lifespan development Flashcards
what is growth?
growth is an increase in measurable quantities e.g. height, weight
principles of growth
growth rates are not constant, different parts of the body grow at different rates, growth rates tend to vary between children and the growth rate of boys is usually faster on average than that of girls, as men tend to be taller than woman
measuring height
infants grown rapidly and will reach roughly half their adult height by the age of two, adolescents experience growth spurts during puberty and full height is reached by the start of early adulthood
head dimensions
head circumference is measured at birth and at 6-8 weeks to identify any abnormality in brain or skull growth, skull growth is faster in the 1st two years of life but continues into early adulthood. head circumferences is measured across the forehead, just above the ears and at the midpoint of the back and the head
recording growth
growth is an indicator of children’s health and wellbeing, measurements are plotted on a growth chart. centile lines represent the values of measurement from a a large number of children to show ‘norms’ of growth in each age group. growth charts give the length or height, weight and head dimensions expected at a particular age, comparing children’s growth against norms is important to identify signs of ill health and development problems, growth charts are different for both boys and girls as their expected rate of growth varies.
what is development?
acquiring skills and abilities in an orderly sequence, head to toe, inside and out
what are the 4 areas of development?
physical, intellectual, emotional and social
physical development
growth and other physical changes that happen to our body throughout life
intellectual/cognitive development
the development if language, memory and thinking skills
emotional development
the ability to cope with feelings about ourselves and towards others
social development
the ability to form friendships and relationships, and to learn to be independent
developmental milestones
the rate of development may vary between individuals but it follows the same sequence, with each stage called a milestone (developmental norm), development is observed and cannot be measured in the same way as growth
what are gross motor skills?
they allow children to control the large muscles in their torso, arms, legs, hands and feet.
gross motor skills in infancy
infancy develop their gross motor skills from the head down, around six months, infants gradually control muscles in their neck an back so they can roll, sit and crawl. at around 11-13 months, the muscles in their legs develop so that they can stand, cruise and walk. at around 2 years, infants can climb onto low furniture and propel a sit on toy, and at 2 and half yrs they can kick a ball.
gross motor activity
crawling, walking, running, balancing, coordinating, bending, climbing, pulling, pushing, kicking, scooting, jumping, skipping
3-4 ; gross motor skills
- they can pedal and control a bicycle
- they can hope on one foot
- they can throw a ball and they can aim it
- they can run forwards and backwards
- they can balance and walk along a line
5-8 ; gross motor skills
- they can ride a bicycle
- they can hop, skip and jump with confidence
- they can accurately throw and catch a ball
- they can skip with a rope
- they can balance on a low beam
what is fine motor skills?
they are important in controlling and coordinating movement of the small muscles in the fingers and hands
fine motor skills & development
- newborns - able to grasp an adult’s finger
- 3 months - hold a rattle for a short amount of time
- 6 months - grasp a toy and pass it to his other hand
- 12 months - l pick up small objects using a pincer grip
- 18 months - build blocks and use spoon and make marks with crayons using a palmar grasp
- 2 yrs - will be able to shoes on and control crayon to draw circles and dots
- 3 yrs - developing tripod grasp, can use fork and spoon, turn the pages of a book, button and unbutton clothing
- 4 yrs - will be able to thread small beads and color in pictures
- 5 yrs - control muscles in fingers to manipulate the block and use hand eye coordination to fit the piece into the correct place, can write own name forming letters correctly
- 8 yrs - can use joined up handwriting
activities that support fine motor skills
- gripping is where they have the strength in fingers and hands to hold an object firmly; activities: holding a rattle, tricycle handle or spoon
- manipulation is where they have the skillful movement of objects using fingers and hands, such as tuning, twisting and passing objects from one hand to another; activities: building with block, playing a musical instrument, playing with and placing farm animals or cars
- hand eye coordination is the control of eye movement at the same time as finger and hand movement; activities: writing, sewing or completing jigsaw puzzles
what are the stages of development?
infancy - 0-2
early childhood - 3-8
adolescence - 9-18
early adulthood - 19-45
middle adulthood - 46-65
later adulthood - 65+
puberty (adolescence)
during adolescence, young people experience a physical change during puberty, this takes place in girls around 11-years and in boys around 13-years. puberty starts when a hormone in the brain sends a signal to the pituitary gland, which releases hormones that stimulate the ovaries in girls and the testes in boys to produce sex hormones. during this stage, a young persons height can increase rapidly over a short time - this is known as a growth spurt.
