Modelling the Emergence and Dynamics of Perceptual Organisation in Auditory Streaming
Figure 2
A) A linear chain describing event A, followed by 100 ms of silence, event B, which is then followed by 50 ms of silence; and a looping chain which alternates between events A and B every 100 ms. The red “phase” triangle indicates that the looping chain is currently passing through event B. B) The building of chains in response to the input sequence ABAC. Each input event adds a new singleton chain and causes existing chains to split into two new versions (marked by wide arrows), one adding the event and the other omitting it. When A is input for a second time, two potential loops are noticed: AB← and A−←. When event C arrives, the first of these fails to predict B correctly and is therefore removed.
