Explanation
Reflexes are unlearned involuntary responses that happen automatically when a stimulus is present. These responses are not consciously controlled and are often essential for survival. They serve as a rapid and immediate reaction to a specific stimulus, without the need for prior experience or learning. Reflexes can be observed in various parts of the body, such as the nervous system, muscles, and organs, and they play a crucial role in protecting the body from harm and maintaining homeostasis.

Explanation
Attachment refers to the positive emotional bond that forms between a child and a specific individual, usually a caregiver. This bond is crucial for a child's emotional and social development, as it provides them with a sense of security, comfort, and trust. Through attachment, children learn to regulate their emotions, explore their environment, and form healthy relationships with others. It is a fundamental aspect of human development and plays a significant role in shaping a child's overall well-being and future relationships.
