Binocular cues in the perception of distance of a point source of light

The ability to make egocentric distance estimates of a single point source of light, seen in darkness and without the cues of changing size and luminance, was investigated in sixteen observers. The attenuation required to maintain constant luminance, when the target was viewed from different distances, was shown to follow the inverse square law providing the angle subtended by the light was less than 20 s arc. Distance changes were also simulated by means of a split mirror which produced vergence cues, or by test lenses to provide accommodation cues. Over the range 0.5 to 9.2 m distance estimates were surprisingly accurate, although there was some overestimation of near and underestimation of far distances. Most observers made good judgements when only convergence cues were varied, whereas no observers made consistently good judgements when only accommodation cues were varied. The difficulties are discussed in terms of the accommodation-convergence link. When distance was simulated by changing convergence and accommodation cues, estimates were not as good as when real distance was changed. Since good estimates were made with brief target exposures, these judgements were not based on subsequent convergence or accommodation changes. It is suggested that the metric or reference against which the apparently absolute judgements were made was the efferent demand signal associated with a 'resting' position of convergence in darkness.     

Biofeedback, cognitive training and relaxation techniques as multimodal adjunct therapy for hospitalized adolescents: a pilot study

Modifications and adjuncts to traditional therapy techniques appear to be necessary for successfully treating hospitalized adolescents with impaired social and verbal skills, and a history of acting-out behavior. Modified therapy groups were combined with a structured biofeedback and cognitive training program to help these adolescents control anger and modify their behavior. Used in conjunction with training and practice in relaxation techniques, this multimodal treatment approach appeared to be helpful in both reducing incidents of acting out on residential units, and in reaching individualized therapeutic goals. The present paper describes use of this multimodal approach within selected residential settings, and outlines the structured materials developed by the authors.     

Measuring the activity of severely and profoundly mentally-handicapped adults in ordinary housing

Earlier work on the quality of care in settings for severely and profoundly mentally-handicapped adults raised the question whether any useful purpose is served by promoting the extensive use of simple recreational materials to occupy people. Data were collected by direct observation on the activity of 6 adults living in a staffed house organized to promote engagement in household activities. Observations were taken over 5 weekdays from 07.00 to 10.00 and 15.00 to 23.00hr. The results showed that Ss spent between 22 and 67% of available time in purposeful activity. Between 27 and 65% of purposeful activity was engagement in domestic or housework tasks. Even the most handicapped people spent more time engaged in housework than in leisure and recreational tasks. The implications of these data are commented on and measurement issues which arise in ordinary housing as opposed to institutional settings are discussed.     

Becoming No-Thing: Eckhart and Hegel on Identity and Difference

Abstract: My goal in this paper is to draw productively on Meister Eckhart's concept of the ‘no-thing’ in order to illuminate Hegel's ontotheological account of both human and divine kenosis. I advance the view that just as divine kenosis is understood as the outpouring of the divine which includes the death of Christ in its economic activity, human kenosis also requires an engagement with death, namely, a spiritual death to the finite. It is via this species of death which is a becoming ‘no-thing’ that the reconciliation between the human and the divine is disclosed as a unity that relies on the shared identity of the divine and the human while simultaneously respecting the integrity of both. Indeed, it is in and through their parallel activity of kenosis that finite and infinite being achieve their respective transcendence by necessarily engaging with the being of the other. Hence, Hegel's ontotheological work is not reducible to sheer immanentism as some scholars suggest, but instead upholds the genuine transcendence of the divine.     

Gender differences in personality: Biological and/or psychological?

The results of three empirical studies are reported in which the hypothesis is tested that differences in personality variables between the morphophenotype sexes can be explained by psychological sex-role orientation variables. Furthermore, it was expected that normative sex-role orientations (measured with the SRO-S and the AWS-S Scales) and gender-related self-concepts (femininity, masculinity, and androgyny measured with a modified BSRI) explain more variance in personality variables than morphophenotype sex. Besides these sex-role orientation variables, test and questionnaire data on verbal fluency, spatial reasoning, self-concept, anxiety, and aggressiveness were obtained in Study I from 50 young adults and their same-sex parents; in Study II, data on verbal fluency, spatial reasoning, self-concept, anxiety, and neuroticism were obtained from 120 university students; and in Study III, data on anxiety, locus of control, and Machiavellianism were obtained from 226 university students. The results confirm both hypotheses for the two aspects of intelligence studied, domain-specific self-concepts, different aspects of anxiety and aggressiveness, neuroticism, powerful others' externality in locus of control, and Machiavellianism. For all these personality variables the effect sizes of the psychological gender variables were larger than those of morphophenotype sex and reached medium to large values.     

Structured role assignment and other techniques for facilitating process in adolescent psychotherapy groups

The application of various types of techniques for structuring the interchange and feedback process in adolescent psychotherapy groups is described. Techniques include random assignment of "roles" for each member during sessions, "parent hot seat" exercises, group goal booklets, and negotiation exercises. These have proved helpful in ensuring effective group participation, providing practice in social skills and verbalization of feelings, and in the development of other specific mastery skills.
