Three experiments involved college students receiving and following instructions of various lengths for navigating in a three-dimensional space displayed on a computer screen. The purpose was to evaluate which is the best modality for presenting navigation instructions so that they can be executed successfully. Single modalities (read, hear, and see) were considered along with dual modalities presented simultaneously or successively. It was found that when there were differences between single modalities, generally execution accuracy was best for see and worst for read. Information presented in two modalities did not yield better accuracy than information presented twice in a single modality. Also, the ordering of modalities depended on the extent of practice. Thus, presentation modality does not have a consistently large effect on receiving and following navigation instructions. Repetition and the amount of practice are much more important variables than is presentation modality in determining how well navigation instructions are followed.  相似文献

The authors evaluated the role parent–child relationship quality has on two types of memories, those of parents and those of friends. Participants were 198 Italian university students who recalled memories during 4 separate timed memory-fluency tasks about their preschool, elementary school, middle school, high school and university years. Half were instructed to recall memories involving parents and the remainder memories involving friends. Moreover, parent–child relationships were assessed by the Network of Relationships Inventory (NRI; W. Furman & D. Buhrmester, 1985) and Adolescents’ Report of Parental Monitoring (D. M. Capaldi & G. R. Patterson, 1989). Results showed that men with positive parent–son relationships had more memories of parents and more affectively positive memories of friends, supporting a consistency model positing similarity between parent–child relationships and memories of friends. Women with positive parental relationship quality had more affectively positive memories of parents but for friends, positive relationship quality only predicted positive memories when young. At older ages, especially middle school-aged children, negative parent–daughter relationships predicted more positive memories of friends, supporting a compensatory model. The gender of parent also mattered, with fathers having a more influential role on affect for memories of friends.  相似文献

This study first explored the adequacy of items on the Rorschach Rating Scale (RRS), which measures Rorschach constructs from a variety of scoring systems. Analyses determined that all items had an adequate capacity to differentiate people and none were clearly redundant. At the same time, the current version of the RRS requires good reading comprehension skills for accurate completion (13th grade level). Next, we developed two sets of RRS scales. Factor analysis of observer ratings (N = 234) indicated the RRS contained six broad, empirically derived factors. In addition, 19 conceptually derived scales were developed from the RRS item pool. Both sets of scales were evaluated for reliability and then compared to the Big Five model (B5M) of personality through a series of factor and regression analyses. Results indicated that RRS scales do not provide adequate definition of all B5M dimensions and B5M scales do not provide adequate definition of all RRS dimensions. We discuss the place of psychotic processes within a comprehensive model of personality and other implications from these findings.  相似文献

Spatial working memory (SWM) is known to be impaired in children with ADHD-CT, whether anxiety is present or not. Yet, it remains unclear whether anxiety disorders add to the SWM impairments evident in ADHD-CT and whether these findings extend into adolescents with ADHD-CT and anxiety. Further, it is not yet known whether children and adolescents with carefully defined anxiety disorders alone, demonstrate SWM deficits. This study explored the association of SWM and its strategy and spatial span components in carefully defined children and adolescents (age 6–16 years) with ADHD-CT alone (N?=?163; 14 % female), ADHD-CT and anxiety (N?=?243; 23 % female), anxiety disorders alone (N?=?69; 25 % female) compared to age- and gender-matched healthy control participants (N?=?116; 19 % female). The relationship between SWM and its strategy and span components and core ADHD-CT symptoms and anxiety symptoms were also examined. There was no evidence of an additive effect of ADHD and anxiety on SWM, strategy and spatial span deficits. But, anxiety disorders alone were associated with impaired SWM and span performance compared to healthy control participants. In contrast, strategy did not differ between children and adolescents with anxiety disorders alone and healthy control participants, suggesting that with anxiety span is the most affected component. Further, these findings were age-independent. This study concurs with and extends current influential models about the cognitive effects of anxiety on performance in the setting of ADHD-CT. Clinical implications and future research directions are discussed.  相似文献

