lifespan psychology Flashcards
three types of development?
continuous, discontinuous and sequential
describe continuous development
a cumulative process that involves gradually improving skills over life.
describe discontinuous development
takes place in unique stages that occur at specific times throughout life
describe sequential development
begins with simple thoughts, feelings and behaviours. they eventually progress to be more complex over time.
describe how quantitative data can be measured
amount of words in vocab, height, weight
describe how qualitative data can be measured
changes in the quality/type of speaking/movements
what are the two research methods?
longitudinal and cross-sectional
explain cross-sectional studies and advantages/disadvantages
they research multiple groups of people at varying ages at one point in their life. advantage is it takes less time, disadvantage is it does not control extraneous variables
explain longitudinal studies and advantages/disadvantages
longitudinal studies follow the same individuals over a period of time and observe changes as they grow older. advantages is extraneous variables stay the same so can be controlled/considered. disadvantage is it takes time.
what are hereditary factors?
hereditary factors are biological factors that can influence development
give an example of a hereditary factor
gene vulnerability. increased likelihood of developing disorders or conditions due to genes
what are environmental factors? give examples
external factors that influence development. home life, way we were raised, culture.
what is an enriched environment?
enriched environment are when all basic needs such as love and nutrition are met. good exposure to necessary stimuli
what is a deprived environment?
basic needs aren’t met, impaired development
how do twin/adoption studies look at the difference between hereditary and environmental factors.
-identical and fraternal twins compare how genes impact development (hereditary)
- adoption looks at how environmental factors impact development
why is attachment important for emotional development?
attachment is innate. it gives an infant a sense of security and allows them to feel like they have someone to depend on and have a safe haven.
what are the three types of attachment?
- secure attachment
- anxious avoidant
- anxious resistant
