Hal Pashler

The model, partly inspired by early work by Alan Welford,[13] makes many predictions about patterns of behavioral response times in the Psychological Refractory Period experiment.

[15] In 1988, Pashler published the first demonstration of the perceptual phenomenon that later came to be called change blindness, using displays of letters that appeared, disappeared, and reappeared (sometimes with alterations).

The theory argues that a specific type of abstract data structure (the Boolean Map) characterizes the contents of human visual awareness at any given instant in time.

[22] In 2008 (with Edward Vul) Pashler showed that the famous Wisdom of Crowds Effect first noted by Francis Galton could be elicited within a single individual.

[23] This discovery, termed the “Inner Crowd Effect” by The Economist[24] helped prompt follow-up research examining potential new methods of improving human judgment accuracy.

[25] Pashler has also published several articles on varied topics in political psychology, including biases in perception of newsworthiness and attitudes to pro-liberty views.

The paper (published under the milder title "Puzzlingly Large Correlations...")[27] produced an intense controversy that was covered in popular media[7] as well as academic press.
