This study examines intrinsic element of infants that contributes to their developmental advancement; how mothers and teachers recognize infant temperaments by gender; and the difference between how mothers and teachers recognize infant temperament of the different gender. The research found that the difference between how mothers recognize the infant temperament and how teachers recognize infants’ temperament differences in gender was not statistically significant. Only two of the elements which showed slight differences were how mothers and teachers perceived infants’ reactivity and emotional characteristics. The research findings are contrary with previous findings due to the fact that mothers and teachers behaviors were affected by different environments and that their individualistic traits were highly reflected. As a conclusion, in order to maximize effects of childcare, mothers and teachers need to be educated about the concept of fundamental elements that contribute to development of infant temperament and how to best judge those elements.
