Psychological evaluation
Modern "Psychological evaluation" has been around for roughly 200 years, with roots that stem as far back as 2200 B.C. It started in China, and many psychologists throughout Europe worked to develop methods of testing into the 1900s. The first tests focused on aptitude. Eventually scientists tried to gauge mental processes in patients with brain damage, then children with special needs.
Positive psychology
The term positive psychology dates back at least to 1954, when Maslow's first edition of "Motivation and personality"  was published with a final chapter titled "Toward a Positive Psychology." In the second edition (1970), he removed that chapter, saying in the preface that "a  positive psychology is at least available today though not very widely." There have been indications that psychologists since the 1950s have been increasingly focused on the promotion of mental health rather than merely treating mental illness.
