Exam 2: Chapter 8 (Early Childhood and Biosocial Development Flashcards
what characterizes the early childhood (preschool age,, ages 2-6) changes to size and shape?
-general childhood growth
-differences and similarities between the sexes
-significant growth spurts
childhood growth from the ages of 2-6 is characterized by…
-change from chub to muscle and bone
-average weight gain of 4.5 pounds
-average height gain of 3 inches (per year)
how tall is, and how much does a 6 yo weigh?
45 lbs
42 inches tall
what are the differences and similarities between the sexes?
- boys are taller at birth
- during early childhood the sexes are proportionally the same
- maturation occurs earlier in girls
- girls weigh more initially
why do girls initially weigh more than boys?
in childhood especially society encourages girls to participate in more sedentary and calm activities as opposed to boys
what are the significant growth spurts in a childs life?
- infancy (0-2)
- adolescence
- in between
the in between growth spurts are slower and more continuous
important characteristics of neurological maturations and brain development in early childhood:
a. important ages
b. myelination
c. brain divided
what are the important ages for brain maturation and growth
Age 5- brain is at 90% of it’s adult weight
Age 7- brain is at 100% of its adult weight
-at age 7 very important cognitive and motor development occur
what is myelination?
brain growth and maturation that results in an increase in the speed of neurological signals and a decrease in interference
-helps: attention, focus, vision, and helps to screen out distractions
the brain is connected by the…
corpus callosum
the corpus callosum has its own growth spurt at age
5
what does the corpus callosum do?
coordinates both halves of the body
what is the left hemisphere of the brain responsible for, and when does it have it’s growth spurt?
responsible for:
-language
-logic
-linear sequential thinking
has growth spurt at age 2
(sensorimotor pd)
what is the right hemisphere of the brain responsible for, and when does it have it’s growth spurt?
responsibility:
-visual control & spatial tracking
-intuition and emotion
-creativity, imagination, and artistic ability
has growth spurt at age 4/5
how many words per fay can kids learn?
in the book :)
eye muscle coordination
involved in the “brain divided” concept
allows for visual tracking
pretty well underway by 5/6 years old (school time) which allows for improvement in visual tracking and hand eye coordination
what is the activity level of kids related to age progression? (emphasis on early childhood 2-6)
ages 2-3- the most active period of life
ages 3-6- more moderate activity
ages 6-9-lover activity
why does activity continue to fall off?
-school, kids become more sedentary and are less physically active q
what are the main contributors to avoidable injuries related to death (aka accidents)
-gender (boys get hurt more than girls)
-Socio-economic Status (lack of resources for prevention, divided attention)
-
rates of avoidable injuries decrease with…
age
the older kids get the more logic and reasoning they have to prevent the injuries themselves
what are the leading accidents/injuries resulting in death?
- motor vehicles
2.poisoning - drowning
why do kids often get injured with motor vehicles?
-lack of vehicle riding safety (correct carseats, kids riding in the front when they aren’t supposed to, etc.)
-children run into the road
-rise in technology (drivers are more distracted and get in more accidents)
why do kids often die/get injured through poisoning?
-kids explore the world through their mouth, so they put things in there, like pills, that they are not supposed to
-cleaners, Rxs, and tide pods are often not kept well enough away from kids (cabinets are unlocked or bottles are too easy to get into)
what was an impact of kids dying by drowning?
there is now legislation regarding fences and gates around pools
what impact the probability of avoidable injuries occurring?
- adult supervision and activities
-safety of play area
-child’s individual activity level - gender
-SES!!!!!!!
