Data on numerical processing by verbal (human) and non-verbal (animal and human)
subjects are integrated by the hypothesis that a non-verbal counting process represents …

The contributions of cortico-cerebellar and cortico-striatal circuits to timing and time
perception have often been a point of contention. In this review we propose that the …

A fundamental question in cognitive science is whether animals can represent numerosity (a
property of a stimulus that is defined by the number of discriminable elements it contains) …

Animal Learning and Cognition: An Introduction provides an up-to-date review of the
principal findings from more than a century of research into animal intelligence. This new …

Three rhesus monkeys (Macaca mulatta) were trained to respond to exemplars of 1, 2, 3,
and 4 in an ascending, descending, or a nonmonotonic numerical order (1→ 2→ 3→ 4, 4→ …

This paper briefly outlines theories dealing with attentional processes, before the status of
attention is evaluated within cognitive models of psychological time. Particular emphasis is …

The existence of a possible common mechanism for duration and numerosity processing
was tested with a Stroop task. Participants had to compare either the duration or the …

Although many animal species can represent numerical values, little is known about how
salient number is relative to other object properties for nonhuman animals. In one …

Time perception is important for many aspects of human behavior, and a large literature
documents that adults represent intervals and that their ability to discriminate temporal …

Background Research on human infants, mammals, birds and fish has demonstrated that
rudimentary numerical abilities pre-date the evolution of human language. Yet there is …
