Lexical priming from partial-word previews.

Two naming and 2 lexical decision experiments examined the use of partial-word previews in visual word recognition. Replicating results of an earlier reading study, the results of Exps 1 and 2 revealed significant benefits from position-specific beginning- and ending-letter previews. Furthermore, benefits from beginning letters were greater for words than for pseudowords. Ending-letter previews showed no corresponding lexical superiority. Exp 3 revealed that preview of position-specific letters from the beginning plus the ending part of target stimuli, which did not reveal a unique word-beginning letter sequence, facilitated the classification of words but not pseudowords. The results support a 2-route model of lexical access in which some partial-word previews afford activation of specific lexical representations, and some partial-word previews afford activation of subword representations.

Integrating information across fixations during reading: The use of orthographic bodies and of exterior letters.

Eye movements were recorded to determine whether the parafoveally visible orthographic body of a bisyllabic target word facilitated recognition during the next target fixation. Eye-movement-contingent display changes revealed part of the target, including its orthographic body, or its beginning letters, when it was parafoveally available, but the full target was visible after it was fixated. Target viewing durations showed no benefit from parafoveal preview of orthographic bodies. Instead, preview benefits derived primarily from the preview of word-initial letters. Examination of oculomotor activity revealed that single target fixations were common when the pretarget word received more than one fixation; conversely, more than one target fixation was common when the pretarget word had received a single fixation. Interword fixation strategies thus affected target viewing, but use of parafoveal target previews was unaffected by these strategies.

Vowel processing during silent reading: Evidence from eye movements.

Two eye movement experiments examined whether skilled readers include vowels in the early phonological representations used in word recognition during silent reading. Target words were presented in sentences preceded by parafoveal previews in which the vowel phoneme was concordant or discordant with the vowel phoneme in the target word. In Experiment 1, the orthographic vowel differed from the target in both the concordant and discordant preview conditions. In Experiment 2, the vowel letters in the preview were identical to those in the target word. The phonological vowel was ambiguous, however, and the final consonants of the previews biased the vowel phoneme either toward or away from the target's vowel phoneme. In both experiments, shorter reading times were observed for targets preceded by concordant previews than by discordant previews. Implications for models of word recognition are discussed.

Eye movements when reading transposed text: The importance of word-beginning letters.

Participants' eye movements were recorded as they read sentences with words containing transposed adjacent letters. Transpositions were either external (e.g., problme, rpoblem) or internal (e.g., porblem, probelm) and at either the beginning (e.g., rpoblem, porblem) or end (e.g., problme, probelm) of words. The results showed disruption for words with transposed letters compared to the normal baseline condition, and the greatest disruption was observed for word-initial transpositions. In Experiment 1, transpositions within low frequency words led to longer reading times than when letters were transposed within high frequency words. Experiment 2 demonstrated that the position of word-initial letters is most critical even when parafoveal preview of words to the right of fixation is unavailable. The findings have important implications for the roles of different letter positions in word recognition and the effects of parafoveal preview on word recognition processes.

Previewing the neighborhood: The role of orthographic neighbors as parafoveal previews in reading.

In 2 experiments, a boundary technique was used with parafoveal previews that were identical to a target (e.g., sleet), a word orthographic neighbor (sweet), or an orthographically matched nonword (speet). In Experiment 1, low-frequency words in orthographic pairs were targets, and high-frequency words were previews. In Experiment 2, the roles were reversed. In Experiment 1, neighbor words provided as much preview benefit as identical words and greater benefit than nonwords, whereas in Experiment 2, neighbor words provided no greater preview benefit than nonwords. These results indicate that the frequency of a preview influences the extraction of letter information without setting up appreciable competition between previews and targets. This is consistent with a model of word recognition in which early stages largely depend on excitation of letter information, and competition between lexical candidates becomes important only in later stages.

Use of parafoveally visible characters during the reading of Chinese sentences.

