An eye-tracking study of reading long and short novel and lexicalized compound words. J Eye Mov Res 2021; 13.

Abstract
An eye-tracking experiment examined the recognition of novel and lexicalized compound words during sentence reading. The frequency of the head noun in modifier-head compound words was manipulated to tap into the degree of compositional processing. This was done separately for long (12-16 letter) and short (7-9 letters) compound words. Based on the dual-route race model [Pollatsek et al., 4] and the visual acuity principle [Bertram & Hyönä, 2], long lexicalized and novel compound words were predicted to be processed via the decomposition route and short lexicalized compound words via the holistic route. Gaze duration and selective regression-path duration demonstrated a constituent frequency effect of similar size for long lexicalized and novel compound words. For short compound words the constituent frequency effect was negligible for lexicalized words but robust for novel words. The results are consistent with the visual acuity principle that assumes long novel compound words to be recognized via the decomposition route and short lexicalized compound words via the holistic route.

Abstract
In the Chinese writing system, there are no interword spaces to mark word boundaries. To understand how Chinese readers conquer this challenge, we constructed an integrated model of word processing and eye-movement control during Chinese reading (CRM). The model contains a word-processing module and an eye-movement control module. The word-processing module perceives new information within the perceptual span around a fixation. The model uses the interactive activation framework (McClelland & Rumelhart, 1981) to simulate word processing, but some new assumptions were made to address the word segmentation problem in Chinese reading. All the words supported by characters in the perceptual span are activated and they compete for a winner. When one word wins the competition, it is identified and it is simultaneously segmented from text. The eye-movement control module makes the decision regarding when and where to move the eyes using the activation information of word units and character units provided by the word-processing module. The model estimates how many characters can be processed during a fixation, and then makes a saccade to somewhere beyond this point. The model successfully simulated important findings on the relation between word processing and eye-movement control, how Chinese readers choose saccade targets, how Chinese readers segment words with ambiguous boundaries, and how Chinese readers process information with parafoveal vision during Chinese sentence reading. The current model thus provides insights on how Chinese readers address some important challenges, such as word segmentation and saccade-target selection.

Abstract
We employed a boundary paradigm to investigate how Chinese two-character compounds (i.e., compound words) are processed during reading. The first character of the compound was an ambiguous morpheme that had a dominant and subordinate meaning. In Experiment 1, there were three previews of the second character: identical to the target character; the preview provided subordinate biasing information (the subordinate condition); the preview provided dominant biasing information (the dominant condition). An invisible boundary was inserted between the two characters. We found that gaze durations and go-past times on the compounds were longer in the subordinate condition than those in the dominant or identical conditions. In Experiment 2, the semantic similarity between target and preview words in the dominant condition was manipulated to determine whether the differences in fixation durations in Experiment 1 resulted from the semantic similarity between the preview and target words. There were significant fixation duration differences on the target word between the dominant and subordinate conditions only when the preview and target words were semantically related. This finding indicated that the whole-word meaning plays an important role in processing Chinese compounds and that the whole-word access route is the principal processing route in reading two-character compounds in Chinese.

Abstract
This study is an evaluation of a Risk Awareness and Training Program (RAPT) designed for younger drivers. Our prior study demonstrated that a version of RAPT improved the risk perception of younger, novice drivers in a driving simulator as indicated by their eye-fixations in critical situations. The current evaluation was carried out in the field, comparing a group of younger drivers (18–21 years old) trained with RAPT with an untrained group of the same age-range. Each driver was fitted with a head-mounted portable eye-tracker that collected data during the drive (a pre-determined course of approximately 16 miles that had ten critical locations similar in concept to the scenarios in the training session). The drivers' eye-movement data, especially point of gaze, were analyzed at these ten locations. There was a significant improvement in risk perception (as indexed by fixations on pre-determined areas of potential risk) for drivers who had completed RAPT. This is the first study to show that training of any kind can have an effect on drivers' detection of risky areas in the field.

