Read the notes: • Some studies found posture affects cognition • Other studies (e.g. O'Brien & Ahmed 2014) found no effect • The original studies had small sample sizes • Replication efforts produced mixed results Which sentence best CAPTURES the overall state of evidence?
APosture has no effect on cognition.
BPosture clearly affects cognition.
CPosture is unimportant.
DEvidence on posture's effect on cognition is mixed — early studies suggested an effect, but replications including O'Brien and Ahmed (2014) found no effect, and small sample sizes complicate the picture.
Answer & Solution
Correct answer: D. Evidence on posture's effect on cognition is mixed — early studies suggested an effect, but replications including O'Brien and Ahmed (2014) found no effect, and small sample sizes complicate the picture.
The notes describe a complex, mixed picture — not a clear yes or no. Option C captures this nuance: 'early studies suggested... but replications... and methodological concerns...' This is the kind of careful synthesis SAT R&W tests. A and B oversimplify in opposite directions; D doesn't address cognition.
