The Role Of Racial Information In Infant Face Processing, Angela Nicole Hayden

University of Kentucky Doctoral Dissertations

The present research addressed the development of specialization in face processing in infancy by examining the roles of race and emotion. An other-race face among own-race faces draws adults’ attention to a greater degree than an own-race face among other-race faces due to the “other-race” feature in other-race faces. This feature underlies race-based differences in adults’ face processing. The current studies investigated the development of this mechanism as well as the influence that this mechanism has on emotion processing in infancy.

In Experiment 1, Caucasian 3.5- and 9- month-olds exhibited a preference for a pattern containing an Asian face among …

The Contribution Of Nmda Receptors Within The Central Nucleus Of The Amygdala To The Suppression Of Pain Affect, Catherine Ann Spuz

Wayne State University Dissertations

The amygdala processes stimuli that threaten an individual and organizes the execution of affective behaviors designed to cope with the threat. The prototypical threat to an individual is exposure to a noxious stimulus. The central nucleus of the amygdala (CeA) receives nociceptive afferents and exhibits neuronal activation in response to noxious peripheral stimulation. NMDA receptors within CeA mediate this noxious-evoked neural excitation, and previous studies in the laboratory have shown that blockade of CeA NMDA receptors via the antagonist APV elevates the threshold for noxious tail-shock-induced vocalization afterdischarges (VADs), a validated measure of pain affect in the rat. The present …

The Influence Of Individual Differences In Emotional Clarity On Sensitivity To Situational Cues, Elizabeth Lauren Foreman

Electronic Theses and Dissertations

The influence of individual differences in emotional clarity on the use of situational cues in decision making was investigated. Accuracy of situational cues was manipulated in the form of ostensible previous ratings given to participants while viewing pleasant, neutral, or unpleasant pictures. Of importance to this study was whether persons low in emotional clarity would rely more on situational cues, regardless of their accuracy, than would persons high in this trait. Personality was assessed using two scales which measure emotional clarity. Self-monitoring was also examined as a possible moderator of any findings. Contrary to predictions, our findings indicated that individuals …

Emotion Recognition In Schizotypy, Laura Brown

LSU Master's Theses

Deficits in social cognition are repeatedly found in individuals with schizophrenia. Facial emotion recognition is a major aspect of social cognition in which individuals with schizophrenia show consistent deficits. However, many questions about these deficits remain unanswered including whether they occur in individuals with schizotypy—those at high risk for the disorder that do not manifest full pathology. Examining emotion recognition in schizotypy eliminates many of the confounds associated with schizophrenia research such as medication effects, chronic institutionalization, and generalized cognitive deficits, and allows for the examination of whether emotion recognition deficits reflect vulnerability to schizophrenia. Prior research in this population …

The Influence Of Emotion On Attention : Examining The Processing Of Negative And Positive Emotion Words In The Dot Probe Task, Tina Sutton

Legacy Theses & Dissertations (2009 - 2024)

The influence of emotion on attention has been examined more closely in recent years using a variety of paradigms. Öhman (1993) suggested that participants more readily pay attention to negative information than neutral information. The current work was designed to expand upon these findings by examining both negative and positive emotion word processing in a non-clinical population using the dot probe task. Experiments 1a and 1b examined the supraliminal and subliminal processing of negative and positive emotion words presented in separate blocks. The results revealed that participants responded faster to the probe when it appeared in the same location as …
