Paulus J, Tong J, Hornegger J, Schmidt M, Eskofier B, Michelson G - Front Psychol (2014)

Bottom Line: The soccer players could not perform significantly (p ≤ 0.05) superior than the subjects without soccer background.However, the soccer players showed significantly (p ≤ 0.01) superior choice reaction times for monocular stimuli.The results are in congruence with previous findings in literature.

ABSTRACT
Stereopsis is one of several visual depth cues. It has been evaluated for athletes of different types of sports in the past. However, most studies do not cover the full range of stereopsis performance. Therefore, we propose computer-supported stereopsis tests that provide an extended assessment and analysis of stereopsis performance including stereo acuity and response times. By providing stationary and moving stimuli they cover static and dynamic stereopsis, respectively. The proposed stereopsis tests were used to compare professional and amateur soccer players with subjects without soccer background. The soccer players could not perform significantly (p ≤ 0.05) superior than the subjects without soccer background. However, the soccer players showed significantly (p ≤ 0.01) superior choice reaction times for monocular stimuli. The results are in congruence with previous findings in literature.

Figure 3: Median of static stereo acuities per group. The median of the amateur group corresponds to the lower bound of the box, the 25th percentile of 30 arcsecs.

Mentions: The number of subjects that were able to recognize a certain disparity difference decreased with decreasing disparity differences in each group (Table 1). The static stereo acuities as assessed by the proposed test did not differ significantly between all groups (Figure 3). Also after excluding the subjects that were not able to recognize any of the presented disparity differences the static stereo acuities did not differ significantly between the groups.
