Transmission
Processing

30
Q

What is important for experience and action to happen?

A

Perception
Recognition
Action

31
Q

What is bottom up?

A

Start with the info from our sensory receptors and builds up to a final product in our brain
-start with details and work our way up

32
Q

What is top down?

A

Start with larger concept or idea and works down to the details

33
Q

What kind of organization is perception and sensation?

A

Sensation is Bottom up

Perception is top down

34
Q

What is Gestalt psych?

Top down

Predictable ways in which we organize sensory info into meaningful pattern that we perceive

35
Q

What are the different kinds of Gestalt psych?

A 
Figure Ground segregation
Closure
Proximity
Continuity
Similarity

36
Q

What is attention?

A

Lets us focus in on one small stimuli from our world and channels out other information so we can focus on the other parts

37
Q

What is the Broadbent filter model of selective attention?

A

Stimuli passes through filters to enter into our attention

-and if we dont pay attention it filters out and decays

38
Q

What is the Treisman attention model of selective attention?

A

Can carry on a conversation in a room full of conversations but can be distracted by hearing your name in another context
-cocktail party effect

39
Q

What does the ability to multitask depend on?

A

Task stimulating
Task difficulty
Task Practice
-can also be called divided attention

40
Q

What is schema?

A

Mental framework that allows us to organize our experiences/stimulus

41
Q

What do you have to do to use schema effectively?

A

To use effectively must constantly assimilate new experiences, new information is interpreted based on our current situation

As we interact with the world we accommodate schema to incorporate new information and experiences

42
Q

What are the Piaget stages?

A

Sensorimotor 0-1.5/2
Pre-operational 2-6/7
Concrete Operational 7-11
