Happy facial emotion will receive more investment amount, while angry facial emotion will receive less investment amount. H3: When facial emotion and behavioural information are incongruent, participants are more inclined to rely on behavioural information to make trust choices. H4: The arousal of facial emotion influences participants’ trust choices. Players with high-arousal happy facial emotion will receive more investment than those with low-arousal happy facial emotion.
