unit 1 - human lifespan development Flashcards
define ‘growth’
an increase in a measurable quality such as weight, height or head circumference
define ‘development’
a complex change including skills & abilities and capabilities
define ‘gross motor skills’
involves movements of large muscles such as arms, legs, hand & feet
define ‘fine motor skills’
this the smaller more refined movements things such as fingers, toes
what age is infancy & early childhood?
infancy - 0-2
early childhood - 3-8
what is the ages for adolescence & early adulthood?
adolescence - 9-18
early adulthood - 19-45
what is the ages for middle adulthood and later adulthood?
middle adulthood - 45-65
later adulthood - 65+
what are the physical development for 19-45 years (early adulthood)
brain wave patterns are more mature patterns
young adults have reached full height and strength
towards the end of the stage adults may start to lose speed and strength
what’s the role of hormones in females & what are these hormones?
the two hormones in females are oestrogen & progesterone
the ovaries produce these which are responsible for changes in ovulation & menstruation
what is it the main role of hormones in male & what is this hormone called?
this hormone is called testosterone
the testes start to produce testosterone which stimulates sperm production
testosterone is also responsible for development of secondary sexual characteristics
what’s the role of hormones in sexual maturity?
sex hormones are responsible for the changes that occur in puberty
the release of hormones from the pituitary glands controls the onset and rate of puberty (physical changes e.g. hair)
name some of the primary sexual characteristics in males
penis enlarges
testes begin to produce sperm
the prostate glands produces secretion
name some of the secondary sexual characteristics for males?
hair growth on armpits
facial hair growth
voice breaks
name some primary sexual characteristics in females?
oestrogen - maintaining your uterus
ovaries begin to release eggs
the menstrual cycle commences
name some secondary sexual characteristics for females?
oily skin
wider hips
breast development
hair grows
define ‘lactation’
the secretion of milk from the mammary gland
define prolactin & oxytocin?
prolactin stimulates the production of milk
oxytocin stimulates the flow of milk
what happens in the perimenopause?
the level of oestrogen rises and falls unevenly, your menstrual cycles may lengthen or shorten, and you may begin having menstrual cycles in which your ovaries don’t release an egg (ovulate)
with 12 consecutive months without a menstrual period, you’ve reached menopause
symptoms of perimenopause?
hot flushes and night sweats breast tenderness loss of libido (lower sex drive) fatigue irregular or very heavy periods vaginal dryness, discomfort during sex mood swings trouble sleeping urine leakage when coughing or sneezing urinary urgency (an urgent need to urinate more frequently)
state the physical development which happens in middle adulthood?
aging speeds up during middle adulthood (ages 40–65) and there is a decline in vision, hearing, and immune-system functioning
round the age of 60, the eyes lose their ability to adjust to objects at varying distances
most people between the ages of 40 and 60 will need some form of corrective lenses for vision deficits
middle-aged adults are also at higher risk than younger adults for certain eye problem, such as glaucoma
state the physical development which happens in later adulthood?
during late adulthood the skin continues to lose elasticity, reaction time slows further, muscle strength and mobility diminishes, hearing and vision decline, and the immune system weakens
when menopause happens there is a decrease of oestrogen, explain what this does to the body?
bones break down more easier and the bones are less dense
name the five aspects of intellectual development and what they are?
language development - essential for organising thoughts & to share ideas
problem solving - a skill which is required to work things out & make prediction of what might happen
memory - it stores, recalls and retrieves information
moral development - informs you how to act towards others and yourself and allows for reasoning and making choices
abstract thoughts & creative thinking - essential for thinking & discussing situations/events that can not be observed
intellectual milestones from 3-8
age 3 - ask questions, count recognise colours
age 5 - starting to read & write & draw in detail, can talk about past and future
age 8 - can think more deeply, reason, talk about abstract ideas and plans
intellectual development in middle adulthood?
can think through problems and make sounds, judgments using life experiences
intellectual development for later adulthood?
changes in the brain can cause short term memory decline and slower thought processes and reaction times
what is a schema?
