Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Attention enables behavior by modulating both sensory inputs and task goals. Combining attentional resources from both of those sources exerts qualitatively large effects on manual performance. Here we tested how combined attention was represented in sensory processing, as reflected by the P1 component and associated activity in the alpha band. We measured performance and recorded EEG while participants’ attention was engaged in an automated, endogenous, and combined (i.e., automated and endogenous) manner. Behavioral results replicated past reports with reliable effects of isolated automated and endogenous attention, as well as their qualitatively unique combined effect. ERP analyses indicated expected increases in P1 amplitude for validly relative to invalidly cued targets in automated and endogenous conditions. However, in the combined case, the P1 difference between validly relative to invalidly cued targets decreased. Analyses of target-locked alpha-band further revealed that this condition was associated with an increased synchrony in the alpha frequency for invalidly cued targets. This suggests that the large performance benefit observed when attentional systems combine is partly driven by suppressed processing of unexpected targets, dovetailing with the notion that in addition to increasing sensory gain of attended targets, attention may also modulate complex behavior by increasing suppression of unattended ones.
