9 good questions on "Attention and its effects on stimulus processing"

Define exogenous attention (also called reflexive attention)
Numerous stimuli arise from events or conditions in our everyday environment attract automatically attention
Report
What is it called when stimuli attract attention from the environment
Involuntary
Report
What are the two perspectives of Neuroscientific approaches to studying attention
  1. Investigating how the neural processing of stimuli are modulated by attention under different circumstances
  2. determining the sets of higher-level control regions of the brain that coordinate this modulation, and the mechanisms by which they do so
Report
What is meant with attentional control
This modulate a stimulus processing are brought about and coordinated in the brain and to examine the idea that specific set of brain regions might work together as part of an overarching attentional control system
Report
Explain the mismatch negativity (MMN)
Deviant auditory stimuli is a stream of otherwise identical sounds produce a negative wave peaking at about 150 t0 200 ms after the deviant stimulus
Report
What is the key brain region for processing the motion of visual stimuli
Area M+ in the lateral occipital lobe
Report
What happens in a shadowing task
You hear two story simultaneously but you have to pay attention to one and not the other
Report
What is the attentional blink
When you see letter and one has a different colour you are less likely to see the letter next to it
Report
Late attention effects might extend back to V1 in some cases and not others why is this
It could be greater need to extract more detailed information for tasks that are more demanding, such as when stimuli are closely spaced.
