Whether frontal functions sharing common neural substrates could affect the performance of each other is largely unknown. This study investigated the relatedness of performances in decision making and odor identification (OI) which are commonly subserved by the orbitofrontal cortex. Forty-four Chinese females aged 23 to 55 years were assessed by the Sniffin’ sticks for their OI and were divided into high OI group and low OI group by a mean split of their OI scores. The Risky-Gains Task (RGT; Paulus et al., 2003) was employed to assess for their risk-taking decision making. Our findings showed that participants with higher OI significantly took more risky choices compared to their counterparts with lower OI (p = .033). While showing no significant difference in risk-taking after claiming for safe choices (p > .05) or after receiving risky rewards (p > .05), the high OI group took more risky choices than the low OI group in trials preceded with punishment (p = .013). These findings suggest that frontal functions sharing similar neural substrates could relate with each other by positive coupling of their performances.
