Differentstimuli activate different mechanisms, thuseliciting different responses. Unfortunately, thisalso means that our information-processingmachinery is prone to certain kinds of errorsbecause natural selection shaped our brains tointerpret the world in an adaptive fashion andnot necessarily in a truthful...
Introduction Our minds evolved as a set of psychological mechanisms, each designed by natural selection to solve a particular adaptive problem. Different stimuli activate different mechanisms, thus eliciting different responses. Unfortunately, this also means that our information-processing machinery is prone...

This rod response is supernormal in amplitude (greater than 1,000 microV, extrapolated), delayed in time course, and insensitive to dim stimuli, ie, the function relating response to light intensity has been drastically altered. The insensitivity to dim stimuli is accompanied by a mild nyc...

The responses of Ca-dependent action potentials to premature stimulation were studied in the isolated canine ventricular muscle. When very premature stimuli were applied, supernormally augmented responses with propagation occurred, while responses with long preceding intervals were small and not conducted....
