This qualitative study introduces a pedagogic design which addresses the challenging task of teaching and learning self-awareness and critical reflection in the teaching of psychology. The context of the study was a course in personality psychology for first year students, and the topic of interest was how the perception of personality is affected by gender stereotypes. The pedagogic design included the recording of a mixed-sex dialogue, which was then digitally altered for pitch and timbre producing two gender-switched versions of one single recording. Students were divided into two groups who listened to one of the two different voice alterations, and were given the task to rate the personality traits of male or female sounding versions of the same character. In the subsequent debriefing seminar, students were presented with the data from their ratings. These results were then used as a reference point for inter-group discussion, and later students were also asked to reflect over the activity individually in writing. A thematic analysis of their written answers indicates that this pedagogic setup, in combination with guided reflection, can be helpful to challenge students’ own assumptions, aiding self-awareness and critical reflection related to stereotyping.
