With apologies to Freudian pop psychologists, inquiring about a user’s relationship with his mother is not likely to yield useful information for instructional design. Post modern scream therapy, on the other hand, may make users of a broken instructional system feel better for a short time. I have certainly screamed at WebCT over the last 4 years, yet I never detected an improvement in the design.
Research in cognitive psychology aims at discovering the ways in which people think: how they absorb, process, retain, and disseminate information, and how they use that information to make decisions. Understanding the principles of cognitive psychology benefits the designers of instructional systems. The findings from cognitive research can help designers issue products that benefit the user by taking advantage of his or her preferred learning style. Since an institution is likely to use only one instructional system (at a time [most of the time]), students with distinct learning styles from each other are likely to use the same system. Designers need to account for diverse learning styles, and give users the right to set preferences according to their own taste or need. More importantly, designers need to provide a product that does not inhibit a user with bugs that inhibit learning, or engender frustration.
