Abstract
When a preview contains substituted letters (SL; markey) word identification is more disrupted for a target word (monkey), compared to when the preview contains transposed letters (TL; mnokey). The transposed letter effect demonstrates that letter positions are encoded more flexibly than letter identities, and is a robust finding in adults. However, letter position encoding has been shown to gradually become more flexible as reading skills develop. It is unclear whether letter position encoding flexibility reaches maturation in skilled adult readers, or whether some differences in the magnitude of the TL effect remain in relation to individual differences in cognitive skills. We examined 100 skilled adult readers who read sentences containing a correct, TL or SL preview. Previews were replaced by the correct target word when the reader's gaze triggered an invisible boundary. Cognitive skills were assessed and grouped based on overlapping variance via Principal Components Analysis (PCA) and subsequently used to predict eye movement measures for each condition. Consistent with previous literature, adult readers were found to generally encode letter position more flexibly than letter identity. Very few differences were found in the magnitude of TL effects between adults based on individual differences in cognitive skills. The flexibility of letter position encoding appears to reach maturation (or near maturation) in skilled adult readers.

Abstract
During the lockdowns associated with the COVID-19 pandemic, many people tried to compensate for limited face-to-face interaction by increasing digital communication. Results of a four-week experience sampling study in the German-speaking countries (N = 411 participants; k = 9791 daily questionnaires) suggest, however, that digital communication was far less relevant for lockdown mental health than face-to-face communication. Digital text-based communication (e.g., e-mail, WhatsApp, SMS) nevertheless was meaningfully associated with mental health, and both face-to-face and digital text communication were more predictive of mental health than either physical or outdoor activity. Our results underscore the importance of face-to-face communication for mental health. Our results also suggest that videoconferencing was only negligibly associated with mental health, despite providing more visual and audible cues than digital text communication.

Abstract
Purpose To investigate relations between abilities of readers and properties of words during online sentence reading, we conducted a sentence reading eye-movements study on young adults of English monolinguals from the US, who exhibited a wide scope of individual differences in standard measures of language and literacy skills. Method We adopted mixed-effects regression models of gaze measures of early and late print processing stages from sentence onset to investigate possible associations between gaze measures, text properties, and skill measures. We also applied segmented linear regressions to detect the dynamics of identified associations. Results Our study reported significant associations between (a) gaze measures (first-pass reading time, total reading times, and first-pass regression probability) and (b) interactions of lexical properties (word length or position) and skill measures (vocabulary, oral reading fluency, decoding, and verbal working memory), and confirmed a segmented linear dynamics between gaze measures and lexical properties, which was influenced by skill measures. Conclusion This study extends the previous work on predictive effects of individual language and literacy skills on online reading behavior, enriches the existing methodology exploring the dynamics of associations between lexical properties and eye-movement measures, and stimulates future work investigating factors that shape such dynamics.

Abstract
Scientific studies of language behavior need to grapple with a large diversity of languages in the world and, for reading, a further variability in writing systems. Yet, the ability to form meaningful theories of reading is contingent on the availability of cross-linguistic behavioral data. This paper offers new insights into aspects of reading behavior that are shared and those that vary systematically across languages through an investigation of eye-tracking data from 13 languages recorded during text reading. We begin with reporting a bibliometric analysis of eye-tracking studies showing that the current empirical base is insufficient for cross-linguistic comparisons. We respond to this empirical lacuna by presenting the Multilingual Eye-Movement Corpus (MECO), the product of an international multi-lab collaboration. We examine which behavioral indices differentiate between reading in written languages, and which measures are stable across languages. One of the findings is that readers of different languages vary considerably in their skipping rate (i.e., the likelihood of not fixating on a word even once) and that this variability is explained by cross-linguistic differences in word length distributions. In contrast, if readers do not skip a word, they tend to spend a similar average time viewing it. We outline the implications of these findings for theories of reading. We also describe prospective uses of the publicly available MECO data, and its further development plans.

Abstract
A common problem in eye-tracking research is vertical drift—the progressive displacement of fixation registrations on the vertical axis that results from a gradual loss of eye-tracker calibration over time. This is particularly problematic in experiments that involve the reading of multiline passages, where it is critical that fixations on one line are not erroneously recorded on an adjacent line. Correction is often performed manually by the researcher, but this process is tedious, time-consuming, and prone to error and inconsistency. Various methods have previously been proposed for the automated, post hoc correction of vertical drift in reading data, but these methods vary greatly, not just in terms of the algorithmic principles on which they are based, but also in terms of their availability, documentation, implementation languages, and so forth. Furthermore, these methods have largely been developed in isolation with little attempt to systematically evaluate them, meaning that drift correction techniques are moving forward blindly. We document ten major algorithms, including two that are novel to this paper, and evaluate them using both simulated and natural eye-tracking data. Our results suggest that a method based on dynamic time warping offers great promise, but we also find that some algorithms are better suited than others to particular types of drift phenomena and reading behavior, allowing us to offer evidence-based advice on algorithm selection.

