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
Development And Validation Of A Battery Of Emotionally Evocative Film Clips For Use With Young Children, Lindsay Gabel
Electronic Thesis and Dissertation Repository
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, …
The Effects Of Perceptual Fluency On Emotional Word Recognition, Joseph M. Nidel
The Effects Of Perceptual Fluency On Emotional Word Recognition, Joseph M. Nidel
Electronic Thesis and Dissertation Repository
To investigate if making a word harder to read attenuates emotional influences like valence and arousal, we used a sample of Warriner and colleagues’ (2013) corpus with valence and arousal norms, a font manipulation from the perceptual fluency paradigm, and a word naming task. We found that, contrary to our hypotheses, emotional influences of words on RT were not attenuated in the disfluent condition; in fact, disfluency seemed to amplify the facilitative effects of high arousal. These results suggest that models of word recognition should consider the role that emotions play in recognition. They also provide limited support to models …
Investigating The Interaction Of Emotion And Cognition: Conflict Adaptation And The Impact Of Emotionally-Salient Distraction, Samantha Goldsmith
Investigating The Interaction Of Emotion And Cognition: Conflict Adaptation And The Impact Of Emotionally-Salient Distraction, Samantha Goldsmith
Electronic Thesis and Dissertation Repository
Individual differences in cognitive control have significant implications for a broad range of everyday functions, from driving a car to maintaining healthy relationships. In a world filled with salient, task-irrelevant information, it is imperative to investigate cognitive control in the context of distraction. The current study investigated the interference effect of emotional versus non-emotional distraction in a conflict adaptation paradigm. Forty-seven young adults completed several individual difference measures and an emotional flanker task. Results failed to support the hypothesis that distractor valence would interact with prior and current flanker congruency, but showed a trend toward an effect of distractor valence …
Popular Music-Evoked Autobiographical Memories - Developing A Database Of Songs And Studying The Role Of Cue Emotionality And Relevance On Recalled Memories, Krysten Zator
Electronic Thesis and Dissertation Repository
In Study 1, undergraduate students rated popular music songs on several factors. A database of knowledge was created for popular music autobiographical memory (AM) cueing research. Study 2 examined the role of emotional experience and relevance associated with a popular music AM cue on recalled AMs. In Phase 1, undergraduate participants described AMs to short music clips or a blank computer screen (control). In Phase 2, participants answered questions about these AMs. In Phase 3, participants rated musical clips (including Phase 1 stimuli). Unexpectedly, music-cued memories were less salient and did not differ emotionally from control-cued, but contained more perceptual …
The Process Dissociation Of Moral Judgments: Clarifying The Psychology Of Deontology And Utilitarianism, Paul Conway
The Process Dissociation Of Moral Judgments: Clarifying The Psychology Of Deontology And Utilitarianism, Paul Conway
Electronic Thesis and Dissertation Repository
A growing body of work has examined responses to moral dilemmas where causing some degree of harm leads to a greater positive outcome; such dilemmas are said to pit deontological philosophical considerations (causing harm is never acceptable) against utilitarian philosophical considerations (causing harm is acceptable if it leads to the best possible outcome). According to dual-process theories of moral judgment, independent processes drive each judgment: affective reactions to harm drive deontological judgments, whereas cognitive evaluations of outcomes drive utilitarian judgments. Yet, theoretically both processes contribute to each judgment; therefore, it is an error to equate judgments with processes. To overcome …
Shared Neural Substrates Of Emotionally Enhanced Perceptual And Mnemonic Vividness, Rebecca M. Todd, Taylor W. Schmitz, Josh Susskind, Adam K. Anderson

It is well known that emotionally salient events are remembered more vividly than mundane ones. Our recent research has demonstrated that such memory vividness is due in part to the subjective experience of emotional events as more perceptually vivid, an effect we call emotion-enhanced vividness, or EEV. The present study built on previously reported research in which fMRI data were collected while participants rated relative levels of visual noise overlaid on emotionally salient and neutral images. Ratings of greater EEV were associated with greater activation in the amygdala, visual cortex, and posterior insula. In the present study, we measured BOLD …
Inclusive Fitness, Reciprocal Altruism And Emotion: Testing A Social-Functional Model Of Anger And Gratitude Across Kin And Non-Kin Relationships, Harris Rubin
Electronic Thesis and Dissertation Repository
Guided by the theories of inclusive fitness (Hamilton, 1964) and reciprocal altruism (Trivers, 1971), two studies tested hypotheses related to the notion that emotions are part of an evolved psychological system that functions, in part, to regulate social exchange. Emotional experience and exchange behaviors were predicted to vary based on both the structure of the situation and the type of relationship one has with a partner. Due to an absence of inclusive fitness effects, interaction with non-kin (compared with kin) exchange partners was expected to trigger more intense emotional responses. Study 1 found that, as expected, unfair offers led to …
