Technology-based versus in-person deposit contract treatments for promoting physical activity

Deposit contracts involve participants depositing their own money and earning it back contingent on behavior change. Deposit contracts are empirically supported treatments for promoting health behavior, but they have a history of poor uptake. We compared the effectiveness and acceptability of technology-based versus in-person deposit contracts for promoting physical activity with 12 individuals. Participants' daily step counts were monitored using Fitbits across 6 weeks, and treatment preferences were assessed at the end of the study. The 2 types of treatments were equally effective in increasing physical activity, but the technology-based deposit contracts were preferred by most participants. Most participants also reported that their preference was related to convenience. Technology-based implementation may be one way to improve deposit contract uptake, while maintaining similar effectiveness compared to in-person procedures.

Factors associated with responses to sexual harassment and satisfaction with outcome

This study examined contextual and behavioral factors and types of responses to sexual harassment in relation to harassed employees' satisfaction with the outcome of sexual harassment situations. Subjects were 105 male and female faculty and staff members (89.5% Caucasian; 5.7% multiethnic/multicultural; 4.8% unspecified) employed by a midwestern university who reported experiencing unwanted sexual attention on the job. Results undicated that employees responded more strongly to unwanted sexual behavior if they perceived it as sexual harassment and if they perceived their work climate as encouraging the problem. Harassed employees' gender, power, and perceptions of the work climate were all associated with their satisfaction with the situation outcome. Although making a formal or informal complaint was not associated with greater satisfaction, talking to the harasser without using aggressive communication strategies increased the likelihood of a satisfactory outcome for the employee. Talking to family or friends, a response used by women more often than men, was associated with dissatisfaction. Suggestions for further research are discussed.This research was primarily funded by the Center for Public Affairs Research at the University of Nebraska at Omaha.

An investigation of verbal interaction, knowledge of sexual behavior and self-concept in adolescent mothers

Variables commonly considered to be major factors in contributing to the incidence of adolescent pregnancy may be only part of the total pattern. This study sought to examine the adolescent mothers' communication with significant others and their knowledge about sex, pregnancy, and birth control methods. Self-concepts of the adolescent mothers were compared with those of the published norms of the Tennessee Self-Concept Scale. The study included 23 adolescent mothers between the ages of 13 and 19 who were gravida 1 as indicated by their medical records. They were given a questionnaire constructed from previous research. They also completed a communication scale and the Tennessee Self-Concept Scale. The findings of the present study indicated that most adolescent mothers considered their communication with their parent mothers to be one of mutual understanding. However, it appears that most adolescent mothers obtain much of their information about sex, pregnancy, and birth control methods from significant others. The self-concepts of these adolescent mothers were lower in comparison to the norm. The results indicate a need for further research in the area of adolescent sexual development, sex education in the school, and increased involvement of parents in the communication of sexual mores.     

Mentors' Influence on Mexican American Students' Career and Educational Development

Effects of mentoring on Mexican American high school students' career aspirations were examined. Results indicated most students had a mentor, and mentors were most helpful through role modeling, verbal encouragement, personal support, and providing career guidance. Gender differences were found on several outcome variables but were not detected based on sex or ethnic match, or the presence of a mentor. Los efectos de mentoring en estudiantes mexicanos de la high school en aspiraciones de carrera se examinaron. Los resultados indicaron la mayoría de los estudiantes tuvieron un mentor, y mentores eran muy útiles por el papel que modela, el ánimo verbal, apoyo personal, y proporcionar la guía vocacional. Las diferencias del género se encontraron en varias variables del resultado pero no fueron discernidas basado en la presencia de y del sexo o el igual étnico con un mentor.     

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.
