PSY 200 STUDY EXAM 2 GUIDE ALL QUESTIONS
AND ANSWERS SURE A+
✔✔What is fMRI? - ✔✔functional magnetic resonance imaging
scanner measures blood oxygen level-dependent (BOLD) signals
✔✔Cons of EEG - ✔✔coarse spatial resolution
caps not always inclusive for all hair types
✔✔Pros of fMRI - ✔✔great spatial resolution
can identify networks of regions associated with a task
✔✔Cons of fMRI - ✔✔low temporal resolution
indirect measure of neuronal activity
✔✔How is behavior research overlooked? - ✔✔Because neuroscience has more
quantitative and technology driven findings, it is often invested in more than behavioral
research, even though we have learned more about the brain through behavioral
studies than from neuro research.
✔✔sensation vs perception - ✔✔Sensation is arrival of info to brain, perception is
interpretation of info in the brain
, ✔✔What is sensory adaptation? - ✔✔diminished sensitivity as a consequence of
constant stimulation
✔✔Define synesthesia - ✔✔a condition where people experience involuntary
perceptions that cross over sensory modalities.
✔✔What is the likelihood principle? - ✔✔We perceive the more likely object to cause an
image
✔✔list three challenges of visual perception - ✔✔visual ambiguity
inverse projection problem
invariance
✔✔What is visual ambiguity? - ✔✔one object could be perceived as multiple different
objects
✔✔What is the inverse projection problem? - ✔✔an image on the retina can be caused
by an infinite number of objects
✔✔What is invariance? - ✔✔the same object looks different from every angle
✔✔What is the blind spot? - ✔✔the point at which the optic nerve leaves the eye,
creating a "blind" spot because no receptor cells are located there
✔✔What are the 5 Gestalt Principles? - ✔✔proximity, similarity, closure, continuity,
simplicity
✔✔Define the gestalt principle of proximity - ✔✔things that are close to one another
seem to belong together
✔✔define the gestalt principle of similarity - ✔✔people tend to group stimuli that are
similar
✔✔define the gestalt principle of closure - ✔✔People will group elements to create a
sense of closure or completeness
✔✔define the gestalt principle of continuity - ✔✔objects with smooth edges are seen as
continuous
✔✔define the gestalt principle of simplicity - ✔✔people assume the simplest objects
possible
✔✔What are the cultural differences in the Muller-Lyer illusion? - ✔✔the illusion is more
pronounced in western cultures, possibly due to living in a "carpentered world"
