Toddlers can adaptively change how they categorize: same objects,same session,two different categorical distinctions

Two experiments demonstrate that 14‐ to 18‐month‐old toddlers can adaptively change how they categorize a set of objects within a single session, and that this ability is related to vocabulary size. In both experiments, toddlers were presented with a sequential touching task with objects that could be categorized either according to some perceptually salient dimension corresponding to a taxonomic distinction (e.g. animals vs. vehicles) or to some less obvious dimension (e.g. rigid vs. deformable). In each experiment, children with larger productive vocabularies responded to both dimensions, showing evidence of sensitivity to each way of categorizing the items. Children with smaller productive vocabularies attended only to the taxonomically related categorical grouping. These experiments confirm that toddlers can adaptively shift the basis of their categorization and highlight the dynamic interaction between the child and the current task in early categorization.     

REJOINDER: WHITHER MARITAL THERAPY?

It is apparent that Gurman and Kniskern have greatly revised their original position in response to our critique. We believe that their revised position is more fully consonant with the available empirical evidence, although certain areas of disagreement between us are still evident. Overall, we believe that this dialogue has generated some promising lines for future research and clinical practice.     

Primary Prevention Mental Health Programs: The Future is Exciting

Current outcome research on primary prevention mental health programs is encouraging and the future is exciting. Data continue to accumulate regarding the efficacy of preventive intervention. Exemplary programs can prevent multiple problems across different outcome domains suggesting the need for collaboration among preventionists across disciplines and research areas. The commentators on our review (Durlak and Wells, 1997) offered many useful suggestions to improve the next generation of research. Most recommendations fall broadly under the rubric of increasing the precision of theory, design, and program evaluation. If current recommendations for improving future research are followed, the next reviewers of primary prevention mental health programs for children and adolescents will have a more complete and useful database for analysis.     

The family-of-origin framework: A model for clinical training

Family-of-origin work is defined as a person's attempt to examine and/or change the patterns of interaction that occur in the family in which s/he was raised. This article outlines a model of family-of-origin work that is used in the clinical psychology training program at St. Louis University. The family therapy literature, particularly the work of Bowen, provides its theoretical underpinnings. An integral part of family-of-origin presentations is the genogram, or visual depiction of a family tree. Many ethical issues arise from the use of family-of-origin work within the context of clinical training, including confidentiality, responsibility, informed consent, values, and the boundaries of the supervisory relationship.     

A feature analysis of stuttered phonemes

Stuttered and nonstuttered phonemes of 20 adult males were analyzed for distinctive feature patterns using the Chomsky-Halle system. The features (+ consonantal), (- voice), (+ continuant), and (- strident) occured significantly more often in stuttering than in nonstuttering instances. Results suggest that adult stuttering is most likely to occur when the primary sites of tension and discoordination are lingual and laryngeal and when the speaker must shift from (- voice) to (+ voice).
