BIOLOGICAL APPROACH:ASSUMPTIONS + RELATIONSHIP FORMATION Flashcards
ASSUMPTIONS + RELATIONSHIP FORMATION
define the first assumption of the biological approach.
The first assumption of the biological approach is evolutionary influences.
the first strand of this is evolution. what is evolution?
This proposes that the human mind+ behaviour has
1. evolved over millions of years
2. to adapt to demands of individual environments,
what is this based on?
based on Darwin’s theory of natural selection (1847)
what is natural selection?
This is the idea that
-genetically determined behaviour
which enhances an individual’s chance of survival and reproduction
- will be naturally selected,
- and the genes will be passed onto the next generation.
the inherited genes are the ___ approach?
This is the nativist approach,
what is it believed to account for?
- and is believed to account for variance in a species,
- as different families inherit different genes.
the second strand is environment of evolutionary adaptiveness (EEA). what is this?
- Furthermore, a key concept of the evolutionary approach is the environment of evolutionary adaptiveness;
- the environment and selective pressures at the time the species adapted.
what does this assume?
It is assumed that only the forms of behaviour that ensure survival within a particular environment are adaptive.
give an example of naturally selected behaviour.
- For example, altruistic behaviour would be selected in this theory,
- as it is an adaptive trait that enhances survival of the gene pool.
give a real-life example that explains physiology linked to evolutionary theory.
- Namely humans having large brains relative to their body size;
- it has evolved responding to the complex social organisation of man.
how is this adaptive - why was it naturally selected?
Humans with greater interpersonal skills are increasingly likely to survive
1. as they are better adapted to the social structure and dynamic environment,
2. granting them a selective advantage over those who do not.
what is the selective advantage paradigm known as?
This is survival of the fittest.
define the second assumption of the biological approach.
1.The second assumption is the localisation of brain function,
2. asserting that certain areas of the brain are responsible for different functions.
what region contains the lobes? what is its function?
- The cerebral cortex is functionalised for higher order cognitive function,
- and is divided into four lobes:
what are the four lobes?
frontal
parietal,
temporal,
and occipital,
each with specific functions.
function of frontal lobe
frontal lobes are involved in
thinking
and creativity,
and have been linked to personalities.
function of parietal lobe
parietal lobes
receive sensory information,
three examples of this sensory information.
- like temperature,
2.touch - and pain.
function of temporal lobe
temporal lobes are
1responsible for memory
2 and auditory information processing.
function of occipital lobe
occipital lobes are concerned with
1visual processing
2and receive information directly from the eyes.
give an example from psychology.
1) Additionally, there are specific areas of the brain linked to the processing of language.
2) Wernicke’s area is in the posterior portion of the left temporal lobe.
this is eponymous of whom?
1)Carl Wernicke, a German neurologist,
2) discovered another area of the brain involved in understanding language.
3)His patients could speak but were unable to understand language.
define the third assumption of the biological approach.
The third assumption of the biological approach is neurotransmitters.
what is the basis of the nervous system?
1)Neurons are electrically excitable cells that form the basis of the nervous system.
2)The flexibility of the nervous system is enhanced by having many branches at the end of each neuron called dendrites,
3)connecting neurons to many others.
