Perceptual load is the _____________ processing demands presented by a stimulus
immediate
a “shadowing experiment” is when participants must _______ their attention on just one out of two or more simultaneous streams of stimuli
focus
Our “limited selective attention” is also referred to as ______________________. Which is
further described as: shifting around environment, highlighting stimuli for enhanced processing.
attentional spotlight
Easy problem of consciousness is the understanding how particular __________ of neural activity create specific conscious experiences by reading the brain activity directly from people’s brain as they’re having particular _________________.
patterns, experiences
Hard problem of consciousness is understanding the brain ______________ that produce people’s subjective experiences of their conscious perceptions- that is, their qualia
processes
The TPJ is located at the border of the temporal & parietal lobes of the ________ hemisphere.
right
The TPJ is responsible for shifting ___________ to a new location after target onset
attention
Researchers interfered with attention when scanning the IPS by using transcranial ____________ stimulation.
magnetic
1st Symptom of Balint’s Syndrome is known as oculomotor apraxia. This is when a person is having great difficulty steering their ________ gaze appropriately.
visual
2nd Symptom of Balint’s Syndrome is known as optic ataxia. This is when a person is unable to accurately reach for ________ using visual guidance.
objects
3rd Symptom of Balint’s Syndrome is known as simultagnosia. This is when a person is showing profound restriction of _____________, to the point that only one object or feature can be consciously observed at any moment
attention
The pulvinar is located in the posterior quarter of the human _____________.
thalamus
The pulvinar’s function is heavily involved in __________ processing and is important for the orienting & shifting of attention.
visual
The superior colliculus is located in the ____________ structure.
midbrain
The superior colliculus’s function is controlling the ____________________ of the eyes toward objects of attention and helps direct our gaze to attended objects & ensures that we don’t return to them too soon after our gaze has moved on. It also may help direct the covert attentional spotlight.
movement
Deficits that are seen after damage to the frontal lobe-
- struggle to prevent their gaze from being drawn away toward peripheral distractors while they’re performing a voluntary attention task
- persistent strange
__________, broken by bouts of euphoria (an exalted sense of well-being) - ordinary social conventions are readily cast aside by impulsive behavior.
- concern for the past or the future may be absent
- ____________________ is shown in may tasks requiring sustained attention
apathy, forgetfulness
The default mode network is a circuit of ________ regions that is active during quiet introspective thought.
brain
Inattentional blindness is the failure to perceive nonattended stimuli that seem so __________ as to be impossible to miss
obvious
Progressive supranuclear palsy is a rare progressive brain disorder that affects _______________, balance, and eye movements.
movement
Consciousness is the state of awareness of one’s own existence, ____________, emotions, and experiences.
thoughts
Perseverate is to continue any ____________ beyond a reasonable degree
activity
Executive function is a neural and cognitive ___________ that helps develop plans of action and organizes the activities of other high-level processing systems
system
Attention is a state or condition of selective _________________ or perceptual receptivity, by which specific stimuli are selected for enhanced processing
awareness
Covert attention is the attention in which the ________ can be directed independently of sensory orientation
focus
