Purpose: This study evaluated the accuracy of respiratory calibration methods for estimating lung volume during speech breathing. Method: Respiratory kinematic data were acquired via inductance plethysmography in 32 young adults, 22 older adults, and 13 older adults with Parkinson's disease (PD). Raw rib cage (RC) and abdomen (AB) signals (V) were…

This paper explores whether training programs were effective in improving labor market performance of individuals, in particular wages and employment probability, in South Korea. The regression analyses using the data from Korean respondents in the Program for the International Assessment of Adults Competencies (PIAAC) survey show the strong…

Attention control abilities are relevant for learning success. Little is known about the development of audio-visual attention in early childhood. Four groups of children between the ages of 4 and 10 years and adults performed an audio-visual distraction paradigm (N = 106). Multilevel analyses revealed increased reaction times in a visual…

While instructors are a critical component of the education paradigm, research into instructor perspectives on online education are sparse. Previously reported research from a larger study demonstrated that online and face-to-face instructor perspectives significantly differed on many factors related to online education. The purpose of this phase…

At the beginning of the components that affect the performance of the swimmers' training and race planning, the stroke count (SC), stoke lenght (SL) and stroke rates (SR) of the swimmers are important. For this reason, it is important for both athletes and coaches to know how to develop and change these characteristics with age. The aim of this…

Little is known about how, when, or why individuals with intellectual and developmental disabilities (IDD) retire. Recognizing the changing needs of older adults with IDD is critical to support person-driven services and development of best practices in aging transitions. Using secondary analysis of the 2016 to 2017 National Core Indicators--Adult…

The current study examines how second language (L2) users differentially assess the comprehensibility (i.e., ease of understanding) of foreign-accented speech according to a range of background variables, including first language (L1) profiles, L2 proficiency, age, experience, familiarity, and metacognition. A total of 110 L2 listeners first…

Communication Complexity Scale (CCS) scores for 269 minimally verbal participants were examined to determine if communicator behavior and task and communicator characteristics were related to scores in a manner consistent with theoretical and research evidence expectations. Each participant completed an interactive assessment with 6 joint…

Among the factors that determine an organization's effectiveness, values are critical elements. However, little is known about the values of those who work in schools. The research reported here is an initial step in exploring the value orientations of educators in Greece. The findings are used to formulate recommendations for extended…

This paper aims to advance our understanding of how children's use of vocabulary in writing changes as they progress through their school careers. It examines the extent to which a model of lexical sophistication as use of low-frequency, register-appropriate words adequately captures development in vocabulary use across the course of compulsory…

The development of math reasoning and 3-d mental rotation skills are intertwined. However, it is currently not understood how these cognitive processes develop and interact longitudinally at the within-person level -- either within or across genders. In this study, 553 students (52% girls) were assessed from fifth to seventh grades on 3-d mental…

Empathy is an essential component of human social life. It requires the ability to understand another's mental state and respond with an appropriate emotion or action. Individuals with autism spectrum disorder (ASD) have been described to exhibit atypical empathic responses which limit communication and social interactions. This review highlights…

In this paper, we use dimensions of the construct "science identity" as an analytic lens to tap into the motivation and learning of science center visits. This exploratory empirical study was based on a large international dataset drawn from 10 science centers in countries across Europe, Asia, and North America, to investigate the…

Using public information from birth certificates and prison records from Florida, we adopt a reduced-form approach to estimate the effect of relative age on the probability of incarceration in adulthood (until age 30-40). We use a Regression Discontinuity Design around the cutoff date for Kindergarten enrollment (Sept. 1). We find strong evidence…

Open educational resources (OERs) are increasingly adopted in non-formal education contexts. However, little research has been conducted to investigate the self-directed learning patterns of non-formal learners using OERs. A lack of knowledge about non-formal learners precludes discussions on how to support their self-regulated learning in open…
