Attention and Object Recognition

1) How do neural representations of objects differ when the subject is versus is not attending to the object?

2) How does the brain process and represent multiple visual objects?

Perceptual Awareness

1) How do neural representations of objects differ when we are aware of them and when we are not?

2) What are the neural necessary conditions for perceptual awareness? For example, what if anything is the role of top-down feedback in perceptual awareness?

3) What are the processing consequences of perceptual awareness?
