Items that stand out from their surroundings, that is, those that attract attention, are considered to be salient. Salience is generated by input features in many stimulus dimensions, like motion (M), color (C), orientation (O), and others. We focus on bottom-up salience generated by contrast between the feature properties of an item and its surroundings. We compare the singleton search reaction times (RTs) of items that differ from their surroundings in more than one feature (e.g., C + O… 

Figures and Topics from this paper

Characterizing the effects of feature salience and top-down attention in the early visual system.
TLDR
The findings indicate that top-down effects of spatial attention can influence visual processing at the earliest possible site along the visual pathway, including the LGN, whereas the processing of orientation- and motion-driven salience primarily involves feature-selective interactions that take place in early cortical visual areas.
Properties of V1 Neurons Tuned to Conjunctions of Visual Features: Application of the V1 Saliency Hypothesis to Visual Search behavior
TLDR
An optimization problem is formulated to investigate neural properties in the primary visual cortex (V1) from human reaction times (RTs) in visual search to find a target bar unique in color, orientation, motion direction, or redundantly in combinations of these features among uniform background bars.
Visual Salience Affects Performance in a Working Memory Task
TLDR
The findings show that the influence of bottom-up attention extends beyond oculomotor behavior to include the encoding of information into memory, as quantified using a previously published computational model.
Fast and Conspicuous? Quantifying Salience With the Theory of Visual Attention
TLDR
Bundesen’s Theory of Visual Attention (TVA) is proposed as a theoretical basis for measuring salience and an empirical and modeling approach to link this theory to data retrieved from temporal-order judgments is introduced.
Preview of partial stimulus information in search prioritizes features and conjunctions, not locations
TLDR
The results indicate that search for, and prioritization of, combinations involve conjunctively tuned neural mechanisms that probably reside at the level of the primary visual cortex.
Change Detection is Easier at Texture Border Bars When They are Parallel to the Border: Evidence for V1 Mechanisms of Bottom-up Salience
TLDR
It is shown that colour changes in texture bars are more detectable when the bars are parallel to the texture border, and this finding supports V1 mechanisms for bottom—up salience.
Neural activities in V1 create the bottom-up saliency map of natural scenes
TLDR
It is suggested that the bottom-up saliency map of natural scenes could be created in V1, providing further evidence for the V1 saliency theory.
Saliency Changes Appearance
TLDR
It is suggested that signals from a master saliency map flow back into individual feature maps and boost the perceived feature contrast of salient objects, even on perceptual dimensions different from the one that initially defined saliency.
Salience from the decision perspective: You know where it is before you know it is there.
TLDR
A model of detection and localization tasks based on random walk processes is proposed, which can account for the present findings and is at variance with two classes of standard models of visual search and object recognition.
Neural Activities in V1 Create a Bottom-Up Saliency Map
TLDR
These findings strongly support the proposal that a bottom-up saliency map is created in V1, challenging the dominant view that the salency map is generated in the parietal cortex.

Salience from feature contrast: additivity across dimensions
TLDR
Test targets that displayed orientation, motion, luminance, or color contrast, or pairwise combinations of these, were presented in line texture arrays, and their saliences were quantified in comparison to reference targets at defined luminance levels, indicating a higher degree of independence between the underlying saliency mechanisms than for other stimulus dimensions.

TLDR
The authors found that a nonsingleton distractor that possesses the target feature produces attentional capture and resistance to capture by irrelevant singletons is mediated by inhibitory processes, arguing against the notion that effects of bottom-up salience and top-down factors on attentional priority are strictly encapsulated within distinct search modes.
Psychophysical Tests of the Hypothesis of a Bottom-Up Saliency Map in Primary Visual Cortex
TLDR
The prediction that most clearly distinguishes the V1 saliency hypothesis from other models is that task-irrelevant features could interfere in visual search or segmentation tasks which rely significantly on bottom-up saliency.

TLDR
The findings demonstrate the efficacy of top-down information in guiding attention and show that it can be applied flexibly, weighted toward particular target features.

TLDR
Together, these experiments show that bottom-up factors have more influence in guiding conjunction searches than previously thought.
The Primary Visual Cortex Creates a Bottom-up Saliency Map
TLDR
It has been proposed that the primary visual cortex (V1) creates a saliency map using autonomous intra-cortical mechanisms, and the model accounted for behavioral data such as how task difficulties can be influenced by image features and their spatial configurations.
The primary visual cortex creates a bottom-up saliency map
TLDR
This proposal links physiology with psychophysics, thereby making testable predictions some of which are subsequently conrmed experimentally and accounted for behavioral data such as how task diculties can be inuenced by image features and their spatial congurations.
The role of features in preattentive vision: Comparison of orientation, motion and color cues
TLDR
Arrays of lines or blobs were used to investigate the role of features vs feature contrast in preattentive vision and, in these dimensions, stimulus coherence is not essential for the discrimination of figure and ground.
A feature-integration theory of attention
TLDR
A new hypothesis about the role of focused attention is proposed, which offers a new set of criteria for distinguishing separable from integral features and a new rationale for predicting which tasks will show attention limits and which will not.
Modeling the role of salience in the allocation of overt visual attention
