Why does the same research question yield different estimates in a cross-sectional study, a two-wave panel, a daily diary, and a decade-long cohort? The book builds the answer from research design and measurement through mixed-effects models, structural equation models, intensive longitudinal methods, and dynamic systems, keeping one distinction in view throughout: variation within a person over time versus variation between persons.

The Book of Intelligence: A Complete Guide to Human Intelligence
A popular-science account of human intelligence that is rigorous underneath: what intelligence is and is not, from Galton and Binet to the g factor, CHC theory, and multiple intelligences; how it is measured and how measurement can mislead; genetics, development, the brain, and the uses and abuses of testing; and why humility is the right final chapter.
The Science of Psychological Testing: Concepts, Measurement, and Inference
A textbook on psychological testing written for university courses in Taiwan, developed alongside the author's own Psychological Testing course at NCCU. It treats testing as a scientific practice: what a construct is, how a score is produced and what it can and cannot support, reliability and validity as arguments rather than numbers, and how test results are used responsibly in education, clinical, and organizational settings.
