3/3

Attention

• Early v late selection (attentional bottleneck)

  • Early selection => filtering occurs at the sensory level 

  • Late selection => filtering occurs at the cognitive/cortical level

• Method for measuring brain activity during task => measures what (temporal or spatial resolution?)

  • EEG = method

  • measures temporal resolution

• Failure to consciously perceive unattended stimuli is called what?

  • Inattentional blindness

• Symbolic cueing tasks test what? And what do the results indicate? Would responding to invalid or valid cues have an increased reaction time?

  • Tests …

  • Voluntary attention (endogenous)

  • Results: valid = decreased reaction time, invalid = increased

• A search based on two or more features that together distinguish the target?

  • Conjunction search

• Which brain region of the subcortical system is responsible for stimuli filtering?

  • Pulvinar 

• Which brain region is responsible for voluntary attention (human)? (dorsal frontoparietal network)

  • Lateral intraparietal area (LIP; monkey) or intraparietal sulcus (IPS; human)

• Name of system that guides voluntary attention?

  • Dorsal frontoparietal network

• ADHD brain reduction or enlargement? Which brain region does it affect

  • Reduction 

  • Gray and white matter overall, cerebellum volume, frontal lobes
