Disability, Connectivity and Transgressing the Autonomous Body

This paper explores the interconnectedness of persons with disabilities, technologies and the environment by problematizing Western notions of the independent, autonomous subject. Drawing from Deleuze and Guattari's reconfiguration of the static subject as active becoming, prevailing discourses valorizing independence are critiqued as contributing to the marginalization of bodies marked as disabled. Three examples of disability "dependencies"-man-dog, man-machine, and woman-woman connectivities-are used to illustrate that subjectivity is partial and transitory. Disability connectivity thus serves a signpost for an expanded understanding of subjectivity and suggests a radically altered ethics that is no longer premised on individual rights.     

The effect of perceived parental involvement and the use of growth-fostering relationships on self-concept in adolescents participating in gear up

Adolescence is marked by physical, cognitive, and social changes which affect how individuals perceive themselves. However, individuals do integrate their perceptions with those of significant others. Adolescents' self-concept is influenced by their relationships with family, peers, mentors, and community groups. In this study, the characteristics of these relationships are examined as well as the perception of parental involvement. The effect of perceived parental involvement and the use of growth-fostering relationships on self-concept was examined using 78 adolescents who were participating in GEAR UP (Gaining Early Awareness of Readiness for Undergraduate Programs). Results support the influence of family, peers, mentors, and involvement in community groups on adolescent self-concept.     

Tactile spatial sensitivity and anisotropy

A gap detection task was examined for its usefulness as a measure of tactile spatial sensitivity and as a measure of anisotropy. In Experiment 1, sensitivity was measured with a gap detection task both with and without a latex glove at three locations on the hand: the fingerpad, fingerbase, and palm. Results showed that sensitivity varied as a function of location and was correlated with changes in the density of innervation of the primary afferent fibers. In accord with other measures of spatial sensitivity, the glove had a moderate effect on sensitivity in the gap detection task. The results both with and without the glove were more similar to those obtained using another measure of spatial sensitivity, the grating orientation task, than to those obtained using the smooth-grooved task, which is considered an intensive measure. In Experiments 2-4, anisotropy was examined using the gap detection and grating orientation tasks, as well as the smooth-grooved task. Locations on the index finger, palm, and arm were tested. Results indicated that anisotropy was revealed only by tasks that relied on spatial cues. The differences between spatial sensitivity measured in the proximal-distal orientation as compared with the lateral-medial orientation varied by location and were as much as 2.35/1. The results are discussed in terms of what they may reveal about the underlying mechanisms responsible for tactile anisotropy.     

Three-month-olds, but not newborns, prefer own-race faces

Adults are sensitive to the physical differences that define ethnic groups. However, the age at which we become sensitive to ethnic differences is currently unclear. Our study aimed to clarify this by testing newborns and young infants for sensitivity to ethnicity using a visual preference (VP) paradigm. While newborn infants demonstrated no spontaneous preference for faces from either their own- or other-ethnic groups, 3-month-old infants demonstrated a significant preference for faces from their own-ethnic group. These results suggest that preferential selectivity based on ethnic differences is not present in the first days of life, but is learned within the first 3 months of life. The findings imply that adults' perceptions of ethnic differences are learned and derived from differences in exposure to own- versus other-race faces during early development.     

On the least-squares orthogonalization of an oblique transformation

After proving a special case of a theorem stated by Eckart and Young, namely, that an oblique transformationG is the product of two different orthogonal transformations and an intervening diagonal, this note shows that the best fitting orthogonal approximation toG is obtained simply by replacing the intervening diagonal by the identity matrix. This result is shown to be identical with two earlier orthogonalizing procedures whenG is of full rank. A multiplicity of solutions is shown for the case of a singularG.I am grateful to J. J. Mellinger for pointing out a flaw in a previous version of this paper.Opinions expressed herein are those of the author, not necessarily those of the Army.     

Nonsmokers' Attributions for the Outcomes of Smokers: Some Potential Consequences of the Stigmatization of Smokers1

The current research examines intergroup attributional biases made by nonsmokers for the outcomes of smokers. Nonsmokers were asked to make attributions for either the success or failure of either an in-group member (a nonsmoker) or an out-group member (a smoker). Overall, subjects attributed the preponderance of cause for the outcomes to external or unstable (approximately 80%) rather than internal (approximately 20%) factors. However, results confirmed the expected in-group protective and in-group enhancing attributions on the part of nonsmokers. Specifically, nonsmokers attributed a significantly higher proportion of success to external factors and a lower proportion of success to internal factors when the target was a smoker compared to when the target was a nonsmoker. The implications of these results for smokers and smoking policy are discussed.     

The relationship between the frequency and the processing complexity of linguistic structure

In this paper the relative frequencies of the possible resolutions of ambiguities involving noun phrase attachment sites are compared to the results of off-line psycholinguistic measurements of syntactic complexity. A lack of correlation between the two is observed. It is therefore argued that the comprehension system is distinct from what is driving the frequencies in the corpora. A production heuristic separate from the comprehension system is proposed to account for the observed frequencies.We would like to thank Susanne Tunstall for providing linguistic judgments in the corpus analyses reported in Sec. 3.3.

Semantic differential techniques in the identification of individuals assessment of health state: A case study of a patient within a homoeopathic regime

A retrospective study of patients (n = 166) on a wheat free diet showed improvements in patients diagnosed as wheat sensitive over patients not so diagnosed (p = 0.05). Clinical history indicated marked differences between these groups in perceptions of health. Individual follow up studies indicated that a Semantic Differential grid, derived from a patient group (n = 20) through semantic and repertory techniques, was a good indicator of these clinical perceptions. The results of one patient in this group are presented and show the typical results obtained by principal component analysis of the semantic grid administered over two visits to the hospital. Patient perception of well being shown by the grid analysis was confirmed by clinical history. The implications of this semantic approach for patient self reporting and clinical counselling are discussed. Larger scale studies are currently being planned on wheat sensitivity and associated psychological effects, using a variety of psychological measures, in a large range of patient groups (including Myalgic Encephalomyelitis, Multiple Sclerosis and Rheumatoid Arthritis).
