Morphological Assessment Features and their Relations to Reading: A Meta-Analytic Structural Equation Modeling Study.

Area of Science:

• Linguistics
• Developmental Psychology
• Education

Background:

• Morphemes are the smallest meaningful language units, crucial for grammatical and semantic understanding.
• Morphological knowledge significantly impacts children's word reading and reading comprehension.
• Varied assessment methods complicate the interpretation of morphology's relationship with reading outcomes.

Purpose of the Study:

• To investigate how different features of morphological knowledge assessments relate to reading outcomes.
• To examine the moderating effects of age and reading ability on these relationships.
• To inform the design of effective morphological interventions for improving reading skills.

Main Methods:

• A meta-analysis of 103 studies using meta-analytic structural equation modeling (MASEM).
• Meta-regression techniques were employed to analyze moderators like age and reading ability.
• Common assessment features (written vs. oral, spelling vs. no spelling) were analyzed.

Main Results:

• Written morphological assessments were more predictive of word reading than oral ones.
• Morphological spelling assessments were stronger predictors of both word reading and comprehension.
• Age moderated the morphology-word reading link, with a stronger association in younger children.
• Younger children showed stronger links between reading comprehension and various task dimensions, including oral and context-based tasks.

Conclusions:

• The modality and specific features of morphological assessments significantly influence their predictive power for reading outcomes.
• Orthography and spelling are critical components for effective morphological interventions.
• Intervention studies should consider age-specific strengths and utilize written, spelling-focused tasks for optimal results.
