Atypicalities in sleep and semantic consolidation in autism

Sleep is known to support the neocortical consolidation of declarative memory, including the acquisition of new language. Autism spectrum disorder (ASD) is often characterized by both sleep and language learning difficulties, but few studies have explored a potential connection between the two. Here, 54 children with and without ASD (matched on age, nonverbal ability and vocabulary) were taught nine rare animal names (e.g., pipa). Memory was assessed via definitions, naming and speeded semantic decision tasks immediately after learning (pre‐sleep), the next day (post‐sleep, with a night of polysomnography between pre‐ and post‐sleep tests) and roughly 1 month later (follow‐up). Both groups showed comparable performance at pre‐test and similar levels of overnight change on all tasks; but at follow‐up children with ASD showed significantly greater forgetting of the unique features of the new animals (e.g., pipa is a flat frog). Children with ASD had significantly lower central non‐rapid eye movement (NREM) sigma power. Associations between spindle properties and overnight changes in speeded semantic decisions differed by group. For the TD group, spindle duration predicted overnight changes in responses to novel animals but not familiar animals, reinforcing a role for sleep in the stabilization of new semantic knowledge. For the ASD group, sigma power and spindle duration were associated with improvements in responses to novel and particularly familiar animals, perhaps reflecting more general sleep‐associated improvements in task performance. Plausibly, microstructural sleep atypicalities in children with ASD and differences in how information is prioritized for consolidation may lead to cumulative consolidation difficulties, compromising the quality of newly formed semantic representations in long‐term memory.     

Problem and program linkage: The early and periodic screening,diagnosis and treatment program as a means of preventing and detecting child abuse

This paper presents a case model for linkage of social service delivery programs with the prevention and detection of child abuse. The example of problem and problem linkage is given for the Early and Periodic Screening, Diagnosis and Treatment Program (EPSDT), the nation's largest preventive child health screening program designed to detect and treat early childhood medical and developmental conditions in indigent children. The screening activities combined with the efforts to educate parents as to the nature of normal child development suggests that the EPSDT program may be used to prevent the development of conditions that may lead to abuse as well as to identify children who have been abused.     

HIV/STD Risk Factors for Women with Violent Male Partners

This study compared 167 women, categorized as nonabused, emotionally abused, or physically abused in their primary relationships, on sexual risk factors. Physically abused women differed in several ways: greater STD risk, psychosocial distress, and substance use; more traditional gender role beliefs; lower self-esteem; more likely to have been raped and to engage in sex for pay; and less likely to attend the project's STD/HIV risk reduction groups. Within primary relationships, they differed in amount of decision-making power about safer sex, likelihood of nonmonogamy, use of substances before sex, and self-efficacy about initiating condom use. African American women reported higher rates of emotional abuse than White women, a finding related mainly to their lower socioeconomic status in this sample.     

Introduction to the Special Issue: Defining Gender,Relationships, and Power

Limitations in our knowledge of women's lives are most strikingly revealed by social scientists' attempts to respond to the HIV/AIDS crisis. Most psychological research studies Anglo middle- and upper-middle-class college students, to the detriment of our current need for knowledge of the populations of women most at risk for HIV/AIDS, who are non-Anglo, poor, and less educated. This special issue was initiated by the Task Force on Women and HIV of the Society for the Psychology of Women, Division 35 of the American Psychological Association. Our immediate objective was to present in a single issue a full range of current research practices and needs along with any exemplary innovations, and to identify the dilemmas facing investigators that might be blocking theory development. We hope to inspire, inform, and energize those whose contributions are most needed to advance theory and research that will be helpful to researchers and practitioners of HIV prevention and services. The long-range goal of this special issue is to stimulate innovative and useful theory development by gathering empirical work that challenges current theory and shows the role of culture.     

The Political Universe of Lyndon B. Johnson and His Advisors: Diagnostic and Strategic Propensities in Their Operational Codes

This study uses the Verbs in Context System (VICS) to analyze and compare the operational codes of President Lyndon Johnson and his advisors during the Vietnam conflict. The initial focus is on changes in Johnson's general operational code as revealed in public statements during the period leading to the decisions to bomb North Vietnam and to intervene with ground forces in South Vietnam. Johnson's public operational codes for the domestic, foreign, and Vietnam domains are then compared, and his public operational code for the Vietnam conflict is contrasted with the private operational code of his Vietnam advisors (as expressed in private memoranda). Period effects, domain effects, and other differences are revealed between the views of Johnson and those of his advisors.     

Assessing Psychological Characteristics at a Distance: Symposium Lessons and Future Research Directions

The symposium papers show that differences in sources and context clearly matter in the 'at-a-distance' assessment of a leader's psychological characteristics. The stability of both cognitive and personality attributes decreases as observations focus on shorter time frames, more spec fic policy domains, and private rather than public arenas. Despite these qualifications on the use of texts to profile individual leaders, the indices of social cognition and personality do discriminate individual differences between leaders. Because the results reveal significant differences in assessing individual leaders over time with multiple sources and at different levels of analysis, it becomes more worthwhile to investigate research questions that would be moot in the absence of important source, context, or aggregation effects. With the use of automated content analysis and greater access to data from electronic sources, it is now easier to carry out quantitative content analyses of psychological characteristics and to confirm or qualify the insights generated in this symposium.     

The effects of physical fitness and feeling vigorous on self-rated health

OBJECTIVE: We prospectively studied the hypothesized beneficial effects of feeling vigorous and of objective physical fitness (gauged based on functional capacity) on subsequently assessed self-rated health (SRH), controlling for possible confounders known to be precursors of SRH and of our predictors. We also investigated the reverse-causation hypothesis that SRH predicts subsequent vigor and functional capacity. DESIGN: Participants were apparently healthy employees (N = 779) who underwent a routine health check at two points of time, Time 1 (T1) and Time 2 (T2), about 18 months apart. We used regression analysis, predicting T2 SRH by T1 SRH, the control variables, and T1vigor and functional capacity. MAIN OUTCOME MEASURES: Vigor was assessed using the Shirom-Melamed Vigor Measure; objective physical fitness was indicated by functional capacity following a treadmill exercise, and self-rated health was measured by a single item. RESULTS: As hypothesized, we found that the change in T2 SRH was positively predicted by T1 vigor, functional capacity, and their interactive term. Testing the reverse causation paths, we found that T1 SRH did not predict subsequent functional capacity and was a relatively weak predictor of subsequent vigor. CONCLUSION: The affective state of vigor and objectively assessed functional capacity interact to predict subsequent changes in self-rated health.