In this analog study, 104 female and 75 male undergraduate students in the United States read 1 of 8 vignettes that described a person who had just received positive HIV antigen results. The vignettes were identical except for the sex of the person described and his or her risk-group membership (gay, heterosexual, injection-drug user, or hemophiliac). After reading the vignette, the participants completed questionnaires assessing (a) responsibility, blame, and personality characteristics of the person described in the vignette; and (b) their own homophobia and knowledge about AIDS. Results revealed that homophobia was a significant covariate that affected participants' perceptions of the person in the vignette. with homophobia as a covariate, the hemophiliac was judged the least harshly, followed by the heterosexual person, the gay person, and the injection-drug user. No gender differences were revealed. The injection-drug user was evaluated the most negatively on the personality characteristics; the other 3 groups were rated similarly. Analyses without homophobia as a covariate revealed significant gender differences, suggesting that prior research findings of gender differences on perceptions of persons with AIDS may be attributable more to differential levels of homophobia than to gender of the rater.  相似文献

This study examined the factor structure, and differential item functioning of the Depression Anxiety Stress Scales (DASS; Lovibond & Lovibond, 1995) across sex. The DASS was completed by 201 women and 165 men from the general community. Confirmatory factor analysis (CFA) indicated support for the original 3-factor oblique model (factors for depression, anxiety and stress). There was however more support for a bifactor model, with four orthogonal factors: a general factor on which all the depression, anxiety and stress items load, and specific independent factors for depression, anxiety and stress items. None of the DASS items showed DIF. The practical, theoretical, research and clinical implications of the findings are discussed.  相似文献

This study examines teachers' beliefs about themselves as literate people and how those beliefs translate into classroom literary practice. Using a multi-method approach, it explores the private literate selves (via diary, survey, and interviews) of twelve K–12 teachers and establishes a foundational understanding of the influence of the social and personal nature of literacy on teacher support for literacy in the classroom and how teachers' personal literacy practices are made public to classroom learners. Results indicate that literacy played an important functional role in the lives of all 12 teachers. There was variability in the prominence of literacy for pleasure in the teachers' lives. In addition, there was variability in whether and in what ways teachers made their literacy practices public for their students. Implications for teacher education and professional development programs are offered.  相似文献

Objective: Fatigue, depression, anxiety, and executive dysfunction are associated with multiple sclerosis (MS) in adults. Existing research suggests similar problems in pediatric MS, but relationships between these variables have not been investigated. This study investigates the associations between executive functioning and fatigue, emotional functioning, age of onset, and disease duration in pediatric MS.

Methods: Twenty-six MS or Clinically Isolated Syndrome (CIS) patients, ages 7 to 18, were evaluated through a multidisciplinary demyelinating diseases clinic. Participants completed neuropsychological screening including Verbal Fluency, Digit Span, and Trail-Making Test. Parents completed rating forms of behavioral, emotional, and executive functioning. Patients and parents completed questionnaires related to the patient’s quality of life and fatigue. Pearson’s correlation coefficients were calculated to investigate relationships between fatigue, emotional functioning, and executive functioning, as well as to examine correlations between parent and child reports of fatigue.

Results: Rates of parent-reported anxiety, depression, fatigue, and executive dysfunction varied widely. Means were below average on the Trail-Making Test and average on Verbal Fluency and Digit Span, though scores varied widely. Various fatigue and emotional functioning indices—but not age of onset or disease duration—significantly correlated with various performance-based measures of executive functioning.

Conclusion: Results indicate pediatric MS is associated with some degree of fatigue, emotional difficulties, and executive dysfunction, the latter of which is associated with the two former. Notably, age of onset and disease duration did not significantly correlate with executive functioning. Results advance understanding of psychological and clinical variables related to neurocognitive outcomes in pediatric MS.  相似文献

Academic library collections are maintained to support programs and research at their home institutions. Information literacy, the formal instruction in the use of library resources, has become one of the essential programs in higher education. There is little research that shows how collection development, information literacy, and religious studies programs can be coordinated to produce successful partnerships. The authors, coordinators of Information Literacy and Collection Development, examined the religion collection, including purchase, usage, and circulation statistics. Information literacy courses in relation to the religious studies program were also investigated. After analyzing this data, the authors identified challenges, as they exist at their home institution, which includes a deficiency in both the religion collection and information literacy classes taught for the religious studies program. The authors conclude that much work is needed to advance successful collaborations between libraries and the religious studies departments, and academic librarians will need to examine their own religion collections to address similar challenges.  相似文献
