The expectation of cooperative future interaction (ECFI) encouraged especially high joint benefit (the total of the two bargainers' individual outcomes) when resistance to yielding was high, but especially low joint benefit when resistance to yielding was low. Process data suggest that this finding can be explained as follows: When resistance to yielding is high, ECFI encourages problem solving and reduced contentious behavior; when resistance to yielding is low, ECFI encourages a collapse of aspirations. The results support Filley's (1975) dualconcern model and cast doubt on Deutsch's (1973) blanket assertion that a cooperative process leads to constructive conflict resolution. 相似文献

Children referred with specific reading dysfunction were subtyped as accuracy disabled or rate disabled according to criteria developed from an information processing model of reading skill. Multiple measures of oral and written language development were compared for two subtyped samples matched on age, sex, and IQ. The two samples were comparable in reading fluency, reading comprehension, word knowledge, and word retrieval functions. Accuracy disabled readers demonstrated inferior decoding and spelling skills. The accuracy disabled sample proved deficient in their understanding of oral language structure and in their ability to associate unfamiliar pseudowords and novel symbols in a task designed to simulate some of the learning involved in initial reading acquisition. It was suggested that these two samples of disabled readers may be best described with respect to their relative standing along a theoretical continuum of normal reading development. 相似文献

Students representing the top 0.03% of their age group in intellectual ability, who were identified by the Study of Mathematically Precocious Youth (Benbow & Stanley, 1980), were tested along with their parents using a battery of specifically designed cognitive tests. These highly intelligent children had less intelligent, but yet quite bright parents. Vernon's (1961) model of intelligence best fits our results. His following two factors explained most of the variance in the performance of the students and parents: verbal-educational and practical-spatial-mechanical. Moreover, there was potential evidence for a general factor. Among the children, who were mostly past puberty, age related to development of verbal abilities, but not spatial or mechanical abilities. Sex differences favoring the males were found on the spatial ability and mechanical comprehension tests. 相似文献

This study was designed to investigate the differences between stutterers and normal speakers in phonatory and articulatory timing during the initiation of fluent utterances of monosyllabic words. Electromyographic recordings of four articulatory muscles and recordings of glottal vibrations were made of repetitive utterances of a series of monosyllabic words by 15 stutterers and 17 nonstutterers. These data were analyzed in terms of average interval times between voice onset and onset of EMG activity and between onset of EMG activity in each articulator and in terms of the intrasubject variability of these durational measures. Results showed that there were no significant differences between stutterers and nonstutterers in average interval times and that stutterers, in general, were significantly more variable in their speech onset timing. Findings are discussed in terms of recent hypotheses concerning the role of timing disturbances as the main source of speech disruption in stutterers. 相似文献

Three experiments using beginning Dutch readers (7 and 8 years of age) as subjects provide evidence that visually recognizing the unique graphemic structure of words is an important component in word identification, even at rather early stages in learning to read. Only a moderate amount of practice in reading strings of letters was necessary for young children to read the regular spelling faster than an altered spelling that preserved the word sound. In normal beginners this effect appeared regardless of their ability to identify the words the first time; in learning-disabled children, matched in overall reading speed, learning about the graphemic compositions of words seems to proceed at a much slower rate. The results are discussed with regard to the importance of building accurate graphemic entries in the mental lexicon for acquiring fluency in reading. 相似文献

In a recent article in this journal, Hellige (Brain and Cognition, 2, 199-203, 1983) presented a critique of the chimeric-face technique that was used by us to validate a hand preference questionnaire. Data were presented by Hellige to show that the left visual field (LVF) bias that occurs on this task is due primarily to differences in detail in the features of the two faces and not because of right hemisphere dominance for face perception. In our rebuttal, we acknowledge that the two faces are not mirror-image duplicates of each other, but contend that this fact does not explain why differences between left-handers and right-handers have been observed on this task. Further data on the role of handedness as well as other variables impacting on this task are presented. A possible explanation is also offered for the rather small extent of LVF bias that Hellige obtained when he used corrected (i.e., true mirror-image) versions of Jaynes' chimeric faces. 相似文献

A study was designed to tap children's perceptions of the divorce situation as opposed to adults' perceptions of the child's response to the parental divorce. Subjects were 75 boys and 75 girls from mother- and father-headed families. Using an individual structured interview procedure children were encouraged to reconstruct both positive and negative dimensions of their interactions with the custodial parent. Through factor analyses of the contents of interviews four negative and two positive factors involving 20 specific items were identified in the children's perceptual data. Subsequently, chi-square analyses were done to compare differences in girls' and boys' perceptions between and across father- and mother-headed families. Results are discussed in terms of their relationship with the existing literature and their clinical and educational relevance to children, single parents and professionals. 相似文献

Current practice in structural modeling of observed continuous random variables is limited to representation systems for first and second moments (e.g., means and covariances), and to distribution theory based on multivariate normality. In psychometrics the multinormality assumption is often incorrect, so that statistical tests on parameters, or model goodness of fit, will frequently be incorrect as well. It is shown that higher order product moments yield important structural information when the distribution of variables is arbitrary. Structural representations are developed for generalizations of the Bentler-Weeks, Jöreskog-Keesling-Wiley, and factor analytic models. Some asymptotically distribution-free efficient estimators for such arbitrary structural models are developed. Limited information estimators are obtained as well. The special case of elliptical distributions that allow nonzero but equal kurtoses for variables is discussed in some detail. The argument is made that multivariate normal theory for covariance structure models should be abandoned in favor of elliptical theory, which is only slightly more difficult to apply in practice but specializes to the traditional case when normality holds. Many open research areas are described. 相似文献

The study evaluates a test of occupational information administered to a national sample of 5000 young men, aged 14–24 in 1966, as part of the National Longitudinal Surveys of employment behavior. The predictive validity of the test score is assessed by reference to multiple regression analyses which confirm the significance of the score as an independent predictor of subsequent hourly earnings and occupational status. Correlation and factor analyses are used to examine the quality of the measurement instrument. All in all, the instrument is judged to exhibit desirable characteristics in terms of internal consistency reliability, discriminatory power, and level of difficulty. The test's reliability compares favorably with a commercially produced test designed to be used in counseling as a measure of occupational knowledge. With the possible modification of deleting a section relating to knowledge of earnings differentials, the test is commended to those involved in assessing and counseling the occupational choice process. 相似文献

Expectancy theory predictions were tested using a sample of engineers who had been rated on dimensions of work motivation or effort (in contrast to performance) using the behaviorally based rating scales designed by Landy and Guion (1970). It was found that the expectancy model was only weakly upheld for an older (41 or older) age subgroup, while few relationships were observed for a younger (below 41) age group. Also, the motivational behavior scales did not show any enhanced predictability when compared to a more global rating of job performance. 相似文献
