Individual Brain Charting: RSVP Language

This dataset contains functional magnetic resonance images (fMRIs) of 12 subjects performing RSVP Language task to localize the areas implicated in language comprehension, participants were presented with stimuli consisting of sequences of words, pseudowords or nonwords. For some conditions, these sequences were composed by well-formed sentences. They were presented as visual stimuli, using a Rapid-Serial- Visual-Presentation (RSVP) paradigm. Concretely, there were six experimental conditions featuring the different types of stimuli: i) complex meaningful sentences, containing at least two clauses (e.g. a main and a relative clause); ii) simple meaningful sentences, with only one main clause; iii) jabberwocky, obtained from well-formed sentences whose content words were replaced by meaningless, yet pronounceable pseudowords; iv) lists of words; v) lists of pseudowords; and vi) list of non-words (aka consonantstrings). Following each sequence after a short delay, a probe (which could be a word, pseudoword or non-word) was displayed with a 50% probability of having been presented in the sequence. Participants had then to indicate, by pressing one of the two possible response buttons, whether the probe had appeared in the sentence. One session of data collection comprised six runs; each of them included sixty trials related to the six experimental conditions, i.e. ten trials corresponded to one condition. The order of the trials was pseudo-randomized within and between runs across participants, such that the same experimental condition did not occur in two immediately successive trials. A trial lasted ten seconds. It started with the display of a fixation cross for two seconds, followed by the display of a blank screen for 0.5 seconds. Afterwards, a sequence of ten stimuli was presented at a rate of one stimulus per 0.4 seconds. Further, a blank screen was displayed during a randomly varying period of time between one and 1.5 seconds, followed by the display of a fixation cross for 0.5 seconds plus a probe stimulus for 0.5 seconds. Finally, the stimuli were cleared and a response-time window opened for 2 seconds.
