The development of courage and independence are what set preschoolers, ages three to six years of age, apart from other age groups. Young children in this category face the psychological crisis of initiative versus guilt. This includes learning how to face complexities of planning and developing a sense of judgment. During this stage, the child learns to take initiative and prepares for leadership roles and to achieve goals. Activities sought out by a child in this stage may include risk-taking behaviors, such as crossing a street alone or riding a bike without a helmet; both these examples involve self-limits.The child may also develop negative behaviors as they learn to take initiative. These negative behaviors, such as throwing objects, hitting, or yelling, can be a result of the child feeling frustrated after not being able to achieve a goal as planned.
