Aggression, sex and individual differences in cerebral lateralization in a cichlid fish
Evidence is presented that the strength of lateralization is linked to a behavioural trait, aggressiveness, in the convict cichlid (Archocentrus nigrofasciatus), and that this relationship depends on the sex of the fish.
