Hemispheric Interactions and Event-Related Potentials in Lateralized Stroop and Stroop Analog Tasks

Description: Classical Stroop stimuli and newly developed face/word Stroop analog stimuli were used to investigate hemispheric interactions in Stroop interference effects (SEs) and corresponding event-related potentials (ERPs). Lateralized stimuli were presented unilaterally and bilaterally as congruent or incongruent color strip-word or face-word pairs (to invoke right hemisphere (RH) and left hemisphere (LH) specialization, respectively, in the latter case). The common finding for such tasks is that responses for the congruent condition are faster and more accurate than for the incongruent condition (i.e., the SE). A primary prediction is that the SE will be maximized when both the distractor and target components, or distractor alone, are presented to the specialized hemisphere (i.e., LH for words and RH for faces). A total of 88 right-handed University of North Texas students participated in one of four experiments. Participants manually responded to one component of the stimuli (i.e., color, face, or word), while ignoring the other. Behaviorally, participants showed a robust SE across all experiments, especially for the face/word task with word targets. Findings from the face/word Stroop analog tasks also indicated that SEs were produced by selective attention to either faces or words, implicating a role for top-down (controlled) processes. Hemispheric asymmetries were observed only for bilateral presentations of the face/word Stroop analog stimuli and did not differ for word versus face targets. The results suggest that the LH is less susceptible to interference from the RH than vice versa. Electrophysiologically, anterior N1 and P1, posterior P1 and N1, N2, and P3 components were identified. A SE was found for P3 amplitudes, but not latencies, across all four experiments such that the congruent condition generated greater amplitudes than the incongruent condition, suggesting that the P3 is an index of task difficulty. Surprisingly, SEs were also observed for the early ERP components, albeit embedded in ...

The Relationship between Incongruency, Dogmatism, and Social Desirability in College Students

Description: The purpose of this study was to determine if there was a relationship between the concepts of incongruency, dogmatism, and social desirability. It was assumed that high scores of social desirability would be related to low incongruity scores while high dogmatism scores would be related to high incongruity scores. The relationship between social desirability scores and dogmatism scores was also investigated.

Beliefs of Internal Versus External Control and Their Relationship to Stage of Moral Judgment

Description: This investigation sought to explore the relationship of Julian Rotter's concept of internal versus external control (I-E) to stages of moral judgment. The I-E dimension is defined as the attribution by the individual of responsibility for behavioral outcomes to either oneself or to outside entities. The internal oriented person believes that the events in which he is involved lie within his control. Conversely, the external oriented person believes that the events that happen to him are controlled by other factors.

The Relationship between Several Personality Variables and a Proposed Trait Model

Description: This thesis proposes three hypotheses: first, that persons with a high generalized expectancy for internal control of reinforcement will react to many of life's situations in a problem-solving or need-persistent way; second, that those persons high in the belief of external control will be more extra-punitive in their reactions to frustrating situations; third, that persons with a high belief in internal control of reinforcement are more ready to learn in chance situations.

The Draw-A-Person Technique as a Measure of Sexual Conflict

Description: Since much of the existing research which points to the low validity of the Draw-a-Person technique has used differentiation of diagnostic categories as a criterion, this study will be restricted to a consideration of the Draw-a-Person technique as a means for discriminating between a group of individuals who manifest conflicts in the area of sexual adjustment and a control group which does not show these conflicts in any appreciable amount.

MMPI-2 Patterns of Adults with Attention-Deficit Hyperactivity Disorder

Description: Recent literature suggests that not only does Attention-deficit Hyperactivity Disorder (ADHD/ADD) persist into adulthood, but it can also be accompanied by personality characteristics which cause emotional difficulties. In fact, adults diagnosed with ADHD can present with a profusion of difficulties. Several constructs appear to accumulate dynamically throughout development to place the adult with ADHD at risk for multiple emotional problems. These interwoven influences include familial characteristics, childhood emotional and academic difficulties, and inadequate coping skills to respond to adulthood pressures. This document, first, describes a developmental model for conceptualizing negative trajectories leading to nonadaptive coping and psychopathology and identifies personality factors of adults diagnosed with ADHD. This model provides clinicians and researchers with a better understanding of the complexity and challenges of adulthood ADHD in order to aid in diagnosis, treatment, and prevention. The purpose of this study is to examine personality factors common to adults diagnosed with ADHD and compares these characteristics with a group of adults diagnosed with a depressive disorder. Adults responding to a community advertisement who provided documentation of the diagnosis of Attention-deficit Hyperactivity Disorder were administered the MMPI-2. This ADHD group was compared with MMPI-2 profiles of a group of adults diagnosed with Major Depressive Disorder or Dysthymic Disorder. A cluster analysis procedure was performed and results are discussed.

Executive Control of Craving: An Examination of College Students

Description: Previous research has shown that alcohol abuse may cause a deficit in frontal lobe functioning, specifically, areas of the frontal lobe that are related to executive function. Additionally, problems with executive function have been related to increased difficulty in managing cravings to addictive substances. The current study explored the relationship between alcohol use and performance on measures of executive functioning in a sample of 121 traditional college students. Students were given 5 measures of executive function designed to explore mental set shifting, updating, inhibition, sustained attention, and planning. These measures were used to examine the relationship between executive function and craving as measured by the Obsessive Compulsive Drinking Scale. Levels of alcohol use were also examined using the Alcohol Use Disorders Identification Test in relation to executive function performance and family history of alcohol abuse.
