Michael, thank you so much for the quick and concise response. A friend of mine referred me to the Discourse page because he was raving about the quick and helpful responses. I really appreciate the help. I hope a few follow up questions are ok before I try to implement your solutions.
- The critical measure of this paradigm is collecting the looking time at each slide after the button press. Since this has only been done in one direction, forward, a single time is collected for each slide. If participants are allowed to move forward and back, will a time be collected in the same way?
i.e. if a participant moves through the slides; 1, 2, 3, 4, 3, 2, 3, 4, 5; will we get a looking time for each of those 9 instances separately? (I’m hoping so.)
- I should also point out that our slideshows can contain 100 images or more. Is this an issue?
-Last, I have an interesting idea which no one has implemented yet in these types of studies. Perhaps you can give me an idea of whether or not this is feasible to implement in PsychoPy. Instead of using a button press to advance (or revisit) each slide discretely. I would like to allow participants to “throttle” through the slideshow in a more continuous way. I imagine a simple knob, joystick, or less exciting a button press which allows participants to roll through the slides in succession (maybe even forward & backward) and instead of collecting a looking time for each slide, we capture the speed at which the participant advances the slides across time.
Thank you again for your support, it is sincerely appreciated!
P.S. if you happened to be curious, I am a PhD student at the University of Oregon in Cognitive Neuroscience and Developmental Psychology. I study the visual and sensorimotor systems in the Perception & Action Lab with an interest in how contextual information guides our actions, and also design research experiments probing the developmental process of statistical learning of action streams in the Acquiring Minds Lab. My work is directed toward practical applications for those with Traumatic Brain Injury, Autism Spectrum Disorders, and Sensory Sensitivity challenges.
