title: Visual Analogue Scale (VAS) - Scanner related stress (MRI experiment)

description: The Leiden Consortium on Individual Development (L-CID) study was founded by Marinus van IJzendoorn, Eveline Crone, Marian Bakermans-Kranenburg and Rutger Engels in 2013. It was developed as one of four work packages of the overarching Consortium on Individual Development (CID). The L-CID study is a large-scale longitudinal intervention study in which 500 families with same-sex twins are followed over a six year period. L-CID has a cohort-sequential design with two cohorts: an early childhood cohort (ECC), aged 3-4 at wave 1, and a middle childhood cohort (MCC), aged 7-8 at wave 1. Annual assessments consist of alternating lab- or home visits during which behavioral and neurobiological data are collected. The collected data allow, among others, for testing which child characteristics shape the effect of (manipulated) environmental factors. The aim of L-CID is twofold: 1. To investigate the development of social competence and behavioral control in children between 3 and 14 years old; 2. To dissect the reason why not all children are equally responsive to variations in the social environment.

The parent and child are given one Etch-A-Sketch board and are instructed to use the board to copy a series of three designs that increase in complexity. The parent and child must work together as one controls the left knob (draws only horizontal lines) and one controls the right knob (draws only vertical lines). The parent and child are allowed a maximum of 5 minutes to complete each design, and participants are told that their accuracy on completing or copying the designs will be checked by the experimenter.

description: Saliva was collected using a cotton swab or a collection device, such as a tube or container (passive drool).
description: In L-CID, the saliva sample was used to measure cortisol. Over the course of the two weekdays (first two days of data collection), parents collected saliva samples from their children at three time-points (after awakening, between 16:00 and 18:00 and 30 minutes after dinner). During year 3 of the Early Childhood Cohort, the saliva was collected by a cheek swab. During the other years, it was collected by requiring the children to spit into a small tube (passive drooling). Parents were asked to store the saliva in the freezer. Once collected, saliva samples were stored at −20° Celsius at the university until they were sent to the laboratory of the University Trier for cortisol analyses.

description: The fMRI - Self-concept Task measures brain activity during the Self-concept Task, in which children are asked whether certain negative and positive traits fit them.
description: The Self-concept Task functional runs were acquired using a T2*-weighted echo-planar imaging (EPI) technique. To ensure stable imaging, the first two volumes, known as dummy volumes, were discarded initially to allow for the equilibration of T1 saturation effects. The imaging parameters used remained constant throughout the waves. The acquired volumes covered the entire brain with a field of view (FOV) measuring 220 mm in the anterior-posterior (ap) direction, 220 mm in the right-left (rl) direction, and 111.65 mm in the foot-head (fh) direction. The imaging protocol employed a repetition time (TR) of 2.2 seconds, representing the time between acquiring consecutive image volumes. The echo time (TE) was set to 30 milliseconds, which indicates the time it takes for the MRI signal to be measured after the radiofrequency pulse. A flip angle (FA) of 80° was used, and the data was acquired sequentially in 37 slices with a voxel size of 2.75 mm x 2.75 mm x 2.75 mm.

description: Functional magnetic resonance imaging (MRI) is a non-invasive technique for examining brain activity. Resting state fMRI aims to assess spontaneous brain activity using MRI while the participant is at rest, not performing any specific task. It captures ongoing functional connectivity patterns within the brain.
description: At the end of the imaging protocol, resting-state data was acquired when participants had their eyes closed. A total of 142 T2-weighted whole-brain echo-planar images (EPIs) were obtained, which included 2 dummy volumes at the beginning of the scan to account for T1 saturation effects. The imaging parameters used for the resting-state data remained constant throughout the waves and were as follows: a repetition time (TR) of 2.2 seconds, an echo time (TE) of 30 ms, and a flip angle of 80°. The field of view (FOV) was 220.000 mm in the right-left (rl) direction, 220.00 mm in the anterior-posterior (ap) direction, and 111.65 mm in the foot-head (fh) direction. The data was acquired in 37 slices.

description: EEG recordings were obtained using a 64-channel hydrocel geodesic sensor net along with NetStation software from Electrical Geodesics, Inc. To ensure children's comfort and avoid fatigue, irritability, and loss of attention, a subset of electrodes was chosen for data collection. These selected electrodes were strategically placed on specific brain regions: frontal (F3, F4), frontotemporal (F7, F8), central (C3, C4), temporal (T7, T8), parietal (P3, P4), occipital (P7, P8), and the mastoids on the left and right sides. Additionally, two electrodes were positioned below the eyes. The EEG signal was amplified using a NetAmps300 amplifier. The reference for the online recording was set to Cz, and the data underwent low-pass filtering at the Nyquist frequency (100 Hz) for a sampling rate of 250 Hz. Throughout the recordings, impedance levels were carefully maintained below 100 kΩ.
