Cognitive Psychology use four main Research Methods
1)- Laboratory Experiments - Very scientific and reliable as it is possible to have great control over variables in a lab. It has low Ecological Validity - doesn't tell us much about the real world.
2)- Field Experiments - Take place in a natural situation (e.g studies of memory or attention in school environment), so they have more Ecological Validity, but there's less control of other variables.
3)- Natural Experiments - Involve making observations of a naturally occuring situation. Little control over the variables and participants cant be randomly assigned to conditions. High Ecological Validity. Not massivly reliable.
4)- Brain Imaging - Can now be carried out during a cognitive task. For example, MRI scans have been used to show the blood flow in different brain areas for different types of memory tasks.
