Grayce Petruzzi Professor Chesire-Brown PSY-P 101 16 October 2015 Myth or Not? Before doing research on the topic if some people are “right-brained” or are “left-brained”, this statement means that if you are logical or analytical then you are left-brain dominant, while the creative and artistic types are right brain dominant. I believe this is a myth because the brain does use one brain region more than another for certain functions but does not support the statement above. For example, speech…

This particular episode of All in the Mind focuses on the hypothesis “Is being gay in your biology?” The research of three scientists focusing on what biological traits are different between gay people and straight people is presented in an easy to understand fashion. The first researcher we come across is Psychologist Dr. Richard A. Lippa. Dr. Lippa is looking for a link between gay people and their personalities by trying to figure out if genes play a role in the interests of gay people. One…

Neil Fleming’s VARK model that classifies people into visual, auditory, reading or writing, and kinesthetic learners. (Cherry, Kendra) I will look for connections between the types of learners and the handedness of my study participants. As the independent variable for all the experiments is handedness, and the dependent variable is the number of keywords for the reading test, number of activities going on in the picture for the visual test, number of keywords in the audio listening test, and…

Dissociative identity disorder, previously known as Multiple Personality Disorder, is the most severe, chronic manifestation of dissociation. It is characterized by the presence of two or more distinct identities or personality states that will recurrently take control of an individual’s behavior. Personality states, or “alters”, can be imaginary people or even animals. It is important to remember that DID is characterized by identity fragmentation rather than the proliferation of separate…

A review of the article, Caffeine Improves Left Hemisphere Processing of Positive Words written by Lars Kuchinke and Vanessa Lux (2012) hypothesized the “link between the left hemisphere (LH) will have a positive advantage in emotional word recognition” (p. 2). The increased dopamine in the brain and caffeine administered is anticipated to increase word recognition by enhancing the process of positive words by the effects of caffeine. This study help others’ understand how the left hemisphere…

After writing several high school essays, I always seem to get the comment from a teacher, “improve handwriting,” or “hard to read.” I therefore create this to explain the plight of being a member of ten percent of the world’s population, the left-handed. Handwriting alone is not the only thing that plagues the left-handed; it is the righty-controlled society that is forced upon them. From scissors, to spiral notebooks and whiteboards, lefties have been left out. I was born into a family…

Ancient Roman Superstitions The ancient Roman culture was very similar to the ancient Greek culture in many ways, including their use of superstitions to explain occurrences in their everyday lives. Science was still new and unclear during the time of the ancient Romans, since their culture was initially based off of what the ancient Greeks before them had discovered. The Romans came up with some superstitions that we would consider outlandish today, but actually are the origin of common sayings…

Introduction The human brain can be divided in terms of its structure as well as function. Structurally under the cranium of any human being exists a brain with two plainly visible parts, each about the size of a fist, known as the right and the left hemispheres of the cerebral cortex. Even though these two hemispheres appear identical in terms of structure, they perform distinct functions. Split-brain studies and cognitive research has indicated that the left hemisphere is associated with…

observations of the same issue. This is a sole reason why scientists take multiple data sets in order to weed out these inter-observer errors. It can affect the end result, or calculation resulting in human bias. They are very similar, as my handedness quotient was 60 which is closer to 100 than to 0 (Ambi) which relates to my limb dominance which is “Extreme Right Handed.” They measure accurately as I’ve always perceived myself as being extremely right handed. One of the differences I…
