Dear PsyToolkit users,
Thank you for this forum! I am curious to hear if anyone has experience with creating basic auditory reaction time tests in Psytoolkit? Specifically, I struggle with latency issues related to stimulus presentation. This is of course a well known problem across all types of software, but currently I get RT latencies well above 500 ms and I was hoping to be able to bring that down. Perhaps more importantly, I would be curious to hear of any (creative?) solutions to measuring such latencies in auditory as well as visual stimulus presentation.
I am using a simple variation (see below) of the code used to run the (visual) Deary-Liewald test (available in the library). I have tried calling .wav as well as .mp3 files.
options
set &maxResponseTime 3000
set &minInterval 1000
set &maxInterval 3000
sounds
sound pinknoise.wav
task dl_task_simple_aud
keys space
draw off
show background 0 0 100
show bitmap box_cross
draw on
set $randomdelay random &minInterval &maxInterval
delay $randomdelay
sound sound
readkey 1 &maxResponseTime
clear 3
save BLOCKNAME &training $randomdelay RT STATUS
block dlsimple_aud_real
set &training 0
message readyrealdansk
tasklist
dl_task_simple_aud 20
end
Any comments or suggestions would be much appreciated.
Thanks very much.
Cecilie
