Animal coloration patterns, from zebra stripes to bird egg speckles, are remarkably varied.
With research on the perception, function, and evolution of animal patterns growing rapidly …

Birds have acute vision and many remarkable visual cognition abilities, due to their unique
living environment. The underlying neural mechanisms have also attracted interests of …

It has been argued that humans' susceptibility to visual illusions does not simply reflect
cognitive flaws but rather specific functional adaptations of our perceptual system. The data …

Extensive research has documented evidence for rule learning in sequential behavior tasks
in both rats and humans. We adapted the 2-choice serial multiple choice (SMC) task …

Optical illusions have long been used in behavioural studies to investigate the perceptual
mechanisms underlying vision in animals. So far, three studies have focused on ungulates …

Dogs enrolled in a previous study were assessed two years later for reliability of their
local/global preference in a discrimination test with the same hierarchical stimuli used in the …

The biological mechanisms used to categorize and recognize behaviors are poorly
understood in both human and non-human animals. Using animated digital models, we …

Whether animals experience visual illusions is a fertile area of study for examining the
evolution and operation of visual cognition across different species. Here, five starlings were …

Detecting global patterns in the environment is essential to object perception and
recognition. Consistent with this, pigeons have been shown to readily detect and locate …

An important challenge for animal and artificial visual systems is separating the system's
own motions from the movements of other animals or events. To examine this issue in birds …
