p059fig02.05 Bowed serial position curve.  This kind of data emphasizes the importance of modelling how our brains give rise to our minds using nonlinear systems of differential equations.<BR>||  Effects of [inter, intra]trial intervals (Hovland 1938).  # of errors vs list position. [w (sec), W (sec)] = (2 6) (4 6) (2 126) (4 126).  Nonoccurance of future items reduces the number of errors in response to past items.  Thes data require a real-time theory for their explanation! that is, DIFFERENTIAL equations.
