AIM:-
i.
To find the memory retention
pattern in age group below 18 years.
ii.
To find the memory retention
pattern in age group 19-35 years.
iii.
To find the memory retention
pattern in age group 36-50 years.
iv.
To find the memory retention
pattern in age group 51 years and above.
INTRODUCTION
In psychology, memory is the process in which
information is encoded, stored, and retrieved. Encoding allows information from
the outside world to reach the five senses in
the forms of chemical and physical stimuli.
From an information processing perspective there are three main stages in the formation
and retrieval of memory:
·
Encoding or
registration: receiving, processing and combining of received information
·
Storage:
creation of a permanent record of the encoded information
·
Retrieval, recall or recollection:
calling back the stored information in response to some cue for use in a
process or activity
Short-term memory
Short-term memory allows recall for a period of several seconds
to a minute without rehearsal. Its capacity is also very limited: George A. Miller (1956), when working
at Bell Laboratories, conducted experiments showing that the store of short-term
memory was 7±2 items (the title of his famous paper, "The magical
number 7±2").
PROCEDURE:
I.
A survey was conducted among the
age groups below 18 years, 19-35 years, 36-50 years and 51 & above
separately.
II.
Names of 12 objects were read out
to them twice and then they were asked to recollect the names of the objects
told to them.
III.
The observations were recorded and
the data was analysed using graphs.

CONCLUSION
Memory
retention capacity was best in the age group below 18 years which declined in
the age group 19-35 years, further declined in the age group 51 years &
above.
Therefore,
Memory Retention α 1/Age
i.e. with age memory retention power decreases.
