Academic Achievement: Effects of Congruency, Consistency, Differentiation, and Modal Personality Types

Description: This investigation explored relationships between four determinants of first-semester undergraduate academic achievement derived from Holland's (1973) theory of vocational development. Groups of 438 male and 468 female students completed the Strong-Campbell Interest Inventory and were categorized in terms of congruency, consistency, differentiation, and modal personality type. Undergraduates with congruent college-major choices enjoyed greater academic success than students with incongruent cho… more

Effect of Anterior or Ventromedial Hypothalamic Stimulation on Immunoglobulin G

Description: Although research has linked central nervous system activity with changes in immunoresponsivity, research on the possible role of the central nervous system in altering a specific class of antibody is lacking. This study was an investigation of the possible relationship between anterior or medial hypothalamic functions on Immunoglobulin G. concentrations in rat serum. Thirty-six male albino rats were randomly assigned to three groups of equal size. Animals within the anterior hypothalamic grou… more

Effect of Nucleus Circularis and Lateral Preoptic Lesions on Osmotically Induced Drinking

Description: The area most widely associated with osmoreception has been the lateral preoptic nucleus. However, Hatton (1976) proposed that the nucleus circularis could be the actual osmoreceptor in the hypothalamus. The present study supported Hatton by using 30 rats which were randomly assigned to sham, lateral preoptic, and nucleus circularis lesion groups. After a 2-week post-operative period, half of each group was injected with isotonic saline while the other half was injected with hypertonic saline. … more

An Examination of a Framework for Posttraumatic Stress Disorder Correlates: Exploring the Roles of Narrative Centrality and Negative Affectivity

Description: Recent estimates suggest that a large percentage of the population experiences some type of traumatic event over the course of the lifetime, but a relatively small proportion of individuals develop severe, long-lasting problems (e.g., posttraumatic stress disorder; PTSD). One major goal for trauma researchers is to understand what factors contribute to these differential outcomes, and much of this research has examined correlates of posttraumatic stress disorder (PTSD) symptom severity. An impo… more

Handedness, Perceptual and Short Term Memory Asymmetries, and Personality

Description: A large body of research has depicted relative arousal of the left and right cerebral hemispheres as related to utilization of particular defensive coping styles, level of anxiety, and perceptual styles. The right and left hemispheres are also presented in the literature as differing in visual-spatial and verbal-auditory short term memory abilities. The present research studied 127 right handed undergraduates' relative performance on forward spatial and digits memory spans in relation to hemis… more

Intersecting Identities and Conflict as Moderators of the Relationship Between Discrimination and Mental Health in Emerging Adulthood

Description: Individuals with a minority sexual identity, such as lesbians, gay men, and bisexuals (LGB) face increased risk for stigmatization surrounding their sexual identities and subsequent psychological distress. Sexual minorities of color (SMOC) face the same difficulties faced by White sexual minorities, often compounded with stigma and discrimination linked to their racial/ethnic identities. However, because SMOC remain underrepresented in research on LGB issues, empirically-driven knowledge abou… more

Is Mind Wandering the Mechanism Responsible for Life Stress Induced Impairments in Working Memory Capacity?

Description: The relationship between life stress and working memory capacity (WMC) has been documented in college students and older adults. It has been proposed that intrusive thoughts about life stress are the mechanism responsible for the impairments seen in WMC. To examine the mechanism responsible for these impairments the current study attempted to induce intrusive thoughts about personal events. The current study allowed for a test of predictions made by two theories of mind wandering regarding the … more

Learned Helplessness: Effect on Working Memory and Fluid Intelligence

Description: To determine if learned helplessness treatment debilitates human working memory and fluid intelligence, 60 university students, classified as high or low self-monitors, were assigned to one of three treatments: intermittent (50%) controllable positive feedback, uncontrollable (yoked) negative feedback, and no treatment. Test tasks included backward digit and backward spatial span (representing working memory), matrices (representing fluid intelligence), vocabulary (representing crystallized int… more

Learned Helplessness: The Result of the Uncontrollability of Reinforcement or the Result of the Uncontrollability of Aversive Stimuli?

