- Phonological processing associated with left inferior frontal gyrus near the inferior frontal sulcus (BA 44/45)
- Semantic processing associated with the ventral aspect of the left inferior frontal gyrus (BA 47/45)
In the syllable counting task subject saw visually presented words that had either 2 or not 2 (1 or 3) syllables.
|Subject group #1 (help)|
|Subjects/♂/♀:||8 / 5 / 3|
Group 1 of 8 volunteers with 5 males and 3 females were included in the study.
Subjects were native speakers of English.
The words presented was constructed from a previous list. The subjects present a response button, based on the target. Half of the subjects wiehn the word was abstract, upprcase or two-syllable, the other half when it was concrete, lowercase or did not have two syllables. The items was presented for 1.5 seconds with a 1.13 second interstimulus interval. The words are related to words from Functional magnetic resonance imaging of semantic memory processes in the frontal lobes.
- "event", "baseline", "grammer" and "decade" is regarded as "concrete" word (as opposed to "abstract). Why?
