Which age group may display unpredictable reactions, acting either in a mature or child-like manner?

Adolescents often experience a range of emotional and behavioral changes as they undergo significant developmental transitions. During this stage, individuals may oscillate between demonstrating maturity and exhibiting child-like behaviors. This variability can be attributed to hormonal changes, the quest for identity, and the impact of peer relationships.

The late childhood and teenage years are marked by a complex interplay of cognitive, social, and emotional growth, which can result in seemingly unpredictable reactions to various situations. Adolescents may show responsibility and maturity when it comes to certain topics, such as academics or future planning, yet still engage in impulsive or immature behaviors in social settings or under stress. This fluctuation is a natural part of development as they explore their independence while still needing parental or adult guidance.

In contrast, adults typically display behaviors that are more consistent and aligned with societal expectations due to their established identities and responsibilities. Preschoolers are characterized by their developmental innocence and growing independence but are generally not in a position where maturity can be expected as they are still very much in the early stages of emotional and cognitive development. Infants, on the other hand, are primarily engaged in basic developmental tasks such as bonding and sensory exploration, and they do not exhibit the same range of behavioral maturity or immaturity as older
