Human Development Flashcards
What are the different approaches that have been used to study human psychological development
Social development (attachment theory)=at least one primary caregiver is critical to personal development Cognitive development (language) = information processing, conceptual ressources, perceptual skill, language learning and other aspects of the developed adult brain Emotional development (loneliness in old age)
Nature vs nurture?
Nature- the hereditary information present at the moment of conception that may affect later development
Nurture- all the external elements that may influence development
Stability- individuals who are high or low in a characteristic will remain so at later stages (emphasis on nature)
Early experiences= powerful events in the first few years that cannot be fully overcome in later years (emphasis on nurture)
Plasticity= change is possible and likely if new experiences support it
What is continuous growth?
E.g. Plant growth
What is discontinuous growth?
Butterfly development
Why are ethics important in psychology?
The principle of freedom from harm should underlie all psychological research and practice
Psychological research findings are open to misinterpretation and may not be used in ways originally intended
Is it sufficient to have parental approval for children under 16?
What are the implications of children not having these rights
Why are children considered a vulnerable group?
Inevitably perceived if not real power imbalance between the child and the researcher (conservation tasks)
Abilities comprehend research and why it is done may be very different to adults
It is reasonable to be cautiously concerned that negative experiences during childhood may have an effect on later development
Define ageing
The evolution of sexual reproduction (Williams 1957)
The accumulation of changes in a human being over time, physical, encompassing physical, psychological and social change. E.g. Reaction times slow with age (Bowen 2004)
Ageing is the greatest known risk factor for most human diseases, 150,000 people who die each day across the globe, about two thirds die from age related causes (Dillin 2014)
How can we study cognitive ageing?
Cognitive psychology of ageing investigated the effects of ageing on behavioural measures of cognition and characterised a variety of age-related deficits in memory, attention, language and so on
Neuroscience of ageing investigated the effects of ageing on the anatomy and physiology of the brain and described forms of age related neural decline, such as cerebral atrophy
-cognitive neuroscience of ageing= relationships are still wildly unknown
What does the psychometric approach analyse?
Relations among test scores
Sample size is large (100s)
What does the experimental cognitive approach analyse?
Efficiency of processes/strategies involved in task
Small sample size (2 groups of less than 50)
What does the neuropsychological approach analyse?
Efficiency of brain structures
Tests specific to some brain regions
Very small to medium sample size (1 to less than 50)
What does the cognitive neuroscience approach analyse?
Involvement or brain structures in task processes
Measure of brain activation during task performance
Very small sample size of 2 groups just over 30
What does the epidemiological approach analyse?
Coarse changes in representative samples
Very large sample size of 100s to 1000s
Brief tests in general cognitive abilities
How to define healthy/unhealthy ageing?
Associated with several structural, chemical and functional changes in the brain as well as a host to neurocognitive changes
Structural changes= loss of neural circuits and brain plasticity, thinning of the cortex, dna damage
Chemical changes= alterations in neurotransmitters and their receptors (e.g. Dopamine)
Neuropsychological changes= changes in orientation, attention, memory, language
What are the important features of early social and emotional development?
If the relationship between young children and attachment figures is disrupted it could lead to the child developing psychological difficulties
Freud= child’s main drive is to feed, mother is the source of food, mother is associated with food
Bowlby(1907-1990)= children who spent long periods of time in hospitals showed serious developmental problems (Robertson and Robertson 1940s) but he argued that the cause of these problems were the lack of close emotional bond between child and primary care giver
