Alexithymia

A subclinical condition in which a person has marked difficulty identifying, describing, and distinguishing their own emotions, often accompanied by an externally oriented thinking style and limited imagination about inner states. Alexithymia commonly co-occurs with autism, ADHD, anxiety disorders, depression, and post-traumatic stress, and it interacts with metacognition: if someone cannot tell which emotion they are feeling, they cannot regulate it well or use emotional cues to guide attention and planning. In accessibility, alexithymia matters for the design of journaling apps, mood trackers, AI companions, and AAC tools, all of which often assume the user can label emotions on demand.
