Self-control, attention, and impulsivity jointly support goal-directed behavior yet are often examined in isolation with heterogeneous measures. We integrate validated self-reported scales with a hybrid, incentivized behavioral task that synthesizes two canonical experimental designs and adds novel extensions to measure these constructs in a typical work context. Using data from a preregistered four-session online study (N = 443 adults), we characterize the cross-relationships and the relationships between different measures of self-control, attention, and impulsivity and evaluate their contributions to effort allocation over time. More broadly, the study advances an emerging research program that leverages laboratory settings with well-structured economic incentives to examine the role of personality traits and cognitive limitations in economic decision making.
