Affective Consequences Of Sleep Deprivation, Jared D. Minkel Aug 2010

Affective Consequences Of Sleep Deprivation, Jared D. Minkel

Publicly Accessible Penn Dissertations

Surprisingly little is known about the effects of sleep deprivation on affective processes. Although clinical evidence and introspection suggest that emotional function is sensitive to sleep loss, there are only three published studies that have experimentally manipulated both stress and emotion in a single experiment, the earliest of which was published in 2007. This dissertation presents findings from three studies that were designed to improve our understanding of the influence of sleep loss on affective functioning in healthy adults. Study 1 (Sleep and Mood) measured the effects of sleep loss on affect in the absence of specific probes. Three facets ...


The Hierarchical Structure Of Emotional Expressivity: Scale Development And Nomological Implications, John Jeffrey Humrichouse May 2010

The Hierarchical Structure Of Emotional Expressivity: Scale Development And Nomological Implications, John Jeffrey Humrichouse

Theses and Dissertations

Integrating existing models of emotional expressivity, the 3-level hierarchical model contains a general factor of emotional expressivity vs. inexpressivity at the highest level; relatively independent factors of positive and negative expressivity at the second-order level; and discrete expressivity factors of sadness, hostility, guilt/shame, fear, joviality, confidence and amusement at the lowest level. The bottom-up analytic strategy consisted of identifying first the structure of the discrete affects; subsequent second-order factor analyses supported the existence of the higher order factors. The Iowa Scales of Emotional Expressivity (ISEE)--a hierarchical set of scales--systematically incorporate the level of abstraction of the items to ...


From Mindless To Mindful Decision Making: Reflecting On Prescriptive Processes, Michaela Huber Jan 2010

From Mindless To Mindful Decision Making: Reflecting On Prescriptive Processes, Michaela Huber

Psychology and Neuroscience Graduate Theses & Dissertations

People frequently make judgments and decisions in ways that, in hindsight, they might prefer to have made differently. Their judgments and decisions may be strongly influenced by some attributes that people would prefer receive less weight (e.g. transient emotions, peripheral cues, and social influence), and people may neglect other attributes that they would prefer receive more weight (e.g. factual information, subjective experiences, and personal preference). The central claim in this dissertation is that asking people to reflect on prescriptive decision processes--how decisions should be made--elicits a psychological state of mindfulness where people are increasingly aware of and better ...


The Role Of Racial Information In Infant Face Processing, Angela Nicole Hayden Jan 2010

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 ...


Emotion Recognition In Schizotypy, Laura Brown Jan 2010

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 ...


The Influence Of Individual Differences In Emotional Clarity On Sensitivity To Situational Cues, Elizabeth Lauren Foreman Jan 2010

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 ...


The Contribution Of Nmda Receptors Within The Central Nucleus Of The Amygdala To The Suppression Of Pain Affect, Catherine Ann Spuz Jan 2010

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 ...
