Exogenous and endogenous attention orienting in autism spectrum disorders.

Fifteen children with high-functioning Autism Spectrum Disorder (ASD) and 15 children with typical development completed an attentional cuing task using peripheral cues (exogenous orienting) and central cues (endogenous orienting). Results showed that participants with ASD had impaired exogenous and intact endogenous orienting. The pattern of exogenous orienting was related to motor functioning. Individuals with ASD who had poor motor functioning displayed slowed exogenous orienting. However, individuals with ASD who had relatively good motor functioning showed typical levels of exogenous orienting when given a short time but decreased orienting when given a longer amount of time. These results suggest attention impairments in ASD may not be specific to social orienting and instead may represent a more general orienting impairment.     

The relationship between adolescent depression and a history of sexual abuse

The purpose of this study was to examine the occurrence of depression among adolescents attending family planning clinics, and to determine the relationship among depression, a history of sexual abuse, and other risk behaviors. The sample consisted of 279 minority females. Results of the study indicated that 40 adolescents (14.3%) scored at or above a raw score of 77 for depression based on the Reynolds Adolescent Depression Scale (RADS). This suggests that these adolescents should be identified for further evaluation. Results of the Stepwise Linear Regression indicated that a history of sexual abuse was the most potent factor in predicting depression. These findings highlight the importance of screening concurrently for depression and a history of sexual abuse in family planning and other healthcare settings.     

The Effect of Disruptions During Counseling on Recall of Genetic Risk Information: The Case of Cystic Fibrosis

Genetic counseling is a communication process with two main functions: information provision and supportive counseling. The information transmission function may be compromised by disruptions that occur during counseling. At least two mediators are possible: (a) disruptions may interfere with memory by creating distractions and divided attention during encoding or (b) disruptions may degrade the flow of interaction which requires that participants engage in conversation repair rather than the task at hand. This study examined both alternatives in a group of parents (N=20 families, 40 individual parents) whose infant had received a newborn screening for cystic fibrosis (CF). Upon arrival at the hospital, each parent completed a questionnaire designed to assess his or her knowledge of CF. Their interaction with the genetic counselor was videotaped and coded for the presence of disruptions. Six weeks after the counseling, parents again completed the knowledge measure. The data showed a direct negative effect for disruptions during counseling on memory for CF-related risk information six weeks later. Disruptions also produced the anticipated effect on conversation, but counter to expectations, interruptions of conversation flow was positively associated with knowledge at time 2.     

Functional neuroimaging of autobiographical memory

Functional neuroimaging studies of autobiographical memory have grown dramatically in recent years. These studies are important because they can investigate the neural correlates of processes that are difficult to study using laboratory stimuli, including: (i) complex constructive processes, (ii) recollective qualities of emotion and vividness, and (iii) remote memory retrieval. Constructing autobiographical memories involves search, monitoring and self-referential processes that are associated with activity in separable prefrontal regions. The contributions of emotion and vividness have been linked to the amygdala and visual cortex respectively. Finally, there is evidence that recent and remote autobiographical memories might activate the hippocampus equally, which has implications for memory-consolidation theories. The rapid development of innovative methods for eliciting personal memories in the scanner provides the opportunity to delve into the functional neuroanatomy of our personal past.     

Ethnic Diversity and the Use of Humor in Counseling: Appropriate or Inappropriate?

Humor can reflect the healthy release of feelings during the counseling process, the type of emotional release that leads to significant therapeutic gains. It can also be a disturbing distraction, possibly causing early termination, if used inappropriately. Counselors need to exert particular caution before attempting to apply humor in working with a client from a culture different from the counselor's. This article explores the available literature and offers contributions on the subject from 4 “ethnically diverse” perspectives. Finally, a general approach based on existential theory is presented along with 5 general conditions to ascertain the appropriate use of humor.     

Public Discourse: Creating the Conditions for Dialogue Concerning the Common Good in a Postmodern Heterogeneous Democracy

This paper offers a philosophical `history' of the nature of`public discourse' – a basic element of human rights. It beginswith Enlightenment views from Condorcet and Jefferson, turns to Dewey,and then to Habermas. Over a couple of centuries not only does thecentral character of discourse change but so too does the definition ofa public person.     

Variability in the initiation of articulatory movements in the speech of stutterers and normal speakers

This study was designed to investigate the differences between stutterers and normal speakers in phonatory and articulatory timing during the initiation of fluent utterances of monosyllabic words. Electromyographic recordings of four articulatory muscles and recordings of glottal vibrations were made of repetitive utterances of a series of monosyllabic words by 15 stutterers and 17 nonstutterers. These data were analyzed in terms of average interval times between voice onset and onset of EMG activity and between onset of EMG activity in each articulator and in terms of the intrasubject variability of these durational measures. Results showed that there were no significant differences between stutterers and nonstutterers in average interval times and that stutterers, in general, were significantly more variable in their speech onset timing. Findings are discussed in terms of recent hypotheses concerning the role of timing disturbances as the main source of speech disruption in stutterers.     

Effects of high and low dosages of methylphenidate in children with strong and sensitive nervous systems

This investigation was undertaken to explore the possible causes and consequences of the finding that attention- and learning-disordered children with sensitive (weak) nervous systems were titrated at higher dosages of methylphenidate than those with strong nervous systems. Pretreatment parent and teacher ratings of hyperkineticassociated behavior were no different for children typed as having strong or sensitive nervous systems or for those subsequently prescribed higher or lower dosages by a child psychiatrist “blind” to their type as well as condition (drug or placebo). However, those titrated at lower dosages, regardless of whether strong or sensitive, were rated as more improved than those given higher dosages. Pretreatment reaction time (RT) data suggested that sensitive types prescribed low dosages had less of a problem sustaining attention, and placebo RT data suggested that strong types titrated at low dosages had more of a problem sustaining attention. A contrast of placebo and drug RTs showed that strong types titrated at lower dosages improved more than strong types given higher dosages, whereas sensitive types given higher dosages improved more than sensitive types given lower dosages. The latter finding is thought to add support to the theory of Gray (1964), who suggested that, paradoxically, the weak nervous system needs a more intense stimulus than the strong to reach the concentration threshold.     

Sex role socialization and the development of achievement motivation in black preschool children

The effect of sex role socialization practices on the achievement motivation (Nach) of black preschool children of differing social-class levels was examined. A factor analysis of the Katz Sex Role Socialization Scale revealed several factors. These varied in their effect on two types of achievement motivation. In general, the hypothesis that nontraditional sex role training leads to higher achievement motivation for girls, and that traditional sex role training leads to higher achievement motivation for boys, received support. The importance of treating sex role socialization as multidimensional was stressed.This study is part of a doctoral dissertation by the senior author.
