You know, that thing where you do science for cake?
At the weekend Helen and I were experimented on, and then to make up for it were given cake!
Doing psychology or linguistics experiments is a fairly common feature of the undergraduate lifestyle. There are always MSc or PhD students willing to give you something in exchange for screwing up their experiment giving them useful data.
Emily’s doing some research into the two-stage model of word recall/production. Maybe she’ll actually blog about it at some point, and give the proper details. Until then you’ll have to put up with my loose interpretation of her explanation from Saturday.
- Word recall and production is modelled as a two stage process.
- The first stage calls up semantic details and (crucially) syntactic details. So you know what the word means and how to use it. But you don’t actually know the word!
- The trick is to force people to manage the first step but to stall at the second step — the point where the word is on the tip of your tongue but you just can’t quite bring it forth. Tip-of-tongue state (ToT from now on).
- Once you’ve got your lab rats into ToT you can ask them questions which should, according to the model, be answerable — like whether the word is a mass or count noun.
(Emily’s actual work relates to sign language production too, so all this was being done on native English speakers as a control group. Then the hard work of putting signers into tip-of-finger state must commence.)
The actual experiment involved watching a screen flash up definitions for words, which we then had to write down. The hope was that we’d eventually hit a definition for which we knew the word but couldn’t quite bring it to the fore. In which case there were further boxes to complete regarding initial letters, syllables, mass/count. Out of 60 definitions I only found myself in ToT once. Compared to about 5 occasions when I couldn’t think of a word at all that would fit the definition.
So we did that, ate chocolate cake and drank tea.
We walked around the shops in the Newington and Grassmarket area for the afternoon. Got some lunch in Cafe Luciano (amazing bacon rolls) and took a bus over to Stockbridge for more wandering. We met Sarah (from our old sign language class) and her partner (Steve?) in the one pub that wasn’t completely rugbified to the gills. Then we went over for tea at Sarah and Ferdia’s (different Sarah). I now know what Julia Roberts’ favourite drink is.
