2. WHAT IS MEMORY?
Memory is the internal record of the prior
Event or experiences a set of mental
process
that RECIEVES,ENCODES,STORES,ORGANIZES,
ALTERS, RETRIEVES , information over time.

3. THREE STAGES OF MEMORY
• STAGE 1-SENSORY
MEMORY captures what
we see, hear, feel, taste and
smell. Quite simply, it
records the things that you
"sense”. For instance, think
about seeing. We see
innumerable things in the
course of virtually all
waking minutes. However,
unless your attention is
actually captured by
something you see, it is
erased when something
else attracts your interest.

5. SHORT TERM MEMORY
• Short-term memory lasts
somewhat longer; in fact, as
long as you give thought to
something, you can keep it in
short-term memory.
• It will continue to be available
in your memory as long as you
actively think about it.
• If you quit attending to it, it
will be deleted within 10-20
seconds.
• In order to remember
something after that, the brain
has to move it to long-term
memory.

6. • Typically, whenever we refer to
memory, we have long-term memory
in mind.
• Long-term memory can store a
virtually limitless amount of data.
Long-term memory contains
perceptions and concepts that vary
from a few moments old to the very
first weeks of life.
• Long-term memory is like the
immense hard drive of a giant
computer where unlimited detail can
be recorded for a lifetime.
• It is this memory that we construct
our ideas and experiences on, and
ideally bring them back to attention
whenever we need it.

7. OVERVIEW OF A MEMORY CHAIN

8. INTEGRATED MODEL CONCEPTs
ENCODING-process of
translating info into
neural codes(language)
that will be retained in
memory.
STORAGE- the process of
retaining neural coded
info over time.
RETRIEVAL- the process of
recovering info from
memory storage.

9. Varieties of LTM
• TWO TYPES OF LTM
• SEMANTIC MEMORY- Refers to factual
information.
• EPISODIC MEMORY-refers to autobiographical
as where and when the event happened.

10. OVERVIEW OF LTM

11. ORGANISATION OF LTM
• RETRIEVAL CUE- A clue or prompt that helps
stimulate recall and retrieval of stored piece
from long term memory.
• 2 types
• 1)recognition
• 2) recall

12. MEMORY MEASURES
• Recognition is when a
specific cue (face or
name) is matched
against LTM.
• Recall is when a general
cue is used to search
memory.
• Relearning-situation
where person learns
material a second time.

13. FLASHBULB MEMORY
• Where were you when
you first heard:
• 1) the bomb blast of
7/11?
• 2)mumbai terrorist
attack ?

14. FORGETTING
• FORGETTING is the
inability to recall
previously recalled
information.

15. THEORIES OF FORGETTING
• Proactive interference- old information interferes
with recall of a new information.
• Retroactive interference-new information
interferes with recall of old information.
• Decay theory- memory trace fades with time.
• Motivated forgetting-involves the loss of painful
memories(protective memory loss)
• Retrieval failure-the information is still with LTM
but cannot be recalled because the retrieval cue
is absent.
