Simple slopes for Visual Analogue Ratings and IBI reactivity during conditioning task

Outcome	Reinforcer type	β (SE)
Visual Analogue Ratings	Neutral	5.38 (3.42)
	Points	5.46 (3.42)
	Positive image	1.69 (3.42)
	Aversive noise	−10.38 (3.42)
	Negative image	5.51 (3.42)
IBI reactivity	Neutral	−15.40 (4.78)
	Points	−16.30 (4.66)
	Positive image	−19.10 (4.61)
	Aversive noise	15.60 (4.78)
	Negative image	−28.00 (4.66)

For Visual Analogue Ratings slope represents post‐rating–pre‐rating. For inter‐beat intervals (IBIs) slope represents anticipation–stimulus.
