Hi, I’m trying to write a sound experiment and i need to randomize some events.
Stimulus list
8 long sounds (20")
28 couples of short sounds (AB - 3" each one)
4 reverse couples of short sounds (BA - 3" each one)
4 same sounds (AA/BB - 3" each one)
I want to script the experiment as it must show 2 random long sounds, let the subject evaluate them with 3 semantic differentials answers, then show 9 couples (randomizing AB, BA, AA/BB), letting them evaluate every couple for preference, then presenting other 2 long sound evaluation and so on. Can you help me?
Exp flow
- long sound 1
sem_diff_1
sem_diff_2
sem_diff_3 - long sound 2
sem_diff_1
sem_diff_2
sem_diff_3 - couple sound 1
preference - couple sound 2
preference - couple sound 3
preference - couple sound 4
preference - couple sound 5
preference - couple sound 6
preference - couple sound 7
preference - couple sound 8
preference - couple sound 9
preference - long sound 3
sem_diff_1
sem_diff_2
sem_diff_3 - long sound 4
sem_diff_1
sem_diff_2
sem_diff_3
and so on… Thanks all!