Description: This research demonstrates that experience with uncontrollable reinforcement, here defined as continuous non-contingent positive feedback to solution attempts of insoluble problems, fails to produce the proactive interference phenomenon, learned helplessness, while uncontrollable aversive events, here defined as negative feedback to solution attempts of insoluble problems, produces that phenomenon. These results partially support the "learned helplessness" hypothesis of Seligman (1975) which pr… more

The Organizational Socialization of a Dynamic Workforce: A Focus on Employee and Contract Worker Knowledge Transfer

Description: Within the last decade, more organizations are utilizing a non-traditional workforce. Specifically, these organizations are utilizing contract workers as resources to provide services and manufacture products. While this change in workforce provides benefits to organizations, the change also presents numerous challenges such as turnover. The turnover involved in such a relationship along with the addition of newcomers translates into an organizational socialization and knowledge transfer (KT) i… more

An Osmoreceptive Zone Around the Nucleus Circularis

Description: The nucleus circularis has been linked to a role in regulating osmotic thirst but evidence has also shown that full bilateral destruction of the nucleus circularis was not necessary to achieve a deficit in drinking behavior after an osmotic challenge. The present study attempted to answer two primary research questions. The first question was whether osmoreceptive cells existed around the nucleus circularis in a homogeneous fashion or if these cells existed in a structured fashion stretching fr… more

Patterns of Relationship Violence among Low Income Women and Severely Psychologically Abused Women

Description: Little research has addressed the degree to which domestic violence is mutual and whether patterns are stable across women's relationships. Studies that exist have conflicting results. This study addressed these issues and the effects of sustaining past violence on women's expressions of violence in their current relationship. Archival data from a sample of severely psychologically abused community women (N = 92) and a sample of low-income community women (N = 836) were analyzed. Results showed… more

Police Attitudes Toward Rape

Description: Research has demonstrated that the general public accepts many rape myths and that rape attitudes are strongly connected to other deeply held and pervasive attitudes. However, it has not been clear whether police officers reflected similar attitudes. This research attempted to ascertain if police share the same antecedents of rape myth acceptance as the general public. Using officers from two police departments, it was demonstrated that attidudes regarding sex role stereotyping, sexual conserva… more

The Relationship between Team Leader Behaviors and Team Performance and Satisfaction

Description: The purpose of this study, a quasi experimental design, was to investigate the relationship between team leader behavior and team performance and satisfaction. This field research tested leader behavior dimensions from two theoretical models of team effectiveness: Hackman's (1992) "expert available coaching," and Cohen's (1994) "encouraging supervisory behaviors." The relationship between coaching behaviors and team performance, employee, and customer satisfaction was assessed. Manager behavior… more

The Relationship of Self-Monitoring to Team Leader Flexibility and Work Environment Preference

Description: This research explores the relationship of self-monitoring with team leader behavior and work environment preference. Those who are high on self-monitoring demonstrate flexibility in their actions with others and are socially perceptive. They perform well in a variety of leadership positions and are viewed as leaders by group members. High self-monitoring types choose "socially" based careers, including teacher and psychologist, in which they adapt their interaction styles to effectively mee… more

Response to Sexual Trauma in Relation to Event Centrality and Objectified View of Self

Description: This study examined the potentially differing emotional consequences of sexual versus non-sexual traumas in both a student and a community residing treatment seeking sample of women. The extent to which a trauma survivor considers the traumatic event central to her identity (CES) was examined as a potential mediator between traumatic events and PTSD. Additionally, the extent to which a women views herself and her body as a sexual object, to be valued based on her appearance and sexual usefuln… more

Sex Differences in Performance Expectancies

Description: Previous research demonstrates expectations predict actual performance. These studies evaluated the influence of other variables, specifically task sex orientation, biological gender, and sex-role identification, on performance expectancies. Two studies investigated sex differences in performance expectancies: Study 1 used a task normatively favoring males; Study 2 used a task normatively unbiased by gender. Subjects were 207 undergraduates, approximately equal numbers of males and females. Exp… more

Structural Aspects of Loevinger's Model of Ego Development

Description: The study reviews the structural and psychometric underpinnings of Loevinger's theory of ego development. It is noted that the current literature investigating the validity of Loevinger's model has not adequately addressed the structural assumptions of the theory. "Process" variables are hypothesized to vary depending on the process of structural change. Two such variables, cognitive complexity and the organization of cognitive constructs, were measured in 73 college students, staff, and facult… more

Tachistoscopic Versus Free Inspection Presentation of the Müller-Lyer Illusion

Description: This study was designed as an attempt to extend Schneider and Shiffrin's (1977) automatic versus controlled processing distinction into the area of visual perception. Hasher and Zacks (1979) proposed a continuum of automatic processes, with processes which encode the fundamental aspects of the flow of information as the anchor of the continuum. They presented evidence that depressed people perform more poorly than nondepressed on effortful (controlled) memory tasks, but not on automatic tasks. … more
