Can Observing Behavior Predict Performance in Conditional Discriminations?

Description: Prompts are implemented often in training procedures, to include conditional discriminations, and this can lead to prompt dependency. The current study extends a prior study that suggested that the effectiveness of supplementary visual stimuli displaying the sample and comparison was dependent on the timing in relation to the selection task, presented as a prompt or feedback, in a match-to-sample procedure. The current research examines if the differences in that effectiveness were due to differences in observing behavior in those two conditions. Measures of observing behavior were determined by making access to the individual visual stimuli contingent on clicking on the visual stimulus and keeping the cursor located on the stimulus. Participants viewed the sample comparison much less than the comparison stimulus in both the prompt and feedback conditions. Latency to select the comparison stimulus was much shorter for the prompt condition suggesting that the participants might have interacted differently with the selection task in the two conditions.

Reinforcing Variability Produces Stereotypic Behavior

Description: Behaving in novel ways is essential to the development of the types of complex performances described by the term creativity, problem solving, and perseverance. Some research suggests that response variability is an operant and a critical component of novel behavior. However, other account of novel behavior may be more parsimonious. Topographical variability has rarely been examined, nor has operant variability with organisms with baselines featuring stereotypic responding. This study examined the effects of a variability-specifying contingency on the cumulative novel responses of undergraduate students. Using the PORTL apparatus, participants interacted with a ball with a single hand. When the variability-specifying contingency was in effect, novel topographies were reinforced. When a reinforce every response condition was implemented, the participants did not emit any novel responses. When variability-specifying contingencies were in effect, novel responses were rarely followed by subsequent novel responses. They were mostly followed by repeated emission of the same topography, or by other previously emitted topographies. Novel responding did not persist long, although the variability-specifying contingency remained in effect and the potential for novel responding was great. The variability-specifying contingency often resulted in stereotypic response chains. Each of these findings call into the question the assertion that variability is an operant and suggests other possible explanations for the observed novelty.

Teaching Behavior Professionals to Use the Interview-Informed Synthesized Contingency Analysis (IISCA): A Preliminary Investigation

Description: We assessed the implementation accuracy and fidelity of two board certified behavior analysts (BCBAs) using the open-ended interview from Hanley. Participants interviewed a confederate using the open-ended interview, and were then asked to use information gathered from the interview to create operational definitions of target behaviors as well as test and control condition procedures for a subsequent matched test-control functional analysis as is characteristic of the interview-informed synthesized contingency analysis (IISCA) strategy. Brief behavioral skills training (BST) was then implemented with all participants to increase the accuracy of constructing both target behavior definitions and functional analysis procedures. Preliminary results show moderate rates of accuracy of target behavior definitions and functional analysis procedures prior to BST, and high rates of accuracy following BST. The results also suggest high implementation fidelity on the open-ended interview may not be necessary to achieve high accuracy when constructing target behavior definitions and functional analysis procedures.
