Speed analysis of stimulus equivalence
Article Abstract:
Significant variations in accuracy across nodal distance and trial type are found in the first test of equivalence when testing the speed of college students' accurate response to 18 conditional relations. While speed differences are significant even after extending the test, response speed is inversely related to the number of nodes. Variations in response speed are found across all trial types, except in transitivity and combined trials. No major variations are noticed when an instructed group, a queried group, and a standard group are tested to study the generality of these comparisons.

Avoidance of 20% carbon dioxide-enriched air with humans
Article Abstract:
A Sidman avoidance procedure was used to determine whether avoidance behavior in humans can be induced using carbon dioxide (CO2) presentation as aversive stimuli in laboratory experiments. Previous studies confirm that CO2 presentation produce physiological reactions similar to anxiety-related behavior. Operant responding and self-report ratings of fear were used to determine the aversive properties of CO2. It was found that 25-s inhalations of 20% CO2 can effectively serve aversive stimuli of anxiety in laboratory conditions.
