Auditory list members may be interested in a new release of Presentation, version 0.40. Presentation is a Windows 95/98/ME/2000 program for stimulus delivery and experimental control that delivers visual and up to four independent sound sources with sub-ms temporal precision that is verified for each stimulus and response event. Version 0.40 adds Presentation control language that simplifies experiment development and that permits stimuli to be modified in real-time based on behavioral responses. As a result, Presentation 0.40 supports a full complement of adaptive psychophysical procedures (e.g., two alternative forced choice, threshold determination, etc.). Presentation 0.40 can also use parallel and serial inputs for stimulus control, and can output control pulses to permit PCs to automate behavioral conditioning procedures. Presentation 0.40 permits physiological responses to control stimulus delivery. For example, Presentation 0.40 can assist in defining neuronal receptive fields by changing stimuli to optimize neuronal discharge rates and can change stimulus position in real-time based on changes in head or eye position. A free version of Presentation 0.40 (expiration date: January 2002) is available for download at David L.
