Abstract： Mind sports are competitive sports that aim at developing intelligence and involves multiple high-level cognitive processing. Deliberate practice enables the mind sports experts to exhibit steady expertise effects in domain-specific tasks. A review of previous research reveals that perception and memory are not only the basis of high-level cognitive functions, but also the central to the mind sports expert advantage. That is, the extraordinary performance of the mind sports experts is based on their perceptual and memory advantage. In this paper, we summarize the cognitive neural mechanisms through which expert perception and memory are influenced by the experience of mind sports from the perspective of cognitive neuropsychology to reveal the intrinsic processing patterns and neural mechanisms of the expertise effects in mind sports. Long-term training contributed to a stable holistic perceptual advantage in mind sports experts, as reflected by the fact that experts made a greater proportion of fixations between the pieces and completed the perceptual task with fewer fixations. This performance is consistent with the holistic model of image perception, in which the experts automatically process information about the entire game or board with a larger perceptual span, quickly locate task-relevant target areas with prior knowledge, and process abstract pieces relations in parallel. The temporo-parietal junction and fusiform gyri are the neural bases of a holistic perceptual process. Mind sports experts also have a stable memory advantage. Long-term training in mind sports allows experts to store not only a large amount of visual-spatial information in their long-term memory, but also more abstract and generalized knowledge. The Chunking and Template theory argues that experts rely primarily on concrete visuospatial information and therefore have an advantage when processing familiar stimuli. To explain experts' advantage in memorizing random chess stimuli, the SEEK theory suggests that experts have rich and flexible abstract knowledge and therefore have a memory advantage even when processing unfamiliar or stimuli that change presentation. The neural basis for the expert's advantage in accurate, rapid, and flexible memory is the synergistic activity of the medial temporal, frontotemporal, and frontoparietal regions. The existence of stable superior performance of experts in mind sports on tasks within the domain suggests that deliberate practice can improve experts' specific skills, supporting the view that training can promote intelligence. The following shortcomings still exist: 1) most studies have mainly focused on the chess domain, and it is still unclear whether the differences in cognitive demands of different mind sports lead to differences in extrinsic behavior and intrinsic neural basis; 2) existing studies have mainly examined the neural mechanisms underlying mind sports experts' advantage effects through univariate analysis based on voxels. Multi-voxel pattern analysis and representational similarity analysis can be used to explore the intrinsic neural basis more profoundly; 3) The timing of stimulus presentation has not been standardized and the adequacy of timing may lead to a decrease in group differentiation and a mix of other cognitive components. Multimodal studies can be conducted with high temporal resolution EEG and eye-movement recording to explore the dynamic cognitive neural mechanisms in depth. 4) due to a lack of long-term longitudinal study on how novices would become mind sports experts through deliberate practice, it remains incomplete regarding the cognitive performance and the trajectory of neural mechanism changes of mind sports experts. Future research can examine types of mind sports, innovative experimental paradigms, combined with measurement equipment and cognitive characteristics, to explore in depth and detail the neural mechanisms underlying the holistic perceptual advantage and memory advantage of mind sports experts, to provide a theoretical basis for artificial intelligence and skill training.

Abstract： In alphabetic writing systems (such as English), the spaces between words mark the word boundaries, and the basic unit of reading is distinguished during visual-level processing. The visual-level information of word boundaries facilitates reading. Chinese is an ideographic language whose text contains no intrinsic inter-word spaces as the marker of word boundaries. Previous studies have shown that the basic processing unit of Chinese reading is also a word. However, findings remain inconsistent regarding whether inserting spaces between words in Chinese text promotes reading performance. Researchers have proposed that there may be a trade-off between text familiarity and the facilitation effect of inter-word spaces. The purpose of Experiment 1 was to examine whether there was trade-off between text familiarity and facilitation of inter-word spaces. Before reading training, Experiment 1 was conducted that 40 native Chinese undergraduates read Chinese sentences from right to left on four text conditions. The results showed faster reading speed and shorter total reading time for the inter-word spaced text. Based on this finding, 40 native Chinese undergraduates who did not participate in the first stage read Chinese sentences from right to left on four text conditions after ten-day reading training, then, the eye tracking data of participants during Chinese reading were recorded in Experiment 1. Experiment 1 verified there was trade-off between text familiarity and inter-word spaces’ facilitation in Chinese, then, the Experiment 2 examined the role of text familiarity and word frequency in vocabulary recognition. Forty students read Chinese sentences under familiar (from left to right) and unfamiliar (from right to left) texts. The target words were high frequency or low frequency. Using Eyelink 1000, the eye tracking data of 32 undergraduates during Chinese reading were recorded in Experiment 2. Second, right-to-left reading training was conducted over 10 days to improve right-to-left reading experience. Then, the eye tracking data of participants during Chinese reading were recorded in Experiment 2. The results in Experiment 1 showed that: (1) Before training, there was significant different between the total reading time and reading speed under unfamiliarity text, which were shorter reading time and faster reading speed in the inter-word spaced text. (2) After training, there was no significant difference between the total reading time and reading speed in the inter-word spaced text and unspaced text, which suggests that the facilitation effect of inter-word spaces in Chinese reading changed smaller. The results in Experiment 2 showed that: (1) The effect of text familiarity was significant. The fixated time was shorter, and the skipping rate was higher under the familiar text. (2) The main effect of word frequency was significant. Low-frequency words had longer fixation times and a higher skipping rate. (3) Right-to-left training improves reading performance from right to left. (4) The early indexes showed a significant interaction between text familiarity and word frequency. A word-frequency effect occurred under the familiar but not under the unfamiliar texts. The late indexes showed that the interaction between text familiarity and word-frequency was not significant. Results in experiment 1 suggested that there was trade-off between text familiarity and the facilitation of inter-word spaces, which supported the assumption in previous studies. In addition, results in experiment 2 showed the text familiarity may affect the early processing in vocabulary recognition. Based on the Chinese integrated reading model, the word segmentation and vocabulary recognition are unified processing. The E-Z reader model holds the opposite point. Combine the experiment 1 and experiment 2, research showed that word segmentation and vocabulary recognition may be sequential processing in Chinese reading, which provided empirical evidence for Chinese E-Z reader model rather than Chinese integrated model.

Abstract： 研究探讨汉语读者选择眼跳目标时, 中央凹注视词的加工负荷是否影响副中央凹获取信息量, 进而调节随后的眼跳长度。采用眼动追踪技术, 操纵了中央凹注视词的词频(高频、低频)和副中央凹词的笔画数(多笔画、少笔画)。结果发现：从中央凹词到副中央凹少笔画词的眼跳长度显著地长于到多笔画词的, 且这种笔画数效应并不受中央凹加工负荷的调节; 从高频中央凹词到副中央凹词的眼跳长度显著地长于低频词的。在本实验条件下结果提示：中央凹加工负荷在眼跳目标选择中的作用不是通过调节副中央凹获取信息量的多少来实现的。
