When a single abrupt onset appears in a multielement display, it captures attention. When multiple onset elements occur, they have conditional priority over no-onset elements such that a limited number of onsets can be serviced with high priority in visual search (Yantis & Johnson, 1990). We report three experiments in which we assess two possible mechanisms for attentional prioritization: a priority queue into which a fixed number of high-priority elements are placed for early servicing during search, and a mechanism that temporarily tags all high-priority elements for early servicing or more frequent sampling. We manipulated the visual quality or inter-letter confusability of the stimuli to prolong encoding and/or comparison operations; this manipulation led to a decrease in the estimated number of elements serviced with high priority. We conclude that a mechanism incorporating temporally decaying priority tags is implicated in servicing multiple abrupt onsets in visual search. 相似文献

The Reasons for Living Inventory: psychometric properties 总被引:1,自引:0,他引:1
The test-retest reliability, internal consistency reliability, normative, and item analysis data of the Reasons for Living Inventory were investigated in a sample of 116 college students. The inventory has six subscales, each of which assesses a category of adaptive beliefs and expectations considered reasons for not committing suicide. The inventory was administered twice, with a 3-week interval between testings. Test-retest coefficients for the men, women, and total sample were moderate to high. The alpha coefficients and item-total correlations for the subscales and the total inventory provided strong support for internal consistency. 26 items were consistently endorsed by 30% or more of our total sample as "extremely important," while only four were suggested as "not at all important" reasons for not committing suicide. 相似文献

This study examined the effects of personal religious orientation, religious denomination, and gender on attitudes toward women and their work roles using a sample of 263 single undergraduate university students. Subjects with a high intrinsic religious orientation put significantly more emphasis on family than career in their anticipated general lifestyle relative to those with a low intrinsic religious orientation. Subjects with a high intrinsic religious orientation were also more likely to anticipate the female spouse spending less time in a profession during the children's early years. Males showed more traditional attitudes toward women than females, but there were no gender effects on measures of preferred general lifestyle, preferred child-care distribution, or preferred career involvement for the wife. Subjects belonging to mainline and conservative denomination did not differ significantly in their attitudes toward women or their work roles. 相似文献

This pilot study was conducted to determine if clinically-oriented test items are judged to be more offensive than job-related test items. Clinical tests typically ask more personal questions while employment tests usually ask job-relevant questions. A random selection of items from three employment tests was analyzed. Two of the tests evolved from clinical-personality tests, while the third test was designed specifically for employment settings. The results suggest that if companies are interested in using employment tests that are perceived as being job-relevant, inoffensive, and non-invasive, then they should consider selecting tests that include job-relevant items as opposed to tests that are derivatives of clinical assessment instruments. 相似文献

Holland uses a hexagon to model relationships among his six types of vocational interests. This paper provides empirical evidence regarding the nature of the interest dimensions underlying the hexagon. Two studies are reported. Study 1 examines the extent to which two theory-based dimensions—data/ideas and things/people—fit 27 sets of intercorrelations for Holland's types. Three of the data sets involve the mean scores of career groups (total of 228 groups and 35,060 individuals); 24 involve the scores for individuals (total of 11,275). Study 2 explores the heuristic value of the data/ideas and things/people dimensions by determining whether they contribute to the understanding of why interest inventories work. Two data sets covering a total of 563 occupations are used to calculate correlations between the vocational interests of persons and the tasks which characterize the persons' occupations. Each occupation's principal work tasks are determined from job analysis data obtained from the U.S. Department of Labor. Study 1 results provide substantial support for the theory-based dimensions. Study 2 results suggest that interest inventories “work” primarily because they tap activity preferences which parallel work tasks. Counseling and research applications of the data/ideas and things/people dimensions are suggested and implications for interest assessment are noted. 相似文献

The speed and accuracy of judgements made by pre-school children on the Kansas Reflection-Impulsivity Scale for Pre-schoolers (KRISP - Wright 1971, 1973) and on a two-choice length discrimination task were investigated. If subjects were relatively accurate on the KRISP then correct responses tended to be faster than errors while if subjects were relatively inaccurate errors were the faster. It is inferred that accurate subjects respond asymptotically in terms of a speed-accuracy tradeoff while inaccurate subjects set a less demanding criterion. Accurate subjects showed a tendency to increase inspection time as a function of item difficulty. This relation did not hold for inaccurate subjects.However, groups classified by means of the KRISP did not differ in either the speed of correct responses or accuracy of line length discriminations. For all groups judgement times were significantly related to stimulus differences and to stimulus ratios. There was no evidence that so-called impulsive children engage in less efficient and less detailed processing than other children.It is argued, contrary to the view of Kagan and his co-workers (e.g. Kakan 1966), that speed and accuracy of responding may not reflect a stable trait dimension. Rather children appear to be able to change their strategies according to the particular demands, implicit or explicit, of the task. 相似文献

To minimize the verbal content of the attitude measurement situation with Papua New Guinea students, a set of pictorial items was selected for use in the place of verbal items. Initially, 150 pictures related to concepts in the Wilson-Patterson Attitude Inventory (WPAI) were described by a group of 50 students. Seventy of these items, those which were described in a consistent way, were presented to 227 students along with a Papua New Guinea version of the WPAI. A final set of 25 pictures was selected on the basis of their discriminative power, internal consistency, and their content validity. Reliability and validity measures and the rotated factor structure of the 25 item pictorial scale were consistent with the WPAI. 相似文献

Two strategies used to test prerequisite relationships among intellectual skills were employed to examine the sequence of three types of subtraction tasks. A psychometric validation strategy yielded results similar to an instructional validation strategy. This finding provides support for the use of the more efficient psychometric approach for validating large numbers of learning hierarchies in relatively short periods of time. 相似文献
