brain learning and motivation: intro to biological psychology and the brain Flashcards
Descartes
philosopher and defender of dualism
proposed:are humans merely physical machines? physical things?
he answered nno with two arguments in favour of dualism
Descartes arguments for dualism
1 humans can do things machines could never do e.g. mechanical duck by Jacques de Vaucanson (1737) the duck mimicked eating and defecting but couldn’t decide what it ate but humans can
2 he used doubt and discovered people are not really sure of anything
dualsim
dualism is the theory that the mental and the physical—or mind and body or mind and brain—are, in some sense, radically different kinds of thing.
if you put your brain in soeone else’s body would it still b you
levels of analasys from molecules to memories
to understand who we are, we need to understand the mechanisms of our brains. Our consciousness cannot exist outside our brain. We are just a specific assembly of nerve cells and their associative compounds
we are the sum of our experiences and those are stored in a neural structure unique to each individual
said by crick THE ASTONISHING HYPOTHESIS (1994)
idea that the ind is what the brain does, this idea is favoured more by scientists than dualism
individual brain differences
allbrains have differences structurally even siblings
alziemers age and alcohol effects on the brain
people with theses have many large vacuoles in the brain and their braindoesnt quite fill the skull
biopsychological approach
human and non human subjects
Quasiexperimental research
case studies
pure and applied research
biopsychology: pisiological psychology
study of the neural mechanisms of behavior by manipula1ng the nervous systems of nonhuman animals in
controlled experiments.
psychopharmacology
study of drugs and their affect on brain and behaviour
Neuropsychology
study the psychological effects of brain damage in human pa1ents.
psychophisiology
study of the rela1on between physiological ac1vity and psychological processes in human subjects by non invasive physiological recording.
cognative neuroscience
study of the neural mechanisms of human cogni1on, largely through the use of func1onal brain imaging.
comparative psychology
study of the evolu1on, gene1cs and adap1veness of behavior largely through the use of the compara1ve
method.
physiological psycologists: researching memory would…
use hypocampal lesion patients such as HM
or make hypothetical lessons using techniques preciously discussed
psychopharmacologists: when studying memory would…
investigate Neurochemistry of Alzheimer’s disease – the
role of acetylcholine in memory
neuropsychologists: when studying memory would…
alcohol-produced brain damage: Korsakoff’s syndrome
phsychophysiologists: when studying memory would…
erp’s of familiar faces compared to unfamiliar faces
cognative neuroscientists: when studying memory would…
imaging successfully and unsuccessfully stored
informa1on
comparative psychologists: when studying memory would…
birds cache seeds- hippocampal size
cognitiave psychologists: when studying memory would…
investigate schemas and memory
socialpsychologists: when investigating memory would…
investigate stereotype threat and its effect on exam results
developmental psychologists: when investigating memory would…
investigat infantile amnesia
counselling psychologists: when investigating memory would..
investigate intrusively into traumatic memories and PTSD
applied psychologists: wen investigating memory would…
look a facial recognition and witnesses
invertaspectrum problem
woman sees red when man sees blue due to different pattern of neural firing so she has a different experience of these colours than him
…these differences are communicated through language
the astonishing hypothesis…
Our minds would not exist without neurones, their interac1ons, the chemicals that bind them together
proof:
there is strong evidence that the brain is involved in mental life
nervous system
divided into:
central nervous system
peripheral nervous system
central nervous system
made up of:
brain
spinal cord
periforal nervous system
everything outside brain and spinal cordmade up of:
somatic nervous system
autonomic nervous system
periforal nervous system: somatic nervous system
control of getting messages to and from brain includes: skin muscle joints
made up of sensory and motor neurone signals
all send signals to spinal cord and brain
spinal cord and brain also send signals to these areas
periforal nervous system: autonomic nervous system
sends and receives information to and from
include:
Glands
internal organs
from brain and spinal cord and vice versa
autonomic nervous system
part of system that sends information is further divided into:
sympathetic nervous system
para-sympathetic nervous system
both maintain balance of homeostasis
autonomic nervous system: sympathetic nervous system
activates processes e.g. fight or flight response
sends signals to different parts of body
eg dialates pupil
autonomic nervous system: para-sympathetic nervous system
sends signals to different parts of body to calm down so opposite of sympathetic
eg constricts pupil
central nervous system: spinal cord
densely packed bundle of nerve fibres
relay station between body and brain
connects most parts of peripheral system with brain
control of fast reactions without conscious though
eg hand in fire
transfers information from and to sensory and motor neurons
structure of the brain
the brain is made up of 3 main sections:
the forebrain
the midbrain
the hindbrain
structure of the brain: the forebrain
where most of the thinking happens made up of:
Thalamus
Hypothalamus
Cerebrum (including cerebral cortex on both hemispheres)
Limbic system
corpus callosm
structure of the brain: the hindbrain
oldest part of the brain made up of: the cerebellum Pons Medulla Oblongata ...controld vital movements eg heart