the role of hormone in sexual development
boys - the hormone testosterone is produced by the testes. stimulates growth of the penis and testes, pubic hair growth, the development of muscle and lowering of the voice.
girls - the hormones estrogen and progesterone are produced by the ovaries. they stimulate the growth of breasts and reproductive system and help to regulate the menstrual cycle.
primary sexual characteristics
these are the processes that are related to the sex organs that are present at birth and mature when sex hormones are released.
girls:
- menstruation begins
- uterus and vagina grow
- ovulation occurs
boys:
- penis enlargens
- prostate gland produces secretions
- testes enlarge and produce sperm
secondary sexual characteristics
these are not necessary for reproduction. they develop when sex hormones are released.
girls:
- growth of armpit and pubic hair
- increased layers of fat under the skin
- breasts enlarge
- growth spurt
- hips widen
boys:
- growth of facial hair
- growth of armpit, chest and pubic hair
- increased muscle
- growth spurt
- larynx grows, causing voice to deepen
maturation (early adulthood)
- motor coordination is at its peak
- physical strength and stamina is at its peak
- full height is reached
- reaction time is quickest
- women are at their most fertile and can become pregnant and lactate
- hand eye coordination is at its peak
- sexual characteristics are fully developed
fertility and perimenopause (early adulthood)
at the beginning of this life stage, women are at their most fertile. around 40-45 years old, they reach the end of their reproductive years. this period is called the perimenopause.
- estrogen decreases
- menstruation becomes less frequent
- ovulation is regular
during menopause, the reduction in estrogen causes physical and emotional symptoms that include:
- hot flushes
- night sweats
- mood swings
- loss of libido
- vaginal dryness
ageing (middle adulthood)
signs:
- greying hair
- loss of muscle tone, strength and stamina
- body shape may change with an increase in or loss of weight
- men begin to lose hair
- women are no longer fertile as menstruation ends
- loss of height
the role of sex hormones in females
- estrogen plays the most important role in female sexuality and regulates ovulation
- progesterone is necessary for the implantation of fertilized eggs in the uterus, the maintenance of pregnancy and sexual health
symptoms of menopause = hormonal changes
reduction in estrogen causes:
- the ovaries to stop producing eggs
- thinning and shrinkage of the vagina
- affects the hypothalamus in the brain, which regulates temperature, causing hot flushes and night sweats
- affects the health of hair, skin and nails
- may cause mood swings, as estrogen regulates neurotransmitters that affect mood
reduction in estrogen and progesterone:
- gradually stops menstruation
- impacts libido
effects of ageing ; later adulthood
physical:
- less elasticity in the skin
- decline in strength
- loss of muscle
- loss of stamina
- less mobility in the large muscles in arms, legs and torso (gross motor skills)
- less mobility in the small muscles of the hands and fingers (fine motor skills)
- reduction in vision
- reduction in hearing
- thinning of hair on the head and pubic areas
- decline in the performance of organs
- higher susceptibility to disease and infection
- increased likelihood of injuries caused by falls
- height loss, it is caused by changes in posture and compression of the spinal discs and joints
intellectual:
ageing does not always impact on cognitive ability, but it can negatively affect how individuals process information, eg:
- memory
- recall
- speed of thinking
what is intellectual development?
intellectual development is about how individuals organise ideas and make sense of the world around them
types of intellectual development
problem solving - needed to work things out and make predictions about what might happen
language development - essential to organise and express thoughts
memory - essential for storing and recalling information
abstract thought and creative thinking - essential for thinking and discussing things that can’t be observed
moral development - needed for reasoning and making choices about how to act towards self and others
stages of life
intellectual development continues in early adulthood, by early adulthood individuals have gained knowledge, skills and experience. they use past experiences to make judgements. thinking is logical and realistic. individuals are able to think through problems and make decisions.
infancy and early childhood - this is a time of rapid intellectual development.. 90% of neuron connections are in place by the time children are 5 years old.
early/middle to later adulthood - individuals continue to learn new skills and knowledge into later adulthood, intelligence does not change but short term memory and thinking speed may decline.
intellectual milestones
- from birth; can use all their senses to help understand the world around them.
- at 3 years ; can ask questions, count, recognise colours and sort objects.
