3 RESEARCH MODEL AND HYPOTHESES
We conducted a mixed-design lab study with one between- and one within-subject factor, each
with two levels. Two groups (between-subject) with different system descriptions, referred to as
Description (the AI system is worsening performance and increases stress, referred to as negative
verbal description condition vs. the AI system is enhancing performance and decreases stress,
referred to as positive verbal description condition) were investigated. The within-subject
factor for each group was the AI systems’ Status (sham-AI condition vs. no-AI). The order of
conditions was counterbalanced across participants.

We address the following research questions and hypotheses with this design:
