Reducing sedentary behavior: the relationship between park area and the physical activity of youth

This study was designed to determine whether the characteristics of the neighborhood environment are related to the substitution of physical activity for sedentary behavior among youth. Fifty-eight 8- to 15-year-old youth were studied in a within-subjects crossover design with three phases: baseline, increased sedentary behavior, and decreased sedentary behavior. The relations between changes in physical activity and design, diversity, and density attributes of the neighborhood environment were determined using random coefficient models. Compared with girls, boys showed greater increases in physical activity when sedentary behaviors were reduced and greater decreases in physical activity when sedentary behaviors were increased. Greater access to parks was associated with greater physical activity when sedentary behaviors were reduced.     

The mythic function of narcissism

The paper makes some critical comments on the use Freud makes of myth and examines some of the inconsistencies and contradictions in his conceptualization of narcissism. Using some of the ideas of Bachelard and Hillman on the role of the imaginary, the authors theorize a function of myth that is independent of and not subordinated to the reality function. They suggest that narcissism must be seen not only in terms of individual history but that it has a mythic function; narcissism facilitates the creation of a relationship between the ego and the Self through the mediation of the imaginal world and through the prospective value of images.     

Detrimental therapist-client relationships--beyond thinking of "dual" or "multiple" roles: reflections on the 2001 AAMFT Code of Ethics

This article presents reflections on and a critique of the recent revision of the AAMFT Code of Ethics on the multiple relationship ethical standard. A brief historical overview of terminology and the debate surrounding "dual" and "multiple" relationship ethical rules in marriage and family therapy is provided. The term "exploitation" is also delimited. Ethical principles and a set of standards addressing "detrimental" versus "potentially beneficial" interactions are introduced, deriving from works in other mental health professions. The article recommends: (a) the terms "dual" and "multiple" relationships should be abandoned; (b) the ethical principles underlying the AAMFT Code of Ethics need to be examined; and (c) the debate on the topic of detrimental therapist-client interactions in marriage and family therapy needs to be revisited, especially in light of a "positive ethics."     

Using artificial life to teach evolutionary biology

This paper presents a pilot study on the use of artificial life software in an educational setting. Two groups of high school students received a standard lesson in evolutionary biology followed by a software session. The experimental group used the suite of artificial life software presented in this paper; the control group used a commercial multimedia hypertext. At the end of the software session both groups were asked to fill in a simple multiple-choice questionnaire testing the students knowledge of various aspects of evolutionary biology. The results show that the group using the artificial life software performed significantly better than the control group. We argue that the experimental group may learn more effectively because the artificial life makes it possible for students to perform experiments, a possibility not available to the control group.

Hierarchical representation of motives in goal setting

The authors developed a framework for thinking about motives in goal setting. The reasons for choosing a particular goal are represented in a hierarchical network of motives. To uncover context-specific motives and their interconnections, the authors propose a procedure based on the elicitation of justifications for one's goal. The authors applied the procedure to the motivation of volunteering to join the Italian Army by officers (N = 151) and 3 groups of enlisted soldiers (Garibaldi Brigade, N = 141; Folgore Brigade, N = 144; and volunteers in training, N = 150). The resulting idiographic motives and linkages between motives were validated by regressing attitudes, intentions to reenlist, and commitment toward the army on motives and linkages between motives. A heuristic nomothetic summary of goals, arranged in an interconnected hierarchy, was derived.     

Cerebellar ataxia: quantitative assessment and cybernetic interpretation

To assess neuromotor disorders clinicians often rely on rating scales. Unfortunately, these scales lack the sensitivity and accuracy needed to detect the small changes in motor coordination that reflect the clinical progression of the disease on the basis of which treatment programmes can be adjusted. As a contribution to this topic, the present paper proposes a straightforward kinematic and kinetic analysis of reaching movements of patients with cerebellar ataxia in conjunction with a cybernetic interpretation of the data. The aim of the approach is to capture key deficits in the underlying motor control processes. We suggest that cerebellar ataxia may be characterized by defective feedforward control.     

The Relevance of Multiculturalism for Aging

Though multiculturalists focus on race and minority status, issues of central importance to the aged, multiculturalism has not infiltrated the gerontology literature. However, since the so-called natural stages of life are cultural formations, each one a valuable creation, the topic of aging would certainly benefit from a connection to multiculturalism and its critique of the demands of assimilation.     

Aspects of verbal processing in relation to perceptual disembedding ability

In this study an attempt was made to extend the notion of disembedding from the perceptual to the verbal semantic domain. Fifty-two undergraduates were presented with the Group Embedded Figure Test (GEFT) and with seven verbal tasks. A Factor analysis made on test scores, as well as other factors, evidenced a factor that linked to gether the GEFT and one of the verbal tasks (Word groups). It is argued that both tasks require the restructuring of an organized context according to new given rules, and that disembedding is a mental operation which applies to both verbal and perceptual domains.     

Autobiographical recall training in elderly adults with subjective memory complaint: a pilot study

Subjective memory complaint is a self-reported memory impairment which affects elderly people. This problem does not interfere with daily living activities but could decrease quality of life. This study's purpose was to verify whether a specific, newly developed, autobiographical recall training could modify self-perception of memory of subjects with subjective memory complaint. Seven elderly subjects (4 women and 3 men; mean age 65.5 yr., SD=11) with such complaint, evidenced through a specific questionnaire, attended the training course and were prospectively assessed on standard neuropsychological tests, depressive symptomatology, and self-perception of memory. Self-perception of memory, as assessed by scores on a formalized questionnaire, improved significantly after the training, while depressive symptoms did not change. Neuropsychological performances were normal before and after the training, but a statistically significant improvement was observed only on the phonological fluency test. Thus the present pilot study suggested that the training may be effective in improving self-perception of memory and metamnestic capacity in elderly people with subjective memory complaints but not in changing subjects' depressive symptoms. This requires replication of this work with a much larger sample so statistical power is adequate.
