Sensation & Perception 1
This part of the brain is most likely to be affected if someone has difficulty recognizing everyday objects despite normal vision.
What is the inferotemporal (IT) cortex?
When our brains perceive something to be really hot like when we eat capsaicin that's found in peppers or menthol that is found in mint that causes us to feel cold. What is that trickery of our senses called.
What is sensory illusion
These receptors in the eye help you see in detail during the light and in color.
Cones
In the case of a disease like Alzheimer's, Brain Lesions, and tumors. Diseases that affect processing information, spatial awareness, and self-perception. What part of the brain is most at stake for being damaged.
What is the parietal lobe
A scientist would want to test this theory by for example using a noise to see how we make decisions based on the sensory information. Examples you're in the shower and you think the phone is ringing what do you do, or you're driving, and you hear a clunk in the car what do you do.
What is signal detection theory
This is the detection of environmental stimuli based on your basic senses.
Sensation
In this form of processing, assumptions are made about what we expect to see.
Top-down processing.
This concept allows you to correctly perceive objects as remaining the same in their size, shape, color, and brightness across viewing conditions that yield different physical input to the eyes.
Object Constancy
This is the Gestalt law that says our mind forms outlines or boundaries around a triangle that are not there.
Completion
the minimum amount of a stimulation level to notice the difference between the two is called what.
Just Noticeable difference
The process of changing stimulus energy into neural impulses is
Transduction
The process of taking sensory info and assembling and integrating it.
Bottom Up Processing
This is the further processing of stimuli and how the brain interprets it as something meaningful
Perception
If a scientist was to keep turning up the volume until the observer can first detect it, what method is the scientist implementing here.
Method of Limits and Adjustments
What part of the brain would be active when taking information from our eyes and turning it into what that person sees
What is the Occipital Lobe
The minimum intensity of stimulation that must occur before you experience sensation 50% of the time
Absolute threshold
What sense is olfaction?
Smell
The minimum amount of stimulus intensity change required for that person to detect that change.
Difference threshold
Describes the amount of neurons in an area of the visual cortex are responsible for processing a stimulus of a given size.
Cortical Magnification
An explanation that splits into two parts which explained a previous law, that was meant to calculate a difference threshold of perceived magnitude and intensity.
Fechner's Law
The principle that for two stimuli to be perceived as different, they must differ by a constant minimum percentage.
Weber's Law
This explains why we don’t notice a sound that we’ve heard for a long time or a smell that we’ve smelt for a long time.
What is Sensory Adaptation
When looking at the perceived intensity of a stimulus is proportional to the physical magnitude of the stimulus what is the formula you would use.
Stevens Powers Law
When looking at two images the difference in the image between both eyes even though the image itself has not changed is
What is retinal disparity
Cells that respond to dark spots surrounded by a light background
Off center retinal ganglion cells
