Using performance feedback to improve treatment integrity of classwide behavior plans: an investigation of observer reactivity

The current study replicated the positive effects of performance feedback on treatment integrity and extended previous work by examining reactivity using a multiple baseline design with alternating treatments for observer-present and observer-absent conditions on teachers' implementation of a classwide behavior plan. No differences were found between conditions, and treatment integrity improved across all teachers, suggesting that performance feedback, rather than observer reactivity, was responsible for reported behavior changes.     

Development and factor analysis of the Coaching and Athletic Training Questionnaire

To explore athletes' perceptions related to coaching and athletic training care, the Coaching and Athletic Training Questionnaire was developed. A 10-item version was administered to 708 varsity athletes from three Division I universities in the National Collegiate Athletic Association. 341 women and 344 men completed questionnaires. Data from half of the sample of 685 were used for an exploratory factor analysis using principal components analysis with oblique rotation and the second half for a confirmatory factor analysis. Analyses yielded three interpretable factors, accounting for 68% of the variance, which were labeled Comfort with Athletic Trainer or Coach, Sex Influence on Quality of Care, and Athletic Trainer Preference. Multivariate analysis of variance indicated that factor scores of women and men differed significantly, and at followup women and men differed significantly on Comfort with Athletic Trainer or Coach, but the small effect size minimizes its meaningfulness. No significant difference was noted for the other two factors. It appears coaches should be sensitive and available in case of injury or other need. Athletes' perceived quality of care by athletic trainers does not appear related to sex of athlete or trainer.     

Determinants of linear judgment: a meta-analysis of lens model studies

The mathematical representation of E. Brunswik's (1952) lens model has been used extensively to study human judgment and provides a unique opportunity to conduct a meta-analysis of studies that covers roughly 5 decades. Specifically, the authors analyzed statistics of the "lens model equation" (L. R. Tucker, 1964) associated with 249 different task environments obtained from 86 articles. On average, fairly high levels of judgmental achievement were found, and people were seen to be capable of achieving similar levels of cognitive performance in noisy and predictable environments. Further, the effects of task characteristics that influence judgment (numbers and types of cues, inter-cue redundancy, function forms and cue weights in the ecology, laboratory versus field studies, and experience with the task) were identified and estimated. A detailed analysis of learning studies revealed that the most effective form of feedback was information about the task. The authors also analyzed empirically under what conditions the application of bootstrapping--or replacing judges by their linear models--is advantageous. Finally, the authors note shortcomings of the kinds of studies conducted to date, limitations in the lens model methodology, and possibilities for future research.     

Visuomotor tracking abilities of speakers with apraxia of speech or conduction aphasia

This investigation examined the visuomotor tracking abilities of persons with apraxia of speech (AOS) or conduction aphasia (CA). In addition, tracking performance was correlated with perceptual judgments of speech accuracy. Five individuals with AOS and four with CA served as participants, as well as an equal number of healthy controls matched by age and gender. Participants tracked predictable (sinusoidal) and unpredictable signals using jaw and lip movements transduced with strain gauges. Tracking performance in participants with AOS was poorest for predictable signals, with decreased kinematic measures of cross-correlation and gain ratio and increased target-tracker difference. In contrast, tracking of the unpredictable signal by participants with AOS was performed as well as for other groups (e.g. participants with CA, healthy controls). Performance of the subjects with AOS on the predictable tracking task was found to strongly correlate with perceptual judgments of speech. These findings suggest that motor control capabilities are impaired in AOS, but not in CA. Results suggest that AOS has its basis in motor programming deficits, not impaired motor execution.     

Discussions of Diversity in a Classroom: A Phenomenological Study of Students in an MFT Training Program

Discussions about diversity, particularly race, gender, religion and spirituality, and sexual orientation, in marriage and family therapy courses can generate emotional responses in students and professors that vary from shame to anger. These discussions are necessary to help students understand diverse families as well as how one’s biases can affect his/her clinical work. Our qualitative study consisted of phenomenological interviews, which focused on discussions of diversity by six students from a marriage and family therapy program. Findings revealed that the ability of students to be aware of and discuss their reactions to these discussions is complex and influenced by their families of origin, their perceptions of other students, their views of the professor, and their race. Teaching implications are discussed in light of these findings.     

Salience and temporal sequencing of time-related actions in boys with attention deficit/hyperactivity disorder.

Twenty-four 8- to 12-year-old boys with ADHD and 24 non-ADHD boys matched on age and IQ viewed an edited, nondialogue portion of a humorous television program to examine performance on a task requiring attention to and recall of temporal information. Participants were required to retell the story as closely as possible, to complete a picture-prompted sequencing task taken from the story, and to identify time-saving actions taken by the central character. Measures were also obtained of the number of prospective, retrospective, or present time-related references made and whether participants correctly identified the overarching time theme of the story. Significant group differences in favor of the comparison boys were evident in the total number of actions recalled and the number of events recalled in sequence. When controlling for poorer memory performance in boys with ADHD, however, there was no significant main effect of diagnostic group. A logistic regression analysis controlled for poorer memory performance indicated no significant differences between the number of boys with and without ADHD who correctly identified the overarching time theme of the story.     

The Effects of Coaching on Mathematics Homework Completion and Accuracy of High School Students with Attention-Deficit/Hyperactivity Disorder

As many as 30% of children with Attention-Deficit/Hyperactivity Disorder (AD/HD) do not achieve academically at the level predicted by their age or IQ. One of the variables that may contribute to their poor academic performance is homework completion. Unfortunately, a paucity of research has investigated interventions that address homework problems, particularly at the secondary level. The purpose of this study was to investigate the effects of a coaching intervention that incorporated self-monitoring, goal-setting, and systematic fading on the homework completion and accuracy of three high-school students diagnosed with AD/HD. Results suggest that coaching led to improvements across all three students. Performance was maintained during fading and post-treatment for the two students for whom it was examined.
