概要 All Hebrew words are composed of two interwoven morphemes: a tri-consonantal
root and a phonological word pattern. Models of lexical organization in
Hebrew suggest that words are organized in the mental lexicon by a morphological
principle, and probably stored in clusters
of word families defined by a shared root (Frost et al., 1997). In this case,extracting
the root letters from the printed word would be the initial step in Hebrew
visual word recognition. Two main experimental paradigms
serve for the purpose of examining morphological processing of printed words:
Masked priming, and parafoveal preview benefit. In masked priming
a pattern mask is presented before the prime, with a very brief temporal interval
between the onset of the priming stimulus and the subsequent target stimulus.
Thus the prime itself is unavailable for report. In the parafoveal
preview benefit paradigm, the benefit of information
perceived in the parafovea before the eyes actually land on a target word
is measured. The comparison between masked priming and parafoveal preview
benefit effects is compelling because both paradigms tap early processes of
word recognition, and both are relatively free of strategic effects. This
is because in both paradigms readers are unable to consciously identify
the initially presented stimulus. Results obtained using both procedures
in parallel reveal that Hebrew readers decompose printed words into their
morphemic constituents and use the root information for lexical access.
