The second stage reflects a kind of "ignition," and is achieved only for stimuli that are consciously perceived.
What is consciously perceived is not a simple mapping of the images that fall on the retina.
As expected, the players squeezed harder when the image of a British pound flashed by than when the image of a penny did — regardless of whether they consciously perceived the pictures, many of which flew by subliminally.

Repeatedly, a higher level of political interest was noticed by family members and friends in Poland rather than consciously perceived by the migrant in question.
If a mental state is stable with respect to perturbations, it "activates" a mental representation encoding a content that is consciously perceived.
Next we applied these stimulus parameters in an fMRI experiment to determine whether non-consciously perceived (covert) facial expressions of fear and disgust show the same double dissociation (amygdala response to fear, insula to disgust) observed with consciously perceived (overt) stimuli.
Cognition, 79, 1 37.] proposes that it is impossible for an unconscious stimulus to be used strategically to enhance task performance (bottom up effect), while a fully consciously perceived stimulus can be used to improve task performance (top down effect).
those that are never looked at are less likely to be consciously perceived, hence more likely to remain undetected; i.e. the change was not perceived (e.g. Rensink et al., 1997; Simons & Ambinder, 2005).
Although speech gesture cooperation was not consciously perceived, it proved to influence users' recall performance and subjective evaluations: redundancy increased verbal information recall, ratings of the quality of explanation, and expressiveness of agents.
