Memorize this…

You will be given 30 seconds to memorize each list of words…

After the 30 seconds you will be asked to write down as many words as you remember

alligator - apple - arrow - baby - bird - book - butterfly - car - corn -

flower - hammer - house - money - microscope - ocean - pencil - rock

- shoes - table - window

anger - belief - boredom - chance - concept - effort - fate - freedom - glory - happiness - honor - hope -

idea - interest - knowledge - mercy - mood - moral - theory -

truth

ator - botam - crov - difim - firap - glimoc - ricul- hilnim - jolib -

kepwin - leptav - lumal - mib - natpem - peyrim - rispaw - stiwin -

tubiv - vopec - yapib

Why was the first list easier? The ability to remember a word

depends on how meaningful the word is to a person.

Additionally, the "concreteness" of a word is important for memory. Concreteness refers the ability of a word

to form a mental image. A word with high concreteness is easy to

"see"; a word with low concreteness (an "abstract" word) is difficult to visualize.

THREE is the KEY for MEMORY

MEMORY

The power or process of reproducing or recalling what

has been learned and retained

Memory

Sensory

Short Term

Long Term

Transferring information so the nervous system can process it

Visual CodeAcoustic CodeSemantic Code

Process by which information is remembered over a period of time.

A few seconds ?Depends on effort during encoding…

Process of obtaining information that has been stored in memory

How well it is retrieved depends on how effectively it was encoded and

stored!

3 Types of Memory

1. Sensory Memory2. Short Term Memory3. Long Term Memory

Sensory Memory

Very brief (1-2 seconds) memory storage immediately following initial stimulation of a receptor.

Two Types: Iconic Memory – visual sensory information Echoic Memory – auditory sensory information

Sensory Memory

Prevents us from being overwhelmed…Anything you do not pay attention to vanishes in seconds

Gives us some decision timeAllows you to decide whether it is worth paying attention to.

If you choose to pay attention, the info is automatically transferred to short-term memory.

Short Term Memory

The capacity for holding a small amount of information in mind in an active, readily available state for a short period of time

Capacity? Limited to about seven

unrelated items. (+/- 2)

MEMORY ACTIVITYYou are about to do a

short term memory test. A few letters will flash on the screen for 4 seconds. Your job is

Strategy?

What (if anything) did you do to help

yourself remember the

letters?

STM… Maintenance Rehearsal: a system for remembering that involves repeating information to oneself without attempting to find meaning in it.

Chunking: the process of grouping items to make them easier to remember

Experiment:

1. Number your papers from one to twenty.

2. You will see a list of terms - try to remember them in order.

Primacy/Recency Effect

The middle items on a list typically are harder to remember because your attention is split between trying to remember previous items and trying to rehearse new ones.

• WORKING MEMORY: Working with current information STM is also referred to as this LTM can also fit here – info stored being

recalled for current purposes

Long Term Memory The storage of and UNLIMITED AMOUNT of

information over extended periods of time…(forever?) LTM involves all the previous processes

Types of LTM

Procedural: Permanent storage of learned skills that does not require conscious recollection

Declarative: stored knowledge that can be called forth consciously as needed

Episodic: Chronological retention of the events of one’s life Everyone’s is unique

Semantic: Knowledge of language, including its rules, words and meaning Shared with other speakers of language

1. First kiss 10. Using a computer

2. Riding a bike 11. Spell C-A-T

3. First day in high school 12. Playing the piano

4. List the 50 states 13. Describe a fight to someone
