How Does the Lack of Diversity in Psychological Science Research Affect Undergraduate Students?

Psychological science has relied on samples that do not reflect the breadth of human diversity, creating challenges for instructors teaching this science to diverse students who may not see themselves reflected in the science they are supposed to be learning.

The purpose of this study was to use qualitative data to determine psychology students' awareness of research samples, how sample demographics affect them, and how they would like professors to address the lack of diversity.

Focus groups were conducted with undergraduate psychology students (N = 27), and transcripts were analyzed thematically.

Students noticed the lack of diversity in psychology research samples, which impacted their sense of belonging, motivation, and perceptions of the field. They emphasized the influential role of instructors in shaping awareness and called for more inclusive teaching practices. At the same time, a subset of students reported that this issue was not salient to their classroom experience.

Lack of diversity in research shapes students' experiences, including participation, sense of belonging in the classroom, and desire to continue in the field.

Instructors can enhance student engagement by transparently addressing sample diversity and integrating more representative research into their teaching.