Abstract
Novice drivers have a fatality rate that is ten times higher than the most experienced group of drivers. The primary reason for this is the novice drivers' inability to predict the risks that appear in the roadway ahead. No driver education programs currently exist which teach risk awareness skills to novice drivers across a number of different scenarios. Such a program was developed and then evaluated in two experiments. In the first, 24 novice drivers completed a PC-based risk awareness training program which displayed plan views of 10 different risky scenarios. In the second, the risk awareness of these 24 trained novice drivers and an additional 24 untrained novice drivers was evaluated in an advanced driving simulator using measures of their eye movements. The set of PC trained novice drivers were more likely to recognize risks on the driving simulator, both in those scenarios studied in training and those not seen previously.

Abstract
This study explored whether readers could recognize a word composed of noncontiguous characters (a cross-character word) in Chinese reading. All 3 experiments employed Chinese 4-character strings ABCD, where both AB and CD were 2-character words. In the cross-character word condition, AC was a word but in the control condition, AC was not a word. A character identification task was employed in Experiment 1 and sentence reading tasks were employed in Experiments 2 and 3. In all 3 experiments, an AC word produced inhibition effects. In Experiment 1, an AC word decreased the accuracy of character B identification, but increased the accuracy of character C identification. In Experiments 2 and 3, an AC word slowed reading on CD, indicating that the cross-character words were activated. These results imply that Chinese character encoding leading to word recognition does not proceed in a strictly serial way from left to right, or is strictly constrained by invisible word boundaries.

Abstract
Newly licensed drivers are disproportionally involved in fatal crashes, and there is evidence that failure to attend to potentially relevant information is a major contributor to this problem. Corroborating this, in controlled scenarios on a driving simulator, we have found that younger drivers attend to (i.e., fixate) target regions in the virtual world that contain information about potential risks much less frequently than do more experienced drivers. We have developed a PC-based training program that substantially improves younger drivers' attention to these regions in the driving simulator and have recently replicated these training results on the road in a real driving situation.

Abstract
Subjects read sentences containing target words that were homophones (words with a single pronunciation but different spellings) while their eye movements were recorded A prime word was presented briefly at the onset of fixation on the target region The prime for a given target (e g, beach) was either identical to the target (beach), a phonologically similar word (the homophone beech), a visually similar nonhomophone (bench), or a dissimilar word (noise) Phonological priming effects were assessed by comparing fixation times on the target when it was preceded by the homophone versus the visually similar word Results suggest that phonological codes are automatically activated during eye fixations in reading

Abstract
Participants were asked to search for a complete O in an array consisting of eight clusters of four Landolt Cs (i.e., Os with a gap) arranged in a ring. The size of the gap in the Cs varied from cluster to cluster but was held constant within a cluster. The manual response time data were consistent with a serial self-terminating search. More importantly, eye movement data supported a serial processing model as (a) clusters were fixated serially (either clockwise or counterclockwise) on most trials and (b) fixation times on a cluster reflected processing time on that cluster and were unaffected by the gap size of either the prior or succeeding cluster. Furthermore, the pattern of fixation times on a cluster was similar to the pattern of response times in a secondary task where a single cluster was presented at fixation. These data extend the findings of Williams and Pollatsek (2007) in which search was through a linear sequence of clusters, and indicate that a serial search pattern through clusters of these kinds of objects is not confined to reading-like linear arrays.

Abstract
Using glance-monitoring technologies for on-road studies is an excellent way to investigate driver behaviors in an ecologically valid setting. Recent advances in glance-monitoring technologies have made it possible to conduct on-road studies of drivers' glance behavior that heretofore were simply not possible. Yet it is not always easy to determine which glance-monitoring technology to use for a particular application. Here, we first identify the generic capabilities of the various glance-monitoring technologies. We then describe how particular glance-monitoring technologies have been used in the field to (a) identify the skill deficiencies of novice and older drivers, (b) evaluate the effectiveness of training programs that are designed to reduce deficits in these skills, and (c) address interface issues both inside (e.g., collision warning systems) and outside (e.g., yield markings) the vehicle. The limitations and advantages of on-road eye-tracking and the associated glance-monitoring technologies are identified throughout. A comparison, where possible, is made between the results of on-road eye-tracking studies of drivers' behaviors and the results of those studies conducted in the laboratory. Overall, the use of appropriate on-road glance-monitoring technologies has greatly enhanced our theoretical understanding of why drivers behave the way they do, and this knowledge has paved the way for significant improvements in road user safety.

