Feedforward, -backward, and neutral transparency measures for Grade 1 and Grade 2 Greek readers

Area of Science:

• Linguistics
• Developmental Psychology
• Computational Linguistics

Background:

• Understanding the orthographic structure of languages is crucial for deciphering reading and spelling acquisition processes.
• Previous research has primarily focused on English orthographic transparency, necessitating studies on other languages like Greek.

Purpose of the Study:

• To introduce and analyze orthographic transparency metrics for Greek Grade 1 and Grade 2 reading materials.
• To investigate the relationship between these metrics and those of the English language.
• To explore the impact of corpus size on the reliability of these orthographic metrics.

Main Methods:

• Calculation and analysis of five orthographic transparency metrics for Greek reading materials.
• Comparative analysis of Greek metrics against established English metrics.
• Examination of metric stability across various corpus sizes.

Main Results:

• Presented novel orthographic metrics for Greek, including three novel types (neither feedforward nor feedbackward).
• Demonstrated complex interrelationships among the Greek metrics and highlighted differences compared to English.
• Found that larger corpus sizes did not significantly enhance the value of these metrics over smaller samples.

Conclusions:

• The developed orthographic metrics provide a valuable tool for researching Greek children's reading and spelling development.
• The findings underscore the language-specific nature of orthographic transparency and its implications for acquisition models.
• The study suggests that careful selection of smaller, representative corpora can be sufficient for metric analysis, optimizing research efficiency.
