In the late 19th century, psychology emerged as a discipline distinct from philosophy, accompanied by increased efforts to measure and classify human behavior. Psychological testing is one way to measure psychological constructs and behavior. Though testing may be useful in many domains, such as in mental health diagnosis or educational settings, in organizational psychology, the primary catalysts for the development of valid tests of individual differences were the selection and placement of individuals into proper work roles. The invention of new statistical techniques, such as factor analysis and item response theory, has led to improvements in the structure and utility of tests.

To prepare for this Discussion, select two events from the timeline of tests and measurement history that are particularly relevant to industrial and organizational psychology. Research the events you selected and consider how they influenced the development of tests and measurement.

With these thoughts in mind:

Post by Day 3 a brief description of the two historical events you chose. Explain how these historical events influenced the development of tests and measurement. Then, choose one of the two events and describe an historical example of test misuse and its consequences related to the event.

Be sure to support your postings and responses with specific references to the material. APA format.
