Interplay of morphological configuration and language switching in numerical processing and word processing.

Area of Science:

• Psycholinguistics
• Cognitive Science
• Linguistics

Background:

• Morphological configuration varies within and between languages.
• This variability impacts word formation in tasks like number naming and compound word construction.
• Understanding this interplay is crucial for psycholinguistic models of language processing.

Purpose of the Study:

• To investigate the interaction between morphological configuration switching and language switching.
• To determine how these switches influence cognitive performance.
• To explore the integration of morphological and linguistic information in the brain.

Main Methods:

• Participants performed language comprehension tasks on two-digit numbers and language production tasks on compound words.
• Experiments involved switching between languages (German, English, Spanish) and morphological configurations.
• Language-switch cost was measured by comparing performance on switch vs. repetition trials.

Main Results:

• An under-additive switch cost pattern was observed across all experiments.
• Larger language-switch costs occurred during morphological configuration repetition compared to switching.
• This indicates morphological configuration and language are processed within a unified schema.

Conclusions:

• Morphological configuration and language are integrated into a single language-related schema.
• This integration is independent of the specific language task (comprehension vs. production).
• The findings suggest a unified cognitive mechanism for processing language structure and identity.
