Letter identity and position coding in the parafovea.

Letter position coding has been extensively examined in studies of isolated word identification, spurring the development of computational models. However, these models are largely restricted to explaining word identification in foveal vision, despite the fact that early lexical processing during reading occurs in the parafovea. We report four experiments that examined the flexibility of parafoveal letter identity and position coding using a variant of the same-different match task.

Looking for immediate and downstream evidence of lexical prediction in eye movements during reading.

Previous investigations of whether readers make predictions about the full identity of upcoming words have focused on the extent to which there are processing consequences when readers encounter linguistic input that is incompatible with their expectations. To date, eye-movement studies have revealed inconsistent evidence of the processing costs that would be expected to accompany lexical prediction. This study investigated whether readers' lexical predictions were observable during or downstream from their initial point of activation.

Lexical processing across the visual field.

This article reports six experiments in which participants made speeded binary decisions about letter strings that were displayed for 100 versus 300 ms at different retinal eccentricities in the left versus right visual field to examine how these variables and task demands influence word-identification accuracy and latency. Across the experiments, lexical-processing performance decreased with eccentricity, but to a lesser degree for words displayed in the right visual field, replicating previous reports. However, the effect of eccentricity was attenuated for the two tasks that required "deep" semantic judgments (e.

Are there independent effects of constraint and predictability on eye movements during reading?

Evidence of processing costs for unexpected words presented in place of a more expected completion remains elusive in the eye-movement literature. The current study investigated whether such prediction error costs depend on the source of constraint violation provided by the prior context. Participants' eye movements were recorded as they read predictable words and unpredictable alternatives that were either semantically related or unrelated in three-sentence passages.

How do task demands and aging affect lexical prediction during online reading of natural texts?

Facilitated identification of predictable words during online reading has been attributed to the generation of predictions about upcoming words. But highly predictable words are relatively infrequent in natural texts, raising questions about the utility and ubiquity of anticipatory prediction strategies. This study investigated the contribution of task demands and aging to predictability effects for short natural texts from the Provo corpus.

A multitask comparison of word- and character-frequency effects in Chinese reading.

In this study, we examined the effects of word and character frequency across three commonly used word-identification tasks (lexical decision, naming, and sentence reading) using the same set of two-character target words ( = 60) and participants ( = 82). Facilitatory effects of word frequency were observed across all three tasks. The character-frequency effects, however, were facilitatory for naming but inhibitory for both lexical decision and reading.

Understanding the visual constraints on lexical processing: New empirical and simulation results.

Word identification is slower and less accurate outside central vision, but the precise relationship between retinal eccentricity and lexical processing is not well specified by models of either word identification or reading. In a seminal eye-movement study, Rayner and Morrison (1981) found that participants made remarkably accurate naming and lexical-decision responses to words displayed more than 3 degrees from the center of vision-even under conditions requiring fixed gaze. However, the validity of these findings is challenged by a range of methodological limitations.

Assessing cognitive flexibility in anorexia nervosa using eye tracking: A registered report.

Objective: Cognitive flexibility research in anorexia nervosa (AN) has primarily focused on group differences between clinical and control participants, but research in the general population utilizing the mixed pro- anti-saccade flexibility task has demonstrated individual differences in trait anxiety are a determinant of switching performance, and switching impairments are more pronounced for keypress than saccadic (eye-movement) responses. The aim of the current research is to explore trait anxiety and differences in saccadic and keypress responding as potential determinants of performance on flexibility tasks in AN.

Method: We will compare performance on the mixed pro- anti-saccade paradigm between female adult participants with a current diagnosis of AN and matched control participants, observing both saccadic and keypress responses while controlling for trait anxiety (State - Trait Anxiety Inventory) and spatial working memory (Corsi Block Tapping Test).

Predictability effects and parafoveal processing in older readers.

Normative aging is accompanied by visual and cognitive changes that impact the systems that are critical for fluent reading. The patterns of eye movements during reading displayed by older adults have been characterized as demonstrating a trade-off between longer forward saccades and more word skipping versus higher rates of regressions back to previously read text. This pattern is assumed to reflect older readers' reliance on top-down contextual information to compensate for reduced uptake of parafoveal information from yet-to-be fixated words.

Third molar development in a London population of White British and Black British or other Black ethnicity.

Population differences in dental development between Black and White ethnic groups have been debated but not previously studied in the UK. Using inappropriate data for dental age estimation (DAE) could lead to erroneous results and injustice. Data were collected from dental panoramic radiographs of 5590 subjects aged 6-24 years in a teaching hospital archive.

Morphological preview effects in English are restricted to suffixed words.

Much of the evidence for morphological decomposition accounts of complex word identification has relied on the masked-priming paradigm. However, morphologically complex words are typically encountered in sentence contexts and processing begins before a word is fixated, when it is in the parafovea. To evaluate whether the single word-identification data generalize to natural reading, Experiment 1 investigated the contribution of morphological structure to the very earliest stages of lexical processing indexed by preview effects during sentence reading in the gaze-contingent boundary paradigm.

Performance of typical and superior face recognizers on a novel interactive face matching procedure.

Unfamiliar simultaneous face matching is error prone. Reducing incorrect identification decisions will positively benefit forensic and security contexts. The absence of view-independent information in static images likely contributes to the difficulty of unfamiliar face matching.

Repetition blindness for words and pictures: A failure to form stable type representations?

