This study asked whether the concurrent reinforcement of behavioral variability facilitates learning to emit a difficult target response. Sixty students repeatedly pressed sequences of keys, with an originally infrequently occurring target sequence consistently being followed by positive feedback. Three conditions differed in the feedback given to…

Covert sensitization is the first of a family of behavior therapy procedures called covert conditioning initially developed by Joseph Cautela in the 1960s and 1970s. The covert conditioning procedures involve the use of visualized imagery and are designed to work according to operant conditioning principles. When working with cooperative clients…

The present study undertook an updated citation analysis of Skinner's (1957) "Verbal Behavior". All articles that cited "Verbal Behavior" between 1984 and 2004 were recorded and content analyzed into one of five categories; four empirical and one nonempirical. Of the empirical categories, studies that employed a verbal operant from Skinner's…

The main argument being presented in this paper is that instructional designers and educational researchers need to shift their attention from performance to interest. Educational digital games have to aim at building lasting interest in real world applications. The main hypothesis advocated in this paper is that the use of rewards in educational…

Two experiments examined pigeons' postponement of a signaled extinction period, or timeout (TO), from an ongoing schedule of response-dependent food delivery. A concurrent-operant procedure was used in which responses on one (food) key produced food according to a variable-interval schedule and responses on a second (postponement) key delayed the…

Skinner's conceptual analysis of language has influenced one model of early and intensive behavioral intervention with children, which incorporates verbal operants including mands, tacts, intraverbals, etc. Many studies have examined the mand and tact relations, with little focus on teaching intraverbal behavior. In the present experiment,…

Findings from a study investigating the conditions under which contingency learning games were associated with optimal child and adult concomitant and social--emotional behavior benefits are reported. Participants were 41 preschool children with multiple disabilities and profound developmental delays and their parents or teachers. Results showed…

Although experimental analysis methodologies have been useful for identifying the function of a wide variety of target behaviors (e.g., Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994), only recently have such procedures been applied to verbal operants (Lerman et al., 2005). In the current study, we conducted a systematic replication of the…

Background: Response-contingent time-out has been shown to be an effective technique for enhancing fluency in people who stutter. However, the factors that determine individual responsiveness to time-out are not well understood. Aims: The study investigated the effectiveness of using response-contingent time-out to reduce stuttering frequency in…

This paper proposes that an organism's integrated repertoire of operant behavior has the status of a biological system, similar to other biological systems, like the nervous, cardiovascular, or immune systems. Evidence from a number of sources indicates that the distinctions between biological and behavioral events is often misleading, engendering…

Few studies have made use of B. F. Skinner's (1957) behavioral analysis of language and precise taxonomy of verbal behavior when describing the controlling variables for the mand relation. Consequently, the motivating operation (MO) has not typically been identified as an independent variable and the nature of a spontaneous mand has been…

When neural events are analyzed as stimuli and responses, functional relations among them and among overt stimuli and responses can be unveiled. The integration of neuroscience and the experimental analysis of behavior is beginning to provide empirical evidence of involvement of neural events in the three-term contingency relating discriminative…

Using 130 rural, culturally deprived slow learning children, group operant and individual operant techniques were compared in classrooms of normal size. (Editor)

The behavioral processes through which people react appropriately to verbal descriptions remain poorly understood. I argue here that these processes are Pavlovian. Common objections to a Pavlovian account of symbolic behavior evidence a lack of familiarity with the relevant data or misunderstandings of operant theory. Although much remains to be…
