Bidirectional effects between engaged lifestyle and cognition in later life: Exploring the moderation hypothesis for personality variables.

Bidirectional effects between engaged lifestyle and cognition in later life: Exploring the moderation hypothesis for personality variables.

Date: December 2009
Creator: Starkweather, Jonathan
Description: Longitudinal data (N = 263) was used to investigate the bidirectional relationship between engagement (engaged lifestyle activities) and cognition (crystallized & fluid intelligence). Extroversion and openness to experience were also tested as moderators of the relationship between engagement and cognition. Results showed that the relationship between engagement at Wave 1 and cognition at Wave 2 did not differ from the relationship between cognition at Wave 1 and engagement at Wave 2. Testing for moderation with regression indicated that neither extroversion nor openness was moderating the relationship between engagement and cognition in either direction. Structural equation models provided further summary evidence that the relationships among engagement at Wave 1, extroversion, openness, and cognition at Wave 2 were not strong. However, a strong limitation to these results was the measurement error associated with a new measure of engagement.

Consistency, Consolidation, and Cognition in Autobiographical Memories: a Flashbulb Memory Approach

Consistency, Consolidation, and Cognition in Autobiographical Memories: a Flashbulb Memory Approach

Date: May 2013
Creator: Kraha, Amanda
Description: Flashbulb memories are highly vivid and long-lasting memories for events that are emotionally significant and personally important. These memories are held in very high confidence in accuracy over an extended period. In particular, individuals believe that they can remember the personal details surrounding the event such as where they were and what they were doing at the time the event occurred. Evidence from research, however, indicates that this may not be the case. The study of flashbulb memories has typically been confined to negative events such as September 11, 2001. In the current study, we employ the methods of Talarico and Rubin (2003) to investigate flashbulb memory formation to a positive event. The event is the assassination of Osama bin Laden, which resonated as a highly positive event for many Americans evidenced by the thousands of people flooding the streets of Washington, D.C. and New York City to celebrate. We examined various memory properties over a one-year period, including vividness, rehearsal, belief in accuracy, and consistency. Results confirm the formation of flashbulb memories to the assassination event, but results did not support many of the proposed hypotheses. Some differences were found for different testing groups (i.e., immediate versus one week ...

Convergence of Self and Other Ratings of Personality: a Structural Equation Analysis

Convergence of Self and Other Ratings of Personality: a Structural Equation Analysis

Date: May 1998
Creator: McElhenie, Michael K. (Michael Keith)
Description: Recently, multi-source feedback has been a popular way of providing performance-related feedback to individuals in many organizations. Many who use multi-source feedback consider Rating Convergence, others seeing target individuals as they see themselves, to be a positive outcome of this process. However, the variables that account for Rating Convergence are not known. This study investigated whether the personality factor Extroversion and Behavioral Consistency, acting as a moderator variable, could account for Self-other Rating Convergence, particularly the Convergence between self and peer Ratings. The sample consisted of 235 mid-level managers from a variety of industries who were participants in individual career development workshops. Using structural equation modeling, the results indicated that a model consisting of a single Extroversion factor could account for the convergence of self-peer ratings. This finding calls into question the significance of Rating Convergence when using multi-source rating instruments that provide feedback on trait characteristics since it may be heavily influenced by a single personality factor rather than observers' comprehensive understanding of the ratee's performance.

Devaluing Stigma in the Context of Forgiveness, Coping and Adaptation: a Structural Regression Model of Reappraisal

Devaluing Stigma in the Context of Forgiveness, Coping and Adaptation: a Structural Regression Model of Reappraisal

Date: May 2012
Creator: Gates, Michael S.
Description: The 2010 National HIV/AIDS Strategy outlined three important goals for managing the current HIV pandemic in the U.S.: (1) reduce the number of people who become infected with HIV; (2) improve access to health care and health-related outcomes for people living with HIV/AIDS (PLH/A); and (3) reduce HIV-related health disparities. Each of these goals tacitly depends upon reducing HIV-related stigma, and this study examined how HIV+ individuals evaluate coping efforts to overcome stigma’s impact on quality of life (QOL). a structural regression model was developed to instantiate the reappraisal process described by Lazarus and Folkman’s transactional theory of stress and coping, and this model indicated that maladaptive coping fully mediated the relationship between dispositional forgiveness and perceived stigma, which supports the prediction that coping efficacy is related to stress reduction. Additionally, maladaptive coping fully mediated the relationship between dispositional forgiveness and QOL, supporting the contention that forgiveness is a critical aspect to the evaluative process that influences how PLH/A cope with stigma. Lastly, the model showed that when PLH/A engaged in maladaptive coping to mitigate stress-related stigma, these individuals experienced increased stigmatization and reported significantly lower levels of health-related QOL. in contrast, PLH/A that reported higher levels of dispositional forgiveness ...

