Functional specialization for semantic and phonological processing in the left inferior prefrontal cortex reports a functional neuroimaging study and a review on left inferior prefrontal cortex.

In the syllable counting task subject saw visually presented words that had either 2 or not 2 (1 or 3) syllables.

Group 1 of 8 volunteers with 5 males and 3 females were included in the study.


Subjects were native speakers of English.

[edit] Experiment

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.

[edit] Critique

  1. "event", "baseline", "grammer" and "decade" is regarded as "concrete" word (as opposed to "abstract). Why?
