Adjusted Means (Adjusted for Leiter-R Mental Age) and Between-Group Differences for the Types of Perseveration in Narration

Outcome	FXS-O (n = 26)	FXS-ASD (n = 23)	DS (n = 25)	TD (n = 25)
Utterance-level perseveration	0.11(.01)^a	0.14(.01)^a	0.11(.01)^a	0.21(.01)^b
Topic perseveration	0.03(.01)^a	0.04(.01)^a	0.03(.01)^a	0.04(.01)^a
Conversational device perseveration	0.00(.01)^a	0.00(.01)^a	0.00(.01)^a	0.01(.01)^a

Note. FXS-O = Fragile X syndrome only; FXS-ASD = Fragile X syndrome with autism spectrum disorder; DS = Down syndrome; TD = typically developing. Different superscripts within a row indicate significant differences. If groups share the same letter, differences were not significant.
