Neuroimaging studies reliably reveal ventrolateral prefrontal cortex (VLPFC) activation for processing of abstract relative to concrete words, but the cause of this effect is unclear. Here, in a convergent neuropsychological and repetitive transcranial magnetic stimulation (rTMS) investigation, we tested the hypothesis that abstract words require VLPFC because they depend heavily on the semanti...

At least a subset of our vocabulary must be grounded in the sensorimotor world for the words to have meaning in our minds. Analysing definitions recursively in dictionaries which use a fixed vocabulary to define all their words can give some idea of how new meanings can be grounded in terms of already grounded ones. Concrete words should be easier to ground than abstract ones, because sensorimo...

We demonstrate that a supervised annotation learning approach using structured features derived from tokens and prior annotations performs better than a bag of words approach. We present a general graph representation for automatically deriving these features from labeled data. Automatic feature selection based on class association scores requires a large amount of labeled data and direct votin...

The concreteness effect occurs in both normal and language-disordered populations. Research suggests that abstract and concrete concepts elicit differing neural activation patterns in healthy young adults, but this is undocumented in persons with aphasia (PWA). Three PWA and three age-matched controls were scanned using fMRI while processing abstract and concrete words. Consistent with current ...
