An operant conditioning discrimination paradigm was evaluated in terms of relationships between response behavior of young children and two stimulus components of the paradigm, the discriminative stimulus (DS) and the reinforcing stimulus (RS). Experiment I measured response performance in normal 1-year-old subjects as a function of differences in intensity and/or complexity among three DSs. Results showed no significant differences in conditioning rate, habituation, or consistency of the conditioned response relative to variable properties of the DS. Experiment II examined response performance of normal 2-year-old children as a function of two modifications in the RS, reinforcement schedule and reinforcement novelty. Subjects reinforced on a variable-ratio schedule of intermittent reinforcement and subjects reinforced on a 100% schedule demonstrated equivalent response habituation and consistency. In the second part of the experiment, subjects receiving novel RSs showed significantly greater response recovery than subjects reinforced with familiar RSs. Comparison of normal 1- and 2-year-old children revealed similar rates of conditioning and response consistency. However, 2-year-olds habituated more rapidly than 1-year-olds.

Abstract Political psychology and social constructivism exist in an “ideational alliance” against realism; however, both have overlooked behavioral conditioning, the basis of animal learning. Through six stages situated in international negotiation behaviors, the theory of Conditioning Constructs shows how behavioral conditioning can take parties from specific to diffuse reciprocity, rationalist to constructivist cooperation, and crisis to durable peace. In stages 1, 2 and 3, parties use negotiated agreements to exit prisoner’s dilemmas, continuously reinforce cooperation during agreement implementation, and satiate to rewards as initial implementation finalizes. In stages 4, 5 and 6, parties receive fresh rewards with new negotiations, undergo intermittent reinforcement with periodic agreements thereafter, and finally attribute cooperative behavior to actor constructs. Conditioning Constructs demonstrates that agency is possible in socially constructed structures through willful participation in conditioning through negotiation; and that, while Anatol Rapoport’s tit-for-tat strategy is suited to initial cooperation, intermittent reinforcement better preserves late-stage cooperation.

The human eye is insensitive to the angular direction of the light e-vector, but several animal species have the ability to discriminate differently polarized lights. How the polarization is detected is often unclear, however. Egg-laying Papilio butterflies have been shown to see false colours when presented with differently polarized lights. Here we asked whether this also holds in foraging butterflies. After training individuals to feed on nectar in front of an unpolarized spectral light, we carried out three dual-choice tests, where the discrimination of (i) the spectral content, (ii) the light intensity, and (iii) the e-vector orientation were investigated. In the first test, the butterflies selected the trained spectrum irrespective of its intensity, and in the second test they chose the light with the higher intensity. The result of the e-vector discrimination test was very similar to that of the second test, suggesting that foraging butterflies discriminate differently polarized lights as differing in brightness rather than as differing in colour. Papilio butterflies are clearly able to use at least two modes of polarization vision depending on the behavioural context.
