Effects of word predictability and preview lexicality on eye movements during reading: A comparison between young and older adults.

Research with lexical neighbours (words that differ by a single letter while the number and order of letters are preserved) indicates that readers frequently misperceive a word as its higher frequency neighbour (HFN) even during normal reading. But how this lexical influence on word identification changes across the adult lifespan is largely unknown, although slower lexical processing and reduced visual abilities in later adulthood may lead to an increased incidence of word misperception errors. In particular, older adults may be more likely than younger adults to misidentify a word as its HFN, especially when the HFN is congruent with prior sentence context, although this has not been investigated. Accordingly, to address this issue, young and older adults read sentences containing target words with and without an HFN, where the HFN was either congruent with prior sentence context or not. Consistent with previous findings for young adults, eye movements were disrupted more for words with than without an HFN, especially when the HFN was congruent with prior context. Crucially, however, there was no indication of an adult age difference in this word misperception effect. We discuss these findings in relation to the nature of misperception effects in older age.

Eye Movements During Reading

Abstract. We report the results of a meta-analysis of 22 experiments comparing the eye movement data obtained from young ( Mage = 21 years) and old ( Mage = 73 years) readers. The data included six eye movement measures (mean gaze duration, mean fixation duration, total sentence reading time, mean number of fixations, mean number of regressions, and mean length of progressive saccade eye movements). Estimates were obtained of the typified mean difference, d, between the age groups in all six measures. The results showed positive combined effect size estimates in favor of the young adult group (between 0.54 and 3.66 in all measures), although the difference for the mean number of fixations was not significant. Young adults make in a systematic way, shorter gazes, fewer regressions, and shorter saccadic movements during reading than older adults, and they also read faster. The meta-analysis results confirm statistically the most common patterns observed in previous research; therefore, eye movements seem to be a useful tool to measure behavioral changes due to the aging process. Moreover, these results do not allow us to discard either of the two main hypotheses assessed for explaining the observed aging effects, namely neural degenerative problems and the adoption of compensatory strategies.
