Reply To: Cannot get the template function to loop over my experiment

Hi Xiangyu,

You cannot use a javascript function in that wait command: documentation, source code. Since that’s not supported, you cannot assume that this.keys will return a key that was pressed

Neither Ibex nor PennController define a global JavaScript log function. PennController has newTrial().log and element-specific log commands

If you want to add a column to the rows of this trial that will report whether the pressed key was correct, you can use a global Var element:

newTrial(
  // ...
  newVar("Correct", 0).global(),
  // ...
  newKey("keypress", "FJ")
    .log()
    .wait()
    .test.pressed( variable.CorrectResponse ) // assuming that CorrectResponse in the table is either F or J
    .success( getVar("Correct").set(1) )
  ,
  // ...
)
.log( "CorrectResponse" , getVar("Correct") )
