Conscious thought is not always focused on immediate sensory input and instead is often directed to information that arises from intrinsic changes that occur within an individual. Such self-generated thoughts occupy upwards of half our lives, and are experienced as daydreaming, mind-wandering and in extreme conditions as intrusive thoughts. Although the last decade has seen a rapid increase in studies exploring self-generated thinking, we currently lack an integrative framework for understanding these experiences from both neural and psychological perspectives. The current talk will describes a component process view of self-generated thought that provides insight into the neuro cognitive mechanisms through which this ubiquitous experience contributes to our daily life.