Abstract
Driver distraction inside and outside the vehicle is increasingly a problem, especially for younger drivers. In many cases the distraction is associated with long glances away from the forward roadway. Such glances have been shown to be highly predictive of crashes. Ideally, one would like to develop and evaluate a training program which reduced these long glances. Thus, an experiment was conducted in a driving simulator to test the efficacy of a training program, FOCAL, that was developed to teach novice drivers to limit the duration of glances that are inside the vehicle while performing an in-vehicle task, such as looking for a CD or finding the 4-way flashers. The test in the simulator showed that the FOCAL trained group performed significantly better than the placebo trained group on several measures, notably on the percentage of within-vehicle glances that were greater than 2, 2.5, and 3 s. However, the training did not generalize to glances away from the roadway (e.g., when drivers were asked to attend to a sign adjacent to the roadway, both trained and untrained novice drivers were equally likely to make especially long glances at the sign).

Abstract
Older drivers are known to look less often for hazards when turning at T-intersections or at four way intersections. The present study is an extension of Romoser & Fisher (2009) and attempts to further analyze the differences in scanning behavior between older and experienced younger drivers in intersections. We evaluated four hypotheses that attempt to explain the older drivers' failure to properly scan in intersections: difficulty with head movements, decreases in working memory capacity, increased distractibility, and failure to recall specific scanning patterns. To test these hypotheses, older and younger experienced drivers' point-of-gaze was monitored while they drove a series of simulated intersections with hidden hazards outside of the turning path. Our results suggest that none of these hypotheses can fully explain our finding that older adults are more likely to remain fixated on their intended path of travel and look less than younger drivers towards other areas where likely hazards might materialize. Instead, the results support a complementary hypothesis that at least some of the difficulties older adults have scanning intersections are due to a specific attentional deficit in the older drivers' ability to inhibit what has become their prepotent goal of monitoring the vehicle's intended path of travel, thereby causing older drivers to fail to scan hazardous areas outside this intended path of travel.

Abstract
In two experiments, we investigated how forward saccades are targeted in Chinese reading. In Experiment 1, the critical region was a 4-character string which was either a word (one-word condition) or two 2-character word phrases (two-word condition). In Experiment 2, the critical region was either a high frequency word or a low frequency word. The outgoing saccade length from the last fixation on the critical region was longer in the one-word condition than the two-word condition in Experiment 1 and was longer in the high frequency condition than in the low frequency condition in Experiment 2. These results indicate that the properties of words in a fixated region affect the length of the outgoing saccade. We propose a processing-based strategy for saccade target selection in Chinese reading in which readers estimate how many characters they can process on each fixation, and then program their next saccade so that the eyes fixate somewhere beyond them. As a consequence, the easier the processing of the fixated region is, the longer the outgoing saccade is.

Abstract
A crucial issue in word encoding is whether morphemes are involved in early stages. One paradigm that tests for this employs the transposed letter (TL) effect - the difference in the times to process a word (misfile) when it is preceded by a TL prime (mifsile) and when it is preceded by a substitute letter (SL) prime (mintile) - and examines whether the TL effect is smaller when the two adjacent letters cross a morpheme boundary. The evidence from prior studies is not consistent. Experiments 1 and 2 employed a parafoveal preview paradigm in which the transposed letters either crossed the prefix-stem boundary or did not, and found a clear TL effect regardless of whether the two letters crossed the morpheme boundary. Experiment 3 replicated this finding employing a masked priming lexical-decision paradigm. It thus appears that morphemes are not involved in early processes in English that are sensitive to letter order. There is some evidence for morphemic modulation of the TL effect in other languages; thus, the properties of the language may modulate when morphemes influence early letter position encoding.

