Process the meaing of distracting info open to distraction and will process task-irrelelvant info - Demanding tasks: Attention acts as predicted by early filter models Process only perceptual features of distracting info aren’t distracted by other info bc our processes are ‘used up’ fully loaded! Support: Lavie et al - Search for names in the list and indicate if it is a entertainer or political figure - Flanking the list are faces that are: Congruent (the same as the searched name) Incongruent (different than the searched name) people are processing the unattented faces: influences how they perform on the task A study by Neisser and Becklen used a visual analogue of dichotic listening called selective looking (occurs when we are exposed to two events simultaneously, but attend to only one of them). Attention Capture and Inattentional Blindness Inattentional blindness - Failure to attend to events that we expect to notice - “looking without seeing” - Ex: when you roll over deer in car say it just jumped at last moment, but actually was here all along - the object/event must be fully-visible (it can be seen) - the inability to notice the object/event is because of attention and not because of visual features of the input - the object/event is unexcepted (the effect is not due to being distracted or engaging attention) - Inattentional VS change blindness - Change blindness: a failure to detect change in a display (attention and memory) - Inattentional blindness: a failure to see somthing in a display that is right there (attention and perception) Marc and Rock: an inattentional blindness task - two main features of this task
participants aren’t expecting a target but are looking in the general area participants are using attention ressources for some task - over many trials: people are presented cross on screen, which arm of cross is longer? - A small black square is introduced Result: people don’t notice the small square evidence for inability to perceive unexpected info same experiement, but put ‘armpit’ instead of black square - then ask person to complete word stem ARM___ people more likely to fill in ARMpit more than any other word - people are registering info taht they are inatentionally blind to at some level Backward masking task: name the color patch color matches that matched (congruent) a masked target words (unaware) were more quickly named (primed) than color patches that didn’t match (incongruent) the target word- inatention isn’t only due to forgetting Déjà vu: - impression of having experienced a situation but the situation is new - 2/3 people report at least 1 deja vu - more common in: people with higher education, people who are more travelled (bc new palces), with age + can be associated with brain injury (epilepsy) explained by inattentional blindness and effect of implicit priming - you will experience a new setting but won’t be aware - however, info you’re accounting will still affect your behavior (implicitly), below threshold -
