Split-span paradigm

from Wikipedia, the free encyclopedia
The digits presented at the same time are reproduced by ear, not in chronological order.

The split-span paradigm is based on an experiment by Donald Broadbent in 1954. In this, the test subjects are presented with a sequence of pairs of digits on the right and left ears at the same time, e.g. B. 3-9, 4-7, 5-1 (left vs. right ear). The test subjects were given the task of reproducing this sequence of numbers as completely as possible. It was found that the reproduction was preferably based on ear (3-4-5, 9-7-1) and not according to digit pairs (3-9, 4-7, 5-1).

Broadbent concluded from this result that the choice between different messages is based on the physical stimulus characteristics (e.g. which ear). This paradigm, along with dichotic hearing and the psychological refractory period (PRP) studies, forms the basis of the filter theory of attention .