Abstract
In this article, we extend our previous work (Reichle, Pollatsek, & Rayner, 2012) using the principles of the E-Z Reader model to examine the factors that determine when and where the eyes move in both reading and non-reading tasks, and in particular the role that word/stimulus familiarity plays in determining when the eyes move from one word/stimulus to the next. In doing this, we first provide a brief overview of E-Z Reader, including its assumption that word familiarity is the "engine" driving eye movements during reading. We then review the theoretical considerations that motivated this assumption, as well as recent empirical evidence supporting its validity. We also report the results of three new simulations that were intended to demonstrate the utility of the familiarity check in three tasks: (1) reading; (2) searching for a target word in embedded in text; and (3) searching for the letter O in linear arrays of Landolt Cs. The results of these simulations suggest that the familiarity check always improves task efficiency by speeding its rate of performance. We provide several arguments as to why this conclusion is not likely to be true for the two non-reading tasks, and in the final section of the paper, we provide a fourth simulation to test the hypothesis that problems associated with the mis-identification of words may also curtail the too liberal use of word familiarity.

Abstract
Older drivers are primarily overinvolved in crashes at intersections, and failure to attend to regions that contain relevant information about potential hazards is a major contributor to this problem. Corroborating this, we have found that older drivers in both controlled scenarios on a driving simulator and somewhat less controlled situations on the road attend to (i.e., fixate) target regions in intersections significantly less frequently than do younger experienced drivers. Moreover, we have developed a training program that substantially improves older drivers' attention to these regions. Together, these findings indicate that older drivers' less frequent scanning of regions at intersections from which hazards may emerge may be due to their developing something like an unsafe habit rather than to deteriorating physical or mental capabilities and thus that training may be effective in reducing crashes.

Abstract
Participants read sentences in which novel and lexicalized two-constituent compound words appeared while their eye movements were measured. The frequency of the first constituent of the compounds was also varied factorially and the frequency of the lexicalized compounds was equated over the two conditions. The sentence frames prior to the target word were matched across conditions. Both lexicality and first constituent frequency had large and significant effects on gaze durations on the target word; moreover the constituent frequency effect was significantly larger for the novel words. These results indicate that first constituent frequency has an effect in two stages: in the initial encoding of the compound and in the construction of meaning for the novel compound. The difference between this pattern of results and those for English prefixed words (Pollatsek, Slattery, & Juhasz, 2008) is apparently due to differences in the construction of meaning stage. A general model of the relationship of the processing of polymorphemic words to how they are fixated is presented.

Abstract
An interesting issue in reading is how parafoveal information affects saccadic targeting and fixation durations. We investigated the influence of shading selected regions of text on eye movements during reading of long and short words within sentences. A target word, either four- or eight-letters long, was presented in one of four shading conditions: the whole target word shaded; the first half shaded; second half shaded; no shading. There was no evidence of a visually mediated parafoveal-on-foveal effect. Saccadic targeting was modulated by the shading on the first half of the word, such that fixations landed closer to the beginning of the word than in the other three shading conditions. Furthermore, partial word shading, resulting in visual non-uniformity of the target word, produced longer gaze durations than the other conditions. Finally, readers spent more time re-reading target words when they were partially shaded than in the other two conditions. We suggest that our effects are due to targeting of the optimal viewing location and revisits to check words that appear visually unusual. Together, the results indicate robust effects of low-level visual characteristics of the word on oculomotor decisions of where and when to move the eyes during reading.

Abstract
Several studies have documented that the failure of drivers to attend to the forward roadway for a period lasting longer than 2-3 s is a major cause of highway crashes. Moreover, several studies have demonstrated that novice drivers are more likely to glance away from the roadway than the experienced drivers for extended periods when attempting to do a task inside the vehicle. The present study examines the efficacy of a PC-based training programme (FOrward Concentration and Attention Learning, FOCAL) designed to teach novice drivers not to glance away forthese extended periods of time. A FOCAL-trained group was compared with a placebo-trained group in an on-road test, and the FOCAL-trained group made significantly fewer glances away from the roadway that were more than 2 s than the placebo-trained group. Other measures indicated an advantage for the FOCAL-trained group as well. Statement of relevance: Distracted driving is increasingly a problem, as cell phones, navigation systems, and other in-vehicle devices are introduced into the cabin of the automobile. A training programme is described that has beentested on the open road and can reduce the behaviours that lead to crashes caused by the distracted driving.

