Lecture 2 (post midterm) Flashcards
Physical changes
Equally as rapid in middle childhood as in early years
Motor Development (growth patterns)
5-8 cm in height; 2.75 kg each year
Motor Development (muscle coordination)
- improvement in large muscle coordination – speed and strength improve
- improvement in hand-eye coordination
Motor Development (fine motor skills)
improvement in writing, drawing, cutting and other skills
Myelinization in 6-8 year olds
myelinizaton of neural axons across the cerebral cortex affect sensory and motor development first
This is linked to improved fine motor skills and hand eye coordination
Right hemisphere lateralizarion
Increases spatial perception
L/R
relative left-right orientation imprives
Spatial Cognition in 6-8 yr olds
boys better at spatial orientation because early play enhances this ability
Visual Experience in 6-8 yr olds
helps the development of spatial perception
Overweight and obesity
- 1/2 of overweight children become over weight adults
* over weight children are predisposed to type II diabetes, cancer, and cardiovascular disease
Physical activity
1/4 of children fail to meet daily physical activity guidelines (60 mins a day of moderate-vigorous activity)
37% of children spend over 2 hours a day of screen time
BMI adv. vs disadvantage.
Adv: inexpensive and accurate 80% of the time
Disadv.: doesn’t discriminate fat from muscle
It’s difficult to target obesity in children. why?
- They’re not in control of their diet
Cognitive changes in 6-8 yr olds –– concrete operational change
- Decentration
- Reversibility
- Inductive Logic
Information Processing Skills in 6-8 yr olds
- Memory improves
- Processing efficiency (making use of short term memory) increases
- Start to use memory to process information
