There is accumulating evidence that AD patients have a shallower slope of the learning curve than controls for learning tasks that use repeated items [ 12, 22].
Although the slope of the learning curve across age was smaller for the MCI group, this interaction was not significant.
"It's a Slippery Slope" was about learning to ski.
Memorize these LINE FORMULAS and the SLOPE FORMULA: Learn that the Point-Slope Form for the equation of a Line in the Cartesian Plane is: (y - y1) = m*(x - x1), where {x1), y1)} designates the Cartesian coordinates of a point on the line, {x, y} designates the Cartesian coordinates of a second point on the line, and m = the slope of the line.
1) For the behavioural results, the authors report that the slopes of learning were no different for permanent versus transient landmarks and neither were the final measures of recognition, but do not report whether recognition accuracy differed across the permanent and transient landmarks at time points throughout learning (i.e. when analyzed by quarter, in keeping with the imaging results).
These observations suggest that animals could empirically learn the appropriate slope for different distributions of food, and in this way perform nearly optimal foraging strategies with minimum computational effort.
The neural activity shows a consistent increase in panel A (P = 0.014) and decrease in panel D (P = 0), before the estimated learning trial, as in Figure 2 (see section "Slope of neural change before learning" for Methods).
There was a trend toward a significant difference in terms of learning slopes for PD ON compared to the collapsed control group, F1,45 = 3.90, MSE = 0.00, P = 0.055, reflecting slower learning for PD patients on dopaminergic medication.
BUTTERMILK The gentle slopes of Buttermilk are an ideal place for those learning to ski or ride, but it is not a bunny hill in the classic sense.
We next compared learning slopes for PD patients ON versus OFF medication relative to those of healthy controls.
