A bottleneck with an emphasis on a negative emotional reaction to the content of the lecture or the methods used. It may be about the negative emotional reactions of students to either the processes of the course (e.g. students are upset that the work in this course does not match what they did in high school courses in the discipline) or to its subject matter (e.g. some of the findings in the discipline are at odds with things students were taught as they were growing up).
Some bottlenecks are a combination of both emotional and cognitive bottlenecks.
An example of an emotional bottleneck: Resistance to learning research methods - Decoding the Disciplines
