visual hindsight bias demo

[Jonathan Mueller]

Ever-resourceful tipsters,   Here's a challenge for you.  I just read an interesting article in the most recent issue of Psychological Science entitled, "We saw it all along: Visual hindsight bias in children and adults."  (It can be found online at http://faculty.washington.edu/gloftus/Downloads/BALM.pdf)   I would like to recreate what they did in class somehow.  Here is the abstract of the article to show you what they did.   "We traced the developmental origins and trajectory of the hindsight bias. Three-, four-, and fiveyear-old children and adults identified gradually clarifying images of degraded common objects on acomputer. Half the time, observers did not know in advance what the object would become. Other times, observers knew in advance the object's identity, and estimated when a na�ve same-age peer would identify the clarifying object. In two experiments, children and adults demonstrated hindsight bias by using advance knowledge to overestimate their same-age peers' ability to identify the objects. The magnitude of this bias declined across age in one experiment, but remained relatively stable over age in the other experiment. These findings may have important implications for children's theory of mind."   I would like to be able to use some animation to produce pictures of objects that gradually become more and more defined.  Do you know of any such animations on the web, for example, that you could point me to that I could use in class?  Or, do you know of a simple way I could create such animation in PowerPoint or some other common program?   Is this clear what I am after?  Any help would be appreciated.  Thanks,   Jon   =============== Jon Mueller Professor of Psychology North Central College 30 N.
