摘要：Recent studies in behavioral economics and neuroeconomics have revealed that emotion affects impulsivity in intertemporal choice. We examined the roles of socio-emotional status (i.e., perceived stress, depression, quality of sleep, loneliness) in temporal discounting behavior by Japanese non-smokers in a generation-specific manner (20 - 70 s) with a relatively large sample size (N = 3450). We observed that 1) both men and women are the most impulsive in their 60 s; 2) education has a negative impact on impulsivity in men aged 40 - 49 and women aged 50 - 59; 3) perceived stress has a negative impact on impulsivity in men aged 60 - 69; and 4) sleeplessness has negative and positive impacts on impulsivity in men aged 40 - 49 and women aged 30 - 39, respectively. Biological and social factors underlying observed findings are discussed.
