Experimental control of nodality via equal presentations of conditional discriminations in different equivalence protocols under speed and no-speed conditions

Article Abstract:

A within-participant comparison of simple-to-complex, complex-to-simple, and simultaneous protocols was conducted establishing different sets of three 7-member equivalence classes for 4 undergraduate students. The results challenge the nodality effect and the notion of relatedness of equivalence-class members, and support a reinforcement-contingency, instead of a structural, perspective on equivalence-class formation.

Stock optimizing in choice when a token deposit is the operant

Article Abstract:

Experiments with 2 monkeys who earned their daily food rations by depositing tokens into one of two slots are conducted. Results suggest that reinforcer stock is distinct from reinforcer flow and the monkeys are capable of maximizing the former at the expense of the latter.

Tests of behavioral-economic assessments of relative reinforcer efficacy II: economic complements

Article Abstract:

The study examines the predictions of two behavioral-economic approaches to quantify relative reinforcer efficacy. The results conclude that the predictions of the normalized demand analysis were more useful as a measure than non-normalized demand analysis.
