137: Are Trees Real? (with Yngwie Nielsen and Morten Christiansen)

What goes on in our minds when we construct an utterance? Linguists often use syntax trees to represent the structure of sentences, but are they psychologically real? Yngwie Nielsen and Dr Morten Christiansen have found evidence for something else: we can recognise patterns in strings of words, even when they don't form coherent "treelets". They're giving us a walkthrough of their latest work.
