This free 8 hour course covers some of the main ideas that are central to child psychology, with a particular focus on early development.
Childhood is a time of rapid growth and development and studying these changes is endlessly stimulating. In this 2014 study unit from The Open University, you will be introduced to the discipline of child psychology and some of the key questions that guide the understanding of childhood. These questions include ‘What influences children’s development?’ and ‘How do psychologists study the physical and cognitive changes that occur during childhood?’ As you work through this material, you will also gain a deeper understanding concerning how psychologists work with young children across a range of applied settings through activities and audio-visual materials.
