Elective mutism was described as " a continuous refusal to speak in almost all social situations " despite normal ability to speak.
Subjects covered in her books include autism, Tourette syndrome, sexual abuse, fetal alcohol syndrome, and elective mutism ( now called selective mutism ), her specialty.
The " Diagnostic and Statistical Manual of Mental Disorders " ( DSM ), first published in 1952, first included Elective Mutism in its third edition, published in 1980.
Elective mutism in the third edition revised ( DSM III-R ) is described similarly to the third edition except for specifying that the disorder is " not " related to social phobia.
In 1980, a study by Torey Hayden identified what she called four " subtypes " of elective mutism ( as it was called then ), although this set of subtypes is not in current diagnostic use.
