Answer:
Developmental progression of functional skills
Step-by-step explanation:
With the passage of time, a kid not only grows physically and mentally but also in his/ her cognitive abilities to perceive and understand the happening around him. He develops a a relationship sense for peers, family members and related adults. Similarly, he also develops the ability to learn the things which are quite basic for us like taking off clothing items.
These things come under the umbrella of developmental progression for functional skills. studies have shown that a kid learns to take off clothing items before he learns to put them on. Same is the case with putting on socks, a kid can take off socks by the age of 12 months which is earlier than he learns to put them off (age of 18 months) with the assistance of any elder and independently by the age of almost 4 years.
This developmental progression helps a kid to modify his behavior and to be more independent.
Hope it helps!
