Sažetak:
Ability to read requires numerous prerequisites to be succesfully performed. Recognition of particular letter string as a mother tongue word is certainly one of it. Neuroimaging studies attributte word recognition to the processes carried out by left ventral pathway. It has been shown that lexical decision elicites N400 effect in left inferofrontal region implying different processing of meaningful and meaningless letter string. However, various studies support importance of early left ventral pathway involvement in visual word recognition. Our study used masked priming paradigm on lexical decision task in order to descibe early and late components of visual word recognition in adult participants. Three types of masked prime (identical words + two types of graphically degraded words) preceded words or pseudowords by 80 ms and were masked by a string of "#". In total 60 words and pseudowords was presented. Masked priming paradigm reveals that masked prime presented prior to target letter string can modulate early components of visual processing such as N2 and N250. Such early modulations can facilitate or interfere with higher-level word processing. Consequently, it is suggested that if disrupted, early visual processing could underlie reading difficulties.
