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]
