Neural Correlates of Visual versus Abstract Letter Processing in Roman and Arabic Scripts
2013
In alphabetic orthographies, letter identification is a critical process during the recognition of visually presented words. In the present experiment, we examined whether and when visual form influences letter processing in two very distinct alphabets (Roman and Arabic). Disentangling visual versus abstract letter representations was possible because letters in the Roman alphabet may look visually similar/dissimilar in lowercase and uppercase forms (e.g., c-C vs. r-R) and letters in the Arabic alphabet may look visually similar/dissimilar, depending on their position within a word (e.g., [Formula: see text] - [Formula: see text] vs. [Formula: see text] - [Formula: see text]). We employed a…
Dissociating spatial and letter-based word length effects observed in readers’ eye movement patterns
2011
In previous eye movement research on word length effects, spatial width has been confounded with the number of letters. McDonald (2006) unconfounded these factors by rendering all words in sentences in constant spatial width. In the present study, the Arial font with proportional letter spacing was used for varying the number of letters while equating for spatial width, while the Courier font with monospaced letter spacing was used to measure the contribution of spatial width to the observed word length effect. Number of letters in words affected single fixation duration on target words, whereas words’ spatial width determined fixation locations in words and the probability of skipping a wo…
The role of letter features in visual-word recognition: Evidence from a delayed segment technique.
2016
Available online 9 June 2016 Do all visual features in aword's constituent letters have the same importance during lexical access? Herewe examined whether some components of a word's letters (midsegments, junctions, terminals) are more important than others. To that end,we conducted two lexical decision experiments using a delayed segment techniquewith lowercase stimuli. In this technique a partial previewappears for 50ms and is immediately followed by the target item. In Experiment 1, the partial preview was composed of terminals+junctions,midsegments+junctions, or midsegments + terminals — a whole preview condition was used as a control. Results only revealed an advantage of the whole pre…
