Response Guided Errorless Learning with Normal Elderly (open access)

Response Guided Errorless Learning with Normal Elderly

This study investigates the use of response guidance for errorless learning of a perceptual motor task in normal elderly. It provides normative data for a study with stroke patients using this technique for cognitive rehabilitation. While errorless learning has been shown to be more effective on most tasks than trial and error learning for people with memory impairments, its use with normal individuals has received limited attention. The questions of interest were whether errorless training of the perceptual motor task was more effective for improving and retaining accuracy; and whether both accuracy and response speed were more resistant to the effects of increased cognitive demands. A sample of 43 normal elderly in the United Kingdom, ranging in age from 60 to 77, completed an assessment of intelligence, memory, and attention. They then received training, over two sessions one week apart, to mark the midpoint of Judd Arrows presented on a computer screen using a cross cursor moved by an active force feedback joystick (AFF). During training the errorless group received AFF guidance to the correct midpoint, while the errorful group received none, and both received auditory and visual knowledge of results. There was no AFF during baseline or post test …

Masculine Gender Role Conflict and Psychological Well- Being: A Comparative Study of Heterosexual and Gay Men (open access)

Masculine Gender Role Conflict and Psychological Well- Being: A Comparative Study of Heterosexual and Gay Men

Masculine gender role conflict (MGRC) occurs when externally-imposed male gender role expectations have a negative impact on and consequences for men. The purpose of this study was to examine how men in a homogeneous setting (i.e., a college campus) compare on MGRC and psychological well-being, based on their self-identified sexual orientation. Utilizing canonical correlation analysis, 96 heterosexual men and 102 gay men were compared on four factors of MGRC (conflict between work and family, restrictive emotionality, restrictive affectionate behavior between men, and success, power, and competition) and five factors of psychological well-being (anger, anxiety, depression, self-esteem, and attitudes toward seeking psychological help). Findings for the heterosexual men were highly consistent with previous studies on MGRC and psychological well-being in a college-age population. Findings for the gay men indicated they had more problems with MGRC and psychological well-being than college-age and older gay men surveyed in the one published study on gay men and MGRC. Gay men who were single also reported more problems with restrictive emotionality, anger, anxiety, and depression, and had lower self-esteem, than gay men who were in a relationship. Between group differences were few, with gay men reporting significantly less restrictive affectionate behavior between men than heterosexual …

The mediating and moderating effects of women's attachment style on interrelationships among emotional abuse, physical aggression and relational stability. (open access)

The mediating and moderating effects of women's attachment style on interrelationships among emotional abuse, physical aggression and relational stability.

This purpose of this study was to combine two bodies of literature on relationships, attachment and violence. Given the impact of men's physical aggression and emotional abuse on women, it is likely that these behaviors would also affect attachment. A model proposing that women's attachment style mediated and moderated the relationship between partners' physical and emotional abuse and the stability of women's relationships was tested. Archival data were used from two waves of interviews with a sample of lowincome, ethnically diverse community women. Most (89%) of the initial 835 participants of Project HOW: Health Outcomes of Women completed at least one additional interview providing information on the status of their initial relationships. Of these women, 39% were African American, 30% were Euro-American, and 31% were Mexican American. The effects of men's psychological abuse and physical violence on women's attachment style were tested with regression analyses. The interrelationships between partners' abuse, attachment and relational stability were tested with SEM. Attachment style was expected to moderate the associations among variables and mediate the impact of partners' negative behavior on relational stability. In regression analyses, partners' psychological abuse predicted avoidant and anxious, but not secure attachment ratings. Violence, although significant, explained less variance …

Historical Changes in Elderly Cohorts' Attitudes toward Mental Health Services (open access)

Historical Changes in Elderly Cohorts' Attitudes toward Mental Health Services

Older adults' attitudes toward mental health services have received little research attention. Overall, older adults are thought to hold relatively negative attitudes. In this study, Analysis 1 investigated historical shifts in attitudes toward mental health services among three independent samples of older adults, separated by 14-year and 9-year intervals (1977 sample, N = 90; 1991 sample, N = 101; 2000 sample, N = 99). Analysis 2 compared two samples of older and younger adults, each separated by a 9-year interval (Older Adults: 1991 sample, N = 93; 2000 sample, N = 91 and Younger Adults: 1991 sample, N = 131; 2000 sample, N = 147). Participants completed a questionnaire containing five, internally consistent scales assessing multiple dimensions of mental health attitudes (Openness, Biases, Range of Knowledge, Breadth, Help Seeking Attitudes). Analyses suggested that the 1991 and 2000 samples of older adults had more positive attitudes than did the 1977 sample. However, a sustained trend for more positive attitudes beyond 1991 was not seen. In fact, no differences existed between 1991 and 2000 samples with exception of two. Older and younger adults together had lower Biases and Breadth scores in 2000 than in 1991. Age effects, gender effects, and interactions were …

