Fig. 4: Risk escalation is not due to motor learning.
From: Escalating risk-taking is linked to emotional habituation

Displayed on the Y axis is the number of participants who reached the plank’s edge on each trial repetition (on the X axis) in the main experiment (N = 159) and the control experiment (N = 30). All but one participant reached the plank edge on their very first attempt in the control experiment, while in the main experiment, only eight subjects did so. This suggests that the gradual escalation in risk-taking is not due to subjects becoming better at walking down a virtual plank.
