![]() ![]() Before each experiment the participants were given four passages of prose to shadow for practice. The messages were of equal loudness, judged by each participant. Method: A tape recorder was used in this lab experiment, which was modified with two amplifiers to allow two outputs, one to each ear through a set of headphones. ![]() The first experiment in this study aimed to test Cherry’s findings more rigorously, while experiments 2 and 3 aimed to investigate other factors that can affect attention in dichotic listening Divided attention is tested using a dual-task technique, whereby participants must attend to two or more messages, which rather than focusing attention, deliberately divides it. Cherry found that those who ‘shadowed’ a message in one ear, were unaware of the content of the message in the other ear. This is known as dichotic listening and was first investigated by Cherry (1953) when researching the cocktail party phenomenon. Messages are repeated aloud as they are heard. The most popular way of doing this is to use shadowing, in which one message is fed into one ear and a different message into the other. Selective attention is tested by presenting two or more ‘messages’ at the same time and participants are instructed to process and respond to only one of them.
