Sequential visual reaction times
1988
The reaction-time to a series of successive digits was measured on two subjects. After practice, it was found that whilst the reaction time to the onset of the series was constant at 150 ms, the response time to additional digits became less and less to asymptote to a level of about 50 ms. The time course of this ‘chorus-line’ phenomenon was studied in greater temporal detail by varying the interval in steps of 20 ms. The effect was greatest at 200 ms. Thereafter, it declined and for long intervals reached the value of a standard reaction time. On a third inexperienced subject, the learning period was established; this was about 300–400 presentations. The implications of these findings are …
Evaluation of visual-motor reaction time and quality of response in rugby sevens players after the application of a neurocognitive training programme
2019
This work proposes a neurocognitive training (NCT) programme that seeks to optimise the mechanisms of visual perception, the processing of information and decision making. Also, to evaluate the eff...
Visual search in three-dimensional non-medical images: visual-motor performance of radiologists
2019
The visual search abilities of radiologists are systematically trained due to the specifics of their professional tasks. We investigated whether the visual-motor performance of radiologists, residents and students varied when searching non-medical targets on the volumetric display. As a result, no significant differences were found in the correct response rate among three groups. However, the total number of interactions was considerably higher for the resident radiologists and medical students comparing to the experienced radiologists. Our results suggest that the radiological experience does not interfere with the outcome in the developed visual search task, but may be reflected in motor …
