Joel was a very aggressive 4-year-old boy. During emerging adulthood, he is MOST likely to:

In the context of developmental psychology, aggressive behavior in early childhood can have various long-term implications for an individual's social and academic development. Research indicates that children who exhibit high levels of aggression are at an increased risk for negative outcomes as they grow older.

These individuals may struggle with self-regulation, leading to difficulties in social interactions and academic settings. As Joel transitions into emerging adulthood, if he retains these aggressive tendencies without appropriate interventions or social support, he may find academic environments challenging and could disconnect from peers and institutional support systems. This is often reflected in higher dropout rates among individuals who engaged in aggressive behavior during their formative years.

Thus, the likelihood of dropping out of school is a consequence of the ongoing challenges related to aggressive behavior, making this outcome particularly plausible as he navigates the complexities of emerging adulthood.
