大量研究表明,复习对正确记忆和虚假记忆有不同影响。对于正确记忆,保持量随学习次数的增加而增加,但对于虚假记忆,目前的研究结论并不一致。该文综述了近年来关于复习对正确记忆和虚假记忆不同影响的研究,并介绍了内隐激活反应假设和模糊痕迹理论对这一问题的解释 相似文献

条件性味觉厌恶分化后臂旁核c-fos表达的变 总被引:1,自引:0,他引:1
以口内注入糖精或蔗糖溶液为条件刺激,腹腔内注射LiCl为非条件刺激,在大鼠形成条件性味觉厌恶后进行分化训练,观察味质和嗜好性对臂旁核各亚核c-fos表达的影响及其交互作用。结果表明:味质和嗜好性对背侧外侧亚核(dls)和腹侧外侧亚核(vls)的c-fos表达无影响;在内侧外侧亚核(ils)和外部内侧亚核(ems),蔗糖诱导的c-fos表达高于糖精,但在外部外侧亚核(els),糖精诱导的表达高于蔗糖;嗜好性刺激引起ils、中央外侧亚核(cls)和cms内c-fos高表达,厌恶性刺激引起ems和els内的高表达。在ils和cms嗜好性与味质的影响各自独立,在els和ems内嗜好性与味质的影响存在交互作用。提示PBN内存在味质辨别和报酬评价的代表区,两种代表区有交迭,ems和els对味质信息和报酬信息的整合有重要作用 相似文献

Patients with unilateral neglect have problems reporting, responding, or orienting to novel or meaningful stimuli that is presented to the side opposite to that of a brain lesion. This creates a serous problem in regards to daily living activities. However, the established methods for assessing and training of unilateral neglect patients have several deficits. Recently, virtual reality (VR) technologies have been used as an assessment and treatment tool for rehabilitation. Hence, this study designed a VR system to assess and train unilateral neglect patients. In addition, the suitability and feasibility of our VR system for unilateral neglect patients was verified. 相似文献

In this research, the effectiveness of neurofeedback, along with virtual reality (VR), in reducing the level of inattention and impulsiveness was investigated. Twenty-eight male participants, aged 14-18, with social problems, took part in this study. They were separated into three groups: a control group, a VR group, and a non-VR group. The VR and non-VR groups underwent eight sessions of neurofeedback training over 2 weeks, while the control group just waited during the same period. The VR group used a head-mounted display (HMD) and a head tracker, which let them look around the virtual world. Conversely, the non-VR group used only a computer monitor with a fixed viewpoint. All participants performed a continuous performance task (CPT) before and after the complete training session. The results showed that both the VR and non-VR groups achieved better scores in the CPT after the training session, while the control group showed no significant difference. Compared with the other groups, the VR group presented a tendency to get better results, suggesting that immersive VR is applicable to neurofeedback for the rehabilitation of inattention and impulsiveness. 相似文献

Five adults with profound physical and intellectual disabilities were taught to respond to photographs of preferences embedded in Microsoft PowerPoint (Microsoft, 1997 ) presentations by operating microswitches that functioned as mouse clicks. Rate of responding was generally correlated with changes in types of presentation, although variability in rate was often high, and session durations were quite short. Two participants showed substantial increases in responding when fitted with switches that were easier to manipulate. This exploratory study demonstrates that people with extremely limited physical and cognitive abilities can be taught to operate switches that produce changes in visual arrays on a computer screen and sometimes differentially so. Implications for responding to photographic representations of preferences, rather than the tangible preferences themselves, are discussed. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献
