Research Report: Correlates of learning styles and counsellor trainees' age and gender

Counselling relationships are important indices of therapeutic efficacy. In the Fall 2001, 71 counsellor trainees in a Counsellor Education programme at a Mid-western university participated in the current investigation. The purpose of the study was to examine relationships of learning styles in terms of counsellor trainees' age and gender (using a recently developed Preferred Learning Style Inventory, namely KPLSI). Results of the present study suggest that counsellor trainees' learning styles are varied, except that there are statistically strong groupings in analytic, global and particularistic learning styles domains among this particular body of students. Additionally, the age of trainees tend to relate to superficial and sensational learning styles, whereas gender is, participatory.     

Programmatic prevention of adolescent problem behaviors: The role of autonomy,relatedness, and volunteer service in the teen outreach program

Explored the mechanisms by which a well-validated intervention to prevent school failure, suspension, and teenage pregnancy produces its effects, using site-level data from 66 sites involving over 1,000 students participating in national replication of the Teen Outreach Program. Multiple informants provided data on operating characteristics of each site. These were then used to explain differences across sites in levels of success in reducing youth problem behaviors using a pre-post design and a well-matched comparison group. In accord with predictions from developmental theory, middle school sites that promoted student autonomy and relatedness with peers and with site facilitators achieved significantly greater levels of success in reducing problem behaviors. Offering volunteer experiences perceived as teaching middle school students new skills and leaving them real choices about the type of work they did was also linked to program success. Although the program was equally sucessful with students from a wide range of sociodemographic backgrounds, links of program factors to site-level outcomes were found only for middle school but not high school sites. Implications of these findings for the development of programmatic interventions targeted at adolescents are discussed. The Teen Outreach program and its evaluation have been supported by grants from the Charles Stewart Mott Foundation, the Lila Wallace Reader's Digest Fund and other sources. We also thank the Association of Junior Leagues International, local Junior Leagues around the country, and the students and facilitators who made this program possible. The Spencer and W. T. Grant Foundations also provided support to the first author for the write-up of this study.     

Differential cognitive substrates of verbal episodic memory performance in semantic variant primary progressive aphasia and Alzheimer’s disease

Performance on neuropsychological measures of verbal memory requires cognitive abilities beyond memory. We examined the contribution of semantic knowledge in verbal episodic memory for semantic variant primary progressive aphasia (svPPA) or Alzheimer’s disease (AD). 415 AD and 68 svPPA participants completed measures of episodic memory (visual and verbal) and semantic knowledge. A double dissociation existed visual recall predicted verbal recognition in AD, whereas semantic knowledge contributed to verbal recognition in svPPA.     

Linguistics and the explanatory economy

I present a novel, collaborative, methodology for linguistics: what I call the ‘explanatory economy’. According to this picture, multiple models/theories are evaluated based on the extent to which they complement one another with respect to data coverage. I show how this model can resolve a long-standing worry about the methodology of generative linguistics: that by creating too much distance between data and theory, the empirical credentials of this research program are tarnished. I provide justifications of such methodologically central distinctions as the competence/performance and core/periphery distinction, and then show how we can understand the push for simplicity in the history of generative grammar in this light.
