Longitudinal Development of the Automatic Postural Response in Infants

In this longitudinal study, the development of automatic postural responses elicited during stance following perturbation of the support surface was investigated. Infants (N = 9) unable to stand without support were tested initially: follow-up tests were performed until the infants were able to stand and walk independently. Surface electromyographic recordings of leg and trunk muscle activity following a postural perturbation induced by a forward or backward translation of the support surface were made for each infant. Muscle onset latencies following the perturbation and the proportion of trials in which muscle activity was recorded were determined. First, infants activated appropriate muscles either in isolation or in pairs and then combined these muscles into functional synergies. Although activation of all three postural muscles was recorded in infants before they were able to stand and walk independently, the three-muscle response was not consistent in the youngest children. The proportion of trials eliciting muscle activity continued to increase (p <.O5) after infants began to walk independently, with postural muscle activity recorded in virtually every trial by late independent walking. Thus. the automatic postural response elicited during stance was shown to begin with activity in single or paired muscles, followed by activation of the postural muscles in functional synergies. These data illustrate the progressive development of an effective sensory-motor organization.     

Models of madness: Science and soul

The historical interplay between psychiatry and religion is placed in a contemporary context here. In their zeal to embrace new discoveries and technologies in neurophysiology, modern psychiatrists are losing sight of spiritual and cultural dimensions. From a biological perspective, there is confusion about what constitutes a cause, a concomitant, or a consequence of mental illness. Computer metaphors are being used to explain mental illness. This article examines such trends and questions whether, in the decade of the brain, psychiatry is in danger of losing its soul.     

Cognitive-behavioral treatment for professional sexual misconduct among the clergy

Inappropriate sexual behavior by professionals has been reported in increasing numbers. This article focuses on the cognitive-behavioral treatment of clergy who have acted out sexually. Case studies are used to identify the various issues and facets of treatment. The article concludes with a program designed to return previously offending clergy to active roles within their denominations is described.     

AN AMERICAN NATURALIST ACCOUNT OF CULTURE

The basic tenets of “classical” naturalism (exemplified in the work of Mead, Buchler, and Randall, among others) are delineated and distinguished from other versions of naturalism. Classical naturalism is also distinguished from reductive materialism and idealism. Nature is asserted to be indefinitely plural and not amenable to monistic or dualistic categorial schemes; that is, the principle of “ontological parity” is maintained. The method of inquiry of naturalism is outlined, along with the notion of truth as perspectivally objective. The metaphysical hypotheses are then used to examine culture. Culture is found to be the specific environment of human being, arising out of, but irreducible to, other natural processes. Culture is described as the cumulative gestures of the human social organism as it discovers and creates itself in mutual constitution with other natural processes and products.     

Decompositions and biplots in three-way correspondence analysis

In this paper correspondence analysis for three-way contingency tables is presented using three-way generalisations of the singular value decomposition. It is shown that in combination with Lancaster's (1951) additive decomposition of interactions in three-way tables, a detailed analysis is possible of the deviations from independence. Finally, biplots are shown to produce powerful graphical representations of the results from three-way correspondence analyses. An example from child development is used to illustrate the theoretical developments.     

Partial matching in the Moses illusion: Response bias not sensitivity

Previous research has demonstrated that people have enormous difficulty in detecting distortions in such questions as, “How many animals of each kind did Moses take in the Ark?” Reder and Kusbit (1991) argued that the locus of the effect must be the existence of a partial-match process. Other research has suggested that this partial-match process operates at the word level and that, with adequate focus on the relevant word, the Moses illusion is greatly diminished. The present experimental results argue that those conclusions were based on a shift in response criterion with no concomitant change in ability to detect distortions. Furthermore, the data suggest that the matching process operates below the word level, at the level of distinctive features.     

Attentional Focus of Students with Hyperactivity During a Word-Search Task

Mirrors have been used to focus attention to aspects of the self (e.g., to known strategies, standards). We hypothesized that this could be important for students with hyperactivity/inattention, who typically direct attention outward to external novelty. In this study, we administered a partially solvable word puzzle to 43 middle school students, with and without hyperactivity/inattention, in the presence and absence of a mirror, counterbalanced for condition and form order. Differences between students with hyperactivity/inattention and comparisons in accuracy were found only in the no mirror condition. Furthermore, the beneficial effect of the mirror for children with hyperactivity/inattention was most pronounced for those who looked at the mirror. Findings were interpreted in terms of their potential to remedy the production deficits of these children.