Is the author recognition test a useful metric for native and non-native English speakers? An item response theory analysis. Behav Res Methods 2021; 53:2226-2237.

Abstract
Studies of reading have shown the “Matthew effect” of exposure to print on reading skill: poor readers avoid reading, and ability develops more slowly compared to peers, while good readers improve more quickly through increased exposure. Yet it is difficult to determine just how much an individual reads. The Author Recognition Test (ART, Stanovich & West Reading Research Quarterly, 24(4), 402-433, 1989) and its multilingual adaptations are often used for quantifying exposure to print and have shown high validity and reliability in proficient readers in their dominant language (L1). When studying bilingualism and second language acquisition, it is ideal to have a single test which is equally reliable for all cohorts for comparison, but it is unclear whether ART is effective for speakers of English as a foreign language (L2). This study assesses the reliability of ART in English-medium university and college students with different language backgrounds. Following Moore and Gordon (Behavior Research Methods, 47(4), 1095-1109, 2015), we use item response theory (IRT) to determine how informative the test and its items are. Results showed an expected gradient in ART performance, with L1 speakers showing higher scores than L2 speakers of English, university students showing higher scores than college students, and both cohorts performing better than students in an English as a second language (ESL) university pre-admission program. IRT analyses further revealed that ART is not an informative measure for L2 speakers of English, as most L2 participants show a floor effect. Reasons for this unreliability are discussed, as are alternative measures of print exposure.

Abstract
Reading is an important skill for human beings to obtain information, whose acquisition is a major learning task for children. Especially, compared with single word reading, text reading requires an integration of multiple cognitive processes, which makes its underlying neural developmental mechanism not only extremely complicated but also remained poorly understood. Employing the graph theory analysis method, the present study explored the development of brain in the context of story reading from the perspective of connectomics. Forty-two primary school students and thirty-two adults read the stories in the functional magnetic resonance imaging (fMRI) experiment. We found that compared with children, adults had increased connectivity strength, nodal degree, and modular interactions for vision-related and semantics-related brain regions while decreased connectivity strength, nodal degree, and modular interactions for phonology-related brain regions. Brain-behavior association analysis suggested that the transmission to vision-related brain circuits would enhance the reading performance in adults, whereas phonology-related brain circuits played important roles in children’s reading before they develop into fluent readers. Collectivity, we highlight a shift from reliance on phonology-related networks to semantics-related and vision-related networks with age for text reading, which provides insights into the underlying neural signature of developmental cognitive mechanisms.

Abstract
The CompLex database presents a large-scale collection of eye-movement studies on English compound-word processing. A combined total of 440 participants completed eye-tracking experiments in which they silently read unspaced English compound words (e.g., goalpost) embedded in sentence contexts (e.g., Dylan hit the goalpost when he was aiming for the net.). Three studies were conducted using participants representing the non-college-bound population (300 participants), and four studies included participants recruited from the student population (140 participants). The database comprises trial-level eye-movement data (47,763 trials), participant data (including a measure of reading experience estimated via the Author Recognition Test), and lexical characteristics for the set of 931 English compound words used as critical stimuli in the studies. One contribution of the present paper is a set of regression analyses conducted on the full database and individual experiments. We report that the most reliable and consistent main effects were those elicited by compound word length, left constituent frequency, right constituent frequency, compound frequency and semantic transparency. Separately, we also found that the effect of left frequency and compound word length is weaker among more frequent compounds. Another contribution is a power analysis, in which we determined the sample sizes required to reliably detect effect sizes that are comparable to those observed in our regression models. These sample size estimates serve as a recommendation for researchers wishing to either collect eye-movement data for compound word reading, or use the current database as a resource for the study of English compound word processing.

Abstract
Previous research has generally focused on understanding individual variation in either on-line processing or off-line comprehension even though some theories explicitly link difficulty in processing to comprehension problems. The goal of the current study was to examine individual variation in performance both during on-line and off-line reading measures. A battery of psycholinguistic and cognitive tests was administered to community college and university students. In addition, participants read texts in an eye-tracker and answered comprehension questions about them. Multi-level modeling was used to determine the individual-difference factors that modulated the relation between word-level characteristics (e.g., length, frequency, surprisal) and fixation durations. The analyses showed that language experience, decoding, and WMC interacted with word characteristics to influence fixation durations, whereas language experience and reasoning predicted comprehension. The results suggest that individual variation in processing does not map directly to variation in comprehension as some theories predict.
