Study 1 was conducted to examine the contribution of the joint condition of supervisor close monitoring and the presence of creative coworkers to employees' creativity. In addition to replicating Study 1's results, Study 2 examined (a) the joint condition of supervisor developmental feedback and presence of creative coworkers and (b) whether creative personality moderated the contributions of the 2 joint conditions. Converging results from the 2 field studies demonstrated that when creative coworkers were present, the less supervisors engaged in close monitoring, the more employees exhibited creativity. Study 2 also found that the contribution of this joint condition was stronger for employees with less creative personalities and that when creative coworkers were present, the more supervisors provided developmental feedback, the more employees exhibited creativity.  相似文献

Effects of experience on fetal voice recognition   总被引:1,自引:0,他引:1  
Abstract - The ability of human fetuses to recognize their own mother's voice was examined. Sixty term fetuses were assigned to one of two conditions during which they were exposed to a tape recording of their mother or a female stranger reading a passage. Voice stimuli were delivered through a loudspeaker held approximately 10 cm above the maternal abdomen and played at an average of 95 dB SPL. Each condition consisted of three 2-min periods: no stimulus, voice (mother or stranger), and no stimulus. Fetal heart rate increased in response to the mother's voice and decreased in response to the stranger's; both responses were sustained for 4 min. The finding of differential behavior in response to a familiar versus a novel voice provides evidence that experience influences fetal voice processing. It supports an epigenetic model of speech perception, presuming an interaction between genetic expression of neural development and species-specific experience.  相似文献

Early life experience affects behavior and brain mechanisms. Handling rats during the first three weeks in life can slow age-related cognitive decline (as measured by a hippocampal-dependent spatial learning task) and reduce age-related hippocampal neuron loss. It is not clear, however, whether this early environmental influence on learning is selective for old age or is more general, affecting cognitive development during infancy and young adulthood as well. We briefly exposed neonatal rats to a novel non-home environment for 3 min daily during the first three weeks of life (as a component of the handling method). We found that this brief early environmental manipulation resulted in enhanced hippocampal-dependent learning immediately after weaning and that this learning enhancement persisted into adulthood. These results suggest that subtle early life events can affect cognitive development in all developmental stages and that changes in neural mechanisms other than neuron number are likely to mediate the learning enhancement at multiple developmental stages.  相似文献

We present observations on the use of racial and cultural stereotypes in psychoanalytic psychotherapy with patients from the majority culture and with those from minority backgrounds. Earlier work has centered on black/white patient dyads and has not taken other possible combinations into account. "Race" and "culture" have sometimes been used synonymously. Our clinical experience indicates that there is some overlap in the themes of transferences to us as members of different racial minorities. We note, however, that for the African-American therapist, projections are more often based on racial stereotypes, whereas for the Chinese-American therapist, projections are based more on cultural assumptions. When careful attention is paid to the manifestations of racial and cultural stereotyping, much can be learned about the patient's inner life, to the benefit of the analytic work.  相似文献

In their paper “Do Bilinguals Automatically Activate Their Native Language When They Are Not Using it?”, Costa, Pannunzi, Deco, and Pickering (Cognitive Science, 2017) proposed a reinterpretation of Thierry and Wu's (2004, 2007) finding of native language‐based (Chinese, L1) ERP effects when they tested Chinese–English late bilinguals exclusively in their second language (English, L2). Using simulations in a six‐node Hebbian learning model (three L1 nodes, three L2 nodes), Costa et al. suggested that form overlaps in L1 between otherwise unrelated words create a persistent relationship between their L2 translations. In this scenario, words in the nascent L2 lexicon overlapping in their L1 translations would become linked during learning because of the form overlap in L1; once the L2 words are learned, the direct link between them would be sufficient to generate robust, apparently “L1‐mediated” priming without requiring any activation of L1 translations. Costa et al. contend that links between L2 words remain beyond the learning phase, even after links to L1 representations have been severed, and thus that their model affords an alternative account to (but not a rebuttal of) Thierry and Wu's claim of language non‐selective activation—or automatic activation of translation equivalents—in late bilinguals. In this response, we build on Costa et al.'s original simulation code, showing that it can only reproduce L1‐independent priming when implementing the L1 disconnection in their particular way. By contrast, when severing inter‐language connections bidirectionally, their model fails to retain any sizeable influence of L1 form overlap on L2 activations. The model is not the theory, however, and we discuss several issues that would need to be addressed in further attempts to model language non‐selective activation in late bilinguals.  相似文献

It is established that stress impairs spatial learning and memory via the hypothalamus-pituitary-adrenal axis response. Dopamine D1 receptors were also shown to be responsible for a stress-induced deficit of working memory. However, whether stress affects the subsequent emotional learning and memory is not elucidated yet. Here, we employed the well-established one-trial step-through task to study the effect of an acute psychological stress (induced by tail hanging for 5, 10, or 20?min) on emotional learning and memory, and the possible mechanisms as well. We demonstrated that tail hanging induced an obvious stress response. Either an acute tail-hanging stress or a single dose of intraperitoneally injected dopamine D1 receptor antagonist (SCH23390) significantly decreased the step-through latency in the one-trial step-through task. However, SCH23390 prevented the acute tail-hanging stress-induced decrease in the step-through latency. In addition, the effects of tail-hanging stress and/or SCH23390 on the changes in step-through latency were not through non-memory factors such as nociceptive perception and motor function. Our data indicate that the hyperactivation of dopamine D1 receptors mediated the stress-induced deficit of emotional learning and memory. This study may have clinical significance given that psychological stress is considered to play a role in susceptibility to some mental diseases such as depression and post-traumatic stress disorder.  相似文献

Although the study of brain states is an old one in neuroscience, there has been growing interest in brain state specification owing to MRI studies tracing brain connectivity at rest. In this review, we summarize recent research on three relatively well-described brain states: the resting, alert, and meditation states. We explore the neural correlates of maintaining a state or switching between states, and argue that the anterior cingulate cortex and striatum play a critical role in state maintenance, whereas the insula has a major role in switching between states. Brain state may serve as a predictor of performance in a variety of perceptual, memory, and problem solving tasks. Thus, understanding brain states is critical for understanding human performance.  相似文献
