AP PSYCHOLOGY

Detailed explanation-1: -Infant fine motor development culminates with the crucial and often unnoted voluntary release response at 12 months, shown with purposeful dropping of an object, handing it to another person, or placing it.

Detailed explanation-2: -Muscle movement is considered a motor skill when it’s voluntary. So, involuntary activities like eye blinking and breathing aren’t motor skills since you can’t improve them over time through practice and repetition. On the contrary, as the child grows and develops, they can improve voluntary muscle movement with time.

Detailed explanation-3: -Voluntary movements involve the use of large muscle groups and are typically large movements of the arms, legs, head, and torso. They are referred to as gross motor skills (or large motor skills). These skills begin to develop first.

Detailed explanation-4: -Children love to place objects into containers and empty them out! This helps them to develop their grasp and release skills and refine their eye-hand coordination skills. They start with large gross movements and often miss the container.
