“…It is interesting to note that there is some evidence of impairment in AD and MCI on tasks requiring information integration (Festa et al, 2005; Foster, Behrmann, & Stuss, 1999; Golob, Miranda, Johnson, & Starr, 2001). Some groups, including ours, are beginning to investigate cortical connectivity and its relation to cognitive functioning in MCI (e.g., Jiang & Zheng, 2006; Johns, Davies, & Phillips, 2011; Pijnenburg et al, 2004), but more work is needed in this area.…”

Amnestic mild cognitive impairment (aMCI) represents a group of individuals who are highly likely to develop Alzheimer's disease (AD). Although aMCI is typically conceptualized as involving predominantly deficits in episodic memory, recent studies have demonstrated that deficits in executive functioning may also be present, and thorough categorization of cognitive functioning in MCI may improve early diagnosis and treatment of AD. We first provide an extensive review of neuropsychology studies that examined executive functioning in MCI. We then present data on executive functioning across multiple sub-domains (divided attention, working memory, inhibitory control, verbal fluency, and planning) in 40 aMCI patients (single or multiple domain) and 32 normal elderly controls (NECs). MCI patients performed significantly worse than NECs in all 5 sub-domains, and there was impairment (>1.0 SD below the mean of NECs) in all sub-domains. Impairment on each test was frequent, with 100% of MCI patients exhibiting a deficit in at least one sub-domain of executive functioning. Inhibitory control was the most frequently and severely impaired. These results indicate that executive dysfunction in multiple sub-domains is common in aMCI and highlights the importance of a comprehensive neuropsychological evaluation for fully characterizing the nature and extent of cognitive deficits in MCI.

“…Through the research in this section, it is found that the special decision-making abilities of highperformance professional tennis players cannot be transferred to daily life. (Johns et al, 2011;Buchanan and Barrow, 2016). During a tennis teaching match, there are many factors that can affect the decisions of tennis players, involving not only the processing of the physical characteristics of stimulus information, but also the endogenous cognitive processing.…”

Tennis is a skill-oriented antagonistic net-separating sport. It requires players to change speed and give responses very quickly and make accurate judgments and decisions on the path of the ball. Based on electroencephalography (EEG), this paper assigns general-situation and specific-situation decision making tasks to tennis players and college students, and analyzes the cognitive mechanisms of tennis players. The experimental results show that: college students' decision-making response time was obviously longer than that of the player group, and that the decision scores and accuracy of the player group were significantly higher than those of the college student group. After specialized training, tennis players had intuitions when making decisions. Their intuitive decision-making abilities were much stronger than those of the college student group. Due to the spatial positioning or stimulatory interference suppression effects of the players' brains, stimulus conditions induced P1 and P2 waveforms, and with the peak amplitude increasing and the latency period becoming longer, such phenomena of the player group were increasingly obvious.
