This is fantastic Robert!
I have to admit, when I had initially tried your syllogism app, I was discouraged by the difficulty in learning the interface.
But this study gives me renewed motivation to start using your app.
An average 8.9 increase in IQ points? That is truly significant.
I'm sure there would be caveats, like the age of participants, speed/difficulty of training, etc.
But even still, without full knowledge, worth trying out Relational Operant Training.
I hope future studies shed more light on how to optimize this type of training.
