CHANGE BLINDNESS

By definition, change blindness is a surprising perceptual phenomenon that occurs when a change in a visual stimulus is introduced and the observer does not notice it.

Change Blindness relates to a person's awareness, or the mind's perception of multiple activities occurring around its environment.

EXAMPLE

OUR EXPERIMENT

• Our experiment was similar, but we used a different method of distraction
• We wanted to conduct this experiment to see :
• How well an individual's mind perceives a confusing situation
• How long it takes an individual to react to change
• If the reaction occurs faster with known people

RESULTS

• We had four participants:
• Two out of the four realized a change had occured, one knew us, the other took longer
• The other two had no idea a change had occured until we told them so (very confused)
• Conclusion: Every human has their own personal awareness factor
• The realization of change is higher for people who know the experimenter
