Bilingual reading of compound words

Area of Science:

• Psycholinguistics
• Cognitive Science
• Neuroscience

Background:

• Compound words are common in many languages, including English and Korean.
• Understanding how bilinguals process these words is crucial for cognitive linguistics.
• Previous research suggests morphological processing plays a role in word recognition.

Purpose of the Study:

• To investigate if bilingual readers activate constituent parts of compound words in one language while processing compounds in another.
• To examine the role of morphological decomposition in cross-language activation.
• To explore how constituent frequency influences this process.

Main Methods:

• Two experiments were conducted using a lexical decision task with adult Korean-English bilinguals.
• Experiment 1: Assessed English compound word recognition based on the Korean translation equivalents of their constituents.
• Experiment 2: Manipulated the frequency of the second constituent in English compound words.

Main Results:

• Lexical decision accuracy for English compounds improved when their Korean translated counterparts were real words.
• This effect was more pronounced for English compounds with high-frequency second constituents.
• Results indicate that morphological decomposition occurs across languages during bilingual reading.

Conclusions:

• Bilingual readers engage in morphological decomposition when processing compound words.
• Cross-language activation occurs between constituent parts of compound words.
• The frequency of word constituents influences the degree of cross-language activation.
