Description
Functional near-infrared spectroscopy (fNIRS) visually-evoked data collected from healthy adults and children. We recruited a total of 40 adult participants (20 women, age: 31.05 ± 3.94 (SD) years) and 19 children (5 girls, age: 7.20 ± 3.01 (SD) years). Adult participants filled in the Autistic-traits Quotient (AQ) questionnaire, a 50-items self-administered report validated for the Italian version. The items consist of descriptive statements assessing personal preferences and typical behavior. Since child self-report might be affected by reading and comprehension difficulties, the children's version of Autism Spectrum Quotient (Italian version of AQ-child) was completed by parents. To measure changes in total Hb (THb) concentration and relative oxygenation levels (OHb and DHb) in the occipital cortex during the task, we used a continuous-wave NIRS system with 8 red light-sources operating at 760 nm and 850 nm, and 7 detectors, forming an array of 22 multi-distant channels.
The dataset includes 2 '.zip' files containing artifact-free visually-evoked transients HDF data, exported from Homer 3 (https://github.com/BUNPC/Homer3) in '.txt' format. Subfolders correspond to different stimulation conditions, for details refer to this paper [preprint coming soon].
Each txt file is named with the corresponding subject code and contains two events [tagged as 1 (baseline) and 2 (stimulus)].
The file 'annotations.csv' contains the following fields:
Code [Subjects id name, that corresponds to the filename in the recording folders]
Sex [M or F]
Valid [1 or 0, 0 means excluded subject]
Age [int]
CH_exclude [list of excluded channels]
CH_Red [ list of channels that did not passed the calibration step]
Category [adult or child]
Cartoon_fixed [cartoon name]
Cartoon_chosen [cartoon name]
AQ [global AQ score]
AQ_S [ AQ subscale social ]
AQ_C [ AQ subscale communication ]
AQ_A [ AQ subscale attention]
AQ_D [ AQ subscale detail]
AQ_I [ AQ subscale imagination]
