“…In particular, the findings underscore that the goal of attention is to ensure we act upon the right object at any given moment, and that capacity limits in attention reflect physical constraints imposed by the number of actions that can be performed coherently on an object at a time (Humphreys et al, 2013). Whether real objects trigger a greater number of competing action plans than images, or whether these plans and their associated feedback gains are stronger, more highly elaborated (Gallivan, Logan, Wolpert, & Flanagan, 2016), or temporally distinct, awaits further investigation. Our data from adults align with studies showing that children habituate differently (Gerhard, Culham, & Schwarzer, 2016) and maintain fixation longer (Mustafar, De Luna, & Rainer, 2015) upon real objects versus matched 2D images, and add to an emerging literature showing that cognitive processes such as object recognition (Chainay & Humphreys, 2001; Humphrey et al, 1994), memory (Snow et al, 2014) and decision-making (Bushong et al, 2010; Mischel & Moore, 1973), as well as neural responses (Snow et al, 2014), differ between real objects versus 2D images.…”
