What is the role of the right frontal lobe in attention?
responsible for sustained attention.
What does the left prefrontal cortex manage in terms of attention?
responsible for attention switching.
Which brain structures are involved in complex attention functions?
Anterior right hemisphere structures (Thalamus, Basal Ganglia) are involved in complex attention functions.
What can result from poor attention?
poor memory.
What are the components of the right hemisphere attention network?
The right hemisphere attention network includes the right frontal lobe, right posterior parietal cortex, prefrontal cortex, and cingulate gyrus.
What is Early Filter Theory?
Early Filter Theory shows that all stimuli come in, irrelevant stimuli are filtered out, and selected stimuli are processed.
How does Late Filter Theory differ from Early Filter Theory?
Late Filter Theory analyzes all stimuli early and selection is based on importance, rather than filtering irrelevant stimuli out.
What is the focus of Selection Models in theories of attention?
Selection Models focus on how we select which stimuli to process from a pool of sensory information.
Describe divided attention
the ability to attend to and process multiple stimuli or tasks simultaneously.
What does the term 'resource allocation theory' refer to?
it refers to how attention resources are allocated to various tasks from a single pool.
What cognitive load impact does the most recent model (Viding, 2004) discuss?
It discusses how the extent to which stimuli are ignored depends on the cognitive load of the selected stimuli.
What is the relationship between attention and working memory?
Attention is closely associated with working memory, as it helps hold onto new information as it is encoded.
What is focused attention?
the ability to concentrate on a specific stimulus.
What leads to distractibility in individuals?
Distractibility can result from challenges in attention allocation and processing multiple stimuli.
What does sustained attention refer to?
the ability to maintain attention over long periods of time.
What effect does stress, illness, or fatigue have on attention?
They can impair attention and lead to difficulties in attending to tasks.
What is the impact of attending to stimuli of the same modality compared to different modalities?
Attending to stimuli of the same modality can cause a reduction in performance.
What is the significance of processing speed in memory encoding?
If processing speed is slow, details can be lost before they are fully encoded into memory.
Describe Selective Attention
Selectively process information while inhibiting competing stimuli
Describe Alternating Attention
involves moving attention from one task or stimulus to another.
What can Attention Impairments cause challenges with?
Attending to external stimuli (i.e., comatose patients)
Decreased reaction time
Reduced speed of information processing
Longer to learn
Difficulty w/ Concentrating, Multi-tasking, Accuracy
Distractibility
Attention is closely associated with what?
Working Memory, Executive Function, Processing Speed
