Figure 2
Measures of head movement (a) and of cognition (b). To facilitate comparisons, raw scores were transformed into percentages of young subjects’ means. The means of older subjects are depicted by black blocks, and those of young subjects (i.e., 100%) by gray blocks. Error bars represent the standard errors ***indicates , *indicates , and n.s. indicates no significance. Note that “executive function” and “psychomotor speed” are time based parameters such that lower scores indicate better performance.
