Economic Decisions with Ambiguous Outcome Magnitudes Vary with Low and High Stakes but Not Trait Anxiety or Depression

Most of life’s decisions involve risk and uncertainty regarding whether reward or loss will follow. Decision makers often face not only about the likelihood outcomes (what are chances that I get a raise if ask my supervisor? What supervisor be upset with me for asking?) but also magnitude (if do raise, how large it be? If gets upset, bad consequences me?). Only few studies have investigated economic decision making ambiguous likelihoods, even fewer outcome magnitudes. In present report, we effects magnitude, risk, gains/losses in an decision-making task low stakes (Study 1; $3.60–$5.70; N = 367) high 2; $6–$48; 210) using within-subjects design. We conducted computational modeling to determine individuals’ preferences/aversions magnitudes, gains/losses. additionally association between trait anxiety depression parameters. Our results show increasing increased gain aversion unambiguous sure preference; participants became more averse gains relative risky gains. There were no significant on making. suggest as increase, people tend avoid domain (especially gains) prefer vs losses.
