AbstractCollege student members of Greek Letter Organizations (GLOs) report high levels of alcohol consumption, which is associated with adverse academic and health consequences. Those who report lower consumption also report counting their drinks, which requires the ability to identify and pour standard servings of alcohol, skills college students generally lack. Behavioral skills training (BST) has been used to teach students to pour standard servings of beer. However, little is known about whether BST is effective when used in a small‐group format or with other alcohol types, and whether skills generalize across time and novel cups. We used a nonconcurrent multiple baseline design to address these gaps. After receiving small group BST, all participants poured beer accurately, most poured accurately at follow‐up, and about half poured accurately into a novel cup. After receiving individual BST, participants' pours of liquor were variable and most required additional training.

In 1948, Skinner described the behavior of pigeons under response‐independent schedules as “superstitious,” and proposed that the responses were reinforced by contiguous, adventitious food deliveries. Subsequently, response‐independent schedules have been of interest to both basic and applied researchers, first to understand the mechanisms involved, and later, as “noncontingent reinforcement” (NCR) to reduce undesirable behavior. However, the potential superstitious effects produced by these schedules have been challenged, with some researchers arguing that antecedent variables play a significant role. This paper examines the evidence for adventitious reinforcement from both laboratory and applied research, the results of which suggest that antecedent, nonoperant functions may be important in fully understanding the effects of NCR. We propose an applied‐basic research synthesis, in which attention to potential nonoperant functions could provide a more complete understanding of response‐independent schedules. We conclude with a summary of the applied implications of the nonoperant functions of NCR schedules.

AbstractPica is a life threating form of challenging behavior displayed by individuals with intellectual and developmental disabilities. In most cases, pica is maintained by automatic reinforcement. Common interventions for pica use some combination of response blocking, response interruption and redirection (RIRD), differential reinforcement of alternative behavior (DRA), and noncontingent reinforcement with competing stimuli. However, there is need for additional research regarding DRA procedures that emphasize skills acquisition by teaching alternative behaviors that modify the established behavioral chain of pica responses that occur in the presence of non‐edible stimuli. There is also a need to examine the generality of recent advances in competing stimulus assessment (CSA) methodologies—namely, the augmented‐CSA (A‐CSA)—to pica. Thus, the purpose of the present investigation was to systematically replicate and extend previous research for the assessment and treatment of pica in an individual with IDD. First, we conducted a functional analysis to identify environmental variables associated with pica. Next, taught Patrick a differential response (i.e., discard pica items in trash receptacle) to earn reinforcers in conjunction with a RIRD procedure. Finally, we conducted an A‐CSA for pica. Overall, low rates of pica were maintained over time with a combination of these procedures, and treatment was generalized across settings and people.
