Prosodic phrasing is central to language comprehension

Words, like musical notes, are grouped together into phrases by their rhythmic and durational properties as well as their tonal pitch. This 'prosodic phrasing' affects the understanding of sentences. Many processing studies of prosody have investigated sentences with a single, grammatically required prosodic boundary, which might be interpreted strictly locally, as a signal to end the current syntactic unit. Recent results suggest, however, that the global pattern of prosodic phrasing is what matters in sentence comprehension, not just the occurrence or size of a single local boundary. In this article we claim that the impact of prosodic boundaries depends on the other prosodic choices a speaker has made. We speculate that prosody serves to hold distinct linguistic representations together in memory.     

Less is more: executive function and symbolic representation in preschool children

Executive function is recognized as a critical component of children's cognitive and social development. In two studies, a measure of executive function that had been used in research with chimpanzees was adapted for preschoolers. On this task, called Less Is More, children must point to a smaller reward (two candies) to receive a larger reward (five candies). In Study 1 (N= 101), performance was significantly related to age (3 vs. 4), verbal ability, and established measures of executive function. In Study 2 (N= 128), symbolic representations substituted for real candies in this task. Three-year-olds' performance improved significantly as a function of symbolic distancing. This research has implications for the role of symbol systems in the development of executive control over thought and action.     

Use of the Personality Assessment Inventory in Assessment of Posttraumatic Stress Disorder in Women

This study investigated the utility of the Personality Assessment Inventory (PAI) for the assessment of posttraumatic stress disorder (PTSD). Participants were 55 community-residing adult women who were administered a comprehensive battery that included the PAI and the Clinician-Administered PTSD Scale (CAPS). Participants were classified as either PTSD or non-PTSD based on the CAPS, and PAI profiles were compared between the two groups. Significant group differences were found for seven PAI clinical scales (Anxiety, Depression, Anxiety-Related Disorders, Somatic Complaints, Paranoia, Borderline Features, and Schizophrenia), one validity scale (Negative Impression), and two treatment scales (Nonsupport and Treatment Rejection). When all PAI scales and component subscales are considered, the largest group differences were found for the physiological subscale of the Depression scale (DEP-P) and the Traumatic Stress subscale of the Anxiety-Related Disorders scale (ARD-T). ARD-T and DEP-P also demonstrated excellent diagnostic utility. Finally, correlations between PAI scales and four CAPS symptom clusters provided additional validity evidence, in particular supporting a distinction between effortful avoidance and numbing. Taken together, these results support the use of the PAI in the assessment of PTSD.This study was the basis of a Masters thesis for Meghan McDevitt-Murphy. Portions of this study were presented at the annual meeting of the Association for Advancement of Behavior Therapy, November 2000.     

Temperament, relationships, and young children's receptive cooperation with their parents

The authors studied receptive cooperation--a willing, eager stance toward parents--in 15-month-old children (N = 101) in broadly ranging contexts. Children's anger proneness and parents' responsiveness (both observed at 7 months) and children's attachment security (assessed in Strange Situation at 15 months) were examined as predictors of children's receptive cooperation at 15 months. In mother-child dyads, secure attachment was strongly associated with children's higher receptive cooperation. Maternal responsiveness in infancy also promoted children's future receptive cooperation, but its impact was moderated by child anger: Responsiveness had a positive effect for children who as infants were highly anger prone. In father-child dyads, the negative effect of anger proneness on receptive cooperation with father was significantly amplified for insecure children. Mother's responsiveness and child's secure attachment to the mother promoted child receptive cooperation with the father, but there were no similar effects for fathers.     

Etiologic connections among substance dependence,antisocial behavior,and personality: modeling the externalizing spectrum

A hierarchical biometric model is presented of the origins of comorbidity among substance dependence, antisocial behavior, and a disinhibited personality style. The model posits a spectrum of personality and psychopathology, united by an externalizing factor linked to each phenotype within the spectrum, as well as specific factors that account for distinctions among phenotypes within the spectrum. This model fit self-report and mother-report data from 1,048 male and female 17-year-old twins. The variance of the externalizing factor was mostly genetic, but both genetic and environmental factors accounted for distinctions among phenotypes within the spectrum. These results reconcile evidence for general and specific causal factors within the externalizing spectrum and offer the externalizing factor as a novel target for future research.     

