Professor of Psychology David c. McClelland '56 sold his 20-year-old business consulting company. McBer & Co., Thursday to a New York based firm, but he will remain is a consultant to the company for the next few years.

Neither McClelland nor officials at the purchasing firm. Yankelovich, Skelly and White, Inc., would disclose the price.

McBer, a company originating from McClelland's studies on achievement motivation, applies his research to management training and job competency analysis.

Florence R. Skelly, president of Yankelovich, said she would call the transaction "a joining of forces," since the companies, which are both involved in marketing, corporate communications and public policy, are computable in style and principles."

Next winter, McClelland hopes to follow up his work by returning to India, where he did the initial achievement motivation research in the 1960s that led to the founding of McBer & Co.
