Hannah Pohlmann Grade 9 Total Recall
Problem • Does one’s environment and age affect how well he or she studies/memorizes? • Something I use every day • Parents and rules
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” • Ability to ignore increases with age • Adults did about the same, but children did worse with a distraction • Do social factors and age affect memory?-Oxford • Hypothesized that: Memory/ Cognitive function is affected by lifestyle, family and other relationships, and a person’s feeling of control over his or her life • The young, healthy, educated, and people who feel they have control over their lives did the best • Most memory is based in confidence
Research • WSJ and Wiley Online Library • Music and random digits hampered results • Preference made no difference • Did better with repeated digit and silence • Philly. Com • Hearing half of a conversation distracts much more than hearing a whole conversation • Random occurrences cause distraction, not just words by themselves
Research • Science Direct • Noise from elevated train affects reading skills of children • Access Excellence-Brenda Brown • Similar to my project • Designed experiment using different conditions to test effects on memory
Hypothesis • If one’s environment and age change, then how well he or she studies or memorizes will change too.
Materials • Stopwatch • Informed consent permission slips • Volunteers • Lists of words • Music • TV • Chairs • Quiet rooms • Blank paper • Pencils
Procedure • Wrote up 4 different lists of 30 words • Found 15 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 remembered • Giving them 2-3 minutes to recall what they memorized and write it down on provided paper • Correct lists • Checking for errors and or any patterns in memorization • Compared results to see how the volunteers were affected
Variables • Independent: Environment used • Dependent: The person’s memory • Control: quiet and regular chair • Constant: duration of time used to recall and memorize the information and word lists
Conclusion • Teens are the best • Teens and children were not affected by environment • TV affected adults • All environments-teens are better than children • The adults are the same as the children except in the music environment • TV-Teens are best • Partially supports hypothesis • Results may have differed with a larger study • Subjects also got tired as the tests continued