The Effects Of The Allocation Of Attention Congruent With Lateralized Cognitive Tasks On EEG Coherence Measurements

The Effects Of The Allocation Of Attention Congruent With Lateralized Cognitive Tasks On EEG Coherence Measurements

Date: May 2002
Creator: Hill, Cynthia DeLeon
Description: The single task condition of the Urbanczyk and Kennelly (1991) study was conducted while recording a continuous electroencephalographic (EEG) record. Attention was allocated by instructed lateral head orienting and eye gaze either congruently or incongruently with lateralized cognitive tasks. Thirty university subjects retained a digit span or a spatial location span for a 20 second retention interval. EEG data were extracted from the 20 second retention intervals and interhemispheric coherence was calculated for homologous sites in the temporal, parietal and occipital regions of the brain. There was a main effect for group, with congruent orienting producing greater coherence values than incongruent orienting. This effect of attention on alpha coherence values was found in the low alpha (8-10 Hz) frequency band. This provides evidence that the lower alpha frequency band is reflective of manipulations of attention. The higher coherence measures for the congruent orienting group indicates that homologous regions of the two hemispheres are more coupled into a single system when lateralized attention activates the same hemisphere performing the cognitive task. In the higher alpha frequency band (11-13 Hz) group, sex, site and task interacted. This provides evidence that the higher alpha band is more affected by cognitive processing of the ...

Examining Employee Satisfaction, Customer Service and Customer Satisfaction in a Retail Banking Organization

Examining Employee Satisfaction, Customer Service and Customer Satisfaction in a Retail Banking Organization

Access: Use of this item is restricted to the UNT Community.
Date: May 2006
Creator: Simpson, Eric Phillip
Description: In the increasingly competitive world of retail banking, organizations are focusing their attention on customer service as a means of increasing customer loyalty and retention. With this goal of increasing customer retention, the link between the attitudes of the service provider (employee satisfaction), the customer interaction behaviors that those attitudes lead to (customer service quality), and the attitudes that those behaviors generate in the customer (customer satisfaction) has become an increasingly important area of investigation. The goal of this research is to analyze the relationships that exist between these three variables: employee satisfaction, customer service quality, and customer satisfaction in a mid-sized retail bank. Data from three separate surveys collected during the same time period in 137 branches of a regional bank are analyzed using multiple regression analysis to determine whether relationships and interactions exist at a banking center level. While results of the analyses did not show a significant relationship between the variables, issues relevant to this determination are discussed and conclusions drawn regarding the nature of these constructs.

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

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

Date: December 1997
Creator: Kavcic, Voyko
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 ...

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

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

Date: August 2011
Creator: Banks, Jonathan Britten
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 impact of these intrusive thoughts on WMC task performance. One hundred fifty undergraduates were assigned to a control group, positive event group, or negative event group. Participants in the positive and negative event groups completed a short emotional disclosure about an imagined future positive or negative event, respectively, to induce positive or negative intrusive thoughts. WMC measures were completed prior to and following the emotional writing. Results indicated a significant relationship between WMC and mind wandering, however the writing manipulation did not result in any consistent changes in intrusive thoughts or WMC. The results suggest a causal relationship between WMC and mind wandering. The emotional valence of the intrusive thought altered the impact on WMC. No relationship was seen between the measures of stress ...

A Longitudinal Examination of Factors Associated with Custodial Grandparenting: A Test of Moderated Mediation

A Longitudinal Examination of Factors Associated with Custodial Grandparenting: A Test of Moderated Mediation

Date: December 2009
Creator: Moske, Amanda Kay
Description: The purpose of this study was to explore the following relationships: (a) how moderating factors (gender, age, ethnicity, social support, marital status, reason for role assumption and number of grandchildren in the home) can influence the mediating role of resiliency, and (b) how resiliency may mediate the negative effects of raising grandchildren (role demands, life disruptions, and difficulties with grandchildren) on grandparent adjustment over time. Resiliency was hypothesized to have the greatest effect on custodial grandparents who experienced the most stress (i.e., older, single, Caucasian males lacking social support and raising more than one grandchild). Mediation was assessed using structural equation modeling. Results indicated resilience mediated the relationship between role assumptions (i.e., role demands and life disruptions) and grandparent adjustment; however, resilience did not mediate the relationship between grandchild characteristics and grandparent adjustment. Due to the small number of custodial grandfathers (n = 14), non-married grandparents (n = 29), non-Caucasian grandparents (n = 10), the small number of grandparents who assumed the custodial role for less ambiguous reasons (n = 24), and the number of custodial grandparents with more than one grandchild residing in the home (n = 29) participating within the study, hierarchical multiple regressions were only conducted to ...

The relationship of self-monitoring to team leader flexibility and work environment preference

The relationship of self-monitoring to team leader flexibility and work environment preference

Access: Use of this item is restricted to the UNT Community.
Date: August 2000
Creator: Nichols, Judith Ann
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 meet the demands of clients. The demands placed on a team leader appear to require similar characteristics to those that high self-monitoring individuals possess. As a team matures through different stages of development, the role of the leader ranges from director to facilitator to consultant. In order to effectively meet team needs, a leader must be socially sensitive to interpersonal cues and have the ability to assume various roles. In addition, given the fact that the position of team leader is a highly social type of career that requires behaviors similar to careers chosen by high self-monitoring individuals, it is likely that high self-monitors would prefer working in a team work environment over a traditional one. A survey methodology was used to assess the characteristics of 100 team members. No relationship ...
