A Timely Reminder About Stimulus Display Times and Other Presentation Parameters on CRTs and Newer Technologies.
Scientific experimentation requires specification and control of independent variables with accurate measurement of dependent variables. In Vision Sciences (here broadly including experimental psychology, cognitive neuroscience, psychophysics, and clinical vision), proper specification and control o...

In Vision Sciences (here broadly including experimental psychology, cognitive neuroscience, psychophysics, and clinical vision), proper specification and control of stimulus rendering (already a thorny issue) may become more problematic as several newer display technologies replace cathode ray tubes (CRTs) in the lab. The present paper alerts researchers to spatiotemporal differences in display technologies and how these might affect various types of experiments. Parallels are drawn to similar challenges and solutions that arose during the change from cabinet-style tachistoscopes to computer driven CRT tachistoscopes. Technical papers outlining various strengths and limitations of several classes of display devices are introduced as a resource for the reader wanting to select appropriate displays for different presentation requirements. These papers emphasise the need to measure rather than assume display characteristics because manufacturers' specifications and software reports/settings may not correspond with actual performance. This is consistent with the call by several Vision Science and Psychological Science bodies to increase replications and increase detail in Method sections. Finally, several recent tachistoscope-based experiments, which focused on the same question but were implemented with different technologies, are compared for illustrative purposes. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: N holdings: @attributes: islocal: N |
