Brian is four years old. He loves to watch cartoons, especially those about superheroes. His dad was also a big fan of watching
NikAS [45]

Answer:

Play stage

Explanation:

George Mead was a sociologist and a psychologist who develop a theory on how the mind and psyche develop by the interaction with other people.

Mead believed that the self develops through a three-stage role-taking process. These three stages are:

  1. preparatory stage
  2. play stage,
  3. game stage.

In the preparatory stage (usually from the moment we are born until we are 2 years old) children <u>mimic</u> what they see happening around them.

In the play stage (age 2-6), children play but they don't adhere to the rules, they make their own rules for the different games they play, this means they create rules as they play. One other characteristic of this stage is that they play representing specific people (by example, by playing to be the mom they are actually representing their mom)

In the game stage (from 7 years), children start adhering to the rules. They can also play role games but the role they play is more general (if they play as if they were a mom, they are not representing their actual mom but the concept of "being a mom" they should have by now).

In this example, Brian is <u>4 years old and likes to put on his cape when he's watching Superman and pretend to be saving the world.</u> First of all, we notice that, <em>because of his age, he should be in the play stage</em>.

But also, by pretending to be saving the world just as Superman would do we can see that<u> the role playing he is representing refers to ONE individual in particular (in this case Superman). </u>Thus he is in the play stage.

swat32

Stacey demonstrating the "children to identify fundamental units for dividing relevant objects and events into a few basic categories. "

Explanation:

The skill development in children takes place through five areas:

Cognitive Development

This is the child's ability to learn and solve problems. For example, this includes a two-month-old baby learning to explore the environment with hands or eyes or a five-year-old learning how to do simple math problems.

Social and Emotional Development

This is the child's ability to interact with others, including helping themselves and self-control. Examples of this type of development would include: a six-week-old baby smiling, a ten-month-old baby waving bye-bye, or a five-year-old boy knowing how to take turns in games at school.

Speech and Language Development

This is the child's ability to both understand and use language. For example, this includes a 12-month-old baby saying his first words, a two-year-old naming parts of her body, or a five-year-old learning to say "feet" instead of "foots".

Fine Motor Skill Development

This is the child's ability to use small muscles, specifically their hands and fingers, to pick up small objects, hold a spoon, turn pages in a book, or use a crayon to draw.

Gross Motor Skill Development

This is the child's ability to use large muscles. For example, a six-month-old baby learns how to sit up with some support, a 12-month-old baby learns to pull up to a stand holding onto furniture, and a five-year-old learns to skip.
