What is the difference between blocking and interleaving.
Blocking is studying one subject at once, while interleaving is studying multiple at the same time.
What term is used to describe a finding generalizing in a laboratory used in the real world.
External Validity
Localization of function in the brain.
The theory that different parts of the brain are responsible for different mental processes.
What is a MRI
Magnetic Resonance Imaging is a non-invasive medical imaging device. Radiation free.
What does EEG measure?
Electroencephalogram measures brain waves.
What is the Gestalt principle?
Explains how the brain organizes visual perceptions into groups, patterns.
What’s the difference between top down, and bottom up?
Top down starts with the end goal and works its way back, while bottom up starts with the little things and work towards the goal.
What is stimulus masking? What is it for?
It is a pattern or noise used to partially or completely obscure a target stimulus, preventing it from being consciously processed or recognized. It is used in experiments to study visual perception, short-term memory, and consciousness by manipulating how much a subject can “see” the target.
How does the Dorsal stream operate. Is it vulnerable to illusions?
Enables precise actions by mapping visual space in real-time, independent of conscious perception. It is resistant to illusions.
What is a disorder where the person has trouble seeing motion.
Akinetopsia
What is visual agnosia?
A person can clearly see an object but can’t recognize or identify what that object is
What is apperceptive agnosia?
The inability to perceive or for a stable mental representation of objects, despite being able to see.
Split brain patients
If a patient is shown something in their left visual field, they will not be able to verbally name it, but they can identify it with their left hand.
If julie sustains damage to her ventral stream what happens?
Her “what pathway” is damaged and she will have impaired object recognition, and facial recognition.
What is Early selection vs Late selection.
Early selection proposes that a filter acts before semantic analysis, selecting information based on characteristics.
Late selection argues that all stimuli are processed for meaning, and then selection occurs.
What are Automatic processes?
Processes that are fast efficient and unconscious. (Heart beat, blink)
What is task switching and mental set?
Taask switching is rapidly switching between tasks, while relying on someones mental set. (frontal cortex)
What is the central bottleneck?
The point in which mental capacity is found and can no longer go further.
What is underload view and depletion view?
Underload view attributes performance decline to low stimulation, while depletion view attributes performance decline to exhaustion.
What does exogenous mean?
Outside factors or influences.
What are tasks used to study attention?
Stroop, SART, Visual Search Tasks, Posner Cueing Task.
Why does task switching occur?
Because the brain can’t focus on multiple high level tasks simultaneously.
What is Gordon Logan’s Instance theory of automatization?
Automaticity isn’t a result of restructuring, it is a memory based retrieval process.
What causes the stroop effect.
A conflict in the brain between automatic, overlearned tasks, and slower controlled tasks.
