TABLE 1.

Means and standard deviations (SD) for percent syllables stuttered (%SS) and syllables produced per minute (Syl/min) for persons who stutter (PWS) and normally fluent controls (CONT) during PET scanning. Each participant completed six scanning tasks: two monologues, two oral readings and two eyes-closed-rest conditions.

	Mean %SS			Mean Syl/min
	Monologue	Oral reading		Monologue	Oral reading
PWS (n = 18) (SD)	9.75 (10.39)	8.84 (10.05)	p = NS	177.4 (47.6)	175.2 (42.9)	p = NS
CONT (n = 12) (SD)	NA	NA		189.4 (31.3)	223.5 (20.8)	p = .003
				p = NS	p = .0002
