Basic processes in reading: semantics affects speeded naming of high-frequency words in an alphabetic script.

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Linguistics

Background:

• Previous research indicates semantic factors affect naming of low-frequency words in English and Japanese.
• Spelling-sound correspondences vary in consistency across different writing systems.

Purpose of the Study:

• To investigate the influence of semantic factors, specifically imageability, on word naming times in Persian.
• To examine how orthographic transparency (vowel specification) modulates the effect of semantics on word naming.

Main Methods:

• An experiment was conducted involving university-level readers performing a single-word naming task in Persian.
• Words varied in frequency (low and high) and orthographic transparency (opaque vs. transparent).
• Naming times were recorded and analyzed to assess the impact of imageability and transparency.

Main Results:

• Imageability significantly affected naming time for both low- and high-frequency words in opaque Persian script.
• This semantic effect was not observed when words were transparent (vowels specified).
• Opaque word characteristics appear to enhance the utilization of semantic information during naming.

Conclusions:

• Semantic factors, particularly imageability, play a significant role in single-word naming in Persian, especially for opaque words.
• The findings suggest that semantics are more influential in word naming than previously assumed, depending on orthographic properties.
• This highlights the complex interplay between orthography, semantics, and word recognition across diverse writing systems.