Inhibition of attended processing during saccadic eye movements

People are unable to perform some, but not all, cognitive tasks while moving their eyes. A possible common denominator among disrupted processes is the use of attention. The present research proposes and tests an attentional suppression hypothesis to evaluate this claim. This hypothesis states that because attention is obligatorily allocated to a to-be-fixated location prior to the onset of a saccade, during saccadic events attentional resources are unavailable to direct processing associated with higher order cognitive tasks. Subjects were engaged in a task that combined saccades and shifts of attention across global and local levels of hierarchical figures. When the eyes did not move, this shift took place between stimulus presentations. When saccades intervened between the stimuli, the global-local shifts of attention were interrupted, suggesting that saccades suppress cognitive processes requiring attention.     

Ukrainian Application of the Children's Somatization Inventory: Psychometric Properties and Associations With Internalizing Symptoms

This paper examines the psychometric properties of the Children's Somatization Inventory (CSI) in 600 10–12-year old children in Kyiv, Ukraine, replicating and extending the original findings from a sample in Nashville, Tennessee (J. Garber et al. 1991). The Kyiv children had significantly lower CSI total scores and reported significantly fewer symptoms than the American children. The Kyiv mothers, however, reported significantly more somatization symptoms in their children than did the American mothers. A factor analysis of the children's data yielded four similar factors encompassing pseudoneurologic, cardiovascular, gastrointestinal, and pain/weakness symptoms. Consistent with the findings from the Nashville study, the CSI was significantly related to the children's self-reports of health and depressive and anxiety symptoms and to maternal reports of child depression and anxiety symptoms. In addition, although more children with the highest CSI scores (25+) reported various illness experiences than those with 0–1 symptoms, no differences were found in the school absentee records. Thus, the results were congruent with the findings of the Nashville study, indicating that the CSI reliably measured somatization in this Ukrainian sample.     

Entering Politics: General Self‐Efficacy and Voting Behavior Among Young People

Political science traditionally conceptualizes efficacy only in relation to politics and government. In this article, we look beyond political efficacy and examine the effect of general self‐efficacy on young adults' voting behavior. General self‐efficacy, an individual's estimation of capacity to operate successfully across a variety of domains, is often important to the behavioral decisions of individuals entering a new domain of activity. With data from the Children of the National Longitudinal Study of Youth, we examine the effect of general self‐efficacy on voting behavior among young, first‐time voters. We find that general self‐efficacy has a positive effect on voter turnout, and this effect is strongest for young people from low socioeconomic‐status families.     

Disappointment for others

Two studies examined when and why people experience disappointment for others. Study 1 demonstrated that participants reported disappointment for another's outcome only when the outcome had strong personal implications. Study 2 demonstrated that self-image concerns rather than empathy or resource concerns mediated the experience of disappointment for others. Collectively, these findings suggest that people experience disappointment for others when those outcomes implicate the self-image.     

Attending to the fear in your eyes: Facilitated orienting and delayed disengagement

Fearful facial expressions convey threat-related information and automatically elicit modulations in spatial attention. The eye-region appears to be a particularly important feature for recognising and responding to fearful faces. However, it is unknown as to whether or not fearful eyes initiate modulations in spatial attention. In the current study, three dot-probe experiments with fearful and neutral eye stimuli were performed. The results of Experiment 1 demonstrate that fearful eyes capture spatial attention through facilitated attentional orienting to threat and delayed attentional disengagement from threat. In Experiments 2 and 3, these attentional effects were replicated, while ruling out the influence of overall size/shape and brightness differences between fearful and neutral eyes, respectively. Thus, fearful eye-whites appear to be a salient feature of fearful facial expressions that elicit modulations in spatial attention.
