Abstract
Accurate, error-free communication is essential for success in many areas, such as eyewitness testimony, human factors design, business, education, and personal relationships. Traditional communication uses similar modalities: Participants communicate by talking or by writing, but not both at the same time with the same addressees. New communicative technologies have broadened this vista. For example, one communicator can speak and the other can type. We tested communicative effectiveness using accuracy and error detection in a trivia recall test, evaluating the roles of presentation and retrieval modalities on reporting facts stored in longterm memory. Heteromodal communication (hearing and writing or reading and saying) was more effective than homomodal communication (hearing and saying or reading and writing), with the most correct responses and the most errors caught. This has direct connections to communicative success and applied tests of skill.