Abstract
The threat that cell-phones pose to driving has been a well researched topic. There are fewer studies of the threat that texting creates for drivers, but the risks are obvious and the few existing studies confirm this. What is not obvious is whether frequent texters will expose themselves to the same risks as infrequent texters. This is important to know because many texters, especially teens who text frequently, may consider themselves immune to the dangers of texting while driving. As such, a comparison of frequent and infrequent texters was undertaken on a driving simulator. It is also not immediately clear what effects the different types of interfaces have on driving performance while text messaging. The interfaces under evaluation included keypad or "qwerty" phones (e.g., Blackberries) and touchpad phones (iPhone). It was found that the frequent and infrequent texters were equally likely to glance at least once for more than 2s inside the vehicle while sending a text message. It was also found that touchpad texters had a larger number of glances above the 2s threshold than keypad users, though this difference was not significant. The implications of this for future public policy are discussed.

Abstract
Young drivers (younger than 25 years of age) are overrepresented in crashes. Research suggests that a relevant cause is inadequate visual search for possible hazards that are hidden from view. The objective of this study was to develop and evaluate a low-cost, fixed-base simulator training program that would address this failure. It was hypothesized that elicited crashes in the simulator training would result in better scanning for latent hazards in scenarios that were similar to the training scenarios but situated in a different environment (near transfer), and, to a lesser degree, would result in better scanning in scenarios that had altogether different latent hazards than those contained in the training scenarios (far transfer). To test the hypotheses, 18 trained and 18 untrained young novice drivers were evaluated on an advanced driving simulator (different from the training simulator). The eye movements of both groups were measured. In near transfer scenarios, trained drivers fixated the hazardous region 84% of the time, compared with only 57% of untrained drivers. In far transfer scenarios, trained drivers fixated the hazardous region 71 % of the time, compared with only 53% of untrained drivers. The differences between trained and untrained drivers in both the near transfer scenarios and the far transfer scenarios were significant, with a large effect size in the near transfer scenarios and a medium effect size in the far transfer scenarios [respectively: U = 63.00, p(2-tailed) < .01, r = -.53, and U = 88.00, p(2-tailed)<.05,r = -.39].

Abstract
(a) The purpose of this study was to determine whether novice drivers that were trained to anticipate hazards did so better than novice drivers who were not so trained immediately after training and up to one year after training occurred. (b) Novice drivers who had held their restricted license for about one month were randomly assigned to a PC-based hazard anticipation training program (RAPT) or a placebo (control) training program. The programs took about one hour to complete. The effects of training were assessed in a field drive by using patterns of eye movements to assess whether drivers anticipated a potential unseen hazard. (c) The effects of training persisted over time. In the field test immediately after training, the RAPT group anticipated the hazards 65.8% of the time whereas; the control group anticipated them only 47.3% of the time. Six or more months later, the groups were brought back for a second field test and the effects of training did not diminish; the RAPT group anticipated the hazards 61.9% of the time compared to 37.7% for the control group.

