Direction of limb preferences in sugar gliders. Direction is given separately for in male and female groups (feeding and tripedal stance: 12 males, 11 females; nest-material collecting: 9 males, 10 females). Mean HI scores ± SE for four types of unimanual behaviour (positive values indicate left lateral bias, negative values indicate right lateral bias). *P < 0.05; n.s.: non-significant. In all behaviours females showed group-level preference for use of the left forelimb, while males had no across group consistent preference.
