Alexithymia

Alexithymia is a term coined by psychotherapist Peter Sifneos in 1973 to describe a state of deficiency in understanding, processing, or describing emotions. The word comes from the  Ancient Greek literally meaning "without words for emotions".

Alexithymia is defined by:

1. difficulty identifying feelings and distinguishing between feelings and the bodily sensations of emotional arousal
2. difficulty describing feelings to other people
3. constricted imaginal processes, as evidenced by a scarcity of fantasies
4. a stimulus-bound, externally oriented cognitive style.

The alexithymia construct is strongly inversely related to the concepts of psychological mindedness and emotional intelligence.
