A group of interconnected consoles for the selective anonymous transmitting and receiving of keyboard responses between the members of a group. The consoles are adaptable to a variety of group communication situations including testing, training, education, and evaluation. Each console includes a plurality of depressable keys in the form of a keyboard, and an illuminatable lamp associated with each key position. When a key is depressed, the associated lamp illuminates to indicate the recording of a response. Each console also includes a first switch to select a mode for transmitting keyboard responses and a second switch to select a mode for receiving keyboard responses. Each group member may perform one or more of the following functions: a) depress one or more keys to record his response to printed instructions adjacent each key; b) select the transmit mode to transmit lamp illuminating signals representing each depressed key to associated lamps on each of the other consoles operating in the receiving mode; and/or c) select the receiving mode to receive lamp illuminating signals representing depressed keys on each of the other consoles operating in the transmit code. Group members may thus transmit and receive keyboard responses from one another. The group member electing to receive lamp illuminating signals observes a lamp illuminate for each key position corresponding to a depressed key on the transmitting keyboard but cannot associate the appearance of an illuminated lamp with another group member. Thus, each group member choosing to transmit evidence of his keyboard responses has a reasonable assurance of anonymity.
