What was the independent variable in Casey et al (2011)?

Participants' cognitive control
High delayer or low delayer status
Reaction time on tasks
Emotional responses to stimuli

The correct answer is: High delayer or low delayer status

In Casey et al. (2011), the independent variable was the participants' status as either high delayers or low delayers. This classification was crucial to the study as it aimed to investigate the differences in cognitive control between individuals who had demonstrated varying levels of self-control during a delay of gratification task as children. By categorizing participants into these two groups, the researchers were able to examine how each group differed in terms of brain activity and behavioral responses during tasks that required self-regulation and impulse control. This focus on delayer status allowed for insights into how long-term self-control behaviors might be influenced by early experiences and can reflect broader cognitive processes, thereby establishing a clear link between childhood behavior and later cognitive functioning.
