This study examined test-related experiences of enjoyment, anger, anxiety, and boredom in a sample of 2059 German school students (50% female) from grade 6, and how they relate to students' abstract reasoning ability (ARA). Emotions were assessed immediately before, during, and after a mathematics achievement test. Analysis of variance showed that emotions experienced during the test situation differed based on students' ARA level, with correspondence analysis revealing substantial differences between the emotional profiles of different ability groups. Enjoyment proved to be most prominent in students with high ARA, whereas anger and anxiety were predominant for students with low ARA. Boredom was found to be highest among students in the intermediate ARA group. Implications for research and practice are discussed.
