= Ensemble Coding =
Ensemble coding, also known as ensemble perception or summary representation, is the ability to see the average or variance of a group of objects. It is a theory that suggests that people process the general gist of their complex visual surroundings by grouping objects together based on shared properties. It has been demonstrated that individuals have the ability quickly and accurately encode ensembles and gather summary statistical information (like the mean and variance) from groups of stimuli. <ref>{{Cite journal|last=Alt|first=Nicholas P.|last2=Goodale|first2=Brianna|last3=Lick|first3=David J.|last4=Johnson|first4=Kerri L.|date=2019-03|title=Threat in the Company of Men: Ensemble Perception and Threat Evaluations of Groups Varying in Sex Ratio|url=http://journals.sagepub.com/doi/10.1177/1948550617731498|journal=Social Psychological and Personality Science|language=en|volume=10|issue=2|pages=152–159|doi=10.1177/1948550617731498|issn=1948-5506}}</ref> <ref>{{Cite journal|last=Alvarez|first=George|date=2011-03|title=Representing Multiple Objects as an Ensemble Enhances Visual Cognition|url=https://dash.harvard.edu/handle/1/41364280|journal=Trends in Cognitive Sciences|language=en-US|doi=10.1016/j.tics.2011.01.003|issn=1364-6613}}</ref> The world is filled with redundant information of which our visual systems have become particularly sensitive to. <ref name=":0" /
