Which of the following is NOT a factor in an infant's sensory learning process?

Infants engage in sensory learning through experiences that involve their senses, which play crucial roles in their development. Touch, smell, and taste are all essential sensory modalities through which infants explore and learn about their environment. Each of these senses helps to build connections and understanding of the world around them.

Touch provides infants with important information about texture, temperature, and pressure, allowing them to develop fine motor skills and spatial awareness. Smell contributes to their familiarity with caregivers, food, and surroundings, which can evoke comfort and security. Taste comes into play as they begin to explore different foods, which also aids in their nutritional development.

On the other hand, math skills are not a sensory learning process but rather a cognitive skill that develops later as children grow. Infants are not engaged in mathematical reasoning; instead, their focus is on the basic sensory interactions that lay the foundation for further cognitive development. Thus, this choice stands out as the one that does not align with the sensory learning processes in the context of infant development.
