These pages contains example stimuli from the paper "Recovering Sound Sources From Embedded Repetition" by McDermott, Wrobleski, and Oxenham (2011, PNAS). Headphones are recommended. Quicktime must be installed for the sounds to play.
**Please note - sound files make take a few seconds to load. If not all sounds load, please try refreshing the page.

Experiment 6 stimulus examples
There are two examples of each condition. In all examples, the probe stimulus is the target (i.e., these would all be trials where the probe sound was one of the sounds in the mixture). In the variable conditions, the probe usually sounds like what you heard in the mixtures, whereas in the repeating conditions, it generally doesn't.

**Note that there are only six presentations of the target, instead of the ten used in the experiments. The effect is readily heard with fewer presentations, and this makes the sound files load faster.**
