The State of Teaching Philosophy in Behavior Analysis Training Programs.

Professional organizations that oversee the accreditation of graduate training programs in behavior analysis have increased didactic training requirements for programs in various domains across the years. One of the areas in which this has occurred concerns training in philosophy within behavior science. Although content-hour requirements for didactic philosophical training have increased, the contents of this training are not prescribed and are left to the discretion of individual programs. We conducted a survey of verified course sequence programs to assess the current state of training in philosophy in behavior analysis graduate training programs. The results provided a list of common topics and readings in philosophy courses, and indicated an emphasis on radical behaviorism and the works of B. F. Skinner. The list of topics and readings obtained provides a resource for course design, and we suggest that exposing students to a broader range of behavioristic and nonbehavioristic topics and readings may enhance students' orientation to philosophical issues in behavior analysis.

A preliminary evaluation of habituation and dishabituation of operant responding in mice.

Previous research has suggested that operant response decrements within experimental sessions are due in part to habituation to the repeated presentation of reinforcers. One way to assess the role of habituation in within-session response decrements is to conduct a test for dishabituation, a phenomenon in which a habituated response to a given stimulus recovers following the presentation of some strong or novel stimulus other than the habituated stimulus. Dishabituation of operant responding has been demonstrated on several occasions in the literature, but studies with non-human subjects have thus far been limited to those using rats and pigeons. Two experiments attempting to replicate these findings with mice were conducted. Two groups of mice nose-poked for a sweetened condensed milk/water reinforcer on either a fixed-ratio 4 or variable-interval 15 s schedule of reinforcement. During testing, baseline sessions were then alternated with two test conditions and a control condition. Test conditions included a 5 s auditory stimulus or flashing of the house light presented mid-session. Control conditions were identical to baseline. Dishabituation was not observed for either group in Experiment 1. In Experiment 2, dishabituation was not observed for the fixed-ratio 4 group but was observed for the variable interval 15 s group. Considerations for further study of operant dishabituation in mice are discussed.
