Conditional Discriminations and Derived Relations: Pinpointing the Moment of Emergence

Description: Four subjects were exposed to the four trial types that define stimulus equivalence from the beginning of the experiment. Procedures were designed to identify acquisition dynamics and relate these observations to responding indicative of equivalence class formation. The data show that, for all subjects, the acquisition of training conditional discriminations was correlated with systematic changes in the subjects' selection responses. The results also indicate that the traditional percent correc… more

The Effects of a Point Loss Contingency on Equivalence

Description: The effects of point loss for symmetrical probe performances on other performances of an observed equivalence class, on the emergence of equivalence performances, and on performances in other contexts were examined. After training six conditional discriminations in three contexts, probes (symmetry, transitivity, symmetrical transitivity) were introduced in contexts 1 and 2. In context 3, only trained conditional discrimination trials were delivered. After demonstrations of equivalence in contex… more

The Evocative and Repertoire-Altering Effects of Contingency-Specifying Stimuli

Description: The effects of deadlines in contingency-specifying stimuli among nine 4 to 5 year old children were investigated. Each child was given verbal statements differing in the specified deadline, the delivery of the reinforcer, and the opportunity to respond. The results indicated: (a) statements not specifying deadlines or reinforcers failed to control the children's behavior reliably, (b) specifying deadlines, either immediate or delayed, and immediate reinforcers exerted reliable control over the … more

An Experimental Analysis of Preference Problems in a Self-Control Choice Procedure by Adults with Mental Retardation

Description: The original purpose of this study was to determine if Tegretol has an effect on the impulsive behavior exhibited by people with mental retardation. This was to be accomplished through a replication of the self-control choice procedures used by Ragotzy, Blakely, and Poling (1988). The procedure involved three stages. First, subjects chose between stimuli that provided either one or three edibles. Then the stimuli associated with the smaller and larger edibles were reversed. Following this, the … more

The Function-Altering Effects of Contingency-Specifying Stimuli

Description: Three children between the ages of 3 and 3 1/2 were asked to choose a colored object from an array of 5 colors in a baseline condition. After color preferences were established, stickers, small toys and praise were made contingent on choosing the least preferred color. After the first experimental condition resulted in consistent choosing of the least preferred color, a second experimental condition was implemented. At the beginning of each session a contingency-specifying stimulus (CSS) was pr… more

The Physiological Control of Verbal Behavior

Description: The current study sought to investigate whether physiological responses, such as the electrodermographic response (EDG) and/or the frontalis muscle electrical potential (EMG) could be developed as a source of control over verbal responses. Discrimination training procedures using points exchangeable for money were employed to condition verbal responses occasioned by minute interoceptive events with 2 adult human subjects. Specific verbal responses were reinforced in the presence of changes in E… more
