Step-by-step explanation:
Two important changes in psychological assessment in the past three decades are the integration of neuroscience and computer science, and the use of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a standardized classification system.
The integration of neuroscience and computer science has allowed for advanced imaging techniques and the development of computerized tests to assess brain functioning and cognitive abilities.
The DSM-5 has provided a consistent framework for diagnosing psychological disorders, which has improved the reliability and validity of assessments.
