PSYC 230 UIUC TEST PAPER 2025 QUESTIONS WITH
ANSWERS GUARANTEE A+
✔✔Other uses of FFA - ✔✔FFA also activates when seeing a familiar car, familiar birds,
etc...
✔✔PPA - ✔✔Parahippocampal place area
Overall scene context:
- Outdoor vs. indoor scenes
- responds preferentially to places, such as pictures of houses.
✔✔What happens when the PPA is impaired? - ✔✔Topographic Agnosia
✔✔Extrastriate Body Area - ✔✔An area in the temporal cortex that is activated by
pictures of bodies and parts of bodies, but not by faces or other objects.
✔✔Grandmother Cells - ✔✔a hypothetical neuron that just responds to one particular
stimulus
✔✔Quiroga et al. (2005) - ✔✔- Did single cell recordings on patients about to undergo
brain surgery for epilepsy
- A particular neuron responded preferentially to Kobe Bryant (face or words) and a
separate famous neuron responded to Luke Skywalker-
- A particular cell fired to the Golden Gate Bridge, and it did not fire for the leaning tower
✔✔Face Inversion Effect - ✔✔people are much more accurate in identifying upright
faces, compared to upside-down faces
- Tells us that when we look at an upside down face, the normal face processing breaks
down because we're not used to seeing faces in this arrangement
- WITHOUT holistic processing (top-down), we end up breaking it down and just
assuming something is right
✔✔Capgrass Syndrome - ✔✔"label" recognition intact but "emotional" recognition
missing
- People usually have an emotional response automatically when seeing someone (ex:
loved ones)
- Sometimes believe that their loved ones have been replaced by an alien, because
they are not getting the emotional response immediately
- ONLY VISUAL, auditory voices recognized a "lovely" or "dangerous"
✔✔How can we tell what is a face and what isn't - ✔✔We have a high criterion for
recognizing animacy in a human face
- Can feel pain, has a mind, etc...
, ✔✔Accidental Viewpoints - ✔✔a viewing position that produces some regularity in the
visual image that is not present in the world
✔✔Heterochromatic Light - ✔✔white light, consisting of many wavelengths
✔✔Monochromatic Light - ✔✔light having a single wavelength or frequency
✔✔Spectral reflectance - ✔✔the proportion of light that a surface reflects at each
wavelength
✔✔Achromatic Lightness - ✔✔amount of light reflected by surface
✔✔3 Dimensions of Color - ✔✔Hue, Saturation, Brightness
✔✔Hue - ✔✔A quality or shade of color
✔✔Saturation - ✔✔intensity of color
/Purity of color
✔✔Brightness - ✔✔How much light is reflected by a color
✔✔Additive color mixing - ✔✔Adding different colored lights on top of each other,
putting more light in the mixture than exists in any one light by itself
- ONLY FOR LIGHTS
✔✔Pointillism - ✔✔Small dots of paint
- From a distance, the colors blend together like additive color mixing
✔✔Subtractive color mixing - ✔✔the process of mixing pigments, each of which absorbs
some wavelengths of light and reflects others
- Formation of colors by removing some wavelengths of light, leaving less light than was
originally there
- Making it more opaque
- ONLY FOR PAINTS
✔✔Color matching experiments - ✔✔By mixing intensity of three lightbulbs, can
participants match/recreate a given color patch
✔✔Metamer - ✔✔two lights that have different wavelength distributions but are
perceptually identical
✔✔Metameric matching - ✔✔M & L cones (red and green) excited, making yellow
- Exciting two different cones create the same response each time, allowing for
metameric matching
