Examination of the passive facial feedback hypothesis using an implicit measure: with a furrowed brow, neutral objects with pleasant primes look less appealing.

98 undergraduates (54 men, 44 women) participated in an experiment to examine whether having an artificially furrowed brow would have an effect on participants' subjective impression of perceived targets. An elastic adhesive bandage was either stretched to create furrows on the brow when it retracted, or not stretched so as to avoid creating wrinkles. While wearing the bandages, the participants rated their impressions of neutral targets preceded by agreeable, disagreeable, or neutral primes in a modified Affect Misattribution Procedure. The results showed that participants with artificially furrowed brows tended to rate the neutral targets preceded by agreeable primes less favorably than did the control participants, while both groups rated similarly the targets preceded by disagreeable primes.
