Research on a growing number of vertebrate species has shown that the left and right sides
of the brain process information in different ways and that lateralized brain function is …

Laterality, best understood as asymmetries of bilateral structures or biases in behaviour, has
been demonstrated in species from all major vertebrate classes, and in many invertebrates …

Our goal in this chapter is to provide a concise introduction to the study of left–right
asymmetries in brain and behavior from a comparative perspective. We consider evidence …

Lateralization is widespread throughout the animal kingdom [1–7] and can increase task
efficiency via shortening reaction times and saving on neural tissue [8–16]. However …

To study the fitness effects of individual variation in cognitive traits, it is paramount to
understand whether traits such as personality and physiological stress influence cognitive …

Highlights•Many animals are lateralized and exhibit a consistent turning bias.•We examined
the cost/benefits of this trait in damselfish.•Lateralization enhanced predator learning but …

Individual animals vary in their behaviour and reactions to novel situations. These
differences may extend to differences in cognition among individuals. We tested twenty-six …

Both the number and breadth of avian cognition studies have expanded in the past three
decades. Parrots have a long history as subjects in avian cognition research. This paper …

Highlights•Turning bias in fish is considered relatively fixed and linked to escape
performance.•We exposed fish to a predictable threat at noon or in the evening.•Fish had …

The scale-eating cichlid Perissodus microlepis exhibits significant lateralised predation
behaviour using an asymmetric mouth. But how the acquisition of the behavioural laterality …
