Validation of the Pictorial Implicit Association Test
trials were presented first or second, and b) the location of the stimuli on the screen (e.g., faces of men of Moroccan or Dutch descent, or positive/negative images and text on the left/right side of the screen, see Table S3 in supplements for an overview of all task versions). All images were presented in color, and all images were presented a maximum of two times during the two critical blocks.
Equipment
Experiment 2 was conducted online through Qualtrics and by using Iatgen, a pre-programmed survey-software implicit association test (Carpenter et al., 2019). As the original survey software uses words only, we adapted it to work with pictures. Participants using mobile devices such as tablets and smartphones were not allowed to participate in the study.
Procedure
Participants who signed up to take part in the study were sent a link to the tasks.
Via Qualtrics, participants first received brief information about the goal of the study,
namely to compare two types of categorization tasks containing faces and scenes.
They were also told that they would receive more information about the study after
completing the experiment. If participants were still interested in participating, they
signed a digital consent form to allow us to use their data. Next, participants were
issued questions about their age, gender, handedness, native language, and their
own and their parents’ nationality. The study would be terminated with a custom
message if the participants were below of the age of 18, or if they or their parents 7 did not have the Dutch nationality. If participants passed the screening, they were
notified the first categorization task would start when they continued on to the next screen. To keep the online experiment as similar as possible to the PIAT in experiment 1, this was all the information that was given.
Every participant took part in both the WIAT and the PIAT. The order of the IATs was counterbalanced, and in-between each IAT the participant completed the SRS. Between each of the tasks, participants could decide to take a break for as long as they wanted. At the end of the experiment, participants were asked questions about their prior experience with people of Moroccan descent, i.e., whether they knew anyone of Moroccan descent and if they did, how well they knew this person or these persons. This information was not used in subsequent analyses, as it was part of a different research project. Participants were then given a full debriefing on the goals of the study, and were thanked for their participation.
