In the present study, the effect of postnatal stressor on the spontaneous behavior of adult male rats was evaluated. A method of positive habituation based on a detailed analysis of behavioral patterns and attention of animals to a stimulus object was used. Twenty-four dams and twenty-four of their male progeny were used. Pups were divided into three groups (n = 8): controls (C), maternal social stressor (S), maternal social and physical stressors (SW). Animals (postnatal day 70-80) were individually placed in the open field arena in two habituation sessions with a 24-h delay between them (Test day 1 and Test day 2). Before the start of third session (Test day 3) a solid object was fixed in the center of the arena. Each test lasted 10 min. Our results showed the habituation effect in both stressed-groups. Although there were no significant differences in the number of investigations of the novel object among all tested groups, stress-exposed rats spent less time investigating the object. In conclusion, our findings indicate that long-term neonatal stress may impair an animal's ability to sustain attention to stimuli.
