Certificate In Psychology (CPSY) Practice Exam

As infants gain more control over their hands:

1. they use the same actions on almost all objects.

2. different objects can be explored differently.

3. they experience loss of myelination in the prefrontal cortex.

4. variability among infants makes general conclusions about action difficult.

The correct answer is: different objects can be explored differently.

As infants gain more control over their hands, they begin to refine their motor skills and explore their environment in a more sophisticated manner. This development allows them to interact with different objects in ways that are appropriate to each object’s unique properties. For instance, an infant might grasp a soft toy differently than they would a small block; they may squeeze the toy while manipulating the block more carefully. This variety in exploration reflects a growing understanding of the world around them, showcasing not just increased dexterity but also cognitive advancements as they learn to differentiate between objects based on texture, shape, and functionality. The focus on each object's specific qualities allows for varied experiences that contribute to their cognitive and sensory development. This highlights the significance of motor skills in contributing to exploration and learning during infancy.
