notes

  • Sequence is a handler for the definition of Ibex’s shuffleSequence variable. As such, its arguments follow the same format as those of Ibex’s seq function. See Ibex’s documentation manual, section called Shuffle sequences.

example(s)


$Sequence( "hello" , randomize("world") )
@
@newTrial( "world" ,
@    newButton("world", "Earth")
@        .print()
@        .wait()
@)
@newTrial( "world" ,
@    newButton("world", "Moon")
@        .print()
@        .wait()
@)
@newTrial( "world" ,
@    newButton("world", "Mars")
@        .print()
@        .wait()
@)
@
@newTrial( "hello" ,
@    newButton("world", "Hello...")
@        .print()
@        .wait()
@)
  • Will run the trial labeled hello first, even though it is defined below the world ones, and then will run all three trials labeled world in a random order.
