Maternal Emotion-related Socialization and Preschoolers' Developing Emotion Self-awareness

Preschoolers' ability to demonstrate awareness of their own emotion is an important socio‐emotional competence which has received increasing attention in the developmental literature. The present study examined emotion self‐awareness of happiness, sadness, and anger in response to a delay of gratification task in 78 preschool children. Maternal emotion‐related socialization behaviors (ERSBs) including reported emotional expressivity, responses to her child's emotions, and observed emotion talk, were examined as predictors of children's emotion self‐awareness skill one year later. Results show that, after controlling for receptive language ability, supportive ERSBs were predictive of high self‐awareness of happiness whereas non‐supportive ERSBs were predictive of low self‐awareness of sadness. The results demonstrate that the concordance between observed and self‐reported emotion serves as a useful index of children's awareness of their emotional experience.     

Assessing the Effects of Observational Conditioning and Response-Contingent Pairing on the Vocalizations of Children With Autism Spectrum Disorder

Children with autism spectrum disorder (ASD) often display impairments in communication, such as limited echoic behavior, few vocal-verbal responses, and a lack of functional communication. One potential way to foster the acquisition of vocal responses in individuals with disabilities is by conditioning vocalizations as reinforcers. Conditioning procedures include stimulus–stimulus pairing, response-contingent pairing (RCP), operant discrimination training, and observational conditioning (OC). However, previous research has not evaluated whether OC can be used to condition vocalizations as reinforcers. The current study assessed whether two conditioning procedures, RCP and OC, were effective in conditioning vocalizations as a reinforcer and also evaluated their effect on the rate of vocalizations. Participants included three children with ASD, ages 5–10 years old. During the conditioning phase, rates of vocalizations during the RCP and OC conditions and a control condition were compared within an adapted alternating-treatments design. Reinforcer assessments were completed in a multielement design, pre- and postconditioning, to assess whether the target vocalizations acquired reinforcing properties. A conditioning effect and an increase in the rate of vocalizations were observed for two of the three participants; however, the conditioning effect was minor for one participant. Overall, the results of this study indicate both the RCP and OC procedures may be beneficial in increasing vocalizations for some children and could be incorporated into clinical programs and further explored in future research.     

Maternal Interactive Style Across Contexts: Relations to Emotional, Behavioral and Physiological Regulation During Toddlerhood

Sixty-five mothers and their 24-month-old toddlers were observed in a series of laboratory procedures designed to assess relations between maternal interactive style and emotional, behavioral and physiological regulation. Emotional regulation was assessed by examining the child's behaviors (aggression, distraction, object focus) when confronted by three emotion-eliciting tasks. Behavioral regulation was measured by examining children's ability to comply to maternal requests and to inhibit behavior during a delay task. Physiological regulation was derived from children's cardiac vagal tone responses to emotionally-arousing situations. Maternal interactive style was assessed by examining mothers' strategies for child behavior management (negative controlling, positive guidance) during three mother-child tasks. Maternal behavior was related to regulation in each of the three domains. Negative maternal behavior was related to poor physiological regulation, less adaptive emotion regulation, and noncompliant behavior. Positive maternal behavior was correlated with compliance, but not with any of the physiological or emotional measures. These findings are discussed in terms of the adaptive value of self-regulation in early development, and the importance of identifying the causal relations between maternal behavior and child regulation.     

Development of Shyness: Relations With Children's Fearfulness,Sex, and Maternal Behavior

The relations of childhood fearfulness (observed and adult reported) and adult‐reported shyness at 18 (n = 256) and 30 (n = 230) months of age were assessed. Fear was positively related to shyness concurrently and longitudinally, but slightly more consistently at 18 months. The moderating roles of observed maternal sensitivity and children's sex in the relation between 18‐month fearfulness and 30‐month shyness, and between 18‐ and 30‐month shyness, were tested. The positive relation between mother‐reported fearfulness and shyness was strongest for sons of insensitive mothers but was not significant for daughters of sensitive, average, or insensitive mothers. The positive relation between mother‐reported 18‐ and 30‐month shyness was strongest for sons of insensitive mothers and for daughters of sensitive mothers. Moreover, when using scores of fear or shyness that were independent of each other, 18‐month mother‐reported fearfulness continued to interact with sex and sensitivity to predict 30‐month shyness; however, the positive relation between Time 1 and Time 2 shyness was consistent across sex and levels of sensitivity.     

Popweaver: a program for interpolation and visualization of census and other sparsely collected data

Demographic data is essential to inform socio-economic, epidemiological and other time series analyses. However, demographic data based on interpolations performed on census surveys spaced several years apart often bear severe quality problems, which propagate into studies that make use of those datasets. We present Popweaver, a user-friendly and free software that allows users to interpolate demographic data (stratified by age, geography, socio-economics, and other layers), visually inspect them, and generate ready-to-submit figures and three-dimensional spreadsheets with the results for further analyses. We illustrate the use of Popweaver with census data (1980, 1991, 2000, 2010) from Brazil, and its potential to reveal important demographic trends.

Twenty years of heritage studies – the showbiz of history?

This paper is part of a collective retrospective convened in 2014 looking back at various disciplines in the Humanities at Wits over the 20 years of democracy. The seeds of the heritage studies programme at Wits were sown in 1990 when it became apparent that the apartheid regime was about to cede to a more democratic regime, creating a new opportunity for Wits academics to engage with public institutions. The paper discusses this moment against the background of the History Workshop at Wits, which hosted some of the discussions about public culture in the early 1990s. It attempts to elucidate the origins of the heritage studies programme at the university and describe some of its features. The paper follows the migration of the programme from Social Sciences to the Wits School of Arts, outlining some of the philosophical ramifications of its relocation.     

Predicting Undergraduate Student Retention in STEM Majors Based on Career Development Factors

A research gap exists with regard to examining the influence of career interventions and career readiness assessments on student retention in college majors related to science, technology, engineering, and mathematics (STEM). To address this gap, the authors examined 3 variables as potential predictors of retention in STEM‐related majors: (a) a STEM‐focused career planning intervention, (b) students' initial major declarations, and (c) changes in scores on a measure of career readiness. Results revealed that all 3 independent variables were significant predictors of STEM retention but did not accurately predict students who would not be retained. These results have implications for undergraduate STEM initiatives, college counselors and career advisors, and researchers investigating the predictors of STEM retention. Future research should include additional predictor variables.     

Household energy consumption: Community context and the fuelwood transition

We examine the influence of community context on change over time in households’ use of non-wood fuels. Our theoretical framework builds on sociological concepts in order to study energy consumption at the micro-level. The framework emphasizes the importance of nonfamily organizations and services in the local community as determinants of the transition from use of fuelwood to use of alternative fuels. We use multilevel longitudinal data on household fuel choice and community context from rural Nepal to provide empirical tests of our theoretical model. Results reveal that increased exposure to nonfamily organizations in the local community increases the use of alternative fuels. The findings illustrate key features of human impacts on the local environment and motivate greater incorporation of social organization into research on environmental change.
