A study is reported which focused on the problem-solving strategies employed by expert electronics engineers pursuing a real-world task: integrated-circuit design. Verbal protocol data were analysed so as to reveal aspects of the organisation and sequencing of ongoing design activity. These analyses indicated that the designers were implementing a highly systematic solution-development strategy which deviated only a small degree from a normatively optimal top-down and breadth-first method. Although some of the observed deviation could be described as opportunistic in nature, much of it reflected the rapid depth-first exploration of tentative solution ideas. We argue that switches from a predominantly breadth-first mode of problem solving to depth-first or opportunistic modes may be an important aspect of the expert's strategic knowledge about how to conduct the design process effectively when faced with difficulties, uncertainties, and design impasses. 相似文献

This study aimed to better understand the psychological mechanisms, referred to in the job demands–resources model as the energetic and motivational processes, that can explain relationships between job demands (role overload and ambiguity), job resources (job control and social support), and burnout (emotional exhaustion, depersonalization, and personal accomplishment). Drawing on self-determination theory, we examined whether psychological resources (perceived autonomy, competence, and relatedness) act as specific mediators between particular job demands and burnout as well as between job resources and burnout. Participants were 356 school board employees. Results of the structural equation analyses provide support for our hypothesized model, which proposes that certain job demands and resources are involved in both the energetic and motivational processes—given their relationships with psychological resources—and that they distinctively predict burnout components. Implications for burnout research and management practices are discussed. 相似文献

The aim of the present study is to examine to what extent general and situation-specific work environment instruments capture the salient work characteristics in a knowledge-intensive context. We conducted qualitative open-ended interviews with 30 employees (24 men and six women) from a Norwegian university department. The information from the interviews was content-analysed and coded on the scales of five work environment instruments; two general instruments (the General Nordic Questionnaire for Psychological and Social Factors at Work [QPSNordic] and the Job Diagnostic Survey [JDS]) and three situation-specific instruments (Assessing the climate for creativity [KEYS], Situational Outlook Questionnaire [SOQ], and the Organizational Climate Measure [OCM]). The results showed that situation-specific work environment instruments covered significantly more statements about the work environment than the general instruments. More statements could be categorized on the organization and individual levels, compared to group and leadership levels. The situation-specific instruments covered more statements than general instruments at the organization level. These statements were mainly related to the organizational context, social and relational characteristics, and encouragement of creativity and organizational impediments to creativity. The findings support the value of situation-specific instruments for assessing the work environment in knowledge-intensive organizations. 相似文献

Diary studies are scarce within the field of qualitative psychotherapy research. In this article arguments for and against the employment of solicited diary studies in qualitative psychotherapy research are investigated. The strengths of diary studies are presented along with arguments concerning their pertinence to the field. Limitations and potential critiques regarding the use of diaries are also addressed. 相似文献

The more replicated findings about gender difference in cognitive performance suggest female superiority on visuomotor speed and language ability and male superiority on mechanical and visuospatial tasks. Generally, group strengths found in the early school years become more established at adolescence and remain stable through adulthood. The current study tested whether the patterns established in the early years remained among 30 adult subjects. We also utilized a series of exploratory analyses to determine if observed gender differences were impacted by the covariance present between all cognitive tests. Results suggest that although the patterns established in the early years remain stable through time for males, the established patterns for females are altered with age. Our findings are compelling in supporting a male advantage on visuospatial tasks among older adults. These findings are discussed in terms of common variance between test instruments as a possible source of difference. Our finding that the gender effect tended to increase when common variance was controlled argues that this methodology may enhance the ability to detect domain specific effects. 相似文献

The debate continues with regard to whether degradation of semantic knowledge or deficits in information processing lead to impaired memory performance in patients with Alzheimer's disease (AD). This study examined the effects of semantic content and working memory demands on the recall and recognition abilities of patients with mild AD. Nineteen patients with probable AD and 19 demographically matched normal control participants were asked to remember prose passages that varied in semantic content (high, medium, and low level of idea importance) and working memory demands (narrative and expository passages). Compared to the controls, patients with mild AD lost the ability to recall prose in a manner consistent with the semantic structure of the passages as the demands on working memory increased. Furthermore, as the demands on working memory increased, patients recognized information in a manner that suggested their initial processing was of isolated details rather than by semantic structure. This study provides support for the hypothesis that information processing deficits contribute to impaired semantic processing in patients with mild AD. 相似文献

Random-array letter cancellation tasks are commonly used in the clinical assessment of visuospatial function. How stimulus properties and aging affect cancellation performance is not well understood. This study evaluated the effects of stimulus factors and age on 3 measures of cancellation performance. Thirty younger and 30 older adults each completed 12 cancellation forms that varied in paper size, stimulus density, and target-to-distractor (T/D) ratio. Interactions between stimulus factors were identified for a calculated composite measure of speed and accuracy (effectiveness), a standardized measure of the time required for completion of forms, and a standardized measure of the number of omission errors. The results showed complex interactions between stimulus factors that were different for each dependent variable. These interactions were generally similar for both age groups. The findings indicate that both stimulus properties and dependent variables must be carefully considered in the design and interpretation of cancellation paradigms. 相似文献

Why are people trustworthy? I argue for two theses. First, we cannot explain many socially important forms of trustworthiness solely in terms of the instrumentally rational seeking of one’s interests, in response to external sanctions or rewards. A richer psychology is required. So, second, possession of moral character is a plausible explanation of some socially important instances when people are trustworthy. I defend this conclusion against the influential account of trust as ‘encapsulated interest’, given by Russell Hardin, on which most trustworthiness is explained by the interest of continuing relationship. 相似文献
