The Acquisition of Communication Skills by People with Brain Injury: Some comparisons with children with autism

This research identifies the extent to which different contexts shape and modify the language and behaviours of four people with acquired brain injury. Comparisons are made with factors which can influence the language acquisition of children with autism because it is postulated that children with autism also have a particular brain injury. The comparison does not end there as the criteria for effective management necessary to nourish the communication skills of both groups appears similar. The four contexts used to shape and evaluate the language of people with brain injury include their own home, a residential camp with maximum support and enriched activity, a post camp period with comparable support, followed by a return to their own home with very limited support. Measures of communication skills demonstrate the success of the enriched camp facility. This was characterised by planning, structured support, and expectation of success from the participants. Their motivation and ability to communicate generally far exceeded the communication skills that each person with brain injury demonstrated when organised activity and sustained support is not available.     

Comparison of individual factors in school psychology graduate students: Why do students pursue a degree in school psychology?

The purpose of this study was to investigate what factors influenced students to enter the field of school psychology. Although numerous studies have documented the thoughts and perspectives of practitioners regarding why they have chosen to become school psychologists, attempts to recruit and retain an adequate number of school psychology practitioners and researchers have shown limited success. A national sample of 307 school psychology graduate students responded to a survey designed to measure issues related to the current state of professional practice, the influence of parental education, and professional organization recruitment. Results indicated that working with children and personal experiences within the school system were highly related to participant's decisions to become school psychologists. In addition, doctoral level and nondoctoral level students present similar reasons for entering the field. This research is discussed in terms of its implications for future research and the current shortage of school psychology practitioners and faculty. © 2007 Wiley Periodicals, Inc.

Extinction and food-reinforced inhibition of conditioned salivation in dogs

The present experiment compared two methods of eliminating a classically conditioned response in dogs, extinction and reinforcement of nonsalivation, using both a within- and between-subjects experimental design. Eighteen dogs were trained for 16 days in Phase I, 16 days in Phase II, and 8 days in Phase III. In Phase I, each subject received classical conditioning training to two stimuli. In Phase II, Group 1 received extinction training to one stimulus and reinforcement of nonsalivation to the other stimulus. Group 2 received continued classical conditioning training to one stimulus and reinforcement on nonsalivation training to the other. Group 3 received continued classical conditioning training to one stimulus and extinction training to the other. In both the within- and between-subjects comparisons, responding to the stimulus associated with extinction was eliminated faster than responding to the stimulus associated with reinforcement of nonsalivation.

Comparing active delay and procrastination from a self-regulated learning perspective

Researchers have proposed that the act of postponing academic work may be divided into a traditional definition of procrastination, viewed as maladaptive, and adaptive forms of delay. Adaptive forms of delay may be more consistent with certain facets of self-regulated learning. The current study investigated this issue by examining whether the relations between aspects of self-regulated learning and active delay may be distinct from the relations these aspects of self-regulated learning have with procrastination. Among 206 undergraduates, procrastination was positively predicted by mastery-avoidance goals and negatively by metacognitive strategy usage, whereas active delay was negatively predicted by avoidance goals and positively by self-efficacy. Furthermore, students who reported higher levels of active delay also received better grades. These findings provide support that active delay is a distinct form of delay from procrastination that may be more positive due to its associations with some adaptive self-regulatory processes and academic achievement.     

The design of motivational agents and avatars

While the addition of an anthropomorphic interface agent to a learning system generally has little direct impact on learning, it potentially has a huge impact on learner motivation. As such agents become increasingly ubiquitous on the Internet, in virtual worlds, and as interfaces for learning and gaming systems, it is important to design them to optimally impact motivation. The focus of this paper is on the design of agents and avatars (one’s self-representation as a visual agent) for enhancing motivational and affective outcomes, such as improving self-efficacy, engagement and satisfaction, moderating frustration, and/or improving stereotypes. Together with motivational messages and dialogue (which are not discussed here), the agent’s appearance is the most important design feature as it dictates the learner’s perception of the agent as a virtual social model, in the Bandurian sense. The message delivery, through a human-like voice with appropriate and relevant emotional expressions, is also a key motivational design feature. More research is needed to determine the specifics with respect to the ideal agent voice and the role of other nonverbal communication (e.g., deictic gestures) that may contribute to the agent’s role as an embodied motivator, particularly in the long-term.     

If We Teach Them, They Can Learn: Young Students Views of Nature of Science During an Informal Science Education Program

There have been substantial reform efforts in science education to improve students’ understandings of science and its processes and provide continual support for students becoming scientifically literate (AAAS, Benchmarks for science literacy, Oxford University Press, New York, 1993; NRC, National Academy Press, Washington, DC, 1996; NSTA, NSTA position statement: The nature of science, , 2000). Despite previous research, it is still unclear whether young children are actually developmentally ready to conceptualize the ideas that are recommended in the reforms (Akerson and Volrich, J Res Sci Teach 43:377–394, 2006). The purpose of this study was to explore how explicit-reflective instruction could improve young students’ understanding of NOS. During an informal education setting, the authors taught NOS aspects using explicit-reflective instruction. Overall the students participating in the program improved their understanding of the target aspects of NOS through use of explicit reflective instruction. However, the levels of improvement varied across different aspects. Students improved the most in their understanding of the tentative nature of science and the roles of observation in scientific work, although there was still some confusion regarding the distinction between observation and inference. More work needs to be done exploring these specific topics and the role explicit reflective practice can play in identifying the particular problems students have in distinguishing these constructs.