Abstract
Novice drivers (teen drivers with their solo license for six months or less) are at a greatly inflated risk of crashing. Post hoc analyses of police accident reports indicate that novice drivers fail to anticipate hazards, manage their speed, and maintain attention. These skills are much too broadly defined to be of much help in training. Recently, however, driving simulators have been used to identify those skills which differentiate the novice drivers from older, more experienced drivers in the areas of hazard anticipation and speed management. Below, we report an experiment on a driving simulator which compares novice and experienced drivers' performance in the third area believed to contribute especially heavily to crashes among novice drivers: attention to the forward roadway. The results indicate that novice drivers are much more willing to glance for long periods of time inside the vehicle than are experienced drivers. Interestingly, the results also indicate that both novice and experienced drivers spend equal amounts of time glancing at tasks external to the vehicle and in the periphery. Moreover, just as a program has been designed to train the scanning skills that clearly differentiate novice from experienced drivers, one might hope that a training program could be designed to improve the attention maintenance skills of novice drivers. We report on the initial piloting of just such a training program. Finally, we address a question that has long been debated in the literature: Do the results from driving simulators generalize to the real world? We argue that in the case of hazard anticipation, speed management, and attention maintenance the answer is yes.

Abstract
Parafoveal preview was examined within and between words in two eye movement experiments. In Experiment 1, unspaced and spaced English compound words were used (e.g., basketball, tennis ball). Prior to fixating the second lexeme, either a correct or a partial parafoveal preview (e.g., ball or badk) was provided using the boundary paradigm (Rayner, 1975). There was a larger effect of parafoveal preview on unspaced compound words than on spaced compound words. However, the parafoveal preview effect on spaced compound words was larger than would be predicted on the basis of prior research. Experiment 2 examined whether this large effect was due to spaced compounds forming a larger linguistic unit by pairing spaced compounds with nonlexicalized adjective–noun pairs. There were no significant interactions between item type and parafoveal preview, suggesting that it is the syntactic predictability of the noun that is driving the large preview effect.

Abstract
One key issue for computational models of visual-word recognition is the time course of orthographic and phonological information during reading. Previous research, using both behavioral and event related brain potential (ERP) measures, has shown that orthographic codes are activated very early but that phonological activation starts to occur immediately afterward. Here we report an ERP masked priming experiment in Spanish that investigates this issue further by using very strict control conditions. The critical phonological comparison was between two pairs of primes having the same orthographic similarity to the target words but differing in phonological similarity (e.g., conal-CANAL vs. cinal-CANAL vis à vis ponel-PANEL vs. pinel-PANEL), whereas the critical orthographic contrast was between pairs of primes that had the same phonological similarity to the target but differing in orthographic similarity (e.g., conal-CANAL vs. konal-CANAL). Orthographic priming was mainly observed in the 150-250-ms time window whereas phonological priming occurred in the 350-550-ms window.

Abstract
In 2 experiments, eye movements were examined during searches in which elements were grouped into four 9-item clusters. The target (a red or blue T) was known in advance, and each cluster contained different numbers of target-color elements. Rather than color composition of a cluster invariantly guiding the order of search though clusters, the use of color was determined by the probability that the target would appear in a cluster of a certain color type: When the target was equally likely to be in any cluster containing the target color, fixations were directed to those clusters approximately equally, but when targets were more likely to appear in clusters with more target-color items, those clusters were likely to be fixated sooner. (The target probabilities guided search without explicit instruction.) Once fixated, the time spent within a cluster depended on the number of target-color elements, consistent with a search of only those elements. Thus, between-cluster search was influenced by global target probabilities signaled by amount of color or color ratios, whereas within-cluster search was directly driven by presence of the target color.

Can younger drivers be trained to scan for information that will reduce their risk in roadway traffic scenarios that are hard to identify as hazardous? ERGONOMICS 2009; 52:657-73.

Abstract
Younger drivers (18-21 years) are over-involved in crashes. Research suggests that one of the reasons for this over-involvement is their failure to scan areas of the roadway for information about potential risks in situations that are hazardous, but not obviously so. The primary objective of the present study is to develop and evaluate a training program that addresses this failure. It was hypothesised that PC-based hazard anticipation training would increase the likelihood that younger drivers would scan for potential hazards on the open road. In order to test this hypothesis, 12 trained and 12 untrained drivers' eye movements were measured as they drove a vehicle on local residential, feeder and arterial roads. Overall, the trained drivers were significantly more likely to gaze at areas of the roadway that contained information relevant to the reduction of risks (64.4%) than were the untrained drivers (37.4%). Significant training effects were observed even in situations on the road that were quite different from those shown in training. These findings have clear implications for the type of training of teen drivers that is necessary in order to increase their anticipation of hazards.

