This makes awareness of the serial position effect vital for effective teaching. Teachers often have to try and squeeze large amounts of information in just a few classes and hope that their students are absorbing the information. This begins all the way in childhood, when teachers plan their classes. It is usually up to people in leadership positions to decide how to present important information. Without knowledge of how we best remember information, we may use tactics such as repeating a list in the same order again and again, believing that repetition is enough for information to be committed to memory.Īlthough individually, we can use tactics that try to counter the ways in which the serial position effect causes us to forget items in the middle of a series, we are often not able to control how information is presented to us. We need to be aware of how our memory works in order to organize information in a manner that is most optimal for recall. The serial position effect means that your memory is hindered for information that is presented in the middle of a series.

As you go to write down the last sentence he spoke, you realize you only remember the first few words and the last few words, but not the whole sentence. You want to write down the definitions, but he is speaking quite quickly. However, what happens when we need to remember information that we only briefly encounter? For example, imagine you are in a lecture, and your professor is explaining some important definitions. Therefore it was concluded that the results clearly supported the idea of short-term memory having limited capacity.Not being able to remember all of the items on our grocery list may not be the end of the world, because we can easily write down what food we need to buy so that we can reference it again, instead of relying on our memory. Afterwards the result clearly shows that the participants’ long-term memory was not affected as they were able to recall the first words from the list, while on the other hand differences occurred when recalling the words at the end of the list. The men were again asked to count for 30 seconds, and then allowed for the third time to recall as many words as possible. Then the men (participants) were asked to count for 10 seconds and afterwards were asked for the second time to recall as many words as possible. After all 15 words were shown to the men the experimenters asked them to recall as many words as possible. A total number of 46 participants (men) were shown words projected on a screen every 3 seconds. Another study of displacement by Glanzer and Cunitz (1966) which aimed to test out whether short-term memory has a limited capacity could be used to highlight this study.
