Predicted effects of valence and arousal on the up- and down-regulation of emotion across picture categories

		Picture category
	Measure	Pleasant	Unpleasant
Arousal-dependent modulation	SCRs	Increase > Decrease	Increase > Decrease

	Startle magnitude	Increase > Decrease	Increase > Decrease

	Heart rate deceleration	Increase < Decrease	Increase < Decrease

Valence-dependent modulation	SCRs	Increase = Decrease	Increase = Decrease

	Startle magnitude	Increase < Decrease	Increase > Decrease

	Heart rate deceleration	Increase < Decrease	Increase > Decrease

Note. SCRs = skin conductance responses.
