Infant grasping can initially be attributed to reflexes, but later it is a voluntary behavior.

Grasping

The act of gripping something firmly with the hands or arms; in developmental psychology, it refers to an important motor skill in infants.

Reflexes

are automatic, involuntary responses to stimuli that occur without conscious thought, such as blinking or the knee-jerk reaction.

Voluntary Behavior

Actions that are performed consciously and with intention, often motivated by personal choice rather than automatic reflexes.
