Spiders, having minute brains, were once considered simple, instinct-driven automatons, but
research on spider biology is revealing increasing evidence of their cognitive abilities. In this …

Animal researchers commonly present pictures to their subjects, usually birds or monkeys, in
order to infer how natural objects are perceived and conceptualised, or to discover the brain …

We compared the responses of the nesting red-backed shrikes (Lanius collurio) to three
dummies of a common nest predator, the Eurasian jay (Garrulus glandarius), each made …

This paper examines the way birds and nonhuman primates process pictures of objects.
After having defined three main modes of picture perception that might occur in animals …

Priming, a change in the mental processing of a stimulus as a result of prior encounter with a
related stimulus, has been observed repeatedly and studied extensively in humans. Yet …

Humans show visual perceptual priming by identifying degraded images faster and more
accurately if they have seen the original images, while simultaneously failing to recognize …

Picture perception in birds was examined from four points of view: correlation, interaction,
distortion, and transfer. The main question raised was whether they have the cognitive ability …

Mathematical principles of reinforcement were developed in order to (1) account for the
interaction of target responding and other behavior;(2) provide a simple graphical …

In humans, it has been established that conscious retrieval of previously viewed stimuli is
enhanced by deeper levels of processing, with deeper levels referring to meaningful …
