The scope of Dulany's (1968) Theory of Propositional Control was examined using 54 . Significance of the reinforcer was manipulated orthogonally to value of the reinforcer. With a six attribute concept attainment task did not learn in either of two significant ways: a performance change over blocks, nor the acquisition of a rule of reinforcement. Children of and learned in both of the above senses. In addition, for the latter subjects the central equations of the theory held with strength and subjects' intentions accounted for more variance in performance than did the experimental manipulations. In supplementary experiments using a simplified task some learned. When only the who learned to a criterion were examined the central equations of the theory were nearly as strong as for subjects at ages and . There was no evidence for learning without awareness at any age level. 相似文献

Subjects at three age levels were administered picture pair or word pair discrimination lists. They pronounced or pointed as a method of choice, and they pronounced or pointed at the correct item (or remained silent) during rehearsal. The results indicated that with picture pairs, pronunciation facilitated learning as a method of choice and a type of rehearsal in nursery school Ss. For fifth grade and college Ss, there was no significant difference between pronouncing and pointing as a method of choice. However, spoken rehearsal was superior to control performance for fifth grade Ss. College Ss performed equally well in the control and pronouncing conditions, but pointing during rehearsal produced significantly more errors than pronouncing. Word pairs produced no significant pronunciation effects. These results were discussed within an internalization of speech perspective. 相似文献

Reaction times for two right-handed subjects who received 6000 trials of dichotic stop-vowels were obtained under response conditions involving the left hand, right hand, and neck muscles. Results indicated latencies were shorter (150+ msec) when targets were presented to the right rather than the left ear. Large and stable differences in latencies remained invariant with the mode of response. Reaction times did not vary as a function of the target's place or manner of articulation. The relationship between obtained measures of latency and percentage correct ruled out speed-accuracy trade-offs as a source of the obtained differences in latencies. 相似文献

Summary In this paper I address some shortcomings in Larry Laudan’s normative naturalism. I make it clear that Laudan’s rejection of the “meta-methodology thesis”, or MMT is unnecessary, and that a reformulated version MMT can be sustained. I contend that a major difficulty that attends Laudan’s account is his contention that a naturalistic philosophy of science cannot accommodate any a priori justification of methodological rules, and consider what sort of naturalism might best replace Laudan’s. To do this, I discuss Michael Friedman’s account of a relativised a priori and show that it is consistent with naturalistic philosophy of science and that it can help form the basis of a plausible normative naturalism. In particular, this discussion shows that Laudan’s rejection of any a priori justification of methodological rules is unjustified and inconsistent with scientific practice. Finally, I point the way to a version of normative naturalism that includes MMT and accounts for the role of constitutive a priori principles within science. 相似文献

Regression analysis was used to examine simultaneously the effects of supervisors' and subordinates' ethnicity and sex on organizational communication, supervisory-rated performance, and job satisfaction. The study indicates that female subordinates differentially perceive organizational communication. It also identifies interactions between the sex of the supervisor and subordinate on communication and between the ethnicity of the superior and subordinate on supervisory-rated performance. There were limited impacts of sex and ethnicity on job satisfaction. 相似文献

We argue for a naturalistic account for appraising scientific methods that carries non-trivial normative force. We develop
our approach by comparison with Laudan’s (American Philosophical Quarterly 24:19–31, 1987, Philosophy of Science 57:20–33,
1990) “normative naturalism” based on correlating means (various scientific methods) with ends (e.g., reliability). We argue
that such a meta-methodology based on means–ends correlations is unreliable and cannot achieve its normative goals. We suggest
another approach for meta-methodology based on a conglomeration of tools and strategies (from statistical modeling, experimental
design, and related fields) that affords forward looking procedures for learning from error and for controlling error. The
resulting “error statistical” appraisal is empirical—methods are appraised by examining their capacities to control error.
At the same time, this account is normative, in that the strategies that pass muster are claims about how actually to proceed
in given contexts to reach reliable inferences from limited data. 相似文献
