School psychologists have traditionally experienced difficulty in assessing children referred to them for behavior disorders. Given this reported difficulty, a behavioral assessment model is proposed which specifies three types of assessment information: direct observations, rating scale data, and interview data. Characteristics of these three types of assessment information are discussed, along with recommendations for their use. Two psychological models are suggested to guide school psychologists through the assessment process. Bergan's behavioral consultation model is recommended for securing valid and reliable interview and observational data, and Campbell and Fiske's multitrait-multimethod model is proposed as a means of logically integrating behavioral assessment information. The notion of convergence or agreement between dissimilar assessment methods is discussed. 相似文献

Three experiments investigated the effects of reinforcement magnitude on conditioned key pecking in pigeons. Experiment 1, which included between-groups and within-subject designs, yielded significant effects of unconditioned stimulus (US) magnitude on the within-conditioned stimulus (CS) distribution of key pecks and on choice behavior, but no effect on the overall rate of key pecking. Experiment 2 employed a larger US-magnitude difference in a within-subject design. This manipulation resulted in differential rates of key pecking as well as a significant choice effect and differential within-CS key-peck distributions. A second-order conditioning procedure was used in Experiment 3, in which diffuse, visual stimuli (S1's) served as Pavlovian reinforcers for two key-light S2's. The S1 previously paired with a large US was more effective in conditioning second-order key-peck behavior to an S2 than was the S1 paired with a small US. The results of these experiments demonstrate that the associative effects of US magnitude can be expressed in the strength of CS-directed motor responding. The distinctive within-CS key-peck distributions in first-order conditioning suggests an interaction between CS- and US-directed responses. 相似文献

The person-by-situation interaction model of anxiety was tested in the reallife setting of an academic examination. Twenty-eight male and 79 female university students served as subjects. State anxiety (A-State) was assessed just prior to the examination (Trial 2) and approximately 1 week before (Trial 1) and after (Trial 3) the examination. Five facets of trait anxiety (A-Trait) were measured in a nonstressful situation 1 week prior to the examination. The subject's cognitive appraisal of the various situations was assessed by a self-report index of the type and degree of threat involved in the situation just experienced. As predicted, a significant A-Trait-by-situation interaction in eliciting A-State was observed for social evaluation A-Trait. There were no interactions for the other, noncongruent facets of trait anxiety. The results also indicated that individuals' perception of situations may be the most important factor affecting reactions to stressful situations. In general, the results were interpreted as providing support for the multidimensionality of A-Trait and further validation of the interaction model of anxiety. 相似文献

Lexical decision for open- and closed-class words: failure to replicate differential frequency sensitivity 总被引:1,自引:0,他引:1
Bradley and her colleagues (D. C. Bradley, Computational distinctions of vocabulary type, unpublished Ph.D. thesis, Massachusetts Institute of Technology, 1978D. C. Bradley, M. E. Garrett, &; E. B. Zurif, in D. Caplan (Ed.), Biological studies of mental processes, Cambridge, MA: MIT Press, 1980) have reported a marked difference in frequency sensitivity between open- and closed-class words on a lexical decision task. This effect was obtained with normal subjects, but not with Broca's aphasics. Their results have already influenced experimental and theoretical investigations of syntactic processing. However, in three lexical decision experiments with normal subjects, modeled on those of Bradley et al., we failed to find such a theoretically interesting difference between the two classes. Instead, both classes showed similar reaction time frequency sensitivity for word frequencies less than approximately 316/million (H. Kucera &; W. N. Francis, Computational analysis of present-day English, Providence, RI: Brown Univ. Press, 1967, count); above 399/million, the closed class had an almost-flat function of reaction time versus the logarithm of the frequency, while the open class may have had too few members for meaningful assessment. Because reaction time may be a nonlinear function of log frequency, and because there is relatively little overlap between the frequency ranges of the two classes, comparisons of the members of the two classes which might straddle the function's inflection point must be made with extreme caution. 相似文献

Children and adolescents as producers of their own development 总被引:1,自引:0,他引:1
Richard M. Lerner 《Developmental Review》1982,2(4):342-370
Interest in the historically changing contexts of human life has been associated with the elaboration of a life-span view of human development. This view holds that all levels of the context, including the biological, psychological, and sociocultural, change in reciprocal relation to one another. As a consequence of being embedded in a context which they both influence and are influenced by, children and adolescents may promote their own development. One way this occurs is that as a consequence of their characteristics of physical and behavioral individuality people promote differential reactions in their socializing others (e.g., parents, teachers, or peers); these reactions feed back affecting further development. My colleagues and I have conducted research that describes such child and adolescent contributions to development. We have focused on characteristics of physical individuality, such as body type and physical attractiveness, and on characteristics of behavioral individuality, such as behavioral style or temperament. Findings from these studies are conceptualized in terms of a person-context “goodness-of-fit” model. Adaptive development is associated with congruence, or fit, between a person's attributes of individuality and the demands of his or her setting. Implications of this research for illustrating the use of the life-span perspective, and for theory in and practice of intervention, are discussed. 相似文献

An analysis of the concurrent incidence of aphasia and spatial disorder in 270 patients with unilateral brain damage suggests that the two functions are statistically independent. These data can also be used to estimate the distribution of left, right, and bilateral representation of linguistic and spatial functions in the population. In right-handers, sex affects the pattern of cerebral asymmetries, while the familial history of sinistrality has a stronger effect on the pattern of cerebral asymmetries in left-handers. These findings suggest that complementary specialization exists only as a statistical norm: It is suggested that differences in complementary and noncomplementary specialization may underlie individual differences in cognitive skills. 相似文献

Most right-handed crossed aphasics are not apractic. They usually have agraphia characterized by misspellings but retain the ability to write well-formed graphemes. We describe a right-handed patient with a right parietal lesion who was aphasic and not apractic. He was unable to write any formed graphemes despite a relatively preserved ability to spell aloud. We postulate that praxis and writing are dissociated in this patient because the motor engrams for praxis were located in his left hemisphere and the engrams for writing were in his right hemisphere. In addition, he comprehended commands for limb motor activities (praxis) far better than he comprehended other speech. This suggests that in this patient the areas used to comprehend limb motor commands may be anatomically distinct from areas important in comprehending other aspects of speech. 相似文献

Recently, perceptual evaluation of the nonstuttered speech of stutterers has received renewed research interest. To summarize, the majority of research on this subject reported the nonstuttered speech of adult stutterers was perceptually identifiable from that produced by normal speaking individuals. A continuation of this line of research would be to determine if the nonstuttered speech of children would be equally recognizable. The results of this investigation would indicate this is not the case. The implications of the sophisticated judge's inability to identify stuttering children based on nonstuttered speech are discussed. 相似文献

Educable mentally retarded (EMR) and nonretarded adults free recalled lists of (a) words, (b) minitasks performed by the subjects (SPTs), (c) minitasks performed by the experimenter (EPTs), or (d) task instructions. The EMR subjects were significantly inferior to the nonretarded subjects in the immediate recall of words, EPTs and instructions, but not in the immediate recall of SPTs. This proficiency of the EMR subjects in SPT recall was attributed to the nonstrategic nature of this test. The EMR subjects were, however, inferior to the nonretarded subjects in a final free recall (recall of all lists) of all four types of item. 相似文献
