Measuring attention using flash-lag effect
TL;DR: The results showed that the effect of cueing increased monotonically with the number or the speed of the objects, suggesting that the amount of attention can be estimated by measuring the FLE, assuming that more amount of Attention is required for a larger number or faster speed of objects to attend.

Abstract: We investigated the effect of attention on the flash-lag effect (FLE) in order to determine whether the FLE can be used to estimate the effect of visual attention. The FLE is the effect that a flash aligned with a moving object is perceived to lag the moving object, and several studies have shown that attention reduces its magnitude. We measured the FLE as a function of the number or speed of moving objects. The results showed that the effect of cueing, which we attributed the effect of attention, on the FLE increased monotonically with the number or the speed of the objects. This suggests that the amount of attention can be estimated by measuring the FLE, assuming that more amount of attention is required for a larger number or faster speed of objects to attend. On the basis of this presumption, we attempted to measure the spatial spread of visual attention by FLE measurements. The estimated spatial spreads were similar to those estimated by other experimental methods.

Time courses of attentional modulation in neural amplification and synchronization measured with steady-state visual-evoked potentials
TL;DR: It is demonstrated that attention increased SSVEP phase coherence earlier than it increasedSSVEP amplitude, with a positive correlation between the attentional modulations of SSVEPs phase coherent and amplitude.

The Flash-Lag Effect and Related Mislocalizations: Findings, Properties, and Theories
TL;DR: The flash-lag effect appears to involve low-level perceptual processes and high-level cognitive processes, reflects the operation of multiple mechanisms, occurs in numerous stimulus dimensions, and occurs within and across multiple modalities.

Visual attention spreads broadly but selects information locally
TL;DR: This report provides electroencephalographic and behavioral evidence for the attentional spread at an early stage and selection/inhibition at a later stage of visual processing and proposes a two-stage model of spatial attention with broad spread at a late stage and local selection at aLater stage.
The Flash-Lag, Fröhlich and Related Motion Illusions Are Natural Consequences of Discrete Sampling in the Visual System.
TL;DR: It is shown that the discrete perception hypothesis, with a single free parameter, the perceptual moment or sampling rate, can quantitatively explain all of the scenarios of the Fröhlich and flash-lag effect.

TL;DR: The LC-NA system plays an important role in the facilitation of transient attention driven by voluntary action and is positively correlated with both the peak amplitude of pupil dilation and the pupil size at the time of the key press.

Orienting of attention
TL;DR: This paper explores one aspect of cognition through the use of a simple model task in which human subjects are asked to commit attention to a position in visual space other than fixation by orienting a covert mechanism that seems sufficiently time locked to external events that its trajectory can be traced across the visual field in terms of momentary changes in the efficiency of detecting stimuli.
On data-limited and resource-limited processes
TL;DR: The principles discussed show that conclusions about the interactions among psychological processes must be made with caution, and some existing assumptions may be unwarranted, as well as resulting in some new interpretations of interactions among competing psychological processes.

Tracking multiple independent targets: Evidence for a parallel tracking mechanism*
Zenon W. Pylyshyn,Ron W. Storm +1 more
TL;DR: Two studies are reported which suggest that, while certain aspects of attention require that locations be scanned serially, at least one operation may be carried out in parallel across several independent loci in the visual field, that is the operation of indexing features and tracking their identity.
Visual attention within and around the field of focal attention: A zoom lens model
TL;DR: Two experiments focused upon the following questions: can the spatial extent of the attentional focus be made to vary in response to precues and is there a decrease in processing efficiency for stimuli within the focus?
