dc.description.abstractThe technological barriers to new methods of vision testing are continuously being eroded. As instrumentation becomes more accessible and user friendly, methods that were previously only available in select research laboratories become more practical for broader experimenta- tion and eventual clinical application. To further examine complex visuo-motor phenomena (e.g. coincidence anticipation timing under glaring conditions) instruments capable of per- forming six psychophysical tests (coincidence anticipation timing, reaction timing with fixed and variable target locations, flicker fusion testing, glare disability testing, and photostress recovery timing) were constructed and 12 subjects were tested on all six tasks at two testing sessions. Test-retest reliability was generally high (r > 0.8, p < 0.05) and all tests had eco- logical validity. These experiments demonstrate that complex laboratory experiments can be performed with practical equipment while still retaining high experimental standards.