- at 5 years; starting to read and write and draw in detail, can talk about the past and the future
- at 8 years; can think more deeply, reason, talk about abstract ideas and plan
piaget - cognitive development
piaget believed that children pass through distinct developmental stages in sequence, he thought that children should be allowed to discover things for themselves through spontaneous play.
the four stages are:
sensorimotor (0-2)
pre operational (2-7)
concrete operational (7-11)
formal operational (11-18)
sensorimotor
- from birth to 2 years
infants learn about their environment and develop early schemas (concepts) by using all their senses to physically explore the world
pre operational
- from 2 to 7 years
children begin to control their environment by using symbolic behaviour, including representational words and drawings and pretend play, but are not yet able to think logically
concrete operational
- from 7 to 11 years
children use practical resources to help them understand the world, such as counters for mathematics. they classify, categorise and use logic to understand things they see
formal operational
- from 11 to 18 years
young people have the capacity for abstract thought, rational thought and problem solving
criticisms of his development theory
some critics believe that piaget underestimated children’s development and that with support they can move more quickly to the next stage of development
piaget’s schema theory
this theory explains how children use their experiences to construct their understanding of the world around them
the stages consist of :
- assimilation
- equilibrium
- disequilibrium
- accommodation
schema breakdown
assimilation - the child constructs an understanding or concept (schema) ; the child has developed a schema about sand
equilibrium - the child’s experience fits in with their schema ; the child’s experience in the nursery sandpit fits with their schema
disequilibrium - a new experience disturbs the child’s schema ; water is added to the sandpit, the sand behaves differently which upsets the child’s schema
accommodation - the child’s understanding changes to take account of the new experience; the child changes their schema to accommodate their new experience of sand. they develop a schema.
piaget - conservation
piaget carried out tests to show the stage hen children begin to reason and think logically
- the child is 4, he is shown two identical glasses with the sane amount of water in each
- the water from another glass is poured into a tall, narrow beaker
- the child believes that the tall, narrow beaker contains more water
conservation refers to children’s understanding that the amount remains the same even when the container’s shape has changed. piaget also used tests using solids, weight and number.
what does piaget’s test show?
- children under 7 years old cannot conserve because they cannot think about more than one aspect of a situation at one time
- by the operational stage, children can think logically so understand that the quantity of water stays the same when poured into a differently shaped container.
conservation & egocentrism
- conservation refers to the children’s understanding that the amount remains the same even when the container’s shape has changed. piaget also used tests using solids, weight and number.
- egocentrism is based on the fact that piaget believed that, until children are 7 years old, they only see things from their own perspective, he used his swiss mountain test to prove his theory of egocentrism
criticisms of piaget
- piaget sometimes underestimated children’s rate of development
- with support, children can develop more advanced concepts
- children can be given experiences that help them to move through the stages at a faster rate
- some children can see things from the perspective of others before the age 7
what is language development?
language development involves communication through articulation and receptive speech.
stages of language development
infancy :
0-3 months:
- make mouth movements in response to parent
- cries to ask for food or comfort
6-12 months:
- understands some words, such as ‘byebye’
- makes sounds such as ‘gaga’
18 months:
- can say between six and ten words
- can follow simple instructions
early childhood:
2-3 years:
- links words together, for example, ‘me car’
- vocabulary increasing to approximately 200 words at 2 and a half yrs
3-5 years:
- uses simple sentences
- asks questions
- may use incorrect forms of words, for example ‘i good’
8 years:
- speaks in complex sentences
- can reason and explain
adolescence:
9-19 years:
- developing vocabulary
- uses language to explore abstract ideas
chomsky
chomsky proposed the LAD (language acquisition device) as the hypothetical part of the human mind that allows infants to acquire and produce language.
he suggested that humans are:
- born with a structure in their brain that enables them to acquire language
- have a critical period for first language development in the first years of life
- all follow the same pattern of language development
- have an innate understanding of the structure of language (called universal grammar) that is the basis for all languages (subject, verb, object)
criticisms of chomsky
- lack of scientific evidence of innate understanding of structure of language
- the rate of language development is affected by the degree of interactions with others
- does not take into account that a language acquisition support system is required
- chomsky put emphasis on grammar in sentence development rather than meanings
theories of attachment
an attachment is an emotional bond that is formed between infants and young children and their main caregiver
