Consistent individual differences in behaviour across time or contexts (ie personality types)
have been found in many species and have implications for fitness. Likewise, individual …

The medaka, Oryzias latipes, is rapidly growing in importance as a model in behavioural
research. However, our knowledge of its behaviour is still incomplete. In this study, we …

There have been many investigations into consistent, individual differences in behavior
(animal personalities), but rather less attention has been given to the possibility that …

Previous studies have demonstrated that animals use both environmental cues and
egocentric information when orienting in mazes or nature. These two strategies have been …

Compared to rodents, the relationship between anxiety and cognitive performances has
been less studied in birds. Yet, birds are frequently exposed to stimulations that constitute a …

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 …

Theoreticians predict that animal 'personality'traits may be maladaptive if fixed throughout
different contexts, so the present study aimed to test whether these traits are fixed or plastic …

Highlights•We examined personality, stress physiology and learning performance in Florida
scrub-jays.•Associative and reversal learning performance were inversely related.•Nestling …

In most experimental work on animal cognition, researchers attempt to control for multiple
interacting variables by training subjects prior to testing, allowing subjects to participate …

Individual differences in animal behaviour have been attracting the interest of researchers at
least from the time of Darwin (Slater 1981; Caro & Bateson 1986; Clark & Ehlinger 1987; …
