Eighty participants completed one of four attentional tests designed to assess sustained attention (SUSTAIN), attentional orienting (ORIENT), divided attention (DIVIDE) or selective attention (SELECT).
However, Lewis does not specify the 'principles of invidious selection' by which some parts of the causal history are selected for attention, except to mention the relevance of Grice's maxims of conversation.
A stimulus may be selected for attention while it is still present in the visual scene (predictive selection) or after it has vanished (post hoc selection).
We present a biologically inspired computational model that accounts for the prioritized processing of information about targets that are selected for attention either predictively or post hoc.
Once a project is selected, all attention is focused on its completion within the stipulated time and cost, without much consideration to either the assumptions made at the time of project selection or the requirements of the implementation phase.
In the course of repairing a shelf, one might use a hammer and feel its heft and balance to be splendidly proportioned for the task, feel the handle to be molded in a way that perfectly fits one's hand, perceive its materials to have been selected with attention to their fitness for driving nails, and so forth.
Note that what biota are considered to be of conservation interest is typically not entirely determined by biology: charismatic species, including those of symbolic social value, such as national birds and animals, are often selected for attention irrespective of the intrinsic biological importance of their conservation.
It is possible however, that factors beyond perceptual grouping play a role in defining the objects selected by attention.
Viewed collectively, these data point to a role of neural substrates involved in the computation of mid-level grouping factors or Gestalt principles in the formation of the objects selected by attention.
Valentine et al. (5) found from general population surveys of 'health system responsiveness' in 41 countries that most respondents selected prompt attention as the most important domain.
