Question 4

(lecture):

The job of the visual system is not merely to record (like a camera as mentioned in the first lectures) what’s out there but to capture what’s out there. To do so we need to focus on certain parts of the image. It appears there is so much information out there that it is impossible to comprehend everything at once. So what you think you can see at the moment, you can’t. Everybody thinks they can see everything all at once, you can actually only see a tiny little bit at a time and the rest is not really there, you can create it tho when you shift your attention to that little bit.

Key concepts:

• COVERT paradigm
• Exogenous and endogenous cues
• Change blindness
• Object vs. space selection
