Developmental psychology (1) Flashcards
Development of a foetus' brain, functions of the parts of the brain, twins, influences on development - info from L1 and L2 ppts
At what stage in pregnancy does brain development begin?
3rd week
What happens during the 4th week of pregnancy regarding brain development?
The neural tube begins to divide into the spinal cord, forebrain, midbrain and hindbrain
What happens at week 6 of pregnancy regarding brain development?
The forebrain divides into two areas- they go onto develop the thalamus and cortex.
Neurons and synapses begin to develop in the spinal cord.
What happens at week 15 of pregnancy regarding brain development?
The cerebellum has formed from the hindbrain.
What happens at 6 months of pregnancy regarding brain development?
The brain is fully formed, but doesn’t reach its full size for a while
What is the frontal lobe responsible for?
Cognitive abilities like thinking, planning and problem solving
What is the temporal lobe responsible for?
Contains the auditory cortex, that’s responsible for processing sound.
What is the parietal lobe responsible for?
Processing sensory information like touch, heat and pain.
What is the occipital lobe responsible for?
Contains the visual cortex, which processes visual information from our eyes- makes sense of images during perception.
What is the brain stem responsible for?
Basic functions like breathing, digestion and your heart beating.
What is the cerebellum responsible for?
Can you give an example?
Coordination of movement, balance, motor learning and reflex memory.
EG: used during dance
What is the thalamus responsible for?
Sends messages from senses to the cortex
define nature
Behaviors and traits caused naturally
(genes, hormones, brain structure)
define nurture
Traits and behaviors caused by the environment
(friends, culture, socialisation)
IQ, height and weight are all examples of [nature/nurture/both].
(pick one)
IQ, height and weight are all examples of both nature and nurture.
What are dizygotic twins?
“non-identical” twins - share 50% DNA - two separate eggs during conception
Remember: Di - two - two eggs
What are monozygotic twins?
“identical” twins - share 100% DNA - one egg split into two
remember: mono - one - one egg
Give 3 influences on development in the womb.
- alcohol and caffeine consumption of the mother
- the mother smoking - nicotine slows down brain development
- the mother coming into contact with the rubella virus/german measles- it can lead to brain damage
How do we know that babies recognise their mothers’ voices immediately after birth?
When a tape was played of the mother’s voice, the baby sucked more on a special device compared to when a tape of someone’s else’s voice was played.
(DeCasper and Spence)
What’s the independent variable?
The variable you change/alter
What’s the dependent variable?
The variable you measure
What’s the control variable?
The variable that is kept the same
What issues might a damaged cortex cause?
Speech issues
(add more later using textbook)
What issues might a damaged brain stem cause?
death, paralysis, motor issues
