comment 'Model-free' learning in humans
Are you using google? Google scholar search for "model free reinforcement learning" brings up, as the first hit - before anything else - a cognitive neuroscience study with over 103 citations. There is indeed a developing literature on this topic, and the appropriate term is indeed "model free."

comment Are intelligence scores correlated with detection of second stimulus in an Attentional Blink test?
It looks like AB correlates with working memory capacity above and beyond its relationship to fluid intelligence (as measured by Raven's). springerlink.com/content/t221545168371136

comment Are there shapes defined by 3 (or more) generative parameters whose mapping to psychological similarity space is known?
Thanks! Yes, I'll eventually be running a fairly complex design, with all the "normal" features varying. I think I've found a solution though - a good bit is known about the perceptual space of fourier descriptors - a way to characterize shapes. I've just now finished designing an experiment to determine the mapping from subjective to objective space with fourier descriptors. I will update people if this works!

I agree that color is probably the space I will need to consider. Thank you! But I am actually wondering about shape parameters in particular.

I forgot about the monitoring cost for the delayed intention...
