I am responding to the Hamre article on the identification and prevention o stuttering and to what was said by those who commented in the recent Special Forum Issue. My discussion will be in terms of my understanding and one of my major career objectives, that of translating reported research and clinical experience in a meaningful and useful way for students and professional clinicians. 相似文献

Converging operations on a basic level in event taxonomies 总被引:1,自引:0,他引:1
Research on object concepts has identified one level of abstraction as "basic" in cognition and communication. We investigated whether concepts for routine social events have a basic level by replicating the converging operations used to investigate object concepts. In Experiment 1, subjects were presented with event names from a taxonomy and were asked to list the actions comprising the event. Many more actions were listed at the middle than at the highest taxonomic level, without a further increase at the most specific level, paralleling the pattern of superordinate-, basic-, and subordinate-level object concepts. From these action lists, brief stories were composed for each event. In Experiment 2, subjects made pairwise similarity judgments on the stories. The mean similarity of events increased with specificity, as expected. But differentiation of categories (within-category similarity compared to between-category similarity) was highest for super-ordinates, contrary to results with object categories. In Experiment 3, subjects were fastest in recognizing actions as belonging to events named at the basic level. In Experiment 4, subjects predominantly chose basic-level terms to name stories. We conclude that event taxonomies do show basic-level structure, albeit a less sharply defined and less stable structure than in object taxonomies. The benefits and hazards of extending models of object concepts to other entities, such as social events, are discussed. 相似文献

Ascertained if being a member of a statistical minority influences children's adjustment in school, as measured by the AML, a teacher-administered adjustment rating scale. Teachers from a southwest school district evaluated elementary students on aggressive, acting-out behaviors, moody-internalized behaviors, and learning difficulties. Analyses conducted on 376 students revealed significant effects of statistical minority status on certain dimensions of adjustment ratings for both Hispanic and Anglo students. Hispanic students in the statistical minority received poorer ratings on the moodiness dimension of the AML than nonminority Hispanic students. Anglo students in the statistical minority received poorer ratings on the aggression dimension of the AML than nonminority Anglo students. These results were interpreted in terms of cultural differences in coping with statistical minority status. Traits commonly exhibited within a culture may intensify and be perceived as maladaptive when stress resulting from being a minority occurs. Implications of the finding that statistical minority status within the school environment influences adjustment are discussed. 相似文献

Relationships of serum and saliva to personality were examined among 401 college students in four laboratory studies and 5,236 military veterans in one archival study. Among the students, there were few relationships between testosterone and traditional personality measures. Among the veterans, MMPI scores and DSM-III diagnoses showed testosterone related to drug and alcohol abuse, antisocial and generally intemperate behavior, and effective disorders. Consistent with social control theory, correlations were higher among veterans who were lower in socioeconomic status. It appears likely that testosterone has innate effects that are socially undesirable but can be attenuated by bonds between the individual and society. Effect sizes were small, suggesting that testosterone will have noticeable effects only in large populations or individuals who differ markedly from the population mean. Further research should focus upon antisocial correlates of testosterone and conditions that produce marked changes in testosterone levels. 相似文献

Visual illusions provide evidence of perceptual processes, especially the use of knowledge about objects and the working rules for seeing. The classification of phenomena is necessary for any science because it facilitates induction and deduction. The phenomena of illusions are no exception. It is hoped that the tentative classification presented here may stimulate further research and raise new questions by revealing gaps in the conceptual structure of how perception proceeds. Finally, a speculation is offered for the functional use of sensations, the qualia of consciousness. 相似文献

Recent studies suggest that performance attendant on visual word perception is affected not only by feedforward inconsistency (i.e., multiple ways to pronounce a spelling) but also by feedback inconsistency (i.e., multiple ways to spell a pronunciation). In the present study, we provide a statistical analysis of these types of inconsistency for all monosyllabic English words. This database can be used as a tool for controlling, selecting, and constructing stimulus materials for psycholinguistic and neuropsychological research. Such large-scale statistical analyses are necessary devices for developing metrics of inconsistency, for generating hypotheses for psycholinguistic experiments, and for building models of word perception, speech perception, and spelling. 相似文献

This study describes the results of a retrospective review of patients' charts who had an advanced directive (AD) and who were hospitalized in a tertiary, acute care teaching hospital. The purpose of the review was to understand from clinical, sociological, ethical and legal perspectives the nature and utility of ADs. Findings and implications of the review are discussed in terms of: patient demographics; diagnoses; quality of ADs; influence of ADs on clinical decisions; and legal aspects of ADs. 相似文献

present research examined the role of hippocampal NMDA-dependent synaptic potentiation on appetitive instrumental conditioning
under a continuous reinforcement schedule. In the first experiment, low (.025 mg.kg) or moderate (.05 mg/kg) dosages of the
NMDA receptor antagonist, MK801, failed to increase the number of training days required to reach acquisition criterion; number
of training days required to reach criterion for extinction were also unaffected. In the second experiment, a higher dosage
(.10 mg/kg) of MK801 or induction of long-term potentiation failed to alter the number of responses occurring during acquisition.
These data suggest that hippocampal synaptic potentiation does not play a prominent role in instrumental learning with simple
contingency conditions. It is suggested that hippocampal LTP reflects a perceptual process that contributes differentially
to spatial cognition, classical and instrumental conditioning. 相似文献
