Total Recall
Hannah PohlmannGrade 9Academy of Notre Dame de Namur
Problem
Does one’s environment and age affect how well they study/memorize?
Research
Today:
January 25th 2011
Research
Memory in General Short-term (used in this experiment)▪ Part of brain is the hippocampus, which is
located inside the temporal lobes▪ Things remembered (such as words) and then
quickly forgotten ▪ Easily disrupted▪ Information is converted into long-term from
short term▪ Amnesia if there isn’t enough time to convert
Research Effects of Distraction on Memory–Tyler Jewett
Hypothesized that “the ability to recall words decreased as distraction increased”
Tested subjects by giving them a list of 20 simple 4-5 letter words Given 1 minute to memorize Sat in silence for 2 minutes Then wrote down all remembered words in 2 minutes Second time, the researcher read from the U.S. constitution during
the memorization time ▪ During the 2 minutes between and the two minutes of recall, the researcher
continued to read from the constitution Ability to ignore increases with age
▪ Two test for adults and children▪ Adults did about the same but children did worse with a distraction
ADHD processes the same but cannot remember as well Students scored higher on single-task vs. duel-task tests
Research
CBS and Oxford Do social factors and age affect
memory?▪ Memory/ Cognitive function is affected by
lifestyle, family and other relationships, and a person’s feeling of control over their life▪ The young, healthy, educated, and people
who feel they have control over their life did the best▪ Most memory is based in confidence
Research
WSJ and Wiley Online Library Study involving 5 different music
conditions Memorized letter sequences Music and random digits hampered
results▪ Preference made no difference
Did better with repeated digit and silence
Research
Philly. Com Hearing half of a conversation distracts
much more than a whole conversation Followed dots and clicked on letters
under both conditions With letters there was 10% drop in
corrects Not words but the random occurrences
that distract
Research
Science Direct School near elevated train Loud side of the building scored lower on
reading skills Insulated ceilings and walls were
installed and both sides scored the same
Research
Access Excellence-Brenda Brown Similar to my project Light v. dark, cold, music The researcher starts listing three words
and adds a word each time until the subject cannot remember anymore
Hypothesis
If one’s environment and age changes, then how well they study or memorize will change too.
Materials
Stopwatch Informed consent permission slips Volunteers Lists of words Music TV Chairs Quiet rooms Blank paper
Procedure Wrote up 4 different lists of 30 words Found 15 (or more) volunteers Had volunteers memorize words for 2 minutes under
different conditions Using a different list every time
After each 2 minute interval, saw how many words the volunteers remember Giving them 2-3 minutes to recall what they memorized
and write it down on provided paper Correct list
Checking for error and or any patterns in memorization Compared results to see how the volunteers were
affected

Conclusion Teens are the best Teens and children were not effected by
environment TV effected adults Quiet and Music-teens are better than children
but children and adults are the same TV-Teens are best In a quiet, comfortable environment all ages
were the same Supports hypothesis Results may have differed with a larger study
Subjects also got tired as the tests continued
