Decoding location-specific and location-invariant stages of numerosity processing in subitizing.

ABSTRACT: Extracting the number of objects in perceived scenes is a fundamental cognitive ability. Number processing is proposed to rely on two consecutive stages: an early object location map that captures individuated objects in a location-specific way and a subsequent location-invariant representation that captures numerosity at an abstract level. However, it is unclear whether this framework applies to small numerosities that can be individuated at once ("subitized"). Here, we reanalyzed data from two electroencephalography (EEG) experiments using multivariate pattern decoding to identify location-specific and location-invariant stages of numerosity processing in the subitizing range. In these experiments, one to three targets were presented in the left or right hemifield, which allowed for deco
