Eligibility
Inclusion criteria
Inclusion criteria: - Normal or corrected vision - Sufficient knowledge of German at a minimum of CEFR level B2 - Healthy control group: neurologically and psychologically inconspicuous adults without any diagnosed psychiatric and neurological disorders - ADHD group: An ADHD diagnosis must be supported by a suitable document. Acceptable documents include, for example, a medical or psychological diagnostic report, a clinical report, a medical certificate, a doctor’s letter, or a medication plan or prescription for an ADHD-specific medication. If no such document is available, the study coordinator is to be contacted; mild to moderate mental health comorbidities, in particular mood disorders and anxiety disorders, are permitted
Exclusion criteria
Exclusion criteria: - Diagnosed dyslexia or dyscalculia, - Severe psychiatric disorders (e.g. schizophrenia or severe affective disorders), - Acute mental health crises, - Neurological conditions (including visual impairments such as visual field defects or achromatopsia (colour blindness)) - Current alcohol or drug addiction - Insufficient German language proficiency (below CEFR level B2). - If two pairs of glasses must be worn one on top of the other, this will result in exclusion
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - Reading behaviour (e.g. reading speed in words read per minute, eye-tracking and mouse-tracking data) - Reading comprehension (e.g. correctly answered comprehension questions) - Text difficulty (Single Ease Question) - Perceived concentration performance (self-assessment scales (from 0% to 100%)) - Mental workload (NASA-TLX) - Eye-tracking-based core parameters (e.g. fixation duration and regressions) | — |
Secondary
| Measure | Time frame |
|---|---|
| - Demographic data (age, level of education, occupation) - Medication (type of substance, dosage, time of intake) ADHD screening (ASRS 1.1 to assess symptom severity, the APSA to retrospectively assess concentration ability over the last four weeks) - Information on reading habits (FDZ scale, ARHQ) - Information on sleep quality and duration using the PSQI - Subjective and physiological parameters (mental workload using the NASA-TLX, current concentration and subjective usefulness of visual support on self-assessment scales (from 0% to 100%)) - Multimodal neurophysiological data collection (recording of EEG data for the analysis of time- and frequency-based markers (theta/beta ratio and alpha power), eye-tracking data (gaze behaviour, fixation parameters, head movement), ECG data (e.g. heart rate variability as an indicator of physiological stress) and motion data (hand and foot movements) to measure motor restlessness) - Preference ranking of the experimental conditions and open feedback from participants on the perceived effectiveness of the visual support methods | — |
