Abstract
Aims: To determine whether maternal affective and anxiety disorders are associated
with cognitive inhibitory deficits in four-year-old children utilizing a chimeric animal stroop
task, a childhood adaptation of the traditional stroop task.
Study Design: Blinded Cross-Sectional Study.
Place and Duration of Study: Department of Psychiatry, University of Colorado School
of Medicine, data collected from June 2009 to October 2010.
Methodology: Four-year-olds of mothers with (n=29) and without (n=31) a history of
affective or anxiety disorders completed a chimeric animal version of the stroop task.
Incongruent, neutral, and congruent stimuli were presented over three trial blocks. Mean
reaction time and response accuracy were the primary dependent measures.
Results: The increase in the number of incorrect responses to incongruent versus
congruent or neutral stimuli was larger for offspring of a mother with a history of an
affective or anxiety disorder than without (t=2.4, P=.02); there was no significant main
effect of maternal psychiatric illness (F(1, 58)=0.9, P=.34) or a stimulus type by maternal
illness (F(1 , 58)=1.1, P=.30) interaction on reaction time. Conclusion: The association between maternal affective and anxiety disorders and
cognitive inhibitory deficit is already identifiable by four years of age.
