Welcome to this professional resource for psychologists

The Psychology Wiki started on 21st January 2006 and had over one million visitors in 2008 alone. It continues to grow steadily and has had over 50000 users a week. This is a trade-a-fact website so please help us by contributing. See the To Do page for ideas. It really is easy to help once you get started!

How to use the site

  1. You can access articles by following the links above in the Foundations and Applied psychology columns. From either column, you are no more than six clicks away from any article. This is a good way to explore the site.
  2. You can use the extensive search capabilities of the site by entering a term into the search box in the left side bar.
  3. You can browse through various categories and subcategories.


The rationale for this site follows from our judgement that whatever the considerable merits of Wikipedia, it could never gain the full support of the academic and professional members of the discipline of psychology as an approved information source.

Yet the technology holds out great promise for centrally consolidating information in the science, providing a conduit for authorative information for academic and applied training, and continuing professional development, as well as providing a vehicle for informing the general public about our discipline.

By developing a specialist site for psychology we hope to win the support of the national psychology societies, and through them to develop a mechanism of appropriate peer review of all articles and to restrict contributors to those with professional qualifications. This will allow articles to achieve academic status for referencing purpose and eventually ground the content solidly in the knowledge base of the discipline.


We aim to provide an up-to-date, authoritative statement of knowledge, theory, and practice in the whole field of psychology. The site is written to serve both staff and students of our academic community, to inform professionals, both in training and in the field, and to provide information for the people we seek to help.

By using the latest collaborative editing software we have built a new kind of knowledge structure for our science that can be shaped and maintained, to the highest academic standards, by our profession as a whole.

We aim for factual accuracy and all articles should be properly referenced. We also aim to be a forum for ideas, so on each discussion page we encourage alternative opinion, proposals for hypotheses requiring verification, practitioner reports, user views, etc.

For how this might be achieved see the Psychology Wiki program of works.

If you were looking for it, here is an introduction to psychology.


The Psychology Wiki founders, administrators, and editors make no money from this site. It is an entirely voluntary operation, disseminating copyright-free psychology information. Our goal is to share, without costs of any kind, psychology knowledge between academic and professional psychologists and with a wider audience of non-psychologists.

The Google advertisements in the right hand pane on your screen are part of the business funding model of Wikia Inc.. As a new form of publisher, they host the wiki (and hundreds of others), providing the technical facilities, bandwidth, storage, backup, and technical support for free. Their declared intention is to do this in perpetuity, the company making its profit via the advertisements. Wikia was set up jointly by the founder of Wikipedia and a long-time WikiMedia board member, as another approach to making knowlege available, without cost to contributors or readers.


Please Note:
Psychology and medicine are changing sciences and not all therapies are clearly established. New research changes treatment and therapy recommendations daily. The contributors to the Psychology Wiki have used their best efforts to provide information that is up-to-date and accurate and reflects generally accepted academic standards at the time of publication. However, as our science is constantly changing and human error possible, the contributors to this article do not warrant the information as accurate or complete, nor are they responsible for omissions or errors in the article or for the results of using this information. The reader should confirm the information in this article from other sources prior to use. See full disclaimer for further statement.
