examines the affect of expertise on aesthetic evaluations and emotional responses to auditory (music), visual (art), and audiovisual displays. Musicians, artists, and non-experts will be presented with emotion-eliciting visual and auditory stimuli, presented alone and together, and will report ratings of valence (whether the emotion is positive or negative), intensity of the emotion (weak or strong arousal), and several scales of aesthetics while an eye-tracker records physiological measures of ocular gaze (i.e., visual gaze path, fixation times, and pupil dilation). The use of eye-tracking equipment will add significant support to research on the effects of expertise on emotional and aesthetic responses to music and art, a research topic that has not relied on physiological measures in the past. The observations provided by subjective ratings in conjunction with physiological data will make important contributions to an improved understanding of the mechanisms involved in emotional reactions and the processes involved in the appreciation of music and art.
Neural Correlates of Human Trust in Automation
STUDENTS Catherine E Devlin ADVISORS Susan T Davis LOCATION, TIME RecPlex, 11:00 AM-12:30 PM Psychology, Poster - Honors Thesis My thesis was conducted Wright Patterson Air Force Base. This study focuses on the developmentof trust with a computer system and its neural correlates. This was accomplishedlooking at EEG data from participants as they perform a task that is automated, AF_MATB.
Put Your Money Where Your Mouth is: Feedback Reduces Overconfidence When Betting
STUDENTS Adam Barnas, Megan K Dailey, Kristen A Kemp, Peter M Sismour ADVISORS Susan T Davis LOCATION, TIME RecPlex, 11:00 AM-12:30 PM Psychology, Poster - Independent Research Previous research has shown that overconfidence, or the belief that one can perform better on a task than one actually can, is associated with risky behavior, or the willingness to place high bets on uncertain answers (Campbell, Goodie, & Foster, 2004). The present research evaluated the relationship between overconfidence, risky behavior, and narcissism, or excessive self-admiration that leads to an unrealistic view about one’s physical and mental capabilities. Participants were given a series of questionnaires and completed assessments of overconfidence, risky behavior and narcissism. They were then assigned either to place bets using virtual money to express their confidence in the accuracy of their answer (betting condition) to a series of general knowledge questions (GKQs), or to rate their confidence in their ability to accurately answer (confidence condition) the same series of GKQs. To examine the effect of timing on reported confidence, participants either rated their confidence before or after responding to each GKQ. To examine the effect of feedback on confidence, participants either received or did not receive feedback after answering each GKQ. Preliminary analyses reveal that participants in the betting condition were less overconfident than participants in the confidence condition, and that there was no significant relationship between narcissism and overconfidence. Additional analyses are expected to indicate that participants receiving feedback after answering the GKQ will show a reduction in confidence over the course of responding to the GKQs. Consistent with other published research (Mamassian, 2008), results are expected to indicate that confidence will be greater before responding to the GKQ, an effect of anticipatory overconfidence, or inability to estimate the magnitude of subjective uncertainty in decision making.
Visual Cues used for Relative Distance Judgements in 2D Displays
STUDENTS Laura A Janosko ADVISORS Susan T Davis, Benjamin R Kunz LOCATION, TIME RecPlex, 11:00 AM-12:30 PM Psychology, Poster - Honors Thesis Our experiment will investigate distance judgments in computer generated 2D displays. Distance judgments in 2D images are made all the time in fields such as architecture and design, the medical field and satellite images. Our experiment will investigate the role of the depth cues shadows and texture. A 2D display of a desktop with between 5 to 8 objects will be presented to participants. Each scene will have two conditions: high quality (simulations of objects with correct texture and shadow information) and low quality (objects have incorrect texture information and no shadows). Unit-less relative distance judgments will be made between objects to determine if the visual cues texture and shadow information aid in spatial perception. An eye tracker will be used to determine on which visual cues participants rely. Results will provide information about how shadow and texture information in 2D displays are used in spatial perception. Our hypothesis is that participants will be more accurate in high 69
