25
the process by which the brain interprets and organizes the chaos that bombards our senses, is formed and how it affects our memories.
Perception
26
refers to thinking (reasoning & problem solving)
Cognition
27
Three types of Reasoning
1. Deductive 2. Inductive 3. Abductive
28
Problem-Solving examples
1. Gestalt (based on experience) 2. Problem space theory (Probability) 3. Analogy
29
(visual) persistence of the image after the stimulus has been removed
Iconic
30
(aural) allows a brief “play back”
Echoic
31
touch
Haptic
32
Smell and Taste
33
4 types of Sensory Memory
1. Iconic 2. Echoic 3. Haptic 4. Smell and Taste
34
* Scratch-pad for temporary recall * Used for information needed fleetingly * Rapid access, limited capacity * Patterns were used for memory aids
Short Term Memory
35
Information held in LTM is not represented as patterns of neural activity but rather as changes in brain wiring neurons
Long Term Memory
36
Long Term Memory (Capacity)
virtually unlimited
37
Long-Term Memory (Duration)
up to lifetime
38
Long-Term Memory (Processing)
Processing: information is organized according to meaning and associatively linked.
39
amount learned is proportional to amount of time spent
Total Time Hypothesis
40
Information must be meaningful for it to be
stored
41
old replaced by new or vice versa
Interference
42
new information replaces the old
Retroactive Interference
43
the old memory interferes with the new information
Proactive Inhibition
44
the info has been seen before
Recognition
45
reproduced from memory
Recall
46
Mental faculty that allows us to communicate
Language
47
little to none shallow
novice
48
little to none shallow
first time
49
some, but not specific
knowledgeable intermittent

True
53
This reasoning is the way of arriving at generalizations from observations we have seen about cases we have not seen.
Inductive Reasoning
54
Last Song Syndrome
Short Term Memory
55
Articulation is where the user communicates the task in the input language.
True
56
Changing your focus from one point to another creates movement. This movement is called scanpath.
saccades
57
Knowing your user is just a piece of cake. It is easy as 1, 2, 3.

HCI always considers the sense of taste in designing systems.
False
62
It pertains to the understanding of the real-world activities or tasks that the user interface aims to accomplish.
Domain Knowledge
63
According to Allen Newell, user proficiency profile shows us how knowledgeable the users in the interface and domain.
