COGNITIVE PROCESSES (MEMORY) - Memory & Chemical Messengers
20 important questions on COGNITIVE PROCESSES (MEMORY) - Memory & Chemical Messengers
What is the behavioural measure used in the Arena task, and what are the control variables (CV)?
- Behavioural: Spatial memory performance in the Arena task (finding the pole).
- CV:
- Double blind procedure.
- Random allocation to initial condition.
- Screen went black for 30 seconds, after learning where the pole was located on the VR Map.
Why is acetylcholine (ACh) a naturally occurring agonist?
Describe the sample used in the study.
- 20 healthy right handed male adults, mean age: 28 years old.
- Small sample size.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What design was used in the study to eliminate participant variability?
What evidence was found regarding error rates with scopolamine?
What was the aim of Antonova et al (2011)?
What did some participants express during the debriefing?
In the Antonova (2011) study, what is the name of the antagonist and what does it do?
What are the areas of uncertainty in the study?
- Uncertainty of how strongly scopolamine blocks the receptor sites.
- Some participants reported feeling stressed by the injection or fMRI environment.
Describe the sample and procedure used in Antonova et al (2011).
In the study, what does it show the role acetylcholine in the hippocampus to be?
What assumptions and biases are noted in the study?
- Possible sampling bias: All male participants.
- Stress from injections and fMRI could change hippocampal activation and memory encoding.
- Limited researcher bias: well controlled by the blind design.
