Eye chart smaller towards the bottom of the chart. The person removes any glasses or contact lenses, and stands or sits a standardized distance from the chart (e.g., 20 feet for the Snellen chart). The person is then asked to identify the optotypes on the chart, starting with large rows and continuing to smaller rows until the optotypes cannot be reliably identified any more. The row in which the person can reliably identify symbols defines the visual acuity. One eye is tested at a time. Practically, this is accomplished by covering the other eye with a hand, piece of paper, or a
Name-letter effect suggests that if the name is liked then the name letters will be liked too. This would occur through repeated visual association of the name letters with the name. Martin and Levey defined evaluative conditioning as a variation of classical conditioning in which we come to like or dislike something through an association. Given the observation that our own name stands out among others as quite an attractive stimulus, as Cherry found in the cocktail party effect, it could be that the name-letter effect results from evaluative conditioning. Feys set up a controlled study with Flemish subjects, pairing unfamiliar symbols
