Investigating the effect of age of acquisition of Japanese words using a lexical decision task database

Key Points

• To examine how the age at which Japanese words are learned affects cognitive processing.
• Utilized a lexical decision task to analyze word recognition.
• Created a database of age of acquisition for various Japanese words.
• Measured response times and accuracy of word decisions.
• Younger acquisition age is associated with faster response times in word recognition.
• Words learned earlier showed higher accuracy rates in lexical decisions.
• The impact of age of acquisition varied across different word types.
