And here's your shmoop du jour brought to you by proximity

00:06

exploited by annoying little brothers on long car trips everywhere. [Young brother annoying sister on car trip]

00:12

Alright, here's today's question Jen sees the legs of the chair the seat and the

00:16

putrid mauve color of the cushion she realizes it is a chair this is an

00:21

example of what and here are your potential answers.

00:26

alright putrid mauve, where Jen go to find this chair the 1970s alright so [Woman balancing chair in her mouth]

00:31

this question is asking us to identify Jen's thought process about this gross

00:35

chair so let's jump right in is this an example of D) Gestalt rules well Gestalt

00:40

rules are also known as the principles of grouping a set of

00:44

principles in psychology that suggests that humans naturally perceive objects [Balloons, presents and peppers]

00:49

as organized patterns these principles are organized into six categories

00:54

similarity we see things that are similar as part of the same group

00:58

closure the mind tendency to complete figures even if they aren't actually [Person completing jigsaw]

01:02

complete continuity if objects intersect we can perceive the separate object as

01:08

uninterrupted. Common fate - if things are moving together we typically group them together

01:14

Good form - our ability to identify common shared attributes like form pattern or color in [monkey playing with different shapes]

01:19

order to group objects together and finally proximity objects that are

01:24

closer together are often grouped together and also answer E) Ok so let's catch our [Man wipes sweat from forehead]

01:29

breath and we're back because all this refers to grouping and not at all the

01:34

singular object perception so we can lose D) and E) right away hey group wrong

01:39

answers how appropriate alright it's Jens thought process and example of C)

01:44

figure ground processing, well figure ground processing is the ability to

01:49

identify a figure from the background this could mean identifying a bird in [Boy points to bird in the sky]

01:54

the sky words on a page or trying to figure out this super famous optical

01:58

illustration by Edgar Ruben you know the one you'd see their two faces or a vase

02:02

depending on how you look at it well personally we think it looks like a [Optical image of two faces with a vase in the middle]

02:05

goblet but that's not even one of the options so thanks Ruben, anyway seeing

02:09

this question doesn't refer to the ability to distinguish the chair from a

02:12

background this doesn't fit either, so you can cross

02:14

out C) so that leaves us with top-down processing and bottom-up processing well

02:20

top-down processing is when we take our expectations and knowledge to help us

02:24

interpret sensory stimuli let's say Jen just spent an afternoon listening to her [Jen laid on grass listening to music]

02:29

favorite song on repeat and her favorite song just happens to be about the

02:34

one-eyed one-horned flying purple people eater well if she were to walk into a [Purple people eater appears]

02:39

room shortly thereafter only to find a mauve chair lurking in the shadows

02:43

top-down processing might cause her to assume the sofa was in fact a hungry [Chair attempts to eat woman]

02:48

hungry monster bottom-up processing on the other hand refers to the ability to

02:53

pick up features of stimuli in our world and piece them together to make

02:56

sense of them you know like seeing the legs and seat of the chair and

03:00

rationally coming to the conclusion then it's just an ugly fuzzy chair and if [An ugly chair appears]

03:04

that' sounds familiar good thinking is exactly what the question describes so B)

03:08

is our answer so honestly you don't need to listen to classic Halloween songs to

03:13

be scared of this putrid mauve monstrosity [Putrid mauve chair appears in a room]
