Social stimulation and joint attention in young autistic children

The present study was designed to examine the effects of social stimulation on the joint attention behavior of 20 autistic children under 6 years of age, 20 receptive language-matched Down syndrome children, and 20 receptive language matched-normally-developing infants. Children's social and non-social engagement states were measured during two experimental play sessions and during free play with parent. For all groups, joint attention was increased when adult play behavior closely followed and was contingent on the behavior of the children; however, the autistic children were significantly less responsive to the experimental manipulation than control subjects. In contrast, the autistic children were no less responsive in terms of other forms of social engagement. Results are interpreted as supporting a model of joint attention deficits in autism that involves factors inherent to the disorder in transaction with social context.     

The relationship of marital status,spouse’s career status,and gender to salary level

The relationship of marital status, spouse’s career status, and gender to salary was examined from five different theoretical perspectives for a sample of managers and professionals in one large organization. Results showed that married individuals whose spouses did not have careers earned more than anyone except those who were divorced, controlling for age, education, type of position, job location, organizational tenure, and job tenure. Results also showed that individuals who had never been married earned the least, women earned less than men, and men with children at home earned more than men with no children at home. These findings are discussed in terms of the different theoretical perspectives, within a changing social content.     

Parent training for attention-deficit hyperactivity disorder: Its impact on parent functioning

This study examined changes in parent functioning resulting from parental participation in a behavioral parent training (PT) program specifically designed for school-aged children with attention-deficit hyperactivity disorder (ADHD). Relative to wait list controls, subjects who completed the nine-session PT program showed significant posttreatment gains in both child and parent functioning, which were maintained 2 months after treatment. In particular, there were PT-induced reductions in parenting stress and increases in parenting self-esteem, which accompanied parent-reported improvements in the overall severity of their child's ADHD symptoms. In addition to their statistical importance, these findings are discussed in terms of their clinical significance, utilizing methods developed by Jacobson and Truax (1991).This project was supported in part through BRSG grant S07RR05712-19 awarded to Arthur D. Anastopoulos by the Biomedical Research Support Program, Division of Research Resources, National Institutes of Health.     

Changes in Fear of AIDS and Homophobia in a University Population

A survey measuring attitudes toward fear of AIDS and homophobia, taken in the fall of 1985, was repeated in the fall of 1989 on the same university population. The results indicated that whereas fear of AIDS decreased, the degree of homophobia remained essentially unchanged. In addition, although respondents were much more knowledgeable about AIDS in 1989 than in 1985, there was no evidence of any change in the relatively high correlation between the fear of AIDS and homophobia.     

FROM DNA TO DEAN

Abstract. In this broadly intellectual autobiographical essay, Arthur Peacocke describes how his educational background at Oxford led him eventually to physicochemical studies on DNA and other biological macromolecules and how biological complexity and the general problems it evokes have remained a recurring theme in his thought. He also describes how, although coming from a relatively non ecclesiastical background, this interest has nevertheless been intertwined with the larger questions to which the Christian faith seeks to respond. He outlines how he has been able to reconcile these two strands in his existence-even to becoming a priest-scientist and eventually the Dean of chapel of a Cambridge college. He reflects on the trends in the relation of religion and science over the last four decades and points to some hopeful developments in the relation between the two communities-and to some unanswered questions.

Regional cerebral blood flow patterns during verbal and nonverbal auditory activation

Current views of the relationship between audition and cerebral function suggest that increases in regional cerebral blood flow (rCBF) would occur in the superior, mid, and posterior portions of the temporal lobes, and that these changes would be more lateralized to the left hemisphere for a verbal than a nonverbal auditory task. We measured rCBF using the xenon inhalation technique in a group of healthy subjects during three conditions: (1) resting baseline, (2) auditory verbal activation (listening for word meaning), and (3) auditory nonverbal activation (listening for reduction of intensity in a series of noise bursts). Both verbal and nonverbal conditions produced highly significant increases in rCBF over the left posterior Sylvian region with a trend for verbal activation to evoke a wider area of flow increase than the nonverbal task.     

Information in speech: observations on the perception of [s]-stop clusters

A series of experiments is reported that investigated the pattern of acoustic information specifying place and manner of stop consonants in medial position after [s]. In both production and perception, information for stop place includes the spectrum of the fricative at offset, the duration of the silent closure interval, the spectral relationship between the frequency of the stop release burst and the following periodically excited formants, and the spectral and temporal characteristics of the first formant transition. Similarly, the information for stop manner includes the duration of silent closure, the frequency of the first formant at the release, the magnitude of the first formant transition, and the proximity of the second and third formants at release. A relationship was shown to exist in perception between the spectral characteristics of the first formant and the duration of the silent closure required to hear a stop. This appears to reciprocate the covariation of these parameters in production across different places of articulation and different vocalic contexts. The existence of perceptual sensitivity to a wide range of the acoustic consequences of production questions the efficacy of accounts of speech perception in terms of the fractionation of the signal into elemental acoustic cues, which are then integrated to yield a phonetic percept. It is argued that it is inappropriate to ascribe a psychological status to cues whose only reality is their operational role as physical parameters whose manipulation can change the phenotic interpretation of a signal. It is suggested that the metric of the information for phonetic perception cannot be that of the cues; rather, a metric should be sought in which acoustic and articulatory dynamics are isomorphic.
