... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested.

Camacho, Monica J., Steiner, Bruce A. and Berson, Barry L. (1990): Icons vs. Alphanumerics in Pilot-Vehicle Interfaces. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 11-15.

The effects on performance from the use of icons and alphanumerics in pilot-vehicle interfaces were investigated in an experiment. Varying numbers of single status display indicators were presented in both iconic and alphanumeric formats in fixed and random display positions across three levels of difficulty. Subjects' ability to maintain a tracking task while concurrently searching and selecting appropriate display indicators was tested. Results indicated that for all numbers of indicators presented, icons produced faster search and selection reaction times. Significant interactions were also found for format type and difficulty level. Questionnaire assessment revealed that subjects preferred the iconic to the alphanumeric formats. Implications for the design of aircraft interfaces and further research suggestions are discussed.

Steiner, Bruce A. and Camacho, Monica J. (1989): Situation Awareness: Icons vs. Alphanumerics. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 28-32.

This study examined the effect of varying the amount of information that is presented in either an alphanumeric or iconic display and its effect on how efficiently a pilot can utilize the data. The results from 12 subjects, under self-paced presentation length conditions, indicated that for a small quantity of data (2 or 4 bits) there is no difference in response times between iconic and alphanumeric displays. As the quantity of data presented increases (8, 16, or 32 bits), subjects perform better using iconic displays.
