Final answer:
During the elementary school stage, children develop a sense of pride and accomplishment in their activities, combining joy in accomplishment and recognition from others for their achievements.
Step-by-step explanation:
During the elementary school stage (ages 7-11), children face the task of industry versus inferiority. Children begin to compare themselves to their peers to see how they measure up. They either develop a sense of pride and accomplishment in their schoolwork, sports, social activities, and family life, or they feel inferior and inadequate when they don't measure up.
According to Erikson's theory of psychosocial development, at this stage, children experience a sense of pride and happiness that combines joy in accomplishment and joy that a significant person recognized that accomplishment. So, the correct answers are 4) joy in accomplishment; joy that a significant person recognized that accomplishment.
