Effects of Delayed Audio-Based Self-Monitoring on Teacher Completion of Learning Trials

Although instructors may teach effective instructional behaviors in pre-service training programs, pre-service teachers frequently do not generalize those behaviors to classroom practicum settings. Feedback within the practicum setting is necessary to promote generalization, but is often limited by university supervisors’ availability. Using a multiple-probe design across 3 pre-service teachers, we investigated audio self-monitoring as a method to provide feedback on the number of learning trials completed during the prior learning review section of lessons. A completed learning trial represented an opportunity for the students to both respond to a prompt and receive feedback from the pre-service teacher and represents the smallest unit of complete instruction. Results indicated that self-monitoring increased the percentage of learning trials completed by pre-service teachers, but had modest effects on rate of learning trials delivered. These findings are discussed in light of the need for methods that help bridge the gap between university-based training and classroom application of key instructional skills.     

REM Sleep Bout Duration and Frequency in PTSD

The few pharmacological treatments shown to be effective in reducing sleep disturbance in posttraumatic stress disorder (PTSD) might work through normalization of rapid eye movement (REM). However, evidence of REM sleep disturbance in PTSD has been inconsistent and the definition of REM bout has varied as well. In this study, we compared polysomnographic findings in adults with PTSD to both normal sleepers and insomniacs. We found no differences between those with and without PTSD on REM bout frequency or duration. We did, however, find gender differences within our PTSD sample as consistent with a previous review suggesting that males with PTSD are more likely to demonstrate REM sleep disturbance. Consensus on REM bout definition is needed, in addition to studies powered to detect gender differences.     

A Note on Stability in Force Applied to Control a Repetitive Task With the Legs

The forces applied to pedals during cycling were collected every 40 ms from approximately 29,000 movement repetitions. Intra-cycle mean values of force and its variability were significantly correlated, supporting Schmidt–s impulse variability theory of within-movement activities of the legs. In addition, as mean forces approached peak values, coefficients of variation decreased. From averages taken minute by minute, intra-cycle forces were seen to rise or fall in concert, implying that the pattern as a whole constituted a significant neuromuscular unit of control.     

Toddlers’ joint engagement experience facilitates preschoolers’ acquisition of theory of mind

Forty‐two children participated in a longitudinal study that investigated the relationship between their joint engagement experience when toddlers and their development of theory of mind when preschoolers. Controlling for language comprehension at 30 months, higher preschool false belief scores were associated with more time in coordinated joint engagement earlier (18–21 mo, β= .34) and in symbol‐infused joint engagement later (27–30 mo, β= .35) in toddlerhood. Findings suggest that the early foundation of theory of mind development is laid as toddlers attend to both social‐emotional and symbolic aspects of shared events.     

Personality and gender differences in global perspective

Men's and women's personalities appear to differ in several respects. Social role theories of development assume gender differences result primarily from perceived gender roles, gender socialization and sociostructural power differentials. As a consequence, social role theorists expect gender differences in personality to be smaller in cultures with more gender egalitarianism. Several large cross‐cultural studies have generated sufficient data for evaluating these global personality predictions. Empirically, evidence suggests gender differences in most aspects of personality—Big Five traits, Dark Triad traits, self‐esteem, subjective well‐being, depression and values—are conspicuously larger in cultures with more egalitarian gender roles, gender socialization and sociopolitical gender equity. Similar patterns are evident when examining objectively measured attributes such as tested cognitive abilities and physical traits such as height and blood pressure. Social role theory appears inadequate for explaining some of the observed cultural variations in men's and women's personalities. Evolutionary theories regarding ecologically‐evoked gender differences are described that may prove more useful in explaining global variation in human personality.     

Multi-Party,Whole-Body Interactions in Mathematical Activity

This study interrogates the contributions of multi-party, whole-body interactions to students' collaboration and negotiation of mathematics ideas in a task setting called walking scale geometry, where bodies in interaction became complex resources for students' emerging goals in problem solving. Whole bodies took up overlapping roles representing geometric objects, contributing to the communication and negotiation of problem-solving strategies and engaging as mathematical instruments for representation.     

Service Delivery Outcomes in ASD: Role of Parent Education,Empowerment, and Professional Partnerships

Children with Autism Spectrum Disorder (ASD) utilize a greater number of healthcare services compared to children with other developmental disabilities. Despite this, children with ASD remain at high risk for unmet service needs, which are compounded by differences in socioeconomic status (SES). Both empowerment and parent-professional partnership play a role in service outcomes and may be especially important in understanding these service disparities. Our goal was to better understand the contributions of these variables to service disparities in families of children with ASD. Two-hundred forty-nine parents of children with ASD between the ages of 3 and 20 participated in this online survey. Results support previous research highlighting high levels of unmet needs that are exacerbated by differences in parent education, a common indicator of SES. Empowerment and parent-professional partnership also predicted service delivery outcomes. While high quality partnership predicted greater service adequacy, empowerment was inversely related to services. Furthermore, an interaction found that highly empowered families experiencing poor quality partnerships reported worse service delivery outcomes, while empowerment was not a factor in services for families experiencing high quality partnerships. Parent-professional partnership partially mediated the relationship between parent education and service delivery outcomes. As such, increasing parent-professional partnerships through family-centered care and professional training may help to reduce education-related service disparities and improve satisfaction with care for families and children with ASD.
