reviews much literature on motivation and working memory, and concludes that the apparent novelty of the proposal offered to describe motivation in terms of working memory results from the apparent lack of cross-channel exchange among these research traditions. The relation between working memory and motivation is explored in the context of the interactive compensatory model of learning (ICML) in which learning is considered to result from the interaction of ability, motivation, and prior learning. The ICML is recast in light of the revised definition of motivation offered here. This paper goes on to suggest ways in which a range of teaching and learning issues and activities may be reconceptualized in the context of a model emphasizing a learner's working memory that makes use of chunks of previously acquired knowledge.
