Welcome to Psychology at CMU. With nearly 30 award-winning faculty and almost 150 people in total, we are a vibrant community whose research continues our Department’s 100 year tradition of studying the deeper mechanisms and processes underlying human behavior and its neural bases. Innovation is in our DNA: our department has been at the center of helping create new scientific initiatives in artificial intelligence, cognitive science, neural-nets, and, more recently, university-wide efforts in brain research and the science of education .
In many disciplines, Western methods of conducting research are predominant.  Researchers are overwhelmingly taught Western methods of data collection and study. The increasing participation of indigenous peoples as researchers has brought increased attention to the lacuna in culturally-sensitive methods of data collection. Non-Western methods of data collection may not be the most accurate or relevant for research on non-Western societies. For example, " Hua Oranga " was created as a criterion for psychological evaluation in Māori populations, and is based on dimensions of mental health important to the Māori people – "taha wairua (the spiritual dimension), taha hinengaro (the mental dimension), taha tinana (the physical dimension), and taha whanau (the family dimension)". 
The process of peer review involves evaluation of the experiment by experts, who typically give their opinions anonymously. Some journals request that the experimenter provide lists of possible peer reviewers, especially if the field is highly specialized. Peer review does not certify correctness of the results, only that, in the opinion of the reviewer, the experiments themselves were sound (based on the description supplied by the experimenter). If the work passes peer review, which occasionally may require new experiments requested by the reviewers, it will be published in a peer-reviewed scientific journal . The specific journal that publishes the results indicates the perceived quality of the work.
