Our visual system organizes spatially distinct areas with similar features into perceptual groups. To better understand the underlying mechanism of grouping, one route is to study its capacity and temporal progression. Intuitively, that capacity seems unlimited, and the temporal progression feels immediate. In contrast, here we show that in a visual search task that requires similarity grouping, search performance is consistent with serial processing of those groups. This was true across… Expand

Figures from this paper

Similarity Grouping as Feature-Based Selection
TLDR
A novel measure is tested with a novel measure—a grouping illusion within number-estimation tasks that should work only if participants simultaneously construct groups—and found the strongest evidence yet in favor of serial feature-based attention. Expand
Spatial alignment facilitates visual comparison.
TLDR
A new principle of spatial alignment is suggested, whereby visual comparison is substantially more efficient when visuals are placed perpendicular to their structural axes, such that the matching components of the visuals are in direct alignment. Expand
Unit of visual working memory: A Boolean map provides a better account than an object does.

TLDR
It is argued that the unit of visual working memory is better defined by the concept of a "Boolean map," which emphasizes the critical role of spatial structure and has been used to characterize the conscious access in attentional processing. Expand
Rethinking the Ranks of Visual Channels
TLDR
The results point to the need for a body of empirical studies that move beyond two-value ratio judgments as a baseline for reliably ranking the quality of a visual channel, including testing new tasks, timescales (immediate computation, or later comparison), and the number of values (from a handful, to thousands). Expand
Jurassic Mark: Inattentional Blindness for a Datasaurus Reveals that Visualizations are Explored, not Seen
TLDR
A task where participants made judgments from one class of marks on a scatterplot was designed, presumably incentivizing them to relatively ignore other classes of marks, revealing that data visualizations are not “seen” in a single glance, and instead require an active process of exploration. Expand
An Evaluation of Semantically Grouped Word Cloud Designs
TLDR
The results of a series of controlled experiments show that layouts in which words are arranged into semantically and visually distinct zones are more effective for understanding the underlying topics than standard word cloud layouts. Expand
Perceived Lighting Uniformity on Pedestrian Roads: From an Architectural Perspective
TLDR
This study suggests that the visual experience of road lighting uniformity for pedestrians is difficult to estimate with photometric values because the visual impact of uniformity is highly influenced by the spatial context and landscape. Expand

Similarity Grouping as Feature-Based Selection

Common-Fate Grouping as Feature Selection
TLDR
This account proposes that a primary mechanism for grouping by common fate is attentional selection of a direction of motion, and predicts that the visual system must be limited to forming only a single common-fate group at a time and that attempts to find a particular common-Fate group among other groups, or among nongroups, should therefore be highly inefficient.

Grouping by similarity is mediated by feature selection: evidence from the failure of cue combination

TLDR
Although low-level grouping cues do indeed work together to determine the perceptual structure preattentively, grouping by similarity is likely mediated by the attentional selection of a feature. Expand
Perceptual grouping and attention: Not all groupings are equal
TLDR
Grouping under inattention is examined using Driver, Davis, Russell, Turatto, & Freeman’s (2001) method to suggest that grouping is a multiplicity of processes that vary in their attentional demands. Expand
New indirect measures of “inattentive” visual grouping in a change-detection task
TLDR
Changes in background grouping remote from the target and to those occurring across an intervening saccade suggest that visual grouping may arise implicitly under inattention and provides a new method for testing the boundaries of this processing. Expand
Flexible visual processing of spatial relationships
TLDR
It is demonstrated that shifts of selection do occur during spatial relationship judgments that feel simultaneous, by tracking selection with an electrophysiological correlate, and it is speculated that static structure across space may be encoded as a dynamic sequence across time. Expand
Perception without attention: Evidence of grouping under conditions of inattention.
Many theories of visual perception assume that before attention is allocated within a scene, visual information is parsed according to the Gestalt principles of organization. This assumption has beenExpand
Visual search and stimulus similarity.
TLDR
A new theory of search and visual attention is presented, which accounts for harmful effects of nontargets resembling any possible target, the importance of local nontarget grouping, and many other findings. Expand
Redundant Encoding Strengthens Segmentation and Grouping in Visual Displays of Data
TLDR
It is shown that this practice can indeed yield a large benefit for rapidly segmenting objects within a dense display, and strengthening visual grouping of display elements, and implications for models of attentional control are discussed. Expand
Traditional and new principles of perceptual grouping
Perceptual grouping refers to the process of determining which regions and parts of the visual scene belong together as parts of higher order perceptual units such as objects or patterns. In theExpand
