Update: Metacognition in Psychotic Disorders: Grounds for Therapy?

In 2014, my collaborators and I published a post on Mindwise entitled: “What are you thinking right now? On the topic of metacognition”, in which we discussed what metacognition is considered to be (‘thinking about thinking’) and how metacognition may play a role in different kinds of psychopathology.

Complex grief can be treated

Normally, grieving is a natural process and does not require treatment by psychologists. However, when someone dies in a violent way, the grief process for the bereaved can become complex, and resilience and social support are often not enough.
