When presented with superimposed images of a house and a face, Mack is asked to focus on the house. This attentional "focus" results in

Simons and Chabris showed a video of students passing a basketball and asked participants to count how many passes made. In the video, a person in a gorilla suit walked through the basketball players for 5 seconds. Approximately how many of the participants reported seeing the "gorilla"?

The ability to perceive a rod as being continuous behind an occluding block

Posner's precueing studies demonstrated that attention

The finding that attention can spread within an object, thereby, enhancing detection at other places within the object is referred to as

"Learning from past experience" as a factor involved in attention was demonstrated by Shinoda et al. (2001), who showed that drivers are more likely to detect stop signs when they were positioned

In the "I'm a Believer" scene at the end of the movie "Shrek," the three blind mice are turned into the horses in one frame, but the next time we see them, they are dancing on a piano as mice. This is an example of __________, which can be a "real-life" example of _________ if you do not notice the switch.

_____________ is when a stimulus that is not attended is not perceived, even though the person is looking directly at the stimulus.
