Perceptions Flashcards
Function fusiform area of the brain?
Recognizes faces
What is depth perception?
our ability to know what is close and what is far. Thus, ability to see in 3D.
Why do we need depth cues?
Our retina is a flat surface. We need depth cues so our brain can see in 3D.
What is interposition?
one object partially block another
What is the relative size?
larger objects are perceived as being closer.
What is Linear perspective?
parallel lines are the same distance but appear closer as they are closer.
What is texture gradient?
More details when objects are closer.
What is a shadow?
Cast by an object
What is a motion parallax?
objects that are close seem to move faster.
What is binocular disparity and how does it help us with our depth perception?
the difference between the information perceived by our two eyes.
As brain merges the two visions: it knows that the bigger the disparity the closer the objects are.
What is subliminal messaging? What are its effects?
The way we perceive info without being conscious of it.
It is weak and temporary.
What is top-down processing?
our processing is influenced by expectations, prior knowledge and beliefs.
What is inattentional blindness?
Fail to see important info because focused on something else.
Explain the study for inattentional blindness?
People had to go up to the counter and get a pack with the info for the study.
The person behind the counter bent down so the participant couldn’t see them, and switched with someone else.
The participant usually didn’t notice the change
What is distorting cognitive illusion?
