Running Audio simultaneously with Sketchpads

Dominique_L

I'm having trouble getting my audio files (I've tried both .ogg and .wav) to play while simultaneously pulling up a sketchpad. I'm doing this in order to provide audio/visual instructions for participants who cannot read.

Here is OS script behind the controls:

set flush_keyboard yes
set end_after_item ""
set duration 7000
set description "Run items simultaneously"
run instructions_A_audio end=0 runif=always start=0
run instructions_A_fixdot end=100 runif=always start=100
run instructions_A_neutral end=2000 runif=always start=2000
run instructions_A_left end=3500 runif=always start=3500
run instructions_A_right end=4750 runif=always start=4750
run Ready_A end=6000 runif=always start=6000

Any tips are HIGHLY appreciated!

Hi Dominique,

I'm a little confused why the visual instruction is necessary if your participants can't read? It would be easier if you just gave oral ones (maybe even yourself, rather than a recording).
In way, the easiest solution is using a sequence of sketchpads and samplers (see attached scaffold experiment). The sketchpads have a duration of 0, the sampler have a duration of how long you want to present the sketchpads. Have as many pairs of sketchpad and sampler as you have separate instruction and you're set.

Does that make sense?
