Throughout the history of the science of psychology, researchers, clinicians, and theorists have all attempted to answer the question “what makes us uniquely human?” It is obvious to the untrained observer of nature how humans are different from other mammals in the animal kingdom: humans can think rationally and logically, have feelings and emotions, develop more slowly than any other mammal, and are able to work together on a massive scale to form sprawling civilizations. When one steps back…

In the daily lives of humans we often take our ability to see for granted. We rarely think about what process our eyes and brain must complete in order to view something as simple as a movie or lecture slide. In fact, such a small part of our anatomy is made of greatly complex procedures The operation system of the eye is very complex and one can easily stray from track when discussing how the eye works. First, the cornea is a part of the physical eye that helps reflect and bend light in a way…

Background and Significance In the past half century, the world populous has dramatically shifted from rural environments into urban centers. In 1950, as little as 30% of the world 's population resided in urban centers. Now, that proportion has risen to 50% and is predicted reach over 70% by 2050 (“World Urbanization Prospects: The 2014 Revision, Highlights”). This shift in the world 's populous has been termed urbanization, which is the increase in number of cities and amount of people that…

The damages that would lead to me believe that it occurred primarily in Broca’s area would be the aphasia that he is currently experiencing Broca's area is a region of the brain that’s is located in the frontal lobe of the left hemisphere witch is the dominant side of the brain and it’s functions is linked to speech production and language processing. It was first known as Paul Broca's witch he discovered in 1861 while examining the brains of patients with language difficulties. Apart from…

1) In the hippocampus, activity-dependent synaptic plasticity (i.e. LTP) plays a crucial role in certain types of learning. Therefore, the physiological saturation of synaptic weights should disrupt the encoding of new memories. Researchers defined saturation of an intrinsic pathway as “a neural state in which no further potentiation is feasible, at least for a period of time, at any site in the pathway.” In this experiment, researchers were testing if saturation of hippocampal long-term…

Is screen time damaging the teen brain emotionally? Ever heard of the Limbic System, Synaptic Pruning, or the Prefrontal Cortex? Synaptic Pruning, the Limbic System, and the Prefrontal Cortex all deal with the brain. In a way, they all have something to do with behavior. Screen time is bad not only for a teens brain, but for their health. The AAP should should not raise the time limited to screen time. Synaptic Pruning is a productive charge in neutral structures by reducing the overall number…

Nasometer What is it? A non-invasive, real-time, computer-software supported instrument that measures the acoustic energy of the nasal and oral cavity during speech tasks. Nasometry software collects and calculates the (nasal plus oral) data to determine a ratio converted to an average nasalance score. Nasalance Score: N ÷ (N + O) x 100.) Purpose: A tool to assess velopharyngeal function; including hyponasality, hypernasality, airway obstruction, and resonance disorders. Often used in cleft…

There are several theories about the cause aggression and violence. Researchers believe environmental effects during childhood prior to puberty can affect a person’s violent tendencies as an adult. Serious traumatic experiences or social or physical abuse in combination with high levels of MAOA leads to more antisocial and aggressive tendencies as an adult. High levels of MAOA alone do not predispose a person to aggression, but social and physical abuse trigger the MAOA gene leading to the…

Study of the brain is significant in gaining insights on its structural and functional design and mechanisms which help explain the cause of various existing neurological and psychiatric diseases (Kotter, 2001). Consequently, the histological study of the nervous system and its components which underlies the understanding of the brain forms the basis and foundation of neuroscientific research (Annese, 2012). Important components of the nervous system include the spinal cord which consists of…

Winner, E., Brownell, H., Happé, F., Blum, A., & Pincus, D. (1998). Distinguishing lies from jokes: Theory of mind deficits and discourse interpretation in right hemisphere brain-damage patients. Brain and Language, 62, 89-106. Purpose The purpose of the study was to investigate the deficits in the theory of mind in individuals with right hemisphere brain injury due to a stroke. The theory of mind is an “invisible mental state” through which a person can attribute mental states such as the…
