We are all aware of many beliefs about the superiority of girls over boys among the very young: girls are expected to speak earlier than boys, to adjust to social requirements better than boys and at an earlier age, and to function better in activities demanding fine motor skills. Whether this is also the case among the gifted is unknown, although the study of gifted kindergarten students has been intriguing for researchers for many years. In this study, we have challenged the general belief of superior female development among preschool children by showing that the participation rate of girls among gifted preschool children is lesser than among older children. Girls who were accepted to the courses for the gifted at The Young Persons’ Institute for the Promotion of Creativity and Excellence had lower cognitive abilities than boys, even though they hardly reached a 30% participation rate. In addition, girls did not achieve significantly higher scores in either of these parameters: thinking quality, openness, social acceptability, self-confidence, persistence, attitude to problem-solving, and involvement level in conversations in the final evaluation of the performance in the Institute's activities.
