Document Summary
Learning involves attention, not all information is important for achieving a particular goal. In pursuit of some goal, organisms must overcome initial fascination to salient but irrelevant attributes: four experimental effects which show us that attention is important for learning. In the absence of validity, high salience cues will attract attention. Low salience cues will not attraction attention. Salience is a property readily illustrated by pop-out visual search displays (also, false pop- out: posner cuing task. Learning to pay attention to the cue that has perfect validity (predicts location perfectly) As validity of the low salient cue is increased, utilisation of the low salient cue increases and utilisation of the high salient cue decreases. Attention having limited capacity -> increased utilisation of one cue necessarily decreases the utilisation of the other cue. Utilisation is similar to validity but concerns how much people will learn about or use a cue. Increased validity leads to increased utilisation (and vice versa)
