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.  相似文献

The purpose of this study was (a) to evaluate the ability of the existing validity indices of the Minnesota Multiphasic Personality Inventory (MMPI-2) in detecting faking. bad and faking-good profiles, (b) to differentiate between two strategies for faking-good (denial and claiming extreme virtue), (c) to determine the effectiveness of the new MMPI-2 validity scale, the S scale, in detecting people's tendency to present themselves in a superlative manner, and (d) to explore the response strategy under conditions in which individuals we known to be distorting their responses to the MMPI-2 Participants were 167 undergraduate, college students who were administered the test under different conditions, and 50 hospitalized, psychiatric patients. Mean profile configurations and optimal cutoff scores obtained in this study were similar to those reported in previous studies. Accurate identification of faked profiles was achieved. The new S scale and its subscales, especially S2 (Serenity), S3 (Contentment With Life), and S5 (Denial of Moral Flaws), showed particular promise in detecting faking-good (denial and claiming extreme virtue) profiles, Participant's debriefing provided valuable information about the participants' understanding of the instructions and their deception strategies. The attempts to differentiate between two strategies for faking-good, denial and claiming extreme virtue, were not successful, However, these results should not be taken to indicate that the particular strategies assessed in this study cannot be differentiated. Methodological issues reviewed suggest that further research might yield more understanding of the nature of any deception efforts made by respondents. In addition, future, research is needed to discover if the findings from this study generalize to other clinical settings and populations.  相似文献

Relationships among children's affective expression in fantasy play, interpersonal themes in projective stories, and concurrent interpersonal behaviors were investigated in 49 children. Participants completed a play task, a projective storytelling task, and a brief IQ measure. Peer and teacher ratings provided measures of interpersonal functioning. Results found that access to and comfort with affect is related to the ability to think in interpersonal ways. Neither affective expression in play nor interpersonal themes in projective stories were related to actual interpersonal behavior.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献
