An important aspect of human individual face recognition is the ability to discriminate unfamiliar individual. Since many general processes contribute to explicit behavioural performance in individual face discrimination tasks, isolating a measure of unfamiliar individual face discrimination ability in humans is challenging. In recent years, a fast periodic visual stimulation approach (FPVS) has provided objective (frequency-locked) implicit electrophysiological indices of individual face discrimination that are highly sensitive at the individual level within a few minutes of testing. Here we evaluate the test-retest reliability of this response across scalp electroencephalographic (EEG) recording sessions separated by more than two months, in the same 30 individuals. We found no test-retest difference overall across sessions in terms of amplitude and spatial distribution of the EEG individual face discrimination response. Moreover, with only 4 stimulation sequences corresponding to 4 min of recordings per session, the individual face discrimination response was highly reliable in terms of amplitude, spatial distribution, and shape. Together with previous observations, these results strengthen the diagnostic value of FPVS-EEG as an objective and rapid flag for specific difficulties at individual face recognition in the human population. 相似文献

Substantial work has demonstrated that early nutrition and home environments, including the degree to which children receive cognitive stimulation and emotional support from parents, play a profound role in influencing early childhood development. Yet, less work has documented the joint influences of parenting and nutritional status on child development among children in the preschool years living in low‐income countries. Using panel data from 2016 to 2017 on the parenting, nutritional status, and early developmental outcomes (executive function, language, early numeracy, and socioemotional problems) of 6,508 Cambodian children ages 3–5 years, our findings demonstrate that inequities in early development associated with family wealth are evident at age 3 and increase among children ages 4 and 5 years. Using hierarchical regression analysis, a significant share of these inequalities is explained by differences in parenting and early nutritional status, measured by stunting. Better‐educated parents engage in more stimulating and supportive parenting practices. However, the positive association between parenting and language and early numeracy outcomes is 35–54% stronger for non‐stunted children, and parental activities explain only about 8–14% of the cognitive gap between the lowest and highest wealth quintiles. The results highlight the need for additional research outlining interactions between environmental factors that link family wealth and child development. 相似文献

We propose quantitative experimental approaches to the question of whether positive and negative reinforcement are functionally different, and discuss scientific and ethical concerns that would arise if these approaches were pursued. 相似文献

In the context of forensic psychiatry, it is crucial that diagnoses of deviant sexual interests are resistant to manipulation. In a first attempt to promote the development of such tools, the current fMRI study focusses on the examination of hemodynamic responses to preferred, in contrast to non-preferred, sexual stimuli with and without explicit sexual features in 24 healthy heterosexual subjects. The subliminal stimulus presentation of sexual stimuli could be a new approach to reduce vulnerability to manipulation. Meaningful images and scrambled images were applied as masks. Recognition performance was low, but interestingly, sexual preference and explicitness modulated stimulus visibility, suggesting interactions between networks of sexual arousal and consciousness. With scrambled masks, higher activations for sexually preferred images and for explicit images were found in areas associated with sexual arousal (Stoleru, Fonteille, Cornelis, Joyal, & Moulier, 2012). We conclude that masked sexual stimuli can evoke activations in areas associated with supraliminal induced sexual arousal. 相似文献

通过干预范式和中介刺激法,选择89名初中一年级学生为被试,采用一系列自编的材料和工具,初步探讨了关键字母法对英文词汇记忆效能的制约因素.结果表明:(1)无论从短期看,还是从长期看.难以识别关键字母,会在一定程度上制约关键字母法的效能,不过,该因素的制约作用并不显著;(2)无论从短期看.还是从长期看,无论为准确的回忆,还是为大致的回忆,难以提取关键字母释义是制约关键字母法的显著因素.中介刺激法,作为本研究的突出特征,试图继承和发展维果茨基所创立的双莺刺激法. 相似文献

Self-enhancement is the biasing of one’s view of oneself in a positive direction. The brain correlates of self-enhancement remain unclear though it has been reported that the medial prefrontal cortex (MPFC) may be important for producing self-enhancing responses. Previous studies have not examined whether the neural correlates of self-enhancement depend on the particular domain in which individuals are enhancing themselves. Both moralistic and egoistic words were presented to participants while transcranial magnetic stimulation (TMS) was applied to the MPFC, precuneus or in a sham orientation. Participants were asked to make decisions as to the words describing themselves, some of which were positive and some of which were negative. It was found the MPFC TMS significantly disrupted egoistic self-enhancement when TMS was delivered to the MPFC. Judgments involving moralistic words were not influenced by TMS. These data provide further evidence that MPFC is involved in self-enhancement, and that the role of MPFC may be selective in this regard. 相似文献

道德直觉加工机制的理论构想 总被引:1,自引:0,他引:1
认知和情绪因素在道德判断中的作用机制是社会认知神经科学研究中最具争议的热点问题之一。本文认为, 人类拥有一种普遍性的道德直觉, 它是一种可能同时包含道德知识和情绪情感的自动化加工系统, 决定人们对一个道德违反情境作出快速的判断。据此, 本文就如何深入揭示道德直觉的加工机制提出了研究构想, 研究将首先采用经颅磁刺激技术, 探索当认知功能受抑制后人们的道德加工的特点, 初步探索道德直觉存在的可能性; 然后采用事件相关电位技术, 从外显和内隐两个维度上探讨道德直觉的时程加工机制; 最后采用侧向化运动准备电位指标, 进一步探索道德直觉和基本厌恶情绪的分离。 相似文献

The effects of preferred stimulation on the vocal stereotypy of 2 individuals were evaluated in two experiments. The results of Experiment 1 showed that (a) the vocal stereotypy of both participants persisted in the absence of social consequences, (b) 1 participant manipulated toys that did and did not produce auditory stimulation, but only sound-producing toys decreased his vocal stereotypy, and (c) only noncontingent music decreased vocal stereotypy for the other participant, but sterotypy paradoxically increased when toys were presented with music. Using a three-component multiple schedule, the results of Experiment 2 showed that the vocal stereotypy of both participants remained below preintervention levels following the removal of auditory stimulation and that 1 participant's vocal stereotypy increased following the removal of contingent reprimands. These patterns suggest that auditory stimulation functioned as an abolishing operation for vocal stereotypy and reprimands functioned as an establishing operation for vocal stereotypy. Together, the two experiments provide a method for identifying alternative stimulation that may substitute for automatically reinforced behavior. 相似文献

One challenge in dominant hemisphere epilepsy surgery is to remove sufficient epileptogenic tissue to achieve seizure freedom
without compromising postoperative language function. Electrical stimulation mapping (ESM) of language was developed specifically
to identify essential language cortex in pharmacologically intractable epilepsy patients undergoing left hemisphere resection
of epileptogenic cortex. Surprisingly, the procedure remains unstandardized, and limited data support its clinical validity.
Nevertheless, ESM for language mapping has likely minimized postoperative language decline in numerous patients, and has generated
a wealth of data elucidating brain–language relations. This article reviews the literature on topographical patterns of language
organization inferred from ESM, and the influence of patient characteristics on these patterns, including baseline ability
level, age, gender, pathology, degree of language lateralization and bilingualism. Questions regarding clinical validity and
limitations of ESM are discussed. Finally, recommendations for clinical practice are presented, and theoretical questions
regarding ESM and the findings it has generated are considered. 相似文献
