Research directed toward maltreated children possesses an urgency characteristic of all problems of great social import. Child maltreatment sets in motion a probabilistic path that is characterized by failure in the successful resolution of major stage-salient issues of development. These developmental disruptions contribute to a profile of…

A simple prompting procedure involving index cards was used to increase suggestive selling by the owner/operator of a small pet grooming business. Over a year of baseline data revealed that no sales prompts were given and few pet products were sold. When the owner was prompted by an index card to ask customers if they wanted to purchase pet…

Rex Stockton reflects on group work as it was during his early career in the 1960s and 1970s and as it is today. He comments on his service to the group work field, his research on feedback exchange and leader training, and future trends and directions in group work. Additionally, he discusses some of his interests and contributions outside of the…

In this article I reply to a comment made by S. J. Guastello on my original article, "The Cinderella of Psychology: The Neglect of Motor Control in the Science of Mental Life and Behavior." In my article, I asked why motor control has received short shrift in psychology. I observed that it is ironic that motor control has long had the status of a…

The authors address the methodological, theoretical, and ideological criticisms of their article on adolescent perceptions of parenting behavior made by G. Greenberg and T. Partridge. Behavioral genetic methods have provided unique insights on the origins of individual differences in behavior and, when applied to parenting and other putative…

The idea of visual complexity, the history of its measurement, and its implications for behavior are reviewed, starting with structuralism and Gestalt psychology at the beginning of the 20th century and ending with visual complexity theory, perceptual learning theory, and neural circuit theory at the beginning of the 21st. Evidence is drawn from…

Roger Barker, influenced by Lewin, developed a powerful theory in psychology, behavior setting theory. Paradoxically, this theory is still not widely known or understood in mainstream American psychology. Oral histories of the core group who worked with Barker were collected and examined to determine influences on them and subsequent directions in…

Previous studies of the Stroop task propose two key mediators: the prefrontal and cingulate cortices but hints exist of functional specialization within these regions. This study aimed to examine the effect of task modality upon the prefrontal and cingulate response by examining the response to colour, number, and shape Stroop tasks whilst BOLD…

In the past two decades, positive behavior support (PBS) has emerged from applied behavior analysis (ABA) as a newly fashioned approach to problems of behavioral adaptation. ABA was established in the 1960s as a science in which learning principles are systematically applied to produce socially important changes in behavior, whereas PBS was…

An international movement has focused on identifying evidence-based interventions that were developed to change psychological constructs and that are supported by controlled studies. However, inconsistent findings within individual intervention studies and among multiple studies raise critical problems in interpreting the evidence, and deciding…

Three pigeons were trained to discriminate among 5 mg/kg pentobarbital, 2 mg/kg amphetamine, a combination of these two drugs at these doses, and saline using a four-choice procedure (amphetamine--pentobarbital group). Three other pigeons were trained to discriminate among 5 mg/kg morphine, 2 mg/kg methamphetamine, a combination of these two drugs…

Pigeons' choosing between fixed-interval and random-interval schedules of reinforcement was investigated in three experiments using a discrete-trial procedure. In all three experiments, the random-interval schedule was generated by sampling a probability distribution at an interval (and in multiples of the interval) equal to that of the…

Our research addressed the question of whether sensitivity to relative reinforcer magnitude in concurrent chains depends on the distribution of reinforcer delays when the terminal-link schedules are equal. In Experiment 1, 12 pigeons responded in a two-component procedure. In both components, the initial links were concurrent variable-interval 40…

The present experiment investigated whether rats formed emergent, untrained stimulus relations in many-to-one matching-to-sample discriminations. In Phase 1, rats were trained to match two samples (triangle and horizontal stripes) to a common comparison (horizontal stripes) and two additional samples (circle or vertical stripes) to another…

We examined women's participation, relative to men's, at the annual meetings of the Association for Behavior Analysis (ABA) between 1975 and 2005. Among our findings are upward trends in female presenters across formats (e.g., posters), types of authorship (e.g., first authors), and specialty areas (e.g., autism). Where women have attained…
