The effect of mild aphasia ( n = 9), as a result of subarachnoid haemorrhage (SAH), was evaluated against one matched (sex, age, and education) control group suffering from SAH of unknown origin without aphasia, and against one matched healthy control group. According to aphasia testing (Reinvang & Engvik, 1980), criteria for a classical diagnosis were not met. Therefore, the patients were characterized as mild aphasics: They generally displayed intact audo-verbal comprehension and repetition abilities, and they demonstrated a fluent, spontaneous speech. However, they showed phonemic and semantic paraphasias, with self-corrections; a few patients displayed alexia and agraphia. Memory performance of these three groups was evaluated by a neuropsychological test battery, designed to tap various components of verbal memory function. From the results it was concluded that: (a) Short-term memory is impaired, as regards the phonological loop and the central executive in working memory, whereas maintenance rehearsal is unaffected, given that the demands on phonological coding is minimized, (b) long-term memory is also generally impaired, whereas long-term learning and forgetting by means of subject-performed tasks proceeds within a normal range. Impairments were hypothesized to reflect less efficient central executive functions of working memory, involving generation of less appropriate semantic codes and phonological representations, (c) mildy aphasic patients are not subjectively aware of their own memory deficits, and (d) aphasia classification by means of standard procedures do not sufficiently characterize the nature of a mildy aphasic patient's memory problems. 相似文献

Abstract. We consider only the relationship of consciousness to physical reality, whether physical reality is interpreted as the brain, artificial intelligence, or the universe as a whole. The difficulties with starting the analysis with physical reality on the one hand and with consciousness on the other are delineated. We consider how one may derive from the other. Concepts of universal or pure consciousness versus local or ego consciousness are explored with the possibility that consciousness may be physically creative. We examine whether artificial intelligence can possess consciousness as an extension of the interrelationship between consciousness and the brain or material reality. 相似文献

Interrater reliability of eight teacher rating scales designed to assess characteristics of attention-deficit hyperactivity disorder was investigated. Coteachers of 46 students completed the rating scales. The students, ages 8–17, were designated as having a Serious Emotional Disturbance. The resulting interrater reliability correlation coefficients ranged from .62 to .87. The percentage of variance shared between raters ranged from a low of 38.4% (the ACTeRS Oppositional factor and the CBCL-TRF Attention Problems factor) to 75.7% (ADHD Rating Scale). The percent of shared variance was higher for younger children. Kappa scores evaluating rater agreement were highest at the two standard deviations above the mean cutoff. The reliability coefficients were consistent with those reported in prior research. 相似文献

It is common in educational, psychological, and social measurement in general, to collect data in the form of graded responses and then to combine adjacent categories. It has been argued that because the division of the continuum into categories is arbitrary, any model used for analyzing graded responses should accommodate such action. Specifically, Jansen and Roskam (1986) enunciate ajoining assumption which specifies that if two categoriesj andk are combined to form categoryh, then the probability of a response inh should equal the sum of the probabilities of responses inj andk. As a result, they question the use of the Rasch model for graded responses which explicitly prohibits the combining of categories after the data are collected except in more or less degenerate cases. However, the Rasch model is derived from requirements of invariance of comparisons of entities with respect to different instruments, which might include different partitions of the continuum, and is consistent with fundamental measurement. Therefore, there is a strong case that the mathematical implication of the Rasch model should be studied further in order to understand how and why it conflicts with the joining assumption. This paper pursues the mathematics of the Rasch model and establishes, through a special case when the sizes of the categories are equal and when the model is expressed in the multiplicative metric, that its probability distribution reflects the precision with which the data are collected, and that if a pair of categories is collapsed after the data are collected, it no longer reflects the original precision. As a consequence, and not because of a qualitative change in the variable, the joining assumption is destroyed when categories are combined. Implications of the choice between a model which satisfies the joining assumption or one which reflects on the precision of the data collection considered are discussed. 相似文献

Despite the wide usage of Conners' 10-item Abbreviated Parent-Teacher Questionnaire (APTQ), normative data for parental ratings on the APTQ are rare. Moreover, its psychometric properties as a stand alone behavioral rating instrument have yet to be examined in detail. Using data from parental ratings for 6,841 children aged 5 to 14 years, this paper reports the psychometric properties of the APTQ and provides normative and prevalence estimates for four age cohorts (5 to 6, 7 to 8, 9 to 11, and 12 to 14 years) by gender. In presenting the findings, the paper highlights key methodological issues endemic to the design of behavioral rating inventories like the APTQ and the analysis of data derived from them. These issues are illustrated and discussed in terms of their implications for the measurement and determination of prevalence estimates of problem behaviors in child psychology and child psychiatry. The need to revise the design, content, and response formats of child behavior rating inventories is stressed. 相似文献

The Adelaide-Conners Parent Rating Scale (APRS), an instrument developed by studying a large, representative group of schoolchildren, was used with a group of psychiatry attenders. Multimethod factor analysis found satisfactory agreement between the factor structures of the clinical and the normative groups. The patterns of scores on the 12 APRS scales were also compared. Two higher-order factors (Conflict with the Environment and Conflict within the Self) were identified in the clinical sample as previously found in the normative group. Comparison of the factor solutions with previous empirical efforts to identify parent-perceived patterns of child behavior disorder showed that the APRS compares well with other instruments and supports the strategy of proceeding from the study of normative populations to the study of clinically defined groups.This work was supported in part by a grant from the Department of Health, Canberra. 相似文献

Researchers have become increasingly concerned about problems of the quality of measurement in applied evaluation settings. Of particular importance is change in both the reliability and the validity of a measure that is used in a novel setting. This problem is illustrated by an attempt to use psychiatric rating scales to assess the behavior of chronic mental patients currently residing in nursing homes. Methods for assessing changes in both reliability and validity are presented, along with suggestions for how to deal with these problems.This research was supported in part by an Extramural Research Grant from the State of Illinois Department of Mental Health and Developmental Disabilities. 相似文献

The Marital Communication Rating Schedule (MCRaS) is presented as an observationally based clinical rating system for assessing verbal behavior in marital communication. Data from 35 response display discussions lasting from 20 to 30 min each, which took place between 11 married couples, were used to examine aspects of the reliability and validity of the instrument. Three raters made independent ratings of 37 MCRaS categories for each husband and wife for each discussion period. Reliability among the raters was shown to be high when calculated within one scale point. Concurrent validity was assessed by comparing MCRaS ratings for four categories with observationally based validation criteria independently coded and measured. Results indicated that for three categories — negative statements, overgeneralizations, and amount of talk — ratings produced results that were similar to those yielded by laborious coding of audiotapes. For one category, opinions requested, a relationship between the ratings and coded data was not found. The validation results were discussed in terms of possible differences in the basis of ratings for the categories subjected to validation. Although further research is needed, it was concluded that MCRaS has many of the desirable qualities needed in a clinically useful, observationally based rating system.This investigation was conducted in connection with the Sociobehavioral Research Project at The University of Michigan when Joyce Borkin and Claude L. Walter were affiliated with the project. 相似文献
