Recent work in animal cognition has focused on how animals respond to new or changing
environments. Although many species are currently in decline, other species are thriving in …

Invariant visual object recognition is the ability to recognize visual objects despite the vastly
different images that each object can project onto the retina during natural vision, depending …

The science of animal consciousness investigates (i) which animal species are conscious
(the distribution question) and (ii) how conscious experience differs in detail between …

Visual categorization of complex, natural stimuli has been studied for some time in human
and nonhuman primates. Recent interest in the rodent as a model for visual perception …

A prominent theory of category learning, COVIS, posits that new categories are learned with
either a declarative or procedural system, depending on the task. The declarative system …

Behavioral studies of object recognition in pigeons have been conducted for 50 years,
yielding a large body of data. Recent work has been directed toward synthesizing this …

Categorization is a fundamental cognitive function that organizes our experiences into
meaningful “chunks.” This category knowledge can then be generalized to novel stimuli and …

Previous studies showed that the anterior cingulate cortex (ACC) plays a role in selective
visual attention. The current study further examined the role of the ACC in attention using a …

Despite their growing popularity as models of visual functions, it remains unclear whether
rodents are capable of deploying advanced shape-processing strategies when engaged in …

The hippocampus may play a role in categorization because of the need to differentiate
stimulus categories (pattern separation) and to recognize category membership of stimuli …
