“…Our experience with families containing a schizophrenic shows that communication in these cases is very disturbed in that it is not clear and unambiguous, but vague, ambiguous, con fused, inconsistent and incongruous. From the long list of verbal and non-verbal com munication problems we will simply men tion here disqualifications, 'pseudo-acknowl edgement' (a difference of opinion presented as agreement), contradictory messages, para doxical injunctions (two incongruous mes sages imposed at different levels of logic), inability to maintain and develop a focus of attention in time, indirect strategies (tension deviated from the field of transaction in question), inconsistencies between verbal content and non-verbal elements , We have also found that, in seriously disturbed families containing a schizophren ic, intolerance of autonomy and differentia tion of the various members of the family is never openly put into words, but every incli nation towards autonomy is made to disap pear by well-known psychotic transactions such as pseudo-mutuality, perceptual de fence, and an unshared focus of attention [Fivaz et al, 1979], These communication dysfunctions have been described by many authors and we can mention only a few major publications here: Wynne et al [1963,1977]; Singer et al [1965Singer et al [ , 1966Singer et al [ , 1978; Morris and Wynne [1965]; Mishler and Waxier [1968]; Kauf mann [1972,1984]; Goldstein and Rodnick [1975]; Jacob [1975]; Wild et al [1975]; Jones [1977]; Doane [1978]; Cosnier [1981].…”
