Word and Sentence Level Spatial Information In Reading.

چکیده
Reading is considered an inefficient activity that requires independent detection of individual letters without integrating word or sentence information. We studied the use of word- and sentence-shape information using word discrimination and reading tasks with spatially distorted text in 18 naïve observers. Threshold durations were measured as a function of the wavelength and magnitude of spatial distortion applied to text for word/non-word classification of 4 and 8 letter words, and true/false classification of 4-word sentences. Spatial distortion slowed word recognition and reading. Unlike the uni-modal tuning functions observed in noise masking studies, we find multi-modal tuning functions that correspond to maximal impairment at around 2 cycles per letter, 2 cycles per word and 2 cycles per line of text. These data imply that information at these word- and sentence-length dependent scales are important for word recognition and reading, This finding is consistent with the robustness of reading letter-substituted text, proof-reading errors and the ineffectiveness of letter-based assistive reading methods. Meeting abstract presented at VSS 2015.

متن کاملIntegration of Sentence-Level Semantic Information in Parafovea: Evidence from the RSVP-Flanker Paradigm
During text reading, the parafoveal word was usually presented between 2° and 5° from the point of fixation. Whether semantic information of parafoveal words can be processed during sentence reading is a critical and long-standing issue. Recently, studies using the RSVP-flanker paradigm have shown that the incongruent parafoveal word, presented as right flanker, elicited a more negative N400 co...

Formulaic sequence (FS) is a general term often used to refer to various types of recurrent clusters. One particular type of FSs common in different registers is lexical bundles (LBs). This study investigated whether LBs are stored and processed as a whole in the mind of language users and whether their functional discourse type has any effect on their processing. To serve these objectives, thr...
