Mental Hygiene: The Dynamics of Adjustment* by Herbert A. Carroll, Ph.D., is a foundational mid-century psychology text originally published in 1947, with this revised second edition released in 1951. Designed for college instruction, Carroll’s work focuses on emotional health, self-understanding, and the psychological principles underlying adjustment to life’s challenges.

A blend of theory and practical application, the book addresses motivation, learning, and personality development within the framework of “mental hygiene” — a term popular in early psychology referring to proactive mental well-being. Carroll, a professor at the University of New Hampshire, aimed to make complex psychological concepts accessible to students and educators alike.

An engaging collectible for those interested in the evolution of psychology, education, or mental health awareness during the postwar era.
