Lecture 8- Attention And Cognitive Control Flashcards
Cognitive load increases or reduces distractor processing
Increases
Perceptual load increases or reduces distractor processing
Reduces
Perceptual load increases or reduces inattentional blindness
Increases
Availability of perceptual capacity determines
Whether distractors receive further processing
Cognitive control required to
Inhibit any distractors that make it to late selection
Individuals with low working memory capacity show increased
- Response competition interference
- Stroop interference
- “Own name break-through” in dichotic listening
Are individuals with better cognitive control less distracted?
Yes
Cognitive control deficits also implicated in relation to
Clinical symptoms of inattention (e.g. ADHD, Anxiety)
Patients with damage to which region show problems in attention and cognitive control
Frontal/parietal regions
Attention modulates neural activation related to
Perception
Frontal activation positively or negatively predicted behavioural interference
Negatively
Visual cortical response to cues location is
Effect of attention
People high in anxiety recruited
- Less DLPFC and ACC.
- Greater behavioural interference
What is DLPFC
Dorsolateral prefrontal cortex
What is ACC
Anterior Cingulate Cortex
Frontal regions also activated during
Sustained attention
Mind wandering positively or negatively relates to external task-irrelevant distraction
Positively
Some frontal regions involved in both
- Attentional control.
- Generating task-unrelated thought
High working memory capacity associated with increased or reduced mind-wandering during attentionally demanding tasks
Reduced
High working memory capacity associated with increased or reduced mind-wandering during low perceptual load response competition tasks
Increased
