The human visual system is highly proficient in extracting bilateral symmetry from visual
input. This paper reviews empirical and theoretical work on human symmetry perception …

This review of symmetry perception has six parts. Psychophysical studies have investigated
symmetry perception for over 100 years (part 1). Neuroscientific studies on symmetry …

The way the cognitive system scans the visual environment for relevant information–visual
search in short–has been a long-standing central topic in vision science. From its inception …

We propose that similarity is determined by the transformation distance between
representations: entities which are perceived to be similar have representations which are …

The goal of our study is a better understanding of the role of vertical mirror symmetry in
perceptual grouping. With a simple psychophysical task and a set of controlled stimuli, we …

Symmetry and beauty are strongly linked, but is the positive response to visual symmetry
automatic? We used the Implicit Association Test (IAT) to measure the valence of visual …

This study examined the influence of sex, social dominance, and context on motion-tracked
head movements during dyadic conversations. Windowed cross-correlation analyses found …

The perception and appreciation of visual symmetry have been studied in several recent
EEG experiments. Although symmetry is known to be an important determinant of aesthetic …

In this study, a large number of observers (N= 201) were asked to segment a collection of
outlines derived from line drawings of everyday objects (N= 88). This data set was then used …

Gestalt phenomena are often so powerful that mere demonstrations can confirm their
existence, but Gestalts have proven hard to define and measure. Here we outline a theory of …
