This paper brings some data to bear on the criticisms, claims, and arguments that Skinner (a) denied or dismissed biological participation in behavior, (b) addressed it only late in his career or more often later than earlier, or (c) addressed it only because of the overwhelming evidence for it or the criticisms that he had overlooked it. For this, we coded Skinner's every primary-source publication for three content categories (i.e., genetics, physiology, and evolution) and for the extent to which he addressed them (i.e., in publication titles, substantively, or in passing). Our findings are that Skinner addressed biological participation in over a third of his publications throughout his career, albeit more often later than earlier. The latter, however, is accounted for by an increase in his base rate of publication and in general conditions and specific events in his career, psychology, and science. The discussion addresses our research methods; the reasons for and refutations of the criticisms, claims, and arguments; and their sources. 相似文献

Although there has been a rapid increase in funding and attention to after-school programs, there is little understanding of how after-school programs impact children's developmental trajectories. The heterogeneity of American children makes it very unlikely that all children need after-school programming or that there is but one brand of after-school programming suitable for all youth. We discuss the numerous developmental and contextual factors that may influence which children benefit most from after-school programs as well as the nature of the after-school programs most beneficial to children's needs. The value of utilizing an ecological and developmental perspective to after-school program evaluation are presented, including the need for improved research designs and more detailed analyses of program type and services as well as a more complete determination of which children benefit the most from after-school participation. 相似文献

Life span developmental profiles were constructed for 305 participants (ages 4-95) for a battery of paced and unpaced perceptual-motor timing tasks that included synchronize-continue tapping at a wide range of target event rates. Two life span hypotheses, derived from an entrainment theory of timing and event tracking, were tested. A preferred period hypothesis predicted a monotonic slowing of a preferred rate (tempo) of event tracking across the life span. An entrainment region hypothesis predicted a quadratic profile in the range of event rates that produced effective timing across the life span; specifically, age-specific entrainment regions should be narrower in childhood and late adulthood than in midlife. Findings across tasks provide converging support for both hypotheses. Implications of these findings are discussed for understanding critical periods in development and age-related slowing of event timing. 相似文献

Recent research indicates that motor areas are activated in some types of mental rotation. Many of these studies have required participants to perform egocentric transformations of body parts or whole bodies; however, motor activation also has been found with nonbody objects when participants explicitly relate the objects to their hands. The current study used positron emission tomography (PET) to examine whether such egocentric motor strategies can be transferred implicitly from one type of mental rotation to another. Two groups of participants were tested. In the Hand-Object group, participants performed imaginal rotations of pictures of hands; following this, they then made similar judgments of pictures of Shepard-Metzler objects. The Object-Object group performed the rotation task for two sets of Shepard-Metzler objects only. When the second condition in each group (which always required rotating Shepard-Metzler objects) was compared, motor areas (Area 6 and M1) were found to be activated only in the Hand-Object group. These findings suggest that motor strategies can be covertly transferred to imaginal transformations of nonbody objects. 相似文献

Recent experiments have shown that people iconically modulate their prosody corresponding with the meaning of their utterance (e.g., Shintel et al., 2006). This article reports findings from a story reading task that expands the investigation of iconic prosody to abstract meanings in addition to concrete ones. Participants read stories that contrasted along concrete and abstract semantic dimensions of speed (e.g., a fast drive, slow career progress) and size (e.g., a small grasshopper, an important contract). Participants read fast stories at a faster rate than slow stories, and big stories with a lower pitch than small stories. The effect of speed was distributed across the stories, including portions that were identical across stories, whereas the size effect was localized to size‐related words. Overall, these findings enrich the documentation of iconicity in spoken language and bear on our understanding of the relationship between gesture and speech. 相似文献

In this study, we used event-related potentials to examine how different dimensions of emotion—valence and arousal—influence different stages of word processing under different task demands. In two experiments, two groups of participants viewed the same single emotional and neutral words while carrying out different tasks. In both experiments, valence (pleasant, unpleasant, and neutral) was fully crossed with arousal (high and low). We found that the task made a substantial contribution to how valence and arousal modulated the late positive complex (LPC), which is thought to reflect sustained evaluative processing (particularly of emotional stimuli). When participants performed a semantic categorization task in which emotion was not directly relevant to task performance, the LPC showed a larger amplitude for high-arousal than for low-arousal words, but no effect of valence. In contrast, when participants performed an overt valence categorization task, the LPC showed a large effect of valence (with unpleasant words eliciting the largest positivity), but no effect of arousal. These data show not only that valence and arousal act independently to influence word processing, but that their relative contributions to prolonged evaluative neural processes are strongly influenced by the situational demands (and by individual differences, as revealed in a subsequent analysis of subjective judgments). 相似文献

The authors examined the association between multicultural counseling competence (MCC) and mindfulness. Previous authors have maintained a conceptual link between MCC and mindfulness; however, this is the first empirical analysis of the relationship between MCC and mindfulness. Results revealed that, after race/ethnicity, multicultural course completion, and empathy were controlled, components of mindfulness were correlated with multicultural awareness and multicultural knowledge. These results have implications for counselor education, counseling practice, and future research. 相似文献

A number of philosophers have claimed that non-evidential considerations cannot play a role in doxastic deliberation as motivating reasons to believe a proposition. This claim, interesting in its own right, naturally lends itself to use in a range of arguments for a wide array of substantive philosophical theses. I argue, by way of a counterexample, that the claim to which all these arguments appeal is false. I then consider, and reply to, seven objections to my counterexample. Finally, as a way of softening the blow, I show how the counterexample itself suggests a plausible diagnosis of why this claim has seemed so plausible to so many. 相似文献
