The purpose of this study was to examine the relative effectiveness of sex-balanced and sex-restrictive raw score interest scales in discriminating among vocational preference groups. Analyses were conducted separately for 502 males in six vocational preference groups and 878 females in five vocational preference groups. The degree and nature of the discrimination among groups were highly similar for the two types of scales for both males and females. Centour scores derived from sex-balanced and sex-restrictive raw scores resulted in essentially the same percentages of correct classifications of group membership. The results of this study suggest that the large sex differences traditionally found in interest inventory items may not be a necessary concomitant of validity. Hence, interest inventory reports that reflect these differences may unnecessarily restrict the career suggestions they provide to women and men.  相似文献

Two experiments were reported investigating the possibility that normal children (6- to 7-years old) and retarded children (9- to 10-years old) equated for immediate memory performance may not use effective strategies to eliminate interference from irrelevant information in memory. In both experiments a directed forgetting paradigm was used in which the children were presented with two sets of four pictures, and recalled only one set on each trial. On some trials, there was a cue to forget the first four and to remember only the last four pictures. In the first experiment both groups adopted a passive-active strategy in which the to-be-remembered items were processed actively only after a forget cue. Experiment 2 replicated this pattern of results. The use of sophisticated directed forgetting strategies seemed to be beyond the immediate abilities of these children. Two possible interpretations of the passive-active strategy were offered: (a) The strategy was an attempt to cope with the presence of occasionally irrelevant information and (b) The strategy was an attempt to cope with memory overload.  相似文献

Different varieties of deviant spoken language segments (phonemic, morphemic, verbal, and syntagmic paraphasias and télescopages, neologisms) and different forms of deviant spoken language behaviors (thematic production, dyssyntaxia, glossolalia, and glossomania) are defined and exemplified. Their production is shown to be rule-governed at phonetic and phonological levels; it is shown to be rule-governed or rule-deviant at morphological and/or syntactic levels. Their qualitative and quantitative attributes in normal discourse in the jargonaphasias and in schizophasia are compared. It is underlined that the latter is a behavior episodically observed in only a small proportion of subjects considered to be schizophrenics. Awareness of, and deliberateness in, deviant language production are discussed. A distinction is made between deviations testifying to diminished ability, which betray the speaker's intention, and deviations testifying to singular but rigorous use of ability, which are adapted to the speaker's intentions. The former are contended to be common in the jargonaphasias and occasional in standard discourse and schizophasia, the latter to be characteristic of schizophasia and of various forms of “literary” language, but incompatible with aphasia. In lapidary terms, this implies that ordinary speakers think and talk standard, that (most) jargonaphasic speakers think standard but talk deviant, that schizophasic speakers think quaint and talk accordingly. It is further suggested that the differential diagnosis of jargonaphasia and schizophasia, when made on the sole basis of tape recorded samples of discursive language, resorts mainly to quantitative appraisal of different types of deviant segments on one hand, and, on the other, to the listener's interpretations of the speaker's mode of ideation. Within the realm of pathological language production, nearly exclusive and important production of phonemic transformations is said to be characteristic of conduction aphasia; combined production of numerous phonemic and verbal transformations, and of neologisms, is said to be characteristic of Wernicke's aphasia proper; nearly exclusive and important production of verbal transformations is said to be possible in so-called transcortical sensory aphasia; and predominant production of morphemic transformations and of glossomaniac utterances is said to be characteristic of schizophasia. Linguistic definitions of the “disturbances” behind schizophasic utterances are reviewed. Indications are given concerning the evolution of language behavior in jargonaphasia and schizophasia.  相似文献

This study investigates the importance of two “person” variables, reflection impulsivity and divergent thinking, and one “situation” variable, the classroom climate of first-grade classrooms, for the classroom adaptation of first-graders. Three types of classrooms differing in classroom climate were selected: open, intermediate, and traditional. Subjects were the children (n = 189) in these classrooms. Classroom adaptation variables included self concept, school attendance, and teacher ratings of classroom behavior, overall academic rank, and personal preference. Both main effect and interactional relationships between “person” and “situation” variables and classroom adaptation were hypothesized. Classroom environment was found to affect degree of classroom disturbance manifested by the children with students in open classrooms exhibiting most and students in the intermediate classrooms exhibiting least. Boys in the open classrooms had higher achievement anxiety and lower teacher preference ratings than boys in traditional or intermediate classrooms. Reflective children obtained higher ratings as self-reliant learners and, for boys, reflection was related to low classroom disturbance and high achievement anxiety. Interactional relationships between classroom environment and reflection-impulsivity were also found for boys. Divergent thinking was not related to classroom adjustment for boys. Girls high in divergent thinking were higher in school involvement and achievement anxiety and more preferred by teachers.  相似文献

