Development of 18-Month-Old Child

Developmental Checklist Intelligence in Infancy Cognitive: The child shows many signs of normal cognitive behavior. He seems to understand that when he bangs the blocks together that they will make sound and also seems proud of this activity. He also understood that when the blocks fell that something was wrong and said "uh oh." This is a sign of cognitive understanding of what the blocks are supposed to do. Social/emotional: The social and emotional skills are primarily illustrated by the connection and interactions with the child's mother.

The child looks completely comfortable around the mother and interacts naturally. The child is able to understand the mothers questions like "where is the banana" and responds appropriately. Physical: The child shows advanced ability to sit and stand as he wishes with minimal balance issues. The child also shows advanced visual and spatial skills that can be illustrated by his ability to work with the play blocks. He is able to stack them at least two blocks high and also makes a bridge between blocks at one point.

He is also able to point to different pictures with his hands when his mother asks. Language: The child's language seems to be fitting for his developmental stage. It is difficult to estimate what his entire vocabulary might be, but you get the sense that he understands and can say several words. He says "uh oh," "banana," and "what's that" among other similar phrases. His language is also able to interact in a social manner with his mother's questions and instructions.

Discussion The child seems to have many developmental abilities for his age and is progressing well. His motor skills and physical abilities are made evident by his ability to sit and stand as well as his ability to manipulate the blocks. Motor development milestones, such as being able to manipulate objects with the feet while walking, are commonly associated with this developmental stage (AllPsych, N.d.). Although the child is not show moving objects with his feet, he seems to manipulate objects while standing with relative ease.

He is also able to stand up from a sitting position with relative ease which is common during this stage. It is estimated that during this period a child may learn as ten new words per day and can begin to combine words in two word statements. (Cherry, N.d.). The child in the video is also able to combine words which is evident by statements such as "what's that." This would be consistent with his developmental stage.

Furthermore, the mother prompts the child to identify several objects and the child gets many of them right which indicates both cognitive and social development consistent with this stage. An opportunity to collect additional data about the child's developmental progress would include getting a better idea of the child's total vocabulary and also an idea of how many words he can understand. Although these are somewhat subjective measures, it is hard to get a count from the brief video.

However, the child seems to understand many of the objects that the mother is pointing out to the child. Some research has indicated that there can be differences in crucial aspects of early language development that correlates with socioeconomic status. The most important findings were that significant disparities in vocabulary and language processing efficiency were already evident at 18 months between infants from higher- and lower-SES families, and by 24 months there was a 6-month gap between SES groups in processing skills critical to language development (Feranld, Marchman, & Weisleder, 2012).

There obtaining a rough idea of the child's vocabulary may be able to establish the child's developmental progress more accurately. This can also provide better insights to the child's cognitive progression by getting a better understand of their vocabulary. The term cognitive development refers to the process of growth and change in intellectual/mental abilities such as thinking, reasoning and understanding; it includes the acquisition and consolidation of knowledge; infants draw on social-emotional, language, motor, and perceptual experiences and abilities for cognitive development (CA Dept. Of Educatoin, N.d.).

On the whole, from what is represented in this video, it seems that the child is developing well within the normal range of what would be expected for the child in this developmental.
