Working with Low Survey Response Rates: The Efficacy of Weighting Adjustments

National data show a continuing decline in the willingness of people to respond to surveys. This trend is troubling given the central role that survey research plays in collecting data for institutional research purposes. This paper examines the effectiveness of a weighting procedure described by Astin and Molm for adjusting survey results to correct for nonresponse bias. Using data from a Cooperative Institutional Research Program (CIRP) follow-up survey, the results indicate that the weighting procedure is highly effective at reducing nonresponse bias in univariate distributions. The effectiveness of the weighting procedure in adjusting correlation and regression analyses is less clear. This may be due in part to the observation that even when individual variables are noticeably biased, their relationships with each other tend not to be.     

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.     

Self-assessments and other perceptions of successful adults who are deaf: an initial investigation

More often than not, deafness is portrayed, not only in the literature in education and rehabilitation but in society in general, in a pathological way that focuses on deficiency, dysfunction, and deviance. Consequently, there has been a paucity of research on successful individuals who are deaf. The purpose of the present study was to help counter this tendency by gathering information from successful deaf adults. Fourteen deaf adults, who were nominated by their peers as being successful, participated in videotaped interviews. The interviews were transcribed, coded, and clustered according to common themes. Participants reflected on their success and made recommendations for children and youth who are deaf, parents, teachers, and employers. A summary of the results, limitations of the study, and recommendations for practice are provided.     

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.

The evaluation from the program director's viewpoint

In considering the evaluation of the preceptorship and residency programs, our faculty were asked to react to specific dimensions and aspects of the studies. Viewpoints about these data were submitted in formal critiques which will be summarized only briefly here. A number of the comments were in response to specific questions which had been posed; other were spontaneous from the faculty.     

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.
