Scoping reviews, a type of knowledge synthesis, follow systematic approach to map evidence on topic and identify main concepts, theories, sources, gaps. Although more scoping reviews are being done, their methodological reporting quality need improvement. This document presents the PRISMA-ScR (Preferred Reporting Items for Systematic Meta-Analyses extension Reviews) checklist explanation. The was developed by 24-member expert panel 2 research leads following published guidance from EQUATOR...
This report presents the Consolidated Standards of Reporting Trials (CONSORT) extension for stepped wedge cluster randomised trial (SW-CRT). The SW-CRT involves randomisation clusters to different sequences that dictate order (or timing) at which each will switch intervention condition. statement was developed allow unique characteristics this increasingly used study design. guideline using a Delphi survey and consensus meeting; is informed by CONSORT statements individual trials. items...
Sharing data and code are important components of reproducible research. Data sharing in research is widely discussed the literature; however, there no well-established evidence-based incentives that reward sharing, nor randomized studies demonstrate effectiveness policies at increasing sharing. A simple incentive, such as an Open Badge, might provide change needed to increase health medical This study was a parallel group controlled trial (protocol registration: doi:10.17605/OSF.IO/PXWZQ )...

Perceptual continuity is an important aspect of our experience the visual world. In this study, we focus on example perceptual involving maintenance figure-ground segregation despite removal binding cues that initiated segregation. Fragmented line drawings objects were superimposed a background randomly oriented lines. Global forms could be discriminated from based differences in motion or color/brightness. Furthermore, perception global form persisted after cue had been removed. A...

The peer review process is used throughout science but has often been criticized for being inconsistent, with decisions dependent on the peers who did reviewing. Much of decision inconsistency arises from differences between reviewers in terms their expertise, training and experience. Another source uncertainty within as they must make a single recommendation (e.g. 'Accept'), when may have wavered two 'Accept' or 'Reject'). We estimated size within-reviewer using post-review surveys at three...
Face inversion produces a detrimental effect on face recognition. The extent to which the of faces and other kinds objects influences perceptual binding visual information into global forms is not known. We used behavioral method functional MRI (fMRI) measure persistence, type memory that reflects sustained awareness form. found upright persisted longer than inverted versions same images; we observed similar persistence animal stimuli. This was evident in fMRI activity throughout ventral...
Functional MRI (fMRI) studies of the human object recognition system commonly identify object-selective cortical regions by comparing blood oxygen level-dependent (BOLD) responses to objects versus those scrambled objects. Object selectivity distinguishes lateral occipital cortex (LO) from earlier visual areas. Recent suggest that, in addition being selective, LO is retinotopically organized; represents both and location information. Although have been shown depend on location, it not known...
Early visual areas within each hemisphere (V1, V2, V3/VP, V4v) contain distinct representations of the upper and lower quadrants contralateral hemifield. As receptive field size increases, retinotopy in higher-tier becomes progressively less distinct. Using functional magnetic resonance imaging (fMRI) to map fields, we found that an intermediate level area, lateral occipital region (LO), contains retinotopic maps with a bias, but combined representation field. Moreover, used technique fMRI...
An observational study of uncertainty in peer review
We examined the role of temporal synchrony—the simultaneous appearance visual features—in perceptual and neural processes underlying object persistence. When a binding cue (such as color or motion) momentarily exposes an from background similar elements, viewers remain aware for several seconds before it perceptually fades into background, phenomenon known showed that persistence stimulus synchrony, like arising motion color, is associated with activation in lateral occipital (LO) area,...
‘figure’ stimuli When a camouflaged comprised of disconnected line segments moves, it spontaneously segregates from the background [1]. Following motion offset, form percept persists for up to several seconds when remains—if removed, figure decays more abruptly. The persistence is evident in fMRI activity human lateral occipital cortex (LO) [2].
The human visual system uses feedforward and feedback mechanisms to achieve maintain the figure-ground segregation of global form. One way study is measure persistence form, a type short-term perceptual memory. Studies have shown that maintained by for up few seconds following removal binding cues originally led segregation. Previous studies showed persistence-related fMRI activity in lateral occipital cortex, but failed show V1. If were observed V1 it would suggest from high-level areas...

An important aspect of visual processing involves binding the elementary features an object and segregating them from background features. Previous research demonstrated that fragmented line-drawings objects could be discriminated a randomly orientated lines on basis differences in motion. Furthermore, percept persists for second or so after motion has stopped. Functional imaging showed this persistence was reflected brain activation area LO but not MT+ (Ferber et al, 2003). In present study...
