What are the building blocks of our visual representations? Whatever we look at, the things
we see will have some feature variability: even snow is not purely white but has a range of …

This Element outlines the recent understanding of ensemble representations in perception
in a holistic way aimed to engage the general audience, novel and expert alike. The …

Ensemble representations have been considered as one of the strategies that the visual
system adopts to cope with its limited capacity. Thus, they include various statistical …

We recently demonstrated that observers are capable of encoding not only summary
statistics, such as mean and variance of stimulus ensembles, but also the shape of the …

Ongoing discussions on perceptual averaging have the implicit assumption that individual
representations are reduced into a single prototypical representation. However, some …

Broadly defined, visual search is the act of looking for something or a number of things. It is
reasonable, at the start of a survey of the topic, to ask why we have to search at all. Part of …

Ensemble representations are often described as efficient tools when summarizing features
of multiple similar objects as a group. However, it can sometimes be more useful not to …

Recent evidence suggests that observers can grasp patterns of feature variations in the
environment with surprising efficiency. During visual search tasks where all distractors are …

Observers can learn complex statistical properties of visual ensembles, such as their
probability distributions. Even though ensemble encoding is considered critical for …

Recently, Wang, Buetti and Lleras developed an equation to predict search performance in
heterogeneous visual search scenes (ie, multiple types of non-target objects simultaneously …
