Comparison of Visual and Auditory Continuous Performance Tests in Adults (open access)

Comparison of Visual and Auditory Continuous Performance Tests in Adults

Two continuous performance tests were administered to normal adult subjects. The mode of presentation (visual or auditory) and the type of task (vigilance or distractibility) were varied, and their effects on performance measured. Data were collected on eighty-two subjects, and results indicated that auditory presentation of stimuli increased the difficulty of both tasks. Results also suggest that the distractibility task administered in either mode was more difficult than the vigilance task. Intercorrelations among the four continuous performance tasks are provided. Normative data are presented on all four tasks administered. A measure of symptoms of attention-deficit disorder in adults, the Adult Behavior Checklist, was found to correlate significantly with another measure of pathology, the SCL-90-R.

Self-Complexity and Physiological Responses to Facial Self-Reflection: An Investigation into Women's Self-Image (open access)

Self-Complexity and Physiological Responses to Facial Self-Reflection: An Investigation into Women's Self-Image

In this study, effects of facial self-reflection and complexity of self on physiological responses were investigated. Skin conductance levels were measured during baseline and neutral conditions, then under a self-focusing condition provided by mirror reflection of the face. Subjects completed measures of self-complexity, depressive affect, self-esteem, anxiety and body image satisfaction. Eye tracking data was collected during the mirror condition. Results showed a significant effect of mirror self-reflection on physiological reactivity as measured by differences between mirror and baseline mean responses. Pre-test depressive affect was correlated with low self-esteem but not with self-complexity. Self-complexity was negatively correlated with orientation to physical appearance and positively correlated with greater differences between baseline and mirror mean reactivity. Self-complexity and depressive affect did not significantly predict physiological reactivity, although a trend was found for the influence of each variable. Post-hoc analyses showed significant group differences for both self-complexity and depressive affect on physiological reactivity, although the influence of self-complexity was in the unexpected direction. Results of this study are consistent with general findings that negative self-esteem, anxiety and depression are strongly correlated. In addition, a strong correlation was found between negative self-esteem and dissociative symptoms. Exploratory analyses of eye tracking data found no significant …

Problem Solving Cognitive Processes in Younger and Older Adults (open access)

Problem Solving Cognitive Processes in Younger and Older Adults

The purpose of the present study was to examine cognitive abilities and problem solving processes of young and older adults. Specifically, three areas of inquiry were investigated: possible age-related differences in problem solving cognitive abilities, possible differences in cognitive processes used during problem solution, and possible differences in determinants of problem solving cognitive processes.

The Relationship Between Abilities and Perceived Everyday Intelligence in Older Adults (open access)

The Relationship Between Abilities and Perceived Everyday Intelligence in Older Adults

This study examined the relationship between perceptions of intellectual functioning and measures of cognitive abilities, personality variables and sociodemographic information. One hundred and fifty-two older community residing adults were asked to define their perception of intelligence by completing a questionnaire that asked the extent to which a variety of tasks are: functionally important, contribute to feelings of intellectual vitality and are the object of worry or concern. They also estimated their skill at performing each task. The hypothesis that cognitive abilities would best predict perceptions of cognitive functioning was moderately supported. Personality variables, specifically anxiety, were more predictive of the meaning variables than abilities.

Personality Correlates of Anorexia Nervosa in a Nonclinical Sample (open access)

Personality Correlates of Anorexia Nervosa in a Nonclinical Sample

The purpose of this study was to examine the relationship between anorexia nervosa and several personality traits. Past research in this area has been contradictory for several reasons. Sociocultural theories have described the media's role in promoting eating disorders by portraying a thin body-type as the ideal. However, they have neglected to describe the personality ideal which our society promotes in women. It is proposed here that anorexics incorporate and oppose this ideal. Therefore, the anorexic personality is one filled with conflict.

First-Time Parenthood: Attachment, Family Variables, Emotional Reactions, and Task Responsibilities as Predictors Of Stress (open access)

First-Time Parenthood: Attachment, Family Variables, Emotional Reactions, and Task Responsibilities as Predictors Of Stress

The purpose of this study was to explore factors which are predictive of parenting stress for first-time parents. Based on attachment theory and empirical research, the factors investigated were the responsibility for child care and housework, the current and retrospective relationship with the family of origin, the change in emotions related to parenthood, the marital relationship, and attachment and individuation.

PTSD in Women following a Disaster: the Effects of Social Support and Gender Differences (open access)

PTSD in Women following a Disaster: the Effects of Social Support and Gender Differences

The purpose of this study was to examine and compare individuals that had survived a single incidence trauma, the Luby's massacre in Killeen, Texas. Participants answered questions regarding various facets of social support following the trauma, and were also screened for a diagnosis of PTSD. Participants' level of symptoms, specifically depression, anxiety, and phobic anxiety was measured over time with the SCL-90-R. The results of this study indicate that, while women initially experience a higher level of depression and phobic anxiety, there is no gender difference in rate of symptom change over time. This study also found that women were significantly higher than men on desirability, utilization and usefulness of social support. Of the target symptoms, however, only depression correlated with any facet of social support, specifically, desirability. Finally, this study questioned whether individuals would share more similarities with others based on gender or diagnosis. It is suggested by the current data that diagnosis is the better indicator of similarity.

The Influence of Separation, Attachment and Family Processes on the Career Exploratory Behavior of Late Adolescents (open access)

The Influence of Separation, Attachment and Family Processes on the Career Exploratory Behavior of Late Adolescents

The purpose of this study was to examine the idea that a late adolescent's career exploration activities may be influenced by levels of attachment to and psychological separation from family, family health, and family structure. It was proposed that higher levels of self and environmental exploration would be associated with positive family relationships and adequate levels of psychological separation and attachment. Cognitive and demographic variables were included as control measures. Measures of family health, attachment, separation, family structure, career exploration, career decision making self efficacy, and beliefs in the usefulness of engaging in self and environmental exploration were administered to 304 undergraduates from intact families. Multiple regression analyses were employed to examine the contribution of the independent variables measuring family processes to the variability in the dependent variables of self and environmental exploration, after controlling for the variability associated with the control measures. The demographic variables were age, gender, class standing, and decision status about a major. Results indicated that the best predictors of career exploration in late adolescence were the cognitive variables. Beliefs in the usefulness of self exploration were the best predictor of self exploration, whereas career decision making self efficacy was the best predictor of environmental exploration. …

The Process of Sharing Team Leadership : A Study of Key Leadership Behaviors and Who Exhibits Them

Using a manufacturing setting that is organized into self-managed teams, the current study identified and measured key leadership behaviors within the teams. Questions that were asked include: are some team leadership behaviors more critical to a team's level of functioning than other behaviors? and do successful self-managed teams rely on formal leadership to a lesser extent than members of less successful teams? These questions were asked in the context of leadership as a process, not an individual.