In order to examine the timing control of laryngeal and supralaryngeal articulatory adjustments in apraxia of speech, voice onset time (VOT) data for stop consonants in monosyllables /de/, /te/, /ge/ and /ke/ were obtained from four apraxic subjects and compared with those of fluent aphasic and normal (both young and aged) speakers (Experiment 1). The results indicated that the VOT distribution patterns of the apraxic patients differed markedly from those of the other speakers. A second experiment was conducted to determine whether the VOT distribution patterns of these four apraxic patients and of two normal controls would change with a lapse of time (Experiment 2). The results of the second experiment demonstrated marked changes in the VOT distribution patterns over time in half of the apraxic patients examined, but essentially no change in the normal controls.  相似文献

This paper reports on the psycholinguistic investigation of a surface dyslexic aphasic patient's abilities to handle written material. The analysis of paralexic errors produced in reading aloud single words and nonwords classically suggested that the patient was using an analytical strategy parsing the letter string stimulus, from left to right, into graphemes, and assigning phonemic values to graphemes. The patient's results were found to be sensitive to irregularities in correspondence between graphemes and phonemes not only in reading aloud but in lexical decisions, writing on dictation, rhyming, and written-word comprehension. Moreover, the patient's linguistic behavior brought out the reverse pattern observed in deep-dyslexic performances within word/nonword and content/function word dimensions. It was found that some semantic information about written words could be retrieved from both phonological and nonphonological processes presumably operating concurrently and both providing converging or conflicting pieces of meaning to the understanding of written words. Some considerations derived from the observation of this pathological reading behavior are discussed, contributing to a psycholinguistic model of normal reading.  相似文献

A number of methodological features were incorporated in a paradigm designed to maximize the likelihood of finding reliable event-related potential (ERP) signs of functional specializations between and within the cerebral hemispheres. Every subject was more accurate in identifying words presented to the right than to the left visual field. The morphology of the ERPs elicited by these words varied considerably as a function of electrode position both within and between the hemispheres. Amplitude asymmetries of ERP components recorded from occipital regions of the two hemispheres varied systematically with the position of the word in the visual field. On the other hand, ERPs from more anterior (temporal and frontal) regions displayed large asymmetries which were in the same direction regardless of the visual field of word presentation. The most prominent such asymmetry was in the negativity in the region 300–500 msec (N410) which was larger in the left than the right hemisphere in every subject. These results demonstrate that in this paradigm which demands specialized language processing ERPs are sensitive to aspects of cerebral organization both within and between the two hemispheres.  相似文献

The hypothesis that perceptual development proceeds from less to greater dimensional separability was tested by giving a speeded classification task to first and fouth graders. In Experiment 1, children sorted line drawings of a cartoon figure into two piles according to his eyes (open or closed) or his mouth (smiling or frowning). First graders exhibited the pattern characteristic of integral dimensions: An interference effect was found when dimensions were combined orthogonally and a facilitation effect when dimensions were correlated, relative to a condition in which only one dimension varied. Fourth graders exhibited an optional separable pattern: There was facilitation in the correlated condition but no interference in the orthogonal condition. These results support the hypothesis that development proceeds toward greater flexibility of attention rather than simply toward increasing separability. A flexible field hypothesis of visual attention was suggested to explain how older children can exercise such optional separability. This hypothesis correctly predicted the asymmetrical relation between dimensions found in Experiments 2 and 3: For both first and fourth graders, the eyes of a cartoon figure (open or closed) and his location (right or left) were nonseparable when the eyes were relevant and separable (or optional separable) when location was relevant.  相似文献

This paper describes an experiment concerned with the operation of discriminatory processes subsequent to an individual's overt choice response and how these may be affected by extrinsic stimulus information. The experiment used subhuman primates and was conducted within the simultaneous two-choice visual discrimination paradigm. The major results of the experiment indicated that: (1) learning performance may be significantly interfered with by irrelevant postresponse stimulus information, and (2) this interference is primarily associated with the presentation of irrelevant information subsequent to nonreinforced choice responses. The results are discussed in terms of the relation between the occurrence of reinforcement and the operation of memory storage processes.  相似文献

This review describes methodological improvements of the 133Xe-inhalation technique for measurement of regional cerebral blood flow (rCBF) comprising correction routines both for scattered radiation from air passages and for remaining activity from previous measurements, as well as a new index of curve fit exactness. Measurements in normals are described showing new characteristics of the resting flow pattern and localized flow changes during activation with a variety of mental tasks. Our clinical applications in psychiatry are reviewed demonstrating the ability of the rCBF technique for differential diagnosis of dementia, for the evaluation of treatment by drugs, ECT, or psychosurgery, as well as for following, cases of toxic influence. The paper finally discusses the potentials as well as the limitations and artifacts of the technique.  相似文献
