The document discusses the stages of memory formation and retrieval. It explains that memory involves encoding external information through the senses, storing it permanently, and later recalling it in response to cues. It describes the three main types of memory as sensory memory, short-term memory, and long-term memory. Sensory memory holds information for seconds, short-term for seconds to a minute, and long-term relies on neural connections for permanent storage. The document also mentions working memory involves a central executive, phonological loop, and visual-spatial sketchpad according to a 1974 theory.

2. What is the memory?
•In psychology, memory is the process in
, andstored,encodedwhich information is
. Encoding allows information thatretrieved
is from the outside world to reach our
senses in the forms of chemical and
physical stimuli..

3. The main stages in the formation and
retrieval of memory
•or registration:Encoding
receiving, processing and combining of
received information
•creation of a permanent record of:torageS
the encoded information
•: callingrecollectionorrecall,Retrieval
back the stored information in response to
some cue for use in a process or activity

4. 1-Sensory memory
•HoldsSensory memory
sensory information for a few
seconds or less after an item is
perceived.

5. 2-Short-term memory
•Short-term memory allows recall for a period
of several seconds to a minute without
rehearsal.
•Short-term memory is believed to rely mostly
on an acoustic code for storing
information, and to a lesser extent a visual
code.

6. 3-Long-term memory
•The storage in sensory memory and short-term
memory generally have a strictly limited capacity
and duration, which means that information is not
retained indefinitely.
•Long-term memories, on the other hand, are
maintained by more stable and permanent changes
in neural connections widely spread throughout the
brain.

9. Working memory
•In 1974 was that eley and Hitch proposed there
theory about short term memory consists of
three basic stores:
•central executive.
•phonological loop.
•visual-spatial sketchpad.
