Impaired emotion recognition in the semantic variant of primary progressive aphasia

Takeaway

  • Cognitive functioning and social cognition are heavily dependent on semantic knowledge.

Why this matters

    Emotion recognition is an important part of a human’s ability to navigate society. These novel findings were obtained in a unique model of semantic dementia, a neurodegenerative disease characterized by early and severe semantic memory impairments. The observation that recognition of emotions is guided by conceptual knowledge of emotions endorses a constructionist view of emotion recognition and valence processing.
