article reports the results of two related studies investigating the a
ssociation between affective reactivity of cognitive functioning in sc
hizophrenia and family psychiatric history. In Study #1, we examined a
ffective reactivity of positive formal thought disorder symptoms in 29
schizophrenic inpatients. We found that thought disorder was greatly
exacerbated by negative affect in those patients with a family history
of schizophrenia (SFH) (n = 11), and not in those without the family
history (SNFH) (n = 18), In Study #2, we replicated this finding with
a stable outpatient sample (n = 10), We also administered dichotic lis
tening tests using affectively neutral and affectively negative stimul
i, and found that right-ear advantage was more markedly diminished on
the affectively negative task than on the neutral task in the SFH (n =
6) but not the SNFH (n = 4) subjects, These findings support our hypo
thesis that cognitive symptoms in schizophrenia are exacerbated by neg
ative affect, and that this affective reactivity of symptoms is associ
ated with a familial form of the disorder.
