Word skipping during the lexical acquisition process

During reading, most words are identified in the fovea through a direct fixation; however, readers also identify some words in the parafovea without directly fixating them. This word skipping process is influenced by many lexical and visual factors including word length, launch position, frequency, and predictability. Although these factors are well understood, there is some disagreement about the process that leads to word skipping and the degree to which skipped words are processed. The purpose of this study was to investigate the word skipping process when readers are exposed to novel words in an incidental lexical acquisition paradigm. Participants read 18 three-letter novel words (i.e., pru, cho) in three different informative contexts each while their eye movements were monitored. They then completed a surprise test of their orthographic and semantic acquisition and a spelling skill assessment. Mixed-effects models indicated that participants learned spellings and meanings of words at the same rate regardless of the number of times that they were skipped. However, word skipping rates increased across the three exposures and reading times decreased. Results indicate that readers appear to process skipped words to the same degree as fixated words. However, this may be due to a more cautious skipping process used during lexical acquisition of unfamiliar words compared to processing of already known words.

NEUROLINGUISTICS PERSPECTIVE ON LEXICAL PERCEPTION AND SEMANTIC DISORDER OF AUTISM SPECTRUM DISORDER

Autism patients get suffer from language disorder that can be identified from the late of speaking, the problems in processing linguistic information and understanding the speech meaning. This triggers to the learning problems that is worsened by attention disorder. The language acquisition is also affected by the limited vocabularies, starting from lexical perception up to vocabularies that are parts of semantic acquisition. In neurolinguistics perspective, complexity of language disorder for the spectrum autism can be explained based on the perceptual information management and the domination of his brain hemisphere. Linguistic information is processed in monoprocessing due to different hemisphere domination that happens after the process of brain lateralizes that ends up to the base of different lexicon perceptual system and the semantic acquisition for spectrum autism so that his expressive language skill reaches far beyond his receptive language. This strengthen the argumentation that language pathology is based on the relation between brain and linguistic mechanism.<br />Keywords: Neurolinguistics, Lexical Perception, Semantic Disorder, Autism Spectrum Disorder<br /><br />
