The Psychological Society of Ireland (PSI), Cumann Síceolaithe Éireann, is the learned and professional body for psychology and psychologists in the Republic of Ireland. Since its birth in 1970, the Society has grown from a mere 17 members and now represents circa 5,300 members. The Society was established during a time when psychology as a subject and a profession was in its infancy in Ireland. Since its creation, the members of the PSI have helped shape and develop psychology as a science in Ireland, and their work and commitment have given Irish psychology a voice and standing on not only the European but also the world stage.
The PSI is committed to maintaining the high standards of practice in psychology that have been set by its members since the founding of the Society and also to exploring new and innovative ways of furthering psychology as an applied science.
The PSI is an independently governed, registered charity and our office is located in Dublin 8. Registered Charity Number is 20016524.
What do we do?
When the Psychological Society of Ireland was established its primary objective was the advancement of psychology as an applied science in Ireland and elsewhere. The PSI has helped cultivate a high standard of psychology in Ireland which is visible in both academic and professional settings. These high standards provide psychologists who study and work in Ireland with the qualifications and experience that is needed to gain membership with the PSI.
The symbol of the Society is the Greek letter Ψ which represents the initials of the Society in English namely PSI.
The motto of the Society is "Quanta Est Animi Magnitudo".
Aims and Activities of the PSI
In an effort to further ensure high standards in all areas of psychology in Ireland the PSI has established Divisions for all psychology specialisms and Special Interest Groups (SIGs), membership of which is based on the applicant's experience and qualifications. Each Division or SIG (see Organisational Chart below) deals with a specific area and provides lectures, resources, professional learning and development events, and a voice for psychologists not only within the PSI but within Ireland.
Since its inception, the PSI has had and continues to have, many dealings with various government agencies with the aim of protecting, promoting and furthering the profession of psychology in Ireland.
As well as the work of the PSI Council there are groups and committees who have been undertaking work on behalf of Council.
