A method of data collection is presented that unites the efficiency of mass testing with the ease of instant electronic data collection that is typical of computer-based experiments run on individual participants. A wireless response system (WRS), originally designed as a teaching tool, is used to replicate three classic and robust effects from the memory literature (effects of false memory, levels of processing, and word frequency). It is shown that for these types of experimental designs, data can be collected more efficiently (in both time and effort) with the WRS method than through traditional mass- and individual-testing methods alone. The advantages and limitations of WRSs for use in mass electronic data collection are discussed.
