A study is presented that examines the influence of print and online catalogs on consumer information processing. Petty and Cacioppos (1979) elaboration likelihood model and research from the field of human-computer interaction are used to hypothesize differences in consumer information processing when exposed to retail catalog information via print and online communication modes. Theory suggests, and results support, that a print catalog is more effective at stimulating cognitive elaboration and positive affect than a direct extension of the print catalog online. Implications for academics and practitioners are discussed. 2002, Taylor & Francis Group, LLC. All rights reserved.
