LabVIEW vs. E-Prime

[Peter Quain]

i thought that the key selling point of specialised stimulus 
presentation software is low level routines - probably written in C 
or C++ (?) - that optimise interaction with the OS (and thus  its 
devices) to provide millisecond precision timing accuracy for the 
higher level routines that organise the stimulus properties and 
collect responses. A programmatic interface to these higher level 
routines makes their manipulation easy and powerful (if you can work 
out where to put dots, and the like :), but it doesn't touch the OS interface.

I'm wondering whether you could be confident that standalone 
applications built in C etc could provide that sort of accuracy 
without a hell of a lot of testing and modification of the OS 
interface routines, and then tuning them on individual machines.

Same basic question with LabView (i thought it was a data 
acquisition, processing tool, with a GUI and a maths language), and 
MatLab (data manipulation tool, full script interface). Can you build 
stimulus presentation paradigms in these applications ..track 
blanking signals properly for example? Could you check easily their 
performance on different machines? We've identified some substantial 
timing errors in a couple of paradigms written in C++. On the other 
hand, our e-prime data from visual paradigms shows that on an 
appropriate machine e-prime can perform as pst state. If you went 
this way, could you trust the timing?
