Creating a new option for online-only research articles: PNAS Plus [Editorial]

Great news for our paperless future: Starting January 2011, PNAS will encourage researchers to publish only online without the article ever making it to the print version. The encouragement will consist of allowing more pages (up to 10; it's 6 now) and free color figures. This will be called PNAS Plus, while the original PNAS seems to be shifting to broader audiences, as PNAS Plus authors will have to contribute 1-2 page broad-audience-readable summaries of their work to (the print version of) PNAS.

The perceptual salience of symmetrical and asymmetrical sections of a line

Subject: The perceptual salience of symmetrical and asymmetrical sections of a line

 

A vertical line segment intersecting a horizontal one at different crossing points generates line sections. Visual perception of such line sections was investigated here in two experiments. In both experiments participants were most accurate and precise when they had to reproduce symmetrical sections. Interestingly, the different asymmetrical sections of a line were not equivalent in terms of participants' performance: constant errors changed as a function of sections and the error curve was nicely interpolated by the composition of two harmonics of the line length. In consistence with the harmonic fitting of the data, we propose that the perceptual salience of specific asymmetrical sections is a byproduct of the automatic triggering of a line midpoint identification process. Being perceptually tuned to symmetry warps our visual representation of the line, which results in systematic misperceptions. The way of bringing present and past experimental findings into a unitary whole is proposed.
