Table 1.

Predictions of conservation. Notes: Based on the demos, the table predicts the experimental outcomes, noting whether the flanker features are symmetrical or not and which critical spacing is conserved across manipulations. Symmetry is assessed along the axis of crowding.

Experiment	Flanker	Symmetrical distribution of features?	Conserved critical spacing
1: Length	Lopsided	No	Edge
2: Size	Lopsided	No	Edge
2: Size	Letter	Yes	Center
3: Orientation	Rotated lopsided	Yes	Center
