Neuro-Physiological Psychology


The Institute for Neuro-Physiological Psychology (INPP) was established in 1975 by psychologist Peter Blythe, PhD., with the aim of researching the effects of immaturity in the functioning of the central nervous system on learning outcomes, emotional wellbeing and behaviour. Since that time, applying standardised tests originally used in medicine, INPP has developed reliable methods of identifying and assessing signs of neuro-motor immaturity (NMI) in children and adults, and developed non-invasive methods of intervention.

NMI describes the omission or arrest of a stage of early development. Every normal, full-term baby is born with a set of primitive or survival reflexes that are inhibited or controlled by higher centres in the brain during the first year of life. If these are not inhibited at the correct time, they remain active in the body and can interfere with balance, motor control, eye functioning, eye-hand coordination and perceptual skills. Uninhibited reflexes can also result in behavioural symptoms such as frustration, hyperactivity and hypersensitivity, and failure to match performance to ability.

There are several primitive reflexes that might be involved in specific learning difficulties and behavioural problems. More than two abnormal reflexes must be present before a diagnosis of NMI is considered. The presence of these is initially assessed through completion of a Child Screening Questionnaire. Research has shown that a score of 7 or more 'yes' answers on the questionnaire indicates that further investigation for underlying neuro-motor immaturity is advised for children over 7 years of age.

Sally Goddard Blythe MSc. (Psych) is the Director of INPP international. She trained at the INPP in 1987/88 and joined the permanent staff in 1988. Since that time she has written numerous articles and papers on neuro-developmental factors in educational difficulties. She is the author of several books published in more than 6 languages on aspects of child development, including professional manuals for teachers, clinicians and health practitioners and books for parents. Her time is divided between clinical practice of the INPP Method based in Chester (UK), lecturing, writing and overseeing research projects involving the INPP Method.


The INPP Method

The INPP method is practiced in over 20 countries around the world and has helped change the lives of thousands of children, adults and families since its early development in 1975.

At Connect Movement Therapy, we offer through neurodevelopmental therapy the opportunity for each person to achieve the highest level of functioning that is possible for them. We offer the INPP Method to address neuro-motor immaturity in children over 7 years of age. The INPP Method is based on over 45-years of pioneering research, expertise and practice investigating and helping children to resolve physical factors underlying learning and behavioral problems. It is a completely non-invasive program using an individualised movement therapy program that is tailored to help a child succeed. INPP's evidence-based research and results demonstrate how the method can help children to overcome many types of difficulties.

For a child assessed with retained reflexes, the INPP Method works to inhibit those reflexes. This inhibition allows for the developmental building blocks that were missed in the early stages of life to have a second chance. The program implements a non-invasive technique of assessing and addressing developmental immaturity, to support and enhance the foundations for learning and daily functioning.

The INPP Method can assist children in overcoming difficulties associated with:

  • Attention and concentration
  • Reading, writing, spelling and maths
  • Clumsiness and restlessness
  • Coordination and balance (including sports activity)
  • Inability to self-regulate
  • Dyslexia, dyspraxia, ADD
  • Anxiety and panic disorders

If you think that the INPP Method can benefit your child, you can contact us using one of two options. The first is to complete a Child Screening Questionnaire (available from the link below), which assists us in determining if this is the right program for your child. Once we have received your submitted questionnaire, we will contact you in 1 to 2 business days. The second is to submit a general enquiry of interest using the form on our Contact page. Once again, we will be in touch with you in 1 to 2 days.



Standardised neurological testing that is used to identify underlying problems of neuro-motor and sensory immaturity. Conducted over a 2-3 hour time, typically completed in a single session. For special considerations, may be completed across two appointments.



Following the diagnostic assessment, a detailed Educational Report based on the neuro-motor analysis is written and shared with clients.



Based on the reflex profile, an individual program is developed. Detailed exercises are given to be carried out at home. The exercises take no more than 10-15 minutes of time per day. Follow-up assessments are scheduled for every 4-8 weeks after the first session.

To determine suitability for the INPP Method, a screening questionnaire is required. The responses given on the questionnaire, along with other information discussed in consultations, will help determine suitability. A score of 7 or more 'yes' answers on the questionnaire indicates that further investigation for underlying neuro-motor immaturity is advised for children over 7 years of age.
