Background: It was shown that children with attention deficit disorder (ADD) have cognitive deficit, particularly deficit in working memory (Martinussen et al., 2012). In our previous research we have revealed that ADHD children have deficit in visual memory in delayed recall condition in comparison to immediate condition (Kiselev, 2018). The goal of this research was to examine the hypothesis that children with ADD have a deficit in verbal memory in delayed recall condition.

Methods: The experimental group included 18 children with ADD at the age of 5-6 years. The control group included 18 typically developing children. The children from groups were matched for IQ, gender and age.

Children from both groups were assessed with verbal memory test from Luria’s neuropsychological battery. This test is designed to assess reproducing the 6 words in immediate and delayed recall conditions. ANOVA with repeated measures was used to reveal group differences in reproducing the words in two conditions.

Results: We have not revealed significant differences between children from experimental and control group in reproducing the words in immediate condition. However, the interaction of condition type and group was significant [F(1,34)=8,12; p=0,003)]. Children with ADD had weakness in reproducing the words in delayed recall condition.

Conclusions: In view of our previously received results in children with ADD, we can propose that deficit in memory in delayed recall condition can be one of the key symptoms in this disorder.
