Inferring character emotions during text comprehension: a negativity bias in both cerebral hemispheres

Area of Science:

• Cognitive Neuroscience
• Psycholinguistics
• Reading Comprehension

Background:

• Limited research exists on cerebral hemisphere involvement in inferring character emotions.
• Understanding how positive versus negative valence influences emotional inference processing is unclear.

Purpose of the Study:

• To investigate the role of the left and right cerebral hemispheres in inferring character emotions.
• To examine how text valence (positive vs. negative) affects emotional inference processing.

Main Methods:

• Utilized the divided visual-field paradigm with a lexical decision task.
• Participants read texts designed to elicit positive or negative character emotion inferences.
• Target words consistent with inferred emotions were presented to either the left visual field (right hemisphere) or right visual field (left hemisphere).

Main Results:

• Facilitation effects were observed in both hemispheres when inferring negative character emotions.
• No significant facilitation effects were found when inferring positive character emotions.
• Suggests differential hemispheric processing based on emotional valence.

Conclusions:

• A negativity bias may influence reading comprehension, leading to faster inference of negative character emotions.
• Cerebral hemispheres show distinct processing patterns for positively and negatively valenced emotional inferences.
• Further research is needed to fully elucidate the neural mechanisms of emotional inference during reading.
