Improving Stimulus Realism: The Effect Of Visual Dimension On Affective Responding, Shannon Compton
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 …

Development And Validation Of A Battery Of Emotionally Evocative Film Clips For Use With Young Children, Lindsay Gabel

Investigating normative and maladaptive emotional development requires the ability to elicit children’s reactivity to a range of affective stimuli. However, the field lacks a validated battery of stimuli tapping a broad range of childhood emotions. We therefore sought to validate a developmentally appropriate battery of emotionally evocative film stimuli, covering a range of affective responses, for use with children. During pilot work, clips were verified as age-appropriate by parents of young children. Next, during a laboratory visit, 39 children (22 girls; Mage = 7.19 years, SD = .76) viewed 20 film clips thought likely to elicit either positive affect, …
