Comparing The Amount Of Short-Term Retention Of Individuals

The results I got for this experiment was that the amount of trigrams remembered in the control was higher than the experimental. The reason for this was that the experimental group waited 15 seconds before writing the trigrams, and the control group didn’t which affected a lower result for the experimental group showed in the graph. There is also a decrease between the experimental and control median by two points. The study used to attempt to replicate was the experiment conducted by Lloyd R.Peterson and Margaret Jean Peterson in September, 1959. The experiment was conducted to investigate if there is short-term retention of individual by using verbal items after each short intervals. Similarity between my experiment to peterson and …show more content…
Similarly to the peterson and peterson trial which is that it lacks ecological validity because people don’t memorize trigrams in a daily basis and also the experiment was conducted in a classroom which makes the experiment less natural. An improvement that could have be made in my study is the number of participants that were in the study, there was an uneven amount of participants in the experimental and control group. In the experimental group there was 12 participants and 11 participants in the control group. A modification to this is making the teacher be another participants in the control group so they both can be even. Other improvement that can be made is that some participants had already conducted similar experiment to ours in previous classrooms which leads to demand characteristics in some of the results. Leading to the participants having changes in their behavior which can change the outcome of an experiment. A possible modification to this may be to ask the participant ahead of time who conducted previous experiment and tell them to nicely step out the room and not talk about it to other participants on what they have
