The aim of this study was to determine whether the type of bilingualism affects neural organisation. We performed identification experiments and mismatch negativity (MMN) registrations in Finnish and Swedish language settings to see, whether behavioural identification and neurophysiological discrimination of vowels depend on the linguistic context, and whether there is a difference between two kinds of bilinguals. The stimuli were two vowels, which differentiate meaning in Finnish, but not in Swedish. The results indicate that Balanced Bilinguals are inconsistent in identification performance, and they have a longer MMN latency. Moreover, their MMN amplitude is context-independent, while Dominant Bilinguals show a larger MMN in the Finnish context. These results indicate that Dominant Bilinguals inhibit the preattentive discrimination of native contrast in a context where the distinction is non-phonemic, but this is not possible for Balanced Bilinguals. This implies that Dominant Bilinguals have separate systems, while Balanced Bilinguals have one inseparable system. 相似文献

General intelligence, the g factor, is a major issue in psychology and neuroscience. However, the neural mechanism of the g factor is still not clear. It is suggested that the g factor should be non-modular (a property across the brain) and show good colinearity with various cognitive tests. This study examines the hypothesis that functional connectivity may be a good candidate for the g factor. We recorded resting state eyes-closed EEG signals in 184 healthy young females. Coherence values of 38 selected channel pairs across delta, theta, alpha, beta and gamma frequencies were correlated with six intelligence quotient (IQ) subtests, including symbol search, block design, object assembly, digit span, similarity and arithmetic. A three-stage analytic flow was constructed to delineate common (g factor) and unique neural components of intelligence. It is noticed that the coherence pattern demonstrates good correlation with five of the IQ subtests (except symbol search) and non-modularity in the brain. Our commonality analyses support connectivity strength in the brain as a good indicator of the g factor. For the digit span and arithmetic tests, the uniqueness analyses provide left-lateralized topography relevant to the operation of working memory. Performance on the arithmetic test is further correlated with strengths at left temporo-parietal and bilateral temporal connections. All the significant correlations are positive, indicating that the stronger the connectivity strengths, the higher the intelligence. Our analyses conclude that a smarter brain is associated with stronger interaction in the central nervous system. The implication and why the symbol search does not show parallel results are discussed. 相似文献

The word any may appear in some sentences, but not in others. For example, any is permitted in sentences that contain the word nobody, as in Nobody ate any fruit. However, in a minimally different context any seems strikingly anomalous: *Everybody ate any fruit. The aim of the present study was to investigate how the brain responds to the word any in such minimally different contexts - where it is permitted (licensed) and where it is not permitted (unlicensed). Brain responses were measured from adult readers using magnetoencephalography (MEG). The results showed significantly larger responses to permissible contexts in the left posterior temporal areas between 400-500 ms and 590-660 ms. These results clarify the anatomy and timing of brain processes that contribute to our judgment that a word such as any is or is not permitted in a given context. 相似文献

In previous studies we have shown that a General Factor of Personality (GFP) occupies the apex of the hierarchy of personality as well as the apex of the personality disorders in the same way that g, the general factor of mental ability, occupies the apex in the organization of cognitive abilities (Rushton & Irwing, 2011). In a critique, Muncer (2011) re-analyzed one of our data sets and concluded there was no evidence for a GFP. He also argued against the evolutionary theory we had proposed for the origin of the GFP. In this rejoinder I rebut Muncer’s conclusion and describe how directional selection can explain the GFP. 相似文献

This article is essentially theoretical and is focused on the allocative function of the legal systems to attract/reject different capitals according to their procedures to shape norms and laws. This function of the legal systems is pivotal in our times as humankind is facing a systemic and evolutionary bifurcation between the heideggerian Gegnet of a strategic, high speed convergence (i.e., Singularity) among robotics, informatics, nanotechnologies, and genetics (RINGs)—which will reshape human life in terms of its life quality styles and standards especially regarding health and environment matters, and the so called Neofeudal Scenario (NS) supported by those for whom the Industrial Model failed and the only way to save humankind and its environment would be a kind return to a Medieval life style based on a slow pace of life and austerity. This article provides an overview of the most important and recent international references regarding the two alternatives of bifurcation and describes a potential paradigm shift inside the systemic approach to reframe the conceptual map of global change through a systemic epistemology of the sociology of law. 相似文献

