Despite the fact that third parties are present during a substantial amount of face-to-face interviews, bystander influence on respondents' response behavior is not yet fully understood. We use nine waves of the German Family Panel "pairfam" and apply fixed effects panel regression models to analyze effects of third-party presence on…

This study examined if listener behavior and responding by exclusion would emerge after training 3 participants with autism to tact stimuli. Tacts for 2 of 3 stimuli were directly trained using discrete trial training methodology and were followed by an auditory-visual discrimination probe in which auditory-visual discrimination by naming (i.e.,…

When researchers code behavior that is undetectable or falls outside of the validated ordinal scale, the resultant outcomes often suffer from informative missingness. Incorrect analysis of such data can lead to biased arguments around efficacy and effectiveness in the context of experimental and intervention research. Here, we detail a new…

The authors sought to further the understanding of reading processes and their links to comprehension using two reading tasks for elementary-grade students. One hundred sixty-six students in grades 2-5 were randomly assigned to one of two conditions: reading with questions presented concurrently with text or reading with questions presented after…

Findings from a randomized controlled design study of an ability-based versus needs-based approach to response-contingent learning among children with significant developmental delays and disabilities who did not use instrumental behavior to produce reinforcing consequences are reported. The ability-based intervention and needs-based intervention…

The results showed predictable male and female differences and differences between the sexual behavior of the Norwegian sample and American samples tested by other investigators. The study lent some support to an appetitional theory of sexual motivation. (Author)

A 31-item questionnaire was given to 199 students, 20 of whom were found to have histories of previous suicide attempts. Results support the necessity of a distinction between groups within a nonsuicidal comparison population and that a quantitative relationship between frequency of suicidal thought and likelihood of attempted suicide exists.…

Balanced groups of obese and thin persons, men and women, lone eaters and group eaters, were unobtrusively observed. Observers noted occurrence of extraneous responses, counted bites and chews, and rated tension, mood, and food enjoyment. Results were reported at the International Congress on Obesity, London, October 1974. (Author)

Study indicates democratic leadership style produces highest productivity; data is tabulated. (Editor/SP)

Young (N=18) and older (N=18) adults participated in a vocabulary task involving varying degrees of risk with a payoff structure that varied either directly or inversely with risk. In contrast to prior research using constant payoff structures, results did not indicate that older adults are more cautious than young adults. (Author)

In the current study, momentary time sampling (MTS) and partial-interval recording (PIR) were compared to continuous-duration recording of stereotypy and to the frequency of self-injury during a treatment analysis to determine whether the recording method affected data interpretation. Five previously conducted treatment analysis data sets were…

Certain characteristics of a Taylor (1965) competitive reaction time task contribute to a lack of awareness of contingencies that exist between two aggressors. The opponent's contingent response to the subject's specific shock setting may be obscured by the reaction time competition, thus concealing the matching contingency. Nine separate steps…

The relative effects of imagerial covert rehearsal with attentional shifts and the use of an independent reinforcing agent in a covert reinforcement therapy were compared. A 17-year-old female student, requesting treatment for a snake phobia, served as the subject. The phobia was measured along four dimensions: behavioral approaches to a live…

Fifteen "criminal" and political uprisings from inmate movements in American, Soviet, and German prisons are compared. Conditions of deprivation related to prison violence are linked with attitudinal, structural, and temporal factors. Findings are that inmate movements are a rare phenomenon in comparison with isolated prison uprisings. (KC)
