In the non-imagery direction group, participants were provided with a brief description of the current experiment on the recruitment page. The participants were then provided a link, which directed them to the experiment page. After reading and signing the consent form, they continued to the experiment.
All participants first took a pretest where they were randomly assigned to read one of the moral dilemma scenarios in English and answer a yes-no moral dilemma question of if the action of pushing the elderly passengers off the lifeboat to save yourself and others was acceptable or not. Then participants were asked to fill out the NTQ based on the pretest moral dilemma scenario they read.
For the posttest, the participants were assigned to the other moral dilemma scenario. They took an identical procedure as the pretest condition, where they answered a moral dilemma question and filled out the NTQ. Participants then completed the short English proficiency test and filled out a short demographic questionnaire.
The imagery direction group was recruited with the exact requirements of the non-imagery direction group. This group also had an identical procedure, except before the posttest condition, participants were required to read and listen along with the audio mental imagery instructions based on Gambrell and Koskinen (1986)’s study.
