Final answer:
Research indicating that commitment and financial incentives impact goal achievement is true, but contingent on how these incentives are perceived and their potential effects on intrinsic motivation.
Step-by-step explanation:
The statement that research suggests that the level of commitment and financial incentives affect whether goals are achieved is true. Various studies have indicated that an individual's commitment to a goal and the prospects of financial rewards can significantly influence the likelihood of achieving those goals. However, it's important to note the nuances in how these factors interact.
For instance, according to Deci et al. (1999), if financial incentives or other tangible rewards are expected, they may reduce intrinsic motivation. Conversely, if such rewards are unexpected, intrinsic motivation may be sustained. This complements social exchange theory, which suggests that in relationships, individuals seek to maximize benefits and minimize costs.
