The 20 questions
-
What chemical imbalance is linked to depression in the biological explanation?
- Serotonin
- Adrenaline
- Melatonin
- Insulin
-
What type of chemical is serotonin in the brain?
- Enzyme
- Antibody
- Hormone
- Neurotransmitter
-
What process reabsorbs neurotransmitters back into the presynaptic neuron after release?
- Excitation
- Transmission
- Inhibition
- Reuptake
-
Is the biological explanation of depression based on nature or nurture?
- Social
- Nature
- Nurture
- Environmental
-
According to the biological explanation, serotonin levels in depression are usually what?
- Abnormally high
- Completely absent
- Abnormally low
- Fluctuating rapidly
-
What is the expected outcome of antidepressant drugs that increase serotonin availability?
- Improved mood
- Increased anxiety
- Reduced heart rate
- Memory loss
-
How does rapid reuptake affect serotonin levels in the synaptic gap?
- Increases serotonin
- Reduces serotonin
- Has no effect
- Doubles serotonin
-
Which factor is considered a nature influence on depression?
- Neurotransmitter imbalance
- Life events
- Family environment
- Negative thoughts
-
What does a purely biological explanation of depression ignore?
- Psychological factors
- Synaptic transmission
- Genetics
- Brain chemistry
-
Which brain scan technique can measure chemical activity in the brain?
- EEG scan
- PET scan
- CT scan
- MRI scan
-
What type of relationship is shown when low serotonin levels are found alongside depression?
- Experimentation
- Generalisation
- Causation
- Correlation
-
What do drug trials directly test in biological explanations of depression?
- Childhood trauma
- Gene mapping
- Serotonin level changes
- Negative schema changes
-
What type of chemical messenger carries signals across a synapse between neurons?
- Hormone
- Neurotransmitter
- Axon
- Receptor
-
According to biological explanations, what is the main effect of a neurotransmitter imbalance?
- Altered mood
- Negative attributions
- Unconscious conflict
- Faulty schemas
-
What process describes the reabsorption of serotonin by the presynaptic neuron after signal transmission?
- Summation
- Synaptic transmission
- Excitation
- Reuptake
-
Why is explaining depression using only neurotransmitters described as reductionist?
- Ignores brain structure
- Relies on self-reports
- Lacks empirical evidence
- Simplifies complex behaviour
-
Which factor represents the nature side of the biological explanation for depression?
- Life events
- Learned helplessness
- Inherited genetics
- Negative schemas
-
Why do researchers study the timing of neurotransmitter changes during depressive episodes?
- To cure depression
- To change genetics
- To establish cause
- To measure schemas
-
How do biological treatments like SSRIs aim to relieve depression symptoms?
- Desensitising phobias
- Replacing negative schemas
- Changing attributions
- Increasing serotonin availability
-
What primary factor does the biological explanation for depression focus on compared to psychological explanations?
- Cognitive schemas
- Environmental triggers
- Attributional styles
- Brain chemistry
