Influence of body tilt on perceived object stability.

<p>(<b>A</b>) Stimuli. Critical angle (CA) predictions (shaded areas) relative to physical (red) and perceived (blue) gravity. (<b>B</b>) Results. Mean CA when upright (▾), left (•) and right side down (▪) for objects with a different COM relative to physical (black) and perceived (coloured solid lines) gravity. Linear regression slopes are shown as coloured dashed lines. Error bars are ±1 S.E. Cartoon inserts indicate the extent to which the SVV shifts towards the body. (<b>C</b>) Correlation (dashed line) between the SVV and the perceived CA averaged across all objects. Here the perceived gravity prediction is based on the average SVV setting and the physical gravity prediction is based on the ground truth CA averaged across the five objects. (<b>D</b>) Correlations between the CA and the SVV for each participant ordered according to the CA-SVV slope. Underlined initials identify control experiment participants.
