A theory that holds that genetic and physiological changes (coming about naturally) contribute to developing structures of the body, which the includes the brain.

So, brain development and motor capabilities, take place almost automatically, without thinking actively about learning or being instructed.

a. Biological Maturation Theory
b. Behavioralism and Social Learning Theories
c. Cognitive-development Theories
d. Socio-cultural Theories

a. Biological Maturation Theory

a. Biological Maturation Theory

The theory that best fits the given description is option a. Biological Maturation Theory.

Biological Maturation Theory suggests that genetic and physiological changes in the body, including the brain, play a significant role in the development of structures and functions. According to this theory, brain development and motor capabilities occur naturally without the need for conscious effort, active learning, or explicit instruction.

To arrive at this answer, you need to understand the key features of each option and match them with the given description. Here's a breakdown of the other options:

b. Behavioralism and Social Learning Theories: These theories focus on the influence of the environment and conditioning on behavior. They suggest that learning and development occur through the observation, imitation, and reinforcement of behaviors.

c. Cognitive-development Theories: These theories, such as Piaget's theory, emphasize the role of cognitive processes in development. They propose that children actively construct their knowledge and understanding of the world through interactions with their environment.

d. Socio-cultural Theories: These theories, like Vygotsky's sociocultural theory, emphasize the role of social interactions and cultural factors in cognitive development. They suggest that learning and development are influenced by social interactions and cultural contexts.

By comparing the description to the features of each theory, you can conclude that the correct answer is a. Biological Maturation Theory.