Chinese readers' use of parafoveal character previews was examined. In Experiment 1, the preview of target characters consisted of targets or of graphemically similar, homophonic, or dissimilar characters. Each preview was replaced with the corresponding target when the eyes reached the target location. Oculomotor measures revealed preview benefits for targets, for graphemically similar characters, and for homophonic characters. Experiment 2 showed that parafoveal preview of graphemically similar characters yielded benefits primarily when they shared the phonetic radical with their targets. The phonological relationship between previewed radicals and subsequently viewed targets was ineffective. Chinese character processing thus involves the initial use of orthographic information from the phonetic radical and the activation of the character's phonological form.

Semantic processing of previews within compound words.

Previous studies have suggested that previews of words prior to fixation can be processed orthographically, but not semantically, during reading of sentences (K. Rayner, D. A. Balota, & A. Pollatsek, 1986). The present study tested whether semantic processing of previews can occur within words. The preview of the second constituent of 2-constituent Finnish compound nouns was manipulated. The previews were either identical to the 2nd constituent or they were incorrect in the form of a semantically related word, a semantically unrelated word, or a semantically meaningless nonword. The results indicate that previews of 2nd constituents within compound words can be semantically processed. The results have important implications for understanding the nature of preview and compound word processing. These issues are crucial to developing comprehensive models of eye-movement control and word recognition during reading. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Preview benefit during eye fixations in reading for older and younger readers.

Older and younger readers read sentences as their eye movements were recorded, and the boundary paradigm (Rayner, 1975) was used to present either a valid or an invalid parafoveal preview of a target word. During the saccade to the target word, the preview word changed to the target word. For early measures of processing time (first fixation duration and single fixation duration), the standard preview benefit effect (shorter fixation times on the target word with a valid preview than an invalid preview) was obtained for both older and younger readers. However, for gaze duration and go-past time, the preview benefit was somewhat attenuated in the older readers in comparison to the younger readers, suggesting that on some fixations older readers obtain less preview benefit from the word to the right of fixation.

Parafoveal preview during reading: Effects of sentence position.

Two experiments examined parafoveal preview for words located in the middle of sentences and at sentence boundaries. Parafoveal processing was shown to occur for words at sentence-initial, mid-sentence, and sentence-final positions. Both Experiments 1 and 2 showed reduced effects of preview on regressions out for sentence-initial words. In addition, Experiment 2 showed reduced preview effects on first-pass reading times for sentence-initial words. These effects of sentence position on preview could result from either reduced parafoveal processing for sentence-initial words or other processes specific to word reading at sentence boundaries. In addition to the effects of preview, the experiments also demonstrate variability in the effects of sentence wrap-up on different reading measures, indicating that the presence and time course of wrap-up effects may be modulated by text-specific factors. We also report simulations of Experiment 2 using version 10 of E-Z Reader (Reichle, Warren, & McConnell, 2009), designed to explore the possible mechanisms underlying parafoveal preview at sentence boundaries.

Evidence for the use of phonological representations during transsaccadic word recognition.

The authors explored the role of phonological representations in the integration of lexical information across saccadic eye movements. Study participants executed a saccade to a preview letter string that was presented extrafoveally. In Experiment 1, the preview string was replaced by a target string during the saccade, and the participants performed a lexical decision. Targets with phonologically regular initial trigrams benefited more from a preview than did targets with irregular initial trigrams. In Experiment 2, words with regularly pronounced initial trigrams were more likely to be correctly identified from the preview alone. In Experiment 3, participants were more likely to detect a change across a saccade from regular to irregular initial trigrams than from irregular to regular trigrams. The results suggest that phonological representations are activated from an extrafoveal preview and that this phonological information can be integrated with foveal information following a saccade.

Parafoveal processing of word n + 2 during reading: Do the preceding words matter?

