Chapter 2 on the History of Psychological Testing includes two additions: a brief section on the origins of rating scales, and a short summary of the contributions of Leta Hollingworth to IQ testing in giftedness. Topic 4A, Basic Concepts of Validity, now concludes with brief reference to the overlooked concept of test utility: Does use of tests yield better patient outcomes or more efficient delivery of services? Updates on the WAIS-IV are included in Topic 5B: Individual Tests of Intelligence and Achievement. The section on Learning Disabilities in Topic 5B: Individual Tests of Intelligence and Achievement includes new material on RTI (Response to Intervention), which is rapidly becoming the preferred conceptual approach. The coverage of the Cognitive Abilities Test (CogAT) in Topic 6A: Group Tests of Ability and Related Concepts has been increased, including a presentation of sample questions. In Topic 6B: Test Bias and Other Controversies, new examples of the impact on IQ of test bias, environmental deprivation, race differences, age differences, and generational shifts, have been added. The coverage of the Bayley-III has been significantly expanded in Topic 7A: Infant and Preschool Assessment. Updates on the DAS-II and the DIAL-III are included in Topic 7A: Infant and Preschool Assessment. The coverage of mental retardation (in Topic 7B: Testing Persons with Disabilities) has been revamped to reflect the important shift in terminology to the preferred concept of intellectual disability .

In Topic 8A, Theories of Personality and Projective Techniques, my prior skepticism about the Rorschach has been softened in light of the blue ribbon panel report from the Society for Personality Assessment (which concluded that the inkblot test has validity on a par with other accepted tests like the MMPI-2). Substantial new material on the MBTI and CPI, two instruments widely used in "normal" assessment, has been added to Topic 9A: Assessment within the Normal Spectrum. Topic 9B: Positive Psychological Assessment, is entirely new and includes extended coverage on the assessment of creativity (e.g., Torrance Tests of Creative Thinking), emotional intelligence (e.g., the Mayer-Salovey-Caruso Emotional Intelligence Test), optimism, gratitude, and sense of humor. Topic 10B: Neuropsychological Tests, Batteries, and Screening Tools, includes updating of references on most instruments and addition of the Neuropsychological Assessment Battery, a promising approach that is both comprehensive and modular.

A new section on personality tests such as the NEO-PI-R as a useful basis for employee selection has been added to Topic 11A: Industrial and Organizational Assessment. In Topic 11B: Forensic Applications of Assessment, the section on malingering has been expanded to include the Test of Memory Malingering (TOMM) and the use of the MMPI-2 validity scales in the detection of malingering. A brief section on cognitive disability and the death penalty has been added to Topic 12A: Psychological Testing and the Law. In addition to updating several topics and tests, Topic 12B: Computerized Assessment and the Future of Testing, now includes a closing section on "Testing and the Next Big Questions in Psychology."
