A psychologist hypothesizes that people are more likely to follow through on a goal if they share it with someone whose opinion they value, rather than keeping it private or sharing it casually.
Which experimental finding, if true, would most strongly support the psychologist's hypothesis?
- A
Goals related to health were more common than goals related to study.
- Bcheck_circle
Participants who shared their study goal with a respected mentor completed significantly more practice than those who shared with a casual acquaintance or no one.
- C
Most participants reported having at least one important goal at the time of the study.
- D
Participants who shared goals reported feeling more confident, regardless of the listener.
Explanation
A directly tests the listener's identity (respected mentor) and behavior (follow-through), aligning with the hypothesis. B, C, and D do not isolate the variable specified.
