ERP evidence for temporal differences between cross-modal and cross-domain analogical reasoning

Area of Science:

• Cognitive Neuroscience
• Psychology
• Neuroimaging

Background:

• Individuals can perform cross-domain analogies and cross-modal reasoning.
• The cognitive and neural mechanisms underlying these reasoning types are not fully understood.

Purpose of the Study:

• To investigate the behavioral and neurophysiological differences between within-domain, cross-domain, and cross-modal analogical reasoning.
• To elucidate the cognitive processes involved in accessing and processing information during analogical reasoning across different domains and modalities.

Main Methods:

• Employed a multi-to-multi learning-test paradigm combined with a four-term analogy task.
• Recorded behavioral data (reaction time, accuracy) and electroencephalography (EEG) from 30 participants.
• Compared performance and neural responses across within-domain, cross-domain, and cross-modal reasoning conditions.

Main Results:

• Behaviorally, cross-domain and cross-modal reasoning showed similar accuracy, both lower than within-domain reasoning.
• EEG revealed a larger P2 amplitude in the cross-modal condition, suggesting difficulties in accessing cross-modal information.
• A larger N400 amplitude was observed in the cross-domain condition, indicating more challenging semantic processing.

Conclusions:

• The study provides the first evidence differentiating the neural underpinnings of cross-modal and cross-domain analogical reasoning.
• P2 amplitude reflects challenges in cross-modal information access, while N400 reflects semantic processing load in cross-domain reasoning.
• Findings enhance understanding of the cognitive architecture supporting analogical reasoning across diverse information types.