We used the boundary paradigm (Rayner, 1975) to test two hypotheses that might explain why no conclusive evidence has been found for the existence of n + 2 preprocessing effects. In Experiment 1, we tested whether parafoveal processing of the second word to the right of fixation (n + 2) takes place only when the preceding word (n + 1) is very short (Angele, Slattery, Yang, Kliegl, & Rayner, 2008); word n + 1 was always a three-letter word. Before crossing the boundary, preview for both words n + 1 and n + 2 was either incorrect or correct. In a third condition, only the preview for word n + 1 was incorrect. In Experiment 2, we tested whether word frequency of the preboundary word (n) had an influence on the presence of preview benefit and parafoveal-on-foveal effects. Additionally, Experiment 2 contained a condition in which only preview of n + 2 was incorrect. Our findings suggest that effects of parafoveal n + 2 preprocessing are not modulated by either n + 1 word length or n frequency. Furthermore, we did not observe any evidence of parafoveal lexical preprocessing of word n + 2 in either experiment. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Time Course of Linguistic Information Extraction From Consecutive Words During Eye Fixations in Reading.

Sequential attention shift models of reading predict that an attended (typically fixated) word must be recognized before useful linguistic information can be obtained from the following (parafoveal) word. These models also predict that linguistic information is obtained from a parafoveal word immediately prior to a saccade toward it. To test these assumptions, sentences were constructed with a critical pretarget-target word sequence, and the temporal availability of the (parafoveal) target preview was manipulated while the pretarget word was fixated. Target viewing effects, examined as a function of prior target visibility, revealed that extraction of linguistic target information began 70-140 ms after the onset of pretarget viewing. Critically, acquisition of useful linguistic information from a target was not confined to the ending period of pretarget viewing. These results favor theoretical conceptions in which there is some temporal overlap in the linguistic processing of a fixated and parafoveally visible word during reading.

A listener's investigation of printed word processing.

Examines the time course of lexical access in written-word recognition by comparing words with early and late uniqueness points (UPs). Three experiments, which used a normal (simultaneous) presentation of the letters under 3 different tasks (gender classification, naming, and semantic classification) provided no evidence for sequential processing. Rather, a small advantage in favor of words with late UP was found, which may be interpreted in terms of the lower n-gram frequencies of early-UP words. Exp 4 supported this interpretation and discussed an alternative interpretation in terms of parafoveal preview of the initial letters. A last experiment, which used an incremental presentation of the word letters, gave rise to a UP effect comparable in size to that obtained in an auditory study, suggesting that a temporal distribution of the signal is a sufficient condition for directional processing.

Transposed-letter effects in reading: Evidence from eye movements and parafoveal preview.

Three eye movement experiments were conducted to examine the role of letter identity and letter position during reading. Before fixating on a target word within each sentence, readers were provided with a parafoveal preview that differed in the amount of useful letter identity and letter position information it provided. In Experiments 1 and 2, previews fell into 1 of 5 conditions: (a) identical to the target word, (b) a transposition of 2 internal letters, (c) a substitution of 2 internal letters, (d) a transposition of the 2 final letters, or (e) a substitution of the 2 final letters. In Experiment 3, the authors used a further set of conditions to explore the importance of external letter positions. The findings extend previous work and demonstrate that transposed-letter effects exist in silent reading. These experiments also indicate that letter identity information can be extracted from the parafovea outside of absolute letter position from the first 5 letters of the word to the right of fixation. Finally, the results support the notion that exterior letters play important roles in visual word recognition. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Adult age differences in the perceptual span during reading.

Following up on research suggesting an age-related reduction in the rightward extent of the perceptual span during reading (Rayner, Castelhano, & Yang, 2009), we compared old and young adults in an N + 2-boundary paradigm in which a nonword preview of word N + 2 or word N + 2 itself is replaced by the target word once the eyes cross an invisible boundary located after word N. The intermediate word N + 1 was always three letters long. Gaze durations on word N + 2 were significantly shorter for identical than nonword N + 2 preview both for young and for old adults, with no significant difference in this preview benefit. Young adults, however, did modulate their gaze duration on word N more strongly than old adults in response to the difficulty of the parafoveal word N + 1. Taken together, the results suggest a dissociation of preview benefit and parafoveal-on-foveal effect. Results are discussed in terms of age-related decline in resilience towards distributed processing while simultaneously preserving the ability to integrate parafoveal information into foveal processing. As such, the present results relate to proposals of regulatory compensation strategies older adults use to secure an overall reading speed very similar to that of young adults.

