“…The result that skilled players had shorter saccade latency than less skilled players suggests that skilled players had faster information processing speed than less skilled players. This is consistent with previous studies, demonstrating that saccade latency is influenced by information processing speed ( Noiret et al, 2017 , 2018 ) and others showing that saccade latency varies as a function of cognitive function ( Coors et al, 2021 ; Thomas et al, 2021 ). More importantly, this result is also consistent with studies, demonstrating that players’ cognitive capacities vary as a function of their skill levels ( Vestberg et al, 2012 , 2017 ; Glavaš, 2020 ).…”

“…They are popular because eye movement measures are easy to obtain and participants can understand eye movement tasks easily ( Noiret et al, 2017 ). More importantly, eye-tracking methods provide unique means to measure cognitive processes ( Thomas et al, 2021 ). Therefore, eye movement experiments are carried out in different populations in various research domains ( Noiret et al, 2018 ).…”

Although the relationship between cognitive processes and saccadic eye movements has been outlined, the relationship between specific cognitive processes underlying saccadic eye movements and skill level of soccer players remains unclear. Present study used the prosaccade task as a tool to investigate the difference in saccadic eye movements in skilled and less skilled Chinese female adolescent soccer players. Fifty-six healthy female adolescent soccer players (range: 14–18years, mean age: 16.5years) from Fujian Youth Football Training Base (Fujian Province, China) took part in the experiment. In the prosaccade task, participants were instructed to fixate at the cross at the center of the screen as long as the target appeared peripherally. They were told to saccade to the target as quickly and accurately as possible once it appeared. The results indicated that skilled soccer players exhibited shorter saccade latency (p=0.031), decreased variability of saccade latency (p=0.013), and higher spatial accuracy of saccade (p=0.032) than their less skilled counterparts. The shorter saccade latency and decreased variability of saccade latency may imply that the attentional system of skilled soccer player is superior which leads to smaller attention fluctuation and less attentional lapse. Additionally, higher spatial accuracy of saccade may imply potential structural differences in brain underlying saccadic eye movement between skilled and less skilled soccer players. More importantly, the results of the present study demonstrated that soccer players’ cognitive capacities vary as a function of their skill levels. The limitations of the present study and future directions of research were discussed.

“…In sum, no effects of target eccentricity were observed for the latency metric. This is analogous with the existing literature [10,38]. Landgraf and colleagues [26] highlighted an overall group difference in gain control and final eye position; whereby the SZ patients showed reduced abilities when compared to their family members and controls.…”

“…These deficits have been shown to predate the onset of the disease [32,33]. This atypicality has been replicated in psychosis patients [23,24,27,28,34] independent of medication status [28], their full siblings [26], relatives [27,35], and those with high-schizotypy [36][37][38]; supporting its candidacy as an oculomotor endophenotype.…”

Memory-Guided Saccades in Psychosis: Effects of Medication and Stimulus Location

The memory-guided saccade task requires the remembrance of a peripheral target location, whilst inhibiting the urge to make a saccade ahead of an auditory cue. The literature has explored the endophenotypic deficits associated with differences in target laterality, but less is known about target amplitude. The data presented came from Crawford et al. (1995), employing a memory-guided saccade task among neuroleptically medicated and non-medicated patients with schizophrenia (n = 31, n = 12), neuroleptically medicated and non-medicated bipolar affective disorder (n = 12, n = 17), and neurotypical controls (n = 30). The current analyses explore the relationships between memory-guided saccades toward targets with different eccentricities (7.5° and 15°), the discernible behaviour exhibited amongst diagnostic groups, and cohorts distinguished based on psychotic symptomatology. Saccade gain control and final eye position were reduced among medicated-schizophrenia patients. These metrics were reduced further among targets with greater amplitudes (15°), indicating greater deficit. The medicated cohort exhibited reduced gain control and final eye positions in both amplitudes compared to the non-medicated cohort, with deficits markedly observed for the furthest targets. No group differences in symptomatology (positive and negative) were reported, however, a greater deficit was observed toward the larger amplitude. This suggests that within the memory-guided saccade paradigm, diagnostic classification is more prominent in characterising disparities in saccade performance than symptomatology.

“…In medicine, particularly in clinical practice, eye tracking has been used for skill training for procedures, such as laparoscopy, where training gaze behavior significantly improves medical trainees' performance [21] . Eye tracking has also been used to train surgery residents [6] and radiologists [20] , among others [1] , and is also broadly used as a research tool to support clinical diagnosis and training [ 5 , 10 , 18 , 19 ]. In industry, eye-tracking applications range from evaluating web advertising efficacy [15] to driving optimization [9] .…”
