- Concurrent Validity of the Wide Range Assessment of Memory and Learning and the Woodcock-Johnson Tests of Cognitive Ability-Revised with a Neurologically Compromised Pediatric Population
- The Wide Range Assessment of Memory and Learning (WRAML) is a relatively new instrument used in the assessment of memory in children. The purpose of this study was to examine the validity of the WRAML by comparing the performance of children on both the WRAML and the Woodcock-Johnson Tests of Cognitive Ability- Revised (WJTCA-R). Subjects for the study were children in treatment for a brain tumor at a regional children's medical center. Fifty children participated in the study ranging from ages 6 to 17. A multiple regression analysis was conducted to determine which of four selected clusters from the WJTCA-R would have the highest correlation with the Verbal Memory Index (VERI) from the WRAML. The Short-Term Memory (GSM) cluster had the highest correlation ( r = .82) as predicted. A Pearson's product-moment correlational analysis was conducted between the Visual Processing (GV) cluster from the WJTCA-R and the Visual Memory Index (VISI) from the WRAML. GV was found to have a high positive correlation ( r = .63) with VISI. A similar analysis was conducted between the Long-Term Retrieval (GLR) cluster from the WJTCA-R and the Learning Index (LRNI) from the WRAML. GLR was found to have a high positive correlation ( r = .81) with LRNI. Finally, a correlational analysis was conducted between the Broad Cognitive Ability (BCA) scale from the WJTCA-R and the General Memory Index (GENI) from the WRAML. A high positive correlation ( r = .87) was found between these most global measures from the two batteries. The observed correlation between BCA and GENI was much higher than anticipated. The author concluded that neurological impairment had affected subject memory and intellectual functioning in similar ways. The results do not generalize to children who have not had similar decrements in cognitive functioning. Future research should establish a baseline …
- Differentiation of Central Auditory Processing Disorder and Attention-Deficit Hyperactivity Disorder in Children and Adolescents
- The purpose of this study was to determine whether or not children diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD) or Central Auditory Processing Disorder (CAPD) can be distinguished from one another on the basis of both objective and subjective assessment of attention and behavior. First, children and adolescents diagnosed with ADHD, CAPD, and concomitant ADHD/CAPD were compared to participants with emotional problems on measures of attention/concentration, depression, anxiety, and parental reports of internalzing and externalizing behaviors. Overall, statistical analyses did not reveal significant differences between performances of children diagnosed with ADHD and those diagnosed with CAPD. However, clinical comparisons across groups of children diagnosed with ADHD, CAPD, comorbid ADHD/CAPD and Affective Disorders revealed condition-specific clinical profiles, thus providing some support for CAPD as a distinct clinical entity. Second, exploratory cluster analysis was performed to further investigate the relationship between ADHD and CAPD. This procedure lead to the identification of four distinct clusters. However, analyses of these clusters revealed no distinct pattern of performance for children diagnosed with either ADHD or CAPD. Rather, participants with these diagnoses were evenly distributed throughout the clusters. Additionally, no cluster clearly represented the expected clinical profile for a diagnosis of CAPD- namely, significant auditory attentional/processing problems in the absence of other attentional difficulties. Implications for the assessment and treatment of childhood attentional disorders are discussed and recommendations for future research provided.
- The Effects of Media Exposure on Body Satisfaction, Beliefs About Attractiveness, Mood and Bulimic Symptomatology Among College Women
- The research of Stice et al. (1994) and Stice and Shaw (1994) proposed several mechanisms that may mediate the adverse effects of media exposure to the thin ideal including internalization of the thin-ideal, negative affect, and body dissatisfaction. The purpose of this study was to extend initial research of Stice and Shaw (1994) by incorporating two forms of media (e.g., TV and Magazines) to assess the effects of exposure to the media portrayal of ideal body shape on women's mood, body satisfaction, and internalization of societal values concerning attractiveness. The relation of these variables to bulimic symptomatology was examined. The current study improved upon Stice and Shaw's study (1994) by matching participants' scores on BMI, level of negative affect, and level of body satisfaction before random assignment to the experimental conditions. Female undergraduates aged 18 to 25 years participated in premeasure (N = 198) and post measure (N = 164) conditions. Results from repeated mulitvariate analysis indicated media exposure to ideal-body images demonstrated no significant changes in women's affect, body satisfaction or endorsement of the thin ideal. Indirect support for the sociocultural theory of eating disorders was provided by multiple regression analyses that demonstrated lower levels of satisfaction with size and shape of body and higher levels of negative affect predicted bulimic symptomatology in women. Future research should determine which females are at greater risk than others for the development of body dissatisfaction, negative mood, and internalization of U.S. values of attractiveness in response to media related messages communicating a thin ideal.
