How technology effects cognitive development and language development

Effects of screen time according to Dr. Michael Rich

Child only get the partial experience of a conversation, weakening their social skills and interpersonal skills.

"...screen time impacts language development in children, finding that children who spent more time on a screen instead of talking suffered in their language development. Rich said this is concerning because face-to-face interaction is drastically different than what a screen can offer".

The age of screen time use is a greater factor than amount of screen time. After 2 years old it is more suitable.

Replacing human interaction with screens can lead to negative behavior patterns later in life, often called a screen addiction. (Perhaps replacing actual human interaction).

Using technology to 'babysit" a child robs them of an experience to build on their skills such as their motor skills and following a recipe/directions when a parent is cooking.

Are only able to recognize someone if they had previously met them before, and not only seen/heard on a screen.

"Face-to-face communication with another human being is much more richer, much more protective and meaningful in the sense of human connection ... than even talking on the phone."

young children have a much more difficult time
understanding that the sound they’re hearing
belongs to an actual person when they have a lot of screen time.

Effects of screen time according to M.D
Perri Klass

It shows association, not causation. If there is a direct link, it may have less to do with the screens themselves, and more with what the screen time may be replacing in children’s lives.

Believes screes are not exactly bad but screen times may not be good in the hands of infants-toddlers-preschoolers.

Children with a higher screenQ had weaker
myelin. (The amount of myelin around a nerve fiber is directly related to how often it’s stimulated, how often it’s used).

It replaces constructive activities like
reading, playing, talking.

Children with higher screen exposure had poorer expressive language and did worse on tests of language processing speed, like rapidly naming objects.
