PSY654 Exam #1 Questions With
Complete Solutions
In what way can highlighting help learning? - ANSWER Help learn a deeper
understanding of the most important things in the material
Name two limitations of highlighting. - ANSWER Those who highlight, remember it
worse.
Highlighting the wrong things; different from your prof.
What are diminishing returns of learning in re-reading? - ANSWER There is a certain
point where re-reading only works so much
At a certain point, there is not much more you can learn
When is re-reading better than testing? When is testing better than re-reading?
Describe an experiment that would demonstrate these patterns of results. - ANSWER
Rothkopf- re-reading
-After a few times of re-reading, there was no additional performance improvement
Roediger & Karpicke- self testing
-Read passages
-One group was allowed to reread and another was not
-5 min later took a test
-Rereading was better than just doing the test
-Having tested yourself previous helps more than rereading
Self-testing helps when studying days before to understand what you need to improve
on and what you know or don't know
Re-reading helps the night before a test or right before to try and memorize what you
already know
What part of the cerebral cortex is involved in creating a mental representation of the
space around you? - ANSWER Parietal lobe
Discuss the contributions that Santiago Ramon y Cahal and Edgar Adrian made to our
understanding of the structure and function of the brain. - ANSWER The brain
communicates through electrochemical communication
, Neurons are not necessarily connected
Measuring electro aspect down an axon
How do neurons code for the intensity of a stimulus? Are action potentials stronger for
more intense stimuli? Are action potentials fired more frequently for more intense
stimuli? Both? - ANSWER Fire at the same rate
The more intense the pain is the more it is firing
What was the significance of the work done by David Hubel and Thornsten Weisel? What
was the significance of the work done by Charles Gross? - ANSWER David Hubel and
Thorsten Wiesel (Feature Dectectors)
Occipital lobe processes visual information
Working with cats
Implant a micro electro into specific neurons in the visual cortex of the cat
Sensitive to different lines
Specific neurons only care for specific types of basic stimuli
What is the difference between specificity coding and population coding? Use facial
processing to make your argument. How does sparse coding build on the idea of
population coding? - ANSWER Sparse coding: processing faces, the neurons are all
devoted to processing separate features, neuron won't be used if the feature is
irrelevant to that face.
Specificity: each neuron in the fusiform cortex is involved with processing a specific
face (fires only when we see a face)
Population: all of the neurons in the fusiform cortex are processing specific features of
faces (fire at different times depending on the feature they have)
What part of the brain is involved in processing faces? - ANSWER Inferior temporal lobe
(fusiform)
What is prosopagnosia? - ANSWER -How they dress how they walk and talk etc
-Inability to recognize faces
How would one demonstrate causation in a study aiming to demonstrate the effects of
drug use on brain structure? - ANSWER Testing to see the damages overtime in the
brian
Seeing brain activity before and after the drug
How do researchers commit 'reverse inference' when interpreting the results of brain
imagining experiments? - ANSWER The goal of reverse inference is to infer the
