“…Three broad hypotheses are attempting to explain the origin and causes of glossolalia, emphasizing its relationship with psychopathology (i.e., disorganized thinking and speech in psychotic disorders) (Cutten, 1927;Goodman, 1973;Samarin, 1973;Spencer, 1975;Brende and Rinsley, 1979;Hempel et al, 2002;Francis and Robbins, 2003;Reeves et al, 2014), altered states of consciousness (Goodman, 1972;Kavan, 2004), and social learning (Kildahl, 1972;Malony and Lovekin, 1985;Spanos et al, 1986;Koic et al, 2005;Johnson, 2010). Despite initial research linking glossolalia to schizophrenia, mood disorders, and dissociative disorders (Cutten, 1927;Goodman, 1973;Samarin, 1973;Spencer, 1975;Brende and Rinsley, 1979;Hempel et al, 2002;Francis and Robbins, 2003;Reeves et al, 2014), there is scarce and inconsistent evidence that socially embedded glossolalia is an abnormal phenomenon (Castelein, 1984;Grady and Loewenthal, 1997;Johnson, 2010). For example, it has been shown that schizophasia (grossly disorganized and incoherent speech in schizophrenia and other psychotic disorders) is linguistically distinguishable from glossolalia (Samarin, 1973).…”
