Dear colleagues,
You are cordially invited to the Institute’s seminar featuring a talk by David Lacko, Beáta Sobotová, Anna Kubelková, and Anna Lázníčková from the Institute of Psychology of the Czech Academy of Sciences entitled “Intergroup Polarization and Prejudice: Advances in Measurement and Modeling.”
The presentation will introduce the research agenda of the Brno Lab of Intergroup Processes (BLIP) and present several of its ongoing projects, including two GAČR and two OP JAK grants. Particular attention will be devoted to the PRINS project, which examines whether and how intergenerational contact can reduce attitudinal and affective polarization between parents and grandparents. Using advanced longitudinal analyses of SOEP data alongside original three-wave panel data, the project investigates the role of children’s presence, grandparental childcare, and children’s age in shaping changes in polarizing attitudes.
In the second part of the seminar, the speakers will present findings from two studies conducted within a GAČR project focusing on the measurement of prejudice. The first study is a systematic review of 263 studies (1951–2024) examining the psychometric properties of instruments measuring racial and ethnic prejudice, highlighting substantial gaps in evidence regarding temporal stability, measurement invariance, predictive validity, and overall construct validation. The second study is a 2×2 experiment (N = 268) testing the robustness of reaction-time modeling across administration modes (online vs. laboratory) and item formats (single vs. multiple items). The results demonstrate practical invariance of latent trait estimates across modes while also identifying differences in perceptual and pre-decisional processing.
The seminar will be in English.
