Term
Short Term Memory (STM)
Definition
the temporary storage of small amounts of information over a short amount of time (usually a few seconds)

It is only part of a larger system of memory and also includes the working memory
Term
Short Term Storage (STS)
Definition
acts as a working memory responsible for selecting and operating strategies, rehearsal, and working as a global workspace

Problem: this idea it would guarantee learning since it goes straight to LTM, which isn't the case
Term
Long-term memory (LTM)
Definition
a system which is able to store large amounts of info over a long period of time (memory stored over time)

It is an interaction between:
1. amount of rehearsal
2. type of rehearsal
3. Whats already in LTM
Term
Working Memory (WM)
Definition
stores and manipulated info for better understanding "a work bench system"
-language processing
-logic and reasoning
-problem solving
Term
Echoic Memory
Definition
Sound version of flash memory, lasts longer that visual memories

ex. white noise study
Term
Iconic Memory
Definition
specific to visual sensory memory, can hold about 4 items (at first this was thought but through sperling's ex 2 h discovered it was unlimited but fades meaning it is only limited by time), role of attention

ex. glowing ember in 1740
Term
Double Disassociation
Definition
two groups of pateint have reverse conditions:
1 damaged STM but fine LTM
2 Damaged LTM but fine STM

Cannot conclude the other is not working until you find someone to oppositely compare it to

~A = B
~B = A
Term
World length Effect
Definition
it is easier to study short words than long words b/c you are able to do more loops in your head to remember them and thus you forget less
Term
Chaining
Definition
a memory technique in which every piece of info is related to what precedes and follows it, we know this is not a real technique people ppl are able to still remember chunks of info in the beginning and end even if they do not in the middle
Term
Primacy
Definition
recalling the first few items in a sequence better than the rest since they are rehearsed more
Term
Recency Effect
Definition
Tendency to remember the last few items in a sequence b/c they are fresh in STM
Term
Free Recall
Definition
a task in which the participant is asked to remember as many items as possible and recall them in any order they wish
Term
Serial Recall
Definition
A task in which participants must recall the items the order that the info was given to them
Term
Chunking
Definition
A memory technique in which one combines information into chunks that have a more relevant meaning in LTM in order to recall them better
Term
Articulatory Suppression
Definition
Making a participant verbalize information that is not relevant to their memory task as a way to prevent them from rehearsing the information
Term
Phonological Loop
Definition
Th temporary storage of speech-like information, items are registered as memory traces with a very fast decay but items can b revived through 'subvocal rehearsal' (saying the info to yourself over and over again)
Term
Articulatory Rehearsal
Definition
Saying the information over and over again out loud as a way to store it for a longer period of time and be able to recall it
Term
Central Executive
Definition
Part of the working memory, it is an attentional controller

ex. driving car automatically, road block and they Supervisory Attentional system (SAS) kicks in
Term
Digit Span
Definition
The amount of digits someone is able to remember and store in their STM and recalled in the correct order
Term
Proactive Interference
Definition
Tendency for memory for new information to be interfered with by old info
Term
Retroactive Interference
Definition
Tendency for old info to be interrupted by new info
Term
Release from Proactive Interference
Definition
in participants do a task with the same categories a few times and the performance decreases, when you change categories their performance should 'bump' up
Term
Levels of processing
Definition
Type of processing affects learning and recall

items that are more deeply processed will be better remembered
Term
Nonword repetition task
Definition
Participants repeat fake words that increasingly get longer (more syllables) and their accuracy for repetition goes down
Term
Confabulation
Definition
reflection of something that did not really happen but on may think it did happen
Term
Semantic Coding
Definition
processing an item in terms of its meaning and relating it to the real world as a way to recall the info easier
Term
Distributed Practice
Definition
practicing or studying a little bit throughout a spread out period rather than in one or two long sessions
Term
Massed practice
Definition
Studying information in large chunks of time less frequently than distributed practice
Term
Micro Distribution of Practice
Definition
quizing students right after info is presented as a way to give them better recall - distributing the learning throughout lesson
Term
Internal motivation
Definition
if one is tested on remembering sequences related to their hobbies they will remember better (ie sports fans v. non sports fan with real and nonreal scores)
Term
External Motivation
Definition
A part. does better on recall if they are motivated by something (ie money reward ONLY if they get x amount of answers right)
Term
Learning and Arousal
Definition
Low arou: good imm recall, poor later recall
High arou: Poor imm recall, high later recall

Why?
Low: can focus on info but aren't emotionally connected to it
High: Body cannot focus on info at present time but has an emotional connection to it so will remember better

Moderated aroused is when you learn best
