AB  - Cognitive state decoding is key to brain-computer interface technology, serves as 
      a promising tool for psychiatric diagnosis and rehabilitation, and offers a novel 
      perspective for neuroscientific study. Datasets for decoding cognitive states 
      using optical neuroimaging modalities remain scarce. To address this, we provide 
      an fNIRS dataset acquired during a Stroop task, consisting of frontal hemoglobin 
      responses from 55 young adults. Each participant completed three sessions of 
      color-word Stroop task within approximately 2 weeks, to collect more than 30 
      trials per condition while avoiding mental fatigue caused by a single session. 
      This dataset supports a range of applications, from studying conflict inhibition 
      to building decoders for neurofeedback training and large-scale cross-subject 
      fNIRS models, while also facilitating the development of signal processing 
      algorithms for hemodynamic signals.
