What is the main purpose of creating models in the context of human performance?
What is the main purpose of creating models in the context of human performance?
- To capture essential pieces and allow a closer look at phenomena (correct)
- To underfit the model by excluding essential components for simplicity
- To limit the model to only what it needs, without any additional components
- To overfit the model with unnecessary components for a detailed analysis

How is light processed in the human visual system?
How is light processed in the human visual system?
- It is captured by the optic nerves and then focused on the retina before being processed in the brain
- It directly goes to the brain for processing without being focused on the retina
- It passes through the lens and is focused on the retina before being processed in the brain (correct)
- It is captured by the retina and directly sent to the brain for processing
