define growth & development
growth is an increase in a measured quantity (height + weight)
development is complex changes, including increase in abilities & skills
principles of growth
- growth rates are not constant
- growth rates vary between children
- different parts of the body grow at different times
- boys usually grow faster than girls
principles of development
- from head to toe
- from the inside out
- same sequence, different rates
- holistic
gross motor skills (infancy)
newborn - primitive reflexes, like grasp
1 month - lift chin, some control of head
3 months - can lift head and chest when on front
6 months - roll over, sit up for short time w/o support, kicks legs when held up
9-10 months - crawl, cruise
12-13 months - stand alone, walk without help
18 months - climbs on furniture
2 years - use tricycle, throw a large ball
2.5 years - jumps from a low step, kick a ball
fine motor skills (infancy)
newborn - holds thumb tucked into hands
1 month - opens hand to grasp a finger
3 months - can briefly grasp a rattle

4 - kick and throw a large ball
5 - hop using each foot separately

fine motor skills (childhood)
3 - can use pencil, build tower with blocks
5 - dress and undress self, tie own shoelaces, use buttons and zips
8 - draw detailed pictures
physical changes in puberty (female)
primary - uterus enlarges and vagina lengthens, ovaries begin to release eggs, menstrual cycle commences
secondary - breasts develop, hair grows in pubic area and under arms, redistribution of body fat causes hips to widen
physical changes in puberty (male)
primary - enlargement of penis and testes, spontaneous erections, testicles begin to produce sperm
secondary - voice deepens due to changes in larynx, hair grows in armpits and pubic area, facial hair, redistribution of muscle tissue and fat
physical development: early adulthood
- physical strength peaks between 19 and 28
- decline in capabilities towards end of this stage if: individuals have unhealthy diet, do not exercise regularly, maintain unhealthy lifestyle
changes in pregnancy & lactation
- increase in progesterone and estrogen, responsible for morning sickness
- change in shape and appearance of breasts: darkened veins due to increased blood supply, nipples and areoles darken, breasts sensitive and tender
symptoms of perimenopause
• hot flushes + night sweats, causing trouble sleeping
• sore breasts
• lower sex drive
• fatigue
• irregular or very heavy periods
• vaginal dryness, causing discomfort in sex
• mood swings
• urine leakage when coughing or sneezing
• urinating more frequently
signs of the ageing process (middle adulthood)
• increased weight (middle aged spread)
• skin loses elasticity
• hair loss
• muscle decline
• receding gum line
symptoms of the menopause
- no more periods
- hot flushes + night sweats
- less oestrogen and progesterone
- lower sexual interest
- possible osteoporosis
deterioration of health in older adulthood
- increased risk of organ failure and heart disease
- strength and muscle loss
- reduced stamina
- less mobility and dexterity
- slower reactions
- visual and hearing problems
- incontinence
stages of language development
3 months - babbling noises
12 months - imitating sounds carers make, like ‘da da’
2 years - two word sentences like “cat goed”
3 years - simple sentences, “i want drink”, simple questions, vocabulary grows rapidly
4 years - clear sentences, but grammar mistakes expected
5 years - full adult grammar, formal grammar continues to improve, wider vocabulary
the 4 stages of piaget’s theory of cognitive development
- sensorimotor (0-2)
- pre-operational (2-7)
- concrete operational (7-11)
- formal operational (11-18)
describe the sensorimotor stage
infant explores the world via its immediate senses and the actions they perform, lacks internal schemata, egocentric, lacks object permanence
pre operational stage
child creates and adds to schemata, very influenced by sight, fails to carry out logical operations and show centration, lack of conservation
concrete operational stage
child is able to carry out mental operations, de-centre, carry out concrete logical thinking
