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.