- The Interface of Personality Processes and Cognitive Abilities: A Comparative Study of Elderly and Young Adults
- Although research has shown that the complex constructs of intelligence and personality are necessarily intertwined, studies exploring this issue in elderly individuals are rare. The importance attached to this interface in older adults becomes particularly clear in light of the debate over the cause and extent of age-related decrements in cognitive performance as well as whether such losses can be ameliorated or not, especially given societal shifts toward increased life expectancies. The present study explored the basis for shifts in personality-ability relationships in adulthood by comparing two samples of older adults, one of which was assessed in 1975 (N = 102, M age = 68.4), and the second of which was assessed in 1995 (N = 100, M age = 72.0), and a sample of younger adults (N = 100, M age = 21.8), also assessed in 1995. Each participant was administered the Holtzman Inkblot Technique and the Gf-Gc Sampler, a measure of crystallized (Gc) and fluid (Gf) abilities. LISREL analyses of both age-related and historical shifts in personality-ability relationships suggested that not only were such shifts associated with cohort differences as reflected in factor loading (lambda) differences between the older samples and the younger sample, as well as between each of the older samples, but also that such connections were weaker among younger adults. These findings are important in revealing that sociocultural shifts in opportunities for continued cognitive growth influence the impact of noncognitive (personality) factors on intellectual functioning in later life. Limitations of the current study, implications of the results, and suggestions for future research are discussed.
- Perceived Attractiveness and Personality Attributes: A Gender and Racial Analysis
- Subjects rated 12 female body shapes with respect to their physical attractiveness, and the extent to which they would be expected to possess various personality characteristics. The shapes were varied using 3 levels of overall weight and 4 levels of body shapeliness. The sample was modified to control for socioeconomic factors and results are based on 297 undergraduates from Caucasian, African American, and Hispanic racial backgrounds. Loglinear analyses revealed that men and women, regardless of racial background, rated shapely underweight females as most physically attractive, sexy, and ideal for a woman, followed by normal weight figures of similar proportion. African Americans, women in particular, judged the shapely normal weight figures more favorably than the other subjects. Multidimensional scaling and subsequent frequency analyses showed that those figures judged as most attractive, sexy, and ideal were also expected to be fairly emotionally stable, and most successful and interpersonally competitive, but least faithful, kind, and family-oriented. Overweight female shapes, while rated as least physically attractive, sexy, and emotionally stable, were expected to be most family-oriented, kind, and faithful. Shapely normal weight figures were judged to be attractive and sexy, and were assumed to possess a moderate amount of the personality traits in question. The results suggest that Caucasian and Hispanic subjects prefer shapely underweight women, while African Americans, particularly women, find shapely underweight and shapely normal weight women to be physically appealing. African American women also rate shapely normal weight women favorably with respect to personality traits. This perceptual difference may help inoculate them from developing eating disturbances and account for the low prevalence rate of eating disorders in African Americans compared to women of other racial backgrounds. It is suggested that future research identify those beliefs, values or behaviors that seem to inoculate African American women from developing eating disorders. Once identified, …
- Performance Measurement, Feedback, and Reward Processes in Research and Development Work Teams: Effects on Perceptions of Performance
- Organizations have had difficulty managing the performance of their knowledge work teams. Many of these troubles have been linked to antiquated or inadequate performance management systems along with a scarcity of empirical research on this important human resource initiative. These problems are magnified when managing the performance of research and development teams because greater ambiguity and uncertainty exists in these environments, while projects are unique and continually evolving. In addition, performance management in R&D has only recently been accepted as important while individuals in these settings are often resistant to teams. This study represented the first step in the process of understanding relationships between performance management practices and perceptions of performance in R&D work teams. Participants were 132 R&D team leaders representing 20 organizations that agreed to complete a survey via the Internet. The survey