Figure 2. (Left) Risk decision-making task. Participants chose between a "safe" and "risky" option. While making choices, they were observed via camera by an on-screen face—either a real human or an avatar. If they selected the risky option, the outcome (win or no win) was followed by the observer displaying a facial expression: admiration for wins, contempt for losses. The avatar and human face conditions alternated every 6 to 13 trials. When the safe option was selected, the participant received the reward and moved on to the next trial. Reward values and probabilities changed each trial, with one option always being 100%.(Right) Increase in risk-taking under the avatar condition. The red line shows the average risk-taking rate under the Avatar condition, and the blue line under the Human condition. The x-axis represents the expected value difference between the two options. When the risky option was only slightly better (moderate expected value differences), participants were more likely to choose it under the Avatar condition.
