Query: An Impactful, Classic Book

Those interested in the history of the contemporary study of attention should start here. Broadbent's ideas shaped much of the research on attention in the 1960s and beyond.Note that book is still available through the American Psychological Association (APA) as a print-on-demand paperback book for about $50 (see the APA Books section of APA Online).No sense buying a marked-up old used copy for a good deal more money from a rare book seller.
