Which of the following is an example of social/emotional development?

The correct choice highlights heightened levels of self-consciousness as an example of social/emotional development because this aspect is related to how individuals perceive themselves and their interactions within social contexts. Social/emotional development encompasses understanding one's own feelings, managing emotional responses, and developing social skills that influence how one relates to others. Heightened self-consciousness can affect behavior and social interactions, reflecting deeper changes in emotional awareness and social perceptions.

In contrast, improved academic performance, while an important aspect of overall development, primarily relates to cognitive growth rather than social or emotional aspects. Increased physical strength is strictly related to physical development. Similarly, the development of critical thinking skills pertains to cognitive and intellectual growth, focusing on reasoning and problem-solving abilities rather than the emotional and social dimensions that are central to the concept of social/emotional development.
