Brain and Nervous System
This lobe of the brain processes visual information.
What is the occipital lobe?
The three stages of memory are…
What are encoding, storage, retrieval?
What type of design uses the same people in both conditions?
What is repeated measures?
This ethical principle means people choose freely to participate.
What is voluntary participation?
The most common score in a data set.
What is the mode?
These two structures connect the left and right hemispheres of the brain.
What is the corpus callosum?
This type of memory stores information briefly but can transfer it if meaningful.
What is short-term memory?
What is the difference between an independent variable and a dependent variable in an experiment?
The IV is what the researcher changes; the DV is what is measured.
This principle means participants are not identifiable.
What is confidentiality?
The middle score in an ordered list.
What is the median?
This part of the nervous system controls internal organs automatically.
What is the autonomic nervous system?
This is the term for memory improved by being in the same environment.
What is context-dependent memory?
A researcher wants to test if music affects memory. Group A studies with music, Group B studies in silence. What type of research design is this?
What is independent groups?
The right to leave a study at any time.
What is withdrawal rights?
This shows how likely the results occurred by chance.
What is the p-value?
This neurotransmitter is linked to memory loss and Alzheimer’s disease.
What is acetylcholine?
Two brain areas involved in memory storage.
What are the hippocampus and cerebral cortex?
What is the main advantage of using a repeated measures design instead of an independent groups design in a psychology experiment?
It controls for individual differences because the same participants are used in all conditions.
A sports psychologist conducts a study with members of their own sports club. What ethical concerns might arise in this situation?
Possible issues include conflict of interest, pressure to participate, or lack of voluntary participation.
What does a p-value of 0.01 mean?
It shows how likely the results are due to chance. p = 0.01 means there is a 1% chance the results are random, so it is statistically significant.
Compare the functions of the temporal and parietal lobes.
Temporal = hearing/language; Parietal = sensory processing
Describe two features of neuroplasticity.
brain can reorganise after damage; it changes with experience
A psychologist wants to know if watching videos or reading instructions leads to better learning of a skill. What would be an appropriate research hypothesis for this experiment?
Example: “Participants who watch videos will perform the skill more accurately than those who only read instructions.”
Name all five key ethical principles used in psychological research.
Voluntary participation, informed consent, confidentiality, withdrawal rights, debriefing
A set of memory test scores is: 11, 13, 13, 16, 18, 19, 21, 25.
• What is the mean of this data set?
Mean = 17
