Sigmund Freud’s perspective on personality development is seminal in many respects. Outlining the existence of the conscious, preconscious and subconscious was a revolutionary theory, but was much discredited in his day (Ryckman, 2013). Today, in neuro-science, we can see the working of the unconscious in the  brainstem. The brainstem can activate both movement (Donnelly, 2014) and panic reactions (hysteria) outside of conscious awareness  (Šilhán,  Jelínková, Walter, Pavlov Praško, Herzig,  Langová & Školoudík, 2015).

Freud’s partial understanding of the effects of early childhood trauma on development is also foundational (Ryckman, 2013).  Impulsive aggression which was a big part of Freud’s theory of the id, has now been related to childhood adversity and its effects on serotonin systems in the brainstem. Many personality characteristics are now seen as brain based reactions.

Freud started his work in the field of biology as a doctor and neurologist in the early 20th century (Ryckman, 2013). Only in recent times have we had the tools to find the real home of the id, as well as, the traumatic factors in early childhood that affect development.

Hi to everyone who reads this blog. 
I took more than a year off blogging to get on with my doctorate in neurodevelopment. But as I was slaving over another Discussion Question, I had a thought....Why not use these DQs for the blog? So the topics will be far flung, but I am famous for making most DQs about neurodevelopment. Enjoy and comment!
