Disruption of proofreading by irrelevant speech: Effects of attention,arousal or memory?

A series of five experiments examined the effects of irrelevant speech on proofreading and memory. Four of the experiments used a proofreading task and showed that the deleterious effects of irrelevant speech: (1) depend on the speech being meaningful, (2) are only present when the burden on short-term memory is low and (3) are manifested in a lower detection rate for non-contextual as opposed to contextual errors. Neither the spatial location of the speech (either in terms of spatial dispersion of sources or spatial movement of a single source) nor the intensity of the speech (in a range bounded by 50 dB(A) and 70 dB(A)) had any effect on proofreading. Late selection models of attention are favoured by the results in preference to models having arousal, short-term memory or early selection in attention as their basis. A final experiment showed serial recall for visual lists to be impaired by the presence of any speech-like sound (including reversed speech and speech in an unfamiliar language) which suggests a set of phenomena qualitatively different from those associated with proofreading. Throughout the article the practical consequences of the findings are emphasized.     

Safety locus of control and employees' accidents

This study further established the criterion-related validity of the Safety Locus of Control Scale. The safety scale was designed to predict employment applicants' propensity for on-the-job accidents. In this study, 283 hospital employees with moreexternal safety locus of control orientations reported significantly more occupational accidents, as well as more severe and costly injuries, than workers with moreinternal safety attitudes (p<.05 in all cases). Implications of these results are discussed.Research study presented at the 1988 Annual Conference of the Association of Human Resources Management and Organizational Behavior, Long Beach, California, October 26–29.     

Measuring the impact of informal caring

A factor-analysis of caregiving impact appraisals amongst a community-derived sample of informal carers of elderly people revealed two negative (care work strain and relationship dissatisfaction) and two positive (care work satisfaction and care lifestyle satisfaction) scales. Validity was assessed by means of concurrent correlations with levels of assistance with daily living tasks provided by carers and levels of behaviour problems exhibited by elderly dependents. Criterion validity was considered in relation to two important carer outcomes; willingness to care and a standardized measure of strain. Each of the four scales was significantly associated with concurrently assessed willingness to care. Care work strain and relationship dissatisfaction were associated with concurrently measured strain symptomology. Evidence of 6-month predictive validity was obtained for the care work strain scale.     

What's Stressful About Caring?1

Karasek's (1979) demand-discretion theory of job strain and satisfaction was tested in a cross-sectional survey of informal carers of elderly people (n= 108) identified from a preliminary screening survey. The theory was largely supported by the findings. Multivariate analysis of variance showed that carer well-being and satisfaction with caring work were predicted by high levels of demand arising from the needs of elderly dependents and the interaction of high demands with discretion over meeting demands. The results allow some clarification of previously inconsistent findings from caregiver well-being research and have implications for the design of services to relieve carers of the burden of care.     

Reducing adverse reaction to stress in the workplace. Psychology's expanding role

This section draws attention to occupational stress and suggests ways in which psychologists can apply their knowledge of research methods and treatment to this issue. In this article, the past and present role of psychologists in occupational stress is examined and ways in which psychologists might play a more central role are proposed. Although industrial/organizational and health psychology are most obviously applicable to the study of workplace wellness, more focused attention and wider application of knowledge from other subspecialities are also examined. The need for increased attention to work and family; race, class, and gender; and training and public policy issues are also discussed.     

Efficacy of behavioral management and patient education on vascular access cleansing compliance in hemodialysis patients

Compared four treatment conditions to test their ability to enhance compliance with vascular access cleansing (VAC) procedures in a group of 56 hemodialysis patients. The conditions were patient education, behavioral management with monetary incentive, patient education/behavioral management, and attention control. Behavioral observers rated VAC behavior at pretreatment, posttreatment 1-month follow-up, and 1-year follow-up. Knowledge of VAC procedures was also assessed via a questionnaire at pretreatment and posttreatment. Data were analyzed using repeated-measures multivariate analyses of variance. Results indicated that the patients in the education/behavioral, behavioral, and education groups gave significantly more correct answers on our VAC knowledge questionnaires at posttreatment than did patients in the attention control group. Further, patients in the education/behavioral and behavioral groups completed significantly more VAC steps at posttreatment and 1-month follow-up than did patients in the education group and in the attention control group. Differences were not maintained at 1-year follow-up, although more than 50% of the patients were lost to follow-up. Implications of the present findings for behavioral and educational interventions are discussed.     

Sex roles and friendship patterns

The purpose of this study is to examine the relationships among sex, sex role orientation, and friendship. Based on the Bem Sex Role Inventory, 164 participants were categorized as either androgynous (17 males; 29 females), traditional (36 males; 39 females), or undifferentiated (26 males; 17 females) in their sex role orientation. Participants reported the number of close male and female friends, and responded to several questionnaires: interpersonal trust of male and female friends, communal and exchange orientations, affective and activity attributes associated with male and female friends, loneliness, and friendship satisfaction. Results indicate that close friends tended to be same sex, even though females had more close friends overall than did the males. Androgyny was related to characteristics that enhance the development and maintenance of close friendships, such as a communal orientation and positive conceptions of friends, while the undifferentiated orientation was related to less relationship enhancing orientations and a less rewarding interpersonal milieu. The study confirms that sex and sex role orientation are important factors in both quantitative and qualitative aspects of friendship during young adulthood.Portions of this paper were presented at the annual convention of the Southwestern Psychological Association, Houston, Texas, April 13, 1989.

The Future of Neuropsychology in Medical Specialties

Although neuropsychology continues to grow as a valued service in most medical specialties, because of its multiple uses with diverse populations, it is necessary to evaluate the specialty critically in order to ensure continued future success. This article reviews areas in which neuropsychology is most firmly established, potential growth areas, and likely obstacles to success in the future. Suggestions are provided for ways in which neuropsychology can be improved/adapted in clinical, business, research, and training areas. On sabattical at Bebek University, Instanbul, Turkey
