Training effects on dual-task performance: are there age-related differences in plasticity of attentional control?

A number of studies have suggested that attentional control skills required to perform 2 tasks concurrently become impaired with age (A. A. Hartley, 1992; J. M. McDowd & R. J. Shaw, 2000). A. A. Hartley (2001) recently observed that the age-related differences in dual-task performance were larger when the 2 tasks required similar motor responses. The present study examined the extent to which age-related deficits in dual-task performance or time sharing--in particular, dual-task performance of 2 discrimination tasks with similar motor requirements--can be moderated by training. The results indicate that, even when the 2 tasks required similar motor responses, both older and younger adults could learn to perform the tasks faster and more accurately. Moreover, the improvement in performance generalized to new task combinations involving new stimuli. Therefore, it appears that training can substantially improve dual-task processing skills in older adults.     

A reexamination of stimulus-frequency effects in recognition: two mirrors for low- and high-frequency pseudowords

The word-frequency mirror effect (more hits and fewer false alarms for low-frequency than for high-frequency words) has intrigued memory researchers, and multiple accounts have been offered to explain the result. In this study, participants were differentially familiarized to various pseudowords in a familiarization phase that spanned multiple weeks. Recognition tests given during the first week of familiarization replicated a result of W. T. Maddox and W. K. Estes (1997) that failed to show the classic word-frequency mirror effect for pseudowords; however, recognition tests given toward the end of training showed the classic mirror pattern. In addition, a stimulus-frequency mirror effect for "remember" vs. "know" judgments was obtained. These data are consistent with an account of the mirror effect that posits the involvement of dual processes for episodic recognition.     

Honoring and Privileging Personal Experience and Knowledge: Ideas for a Narrative Therapy Approach to the Training and Supervision of New Therapists

This article discusses an approach for the training and supervision of new therapists built around social constructionist and poststructuralist ideas from a narrative therapy perspective. We briefly discuss some of the pitfalls of current training/supervision in marriage and family therapy (MFT) that are deficit based and/or that disproportionately grant privilege to expert knowledge. We articulate this emerging training approach which utilizes the rite of passage metaphor, centers relationalism, and incorporates the honoring and privileging of new therapists' lived experience, knowledges, skills, talents, ideas, morals, personal ethics, values, beliefs. Concrete practices of experience privileging, re-membering, and creating communities of concern are detailed, and illustrative examples from our supervision work are given.     

The Utility of the State Space Grid Method for Studying Peer Interactions in Youth Sport

Although previous studies indicate that peer interactions represent an important component of the youth sport experience, studies examining peer interactions in the sport context are limited. Furthermore, the methodological tools commonly used to investigate peer interactions have restricted researchers’ understandings of the complex, reciprocal nature of these experiences. This paper outlines the potential contribution of a novel dynamic systems-based methodology, the state space grid method (SSG; Lewis, Lamey, & Douglas, 1999 Lewis, M. D., Lamey, A. V. and Douglas, L. 1999. A new dynamic system method for the analysis of early socioemotional development. Developmental Science, 2: 457–475. [Crossref], [Web of Science ®] , [Google Scholar]), to the study of peer interactions in sport. Concrete recommendations to guide the practical application of the SSG method to future peer research in youth sport are presented.
