Final answer:
The self-concept of older adults is generally more stable compared to younger adults and there is no clear difference in terms of positivity or negativity.
Step-by-step explanation:
The self-concept of older adults and younger adults differ in several ways. Firstly, older adults generally have a more stable self-concept compared to younger adults. This is because older adults have had more life experiences and have had more time to develop a cohesive sense of self. On the other hand, younger adults may still be exploring different aspects of themselves and forming their self-concept.
Secondly, there is no clear difference in terms of positivity or negativity in the self-concept between the two groups. Both older and younger adults can have positive or negative self-concepts depending on their individual experiences and beliefs.
Overall, while younger adults may still be in the process of developing their self-concept, older adults generally have a more stable sense of self due to their life experiences.
