1. Perception Organizational Theories

2. Perceptional Organization
Our perceptive brain has the ability to construct stimuli in a way that makes sense
We may look at the edges of an object or colors to make that determination
Without this ability, all stimuli would be the same

3. Processes within Perceptional Organization
There are multiple methods that the brain uses to organize our perception
These are usually logically based on what we are trying to perceive

4. Figure Ground Organization
Your sense of perception has a filter
By using figure ground organization, it can filter out what is not important within a complex environment
It can also focus in on what is important

6. Organization by Grouping
Our sense of perception will automatically place things together that belong together.
It looks for similarities and organizes pieces into wholes (even if they’re not there)
These organizational characteristics are divided into 2 schools
-Gestalt Laws
-Palmer’s Laws

7. Gestalt Laws: Proximity Similarity Continuity Closure Common Fate 1 23 4 5

8. Who’s Going Up/Down???

9. Palmer’s Laws:
Synchrony
Common Region
Connectedness 1 2 3

10. What does this say???

11. Auditory Scene Analysis
When we hear things, they are not just sounds
According to Auditory Scene Analysis, we create a mental image of what we think we hear
This helps us to better perceive the stimuli we are receiving

12. Two-Dimensional Location
Since not everything is right in front of use, we must use our body to sense things around us
According to this theory, when we sense something that is not directly in front of us, our brain must interpret how we are sensing it
EXAMPLE: we hear a sound to our right and turn our head to the right to see what made the sound. Just because the source of the stimulus is right in front of our eyes does not mean we will assume that the object is right in front of us.

13. Depth Perception
When we see an object, we must be able to tell if the object is right in front of us or further away
This is very important because we need to be able to judge how far away things are in proximity to use, how fast they are moving, etc…

14. Depth Perception:

15. Size Constancy
Our brain will attempt to create things as they should be, based on their size
If we view an object from far away, such as a building, it may look small. Our brain, however, will take into account the distance and adjust accordingly

16. Shape Constancy
Even if a shape changes within our perception, we will still be able to tell what it is
We have the innate ability to realize what we are looking at even if we view from a weird angle

17. Draw the bottom of the picture???

18. Draw the bottom of the picture???

19. Brightness Constancy
An entire part of our perception abilities deal with the differences between hues and brightness
This is why we can usually tell the difference between one color and another
This is also why we can tell if one thing is brighter or darker than another

20. Which Grey Square is Darker???

21. Which Grey Square is Darker???

22. Motion Based Perception
We have the ability to determine in which direction an object is moving and where it is moving to
We can also make a relative estimate of how fast or slow the object is moving
As objects move, we must also move in accordance to those objects
Using our depth perception, we can tell when an object is getting closer or moving away based on its size
-We call this looming

23. Looming Danger???:

24. Culture, Experience, and Perception
Much of how we perceive the world is based on our cultural experiences
Culture is not just our ethnic culture, but also our family culture
Our experiences will also help us perceive things differently
Part of this is developmental, but another part is experiential
If you have experienced something before, then you will be able to tell what it is the next time you perceive it.
