PS260 Lecture Notes - Inattentional Blindness, Change Blindness, Visual Cortex
Document Summary
In addition to these physical sound properties of sound, if the content of the unattended channel is important (e. g. , your name) you will have a cocktail party effect . Inattentional blindness: the failure to see a prominent stimulus, even if one is staring right at it. This effect also emerges with other senses such as hearing (inattentional deafness) and touch (inattentional numbness). Change blindness: the inability to detect changes in a scene despite looking at it directly. Similar patterns of change blindness have been demonstrated in videos or movies and live events. Early selection hypothesis: only attended input is analyzed and perceived. Late selection hypothesis: all inputs are analyzed, selection occurs after analysis; selection may occur before consciousness or later. Selection of information to be attended to may be consequence of priming that is based on your expectations. Spatial attention: your ability to focus attention on a specific location in space.
