dc.description.abstractThe field of cognitive neuroscience has benefited considerably from single- and multiple subject analyses, as well as qualitative methods. The current study has performed a multiple subject analysis alongside a group analysis and discussed the data in a quantitative and qualitative manner. Ten stroke patients and four healthy controls performed a context-driven picture naming task while their brain activity was recorded using electroencephalography. They listened to audio recordings of sentences that were played in normal temporal order, in one condition, and in a reversed temporal order in another. The comparison of the two resulted is a measure of language comprehension. Using a cluster-based permutation analysis after a frequency analysis, no significant results were found. Nonetheless, some descriptive tendencies were found: A higher electrophysiological power around 10Hz in the normal condition compared to the reversed condition, accounted to production-based prediction, and a higher electrophysiological power in the alpha (8-12Hz), interpreted as the focus on an auditory stimulus, and beta (15-25Hz) frequency range, interpreted as auditory stimulus novelty. The findings indicate an added value of qualitative- and multiple subject analyses when performed collectively with quantitative- and group analyses.
