Morphological De-com-pos-it-ion Helps Recognize Low-er Frequency Words in Typically Developing Spanish-Speaking...

Area of Science:

• Psycholinguistics
• Developmental Psychology
• Cognitive Science

Background:

• Morphological structure aids pseudoword recognition in children.
• Morphology improves visual word recognition for children with reading difficulties.

Purpose of the Study:

• To investigate the influence of morphology, word frequency, and reading proficiency on visual word recognition in typically developing Spanish-speaking children.
• To determine if morphological complexity affects word recognition based on word frequency and grade level.

Main Methods:

• A lexical decision task was administered to typically developing Spanish readers from 2nd, 4th, and 6th grades.
• Stimuli included words with manipulated morphological complexity and frequency.
• Reading proficiency was assessed by school grade.

Main Results:

• Morphological complexity significantly benefited visual word recognition accuracy for low-frequency words.
• No significant benefit of morphology was observed for high-frequency words.
• The effect of morphology was consistent across the tested grade levels.

Conclusions:

• Morpheme decomposition in Spanish visual word recognition primarily occurs for less frequent words.
• Findings support models where morphologically complex words are decomposed in the orthographic lexicon, particularly when word frequency is low.
