Many present day classroom teachers face greater challenges than perhaps during any time in the past. Teachers are expected to: (a) provide evidence-based instruction to ensure that students make adequate yearly progress under the No Child Left Behind Act of 2001 (NCLB); (b) serve an increasingly diverse group of students including students with…

Annually an estimated 3 million or more children are exposed to acts of domestic violence between adults in their homes. These children are at risk for abuse themselves as well as other immediate and long-term problems, especially if they have been exposed to repeated episodes of domestic violence. Multiple behavioral manifestations, including…

The purpose of this study was to examine the extent to which physical activity among adolescent female friends is interdependent. The participants were 318 adolescent girls with a mean age of 16.0 years (range: 15-18 years). Pedometry was used to assess physical activity over 4 days. The relationship between an individual girl and her…

The purpose of this study was to determine to what degree collective efficacy judgments based on summative team performance capabilities exhibited different levels of prediction for three additive intervals of team performance in women's ice hockey. Collective efficacy beliefs of 12 teams were assessed prior to Friday's game and Saturday's game…

The results of a functional analysis of problem behavior and a paired-choice assessment were compared to determine whether the same social reinforcers were identified for problem behavior and an appropriate response (time allocation). The two assessments were conducted in classroom settings with 4 adolescents with mental retardation who engaged in…

Monitoring the Future (MTF), now in its 35th year, has become one of the nation's most relied-upon sources of information on changes taking place in licit and illicit psychoactive drug use among American adolescents, college students, young adults, and more recently, middle-aged adults. During the last three and a half decades, the study has…

The purpose of this study was to investigate the relationship between time-related variables of the physical education lesson and skill concepts acquisition and retention. One hundred and four students aged 6.4 to 7.9 years, and their six physical educators participated. The motor behavior of thirty-six selected students was videotaped during a…

The 4-1-4 or the interim term is used by an increasing number of colleges and universities in an effort to enrich or rejuvenate their educational program by providing a special new kind of learning experience for the entire college community. Generally a brief period between semesters or quarters, the interim term can take several forms: (1) it…

Conclusion is that it is not necessary to record the behavior of every pupil or an entire class in order to adequately measure a specific dimension of the classroom. Rather, observational efficiency can be attained through the utilization of sampling procedures for a given type of classroom situation. (Authors)

Objective of this study was to determine subjects' reliability in rating randomly played ascending and descending melodic intervals within the octave on the basis of their familiarity with each type of interval and the frequency of their having experienced each type of interval in music. (Author/CB)

Vocal pitch acuity on ascending intervals is highly superior to acuity on the same descending intervals. (Author)

The time judgments of the older participants were significantly and systematically determined by a metronome rate. Results are consistent with the notion of increased field-dependence among older persons and suggest that their greater social conformity and their inability to ignore irrelevant stimuli might also be explicable.

Vocal activity in spontaneous speech appears to alternate between regular periods of high and low activity. These cycles may be properties of social systems, internal cognitive rhythms, or physiological rhythms that affect readiness to initiate activity. (Author/RL)

The generality of the molar view of behavior was extended to the study of choice with rats, showing the usefulness of studying order at various levels of extendedness. Rats' presses on two levers produced food according to concurrent variable-interval variable-interval schedules. Seven different reinforcer ratios were arranged within each session,…
