Considerable evidence has demonstrated a critical role for the nucleus accumbens (NAc) in the acquisition and flexibility of behavioral strategies. These processes are guided by the activity of two discrete neuron types, dopamine D1- or D2-receptor expressing medium spiny neurons (D1-/D2-MSNs). Here we used the IntelliCage, an automated…

Descriptive assessments involve recording naturally occurring instances of behavior and corresponding antecedent and consequent events. Authors have argued for the use of two forms of descriptive assessment, structured and narrative Antecedent-Behavior-Consequence recording, because these methods may require little training. However, the extent to…

Activity schedules, guided compliance, and differential reinforcement are often used to reduce transition-related problem behavior in children with autism. One potential way to increase the effectiveness of these procedures when transitioning children from preferred to nonpreferred activities is to alter the motivating operations for…

The problem of demonstrative behavior is very topical among teenagers and this issue has become the subject of systematic scientific research. Demonstrative manifestations in adolescents disrupt the favorable socialization; therefore, understanding, prevention and correction of demonstrative behavior at this age is relevant and requires special…

In two experimental and exploratory studies, we wanted to test the differentiated effects on preschoolers with externalizing behavior (EB) of two short-term social information processing (SIP) and Theory of Mind (ToM) training sessions, in comparison with typically developing (TD) preschoolers or with preschoolers with EB whom didn't receive…

The purpose of this study was to investigate whether there would be a change in preservice teachers' (a) confidence concerning the resolution of behavior problems, (b) tactics for resolving them, (c) anticipation of problems, (d) fears about management issues, and (e) confidence in methodology and pedagogy over the time period of a one-semester…

We examined independent and interactive associations linking preadolescents' socially anxious feelings and peer victimization experiences with their social behaviors (rated by parents and teachers) and psychophysiological arousal during lab simulations of salient peer stress situations in preadolescence (peer evaluation and peer rebuff).…

We evaluated interrater agreement across multiple respondents on anecdotal assessments and compared cases in which agreement was obtained with outcomes of functional analyses. Experiment 1 evaluated agreement among multiple respondents on the function of problem behavior for 27 individuals across 42 target behaviors using the Motivation Assessment…

The aim of the "Tools of the Mind" prekindergarten curriculum is to enhance children's executive function skills within an instructional context that promotes the basic academic and social skills that prepare them for kindergarten and beyond. To investigate the effectiveness of "Tools" in achieving this aim, the authors are…

A series of experiments on operant variability by Neuringer and colleagues (e.g., Neuringer, 1986, 2002; Page & Neuringer, 1985) have been repeatedly cited as showing that behavioral variability can be reinforced by making reinforcement contingent on it. They showed that the degree of variability in pigeons' eight-peck sequences, as measured by U…

This single-case-design experiment examined an intervention to decrease bed-sharing in children, ages 2 through 6. Three sessions were conducted with each parent. At the first session, parents described bed-sharing history and began collecting baseline data. At the second session, parents were instructed to employ the intervention. At the third…

Dependent variables in research on problem behavior typically are based on measures of response repetition, but these measures may be problematic when behavior poses high risk or when its occurrence terminates a session. We examined response latency as the index of behavior during assessment. In Experiment 1, we compared response rate and latency…

When researchers use the term "mind wandering" for task-unrelated thoughts in signal detection tasks, we may fall into the trap of believing that spontaneous thoughts are task unrelated in a deeper sense. Similar negative connotations are attached to common terms like "cognitive failures", "resting state", "rumination", "distraction", "attentional…

We evaluated the effects of presession satiation on challenging behavior and academic engagement during subsequent classroom activities for three 5-6 year-old children with autism. The percentage of 10-s intervals with challenging behavior and academic engagement during 20-min classroom activity sessions was observed under two conditions. One…

This study examines prevention system transformation as part of a community-randomized controlled trial of Communities That Care (CTC). Using data from surveys of community leaders, we examine differences between CTC and control communities 4.5 years after CTC implementation. Significantly higher levels of adopting a science-based approach to…
