PS102 - MIDTERM 2 Flashcards
1
Q
Encoding
A
Getting information into memory in the first place
2
Q
Information-Processing Model
A
View of memory suggesting that information moves among three memory stores during encoding, storage, and retrieval
- Info must pass through three stages: Sensory, working, and long-term memory
3
Q
Sensory Memory
A
Memory involving a detailed, brief sensory image or sound retained for brief period of time
- Holds everything we see, hear, taste, touch, and smell for a few seconds of less
- Allows us to decide if we should pay futher attention to the stimuli
4
Q
Working Memory (Short-term)
A
A short-term memory store that can hold five to nine items at once
- Info will eventually drop out of working memory and disappear or will be futher passed on to our long-term memory
5
Q
Long-Term Memory
A
The memory system in which we hold all th einfo we have previously gathered, available for retrival and use in a new situation or task
- System that can retain a seemingly unlimited number of pieces of info for an indefinate period of time
6
Q
Parallel Distributed-Processing (PDP) Model
A
Theory of memory suggesting that information is represented in the brain as a pattern of activation across entire neural networks
7
Q
Automatic Processing
A
Encoding of information with little conscious awareness or effort
8
Q
Effortful Processing
A
Encoding of information through careful attention and conscious effort
9
Q

A
Continuous repitition of info in an attempt to make sure the info is encoded
10
Q
Spaced Practice Effect
A
Facilitated encoding of material through rehearsal situations spead out over time
11
Q
Phonological Code
A
Encoding based on sound
- Trying to keep an address in mind to put into the GPS by repeating the sounds of the numbers again and again
12
Q
Visual Code
A
Encoding based on vision
- Trying to keep and address in mind to put into the GPS by holding an image of how the digits would look if written down
13
Q

Cognitive representation of info or an event based on the meaning of the info
- This means we lin the new things we learn to the things we have already memorized based on shared meaning
14
Q

23
Q
Retrival Cues
A
Words, sights, or other stimuli that remind us of the info we need to retrieve from our memory
24
Q
Priming
A
Activiation of one piece of info, which in turn leads to activation of another piece and ultimately to the retrival of a specific memeory
25
Recognition Tasks
Memory tasks in which people are asked to identify whether or not they have seen a particular item before
- Multiple Choice
26
Recall Tasks
Memory tasks in which people are asked to produce info using no or few retrival cues
27
Context
The original location where you first learned a concept or idea, rich with retrieval cues that will make it more likely you will be able to recall that information later if you are in that same location or contex
28
Encoding Specificity Principle
A theoretical framework that asserts that memory retrieval is more efficient when the information available at retrieval is similar to the information available at the time of encoding
29
State-Dependent Memory

30
Flashbulb Memories
Detailed and near-permanent memories of an emotionally significant event, or of the circumstances surrounding the moment we learned about the event
31
Decay Theory
Theory of forgetting, suggesting that memories dafe over time due to neglect or failure to access over long periods of time
32
Interference Theory
Theory that forgetting is influenced by what happens to people before or after they take info in
33
Proactive Theory
Competing info that is learned before the forgotten material, preventing its subsequent recall

34
Retroactive Interference
Learning of new info that distrupts access to previously recalled info

Repression
Process in which we unconsciously prevent some traumatic events from entering our awareness so that we do not have to experience the anxiety or blows to our self-concept that the memories would bring
36
Source Misattributions
