Akin to handedness in humans, some animals show a preference for moving to the left or
right. This is often attributed to lateralised cognitive functions and eye dominance, which, in …

We studied detour responses of male mosquitofish faced with a vertical-bar barrier through
which a group of females was visible. Mosquitofish showed a consistent population bias to …

Behavioural lateralization, the asymmetric expression of cognitive functions, is reported to
enhance key fitness-relevant traits such as group coordination, multitasking and predator …

Despite the potential benefits gained from behavioural lateralisation, defined as the
asymmetrical expression of cognitive functioning, this trait demonstrates widespread …

Behavioural lateralization has been observed in many species of fishes during stimulus-
specific tasks. However, one area that has been overlooked is the study of naïve side bias in …

We studied detour responses of two species of poeciliid fish (Gambusia hoolbroki and
Girardinus falcatus) faced with a vertical-bar barrier, through which conspecifics of the same …

Preferential use of one side of the body for cognitive or behavioural tasks (lateralization) is
common in many animals, including humans. However, few studies have demonstrated …

Lateralized behaviour occurs in diverse animals, but relatively few studies examine the
phenomenon in invertebrates. Here we report a population-level left turn bias in the giant …

Studies over the past 30 years suggest that functional lateralisation occurs in many animal
species. Preferential eye use is ubiquitous among fish, and recently some advantages of …

Detour tests provide a reliable indicator of the presence of visual lateralisation. Previous
studies on fishes and birds suggest that preferences in choosing to detour an obstacle to …
