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.

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.

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.

Visual working memory for connected 3D objects: effects of stimulus complexity, dimensionality and connectivity

Visual working memory (VWM) is typically measured using arrays of two-dimensional isolated stimuli with simple visual identities (e.g., color or shape), and these studies typically find strong

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).

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.

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.

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.

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.

Cortical algorithms for perceptual grouping.

TLDR
This review provides a conceptual framework of how perceptual grouping may be implemented in the visual cortex and two mechanisms are responsible for perceptual grouping: base-grouping and incremental grouping.

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.

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.

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.

Perception without attention: evidence of grouping under conditions of inattention.

TLDR
The results suggest that Gestalt grouping does occur without attention but that the patterns thus formed may not be encoded in memory without attention.

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.

Spacing affects some but not all visual searches: implications for theories of attention and crowding.

TLDR
The observed spacing effect in visual search suggests that for certain tasks, serial search may result from local neuronal competition between target and distractors, soliciting attentional resources; in other cases,serial search must occur for another reason, for example, because an item-by-item, attention-mediated recognition must take place.
