The strategies of middle or upper class native parents could help reveal the covert mechanisms of tracking in the Netherlands.
This highlights the need for a broader theoretical framework incorporating inattentional blindness and overt and covert attention mechanisms.
Using our method, we can better test whether ads and menus are normally available at a glance when fixating the center of a web page, instead of testing how well observers can deploy overt or covert attentional mechanisms.
The most important claim of all commentaries in this issue is that the proposed ideas can all be empirically tested and thereby contribute to the advancement of an unified theoretical framework incorporating IB, AM in consideration of overt and covert attention mechanisms.
Kuhn and colleagues described a novel attentional misdirection approach (deliberate diversion of attention away from a visually salient stimulus) to investigate overt and covert attention mechanisms in connection with inattentional blindness (not being able to perceive something that is plainly visible because one's attention has not been focused on it).
However, inferences based on performance data only may have limited validity, because differences in covert brain mechanisms may lead to similar overt performance [ 21, 27].
However, by analogy to other medically important trypanosome species, the presence of alternate, covert sexual mechanisms within the same species is not entirely unexpected (Rougeron et al., 2009, Rougeron et al., 2011, Duffy et al., 2013, Hickman et al., 2013, Rogers et al., 2014, Ramírez and Llewellyn, 2014).
Beyond that, in places where slaves were imported, carnival has been a covert survival and transmission mechanism for old, African-derived rhythms.
But the idea of an experience-dependent toggling between basal and facilitated states is ultimately consistent with either a persistent priming mechanism or covert memory.
This third mechanism of covert sex can readily maintain a high genotypic diversity in asexual populations without gene flow from sexuals, thereby allowing the buildup of genetic differentiation between the two groups, consistent with our observations and previously reported patterns [ 8].
