Dichotic listening theory12/13/2023 ![]() Selective attention can be tested using the dichotic listening task, first used by Donald Broadbent in the 1950’s.Selective attention is the ability to focus on individual stimuli whilst ignoring irrelevant stimuli in the subject’s perception.Section Bank P/S Section Passage 1 Question 6 Section Bank P/S Section Passage 1 Question 5 Section Bank P/S Section Passage 1 Question 4 This test is still used to test selective attention. In this task, he sent two alternating messages to the test subject’s left and right ears and tested subject’s ability to attend to one side at a time. In order to test how we focus this spotlight, one scientist named Donald Broadbent designed the dichotic listening task (1958). Selective attention is like a spotlight we can use it to focus on details that are important whilst ignoring irrelevant information in our perceptions. It is the process of focusing on a particular object in an environment for a set time whilst tuning out unimportant details or tasks. Selective attention is demonstrated when many stimuli are present, and a person ignores the non-task-related stimuli. Selective attention can be thought of as the allocation of limited processing resources: your brain can only devote attention to a limited number of stimuli. It is a cognitive process that makes it possible to focus on relevant stimuli and respond to it. My other grumble is that the title is misleading, as the book is wholly concerned with dichotic techniques and cerebral organization.Selective attention is the ability to choose and concentrate on relevant stimuli. It is a pity that a book of this importance was not typeset, but I expect John Wiley and Sons were driven by the realities of economics. In fact, the bookâs last chapter focuses on this issue, and the author, Harshman, gives a foretaste of the complexities which await us. The implication which one may draw from these chapters in particular, and from the whole book in general, is that the problem of individual differences between subjects and groups of subjects must be addressed before consistency and order may be seen in the data. For the reader unfamiliar with recent developments in this literature, these two chapters read like stages in the unravelling of a mystery of which Conan Doyle would have been proud. The findings that subgroups of schizophrenics can be distinguished by their performance on dichotic tasks, as can subgroups of patients with depressive disorders, has far-reaching implications for models of underlying processes.
