The process of psychotherapy and counselling involves addressing multiple domains of functioning – physiological arousal (stress levels), movement and senses, attachment, emotion, and cognition. Throughout evolution our brains have developed both primitive and advanced information processing systems that have different styles of perceiving and does so at different speeds.
The level of complexity of our brains makes us very susceptible to dysregulation, dissociation, and errors in thinking and judgement. Although evolution selects adaptations based on survival, this is done only in the short-term view of survival to adapt to the present environment. It does not account for a future strategic plan of survival and adaptability.
