During the first couple years of life, infants go through a rapid series of development relating to nearly every domain, such as motor, language, social, and cognitive development. One of the key systems to develop is the motor system. Classic theory in psychology highlights the importance of sensory experience, through the sensorimotor stage of development theorized by Jean Piaget (Piaget, 1970). While modern psychologists are not likely to maintain that development happens in stages, the basic tenants of the sensorimotor stage still stand for understanding early infant development. Taking this perspective offers several lines of questioning regarding how infants’ sensory interactions relate to how they understand their environment through …show more content…

Newborns are passive and cannot truly manipulate or explore their environment, beyond the act crying, which signals action from their caregiver. One of the first major motor milestones to develop is the onset of reaching. Prior to the ability to reach, infants are only able to sparsely contact objects that are in their direct proximity, such as the mattress of their crib or a toy a caregiver or sibling has placed beside them. With the onset of reaching, infants are now able to make direct and deliberate touches towards objects in their environment (Thelen et al., 1993). This gain in environmental exploration is crucial because it affords infants the chance to receive new sensory stimuli and begin to act on the environment. This can be imagined with the perception-action loop; the ability to reach for and touch an object, triggered by an initial visual experience of the object, can relate to a tangible grasp of the object and manipulation (Corbetta & Snapp-Childs, 2009). Further, this perception-action loop can be used to facilitate learning about object properties and how one’s interaction with objects impacts the environment (Corbetta & Snapp-Childs, 2009). Therefore, the onset of reaching triggers the start of a perceptual cycle in which infants can experience greater amounts of learning, as compared to prior to reach-onset when they were not experiencing deliberate object
