Open AccessThe role of framing, agency and uncertainty in a focus-divide dilemma
How to prioritise multiple objectives is a common dilemma of daily life. A simple and effective decision rule is to focus resources when the tasks are difficult, and divide when tasks are easy. Nonetheless, in...

Open AccessSix of one, half dozen of the other: Suboptimal prioritizing for equal and unequal alternatives
It is possible to accomplish multiple goals when available resources are abundant, but when the tasks are difficult and resources are limited, it is better to focus on one task and complete it successfully tha...

Open AccessVisual search habits and the spatial structure of scenes
Some spatial layouts may suit our visual search habits better than others. We compared eye movements during search across three spatial configurations. Participants searched for a line segment oriented 45∘ to the...

Open AccessShared attention for action selection and action monitoring in goal-directed reaching
Dual-task studies have shown higher sensitivity for stimuli presented at the targets of upcoming actions. We examined whether attention is directed to action targets for the purpose of action selection, or if ...

Open AccessThe eye that binds: Feature integration is not disrupted by saccadic eye movements
Feature integration theory proposes that visual features, such as shape and color, can only be combined into a unified object when spatial attention is directed to their location in retinotopic maps. Eye movem...

The Relationship Between Spatial Attention and Eye Movements
The nature of the relationship between spatial attention and eye movements has been the subject of intense debate for more than 40 years. Two ideas have dominated this debate. First is the idea that spatial at...

A Generative Model of Cognitive State from Task and Eye Movements
The early eye tracking studies of Yarbus provided descriptive evidence that an observer’s task influences patterns of eye movements, leading to the tantalizing prospect that an observer’s intentions could be i...

Open AccessThe role of attention in eye-movement awareness
People are unable to accurately report on their own eye movements most of the time. Can this be explained as a lack of attention to the objects we fixate? Here, we elicited eye-movement errors using the classi...

The effect of visualization on visual search performance
Striking results recently demonstrated that visualizing search for a target can facilitate visual search for that target on subsequent trials (Reinhart et al. 2015). This visualization benefit was even greater th...

Open AccessLocal form interference in biological motion perception
Replacing the local dots of point-light walkers with complex images leads to significant detriments to performance in biological motion detection and discrimination tasks. This detriment has previously been sh...

Attentional load interferes with target localization across saccades
The retinal positions of objects in the world change with each eye movement, but we seem to have little trouble kee** track of spatial information from one fixation to the next. We examined the role of atte...

Driving forces in free visual search: An ethology
Visual search typically involves sequences of eye movements under the constraints of a specific scene and specific goals. Visual search has been used as an experimental paradigm to study the interplay of scene...

Eye movements, not hypercompatible map**s, are critical for eliminating the cost of task set reconfiguration
Residual switch costs are notoriously difficult to eliminate. Yet Hunt and Klein (2002) eliminated them in a task that required observers to alternate between 8 trials of prosaccades and 8 trials of antisaccad...

Eliminating the cost of task set reconfiguration
With insufficient time to fully prepare for a switch in task, a deterioration in performance on the first trial of a new task would be expected. The interest of researchers has been captured by the residual sw...
