A study by Roder, Bushnell, and Sassville that used this measure demonstrated how two different preferences compete to affect this measure. This measure was the dependent variable in a study by Kelly et al. that used the other-race effect to demonstrate perceptual narrowing. This measure is recorded for different stimuli in the VPC task. Studies that use (*) habituation as a research technique use the change in this measure as a dependent variable. The change in this quantitative measure was the subject of a pioneering 1964 experiment by R. L. Fantz that introduced the notion of novelty preference. Psychological attention experiments on preverbal infants usually use this measure in studies where subjects are exposed to new fixed images. For 10 points, what temporal measure is measured by tracking the fixity and change in visual focus? ■END■
ANSWER: infant look duration [accept time in place of duration; accept any descriptive answers that mention how long a subject looks at some object; prompt on time; prompt on eye movement; prompt on attention by asking “how is attention measured?”]
