Recent evidence indicates that each eye does not always fixate the same letter during reading and there has been some suggestion that processing difficulty may influence binocular coordination. We recorded binocular eye movements from children and adults reading sentences containing a word frequency manipulation. We found disparities of significant(More)
The goal of this review is to evaluate the literature on binocular coordination during reading and non-reading tasks in adult, child, and dyslexic populations. The review begins with a description of the basic characteristics of eye movements during reading. Then, reading and non-reading studies investigating binocular coordination are evaluated. Areas of(More)
We investigated the effective fusional range for written stimuli in children and adults in a natural viewing situation. We recorded binocular eye movements in children and adults during processing of stereoscopically presented words in a lexical decision task. The effect of disparity magnitude on ease of fusion caused decreased response accuracy, increasing(More)
We compared Finnish adults' and children's eye movements on long (8-letter) and short (4-letter) target words embedded in sentences, presented either normally or as disappearing text. When reading disappearing text, where refixations did not provide new information, the 8- to 9-year-old children made fewer refixations but more regressions back to long words(More)
A study is reported in which eye movements were recorded when observers attempted to make a saccade to a target in the presence of a nearby and visually identical distractor. It was found that saccade targeting accuracy was completely unaffected by the presence of the distractor, except in the cases where the distractor was on the same axis as that of the(More)
The present study examined the effects of word length on children's eye movement behaviour when other variables were carefully controlled. Importantly, the results showed that word length influenced children's reading times and fixation positions on words. Furthermore, children exhibited stronger word length effects than adults in gaze durations and(More)
Two experiments were undertaken to examine whether there is an age-related change in the speed with which readers can capture visual information during fixations in reading. Children's and adults' eye movements were recorded as they read sentences that were presented either normally or as "disappearing text". The disappearing text manipulation had a(More)
The eye movements of 24 children and 24 adults were monitored to compare how they read sentences containing plausible, implausible, and anomalous thematic relations. In the implausible condition the incongruity occurred due to the incompatibility of two objects involved in the event denoted by the main verb. In the anomalous condition the direct object of(More)
Children with developmental dyslexia show reading impairment compared to their peers, despite being matched on IQ, socio-economic background, and educational opportunities. The neurological and cognitive basis of dyslexia remains a highly debated topic. Proponents of the magnocellular theory, which postulates abnormalities in the M-stream of the visual(More)
The present study employs a stereoscopic manipulation to present sentences in three dimensions to subjects as they read for comprehension. Subjects read sentences with (a) no depth cues, (b) a monocular depth cue that implied the sentence loomed out of the screen (i.e., increasing retinal size), (c) congruent monocular and binocular (retinal disparity)(More)
