00:07

life a little less rough. we know that joke tickled your funny bone [woman playing with a dog]

00:11

here's the question..Mary sees the dog as separate from the bone it is chewing

00:15

which of the following explains what she sees and here are your potential answers....

00:20

Our brains are pretty cool think about it they help us [People at a beach with brains for heads]

00:27

interpret and understand all the visual stimuli in the world quickly and

00:30

accurately so instead of being visually overwhelmed all the time we can focus on

00:34

the more important things in life like a test prep, see what we did there alright let's [Girl preparing for a test]

00:39

get started could Mary's brain be engaging in A) bottom-up processing well

00:44

bottom-up processing describes our ability to pick up various features of

00:47

stimuli and put them together to make sense of them we see fur, four legs

00:51

floppy ears and voila we know that what we're looking at is a sweet little pup [puppy in the street]

00:55

but if we happen to have seen a lost werewolf poster in the area recently

01:00

well then maybe we'd perceive this innocent and playful dog as a dangerous [puppy transforms into a beast]

01:05

beast this would be top-down processing which describes when we take our

01:09

knowledge and expectations to help interpret our sensory stimuli neither of

01:13

these however have to do with distinguishing the dog from her bone so

01:16

we can cross out A) and B) what about D) shape constancy well this concept

01:21

refers to our ability to perceive the shape of a given object as constant [shape constancy definition]

01:26

despite our view angle changing so if we look at the dog from this angle and then [Woman looking at a dog]

01:32

this angle our brain knows that the shape hasn't changed but that our

01:36

perspective or angle has, it's a way of contextualizing the object and our

01:41

perceptions in order to make sense of our surroundings similarly if we were to [Dog sitting down]

01:45

view the dog in this light and then this light our mind understands that the

01:50

object itself isn't becoming more or less bright but instead that the light [Dog surrounded by colorful lighting]

01:55

around it is changing well both of these constancy's allow us to make sense of

01:59

the world in a simple way or otherwise the constant growing and shrinking and [Magician makes woman grow and shrink]

02:03

color changing would make us wonder if we fell down a rabbit hole but neither are

02:08

our answers that must mean that Mary's perception can be described by [Mary thinking]

02:13

C) figure ground relationship when discussing the ability to discern

02:17

between objects we're talking about figure ground relationship first [Dog chewing a toy]

02:21

explained by Gestalt psychologists it describes how we automatically perceive

02:26

an object as a separate entity from its surroundings the figure cute little pup

02:30

here is the center of our attention so we're able to perceive it as separate [Puppy dog carrying a bone in its mouth]

02:35

from the background and in turn the bone so C) is the correct answer that was

02:39

the best test prep video ever right right come on now throw a dog a bone