Abstract
The cognitive system does not just act as a mirror from the sensory input; instead, it tends to normalize this information. Given that letter processing seems to be much more specialized than digit processing in the cortex, we examined whether the regularization process occurs differently from digits to letters than from letters to digits: We employed a masked priming same/different experiment (e.g., probe, VESZED; prime, V35Z3D; and target, VESZED). When embedded in letter strings, digits that resemble letters (e.g., 3 and 5 in V35Z3D-VESZED) tend to be encoded in a letter-like manner, whereas when embedded in digit strings, letters that resemble digits (e.g., E and S in 9ES7E2-935732) tend not to be encoded in a digit-like manner.

Abstract
All programs assessing attention maintenance inside the vehicle have required eye trackers and either a driving simulator or a specially equipped field vehicle. Ideally, one would like a way to assess attention maintenance that could be implemented on a desktop PC. Additionally, one would like to have a program that could be used to train novice drivers to maintain their attention more safely on the forward roadway. An experiment was run (a) to determine whether a program FOCAL (Focused Concentration and Attention Learning) using a desktop PC could differentiate between the attention maintenance skills of novice and experienced drivers and (b) to determine whether a program that improved the hazard anticipation skills of novice drivers might also improve their attention maintenance skills. FOCAL was able to differentiate between the attention maintenance skills of novice and experienced drivers. However, hazard anticipation training did not improve the attention maintenance skills of the novice drivers.

Abstract
Kennedy and Pynte [Kennedy, A., & Pynte, J. (2008). The consequences of violations to reading order: An eye movement analysis. Vision Research, 48, 2309-2320] presented data that they suggested pose problems for models of eye movement control in reading in which words are encoded serially. They focus on situations in which pairs of words are fixated out of order (i.e., the first word is skipped and the second fixated prior to a regression back to the first word). We strongly disagree with their claims and contest their arguments. We argue that their data set was obtained selectively and the events they believe are problematic do not occur frequently during reading. Furthermore, we do not consider that Kennedy and Pynte's arguments pose serious difficulties for serial models of reading such as E-Z Reader.

Abstract
Contrasting predictions of serial and parallel views on the processing of foveal and parafoveal information during reading were tested. A high-frequency adjective (young) was followed by either a high-frequency word(n) (child) or a low-frequency word(n) (tenor), which in turn was followed by either a correct (performing) or an orthographic illegal word(n+1) (pxvforming) as a parafoveal preview. A limited parafoveal-on-foveal effect was observed: There were inflated fixation times on word(n) when the preview of word(n+1) was orthographically illegal. However, this parafoveal-on-foveal effect was (a) independent of the frequency of word(n), (b) restricted to those instances when the eyes were very close to word(n+1), and (c) associated with relatively long prior saccades. These observations are all compatible with a mislocated fixation account in which parafoveal-on-foveal effects result from saccadic undershoots of word(n+1) and with a serial model of eye movement control during reading.

Abstract
The distribution of landing positions and durations of first fixations in a region containing a noun preceded by either an article (e.g., the soldiers) or a high-frequency 3-letter word (e.g., all soldiers) were compared. Although there were fewer first fixations on the blank space between the high-frequency 3-letter word and the noun than on the surrounding letters (and the fixations on the blank space were shorter), this pattern did not occur when the noun was preceded by an article. R. Radach (1996) inferred from a similar experiment that did not manipulate the type of short word that 2 words could be processed as a perceptual unit during reading when the first word is a short word. As this different pattern of fixations is restricted to article-noun pairs, it indicates that word grouping does not occur purely on the basis of word length during reading; moreover, as the authors demonstrate, one can explain the observed patterns in both conditions more parsimoniously without adopting a word-grouping mechanism in eye movement control during reading.

