“Primates of Park Avenue,” a memoir on the secluded lives of Upper East Side wives, set off a rush of skeptical commentary over what appeared to be the outré rituals, like “wife bonuses,” of New York’s wealthy elite.

On Sunday, after a report that there were factual errors in the book, the publisher, Simon & Schuster, said it would append a note to future editions of the book, written by the social researcher Wednesday Martin, clarifying that some of the memoir’s details and chronologies were changed.

“It is a common narrative technique in memoirs for some names, identifying characteristics and chronologies to be adjusted or disguised, and that is the case with ‘Primates of Park Avenue,’ ” said Cary Goldstein, vice president and executive director of publicity at the publisher.

“A clarifying note will be added to the e-book and to subsequent print editions.”

In her book, Ms. Martin claims to have spent six years living with her two children on the Upper East Side, conducting fieldwork for her memoir. But an article in The New York Post claimed on Sunday, citing property records, that she had lived in her Park Avenue apartment for only three years.
