Moray
Selective attention is when people are presented with two or more simultaneous ‘messages’, and process or attend to only
one of them by tuning out the others. This is measured using dichotic listening tasks. Broadbent investigated the aviation
industry, raising awareness of the importance of air traffic controllers to be able to selectively attend to important
messages whilst rejecting others. Cherry was interested in conducting experiments on this topic. He created dichotic
listening tasks, asking participants to listen to two different messages, one in each ear, and shadow one of them, thus
setting up a block to the rejected message. Cherry found that very little could be remembered from the unattended
message. Moray was keen to replicate Cherry’s work and extend knowledge of selective attention and dichotic listening.
Simons and Chablis (Structure)
Simons and Chabris
Moray had previously research into attention, investigating into auditory attention. Simons are Chabris were interested in building on this knowledge and investigating into visual attention, particularly inattentional blindness. This is when attention is diverted, observers often fail to perceive an unexpected object. Previous research had already been conducted in this field. Mack and Rock investigated into computer based displays,
where participants were given a task to do and then presented with an unexpected object, such as a smiley
face. They found that observers failed to see it. However, this method was criticised for being
unrepresentative of how visual attention works in real life. Neisser investigated further, using video based
displays. Participants were asked to watch basketball players passing the ball and count the amount of passes,
during which a woman with an umbrella walks across the screen. Neisser found that the majority of
participants failed to see the woman. However the research was criticised for being a poor quality video. Both
of these studies provide evidence for inattentional blindness. Yet Simons and Chabris were eager to enhance
the work of both researchers making the task more representative of inattentional blindness in real life.
