EEG data and psychometric results from children with learning difficulties

Description

1. Objective To perform a psychophysiological evaluation of reading and mathematical skills in children with low academic performance. 2. Sample One hundred and two children participated in this study. Each child was allocated into one of the following groups: a) 51 Children with low academic performance in reading. b) 51 Children with low academic performance in math. 2.1. Sample selection criteria * Children aged between 7-13 years. * Not to be diagnosed with any neurological disorder. * Capacity to read a simple text and solve arithmetic facts * Indistinct gender and socioeconomic level. 3. Methods Data collection was carried out across two stages: I) Psychometric evaluation, where reading, spelling, math, attention levels, and IQ were assessed. These results determined which academic skill was the most affected. II) EEG acquisition, by designing two experimental paradigms. For children in the reading group, three passages were displayed and should have been read out loud. After that, three multiple-choice reading comprehension questions were presented. Regarding the math experiment, forty arithmetical facts were displayed within two blocks (20 each). Similarly, three options were displayed to answer the operation. 4. Data description. 4.1. EEG recordings. - Baseline: a cross was displayed on the screen, and a 3-min recording was taken for each child. - Reading: children read out loud three texts while the EEG was being recorded. Then, three comprehension questions were answered. - Math: two blocks of 20 operations were performed for each child. 4.2. EEG events. - Baseline: no events. - Reading: reading out loud (between 'condition' events); answers for reading comprehension questions ('33026' option 1; '33027' option 2; '33028' option 3). - Math: block 1 (from '33101' to '33120'); block 2 (from '33121' to '33140'); answers ('33026' option 1; '33027' option 2; '33028' option 3). 4.3.

Steps to reproduce

Technical information - EEG device: gTec- g.USBAMP. - 32 channels. - Online bandpass filter 0.1-100 Hz. - Online Notch filter: 60 Hz. - Sample frequency: 256 Hz - Ground electrode: Fpz - Reference: Left earlobe - O2 electrode was failed during all EEG recordings. The authors suggest eliminating or interpolating this electrode. Participants details - Participants Sub0001 to Sub0087 have both psychometric results and EEG signals. - Participants Sub0088 to Sub0102 only have psychometric results. - EEG data from the reading group that did not complete the three texts were not taken due to technical problems during the signal acquisition (see EEG files.xlsx for further information).
