Based on Piaget's theory of cognitive development, literature analysis on empirical studies concerning children development in the present paper is aiming at exploring children's(2~7 years old) prevailing mental age characteristics in science learning.
METHODS: Cognitive development and family environment were examined in 50 LBW children and 50 normal birth weight (NBW) children aged 15-30 months with self-made questionnaire of influential factors and Bayley scales of infant development.
Results Cognitive development scores which were tested at the age of one-years old(corrected for gestational age)shown: the scores were higher in the intervention group (P<0.001,multiple lineal regression analysis).

If these functions are well brought into play, affect can promote the cognitive development, enhance the enthusiasm of learning, contribute to fostering a good attitude to learn and improve the cooperative language learning.
