EXTRA TIME AND FOCUS DO NOT HELP TO ACHIEVE A MORE ACCURATE VISUAL PERCEPTION FOR A FEW-SECOND INTERVAL

Abstract

Whether increased attention leads to better perception is a debate that has been going on for decades. The presented experiment investigated this relationship in situations of interest to Consumer Neuroscience: respondents had to evaluate two stimuli in the same visual field containing distractors in a short interval, from two to six seconds. The perceived relative sizes of the two stimuli were self-reported, while data obtained from EEG metrics, eye-tracker, and time were used as measures of attention; all led to positive correlation coefficients with perception error (measured as the difference from the actual ratio of the two sizes), although some were statistically significant while others were not.
