Iconic and Echoic Memory
BY RILEY O’SHAUGHNESSY
Iconic mem-ory is a typeof short term,
visual memory.
Characters, numbers, and other stimuli can be remembered after brief
exposure, but is forgotten by the person VERY quickly
TEN
SECONDS
LATER
Suggests the idea that a sensory perception, when not enforced, decays faster than a rotting tree
Echoic memory is the auditory
counterpart to iconic memory
When an auditory stimuli occurs, a brief mental echo occurs too.
Echoic memory lasts a little longer than iconic memory, but still is forgotten within ten seconds
Speedy, isn’t it?
Three-Stage Processing
Method developed by Atkinson and Shiffrin
Contains three steps to learning memory
’’How many symbols do you recognize from above? At one point, most if not all of these symbols were registered through your sensory memory!
All of Dory’s thoughts end up in her short-term memory and is forgotten in her case, but not in ours. The few thoughts we want to remember then go to our long-term memory.
Long-term memory
Elephants are supposed to have great long-term memories!
The next-in-line effect is when one does not pay attention to the thing or person in front of them because they are focused on themselves. It is like buying the i-Wood.
ENCODING
• Encoding is when you organize a memory’s meaning and image so that it can be stored.
• This is a memory being encoded.
Storage
• Storage us keeping things in sensory, working/short-term, or long-term memory for later recall.
• A forgetful person’s brain.
• A rememberful person’s brain.
• Incorporating misleading information into one’s memory of an event
Because of the misinformation effect…
Cookies Are
GOOD!!!
Attributing to the wrong source an event we have experienced, heard about, read about, or imagined
Cookies are GOOD!!!
Source amnesia isn’t like regular amnesia where you forget everything. It’s only when you forget where you heard something.
Memory

experience emotions
Abnormal things

memory
I remember because I
can retrieve facts,
experience, etc…
Flashbulb memory
I feel so
emotional!
I remember so vividly! It was the third of June on a hot sunny day …
What does it mean…?!
Mnemonics and Chunking…
Mnemonics – memory aids, especially those techniques that use vivid imagery and organizational devices.
Like the colors of the rainbow!
PEMDAS – Please Excuse My Dear Aunt Sally
Is a common mnemonic to remember the order of operations (this flow of power from power plant to home shows PEMDAS.
Mnemonic devices act in many ways like this file cabinet. They act as organizational memory devices.
Chunking != Chunky.
Chunking == organizing items
into familiar, manageable units;
often occurs automatically.
We chunk things such as phone numbers into groups of 3 or 4 to help encode them to memory better.
Chunking helps us to identify words and symbols of our language.
Teenagers are independent and don’t care what their parents think
Implicit memory is independent of conscious recollection
He might not remember last night when he wakes up, but the effects are still there
Like implicit memory !!!!
We all have these moments
But implicit memory is the concept behind
“practice makes perfect”
Explicit memory: memory of facts that once can consciously know and declare
Explicit Memory Master
This moment will be in their explicit memory for the rest of their lives
Explicit memory also applies to experiences
