In this article, I present my view on the significant developments and theoretical/empirical tipping points in nonverbal and verbal deception and lie detection from the last 30 years and on prospects for future research in this domain. I discuss three major shifts in deception detection research: (a) From observing target persons' nonverbal…

The present work examines the impact of code-switching (CS) on novel word learning in adult second language (L2) learners of Spanish. Participants completed two sessions (1-3 days apart). In the first session, they were taught 32 nonwords corresponding to novel creatures. Training occurred across 4 conditions: (1) a sentence in English only, (2) a…

How do school professionals distinguish between social, communication, and behavioral differences observed in typically developing English language learners (ELLs) and those ELL students with autism spectrum disorder (ASD)? Informed consideration is necessary to avoid inaccurate identification and to ensure appropriate supports are provided;…

From a dynamic systems perspective, transition points in development are times of increased instability, during which behavioral patterns are susceptible to temporary decoupling. This study investigated the impact of the vocabulary spurt on existing patterns of communicative coordination. Eighteen typically developing infants were videotaped at…

Purpose: The purpose of this study was to examine and compare the development of proto-imperative and proto-declarative utterances in normally developing, non-neonatally screened, profoundly deaf toddlers. Method: Both types of proto-declarative are considered to be the most basic prelinguistic and early linguistic communicative functions.…

The effects of systematically varied verbal and nonverbal components of teachers' evaluative behavior upon children's perceptions and attitudes were studied within an experimental classroom. Subjects were 126 sixth-grade students. (Author)

In the context of an ethnographic study of nonverbal communication within the Japanese home environment, issues in the use of videotape recordings for data gathering are discussed. The study investigated language use and behavior of Japanese host families in homestay settings, focusing on the use of nonverbal behavior to facilitate communication.…

The six studies reported on here sought to determine if patterns of behaviors could be determined in the verbal and nonverbal communications of teachers toward pupils, and if there were differences in these patterns when such variables as sex, race, ability, age, and socioeconomic status were considered. Videotapes of over 100,000 teacher/pupil…

Five components of communication competence have been derived from research: affiliation/support, empathy, behavioral flexibility, social relaxation, and interaction management. This paper describes these dimensions of communication competence; it then reports on a study in which two college females judged by their peers to be effective…

Both North American and Latin American business professionals were investigated in a study that focused on the perceived communication problems between the two groups. A number of major areas of interest were considered, including the following: (1) source of credibility (what dimensions of personality were seen as most desirable in the…

Two studies investigated the effects of training on how accurately observers (college students) decoded a complex nonverbal stimulus. In the first experiment, observers viewed silent videotapes of 16 third and fourth-grade school children who were listening to an easy or a difficult lesson. Half of the children were responding spontaneously, while…

The purpose of this research project was to develop clearer definitions of the categories of the Nonverbal Category System, an instrument developed in conjunction with an earlier study of nonverbal behavior of young children as it relates to decision making. A second purpose was to establish whether the instrument could be employed in studying…
