- Introduction
- Complex visual scene
- Selective attention (1)
- Selective attention (2)
- What is the 'fate' of the unattended information?
- Investigations
- Spatial cueing of attention
- Goal-directed cueing: valid and invalid trial
- Goal-directed cueing: neutral trial
- Stimulus-driven cueing: valid and invalid trial
- Spatial attention facilitates detection
- Cortical regions related to visuospatial attention
- Lesion to parietal cortex (such as after a stroke)
- Example: Federico Fellini
- Example: Anton Raderscheidt
- Patients with parietal lesions
- Vision and eye movements
- Location and duration of fixations
- Neglect: errors and eye movements
- Normal: no errors in reading
- Hemianopic: no reading errors
- Neglect in visual imagery (1)
- Neglect in visual imagery (2)
- Neglect in visual imagery (3)
- Influenced by probability? (1)
- Procedure
- Influenced by probability? (2)
- Enhanced RT without awareness
- Speeded RTs without awareness