Parafoveal load of word N+1 modulates preprocessing effectiveness of word N+2 in Chinese reading.

Preview benefits (PBs) from two words to the right of the fixated one (i.e., word N + 2) and associated parafoveal-on-foveal effects are critical for proposals of distributed lexical processing during reading. This experiment examined parafoveal processing during reading of Chinese sentences, using a boundary manipulation of N + 2-word preview with low- and high-frequency words N + 1. The main findings were (a) an identity PB for word N + 2 that was (b) primarily observed when word N + 1 was of high frequency (i.e., an interaction between frequency of word N + 1 and PB for word N + 2), and (c) a parafoveal-on-foveal frequency effect of word N + 1 for fixation durations on word N. We discuss implications for theories of serial attention shifts and parallel distributed processing of words during reading. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Determinants of parafoveal preview benefit in high and low working memory capacity readers: Implications for eye movement control.

The experiment in this article extended studies by A. W. Inhoff and K. Rayner (see record 1988-06513-001) and J. M. Henderson and F. Ferreira (see record 1990-18858-001) to determine how the printed frequency of two adjacent words influenced the benefit of having parafoveal preview of the 2nd word. High- and low-span participants (assessed by M. Daneman and P. A. Carpenter's, [see PA, Vol 66:2775] Reading Span Test) were tested to determine whether working memory capacity influenced parafoveal preview benefit. Parafoveal preview benefit was determined by an interaction of both words' frequencies in first fixation and by the 2nd word's frequency in gaze duration. However, readers were generally fixated closer to the beginning of the 2nd word when the 1st word was low frequency. When the viewing distance confound was minimized, the prior word's frequency did affect parafoveal preview benefit. Parafoveal preview benefit did not vary between reading groups. Group distributions of fixation duration provided no evidence for J. M. Henderson and F. Ferreira's fixation cutoff model. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Eye movements and the use of parafoveal word length information in reading.

Eye movements were monitored in 4 experiments that explored the role of parafoveal word length in reading. The experiments employed a type of compound word where the deletion of a letter results in 2 short words (e.g., backhand, back and). The boundary technique (K. Rayner, 1975) was employed to manipulate word length information in the parafovea. Accuracy of the parafoveal word length preview significantly affected landing positions and fixation durations. This disruption was larger for 2-word targets, but the results demonstrated that this interaction was not due to the morphological status of the target words. Manipulation of sentence context also demonstrated that parafoveal word length information can be used in combination with sentence context to narrow down lexical candidates. The 4 experiments converge in demonstrating that an important role of parafoveal word length information is to direct the eyes to the center of the parafoveal word.

Seeing morphemes: Loss of visibility during the retinal stabilization of compound and pseudocompound words.

When stabilized, retinal image fades from vision. Earlier studies suggested that knowledge constrains the loss of vision, as disappearing images fragment into familiar subpatterns. Effects of image stabilization on word perception were used in the current study to examine effects of morphemic knowledge on stimulus fragmentations. Bimorphemic compound words (in which beginning and ending trigrams formed morphemic subword units) and monomorphemic pseudocompound words (with a similar trigram structure) were stabilized. Stimulus fragmentations generally resulted in the visibility of lexically nondistinct strings of letters. However, internal morpheme boundaries also affected the loss of vision when compound words were stabilized. Two follow-up experiments indicated that morpheme-related loss of vision was neither the result of differential forgetting rates nor of guessing bias.

Effects of realistic job previews: A comparison using an enhancement and a reduction preview.

Evaluated job previews on subsequent turnover and clarified the processes responsible for any such effects. One, enhancement preview, was constructed to enhance overly pessimistic expectations, whereas the other, reduction preview, was designed to reduce overly optimistic expectations. Subjects, 533 male and female trainees in the U.S. Army, were given either preview, both previews combined, or no preview. Pretest, posttest, and follow-up (5 weeks later) perceptual and attitudinal measures were collected, in addition to demographic and turnover data. Results indicated (a) that trainees exposed to the combined previews had significantly (p?p?p?
