Relating Speech and Cognitive Deficits in Children Vulnerable to Psychopathology.
Harvey, Philip D.; And Others
To determine whether or not both speech and laboratory assessments of referential communication ability measure a single area of competence, three groups of children were formed on the basis of their parents' diagnostic status: schizophrenic, unipolar depressive, or bipolar disordered. The breakdown of subject groups was as follows: 23 children of schizophrenics; 43 children of unipolar depressives; 38 children of bipolar disordered; and 53 children of normal parents, who served as controls. Speech samples describing five Thematic Apperception Test (TAT) cards were collected. A cognitive task was then administered; the two conditions of this task included "Type 1" items, which were solvable solely on the basis of associative strength, and "Type 2" items, which were constructed so that the incorrect alternative response was a higher associate of the referent than the correct alternative. Two-way ANOVA's with Age and Parental Diagnosis were computed for each dependent variable. Newman-Keuls tests indicated that children of schizophrenics produced more unclear and ambiguous references than children of unipolar depressives and bipolar disordered parents. In turn, children in the last two groups produced more unclear and ambiguous references than children of normal parents. Children of schizophrenics also produced fewer explicit verbal references than all other children. Results are perceived as being important in terms of the need to actually assess speech performance before making statements about communication competence from cognitive task performance. (RH)
