Orthographic and phonemic coding for lexical access: evidence from Hebrew.
Summary
Hebrew readers rely more on visual word forms than sound when recognizing words in isolation. This study found orthographic cues are prioritized over phonemic information for lexical access in Hebrew.
Area of Science:
- Cognitive Psychology
- Linguistics
- Neuroscience
Background:
- Hebrew script omits vowel points in print, creating ambiguity.
- Context is crucial for Hebrew readers to disambiguate word meanings and pronunciations.
- The role of phonemic mediation in lexical access for Hebrew remains under-explored.
Purpose of the Study:
- To investigate the influence of phonemic ambiguity on lexical access in printed Hebrew words presented without vowel points.
- To compare the roles of orthographic and phonemic codes in Hebrew word recognition.
Main Methods:
- Two experiments used consonant strings with single vs. multiple pronunciations to test phonemic ambiguity.
- A lexical decision task assessed word recognition speed.
- A third study examined decisions on nonword homographs versus homophones with vowel points.
Main Results:
- Naming was slower for phonemically ambiguous strings.
- Lexical decision times were not significantly affected by phonemic ambiguity.
- Nonword homographs were rejected slower than nonword homophones when vowels were present.
Conclusions:
- Orthographic codes appear to play a more significant role than phonemic codes in Hebrew word recognition, especially in isolation.
- Findings suggest differences in word recognition processes between Hebrew and other languages with more explicit vowel representation.
