<p>The current study involved two experiments that examined the relationships between lack of control, need for structure, and self-stereotyping in older adults. Specifically, Study 1 tested whether personal control can affect the need for structure and aging self-stereotyping. The low level of control manipulated by the recall paradigm led to an increase in the need for structure and negative self-stereotyping. Additionally, the need for structure mediated the effect of lack of control on negative self-stereotyping. Accordingly, we designed Study 2 to assess whether the effect of lack of control on negative self-stereotyping would disappear if older adults were given the opportunity to satisfy their increased need for structure in another way. Specifically, Study 2 included a structure affirmation task after the perceived control manipulation. The results not only were the same as those of Study 1 but also revealed that providing an alternative structure affirmation task could mitigate the negative effects of lack of control.</p>
