This paper attempts to demonstrate the critical significance of early advances in quantum physics for Alfred North Whiteheads development of the categories of his metaphysics and to illustrate the capacity of his system to serve as a bridge between the sciences and the humanities by relating specific Whiteheadian categories to concrete microphysical behavior with special reference to the notion of freedom.  相似文献

Three experiments were conducted employing a continuous measure of conditional stimulus/unconditional stimulus (CS/US) contingencies as perceived by the subject (i.e., subjective contingency or SC). It is argued that direct measurement of relational learning, as indexed by SC, can lead to a better understanding of Pavlovian conditioning processes. The first two experiments applied this approach to a methodologic controversy, raising the debate from a procedure-based argument to testing what the subject actually learns about CS/US relationships. While the issue was not resolved, testable hypotheses for future research were generated from the data. The third experiment contrasted the contingency stimulus-stimulus (S-S) account of Pavlovian conditioning with an earlier stimulus-response (S-R) continguity-reinforcement account. In this experiment, both SC and skin resistance were measured. Evidence for the existence of both cognitive-propositional and response-learning processes in conditioning was obtained.  相似文献

Women are no longer underrepresented in student-personnel preparation programs. Although this situation is noteworthy, it may not be without potentially frustrating consequences for the increased number of female master's degree graduates who are seeking a limited number of entry-level positions. Whether the increase in women will have deleterious effects on placement remains to be seen. In the meantime, women (and men) should be made aware of the inherent free-market employment risks when contemplating a career in student-personnel work.  相似文献

Young boys with normal male physical status who manifest feminine gender-role behavior and verbalize a cross-gender identity are high-risk for later adult sexual adjustment problems, e.g., transsexualism and homosexual conflicts (Bakwin, 1968; Lebovitz, 1972; Stoller, 1968; Zuger, 1966). In the only published experimental treatment studies on child gender disturbance in which replication procedures were used, Rekers and his colleagues empirically demonstrated external stimulus control and reinforcement control over pronounced feminine behavior in young boys with serious gender identity and behavior disturbance (Rekers and Lovaas, 1974; Rekers, Lovaas and Low, 1974; Rekers, Willis, Yates, Rosen and Low, in press; Rekers, Yates, Willis, Rosen and Taubman, 1976). To potentially minimize the previously reported stimulus specificity of the extrinsic reinforcement effects, this study introduces, for the first time, behavioral self-control strategies to decrease feminine behavior in a cross-gender identified boy. A 6-year-old boy was taught to self-monitor his own sex-role behavior, and then to self-reinforce gender-appropriate responding. A behavioral cueing procedure was used during the initial phases of the training of self-monitoring.  相似文献

Piaget attributes perseverative error in infant manual search to the failure of the infant to conceive of objects as permanent entities which retain their identity when hidden at successive locations A and B. An experiment was performed to test this explanation in which search was compared under three conditions: when the object was hidden at A and B, when the object was covered but visible at A and B, and when the object was visible and uncovered at A and B. Errors occurred under all three conditions taking the form of a conflict in which infants searched persistently either at A or at B. The conflict was at a maximum when the object was hidden, but was evident even when the object was visible but covered. It is suggested that errors may reflect lack of coordination between egocentric and visual frames of reference in relation to which the object is located.  相似文献

Masculine and feminine subgroups of males and females were selected from samples of high school and college students on the basis of composite scores from several M—F scales. They were compared on intelligence as measured by a verbal test, Terman's Concept Mastery Test, and a nonverbal test, D-48. Results did not support previous findings of sex differences in intelligence but showed that masculine subgroups of both sexes scored higher of the nonverbal test.  相似文献

Psychophysical thresholds for the detection of sinusoidal vibration of the thenar eminence of the hand were determined for children and adults. The subjects in the child group were between 8 and 11 years old, and the adults were between 20 and 39 years old. Measurements were made for vibration frequencies ranging from 18 to 700 Hz and stimulus durations ranging from 28 to 1,000 msec. For both children and adults, thresholds were a Il-shaped function of stimulus frequency. However, the exact form of the function was influenced by the age of the subjects. At frequencies above 200 Hz, thresholds were virtually identical for children and adults, but below this frequency children were more sensitive than adults. This finding, in combination with known changes in the anatomy of the Pacinian corpuscle with age, is in agreement with a filter model of this cutaneous receptor. Furthermore, variation of stimulus duration resulted in data in agreement with the theory that two classes of mechanoreceptors, Pacinian and non-Pacinian, mediate the perception of vibration.  相似文献

The syllabic structure and phonemic inventory of one child were analyzed at the beginning of word production and compared with similar records reported in the literature. The data appear to favor an interactionist view of lexical development which recognizes the contribution of particular syllabic forms to the acquisition of consonantal phonemes and the role these phonemes play in expanded syllabic form. The discussion argues for the primacy of CV as the dominant unit of production and identifies a number of constraints on syllabic forms and a set of conspiratorial rules which assure the production of these forms. Further, it is argued that certain strategies operating within the constraints to particular syllabic forms result in the ordered development of syllabic structures.  相似文献

This study investigates the influence of attention loading on the established intersensory effects of passive bodily rotation on choice reaction time (RT) to visual motion. Subjects sat at the center of rotation in an enclosed rotating chamber and observed an oscilloscope on which were, in the center, a tracking display and, 10° left of center, a RT line. Three tracking tasks and a no-tracking control condition were presented to all subjects in combination with the RT task, which occurred with and without concurrent cab rotations. Choice RT to. line motions was inhibited (p < .001) both when there was simultaneous vestibular stimulation and when there was a tracking task; response latencies lengthened progressively with increased similarity between the RT and tracking tasks. However, the attention conditions did not affect the intersensory effect; the significance of this for the nature of the sensory interaction is discussed.  相似文献
