Unit 7 Flashcards
8.1 Height and Weight Changes
- 2 and 3 inches in height per year in early childhood
- 4 to 6 pounds a year
- boys are slightly taller and heavier than girls
8.1 Brain Development
- by age 5, brain is 90% of adult weight
- between 4 and 7 kids can block out distractions; making them ready to start school
- reading and detecting visual differences improve
8.1 Right or Left Brain?
- brain functions are not split up that nicely
- myelination occurs rapidly during childhood which is complete by age 8
- plasticity
plasticity
- tendency of new parts of the brain to take up the functions of injured parts
- most plasticity in early childhood
- two factors involved in plasticity
- “sprouting” or growing new dendrites
- can allow rearrangement of neural circuits
- redundancy of neural connections
- more than one place does the same function in brain
8.2 Gross Motor Skills
- skills that employ the large muscles used in locomotion
- great strides between ages 2-6
- girls and boys are very similar
- girls better at balancing and precision of movement
- boys better at throwing and kicking
- individual differences are greater than sex differences
- physical activity declines after 2 or 3 years, 2 to 4 years more focused attention
- twice as likely to be active if mother is active; 3.5x if father is active
- influenced by role models, influence, encouragement, and support, genetics
8.2 Fine Motor Skills
- skills that employ the small muscles used in manipulation, such as those in fingers
- lags behind gross, proximodistal development
- drawings closely linked to development of motor and cognitive skills, building blocks of art, placement, shape, design, and pictorial stages
8.2 Handedness
- emerges during infancy
- leftie=little evidence for advantage/disadvantage
- theories=may run in families, prenatal testosterone, develops early
8.3 Children’s Nutritional Health in Early Children
- need fewer calories per pound of body weight
- 2 to 3 years their appetite decreases
- strong preferences for certain foods
- excessive sugar and salt
- eating patterns of parents
8.4 Minor Illness
respiratory infections, develops antibodies
8.4 Major Illness
- examples include pneumonia, diarrhea, malaria, measles, and malnutrition
- oral rehydration therapy
- vaccines
oral rehydration therapy
treatment involving the administration of a salt and sugar solution to a child who is dehydrated from diarrhea
8.4 Role of Car Accidents
- more deaths than diseases
- low-income=more likely to die
8.5 Sleep Disorders
sleep terrors, nightmares, insomnia, and somnambulism
sleep terrors
frightening dreamlike experiences that occur during the deepest stage of non-REM sleep, shortly after falling asleep
nightmares
frightening dreams that occur during REM sleep, often in the morning hours, may associated with stress
insomnia
sleep disorder characterized by difficulty falling asleep and remaining asleep and waking early
somnambulism
sleepwalking; brief, unexcitable, lack of memory
enuresis
failure to control the bladder after the normal age (3-4) for control has been reached
bedwetting
failure to control the bladder during the night
8.4 Control of Enuresis
infection, display of hostility, symbolic masturbation learned from conditioned anxiety and situational stress
encopresis
failure to control bowels after the normal age for bowel control has been reached, more common among boys, occurs often during the day
Pre-Operational stage
second stage by Piaget, characterized by inflexible and irreversible mental manipulation of symbols
9.1 Thoughts and Behavior during PreOp
- use symbols to represent objects and relationships among them
- scribble and draw pictures
symbolic play
- play in which children make believe that objects and toys are other than what they are (pretend play)
- starts around 12-13 months
- imaginary friends =positive trait
