E-Prime is an authoring package for setting up computerized psychology experiments. It permits precise, low level control of computer hardware to achieve millisecond accurate timing of stimulus presentation and response collection.
Eprime: The Good, the Bad, & the Ugly
Stimulus presentation synchronized with screen refresh with millisecond accuracy
Easier to learn and use than conventional programming languages
Presentation of images, text, and sound
Recording of responses from mouse, keyboard, response box, microphone
Other responses possible using response box interface or parallel/serial port
Able to log timing details of all events and responses into ASCII spreadsheet
E-Prime Biological can "talk" with EGI Netstation 2 for marking events etc.
Can be synchronized with scanner with a TTL level input
Does not run on Windows NT/2000
Cannot present video stimuli
Makes some assumptions about basic experimental paradigm - lacks some flexbility
Can simulate video with rapid single image presentation
Can using scripting to add flexibility
