Table 3.

Extreme ranges of performance of AS participants divided in terms of individual differences in FI^*.

	Average FI	Inferior FI	Superior FI	pa
	N = 10	N = 4	N = 5
Sub-normal performance				0.015
Median	2	4	0
Range	0–6	1–9	0–1
Supra-normal performance				0.099
Median	0	n.a	1
Range	0–2	n.a	0–4

^*Number of measures from the neuropsychological battery (except RPM) where performance was either 2SDs below (sub-normal performance) or above (supra-normal performance) from the control mean (see Section Multiple Case Series Analyses (MCSA) for description of process to divide FI groups).
