Nature of Exptl Trials |
4 gi-primes, 2 ga-primes, 6 ha-primes plus their frequency matched words to use as a comparison. I was pretty new at this at the time. |
3x3 design |
2x design |
Nature of Fillers |
toss, throw, show, and offer trials with a balanced number of verbs and characters |
18 super-strong phonological priming trials for transitive verbs, 56 transitive verbs hum-hum among 12 different verbs! most trials include Simon as the agent |
4 transitive verbs... Simon kicks, pulls, pushes, or touches a woman or a boy |
Results |
10 subjects |
12 subjects, preliminary feedforward phonological priming, also effects of repetition on fluency and ditransitive noun phrase ordering |
not yet analyzed |
Problems |
imbalanced number of trials per experimental condition! fillers often repeated the same people and objects, work on finding feedforward evidence first, too many experimental trials? |
no variation of verbs |
not yet analyzed |
Breaking News
I ran a subject in experiment 2 today, but this time made it a communicative task (with me) and reinstated the context of the recall experiment. Between the two changes, subject 14p changed verb usage pretty regularly (I won't have a real idea until I look at the data), but he did not get stuck saying 'gave' the whole time.
I would like to try a version where I am not the other subject... perhaps I could have a confederate to press the space button and turn the task back into a communicative one. The memory task portion seemed to trip subject 14p up. When asked he said, "I wanted to make sure that I was labeling the objects correctly. I thought that one of the items was a handle at first, but I couldn't remember if it might have had a different label." Either way, I'm excited and I hope that this keeps happening. I'm running two more people in the old experiment tomorrow. -Katrina Housel 7/31/08
