TL;DR: Results suggest that neural efficiency reflects an (ability-dependent) adaption of brain activation to the respective task demands, and not when comparing tasks with the same person-specific task difficulty.
Journal ArticleDOI
Self-disgust in mental disorders — symptom-related or disorder-specific?
Rottraut Ille,Helmut Schöggl,Hans-Peter Kapfhammer,Martin Arendasy,Markus Sommer,Anne Schienle +5 more

Martin Arendasy,Markus Sommer +1 more
TL;DR: The two-component item construction process has been successful in generation an item pool of construct-valid number series items with known psychometric characteristics with no item loss after the calibration phase.
