patterns. The commonly categorized patterns were then averaged to identify which noise pixels
influenced expression categorization. In addition, sad or happy music was played during the face
judgment task to manipulate the mood of observers. Based on previous research, we
hypothesized that different noise pixels would be important in expression categorization
depending on the manipulation mood. The results find that noise pixels around the corners of the
mouth are important in determining the categorized facial expression, but that there was no
difference in the cues used to make judgments between mood groups. The mood manipulation
was not statistically significant; however, the analysis of facial expression interacted with mood
context. These findings line up with that of Kontsevich and Tyler (2004) and provide evidence
for an objective analysis of facial expression.
Emotion Yields Isolated Tunnel Memory, But Collaborative IMAX

Recollection is frequently social; people tend to remember with others and when they do, their
joint recollection is enhanced (McClure et al. 2009). Group recall tends to be superior to isolated
recall. However, subjects viewing emotional material tend to focus in on the central, emotional
aspects of the scene (Safer & Christianson, 1998). Thus, if groups experience an emotional
scene, their recollections should be similar. 114 Butler University students viewed one of two
slideshows including 15 photos taken in various places at a house. One group saw a slideshow
that contained a non-emotional version of the middle scene (cutting bread) and three extra nonemotional
scenes (food). The other group saw an emotional version of the middle scene (cut off
fingers) and three extra emotional scenes (ER photos). Three critical slides showed multiple
household items varying in placement, central or peripheral. After the three-minute presentation,
and a 10-minute interpolated task, subjects completed a memory questionnaire. Participants
completed the questionnaires either by themselves or with partners and were asked to work
together. In free recall, arousal allowed the isolates to improve their recall of central items with
no effect on the groups’ superior recall, whereas arousal improved the accuracy of the groups’
peripheral recall with no effect on isolates’ poor recall. For the probed recall, arousal improved
the group memory for peripheral items, but there was no difference for the central data. This
further backs up the memory model that under emotional conditions, peripheral group memory is
improved.
Implicit Association Test vs. Police Officer’s Dilemma, Which is Better for Increased
Prejudicial Awareness?

In the quest for reducing prejudicial thinking and biases the question has become how can that be
done best? A possible avenue lies within the applications of two tests designed to activate the
processes necessary to learn from their outputs. The Implicit Association Test (IAT) examines
participants’ unconscious race-related biases, through dual-categorization task that allows
participants to assign stimuli to racial and evaluative categories. The Police Officer’s Dilemma
(POD) task submerses participants in a quick reaction video-game like setting. Participants have
to respond shoot vs. don’t shoot to White vs. Black men holding guns vs. benign objects (Correll,
Judd, Park, &Wittenbrink, 2002). 200 introductory psychology students will be randomly
