PSY 402 (PSY402)

PSY-402 Topic 4 DQ 2 Describe blind sight and unilateral neglect and explain the contribution of these phenomena to researchers’ understanding of consciousness and attention. Class, Unilateral spatial neglect occurs when the attention network of the brain is only affected on one side which can cause the affected person to only be able to describe or produce a picture depicting only their perception of that particular side of themselves, the room etc. (Gazzaniga, Ivry, & Mangun, 2014). When ...

PSY-402 Topic 4 DQ 1 Compare and contrast early and late selection models of attention, and provide examples of each. Class, The models of attention refer to the theories surrounding how much of what is going on around an individual is perceived consciously when their attention is focused elsewhere (Gazzaniga, Ivry, Mangun, 2013). The early models held that the perceptual system did not process information equally and could, before an awareness occurs, be rid of any irrelevant information and...

PSY-402 Topic 3 DQ 1 Choose a perceptual difference that demonstrates an irregularity or dysfunction in one of the projection pathways. Explain how it could affect everyday life Class, Achromatopsia is a fancy way of saying color blind. A color blind person usually inherits this gene which has produced an abnormality in the photoreceptor system (Gazzaniga, Ivry & Mangun, 2013). Dichromat refers to those who are color blind who can only see two pigments of color: red and green if they are miss...

PSY-402 Topic 2 DQ1 What does the case of Phineas Gage reveal about localization of functions in the brain? How can modern neuroscientists and psychologists learn from his injury? Class, The case of Phineas Gage has revealed much to the sciences. Within the topic of neuroscience, many have researched the case of Phineas Gage, but a study done in 2012 looked specifically at the recovery of Phineas Gage rather than the injury. Phineas Gage’s recovery had setbacks, but the fact he lived and we...

PSY-402 Topic 1 DQ2 Describe two methods of research for studying neural function (describe at least one that uses the behavioral or cognitive approach). How do these methods complement one another? What are the limitations of each method? Class, Both the MEG or magneto- encephalography and the electrocardiogram or ECoG are methods of research used to study the neural functioning and both use the behavioral approach. The MEG creates small magnetic fields. Neurosurgeons are able to localize wh...

PSY-402 Topic 1 DQ1 Describe the emergence of cognitive psychology and neuroscience – what prompted the development of these fields, and what is significant about the shift from behaviorism to cognitive psychology and neuroscience? What can we understand about human behavior because of neuroscience that we could not have understood before? Class, The development of the neuroscience and cognitive psychology fields began with ideas that were either entirely rejected right from the get go ...
