The distinction between a preattentive and an attentive processing stage also features in related theories of visual perception (Neisser, 1967).
Previous research showed that the conjunction of homogenous basic features (e.g., color-color conjunction, two different colors with relative spatial relation between them) within an object can only be resolved by focal attentive processing [68].
This hypothesis would be in line with an entrainment theory where synchronization of internal attending activity with an external event is a prerequisite of attentive processing [ 54].
In their review on emotion and attention, Schupp et al. [16] proposed that sustained attentive processing is reflected by the sustained positive slow waves observed in ERP data in the [300 800] ms time window.
Thus, while base grouping maps onto preattentive processing, incremental grouping maps onto attentive processing, and the spread of an enhanced neuronal activity in the visual cortex corresponds to the spread of object-based attention in psychology (Fig. 4c).
Previous research indicated that the processing of landolt-C's orientation requires focal attentive processing ([62], [63]; see [49] for a review), it is thus a type of detailed information.
Circuit properties include a novel synthesis of feedforward and feedback processing, of digital and analog processing, and of preattentive and attentive processing.
The third statistically relevant PC, PC12, was related to the attentive processing of expressed emotions.
By contrast, pre-attentive processing of synthetic items gave rise to a left-enhanced MMF onset (100 ms), but failed to elicit later lateralization effects.
They interpreted their results in terms of a speech-specific pre-attentive processing deficit in children with dyslexia.