Abstract
Three experiments examined the effects in sentence reading of varying the frequency and length of an adjective on (a) fixations on the adjective and (b) fixations on the following noun. The gaze duration on the adjective was longer for low frequency than for high frequency adjectives and longer for long adjectives than for short adjectives. This contrasted with the spillover effects: Gaze durations on the noun were longer when adjectives were low frequency but were actually shorter when the adjectives were long. The latter effect, which seems anomalous, can be explained by three mechanisms: (a) Fixations on the noun are less optimal after short adjectives because of less optimal targeting; (b) shorter adjectives are more difficult to process because they have more neighbors; and (c) prior fixations before skips are less advantageous places to extract parafoveal information. The viability of these hypotheses as explanations of this reverse length effect on the noun was examined in simulations using an updated version of the E-Z Reader model (A. Pollatsek, K. Reichle, & E. D. Rayner, 2006c; E. D. Reichle, A. Pollatsek, D. L. Fisher, & K. Rayner, 1998).

Abstract
Experiment 1 examined whether the semantic transparency of an English unspaced compound word affected how long it took to process it in reading. Three types of opaque words were each compared with a matched set of transparent words (i.e. matched on the length and frequency of the constituents and the frequency of the word as a whole). Two sets of the opaque words were partially opaque: either the first constituent was not related to the meaning of the compound (opaque-transparent) or the second constituent was not related to the meaning of the compound (transparent-opaque). In the third set (opaque-opaque), neither constituent was related to the meaning of the compound. For all three sets, there was no significant difference between the opaque and the transparent words on any eye-movement measure. This replicates an earlier finding with Finnish compound words (Pollatsek & Hyönä, 2005) and indicates that, although there is now abundant evidence that the component constituents play a role in the encoding of compound words, the meaning of the compound word is not constructed from the parts, at least for compound words for which a lexical entry exists. Experiment 2 used the same compounds but with a space between the constituents. This presentation resulted in a transparency effect, indicating that when an assembly route is 'forced', transparency does play a role.

Abstract
We examined how closely the underlying cognitive processing in a visual search task guides eye movements by comparing two different search tasks. In the extended search task, participants searched for an O in eight clusters of Landolt Cs with varying gap widths (four characters per cluster, arranged to look like words in text). In the single-cluster task, participants searched a single cluster (identical to the ones in the extended search). The key manipulation was gap size; although gap orientation for the distractors varied within a cluster, gap size was constant within a cluster but differed in size from cluster to cluster. The principal findings were that (1) gaze durations in the extended search were almost completely a function of the difficulty of the cluster (i.e., the gap size of the Cs) and (2) the effect of gap size on gaze durations in the extended search was very similar to its effect on response times in the single-cluster search. Thus, it appears that eye movements in the search task are determined almost exclusively by the ongoing cognitive processing on that cluster.

Abstract
Young adult and older readers' eye movements were recorded as they read sentences containing target words that varied in frequency or predictability. In addition, half of the sentences were printed in a font that was easy to read (Times New Roman) and the other half were printed in a font that was more difficult to read (Old English). Word frequency, word predictability, and font difficulty effects were apparent in the eye movement data of both groups of readers. In the fixation time data, the pattern of results was the same, but the older readers had larger frequency and predictability effects than the younger readers. The older readers skipped words more often than the younger readers (as indicated by their skipping rate on selected target words), but they made more regressions back to the target words and more regressions overall. The E-Z Reader model was used as a platform to evaluate the results, and simulations using the model suggest that lexical processing is slowed in older readers and that, possibly as a result of this, they adopt a more risky reading strategy.

Abstract
R. Kliegl, A. Nuthmann, and R. Engbert reported an impressive set of data analyses dealing with the influence of the prior, present, and next word on the duration of the current eye fixation during reading. They argued that outcomes of their regression analyses indicate that lexical processing is distributed across a number of words during reading. The authors of this comment question their conclusions and address 4 different issues: (a) whether there is evidence for distributed lexical processing, (b) whether so-called parafoveal-on-foveal effects are widespread, (c) the role of correlational analyses in reading research, and (d) problems in their analyses because they use only cases in which words are fixated exactly once.
