		Attribution Category
	Importance	Internal	External	Normative

White Bear (n = 98)	1.34^a (.57)	1.24^a (.34)	2.42^b (.85)	3.41^c (.88)
Career (n = 87)	3.26^a (1.09)	1.46^b (.65)	2.34^c (.87)	3.28^a (.89)
Accident (n = 95)	3.01^a (1.17)	1.43^b (.59)	2.23^c (.83)	3.24^a (.90)
List (n = 96)	2.79^a (1.11)	1.59^b (.74)	2.44^c (.80)	3.44^d (.86)

Note: Attribution category differences are noted by unique letter superscripts (i.e., ‘a’ versus ‘b’) and are all significant at p < .01. The sample sizes reflect the number of participants (out of 126) that reported failure suppressing that particular thought.
