Approaches - Ao1+Ao3 Flashcards
Ao1 - Assumptions of Biological Approach
Biological app suggests that all behaviour is determned by our biology - eg genes and hormones
One assumption is 1859 Charles Darwin make origin of species - keywords - natural selection, evolution, adaptive characteristics
Genetics - Genes are genetic information carried by DNA in chromosomes - 23 pairs or 46 individual - Genes can determine behaviour ,and therefore allows for a** disposition** to certain behaviours - eg MAOA, CDH13, XYY
always link back to how genes can determine behaviour
Behaviour is determined by our biology, give 2 examples.
Genetics: MAOA Gene - Links to Aggression
CDH13 - links to addiction
XYY also
Who made the Origin of Species and when
Charles Darwin 1859
Keywords involved in Darwins theory
Natural selection - the process in which species evolve over time as their offspring retains the preferential adaptive characteristics more suited for survival.
What are genes?
Genes are genetic information carried by DNA in chromosomes (23 pairs or 46 individual)
How many pairs/individual chromosomes does a typical human have?
(23 pairs or 46 individual)
What can genes determine and give an example.
Genes can determine behaviour - eg. MAOA CDH13 or XYY
What is genotype and phenotype?
Genotype is the genetic configuration of an indvidual
Phenotype describes the observable characteristics of an individual as a result of the combined effects of genetic makeup and surrounding evnrionment on behaviour.
What does nature/nurture argue?
It argues for the extent as to which our behaviour is determined by biological factors over environmental factors and vice versa.
Ao3 of biological Approach
positive : Real life applications via drug treatments eg SSRI’s in OCD, Antipsychotics for SZ, Antidepressants for depression.
positive : the biological approach is grounded in the science of biology as it produces objective evidence that is often irrefutable, investigatong cause and efect directly eg PET and fMRI
negatives: Labratory experiments lack ecological validity, the findings may not reflect the nature of real life scenarios for example loftus and palmer (1975) didnt factor in the effect of anxiety on recall, decreasing the generalisability and external validity.
negatives: Sample type - use of idiographic samples in bilogical approach through case studies in memeory via Clive Wearing the entire existence of samanti, procdural and epsidoc memories hinges from the findingd of one atypical man are generalised to the whole populus.
What are the positives of the biological approach?
Real life applications - investigations into how our biology impacts our behaviour lead to drug treamtnets such as antidepressants, antipsychotics, SSRI’s for OCD.

Negatives of Biological Approach
Lack of ecological validity - lab experiements means that it may not reflect the nature of a real life scenario, and therefore cannot be generalisable to the whole population. For example, loftus and palmer (1975) which didnt counter in stress and therefore reduced their external validity
Sample type - idogrphaic sample emans that they reduce their generalisability through case studies being generalised to the whole pupulation.
What are the real life applications of the biological approach?
Positive 1
Drug Treatments - eg antipsychotics antidepressants SSRI’s.
How is the biological appraoch scientific?
It is grounded in the science of biology, it is objective and irrefutable and investigates cause and effect directly, eg PET and fMRI.
How do lab experiments affect the Biological Approach?
Lack of ecological validity - it becomes arguable as to wether the findings reflect the real life scenario, decreasing the generalisability of the study. For example, Loftus and Palmer (1975) didnt factor in anxiety on encoding, and therefore reduce their external validity.
How does sample size impact the biological approach?
Idiographic sample - case studies in biological resarch mean that it is generalising findings from one individual to a widwr population eg clive wearing and semantic, epsiodic and procedural memory.
Ao1 of Behaviourist Approach
p1 - Behavioural approach revolves around the ide of conicitoing via stimulus and response or punishment and reward. For example, Pavlov (1897) where there was the bell (NS) and the food (UCS) which resulted int he bell being CS and slivating being the UCR.
Skinner rats - skinner made the skinner box where a rat would step on a switch to get food, and therfore woud continue to do that, and were punished if it did not. 3 types of condictioning ,positive reinforcemnt - giving a reward, negative reinforcement - taking away something bad and punishement - giving a consequence for non-preferential behaviour.
What was the process of pavlov
FIRST there was the bell (NS) along with the food (UCS), which caused salivation, the UCR.
SECOND this was repeated as the dog begun to associate the NS with the UCR.
THIRD the food was taken away, and the bell became the CS with the salivating now being the CR.
What was the process of skinner
The rats would eplore the box until they accidentally stepped on a switch, giving them food, positively reinforcing them to proess it again. If it went too long without pressing the switch, the rat would be shocked. If the rat pressed it again, it would gain the Positive reinforcement of the food and the Negative reinforcement of no shocks.
Ao3 of Behaviourist
+ Behaviourism is scientific - it was the first psychology to study cause and effect, giving the subject scientific discipline and advancing it as a whole. Not only does this increase the validity of the studies however also attracted more funding and research opportunities in the subject.
+ Real world applications - for example phobias and systematic desnsititisations helps people
- Animal studies - based on assumption that humans are like aimals, also raises ethical issues since nimals in skinner were shocked and harmed.
- Ignores role of cognition and mediational processes, focsues only on behavioural aspects an ignores emotional and cognitive aspects
How is behaviourism scientific?
How did this aid psychology as a whole?
Behaviourism is scientific because it used a lab based cause and effect study. This made advances in calling spychology a science and gave it scietific disipline, allowing for more funding and research opportunities.
What are the real world applications for behaviourist approach?
Phobias and systematic desensitisation.
What are the nagatives of using animal studies in the behaviouralist approach?
Depends on the assumption that animals behave like humans which is false, an also raises ethical assies in the protection of the animals as the rats were shocked and harmed.
What is the problem with the behavioural approach only focusing on behavioural aspects of behaviour?
The problem is that it ignores emotional and cognitive aspects, not acknoweldging that there may be other mediational processes that can impact behaviour.
