Irrelevant speech effects with locally time-reversed speech: Native vs non-native language

What is it about?

It is known that speech causes severe destruction on memory task of short time span, even though the speech has no relation with the memory task. We tested that this effect is more related to global temporal features of speech than local ones, or vise versa, with both native and non-native languages.

Why is it important?

The automatically running speech perception mechanism is involved in this paradigm. To ask whether this mechanism relays on more global temporal features of speech than local ones is to reveal temporal aspects of speech perception, and is probably related to a hypothesized dual time-window mechanism in the brain.
