项目摘要

This study was conducted to examine the development of cognitive and emotional qualia in infants by means of the new brain imaging technique. Our study for the infant's brain imaging showed that the orbitofrontal area in infants has equipped the sensitive function, which is related to cognitive and emotional qualia as same as that of adults.(1) In 2002, we confirmed the applicability of Near-Infrared Spectroscopy (NIRS) and thermography to the brain imaging study for cognitive and emotional responses in infants, and showed that the cognitive and emotional qualia in infants could be measured as the psycho-physiological responses derived by multimodal stimuli, such as mother's face, utterance and touch. For cognitive and emotional qualia in patients with brain damage, the higher executive processing functions of patients were examined by means of the discrimination shift learning. It was showed that the dysfunction for processing elements of stimuli was due to the lesion in frontal area. … More (2) In 2003, the brain activity during processing the visual three dimensional objects was examine by using NIRS. We showed that there are the individual differences of the hemispheric activation, and that the activations in the anterior-parietal area and the fusiform gyrus along changed with viewpoint of perticipants in large task-demand situation. According to this study, the activation on the occipital area in infants was examined under the mother-infant interaction. It was showed that the left hemisphere on the occipital area activated under any personal interactions while the right hemisphere activated only under the infant- unfamiliar person interaction.(3) In 2004, effects of olfactory stimuli, such as braest and articilial milk, on the activation on orbitofrontal area in neonates was examined. We found that the smell of brest milk can mostly activate the frontal area in neonates, and that this was irrespective of feeding conditions. The case study for one infants, who was neglected by parent, showed that his development pf cognitive and emotional qualia could be improved through the intimate personal contact in the nursing home.(4) In 2005, the cognitive and emotional qualia for the facial expression as well as the prosodic features of infant-directed-speech were examined through the brain functional imaging in neonates by NIRS. The longitudinal study for the neonate's brain imaging on the facial expression showed that the cognitive and emotional qualia in infants develop on the frontal brain area by stages. The prosodic feature of mother's utterance could affect the activation on the frontal area in neonates in terms of their qualia development. Less

本研究采用脑成像新技术，对婴儿认知和情绪感受质的发展进行了研究。我们对婴儿的脑显像研究表明，婴儿的眶额区与成人一样具有与认知和情绪感受质有关的敏感功能。(1)2002年，我们证实了近红外光谱（NIRS）和热成像技术在婴儿认知和情绪反应的脑成像研究中的适用性，并表明婴儿的认知和情绪感受质可以被测量为多模态刺激（如母亲的面部、话语和触摸）引起的心理生理反应。对于脑损伤患者的认知和情绪感受质，采用辨别移位学习的方法检测了患者的高级执行加工功能。结果表明，额叶损伤是引起刺激加工要素功能障碍的主要原因。 ...更多信息 (2)2003年，我们用近红外光谱技术研究了视觉三维物体加工过程中的脑活动。结果表明，大脑半球的激活存在个体差异，在大任务需求情境下，前顶区和梭状回的激活沿着随参与者的观点而变化。本研究探讨了在母婴相互作用下婴儿枕区的激活情况。结果表明，枕区左半球在任何人际互动下都激活，而右半球只在婴儿-陌生人互动下激活。(3)2004年，研究了嗅刺激（如母乳和母乳）对新生儿眶额区激活的影响。我们发现，母乳的气味主要可以激活新生儿的额区，这与喂养条件无关。对一名被父母忽视的婴儿的个案研究表明，在护理之家，亲密的个人接触可以促进他的认知和情感素质的发展。(4)2005年，本研究采用近红外光谱技术对新生儿进行了脑功能成像，研究了新生儿面部表情的认知和情感质量以及婴儿引导言语的韵律特征。对新生儿面部表情的脑成像纵向研究表明，婴儿的认知和情绪质在额叶脑区具有阶段性发展。母亲话语的韵律特征可以影响新生儿额区的激活，进而影响其感受质的发育。少
