The Cognitive Approach
-
The role of schema
-
-
-
Schema enables us to process lots of information quickly, a mental short-cut that stops us from becoming overwhelmed by our environment.
-
Cognitive Neuroscience
-
Advances in brain imaging techniques such as fMRI and PET scans, scientists can now systematically observe the neurological basis of mental processes.
Research involving tasks that required the use of episodic and semantic memory, scientists used to show how the different types of long-term memory may be located on different sides of the pre-frontal cortex.
Cognitive neuroscience has expanded due to the use of computer-generated models that can 'read' the brain.

Limitations
Machine reductionism
-
-
E.g. human memory may be affected by emotional factors, such as anxiety on eyewitnesses.
Application
-
Experiments are carried out using artificial stimuli that may not represent everyday memory. Lacks EXTERNAL VALIDITY.
