Schnall, S., & Gattis, M. (1998). Transitive Inference by Visual Reasoning.
Abstract: Two experiments are reported that investigated the influence
of linear spatial organization on transitive inference
performance. Reward/no-reward relations between
overlapping pairs of elements were presented in a context of
linear spatial order or random spatial order. Participants in
the linear arrangement condition showed evidence for visual
reasoning: They systematically mapped spatial relations to
conceptual relation and used the spatial relations to make
inferences on a reasoning task in a new spatial context. We
suggest that linear ordering may be a “good figure”, by
constituting a parsimonious representation for the integration
of premises, as well as for the inferencing process. The late
emergence of transitive inference in children may be the
result of limited cognitive capacity, which --unless an
external spatial array is available --constrains the
construction of an internal spatial array.

Abstract: The Way to Perfect Horsemanship is an outstanding work in the vast literature devoted to horsemanship. It provides, for the first time, a clear insight into the psychological makeup of the horse, its muscular system, the mechanics of its movement, and the aids to human-to-horse communication. Udo Burger presents his philosophy of riding in a scientific manner, asserting that no one can no more learn to ride without a knowledge of horse physiology and psychology than one can learn the art of medecine without a background in health and disease. He clearly explains what one should feel and do on horseback--ultimately, as if one is part of the horse, completely united with it in all of its movements. Anyone with a genuine empathy for horses--wether teacher, trainer, competitor, or occasional rider--will benefit enormously from reading this classic work on horsemanship. The late Udo Burger was an accomplished horseman and one of Germany's most esteemed equine veterinarians.

Abstract: Summary The last 20-30 years have seen two `scientific revolutions' in the study of animal behavior: the cognitive revolution that originated in psychology, and the Darwinian, behavioral ecology revolution that originated in biology. Among psychologists, the cognitive revolution has had enormous impact. Similarly, among biologists, the Darwinian revolution has had enormous impact. The major theme of this chapter is that these two scientific research programs need to be combined into a single approach, simultaneously cognitive and Darwinian, and that this single approach is most appropriately called cognitive ethology.
