Data interpretation self-paced reading experiment

zoe_e

Hi there,

I set up a self-paced reading experiment in OpenSesame, in which participants are presented one word at a time and the next word is presented once the space bar is pressed. Now that I have collected data for the experiment, I am unfortunately a bit unsure how to interpret it.

The data I am looking for is the time between the stimulus onset and the keypress, so the reading time for each individual word.

Is this difference directly logged in the variable "response_time_stimulus"? The data for this variable is very similar to the manually calculated difference between "time_logger " and "time_stimulus", but not identical.

I have attached the experiment, in case you would like to have a look at it. :)

Hi Zoé,

Is this difference directly logged in the variable "response_time_stimulus"?

This variable is the time between the start of the stimulus sketchpad response item, and the button press. So indeed it should essentially be the reading time.

I don't think your implementation is necessarily wrong, but the "normal" way of achieving this, would be to specify the duration of the sketchpad to 0 and include a keyboard item right after it (followed by a logger). Like that you would obtain a variable response_time that would be the reading time, but as far as I see, your variable should be also fine.

Hi Eduard,

thank you very much for your help and the feedback regarding the structure of the experiment! I will keep it in mind for my next implementation.

Cheers,

Zoé :)
