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 BR Patti, Hannah, Gabe X hand give or pass X objects beginning with ha, ga, pa, or something else entirely |
2x design BR every verb pair has 4 sets of objects... used transitive verbs that could be described in at least 2 ways. 2 verbs prime for the one interpretation, 2 for the other, and the other 4 objects are frequency matched objects to give a base rate. Includes 12 hgp trials, 4 toss trials and 6 other verb pairs |
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 BR showed preliminary priming effects from the object to the verb, about 25% of the hgp trials were 'hand' or 'pass', also showed the 'gi' primed 'gave' better than 'ga' did. |
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 |
