Which developmental stage is primarily concerned with industry versus inferiority?

The developmental stage primarily concerned with industry versus inferiority is identified as the school age stage, which typically encompasses children aged 6 to 12 years. This stage, according to Erik Erikson's psychosocial development theory, is critical for developing a sense of competence and pride in one's abilities and achievements.

As children engage in new tasks, learn skills, and interact with peers, they seek to establish a sense of industry—essentially, the confidence in their ability to tackle challenges and succeed in activities such as academics, athletics, and arts. Successfully navigating this stage leads to feelings of accomplishment, while struggles or failures might result in feelings of inferiority, leading to a lack of confidence.

Thus, the school age stage is pivotal as children begin to view themselves in relation to their peers and the wider world, laying the foundation for their self-esteem and motivation in later life stages.
