Human behaviour can be studied using three different Psychological approaches: Biological, Cognitive and Sociocultural. The principles behind these three approaches comprise the common core material for Standard and Higher Level students. Higher level candidates explore an extra element to each of these in the effects of digital technology on thinking and memory and the merits and problems with studying animals in psychology. Student’s will develop a strong understanding of the different research methods used in psychology with HL candidates taking a specific paper applying their knowledge of this. Research methods knowledge will be applied in the Internal assessment where students will design their own experiments investigating an aspect of the Cognitive approach that they have studied.
