Ratings on item 55 (awareness of social distancing) in ASD and siblings.
A) Mean ratings for each group; error bars reflect standard error of the mean (SEM). B) histograms showing the number of individuals who received each rating on item 55. Scores range from 0 to 3, with higher scores reflecting a greater frequency of social distancing abnormalities.
Figure 2.
Correlations between ratings on item 55 (white) and all other SRS items.
The three items with the highest correlations were items 52 (“Knows when he or she is talking too loud or making too much noise”), 56 (“Walks in between two people who are talking”), and 63 (“Touches others in an unusual way (e.g., he or she may touch someone just to make contact and then walk away without saying anything)”), all of which relate to the concept of social distancing.

Ratings on item 55 (awareness of social distancing) in ASD and siblings across age bins (from 4 years to 18 years).
Error bars reflect standard error of the mean (SEM). Group differences were present at every age bin (all p<0.005, Mann-Whitney U test).

Relationship between personal space and interpersonal distance preferences in ASD and control adults.
The correlation between these two measures is stronger in the control group (Panel A; r = 0.881, p<0.000001) than in the ASD group (Panel B; r = 0.562, p = 0.0151). Residuals were derived from regression lines fit to each group separately. Absolute values of the residuals are plotted for control and ASD groups (Panel C). Groups were different on this measure (t(36) = 2.95, p = 0.0055), with the ASD group displaying greater residuals, indicating a less tight relationship between personal space and interpersonal distance preferences.
