An alternative assessment of children's comprehension of relative clauses

Methodological difficulties are identified in the assessment of children's comprehension of relative clauses (RCs) by means of the standard acting-out procedure. An alternative experimental task is proposed which attempts to minimize these difficulties while exploring the advantages of the acting-out technique. An experiment is reported in which Portuguese-speaking 3- to 6-year olds were tested by means of this alternative task. The results show children being affected by both the position and the focus of the RC in the same way adults have been reported to be and an error analysis suggests that most of children's difficulties can be ascribed to memory overload while RCs are processed as noun modifier sentences. These results contradict the view that there are developmental differences with regard to the way sentences with RCs are parsed and that processing load induces errors particularly manifested in right-branching subject focus sentences. Developmental changes taking place between the ages of 3 and 6 are considered and questions are raised concerning development from the age of 5.The research reported here was carried out while the author read for the PhD degree at the University of London.

Group therapists and AIDS groups: An exploration of traumatic stress reactions

As the AIDS epidemic continues unabated, there is growing clinical evidence that the catastrophic nature of this disease is creating a second category of trauma casualties. They are the health care practitioners who witness the narratives of those who are living with and dying from AIDS. This article examines how multiple AIDS-related deaths of group members exert a traumatizing effect on group therapists, creating vicarious traumatization. Vignettes are presented that illustrate reactions associated with traumatic stress, including death images, survivors' guilt, psychic numbing, suspicion of counterfeit nurturance, and struggle for meaning. Possible therapeutic interventions for group therapists coping with multiple deaths are also explored.The author wishes to acknowledge the endeavors of the volunteer group therapists and the Clinical Group Services staff of the Gay Men's Health Crisis of New York City, who provide group therapy to over 900 clients a week. This article is written in admiration of their extraordinary effort and dedication.     

Beyond belief bias: Reasoning from conceptual structures by mental models manipulation

Mental models constitute an alternative to the rule-based systems in the explanation of human reasoning (Johnson-Laird, 1983). In this paper, we claim that the concept of believability generally used to categorize content and context effects is of little use within a semantic theory. Thus, we propose the use of categories that are directly extracted from subjective relations among concepts within the reasoning problem. We demonstrate that manipulations based on this kind of categorization produce predictable patterns of responses in reasoning problems. We present two experiments to test our predictions, using conditional and syllogistic reasoning problems, and in both cases, we demonstrate the influence of conceptual knowledge not only in natural contexts, but also in experimentally created artificial contexts.
