    . Expectation of a stimulus increases response bias, but affective salience increases sensitivity to noise that looks like a conditioned signal -- in the signal's absence. Max Jativa, 3-4pm, poster III9

    My student Lia Kendall has been applying her training in vision science to her love of photography. In this youtube video she reviews a soviet lens and shows some pretty stunning portraits she's taken with it.

    My reinvention of Ed Rolls' 2D wheel. All 4 axis ends are high salience. Current neurosci/modeling work in RL/decision making has focused on value quadrant. Meanwhile affective scientists have been laboring along valence axis. Very different ideas of what "negative" means!

    I believe Panksepp was quite influenced by Rolls. My next mental exercise was going to be precisely to think about how his 4 blue ribbon grade A emotions map onto Rolls' axes. I've always appreciated how Panksepp adds action tendencies into the mix.

    In the Rolls paper he more or less distinguishes a valence (direct punishment to reward) and a value (gain vs. loss of reward) axis, and links the presence or absence of reward vs. punishment to specific emotional responses. I think I buy it. Am curious about objections though.
