Nearest neighbor analysis of point processes: Simulations and evaluations

Tversky, Rinott, and Newman (Journal of Mathematical Psychology, 1983, 27, 000) examine the asymptotic behavior of a measure of the centrality of the nearest neighbor relation. The applicability of their conclusions when the number of dimensions (d) and the number of points (n) take on the small-to-moderate values commonly encountered in the analysis of proximity data is investigated. The results suggest that convergence is fast when n is large relative to d and slow when d is large relative to n.     

The use of children's drawings in multiple family group therapy

This paper describes the advantages, difficulties and techniques of including young children in multiple family group therapy (MFGT). Multiple family group therapy consists of weekly sessions where three or more families meet conjointly with a therapist or cotherapists. Clinical vignettes demonstrate how to use children's drawings with parents to improve family communication. The efficiency of MFGT is compared to family therapy or individual therapy. The effective use of this modality with some children under 10 years is discussed.This research was supported in part by Alcohol, Drug Abuse, and Mental Health Administration Psychiatry Education Branch Grant MH 13882 from the National Institute of Mental Health.     

Perceptibility of schematic face stimuli: Evidence for a perceptual Gestalt

The perceptibility of face, scrambled face, and single-feature stimuli was investigated in three experiments. Stimuli were presented tachistoscopically, followed by a visual noise mask and a forced-choice test of one of three features (eyes, nose, and mouth). In Experiment I, two processing strategies which have been proposed for word perception (involving expectancy and redundancy) were investigated for the stimuli employed here. In Experiments II and III, experimentally induced familiarity was studied for its effect on recognition and perception, and an immediate and delayed perceptual test was employed. Across all three experiments, perception of single-feature and face stimuli were consistently superior to scrambled faces; in Experiment III, differences between single features and faces were eliminated. The effects of perceptual expectancy, internal feature redundancy, familiarity, guessing biases, etc., were shown to be insufficient to account for the superiority of face to scrambled face stimuli. It was argued that the perceptibility of nonredundant features are enhanced when those features are aligned in a well-defined form class. The view that familiarity operates directly on recognitive processes but indirectly on perceptual ones was discussed.     

A simple IC pulse-pair stimulator

The present paper describes a simple and relatively inexpensive brain stimulator circuit for generating trains of conditioning (C) and test (T) pulse pairs for refractory period and excitability cycle analyses. G and T outputs are constant-current monophasic cathodal pulses of adjustable frequency, duration, amplitude, and delay. C and T pulses can be controlled manually or through logic programming and can be fed out the same or separate channels. The stimulator can be operated on either ac or dc supplies and, when battery operated, features a high degree of stimulus isolation.     

Prayers, spiritual support, and positive attitudes in coping with the September 11 national crisis

This study was designed to help fill gaps in faith-related and positive psychology research. Psychologists have called for precise assessment of effective faith factors inherent within spiritual experiences that may explain their beneficial effects. Positive psychologists suggest the need to examine social and faith-related origins of optimism. Based on previous research, we redefined spiritual support and developed a new assessment. The study is a survey of 453 graduate and undergraduate students 3 months after the September 11, 2001, terrorist attacks. The results showed that participants, who believed in diverse spiritual entities, used various types of prayer for coping. A structural equation model showed that a linkage of spiritual support and positive attitudes mediated the effect of faith-based and secular factors on post-September 11 distress. Higher levels of initial negative emotional response were associated with the use of prayer for coping, which was, in turn, related to less distress through the pathway of the above linkage.     

Moral absolutism and abortion: Alan Donagan on the hysterectomy and craniotomy cases

Reynolds argues that the nonconsequentialist moral theory proposed by Alan Donagan in his book The Theory of Morality (University of Chicago Press; 1977) does not resolve the cases in which craniotomy or removal of a cancerous uterus appears necessary to save the life of a pregnant woman. Donagan's absolute prohibition against the murder of the innocent and his rejection of the principle of double effect have led him to view the fetus as a pursuer or assailant or to assert the theory of proleptic agreement--that in risk taking ventures the parties may agree that killing one person to save the lives of the others will be accepted. Reynolds holds these arguments to be inapplicable in therapeutic abortions involving craniotomy or hysterectomy and concludes that Donagan's absolutist theory must be reexamined.

The Influence of a Community-Based Service-Learning Experience on the Development of Occupational Therapy Students' Feelings of Civic Responsibility

This qualitative study examined the influence of service-learning on the development of Students' feelings of civic responsibility while involved with a community-based organization. Occupational therapy students involved in a semester-long service-learning experience maintained weekly reflective journals. Six such reflective journals were randomly selected for analysis. Findings revealed that while engaged in service-learning the six participants voiced themes of increased self-awareness, awareness of homeless individuals as persons, awareness of social issues, and professional self-efficacy. These developing competencies are associated with the skills required for health care professionals to participate in civic engagement and client advocacy.
