Digit Span Test • This test was created by J. Jacobs in 1887 to test the memory span of his students. • From then on it has been an important tool in the study of short term memory. • It has been recreated many times and many different variations have been done on it.

Short Term Memory • Function of the brain allowing one to forget unimportant information and pass on important information to be stored. • Due to the constant influx of new information short term memory is one of the most important processes of the brain

Visual Memory • Allows interpretation of the visual field. • Received through the occipital lobe. • Attaches to the prefrontal cortex for transmission of memory.

Auditory Memory • Brain interpretation of the audio field. • Collected in the auditory cortex. • Attaches to the prefrontal cortex for memory transmission.

Learning • Various approaches to remembering. • Chunking; breaking up information into smaller, easier to remember segments

Purpose The purpose of this experiment is to test if people remember better by hearing things or by seeing things.
![Hypotheses Subjects will remember more information by auditory recall than by visual recall. Null: Hypotheses Subjects will remember more information by auditory recall than by visual recall. Null:](http://slidetodoc.com/presentation_image/11dcfc860c4c59da8cbdd646b068dd8e/image-9.jpg)
Hypotheses Subjects will remember more information by auditory recall than by visual recall. Null: There will be no significant variation in recall between auditory and visual stimuli.

Materials • Table to record results. • Seven sets of random numbers that range from four digits long to ten digits long. Each set increase in length by one digit. • A different seven sets of random numbers that range from four digits long to ten digits long. Each set increase in length by one digit. • Twenty freshman subjects CCHS. • Quiet Room • Stopwatch
![Procedure for Auditory • The test the proctor read the first string of numbers Procedure for Auditory • The test the proctor read the first string of numbers](http://slidetodoc.com/presentation_image/11dcfc860c4c59da8cbdd646b068dd8e/image-11.jpg)
Procedure for Auditory • The test the proctor read the first string of numbers aloud to the subject. • The proctor waited thirty seconds. • Subject was asked to orally repeat the string of numbers. • The process was repeated with a new set of random numbers which increased by one digit each time until the subject revealed a mistake in sequence or number
![Procedure for Visual • The test proctor gave the subject a piece of paper Procedure for Visual • The test proctor gave the subject a piece of paper](http://slidetodoc.com/presentation_image/11dcfc860c4c59da8cbdd646b068dd8e/image-12.jpg)
Procedure for Visual • The test proctor gave the subject a piece of paper with the string of numbers on it. • The subject got fifteen seconds to look at the number. • The subject then handed the paper back to the proctor. • They waited thirty seconds. • The subject then repeated the number they saw back to the proctor orally. • This process was repeated with a new set of random numbers until revealed a mistake in sequence or number

ANOVA Analysis of Mean Scores • ANOVA analysis compares variation between two groups • Reject null if p value is below 0. 05 • Calculated p value=0. 120511 • 0. 120511>0. 05 the difference is INSIGNIFICANT
![Conclusions • The null hypothesis was accepted because the p value was above 0. Conclusions • The null hypothesis was accepted because the p value was above 0.](http://slidetodoc.com/presentation_image/11dcfc860c4c59da8cbdd646b068dd8e/image-17.jpg)
Conclusions • The null hypothesis was accepted because the p value was above 0. 05. However the visual had a better overall average than the auditory.

Extensions Limitations • More test subjects • To few subjects • Using a tape for the audio test for less variation • More than two sets of tests Have four random sets of numbers for both auditory and visual tests • Too much variation in the auditory test. •
