Percentage distribution of left-handed (L), right-handed (R) and ambipreferent (A) individuals in sugar gliders. The direction of manual lateralization in all types of behaviour studied was found to be significantly influenced by the animals’ sex, therefore distribution is given separately for two sexes (feeding (a,b) and tripedal stance (c): 12 males, 11 females; nest-material collecting (d): 9 males, 10 females). Distribution of subject’s preferences tended to be more symmetrical in males, than in females, among whom there were more left-handers.
