research that was made by Murdock (1962) about the serial position effect. The expectation were that the letters at the beginning of the list will be remembered better that the letters in the middle of the list and that is because the participants will start to rehearse the letters they see at first and rehearsing the letters can move them from the short term memory to the long term memory to be recalled again when needed (primacy effect). And the other expectation was that the letters at the end of

When people first started using radars during World War II it was to provide information about aerial attacks heading towards them. Another way people were using radar was to try to prevent collisions like the Titanic hitting the ice burg and sinking. It wasn’t until after
