A female superiority in verbal ability is reported on many tests. It has been hypothesized that the female brain is more functionally symmetrical for language then the male, and that this is the cause of the alleged superiority. Recent research has suggested that factors other than sex are involved: handedness, age of maturity, and endocrine influences. It is not yet clear whether, despite its biological correlates, the female superiortiy is innate. 相似文献

A Big Regulatory Tool-Box for a Small Technology 总被引:1,自引:0,他引:1
There is little doubt that the development and commercialisation of nanotechnologies is challenging traditional state-based
regulatory regimes. Yet governments currently appear to be taking a non-interventionist approach to directly regulating this
emerging technology. This paper argues that a large regulatory toolbox is available for governing this small technology and
that as nanotechnologies evolve, many regulatory advances are likely to occur outside of government. It notes the scientific
uncertainties facing us as we contemplate nanotechnology regulatory matters and then examines the notion of regulation itself,
suggesting new ways to frame our understanding of both regulation and the regulatory tools relevant to nanotechnologies. By
drawing upon three different conceptual lenses of regulation, the paper articulates a wide range of potential regulatory tools
at hand. It also focuses particularly on the ways various tools are currently being used or perhaps may be employed in the
future. The strengths and weaknesses characterising these tools is examined as well as the different actors involved. The
paper concludes that we will increasingly face debate over what is likely to work most effectively in regulating nano technologies,
the legitimacy of these different potential approaches, and the speed at which these different regimes may be employed.

Functional specificity of the visual word form area: general activation for words and symbols but specific network activation for words 总被引:3,自引:0,他引:3
The functional specificity of the brain region known as the Visual Word Form Area (VWFA) was examined using fMRI. We explored whether this area serves a general role in processing symbolic stimuli, rather than being selective for the processing of words. Brain activity was measured during a visual 1-back task to English words, meaningful symbols (e.g., $, %), digits, words in an unfamiliar language (Hebrew), and geometric control stimuli. Mean activity in the functionally defined VWFA, as well as a pattern of whole-brain activity identified using a multivariate technique, did not differ for words and symbols, but was distinguished from that seen with other stimuli. However, functional connectivity analysis of this region identified a network of regions that was specific to words, including the left hippocampus, left lateral temporal, and left prefrontal cortex. Results support the hypothesis that activity in the VWFA plays a general role in processing abstract stimuli; however, the left VWFA is part of a unique network of brain regions active only during the word condition. These findings suggest that it is the neural "context" of the VWFA, i.e., the broader activity distributed in the brain that is correlated with VWFA, that is specific for visual word representation, not activity in this brain region per se. 相似文献

ABSTRACT— Childhood-onset antisocial behavior is an important predictor of chronic and serious forms of antisocial behavior in later life. Both biological and social factors are involved in the development of abnormal behavior. We examine the underlying role of stress-response systems in the link between early social adversity and juvenile antisocial behavior, and propose that children with genetically and/or perinatally based neurobiological deficits have problems in activating these systems and therefore experience difficulties in regulating affect and behavior. Underactivity or attenuated reactivity of the stress-response systems may predispose antisocial individuals to seek out stimulation or take risks, and thereby explain deficits in learning and socialization. Further investigations of neurobiological functioning in antisocial children might not only indicate which children are more likely to persist in behaving antisocially but also guide the development of new interventions. 相似文献

Children often make impulsive choices, and previous research has shown that access to activities during the delay may enhance self‐control (e.g., Newquist, Dozier, & Neidert, 2012). The purpose of the current study was to extend the results of Newquist et al. (2012) by comparing the effects of access to low‐preference, moderate‐preference, and high‐preference toys during delays. Results showed that (a) all toys increased self‐control for 2 participants when toys were available for all choice options and (b) high‐preference toys (and sometimes moderate‐preference toys) increased self‐control for 3 participants when the toys were available only for large delayed choices. 相似文献

Extant research shows that people use retrieval ease, a feeling-based cue, to judge how well they remember life periods. Extending this approach, we investigated the role of retrieval ease in memory judgments for single events. In Experiment 1, participants who were asked to recall many memories of an everyday event (New Year's Eve) rated retrieval as more difficult and judged their memory as worse than did participants asked to recall only a few memories. In Experiment 2, this ease-of-retrieval effect was found to interact with the shocking character of the remembered event: There was no effect when the event was highly shocking (i.e., learning about the attacks of September 11, 2001), whereas an effect was found when the event was experienced as less shocking (due either to increased distance to "9/11" or to the nonshocking nature of the event itself). Memory vividness accounted for additional variance in memory judgments, indicating an independent contribution of content-based cues in judgments of event memories. 相似文献

Previous findings have been equivocal as to whether the postevent misinformation effect on eyewitness memory is reduced by warnings presented after the misinformation (postwarnings). In the present research, social postwarnings, which characterize the postevent source as a low-credibility individual, diminished the misinformation effect in both cued recall and recognition tests. Discrediting the source as being either untrustworthy or incompetent was effective (Experiment 1). Also, postwarned participants rated reality characteristics of their memories more accurately than did participants receiving no or high-credibility information about the postevent source (Experiment 2). A social postwarning yielded the same results as an explicit source-monitoring appeal and led to longer response times for postevent items, relative to a no-warning condition (Experiments 3 and 4). The findings suggest that the reduced misinformation effect was due to more thorough monitoring of memory characteristics by postwarned participants, rather than to a stricter response criterion or to enhanced event memory. 相似文献
