Concrete Objects: Concrete objects are physical entities that can be perceived by the senses. They have a direct presence in the real world and can be touched, seen, heard, smelled, or tasted.
Sensorimotor Stage: According to Jean Piaget's theory of cognitive development, this stage (from birth to about 2 years old) is characterized by children exploring and understanding the world through their senses and motor actions.
Perceptual Learning: Perceptual learning refers to acquiring knowledge or skills through sensory experiences and repeated exposure to stimuli. It involves becoming more attuned to perceiving and recognizing specific features or patterns in the environment.
