Figure Legend: From: An escape from crowding Journal of Vision. 2007;7(2):22. doi:10.1167/7.2.22 Figure Legend: Reducing the spacing. (a) Capacity (the estimated number of letters monitored by the observer) during change detection for letters with wide (3.7°) spacing (gray) and narrow (1.1°) spacing (blue), with and without a cue. Average results for two observers (J. F. and S. B.); error bars show standard error between observers. (b) Capacity during change detection for letters with wide (3.7°) spacing (gray) and extra-narrow (0.63°) spacing (yellow), with and without a cue. Results for observer J. F.; error bars show standard error within observer. (c) Sensitivity d′ during change detection for letters with wide spacing and narrow spacing, with and without a cue. Average results for two observers (J. F. and S. B.); error bars show standard error between observers. d′ = z( h) − z( f), where h is the hit rate, f is the false alarm rate, and z is the inverse cumulative normal distribution function. (d) Hit rate (wide bars) and false alarm rate (narrow bars) during change detection for letters with wide and narrow spacing. Average results for two observers (J. F. and S. B.); error bars show standard error between observers. * p < 0.05. ** p < 0.01. Date of download: 11/7/2017 The Association for Research in Vision and Ophthalmology Copyright © 2017.
