Glg 101 Week 3 Letter Nonsense

Decent Essays

If I gave you a list of three letter nonsense words, how long do you think you could remember the words? What about half? This experiment is what Herman Ebbinghaus tested in 1885, and the results he collected were plotted into what is now known as the Ebbinghaus “forgetting curve.” Ebbinghaus memorized these syllables for more than a year and then to prove that his results were not an accident, he repeated the entire experiment three years later. He examined how long things remained in our memory and also calculated a formula that measured the savings in relearning information. The bad news about the “forgetting curve” is that the slope of forgetting is quite steep, and most of our forgetting happens within a day of learning the new information! …show more content…

As everyone is familiar with, trying to learn all of the material at one time is called “cramming” and while cramming may get you through the test the next day, research shows that it is actually a very poor way to learn for the long term. The theory of the spacing effect was also developed by Ebbinghaus in 1885, and the spacing effect has held up to numerous testing by researchers over the years. In 1967, Geoffrey Keppel tested the spacing effect on college students using nonsense syllables paired with adjectives (i.e. lum-happy). Half of the subjects studied the list eight times in one day (massed practice) and the other half studied the list two times on each of four successive days (distributed practice). Keppel then tested their memory either one day after the final study session or a week later. The results showed that both groups do fairly well if they are tested the next day, but there is a considerable drop-off in recall if they are tested a week later. Even after the one week delayed testing, the group that exercised distributive practice showed little to no forgetting. Thus, to counter the sharp slope on the forgetting curve, it is extremely important to initially review materials within a day of learning it and to review a couple times after that. Often we feel that we can’t possibly make time for a review session every day in our schedules, but this review is …show more content…

More recent research has shown that testing is not just a passive tool for assessing one’s knowledge, but it is actually one of the best tools for studying and remembering for the long-term. Karpicke and Roediger (2008) gave groups of college students a list of 40 Swahili-English word pairs, asked them to study it for a set time and then tested them on the list over a total of four consecutive study-test trials. Group 1 repeatedly studied and was also repeatedly tested over the whole list. In the other three groups, once a student had correctly recognized a Swahili word and recalled its English translation, it was either: repeatedly studied but dropped from further testing (Group 2), repeatedly tested but dropped from further studying (Group 3) or dropped from further studying and testing (Group 4). The results? Both group 1 and group 3 had the highest recall. Repeated studying had no effect on the student’s ability to recall the information on a final test, given one week later. Only repeated testing embedded the information in the memory, enabling the students to recall it later. Another interesting aspect of this study is that the participants were asked, “How many words do you think you will recall in one week?” Students in all conditions believed they would recall approximately 50% of the words. Students exposed to the most testing grossly underestimated their ability to recall the words while
