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.

Using the Mori technique in which two different movies presented on the same screen were viewed separately by two groups without their noticing the duality, two experiments were carried out with 138 undergraduates in groups of varying sizes to examine the effects of cowitnesses with the same or different information on these witnesses' memory distortion. Exp. 1 investigated the cowitness effects in a one-versus-two situation, while Exp. 2 investigated the effects in a two-versus-two situation. Analysis showed isolated eyewitnesses who had no supporting cowitnesses changed their minds more frequently toward the majority and, when they had a cowitness who shared the same information, they tended to stick to their original reports even after being confronted with conflicting information in a discussion.
