what does response time on a monitor mean
Response time (technology) Response time is the amount of time a pixel in a display takes to change. It is measured in milliseconds (ms). Lower numbers mean faster transitions and therefore fewer visible image artifacts. Display monitors with long response times would create display motion blur around moving objects, making them unacceptable for rapidly moving images. Response times are usually measured from grey-to-grey transitions, but there is no industry standard.[3]
Word frequency effect Most studies looking at the word frequency effect use eye tracking data. When words have a higher frequency, readers fixate on them for shorter amounts of time.[8] In one study, participants' eye movements were recorded as they scanned single sentence stimuli for topic relevant words.[9] Researchers used an Eyelink eye tracker to record the movements of the participants' eyes. Reading times were found to be longer when focusing for comprehension due to increased average fixation durations. Results showed that reading for comprehension rather than scanning for certain words took longer fixations on the text.[9]
