Later, Mary Main and her husband Erik Hesse introduced the 4th category, disorganized.
The disorganized/disoriented fourth Strange Situation classification was introduced by Mary Main and Judith Solomon, not by Main and Erik Hesse.
Full reasoning
This attribution is incorrect. The fourth Strange Situation category, disorganized/disoriented attachment, is credited in the literature to Mary Main and Judith Solomon.
A review article in Development and Psychopathology states: "In 1990, M. Main and J. Solomon introduced the procedures for coding a new 'disorganized' infant attachment classification for the Ainsworth Strange Situation procedure." A second review likewise says: "A fourth Strange Situation classification, 'disorganized/disoriented,' was added by Main and Solomon (1986, 1990)."
Erik Hesse was an important later collaborator with Main on theorizing the causes and meaning of disorganized attachment, but he was not the co-introducer of the classification itself. So the article's credit to "Mary Main and her husband Erik Hesse" misidentifies the person who co-developed the fourth category.
