“…This result is consistent with the concept of social comparison theory, which assumes that individuals tend to put more effort to maintain positive self-image in a publicly-observed situation (Tafkov, 2013;Webster, Duvall, Gaines, & Smith, 2003); and goal setting theory, which posits that attainable goal will keep individual's effort at the level that is in line with the goal achievement (Locke, 1996). It is argued that the presence of RPI creates an incentive and motivation for individuals with high goal commitment to outperform others in a publicly-observed setting since the presence of RPI has been shown to motivate individuals to exert more effort (Kramer, Maas, & Rinsum, 2016;McFarland & Miller, 1994), and that a high level of goal commitment itself reflects the individual's unwillingness to neglect the current goal attainment process (Hollenbeck & Klein, 1987).…”
