The IB Psychology course looks at behaviour through three different approaches: biological, cognitive and sociocultural.  In modern psychology it is understood that these three approaches interact rather than compete to explain behaviour.

This chapter looks at cognitive explanations of behaviour.  There are two cognitive processes that are studied in this unit: memory and thinking.  The HL extension looks into the question of how modern use of technology may be changing the way we think and remember.

Each chapter is divided into smaller sections with quizzes to test for mastery of key vocabulary and "checking for understanding" questions with sample answers to check for broader conceptual understanding.

I would like to thank Aidan Carr from St Joseph's Institution International in Singapore for his assistance in writing the sections on thinking and decision making - and cognitive processing in the digital world.
