On the relation between single word and multiple word processing during learning to read.

Area of Science:

• Developmental psychology
• Cognitive neuroscience
• Educational psychology

Background:

• Reading development involves both single word and multiple word processing.
• Understanding the developmental trajectory of these skills is crucial for identifying reading difficulties.

Purpose of the Study:

• To investigate the developmental progression of single and multiple word processing in French-speaking children.
• To identify the relationship between these two skills and their developmental interdependence.

Main Methods:

• 150 French-speaking children (Grades 2-6) completed a Lexical Decision Task (LDT) for single words and a Grammatical Decision Task (GDT) for word sequences.
• Signal detection theory and cluster analysis were employed to analyze performance across varying display times.

Main Results:

• All children demonstrated proficiency in single word processing (LDT).
• Multiple word processing (GDT) ability emerged significantly in Grade 4 and Grade 6.
• A specific threshold in single word processing efficiency (LDT sensitivity of 1.95, achieved by Grade 3) predicted successful multiple word processing.

Conclusions:

• Efficient single word processing is a prerequisite for developing multiple word processing skills.
• The maturation of multiple word processing is a gradual process that extends over several years.
• Early identification of single word processing efficiency can predict later development of more complex reading skills.
