Cognitive or emotional evaluation and RT for each word category per each judgment task in the fMRI experiment

	Self-relevance judgment		Other-relevance judgment		Main effect		Interaction
	Death-related words	Death-unrelated words	Death-related words	Death-unrelated words	Task	Word
Variable	M (S.D.)	M (S.D.)	M (S.D.)	M (S.D.)
Effect of word type

Notes: Means and S.D. of cognitive or emotional evaluation and RT are shown in the second to fifth column (left to right). Thoughts of death, arousal, and imageability were rated on a 7-point scale (1 = not at all, 7 = very much). Relevance was rated on a 4-point scale (1 = not relevant, 4 = relevant). Emotional valence was rated on a 7-point bipolar scale (−3 = very negative, +3 = very positive). Relevance ratings and the RTs were obtained during the fMRI scanning, and the remaining variables were obtained after scanning.

^* P < 0.05; ^**P < 0.01.

^aThe simple main effect of stimulus type was significant in the Self task.

^bThe simple main effect of stimulus type was significant in the Other task.

^cThe simple main effect of task type was significant in the “death-related words” condition.

^dThe simple main effect of task type was significant in the “death-unrelated words” condition.
