●● attention: limited capacity
Answer: our brains can only process a small amount of information
available to us at any given time
consequences: not everything in our environment can be attended to so
unselected information receives minimal, if any, processing
(inattentional blindness, change blindness)
adaptive significance: limited capacity is not a flaw but an adaptive
feature. it allows our brains to devote resources to processing
information that is most likely to be useful, enhancing our ability to
make decisions + react to our environment efficiently
●● attention: information overload
Answer: in every day life, we are bombarded with sensory information
without attention, processing all this data simultaneously would
overwhelm our cognitive systems
,●● attention: role of attention
Answer: attention acts as a filter, selecting the most relevant pieces of
information for further processing, based our goals, tasks, + interests
●● inattentional blindness
Answer: obvious stimuli are missed
●● change blindness
Answer: we don't notice when key features in our environment change
●● attention: selection
Answer: the process by which attention allows us to focus on certain
stimuli while ignoring others, essentially determining what information
gets processed further
selective attention: an everyday example is focused on a conversation
with a friend in a crowded room, tuning out other voices and noises. this
demonstrates how we can selectively attend to specific sources
information (cocktail party effect)
●● mechanisms behind selective attention
Answer: out brains use both top-down and bottom-up processes to select
information
top-down: driven by current goals + expectations
,bottom-up: driven by the properties of the stimuli themselves, such as
salience or novelty
●● benefits of selective attention
Answer: by focusing our processing resources on a subset of available
information, selective attention enables us to efficiently interact with our
environment, make decisions, and perform tasks without getting
sidetracked by irrelevant information
●● attention: modulation
Answer: modulation refers to how attention not only selects information,
but also enhances the processing of that information, making it more
prominent or accessible in our cognitive system
selected stimuli are not just noticed, their sensory details are enhanced.
for example, attention can make a sound seem louder or a color appear
more vivid, effectively amplifying the sensory input
●● attention: vigilance
Answer: vigilance or sustained attention involved maintaining focus
over extended periods. this is critical in tasks requiring continuous
monitoring (like driving or studying)
, failure to maintain vigilance can lead to missed information or errors,
highlighting the importance of strategies to sustain attention in tasks of
long duration or monotonous nature
factors such as task difficulty, environmental distractions, and individual
differences in attentional capacity can significantly affect our ability to
stay vigilant
●● practical implications of attention modulation/vigilance
Answer: understanding how to enhance vigilance and the modulation of
attention can inform the design of safer work environments, more
engaging educational tools, and strategies for improving individual focus
and productivity
real life example: consider a security guard monitoring surveillance
footage for hours. vigilance ensures critical moments are noticed and
acted upon despite the monotony of the task. attentional modulation
allows the guard to quickly distinguish between normal and suspicious
activities, enhancing the efficiency of the response
●● taxonomy
Answer: a systemic framework for organizing the diverse aspects of
something into coherent categories
dual dimensions: external attention and internal attention
