Deviance
Definition:
Example Sentences:

(4) These symptoms, while shortlived, are similar in nature to symptoms which other authors have shown to be correlated with later increased rate of neurological deviance.
(5) Factors that favoured traumatization were: poor living conditions, interpersonal problems, limited inner resources, low self-esteem (narcissistic problems) and severe psychic deviancy.
(6) Wherever the aphasics' performance was worse than that of the controls, the deviancy-scores correlated significantly with the Token Test.
(7) Measures of communication deviance and of activity, balance and warmth, derived from two family activities, correlated significantly with 3-yr. follow-up adaptive functioning, measured by IQ.
