“…This type of design allowed for the parsing of the within-and betweenperson variance in occasion reading vision, in addition to the coupling relationship between reading vision and cognitive performance. Although previous research examining intraindividual variability in vision is limited, the results are similar to what has been found in the literature (e.g., Abbud & Cruz, 2002;Fisher & Carr, 1970). Specifically, we observed that a substantial amount of variability in occasion reading vision is due to the within-person variation.…”

“…For instance, Fisher and Carr (1970) found significant day-to-day variability in night vision in young and middle aged men. One other study administered, on average, 500 assessments of visual acuity, during one testing session (Abbud & Cruz, 2002).…”

“…It is also possible that a one time assessment of vision might not be very reliable. In fact research has shown that vision does fluctuate over relatively short periods of time (Abbud & Cruz, 2002;Fisher & Carr, 1970).…”

This study examined the within-person relationship between reading vision and cognitive functioning. Analysis was conducted on 36 community-dwelling elderly (age range = 60-87) who completed a reading vision task and three cognitive tests (i.e., Rey Auditory Verbal Learning Task (AVLT), Letter Series, and Number Comparison) twice a day over 60 consecutive days. Significant within-person variability was found for the reading vision measure. Additionally, a main effect was found for reading vision and performance on the AVLT and Number Comparison task; such that on occasions when reading vision was poor, cognitive performance suffered.

“…A previous report on individual variability in dark adaptation and night vision in man reviewed studies through 1970 (Fisher and Carr, 1970). A more recent report emphasized the biological differences between men in their scotopic visual ability and enumerated several areas of research that might be pursued within the broad concept of biological individuality as related to an individual's performance in a military environment (Carr eta!., 1974).…”

“…Any environmental situation that produced hypoxia will adversely influence night vision in all subjects and this phenomenon has been studied extensively (Fisher et al, 1970). Vestibular stimulation associated wi+h motion and the accompanying nystagmus have also been shown to adversely influence pilots aUlity to read cockpit instruments under low levels of illumination (Gilson et al, 1970).…”

It can be remarkably difficult to determine whether two photographs of unfamiliar faces depict the same person or two different people. This fallibility is well established in the face perception and eyewitness domain, but most of this research has focused on the "average" observer by measuring mean performance across groups of participants. This study deviated from this convention to provide a detailed description of individual differences and observer consistency in unfamiliar face identification by assessing performance repeatedly, across a 3-day (Experiment 1) and a 5-day period (Experiment 2). Both experiments reveal considerable variation between but also within observers. This variation is such that the same observers frequently made different identification decisions to the same faces on different days (Experiment 1). And when new faces were shown on each day, observers that produced perfect accuracy on one day made many misidentifications on another (Experiment 2). However, a few individuals also performed with consistent high accuracy in these tests. These findings suggest that accuracy and consistency are separable indices of face-matching ability, and both measures are necessary to provide a precise index of a person's face processing skill. We discuss whether these measures could provide the basis for a selection tool for occupations that depend on accurate person identification.