Repetition blindness (RB) is the failure to detect and report a repeated item during rapid serial visual presentation (RSVP). The RB literature reveals consistent and robust RB for word stimuli, but somewhat variable RB effects for pictorial stimuli. We directly compared RB for object pictures and their word labels, using exactly the same procedure in the same participants.

Reading proficiency predicts the extent of the right, but not left, perceptual span in older readers.

The gaze-contingent moving-window paradigm was used to assess the size and symmetry of the perceptual span in older readers. The eye movements of 49 cognitively intact older adults (60-88 years of age) were recorded as they read sentences varying in difficulty, and the availability of letter information to the right and left of fixation was manipulated. To reconcile discrepancies in previous estimates of the perceptual span in older readers, individual differences in written language proficiency were assessed with tests of vocabulary, reading comprehension, reading speed, spelling ability, and print exposure.

The time course of attentional biases in pain: a meta-analysis of eye-tracking studies.

Previous meta-analyses investigating attentional biases towards pain have used reaction time measures. Eye-tracking methods have been adopted to more directly and reliably assess biases, but this literature has not been synthesized in relation to pain. This meta-analysis aimed to investigate the nature and time course of attentional biases to pain-related stimuli in participants of all ages with and without chronic pain using eye-tracking studies and determine the role of task parameters and theoretically relevant moderators.

Is it smart to read on your phone? The impact of reading format and culture on the continued influence of misinformation.

Despite advances in digital technology that have resulted in more people accessing information via mobile devices, little is known about reading comprehension on mobile phones. This research investigated the impact of reading format by comparing sensitivity to misinformation presented either in printed texts or in digital format on mobile phones to readers of English versus Chinese. Participants read pairs of short newspaper-style articles containing a critical piece of information that was either retracted or not retracted, and were later assessed on their memory for critical and general details, as well as inferential judgements related to the retracted information.

Measuring Lexical Quality: The Role of Spelling Ability.

The construct of 'lexical quality' (Perfetti Scientific Studies of Reading 11, 357-383, 2007) is widely invoked in literature on word recognition and reading to refer to a systematic dimension of individual differences that predicts performance in a range of word identification and reading tasks in both developing readers and skilled adult populations. Many different approaches have been used to assess lexical quality, but few have captured the orthographic precision that is central to the construct. This paper describes, evaluates, and disseminates spelling dictation and spelling recognition tests that were developed to provide sensitive measures of the precision component of lexical quality in skilled college student readers - the population that has provided most of the benchmark data for models of word recognition and reading.

The effect of contextual plausibility on word skipping during reading.

Recent eye-movement evidence suggests readers are more likely to skip a high-frequency word than a low-frequency word independently of the semantic or syntactic acceptability of the word in the sentence. This has been interpreted as strong support for a serial processing mechanism in which the decision to skip a word is based on the completion of a preliminary stage of lexical processing prior to any assessment of contextual fit. The present large-scale study was designed to reconcile these findings with the plausibility preview effect: higher skipping and reduced first-pass reading times for words that are previewed by contextually plausible, compared to implausible, sentence continuations that are unrelated to the target word.

The influence of number of syllables on word skipping during reading revisited.

Fitzsimmons and Drieghe (Psychonomic Bulletin & Review, 18, 736-741, 2011) showed that a monosyllabic word was skipped more often than a disyllabic word during reading. This finding was interpreted as evidence that syllabic information was extracted from the parafovea early enough to influence word skipping. In the present, large-scale replication of this study, in which we additionally measured the reading, vocabulary, and spelling abilities of the participants, the effect of number of syllables on word skipping was not significant.

Semantic repetition blindness and associative facilitation in the identification of stimuli in rapid serial visual presentation.

Repetition blindness (RB) is the inability to detect both instances of a repeated stimulus during rapid serial visual presentation (RSVP). Prior work has demonstrated RB for semantically related critical items presented as pictures, but not for word stimuli. It is not known whether the type of semantic relationship between critical items (i.

Team ball sport participation is associated with performance in two sustained visual attention tasks: Position monitoring and target identification in rapid serial visual presentation streams.

We investigated the relationship between participation in team ball sports and performance in two sustained spatiotemporal attention tasks-a position monitoring variant of the multiple object tracking (MOT) task and target identification in the rapid serial visual presentation (RSVP) task. Thirty participants were asked about the frequency of their participation in team ball sports and undertook both the MOT task and RSVP task. In the MOT task, participants viewed an array of eight discs as they moved unpredictably for 3-8s before disappearing.

Spelling ability selectively predicts the magnitude of disruption in unspaced text reading.

We examined the effect of individual differences in written language proficiency on unspaced text reading in a large sample of skilled adult readers who were assessed on reading comprehension and spelling ability. Participants' eye movements were recorded as they read sentences containing a low or high frequency target word, presented with standard interword spacing, or in one of three unsegmented text conditions that either preserved or eliminated word boundary information. The average data replicated previous studies: unspaced text reading was associated with increased fixation durations, a higher number of fixations, more regressions, reduced saccade length, and an inflation of the word frequency effect.

Individual differences in automatic semantic priming.

This research investigated whether masked semantic priming in a semantic categorization task that required classification of words as animals or nonanimals was modulated by individual differences in lexical proficiency. A sample of 89 skilled readers, assessed on reading comprehension, vocabulary and spelling ability, classified target words preceded by brief (50 ms) masked primes that were either congruent or incongruent with the category of the target. Congruent primes were also selected to be either high (e.