The primary purpose of our target article was to stimulate further interest in and research on consumer decision-making in close relationships. In this response, we discuss some of the major comments provided by each set of commentators by highlighting their main points, clarifying some misconceptions, and explaining why our dyadic framework is a logical starting-point for research on how relationships affect consumer decisions. 相似文献

The Hautmont tornado has occurred on august 03, 2008, in the North of France. It was caused major destructions in this town and particularly in this city hospital. A tornado is a major natural phenomenon that causes destructions and disasters. In the literature, natural disaster and their destructive consequences are associated with psycho-traumatic disorders, among which is posttraumatic stress. The purpose of this research was to study the psychological impact of this tornado on a particularly vulnerable population: employees of a hospital. Thirty eight employees were interviewed one year after the Tornado. The results of this study showed that this disaster had many psychological repercussions. Many cases of posttraumatic stress disorders and cases of burnout were present independently of job strain level. 相似文献

Research suggests a central role of executive functions for children's cognitive and social development during preschool years, especially in promoting school readiness. Interventions aiming to improve executive functions are therefore being called for. The present study examined the effect of a small group intervention implemented in kindergarten settings focusing on basic components of executive functions, i.e., working memory, interference control and cognitive flexibility. A total of 135 children enrolled in Swiss prekindergarten (5‐year‐olds) and kindergarten (6‐year‐olds) were involved. Results revealed that the small group intervention promoted gains in all three included components of executive functions: prekindergarten children substantially improved their working memory and cognitive flexibility processes, whereas significant training effects were found for the kindergarten children in interference control. Implications of these findings for early intervention programs and for tailoring preschool curricula are discussed, particularly with respect to children's school readiness.

在许多社会科学研究中,社会称许性会对研究的效度产生不良影响。研究者希望能得到被试的真实态度和反应,从而极力避免这种社会称许性偏见。内隐测量工具的一个主要目的是让研究者能够获得未加任何粉饰的态度测量结果从而消除和避免自我表现和社会称许性。本文通过四个实验考察了内隐联想测验的可掩饰性、掩饰的持久性、掩饰的条件化和IAT经验的迁移性,结果显示:(1)被试可以通过一定的反应策略来掩饰其真实的内隐态度,从而使所测得的个体内隐态度和群体内隐态度失真,典型的反应策略是均衡相容和不相容任务的反应速度;(2)内隐联想测验的可掩饰性需以先前的IAT经验为基础,且IAT经验无需属于相同的测验范畴,对IAT原理的掌握将有助于被试成功地实施掩饰;(3)内隐联想测验的可掩饰性具有一定的时效性,先前的IAT经验越久远,则成功掩饰的可能性越低;总之,内隐联想测验并不能彻底避免社会称许性。 相似文献

Abstract This paper presents a discussion of the previously unpublished correspondence between Stekel and Freud. The authors start with a brief overview of most important historic events and facts that constitute the context against which these letters should be read. The matters cover questions of publishing policy, personal priorities, and psychoanalytic principles. The authors suggest that the Stekel letters may have been preserved by Freud as evidence of the latter's estrangement from him, as tokens of betrayal. A minute discussion of the correspondence makes it possible to discuss day-to-day developments in this fateful relation, taking into account Stekel's side of the story for the first time as well, highlighting the backfiring of a strategic maneuver by Stekel to psychoanalyse the Freud family, which heralded his downfall, and also revealing the role that Victor Tausk played in this. The paper concludes with a discussion of the dialectics of estrangement. 相似文献
