TLDR
The results were that switch costs increased roughly linearly in both conditions, in line with load accounts, and in light of recent proposals that working memory reflects lingering neural activity at various sites that operate on the stimuli in each case and findings showing neurally silent working memory representations.About:

Citation classic - optimal foraging - a selective review of theory and tests
TL;DR: A review of the literature on optimal foraging can be found in this article, with a focus on the theoretical developments and the data that permit tests of the predictions, and the authors conclude that the simple models so far formulated are supported by available data and that they are optimistic about the value both now and in the future.
Journal ArticleDOI
Guidance and selection history in hybrid foraging visual search
TL;DR: The results of these hybrid foraging studies cast new light on the ways in which prior selection history guides subsequent visual search in general.
Journal ArticleDOI
Dynamics of visual attention revealed in foraging tasks.
TL;DR: Foraging tasks provide a remarkably intricate picture of attentional selection, far more detailed than traditional single-target visual search tasks, and well-known theories of visual attention have difficulty accounting for key aspects of the observed foraging patterns.
Journal ArticleDOI
Can you have multiple attentional templates? Large-scale replications of Van Moorselaar, Theeuwes, and Olivers (2014) and Hollingworth and Beck (2016).
TL;DR: The authors showed that memory-driven capture disappears when more than one item was held in VWM, in line with the single-item-template hypothesis, in contrast to the multiple-item template hypothesis.

Humans can efficiently look for but not select multiple visual objects
Eduard Ort,Johannes J. Fahrenfort,Johannes J. Fahrenfort,Tuomas ten Cate,Martin Eimer,Christian N. L. Olivers +5 more
TL;DR: The results revealed only small neural and behavioral costs associated with preparing for selecting two objects, but substantial costs when engaging in selection, and suggest this cost is the consequence of neural competition resulting in limited parallel processing, rather than a serial bottleneck.

A feature-integration theory of attention
Anne Treisman,Garry A. Gelade +1 more
TL;DR: 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.

Neural Mechanisms of Selective Visual Attention
Robert Desimone,John S. Duncan +1 more
TL;DR: The two basic phenomena that define the problem of visual attention can be illustrated in a simple example and selectivity-the ability to filter out un wanted information is illustrated.

The information capacity of the human motor system in controlling the amplitude of movement.
TL;DR: The motor system in the present case is defined as including the visual and proprioceptive feedback loops that permit S to monitor his own activity, and the information capacity of the motor system is specified by its ability to produce consistently one class of movement from among several alternative movement classes.
Journal ArticleDOI
Optimal foraging, the marginal value theorem.
TL;DR: This paper will develop a model for the use of a “patchy habitat” by an optimal predator and depresses the availability of food to itself so that the amount of food gained for time spent in a patch of type i is hi(T), where the function rises to an asymptote.

The capacity of visual working memory for features and conjunctions
Steven J. Luck,Edward K. Vogel +1 more
TL;DR: It is demonstrated that it is possible to retain information about only four colours or orientations in visual working memory at one time, but it is also possible to retaining both the colour and the orientation of four objects, indicating that visual workingMemory stores integrated objects rather than individual features.
