Stroop color-word task

The Stroop color-word task consists of pairs of conflicting word and color stimuli, both being inherent aspects of the same symbols, presented simultaneously, for example a name of one color printed in the ink of another color. The difference in time for reading the words printed in colors and the same words printed in black is the measure of the interference of color stimuli upon reading words.

In NTR projects YC_BS1, YC_BS2, YE_ATTEF2 and YE_COG18, the Stroop color-word task was measured with cards and in NTR project YC_ADHMRI, it was measured through a computerized task.

Measure was collected within the following wave(s):

YC_BS1 Wave

Wave alternate title	Brain Scale measurement 1 YC_BS1, Brain Scale measurement t0, BrainScale age 9
Short description of the wave	The YC_BS1 project was the first measurement in the Dutch longitudinal Brain Scale study in which twins, their siblings and their parents were assessed at three year intervals. YC_BS1 targeted 9-year old twins (mean age = 9.1 years, SD = 0.51 years) born between 1995 and 1996, and their 9-14 year old siblings (mean age = 11.9 years, SD = 1.16 years) born between 1990 and 1997. The main aim of the Brain Scale project was to explore to what extent genetic and environmental factors explain individual differences in brain development and cognition. Data collection included psychometric IQ tests, a comprehensive neuropsychological testing protocol, and parental and self-ratings of behavioral and emotional problems. Physical maturation was measured through assessment of Tanner stages. Hormonal levels (cortisol, luteinizing hormone, follicle-stimulating hormone, testosterone, and estrogens) were assessed in urine and saliva. Brain scans were acquired using 1.5 Tesla Magnetic Resonance Imaging (MRI), which provided volumetric measures and measures of cortical thickness. Buccal swabs were collected for DNA isolation for future candidate gene and genome-wide analysis studies.

YE_ATTEF2 Wave

Wave alternate title	Genetics of attention and executive functioning measurement 2 YE_ATTEF2
Short description of the wave	The YE_ATTEF2 project was the second measurement of a longitudinal study on the source of individual differences of cognition, attention, and executive functioning from preschool to young adulthood. This project included the measurement five years after baseline (YE_ATTEF1) among 12-year old twin pairs (mean age = 12.4 years, SD = 0.14 years) and their 8-16 year old siblings (mean age = 11.97 years, SD = 2.55 years), and additionally recruited new twin pairs and siblings of the twin pairs. Behavioral data were collected with surveys filled in by parents and teachers (Conners, Child Behavior Checklist (CBCL), Strengths and Weaknesses of ADHD symptoms and Normal behavior Scale (SWAN), Teacher Report Form (TRF)) or filled in by children themselves (Youth Self Report (YSR)). To measure pubertal development, children filled in the Tanner questionnaire. Neurocognitive abilities were assessed with computerized ANT tasks, Flanker, Simon and Stroop. IQ was assessed with WISC-R. DNA was collected to determine zygosity and for genotyping SNP’S at candidate gene loci. Saliva was collected to assess cortisol concentrations.

YC_ADHMRI Wave

Wave alternate title	MRI-based research into problem behaviors in twins YC_ADHMRI
Short description of the wave	In the ADHD-MRI project, the genetic and environmental influence on ADHD related neurobiological changes were investigated in monozygotic twins (mean age = 14.9 years, SD = 1.2 years) who were born between 1986 and 1993. Twins were selected based on their Child Behavior Checklist Attention Problems (CBCL-AP) scores obtained in the regular YNTR survey waves and divided into three groups: discordant pairs (one affected, one unaffected), concordant pairs (both affected) and control pairs (both unaffected). To determine the presence of ADHD, mothers of the participants were interviewed with the Diagnostic Interview Schedule for Children (DISC-IV). Additionally, they filled in two behavioral questionnaires (CBCL and Strengths and Weaknesses of ADHD Symptoms and Normal Behavior (SWAN)). The twins filled in the Youth Self Report (YSR). Based on the outcome of the interview and questionnaires, twin pairs that were found eligible for the MRI experiments were invited. Both structural and functional MRI (color-stroop and flanker tasks) were performed. DNA was collected to confirm zygosity.

YE_COG18 Wave

Wave alternate title	Cognitive abilities of 18-year-old twins YE_COG18
Short description of the wave	The YE_COG18 project is the fifth measurement of a longitudinal study into the development of intelligence and problem behaviour (waves one and two not included in this catalogue, wave 3: YE_COG10, wave 4: YE_COG12), to which additional participants were recruited (twins with siblings and their parents). It targeted 18-year old twins (mean age = 18.1 years, SD = 0.5 years) born between 1986 and 1991, their 8-35 year old siblings (mean age = 18.8 years, SD = 4.9 years) born between 1970 and 1998, and their parents (mean age = 48.9 years, SD = 4.14 years) born between 1942 and 1965. The test protocol consisted of a physical part and a psychological part. Physical measurements included cardiovascular functioning (assessed with the VU-AMS device), a physical examination with basic anthropometric measurements and the collection of saliva, DNA and fingerprints. The psychological part consisted of a series of cognitive tests that measured the following abilities: intelligence (Wechsler Intelligence Scale for Children, WISC-R or Revised Amsterdamse Kinder Intelligentie Test, RAKIT); inhibition (Stroop); spontaneous production of words (Verbal fluency); verbal learning and memory (California Verbal Learning Task, CVLT); emotion recognition (Reading the mind in the eyes); perceptual speed (Π inspection time task); spatial short term memory (n-back task and Corsi block tapping task). Furthermore, some questionnaires were administered to the participants (Autism-Spectrum Quotient, Tanner self-report), mothers of the twins (Social Responsiveness Scale) and research assistants (Test Observation form).

notes	The Stroop color-word task consists of pairs of conflicting word and color stimuli, both being inherent aspects of the same symbols, presented simultaneously, for example a name of one color printed in the ink of another color. The difference in time for reading the words printed in colors and the same words printed in black is the measure of the interference of color stimuli upon reading words.

To determine the presence of ADHD, mothers of the participants were interviewed with the Diagnostic Interview Schedule for Children (DISC-IV). Additionally, they filled in two behavioral questionnaires (CBCL and Strengths and Weaknesses of ADHD Symptoms and Normal Behavior (SWAN)). The twins filled in the Youth Self Report (YSR).

It targeted 18-year old twins (mean age = 18.1 years, SD = 0.5 years) born between 1986 and 1991, their 8-35 year old siblings (mean age = 18.8 years, SD = 4.9 years) born between 1970 and 1998, and their parents (mean age = 48.9 years, SD = 4.14 years) born between 1942 and 1965. The test protocol consisted of a physical part and a psychological part. Physical measurements included cardiovascular functioning (assessed with the VU-AMS device), a physical examination with basic anthropometric measurements and the collection of saliva, DNA and fingerprints. The psychological part consisted of a series of cognitive tests that measured the following abilities: intelligence (Wechsler Intelligence Scale for Children, WISC-R or Revised Amsterdamse Kinder Intelligentie Test, RAKIT); inhibition (Stroop); spontaneous production of words (Verbal fluency); verbal learning and memory (California Verbal Learning Task, CVLT); emotion recognition (Reading the mind in the eyes); perceptual speed (Π inspection time task); spatial short term memory (n-back task and Corsi block tapping task). Furthermore, some questionnaires were administered to the participants (Autism-Spectrum Quotient, Tanner self-report), mothers of the twins (Social Responsiveness Scale) and research assistants (Test Observation form).', 'wave_end_date_collection': '2006-01-01', 'wave_language': 'NL', 'wave_physical_data_product_description': 'Data collected through paper-and-pencil surveys have been scanned.
