Figure 1. Schematic presentation of the study. The left half illustrates the “human-first” approach, whereas the right half depicts the “GenAI-first” approach. As shown, this study focused on the former approach, with Letter 4 (generated through the GenAI-first approach) used solely as a positive control. The dotted square indicates Letters 1-4, highlighting their relationship to the human-first and GenAI-first approaches.
