Abstract

The goal of this study was to explore whether subjects who successfully completed a web-based computerized, eye movement and reading efficiency training program would retain their improved visual efficiency skills over time. Subjects for this investigation were drawn from the intervention groups of an earlier study by Bragg et al., assessing the effectiveness of the Taylor Associates PANE computerized eye movement efficiency and reading enhancement program. Subjects in the Bragg et. al. intervention groups trained either 2 times per week or 4 times per week for 1 0-weeks using the P AJVE and Reading Plus™ program. Based upon Visagraph II results, both the 2 times per week and 4 times per week training groups demonstrated significantly improved eye movement efficiency immediately following intervention. For this follow up investigation, a subset of twenty non reading-disabled subjects were recruited from the Bragg et. al. study for repeated Visagraph II measurement over time without the benefit of additional training. Our longitudinal study found that improvements in reading eye movement efficiency achieved immediately post-intervention were retained both after 10-weeks and 68-weeks post-intervention. Compared to pre-intervention, post-intervention mean fixations, regressions, reading rate, and relative efficiency scores were significantly better at both 1 0-weeks and 68-weeks, than before training. Although there was a skills regression trend at 68-weeks (slightly greater for 4 times per week training subjects), this decline did not achieve significance relative to pre-training, or even relative to the 10-weeks post-intervention results. Based upon the results of this longitudinal investigation, it appears that eye movement efficiency improvement secondary to P A/VE training is retained for at least one year following training. This study together with the Bragg et. al. , study support the notion that the home-based computerized P A/VE training developed by Taylor and Associates can serve as a valuable tool for improving reading eye movements with non-reading disabled adults and that improvement are maintained for at least one year.
