In real-life decision environments people learn from their direct experience with alternative courses of action. Yet they can accelerate their learning by using functional knowledge about the features characterizing the alternatives. We designed a novel contextual multi-armed bandit task where decision makers chose repeatedly between multiple alternatives characterized by two informative featur...

Eight young children who displayed destructive behavior maintained, at least in part, by negative reinforcement received long-term functional communication training (FCT). During FCT, the children completed a portion of a task and then touched a communication card attached to a microswitch to obtain brief breaks. Prior to and intermittently throughout FCT, extinction probes were conducted withi...

Wandering behavior of 4 geriatric patients with dementia residing in a long-term care facility was assessed using direct behavioral observations. The consequences identified during the observations as maintaining wandering for each patient were then applied for the absence of wandering using differential reinforcement of other behavior (DRO). The effectiveness of the DRO procedure was evaluated...

Social skills deficits are a defining feature of individuals diagnosed with autism and other pervasive developmental disorders (PDD), which can impair functioning and put the individual at higher risk for developing problem behavior (e.g., self-injury, aggression). In the current study, an adolescent with PDD displayed inappropriate social behavior (inappropriate comments, social withdrawal, an...

Pica is a life-threatening behavior displayed by many individuals with developmental disabilities. In the current study, automatic reinforcement maintained the pica of 3 participants. Following functional analyses of pica, response-effort manipulations were conducted in which the effort to obtain pica or alternative items was varied systematically. Several general relations emerged as a result ...

Recent research has emphasized the importance of manipulating antecedent variables to reduce interfering behaviors when teaching persons with autism. Few studies have focused on the effects of the rate of teacher-presented instructional demands as an independent variable. In this study, an alternating treatment design was used to evaluate the effects of varied rates of teacher-presented demands...

during the past two decades, the use of bioplastics as an alternative to regular plastics has received much attention in many different industries. the mechanical and degradable properties of bioplastic are important for their utilization. in this research cellulose of wheat straw and glycerol were mixed by different weight ratios and then reinforced by using date palm fibers. to prepare the bi...

We examined how positive and negative reinforcement influenced time allocation, occurrence of problem behavior, and completion of parent instructions during a concurrent choice assessment with 2 preschool-aged children who displayed severe problem behavior in their homes. The children were given a series of concurrent choice options that varied availability of parent attention, access to prefer...
