The article deals with interdisciplinary aspects of learning in the case of physics and psychology. It describes the lab-based academic course focused on: observation and experimentation; discovery of new scientific facts; measurement; identification of errors; the study of psychological characteristics of people (time perception, the reaction time, thresholds). The above techniques are commonly used by both physicists and psychologists. Students are interested in these topics. They are very important, but are excluded from traditional physics and psychology courses.
