With a rat in a Skinner box, for instance, it will no longer be sufficient to ask why the rat’s bar-presses become more or less frequent; we also have to ask how the rat succeeds in pressing the bar when it may have to start toward it from different places in the box. In other words, how is it that the rat – or ourselves, for that matter – ever manage to hit a target or attain a goal? The answer suggested by the feedback model is that “targets” or “goals” are simply reference signals, i.e. specific values of sensory signals (or constellations of such signals) in the form of an internal representation to which actual sensory signals can be compared. If the comparison shows a discrepancy, an error signal is generated and triggers an activity which modifies the actual sensory signal until it no longer shows a discrepancy from the reference value. The feedback model, moreover, accounts also for a somewhat different situation that stimulus- response theory finds difficult to explain: there can be a “response” (i.e. activity) without a stimulus. Activity is triggered by an error signal, and an error signal is generated not only when there is a change in the sensory signal but also when there is a change in the reference value.","highlights":Ӷ^"jQuery3210139467198483622":^°°Ӻ,"text":"","order":"mw-content-text","category":"Argumentation2","data_creacio":1580315373090°