a category of knowledge as well as the process of acquiring knowledge
an example of a schema is - Jack has developed a schema for a cow. He knows that a cow is large, has four legs and a tail
when he sees a horse he might initially call it a cow as it fits with his schema of a large animal
once Jack has been told that the horse is a different animal, he will modify his existing schema for a cow and create a new schema for a horse.
four processes of schema?
adaptation - the overall process of adjusting behaviours to cope with the environment
assimilation - when a child perceives new objects or events in terms of existing schemas
disequilibrium/Accommodation - when a child tries to interpret something new with an old schema, they often get it wrong and so get confused, this is known as disequilibrium, they are forced to change your old schema/create a new schema to cope with this new information.
Equilibrium - a balance between assimilation and accommodation-being able to respond effectively in a variety of different situations
state the two assumptions of the piaget’s stage theory?
progress through the stages is in a fixed order
the abilities in each stage have to be achieved in before the child can progress to the next level
what is the 0-2 stage called and what is it?
the sensorimotor - where infants know the world through movements and sensations
basic actions so as sucking, grasping, looking and listening
what study is used for 0-2 year olds?
piaget (1963) blanket and ball study
piaget tested object permanence by taking a toy from the child and hiding it under a blanket.
before 8 months of age, infants would not reach for the hidden toy
infants over 8 months would search for the toy, showing that they had object permanence
piaget concluded that object permanence develops around 8 months
what is the stage for 2-7 year olds?
the pre- operational stage - children begin to think symbolically and learn to use words and pictures to represent objects
tend to be egocentric
what is the study used for 2-7 year olds?
three mountains task -
showed 4-12 year-olds a model of 3 mountains, a person was sat on the other side of the model.
from the other side of the model the child had to choose the view that the person would be able to see
children aged 4-5 years chose their own view but by 7-8 years they could choose the correct view
piaget concluded that pre-operational children cannot decentre: they are egocentric
what is the 7-11 stage called?
concrete operational
during this stage, children begin to thinking logically about concrete events
they begin to understand the concept of conservation; that the amount of liquid in a short, wide cup is equal to that in a tall, skinny glass
their thinking becomes more logical and organized, but still very concrete
what is the study used for 7-11 year olds called?
conservation of number -
by having a tall, long glass filled with water and a small wide glass filled with water the children should be able to realise that they have the same amount in but just different sizes
what is the 12-18 stage called?
formal operational
at this stage, the adolescent or young adult begins to think abstractly and reason about hypothetical problems
teens begin to think more about moral, philosophical, ethical, social, and political issues that require theoretical and abstract reasoning
begin to use deductive logic, or reasoning from a general principle to specific information
what is the study for 12-18 year olds called?
pendulum task
the method involved a length of string and a set of weights
participants had to consider three factors (variables) the length of the string, the heaviness of the weight and the strength of push
the task was to work out which factor was most important in determining the speed of swing of the pendulum
participants can vary the length of the pendulum string, and vary the weight, they can measure the pendulum speed by counting the number of swings per minute.
to find the correct answer the participant has to grasp the idea of the experimental method - that is to vary one variable at a time (e.g. trying different lengths with the same weight)
piaget concluded that the systematic approach indicated the children were thinking logically, in the abstract, and could see the relationships between things, these are the characteristics of the formal operational stage.
state some of the criticisms of piaget?
small number of children in his study
piaget suggest that the age/stages he describes may be more fluid than he thought and that he underestimated and overestimated children’s cognitive abilities
studies show at 5 years old they do understand others feelings and are far less egocentric than Piaget suggested
bruner did not agree with Piaget’s notion of fixed stages and ‘readiness’ to learn. He believes that, with adult support, children can be helped to progress to higher level thinking skills
other research suggests that children take longer than 11 years to become skilled at abstract logical thinking
state what Bower and Wishart (1972) experiment is?
Bower and Wishart showed 20 week old babies a toy dangling from a string.
they then turned out the lights and found that all the infants continued to reach for an object in the dark
the finding suggest that Piaget underestimated children’s capabilities because his methods were limited. Their reactions depend on how the object disappears.
