Improving Stimulus Realism: The Effect Of Visual Dimension On Affective Responding, Shannon Compton
Electronic Thesis and Dissertation Repository
For decades researchers have used 2D stimuli under the assumption that they accurately represent real objects. This assumption has been challenged by recent vision and neuroeconomics research which has found that 2D images can evoke different neural and behavioural responses than real objects. The current study continues this line of research in the field of affective cognitive neuroscience; a field where small effect sizes are common and rapid habituation to affective stimuli used in the lab often occurs. The present study uses realistic 2D and 3D emotional images to determine the impact of visual dimension on affective responding. Subjective ratings …

When Faces "Feel" Familiar: The Role Of Affective Signals In Face Recognition, Lauren E. Dunphy

Previous research has suggested that there may be an increase in positive affect and autonomic arousal in response to seeing a familiar face. These studies rarely distinguish between faces for which there is only a “feeling” of familiarity, and faces for which this feeling is accompanied by the retrieval of semantic knowledge about the individual. In the current study we aimed to make that distinction. Participants made recognition judgments on famous and non-famous faces while galvanic skin responses (GSR), zygomatic muscle activity, and heart rate (HR) were recorded. We found increases in GSR (autonomic arousal), and zygomatic muscle activity (positive …
