Attention and its effects on stimulus processing - Neural effects of attention on stimulus processing: visual spatial attention

4 important questions on Attention and its effects on stimulus processing - Neural effects of attention on stimulus processing: visual spatial attention

What is the spatial pardadigms

Studies concentrate a lot of spatial, reflecting the fact that vision is seen as particularly spatial in nature

What is a reentrant process

Related activity returns to the same low-level sensory areas that were initially activated in the ascending pass through the system, presumably reflecting enhanced late processing of the stimulus information in those areas

What is the phase-amplitude coupling

The amplitude of higher-frequency oscillations varies with the phase of lower-frequency oscillations gamma-band waves that occur only during the peaks of ongoing lower-frequency oscillations, rather that at other phases of the lower-frequency waves

What is the key finding that show the difference of easy ventral vision task and difficult tasks in the M+ area

By task irrelevant peripheral moving stimuli.
easy task (perceptual load) more processing capacity was available for stimuli in unattended location (more processing of unattended location). Which wasn't the case in difficult tasks

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
