The relationship during a simple reaction time task between heart rate and four measures of task irrelevant somatic activity was evaluated in four age groups of children, i.e., 4-, 5-, 8-, and 10-year-olds and young adults, in order to evaluate further a hypothesized coupling of cardiac and somatic activity. At all age levels, phasic decreases in both heart rate and somatic activity coincident with performance were found with the magnitude of the effect increasing with age only on three somatic measures. However, tonic levels of both heart rate and somatic activity decreased with age. Performance on the reaction task was found to be inversely related to the age-related phasic somatic effects as well as age-related tonic heart rate and somatic activity. 相似文献

This study investigated reasoning with abstract conditional sentences as a function of age. Subjects from third-grade to eleventh-grade were required to evaluate the conclusion of several conditional arguments. The results confirmed the previously established finding that performance improves with age, particularly between 11 and 15 years. This finding could be interpreted to indicate that individuals become more logical as they get older. However, another possible interpretation is that the meaning of a conditional sentence like pthenq for naive Ss may not always be given by the truth function pq true, false, true, and true. Further analysis suggested that at 9 years individuals treat the connective in the sentence, ifpthenq, as if it were either a conjunctive or a biconditional, that the conjunctive meaning disappears with increasing age and after 13 years is gradually superceded by the conditional. 相似文献

The stimulus-familiarization-effect (SFE) paradigm, a reaction-time (RT) task based on a response to novelty procedure, was modified to assess response for novelty, i.e., a response-reinforcement sequence. Ninetysix kindergarten children were familiarized on one of two colored lights. Then Ss were confronted with a simple position discrimination task in which they could choose between two response buttons which produced either the previously familiarized light or a new (i.e., novel) light. Results showed that the choice response for the novel stimulus (NS) was facilitated by three variables: number of exposures to and duration per exposure of the familiar stimulus (FS), and degree of change provided by the NS relative to the FS. The parallel between the effective variables of this study and those which produce the SFE was noted, implicating an attention interpretation of the function of novelty as a reinforcer. The potential implications of attention for reinforcement theory and learning in general are discussed. 相似文献

Pascual-Leone's neo-Piagetian theory of development was used to predict the pre- and postinstruction distributions of scores on a subject-controlled digit placement task as a function of three parameters: (1) the mental strategy which subjects attempted to apply, (2) the demand which attempting to apply this strategy placed on their mental capacity, and (3) the maximum mental capacity which they were capable of mobilizing. The predicted and obtained distributions corresponded quite closely for each kind of strategy at each age level sampled (6, 8, and 10). The discussion focused on the methodological and analytic requirements which must be met if the same approach is to be applied to making successful predictions in more naturalistic paradigms. 相似文献

Token test performance by dyslexic adolescents 总被引:2,自引:0,他引:2
Catherine C. Whitehouse 《Brain and language》1983,18(2):224-235
An abbreviated form of the Token Test was administered to 42 normal readers and 42 dyslexic adolescent males. The greatest divergence between the two groups was seen on Part V where syntactic complexity varies. An error analysis also supported the hypothesis that some, but not all, dyslexics have an impaired ability to process syntactic information. The Token Test, particularly Part V, would be a useful aid in the evaluation of dyslexic individuals. 相似文献

The roles of attention in reaction time and in the relationships among reaction time, intelligence, and achievement were analyzed. The subjects were 105 seventh-grade children. The results were generally consistent with most studies involving the Hick paradigm: both mean reaction time and the standard deviation of reaction time correlated with the intelligence and achievement measures used. Reaction time measures were correlated with attention and perceptual speed as well as with general intelligence, or g. Implications of these results for current theories linking reaction time and intelligence are discussed. 相似文献

Two lines of research—one in psycholinguistics and one in linguistics—are combined to deal with a long-standing problem in both fields: why the “performance structures” of sentences (structures based on experimental data, such as pausing and parsing values) are not fully accountable for by linguistic theories of phrase structure. Two psycholinguistic algorithms that have been used to predict these structures are described and their limitations are examined. A third algorithm, based on the prosodic structures of sentences is then proposed and shown to be a far better predictor of performance structures. It is argued that the experimental data reflect aspects of the linguistic cognitive capacity, and that, in turn, linguistic theory can offer an illuminating account of the data. The prosodic model is shown to have a wider domain of application than temporal organization per se, accounting for parsing judgments as well as pausing performance, and reflecting aspects of syntactic and semantic structure as well as purely prosodic structure. Finally, the algorithm is discussed in light of language processing. 相似文献

This study sought: (1) to compare the occupational stress profiles of male versus female educational administrators to deternine whether there were significant differences in their profiles, and (2) to examine whether males and females were equally good candidates for administrative jobs, which positions are often associated with a high degree of job-related stress. A 35-item questionnaire, known as the Administrative Stress Index (ASI) was sent to all members of the Confederation of Oregon School Administrators (n = 1855). The 1156 usable questionnaires were returned. Approximatley 9.3% (or 108) of the respondents were female. One-way analyses of variance showed that female administrators experienced substantially lower levels of self-perceived occupational stress than their male counterparts. Findings were disucssed primarily in terms of implications for recruitment of women into administrative positions. 相似文献
