摘要：Cognitive abilities of low birth weight infants (1500-2000 grams) were compared to that of normal controls (2500-3500 grams) in tasks using recognition and recall measures. Three groups of infants at different ages: group I (4-6 months), group II (7-9 months), and group III (10-12 months), each consisting of 30 low birth weight and 30 controls participated in the study.
