                      and corresponding questions $(Set_2)$ of the Heard Text
                      Recall (HTR) paradigm as introduced by Schlittmeier et al.
                      (2023). In the HTR, participants listen to short texts and
                      answer nine open-ended questions after each text
                      presentation, allowing for measuring comprehension and
                      memory across various experimental conditions in a
                      within-subject design. The questions are categorized into
                      three types, asking for either names, family relationships,
                      or other factual details. Data from 13 experiments involving
                      429 participants were analyzed to determine difficulty
                      indices for each text (with each text tested a different
                      number of times), each question type, and individual
                      questions. These difficulty indices enable researchers to
                      ensure a balanced level of HTR-task difficulty, which is
                      particularly important for drawing meaningful comparisons
                      between different experimental conditions. This publication
                      serves as an initial reference, and we encourage researchers
                      to contribute further datasets.},
