Final answer:
Spatial cognition is the ability to perceive and navigate in physical space. Two tasks that test spatial cognition are praxis and gnosis.
Step-by-step explanation:
Spatial cognition refers to the ability to perceive, understand, and navigate in physical space. It involves mental processes such as spatial awareness, spatial memory, and mental rotation. Two tasks that test spatial cognition include:
- Praxis: This task involves performing a motor task based on verbal instructions without any demonstration. For example, a patient may be instructed to flip their hand palm-up and repeat the action multiple times.
- Gnosis: This task assesses the ability to recognize objects through touch alone. For example, a patient may be asked to identify an object placed in their hand without looking at it.
