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]
