Background and Aims: The purpose of this exploratory study was to expand existing literature on prelinguistic vocalizations by reporting results of the first home-based longitudinal study examining a wide variety of behaviors and characteristics, including early vocalizations, across infants at low and elevated risk of autism spectrum disorder…

Bullying in basic and secondary schools has received considerable research attention; empirical investigation of the phenomenon among university students has, however, been overlooked. There is a paucity of such studies in African universities. This study examined the prevalence and forms of bullying in a Ghanaian technical university, as well as…

The aim of this study is to determine the attitudes of special education teacher candidates, who have great responsibilities in terms of environmental education, towards the environment and to compare these attitudes according to various variables. For this purpose, a 4-point Likert-type Environmental Attitude Scale consisting of 35 items was used…

Many community colleges receive performance-based funding; therefore, many of these colleges have implemented student success courses in an effort to increase persistence and completion. The purpose of this quantitative study was to examine the influence of the student success courses on persistence at Ivy Tech Community College. This study…

The current meta-analytic review analyzed 43 studies published in English, Chinese, and Japanese to determine the effects of caregiver involvement for promoting communication skills of individuals with ASD and IDD. Tau-U effect sizes, the Kruskal-Wallis H test, and the Dunn post hoc test were employed to calculate for moderator analyses: child…

The digital age is reshaping learning and instruction and encouraging educational technology advances within higher education institutions. However, online faculty are not integrating technology into their classes despite the technology related professional development they receive. The purpose of this quantitative study was to determine if a…

The purpose of this convergent mixed methods study was to examine environmental worldviews and to explore influencing factors, such as the relationship between affective disposition toward learning experiences and environmental worldviews, for students at a public four-year university. A convergent mixed methods design provided qualitative and…

This study was designed to investigate the factors that affect teacher attrition in southern Mississippi. The population for this study consisted of 145 teachers working in various school levels. The teachers were asked to respond to survey questions on Likert-type scale. The purpose of this quantitative study was to analyze teacher perceptions of…

The success of a choir depends on the integrity, concentration and team logic to be formed within the group under the leadership of the choir conductor. Some dimensions of team perception are considered to be important for choral success such as knowing the aims of the choir, being aware of each other's talent levels, sharing the feeling of…

We investigated the developmental courses of both implicit and explicit racial biases in relation to the perceived social status of outgroups. We did so by assessing these biases among Chinese participants (N = 200, age range from 4- to 19-year-olds) toward 2 different other-race groups that differ in terms of perceived social status (i.e., Whites…

The present study focuses on the development of Spanish pronominal processing. We investigate whether the "pronoun interpretation problem" (i.e., reflexive pronouns comprehension is resolved at an earlier age than that of personal pronouns, also known as the "Delay of the Principle B Effect"), which has been documented in other…

Purpose: Dysphagia in Parkinson's disease (PD) is a major cause of depression and reduced quality of life (QOL). PD-related dysphagia often involves lingual dysfunction and weak pressure generation. The relation of disordered lingual pressure generation to swallowing-related QOL in persons with PD remains unknown. Method: Twenty-four persons with…

Purpose: The goal of this study was to analyze verbal and nonverbal maternal response types following infant vocalizations in younger (ages 4-8 months) versus older (ages 10-14 months) infant groups and their potential implications for infant vocal development or word learning. Method: Maternal response types that occurred within 3 s of infant…

Many well-established developmental theories concentrate on strategies of regulation and try to explain how individuals compensate for possible losses in old age. In public debates, and in laypeople's perception of aging, however, activity and productivity seem to be central concepts associated with successful aging. The present research focuses…

Joint engagement--the sharing of events during social interactions--is an important context for early learning. To date, sharing topics that are only heard has not been systematically documented. To describe the development of auditory joint engagement, 48 child-parent dyads were observed 5 times from 12 to 30 months during seminaturalistic play.…