Leadership, Ascendancy, and Gender (open access)

Leadership, Ascendancy, and Gender

By the year 2000 women will constitute more than 50 percent of the workforce in the United States, yet their representation in top management and executive-level positions continues to hover in the single digits. This “glass ceiling,” which is conceptualized as limiting women's advancement into these roles, has been the subject of much debate and research over the last fifteen years. As both an equal rights and key competitive issue, the topic of women and leadership is gaining ever-increasing emphasis and momentum in American corporations. Although leadership skills have been advocated as a key human capital/person-centered variable leading to managerial ascendancy for women, the empirical research directly investigating this link is virtually non-existent. This longitudinal study proposed to measure the strength of this relationship using a matched sample of male and female managers. Eighty-five subjects, from the same U.S. based health-care products corporation, had previously participated in a multirater assessment process where seven different facets of their leadership skills were evaluated. Time two data were collected on four objective measures of ascendancy: percent change in salary, number of promotions (job moves) either offered or accepted, change in number of direct reports, and change in number of indirect reports. Multivariate analysis …

Psychological Hardiness and Biochemical Markers of Acute Stress (open access)

Psychological Hardiness and Biochemical Markers of Acute Stress

The establishment of physiological norms for psychologically hardy vs. non-hardy individuals was attempted by examination of levels of salivary cortisol and urinary norepinephrine before and after a mid-term examination stressor. Normative data was collected on the reported frequency of stressors and their severity one week prior to the examination, and self-reported ratings of stress immediately prior to the examination. Performance on the examination as a function of hardiness was explored. Associations between demographic variables and psychological hardiness were also studied. Results from this study were inconclusive in establishing physiological norms for psychologically hardy individuals. Associations were found between: 1) hardiness and frequency of stressors; 2) hardiness and age; and 3) self-reported ratings of stress and anxiety as measured by the State-Trait Anxiety Inventory (STAI).

Multiple Predictors of College Adjustment and Academic Performance for Undergraduates in Their First Semester (open access)

Multiple Predictors of College Adjustment and Academic Performance for Undergraduates in Their First Semester

College success, as defined by adjustment to college and academic performance, is a multidetermined with a number of contributing influences, including academic factors, personality variables, family characteristics, and environmental factors. This study attempted to provide an organizing model of the college success literature that was based on previous research (e.g., Aspinwall & Taylor, 1994) and current stress-coping theory (Moos & Swindle, 1990). Structural equation modeling analyses indicated that the hypothesized model did not fit the data well. However, subsequent regression analyses did validate the view that college success is multidetermined. Specifically, academic performance was predicted by a combination of academic factors (SAT score and class rank) and academic adjustment. In turn, academic adjustment was predicted by locus of control, perceived social support, and high school class rank. Personal adjustment was predicted by coping strategies employed, parents who fostered autonomy, locus of control, self-esteem, and high school class rank. Finally, social adjustment was predicted by optimism, coping strategies employed, and locus of control. Treatment implications as well as directions for future research were discussed.

Simulating Statistical Power Curves with the Bootstrap and Robust Estimation

Access: Use of this item is restricted to the UNT Community
Power and effect size analysis are important methods in the psychological sciences. It is well known that classical statistical tests are not robust with respect to power and type II error. However, relatively little attention has been paid in the psychological literature to the effect that non-normality and outliers have on the power of a given statistical test (Wilcox, 1998). Robust measures of location exist that provide much more powerful tests of statistical hypotheses, but their usefulness in power estimation for sample size selection, with real data, is largely unknown. Furthermore, practical approaches to power planning (Cohen, 1988) usually focus on normal theory settings and in general do not make available nonparametric approaches to power and effect size estimation. Beran (1986) proved that it is possible to nonparametrically estimate power for a given statistical test using bootstrap methods (Efron, 1993). However, this method is not widely known or utilized in data analysis settings. This research study examined the practical importance of combining robust measures of location with nonparametric power analysis. Simulation and analysis of real world data sets are used. The present study found that: 1) bootstrap confidence intervals using Mestimators gave shorter confidence intervals than the normal theory counterpart …
