The genetic explanation would argue that OCD is due to the inheritance of what? | one or many maladaptive genes e.g. SERT |
Which maladaptive gene has been shown to explain OCD? | A mutation in the SERT gene |
The genetic explanation would suggest that the closer the genetic link, the greater risk of? | Risk of inheriting OCD |
What is the key term used to explain a natural risk to developing a disorder based on your genetic makeup? | genetic predisposition |
Genetic probability of sharing behaviour behaviour is measured by? | concordance rates |
If there was a higher concordance rate, what does that mean for the genetic basis of behaviour? | There is stronger evidence for a genetic basis of behaviour. |
Which scientific research methods are used when studying how our biology affects behaviour? | • Gene mapping • Brain scans - fMRI’s, EEG’s |
Which type of twins have a greater probability of sharing a behaviour? | Monozygotic |
In Carey and Gottsman’s twin study research into OCD, what percentage concordance rates did monozygotic twins have for OCD? | 87% |
In Carey and Gottsman’s twin study research into OCD, what percentage concordance rates did dizygotic twins have for OCD? | 47% |
Define genotype (2 marks) | A specific set of genes that an individual has inherited from their biological parents and is unique to them (their genetic makeup). Genotypes can give a predisposition to disorders. |
Define phenotype (2 marks) | The product of what happens when the genotype interacts with the environment. This is how our genes are expressed through physical, behaviour and psychological characteristics. They are observable traits/shown through behaviours. |
Specific set of genes that are inherited from biological parents and is unique to an individual (their genetic makeup) is known as? | genotype |
The product of your genotype interacting with the environment / the expression of our genes through observable behaviours is known as? | phenotype |
Identical twins have the same genotype - true or false? | True |
Identical twins always have the same phenotype - true or false? | False |
What is a biological structure in our body? | The brain or a system such as the nervous system or the endocrine system which can influence how we behave. |
Abnormalities in brain anatomy can lead to certain behaviours. In what 3 ways may our brain change to become abnormal? | • change in: • Size • Shape • Function |
How has the brain been linked to an increased likelihood of experiencing symptoms of Schizophrenia (SZ)? | Enlarged ventricles in the brain have been linked to increased likelihood of symptoms in SZ. |
Organs such as the brain and systems such as the nervous and endocrine system are all what? | Biological structures |
