“If one believes in the Prince of Peace one must stop committing crimes in the name of the Prince of Peace. The Christian Church still rules this world, it still has the power to change the structure of South Africa.” James Baldwin in his address to the Fourth Assembly of the World Council of Churches, Uppsala, 1968. 相似文献
An automated threshold method has been developed for determining the maximum rate of speech understood by individual listeners. Two experiments were undertaken to determine whether the threshold was related to the comprehension of speech or to speech intelligibility. The first experiment compared thresholds of two types of rapid speech reportedly different in intelligibility: simple speeded speech and speech compressed by the sampling method. The second experiment sought to determine the relationship of the threshold to traditional comprehension measures. The results are discussed in terms of the intelligibility and comprehensibility of speech. 相似文献
Goal attainment scaling (GAS) is an individually tailored way to measure treatment gains, using a highly standardized procedure. An advantage of the method is that it takes into account individual characteristics of the patients, and at the same time the data are suitable for quantitative analysis and comparable across patients. Despite the wide acceptance and use of the method in the evaluation of psychotherapy, data on its psychometric properties are rather scarce. In the current study, GAS was used as one of several outcome measures in a research project on the effectiveness of various treatments for panic disorder with agoraphobia. Guidelines for GAS are presented as well as data on the reliability and validity of the procedure. Results indicate that the procedure is reliable, valid, and sensitive to the improvement of patients during treatment. Comparison of GAS with standardized measures revealed considerable concordance, although the clinical end status of patients diverged somewhat dependent on the measure considered. 相似文献
Unpredictability of the intensity of an aversive event might be an important factor in producing negative effects of the event, especially if the UCS becomes stronger than could have been expected. The present experiment tested the hypothesis that unpredictability of intensity of a painful stimulus contributes to avoidance behaviour. The experiment was concealed in a shock working-up procedure, which was done to assess the pain level subjects were willing to tolerate in a subsequent experiment. The experimental subjects, who received an unannounced sudden increase of the pain stimulus during the working-up procedure, tolerated less pain on a subjective as well as on an objective level (avoidance of high levels of pain) than the control subjects, who received the stimuli in a predictable pattern. The results support the hypothesis that unpredictability of intensity of an aversive event contributes to avoidance behaviour. 相似文献
Undergraduate university students (N = 103) participated in a study of the relationship between test anxiety and the variables of trait anxiety, self-esteem, locus of control, mental ability, and gender. Results indicated bivariate associations between total test anxiety and the other measures except for mental ability. Further analyses revealed independent relationships between the "worry" component of test anxiety and the variables of trait anxiety, internality, chance, and mental ability. We also found independent associations between the "emotionality" aspect of test anxiety and the measures of trait anxiety and chance. 相似文献
Summary In Experiment 1, the performance of young retarded readers on speech-segmentation tasks was compared with the performance of normal subjects matched for chronological age (CA) and with subjects matched for reading age (RA). Retarded readers were poorer than both control groups in consonant deletion, while there was no difference between the groups on a rhyme-judgement task and a syllabic-vowel-reproduction task. In Experiment 2, another group of reading retarded children was compared with CA and RA controls on the classification of pseudowords, either by common phoneme or by overall phonetic similarity. The retarded readers made fewer classifications based on common phoneme than both control groups, while there was no difference between the groups in classifications based on overall phonetic similarity. In Experiment 3, adult developmental dyslexics were compared with normal adults in the tasks of Experiments 1 and 2. The dyslexics made fewer classifications based on a common phoneme than the normals, while no difference was found in classifications based on overall phonetic similarity. 相似文献
Did Descartes manage to overcome the skeptics? If we understand “overcome” in the sense of “refute,” the answer is no, since his hyperbolic doubt harbors several blind spots and is, therefore, not as radical as is commonly argued. In this way, the victory of the cogito is perhaps less decisive and fruitful than it is claimed. If we understand “overcome” in the sense of “remove” or “move beyond,” the answer is yes. Descartes has overcome skepticism, but at the cost of a decision, a sort of bet made in favor of reason based on a confidence in the human mind that is never really subverted. This faith in reason, truth, and specific epistemological principles in Descartes’ philosophy constitute what Wittgenstein calls “hinges,” which are indispensable for doubting and searching for truth. In this sense, Descartes’ anti-skepticism is more a confidence in reason in order to save the possibility of science than the result of a logical refutation.
Research supports equivalence-based instruction (EBI) and matrix training for increased listening and speaking skills in children with cochlear implants (CI). We incorporated errorless procedures to optimize the EBI and evaluated the effects on the auditory comprehension and verbal responding at-sentences level in six CI children who were readers and showed inaccurate tacting. Subject-verb-object sentences were arranged in two matrices; diagonal combinations were trained and evaluated non-diagonal combinations. EBI included stimulus fading and exclusion to directly teach the dictated sentence-picture matching; written-sentences construction upon dictation also was taught. Probes assessed the derived stimulus-stimulus and stimulus-response relations. All participants learned the auditory-visual discriminations and the exclusion resulted in fewer errors than on a stimulus fading procedure. Five participants formed equivalence classes and increased verbal responding to equivalent stimuli, especially pictures tacting. They also showed recombinative generalization for both matrices. Professionals can incorporate errorless procedures to EBI for improving sentence comprehension, tacting, and productivity in CI children. 相似文献
