Biological Psychology – Spatial Memory
What is spatial memory?
Answer:
Spatial memory is the ability to remember the location of objects, places, and routes within the environment. It allows individuals to navigate, recognise landmarks, and remember the spatial relationships between different locations.
Research shows that the hippocampus plays a major role in spatial memory.
How does the hippocampus contribute to spatial memory?
Answer:
The hippocampus is essential for remembering spatial locations.
Evidence shows that:
What are place cells?
Answer:
Place cells are specialised neurons located in the hippocampus.
They:
What did Maguire et al. (1998) discover about the hippocampus?
Answer:
Maguire et al. (1998) found that activation of the right hippocampus was associated with:
What did Maguire et al. (2000) discover about London taxi drivers?
Answer:
Maguire et al. (2000) studied experienced London taxi drivers.
The researchers found that:
What limitation should be considered when interpreting the taxi driver study?
Answer:
Although experienced taxi drivers have larger posterior hippocampi, cause and effect cannot be established.
It is unclear whether:
What are the roles of the rhinal cortex and hippocampus in memory?
Answer:
Current evidence suggests that different brain regions have specialised roles.

Brain Regions Involved
Conclusion
Spatial memory is primarily mediated by the hippocampus, which enables individuals to remember locations, navigate environments, and understand the spatial relationships between objects. Evidence from lesion studies, place cells, and the research of Maguire et al. (1998) and Maguire et al. (2000) supports the important role of the hippocampus in navigation and spatial memory. However, the taxi driver research cannot determine cause and effect, as it remains unclear whether a larger hippocampus leads to better spatial memory or whether extensive navigation experience produces structural changes through brain plasticity. Current evidence also suggests that the rhinal cortex is responsible for object recognition, while the hippocampus specialises in remembering the spatial relationships between objects, highlighting the complementary roles of these brain regions in memory.

Research shows that the hippocampus plays a major role in spatial memory.
How does the hippocampus contribute to spatial memory?
Answer:
The hippocampus is essential for remembering spatial locations.
Evidence shows that:
- Damage (lesions) to the hippocampus impairs memory for spatial locations.
- Individuals with hippocampal damage often have difficulty navigating familiar environments.
What are place cells?
Answer:
Place cells are specialised neurons located in the hippocampus.
They:
- Become active only when an individual is in a specific location.
- Help create an internal “cognitive map” of the environment.
- Support navigation and spatial memory.
What did Maguire et al. (1998) discover about the hippocampus?
Answer:
Maguire et al. (1998) found that activation of the right hippocampus was associated with:
- Knowing where places are located.
- Successfully navigating towards those locations.
What did Maguire et al. (2000) discover about London taxi drivers?
Answer:
Maguire et al. (2000) studied experienced London taxi drivers.
The researchers found that:
- Taxi drivers with 20 years or more of experience had significantly more grey matter in the posterior hippocampus than the general population.
What limitation should be considered when interpreting the taxi driver study?
Answer:
Although experienced taxi drivers have larger posterior hippocampi, cause and effect cannot be established.
It is unclear whether:
- A larger hippocampus improves spatial memory, allowing individuals to become successful taxi drivers, or
- Years of navigation experience cause the hippocampus to grow through brain plasticity.
What are the roles of the rhinal cortex and hippocampus in memory?
Answer:
Current evidence suggests that different brain regions have specialised roles.
Rhinal Cortex
- Responsible for object recognition.
- Identifies and recognises objects.
- Responsible for remembering the spatial relationships between objects.
- Supports navigation and spatial memory.
What is the current understanding of spatial memory?
Answer:
The current consensus is that:
- The rhinal cortex processes object recognition.
- The hippocampus processes spatial relationships between objects and locations.
What are the key findings on spatial memory?
Answer (Note Form):
Hippocampus
- Essential for spatial memory.
- Damage (lesions) impairs memory for spatial locations.
- Supports navigation.
Place Cells
- Specialised neurons in the hippocampus.
- Activated only in specific locations.
- Form cognitive maps of the environment.
Maguire et al. (1998)
- Right hippocampus activated during:
- Navigation.
- Remembering locations.
Maguire et al. (2000)
- London taxi drivers (20+ years’ experience):
- Larger posterior hippocampal grey matter.
- Suggests relationship between navigation and hippocampal structure.
Limitation
- Cause and effect cannot be established.
- Larger hippocampus may:
- Improve spatial memory, or
- Develop because of extensive navigation experience.
Brain Regions Involved
- Rhinal cortex
- Object recognition.
- Hippocampus
- Spatial relationships between objects.
- Navigation.
- Spatial memory.
