The experiment was programmed using PsychoPy and data were collected in the laboratory.Study 3 involved 96 participants who did not major in psychology or economics via the online platform Cognitive Experiment Standard Toolbox (CEST). 4 participants were excluded due to failing to complete the task, leaving 92 participants for data analysis (self-reported gender: 58 females, 22.63 ± 2.93 years).The experimental data includes:(1) participants' investment in each trial (inv_s)(2) partners' investment in each trial (inv_o)(3) participants' earning (return_s)(4) partners' earning (return_o)
