As previously learned in class, the definition of evolution is the change in variant frequencies in a population over time. The four forces that evolution acts on are mutations, gene flow, genetic drift, and natural selection. From an evolutionary psychology perspective, the physical structure of the brain has changed over time, thus allowing humans to develop complex behavioral patterns. When comparing brains with primates, humans have a larger and heavier brain. When compared to a…

period of time (4). This increase in muscle length might be a great importance to a person with spastic cerebral palsy in lessening the amount of tension placed on joint structures and allowing them to have a greater range of motion. However, the clinical applications of this evidence are still unclear. Wiart, Darrah, and Kembhavi, in their review of the research on stretching in children with cerebral palsy, find that there is no clear consensus about how the muscle contracts and how stretching…

The ability to express and perceive emotion serves an important role for human functioning in everyday environments. It can, for example, allow us to detect danger or respond to a person in need. A full understanding of how emotion influences behaviour has yet to be realized. Recent literature has demonstrated that exposure to emotionally arousing stimuli can alter the perceptual mechanisms of participants. The present experiments attempted to expand this research to examine cross-modal vision…

Throughout Abnormal Psychology, we have learned different aspects that play a role in mental abnormalities that lead one to become more symptomatic. One specific element that has been very prevailing throughout this course is environmental factors. Although, genetic factors are a major part, one 's environment also plays an almost equal effect too. When observing individuals who are susceptible to mental illnesses or even those who already portray/acquire these illnesses, one can witness that…

Classical music is more harmonic while rock music is more rhythmic. Rhythmic music makes listeners more passionate, raising adrenaline, while harmonic music makes listeners more contemplative. Studies have shown that exposure to rock music causes learning and memory retention problems because the rhythm acts in the same way a drug do. However, the brain does create a strong association between rock music and what is happening visually when you hear the song. So, regardless of conditions, when…

Post-Traumatic Stress Disorder is caused by Psychological Changes in the Brain People who have been in combat overseas and have been involved in a traumatic or life threatening event often come home with some form of PTSD. Most soldiers will lie and tell people they do not have PTSD that they are fine. For those people who fear the stigma of PTSD following them the rest of their career. Scientific research will show Post Traumatic Stress Disorder is caused by psychological changes in the brain…

five parts of the brain involved with fear and the response to it. The thalamus receives incoming data and decides where to send it. It is located deep within the brain at the top of the brainstem and under the cerebral cortex, near the center of the brain. It is connected to the cerebral cortex, hippocampus, and spinal cord to receive sensory information. The sensory…

Study after study shows that any physical activity leaves behind many positive benefits but how much exercise does that imply and what kind of benefits are likely to be seen or even felt. There is no right or wrong answer although the Department of Health and Human Services recommends a minimum of 20 minutes everyday doing moderate aerobic activity such as walking or mowing the lawn combined with 10 minutes of vigorous activity related to running or sports while mixing in 2 days of weight…

The life expectancy of people with cerebral palsy are becoming progressively longer; research and services should take this into account as focus remains on the younger demographic whereas, a lifespan perspective is now required. Furthermore, supports and services can alleviate many of the…

My Reflection Paper While completing the first module for neurology there were many aspects of the brain that I was completely unaware of and found interesting. As a speech-language pathologist, it is important for one to know the function of the brain so one can have the skills to help improve the ability for an individual to communicate with others. Damage to certain parts of the brain function can lead to some drastic consequences relating to speech and language functions. I had always found…
