Mimicry involves unconsciously copying the actions of others. Increasing evidence suggests that autistic people can copy the goal of an observed action but show differences in their mimicry. We investigated mimicry in autism spectrum disorder (ASD) within a two-dimensional virtual reality environment. Participants played an imitation game with a…

The three algorithms most frequently selected by behavior-analytic researchers to compute interobserver agreement with continuous recording were used to assess the accuracy of data recorded from video samples on handheld computers by 12 observers. Rate and duration of responding were recorded for three samples each. Data files were compared with…

This dissertation investigates how distributional information in the speech stream can assist infants in the initial stages of acquisition of their native language phonology. An exploratory statistical analysis derives this information from the adult speech data in the corpus of conversations between adults and young children in Russian. Because…

The study of social dominance has a long tradition within the peer relationships literature, but rarely has the topic been investigated observationally and longitudinally within other salient close relationships. The present study investigated the role of experiences in social relationships and adjustment indices in childhood in predicting later…

Investigates gender differences in smoking behavior by observing 292 men and 648 women smoking in a university workplace. Finds that men take longer breaks, smoke more cigarettes, and inhale more often than women. (MW)

Some research has found that observers believe overt mimicry is socially unacceptable and embarrassing in the presence of a stranger. It was hypothesized that observers would inhibit their mimicry of learned pairs of gestures in the presence of a stranger, and that their learning would be adversely affected unless they compensated for the…

Twenty-seven severely mentally retarded patients, all of whom manifested body-rocking in their normal ward environments, were systematically observed. (SBH)

Examines the tendency of observers to make less reliable recordings of behavorial events when a calibrating observer is absent. Using four different multicategory systems, 26 experienced observers coded 200 hours of videotaped family interactions. Concludes that observers lapse into a less attentive "set" prior to coding without a…

A survey of observed sexual behavior in an integrated unit of 30 severely retarded people aged 10 to 33 years showed that most behavior could be described as "appropriate." (Author)

A study investigated (1) how adult responses vary with children who display different rates of positive social behaviors, and (2) predictive sequential relationships between specific types of child and adult behavior within an interaction. Pretest data were used to select nine girls from 4 to 6 years of age who ranged from low to high in their…

The representativeness of behavioral observation samples with durations of less than the whole time of interest was investigated with five profoundly mentally retarded physically handicapped adults in an institutional setting. It was found that the session representativeness was a function of the relative duration of the behavioral categories and…

This guide is intended to help the literacy practitioner in the identification of adults with learning disabilities. These adults have worked diligently for a year or more to improve comprehension skills, writing and spelling, or work skills, yet, have made little progress. The role of screening as only the first step in a process involving a…
