Constructing test items for standardized tests of achievement, ability, and aptitude is a task of enormous importance. The interpretability of a test's scores flows directly from the quality of its items and exercises.

The aim of this entire book is to increase the test constructor's awareness of this source of measurement error, and then to describe methods for identifying and minimizing it during item construction and l...
This textbook aims to provide a selective, but representative, review of work in cognitive development, grouped around themes that are familiar from textbooks of adult cognition.

Over the years, systemic? therapists have theorized extensively about the client family as a system and have more recently addressed the use of self in therapy, but there has been very little attention paid to the therapeutic relationship between the two.
