Post-task self-report questionnaire items and Pearson correlations with the computational model parameters^*

Question†	Mean ± SD	Pearson correlations
		Emotional conflict (EC)	Decision uncertainty (β)
1. I found the POSITIVE pictures enjoyable	5.05 ± 1.68	0.07	0.02
2. The NEGATIVE pictures made me feel anxious or uncomfortable	4.43 ± 1.99	0.32‡	0.06
3. I often found it difficult to decide which outcome I wanted	2.51 ± 1.73	0.10§	0.45‡
4. I always tried to move ALL THE WAY TOWARD the outcome with the LARGEST REWARD POINTS	4.76 ± 2.30	−0.74‡	−0.48‡
5. I always tried to move ALL THE WAY AWAY FROM the outcome with the NEGATIVE PICTURE/SOUNDS	2.98 ± 2.17	0.67‡	0.37‡
6. When a NEGATIVE picture and sound were displayed, I kept my eyes open and looked at the picture	5.5 ± 1.83	−0.37‡	−0.17‡
7. When a NEGATIVE picture and sound were displayed, I tried to think about something unrelated to the picture to distract myself	2.96 ± 1.94	0.29‡	0.11§
8. When a NEGATIVE picture and sound were displayed, I tried other strategies to manage emotions triggered by the pictures	3.26 ± 1.99	0.32‡	0.05