instrument was designed to examine the relationships between performance measurement, feedback, and reward processes utilized by teams in relation to measures of customer satisfaction, psychological and team effectiveness, and resource utilization and development. The most important level of performance measurement occurred at the business unit level followed next by the individual level while team level measurement was unrelated to team performance. A simple measurement system with three to seven performance measures focused on objective results, outcomes, and customer satisfaction appeared ideal. Team participation in the performance management process, most notably the process of setting performance measures, goals, and objectives was also important. The use of multiple raters, frequent performance appraisals, and frequent feedback were identified as meaningful. Specific types of rewards were unrelated to performance although some evidence suggested that business unit rewards were superior to team and individual rewards. It was speculated that R&D teams function more like working groups rather than real teams. The focus in R&D seems to be on business unit …
- Prevalence of Undiagnosed Dissociative Disorders in an Inpatient Setting
- This study examined the prevalence of undiagnosed dissociative disorders in a sample of 201 adult patients admitted to a private psychiatric hospital in a major metropolitan city in the south-central United States, over an eight-month period. A screening measure, two blind structured interviews, and a blind clinical interview were employed. The lifetime prevalence of dissociate disorders among the interviewed subjects was 40.8%. More specifically, 7.5% were diagnosed with dissociative identity disorder, 15.4% with dissociative disorder not otherwise specified, 13.4% with dissociative amnesia, and 4.5% with depersonalization disorder. Dissociative fugue was not found in this sample. Cohen's kappa reliability coefficients were computed between the three interview measures, resulting in significant findings for the presence of dissociative identity disorder and dissociative disorder not otherwise specified versus no dissociative disorder. The Cohen's kappa reliability coefficients were as follows: DDIS-DES-T = 0.81; SCID-D-DES-T = 0.76; Clinician-DES-T = 0.74, DDIS-SCID-D = 0.74; DDIS-Clinician = 0.71, and SCID-D-Clinician = 0.56. A meeting was conducted at the end of all subject interviews to discuss discrepant findings between measures. Four additional sub-analyses were performed between dissociative and non-dissociative subjects on DSM-IV variables. Patients diagnosed with a dissociative disorder had higher rates of comorbid major depressive disorder, borderline personality disorder, somatization disorder, and childhood history of physical and/or sexual abuse. Theoretical and methodological issues were discussed as they relate to these findings.
- The Relationship of Parental Attachment, Peer Attachment, and Self-Concept to the Adjustment of First-Year College Students
- The transition to college is usually the first time many late adolescents live apart from their parents for an extended period, making it an important developmental task (Kenny, 1987) that requires a variety of adaptational resources. Bowlby's (1969/1982, 1973, 1980) attachment theory has been refined by Kenny and Rice (1995) to explain how internal working models of late adolescents are the bases of the adaptational resources that determine the quality of adjustment to college. The Kenny and Rice model may be interpreted to suggest that external resources should include relationships with parents and friends, while internal resources can include self-concept. According to the authors, "these resources are assumed to moderate or buffer the effects of developmental challenges and stressful events on adjustment" (p.437). The purpose of the present study was to extend and further clarify the ways that quality attachment relationships and positive self-concept conjointly may promote healthy adaptation in the college milieu. In particular, the present study examined the influence of self-concept as a mediating variable with respect to attachment and healthy adjustment to college. Students from Freshman Psychology classes completed measures to assess their attachment relationships with each parent, their attachment relationships with peers, their level of self-concept, and their perceived adaptation to college. These measures were completed by students of traditional age (ages 18-20) within the first year of starting college. The results of the study indicate that: 1) a relationship exists between attachment and self-concept; 2) attachment is associated with college adjustment; 3) self-concept is related to college adjustment, and functions as a mediator variable between attachment and college adjustment; 4) there were no gender effects in the levels of mother or father attachment, and females reported higher levels of peer attachment; and 5) there were no gender effects in overall levels self-concept, but females reported …
