Whilst the processing of visual information proceeds in a forward hierarchy, advancing from simple representations in primary visual cortex to the coding of more complex object-level representations further down the dorsal pathway, it has been proposed that this automatic and implicit processing is accessed by conscious and deliberate cognition in a reverse hierarchy (Hochstein and Ahissar, 2002). Evidence for this theory is largely drawn from studies of attention, for example, in visual search, where features ‘pop-out’, whilst conjunction searches take longer. Given that metacognition is also proposed to rely on explicit vision, the evidence available to metacognitive scrutiny should also proceed in a reverse hierarchy, with higher-level visual representations being more immediately available for metacognitive decisions than lower-level visual representations. Thus, performance in metacognitive tasks on high-level visual decisions should be superior to those on low-level visual decisions. Here we seek to test this hypothesis by directly comparing metacognitive performance on high- and low- level visual decisions within observers. This experiment extends the initial version using online data collection to obtain sufficient trials to adequately compare the ‘boost’ in confidence evidence across the high- and low-level tasks.
