Path integration in dogs

Article Abstract:

Path integration in Canis familiaris needed to return to the starting location of L-shaped outward paths without landmark data was studied. An investigation of the distributions of errors in the return direction and distance indicated that the dogs committed both systematic and random errors. A path integration model which the dog overestimates slightly the inferred motion parallax of the starting point was able to provide a rough approximation of the errors.

The role of the biological clock in the sum compass orientation of free-running individuals of Talitrus saltator

Article Abstract:

Variable-drift paradigm is used to investigate the relation between the angle of solar orientation and the circadian rhythm of locomotor activity in Talitrus saltator. The sun orientation angles were strongly dependent on time of day, suggesting that orientation and locomotor activity are regulated by the same time-keeping system.

Blindfolded dogs relocate a target through path integration

Article Abstract:

The blindfolded dog's relocation of the briefly presented food target after having been led away from it, by relying on feedback information from locomotion (path integration), was investigated. Many functional implications of the path integration on hunting are discussed.
