# Raw\_datasheet\_RT_LED_Y.xlsx

describes the data obtained in two different levels of background luminance in three conditions 

### Description of the data and file structure

There are two Excel sheets.

The first sheet contains the personal data obtained for each young subject followed by questionaries.

The another one Excel sheet contains visual reaction time in milisecond in different conditions
