On the use of wireless response systems in experimental psychology: implications for the behavioral researcher.

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.

Picture recognition without picture identification: a method for assessing the role of perceptual information in familiarity-based picture recognition.

The present study examined the claim that unidentifiable test-pictures are processed and recognized on a perceptual, as opposed to a conceptual, level. Using an extension of the recognition without identification paradigm (e.g.
