Psychology seeks to justify its claims to privilege as a social institution largely on the basis of its scientific knowledge claims. These knowledge claims tend to be based on, and to reflect a particular view about the nature of science which is under increasing challenge. This situation is discussed and some of its implications examined. 相似文献

The influence of an isolated word’s meaning on lexical decision reaction time (RT) was demonstrated through four experiments. Subjects in two experiments made lexical decision judgments, those in a third experiment pronounced the words used in the lexical decision task, and those in a fourth experiment quickly pronounced their first associative response to the words. Differences in lexical access time for the words were measured with the pronunciation task, and differences in meaning were assessed with the association task. Multiple regression analyses of lexical decision RT were conducted using associative RT, pronunciation RT, and other target word properties (printed frequency, length, instance dominance, and number of dictionary meanings) as predictor variables. These analyses revealed a relationship between lexical decision RT and associative RT after the effects of other variables had been partialed out. In addition, word frequency continued to have a significant relationship to lexical decision RT beyond that shared with pronunciation RT and the other variables. The results of these experiments indicate that at least some of the effect of word meaning and word frequency in lexical decision is attributable to a decision stage following lexical access. 相似文献

The effect of environmental enrichment on normal rats, rats that received hemidecortication at birth, and rats that received hemidecortication when adult was studied in the Morris water task, which is a spatial navigation task requiring the use of distal cues for successful performance. Enrichment was achieved by housing the rats for 90 days in a large outdoor compound that was designed to model a natural environment. Adult hemidecorticated lab-raised rats were severely impaired in the acquisition of the task but neonatally hemidecorticated rats, although also impaired, showed significant sparing. Postsurgical, but not presurgical, enrichment of adult hemidecorticated rats significantly enhanced their recovery. Enrichment had little effect on neonatally decorticated rats or on normal rats. Although there were no gross anatomical changes associated with enrichment, the paradigm provides both a robust phenomena and a cortically dependent task that is ideal for investigating the processes in the remaining intact hemisphere that must support recovery. 相似文献

This study examined the impact of nonsexist curricula and teacher's sex on children's sex role learning. Thirty-two boys and 32 girls, aged three to five, were equally divided among four programs: nonsexist curriculum, female director; nonsexist curriculum, male director; control curriculum, female director; and control curriculum, male director. Sex role discrimination and preference were measured at the beginning and end of a six-month period. Exposure to the nonsexist curriculum produced significantly greater reductions in sex stereotyping on all measures than exposure to the control curriculum. Moreover, children in the male-directed nonsexist program displayed greater decreases in stereotypic knowledge and preference for sex-typed children's activities than those in the female-directed nonsexist program, while children in the male-directed control program showed more stereotypic increases on these measures than their counterparts in the female-directed control program. Finally, children under the direction of an opposite-sex teacher exhibited less stereotypic changes in preference for adult activities than children under the direction of a same-sex teacher. Implications for early childhood programs are discussed.This research was partially supported by an Oregon State University Foundation grant from the Shell Foundation and a grant from the Milne Computer Center. 相似文献

The effects of a graduated prompting treatment procedure were analyzed in three phases of an experiment on the training and generalization of reaching-grasp responding in 2- to 4-year-old blind, severely or profoundly retarded children. In Phase 1, we used a multiple-baseline across-subjects design to investigate the effectiveness of the treatment on midline reach-grasp responding. In Phase 2, we used a reversal design to investigate the effects of repeated implementations and withdrawals of the treatment. In both phases, generalization to right and left positions was measured. In Phase 3, in a multiple-baseline across-responses design, the treatment was implemented in right and left positions. Also in Phase 3, shift of stimulus control from toy-sound to verbal instructions was measured. The results showed that (a) the graduated prompting procedure was effective in training reach-grasp responding in all three children; (b) for one child, the effects were durable over repeated applications of the treatment procedure, but were not maintained during withdrawals; (c) for another child, the treatment procedure was effective in teaching reach-grasp responding in all three positions; and (d) for the same child, training of reach-grasp responding generalized to toys presented without sound, given only the verbal instruction. 相似文献

Two experiments assessed infant sensitivity to figural coherence in point-light displays moving as if attached to the major joints of a walking person. Experiment 1 tested whether 3- and 5-month-old infants could discriminate between upright and inverted versions of the walker in both moving and static displays. Using an infant-control habituation paradigm, it was found that both ages discriminated the moving but not the static displays. Experiment 2 was designed to clarify whether or not structural invariants were extracted from these displays. The results revealed that (1) moving point-light displays with equivalent motions but different topographic relations were discriminated while (2) static versions were not, and (3) arrays that varied in the amount of motion present in different portions of the display were also not discriminated. These results are interpreted as indicating that young infants are sensitive to figural coherence in displays of biomechanical motion. 相似文献

Abstract. The broad character of the arguments used by sociobiologists is assessed, particularly in relation to criticisms coming from anthropology. The implications of sociobiology for theology are developed with respect to the general impact of evolutionary ideas, the reductionist assumptions of sociobiologists, whether or not "survival" can be a value, and more holistic accounts of the physical and biological grounding of the mental and spiritual lives of human beings. 相似文献

Abstract. The basic features of thermodynamics as the "science of the possible" are outlined with a special emphasis on the role of the concept of entropy as a measure of irreversibility in natural processes and its relation to "order," precisely defined. Natural processes may lead to an increase in complexity, and this concept has a subtle relationship to those of order, organization, and information. These concepts are analyzed with respect to their relation to biological evolution, together with other ways of attempting to quantify it. Thermodynamic interpretations of evolution are described and critically compared, and the significance of dissipative structures, of "order through fluctuations," is emphasized in relation both to the evolutionary succession of temporarily stable forms and to kinetic mechanisms producing new patterns. 相似文献
