Theories Of Psychology

Improved Essays
The word psychology is made up of by two greek words “Psyche” which is mind or the soul and “ logos” which means the study. The modern day definition of psychology is the scientific study of the mind and human behavior. Psychology is now recognized as a natural science but unlike other natural sciences such as chemistry, physics there is no one corrects theory or answer. Therefore we could state that psychology is a multi perspective science in which behavior and thinking patterns are explained in terms of different models and theories that have been explained by different schools of thought.
There are many approaches or perspectives in identifying or studying human behavior. The study of human behavior would be based on observing, interviewing

Biopsychologist attempts to explain human behavior using biological concepts. There view is the behaviour is inate and in nature. They explain that a persons behavioral pattern are due to the complex information processing system that takes place within the neurons, the biological structure and function of the brain, the genes and the endocrine system. Normal behavior as well as abnormal behavior is explained using biological reasons. Adolescent years of a person life are when the biological transformation takes place from a child to an adult with puberty. Puberty is the period where the biological changes take place where the body matures and is capable of sexual reproduction. During this period there is increase in hormone generation such as testosterones and estrogen. Aggressive behavior in teenagers could be explained due to the abnormalities in neurotransmitters, the abnormal function of brain or due to …show more content…
Neurons are individual cells in the nervous system that receive, integrate and transmit information. Neurons work as a chain but neurons are not connected to each other therefore information is communicated by chemicals generated in the neuron. The information is transmitted from one neuron to another neuron at synapses ( which is the gap between two neurons.) by the release of neuro transmitters which are chemicals that are stored in small pockets. Researchers have found that neuro transmitters are a critical factor in human behavior and there are nine main neuro transmitters and 40 other neurotransmitters which manages the complex functions of the human body.
One of the nine neuro transmitters which is serotonin which is known to regulate sleep and wakefulness, appetite, anxiety, depression, aggression and compulsive disorder. Therefore in a teenager if there is an abnormal low level of neurons generating low levels of serotonin it could lead to aggressive behavior in teenagers.
Dophamnie which is another neurotransmitter which controls voluntary movements, pleasurable emotions in the nervous system is also linked to aggressive behavior when abnormally high dorphamine levels are releases from the synapatic

    The pre-frontal cortex of the brain is responsible for planning, reasoning and, most importantly in consideration to aggression, impulse inhibition. Whether or not a person behaves aggressively may well be a factor of whether or not they are able to successfully resist the urge to be aggressive. Serotonin is implicated in this mechanism as, in normal levels, it seems to have a calming inhibitory effect on neuronal firing in the pre-frontal cortex (Cases, 1995). Therefore, low levels of serotonin may disrupt the calm inhibited firing of neurones, with the result that individuals are less able to resist the impulse to be…

    Regulatory Behavior Paper The nervous system is in charge of receiving and relaying the information that is collected; it is also in charge of monitoring and responding to both the internal and the external changes that help to control and coordinate the body’s functions. The sensory stimuli is able to become more apparent with the help of a strong and productive nervous system; this would include any change in emotion, memory or the environment. Neurons are known as the messengers of the body.…

    Estimating the speed of neural transmission from hand-ankle (treatment A) and hand-hand (treatment B) Introduction A neuron is a specialised cell transmitting nerve impulses and its function is to transmit information within the nervous system which is a network of nerve cells and fibres which transmit nerve impulses between parts of the body. Neural transmission occurs when a neuron is activated (sends out an electrical impulse). Activation of a neuron takes place when the neuron is stimulated by pressure, heat, light, or chemical information from other cells. Each neuron receives an impulse and must pass it on to the next neuron and make sure the correct impulse continues on its path.…

    Action Potential

    Action potential is an event that is carried out by a neuron from the dendrites to the soma, then the axon carries the action potential to its terminal buttons, and finally a neurotransmitter will be released. The neurons will send information, so it can travel down the axon and away from the body of the cell. The main goal of an action potential is to have a thought be created by the end of the process. A depolarizing current is created when an action potential explodes with electrical activity. It is important to remember that the transferring of ions across and through the axon walls leads to an action potential.…

    Experiments allow researchers to intervene and change behavior. Experiments also allow researchers to examine more than two variables at a time. Correlation studies, on the other hand, allow researchers to observe patterns that are not manipulated as they are in experiments. Correlations studies also only allow two variables to be observed at one time so that “the direction and strength for the association between the two variables” (Noba, 2014, p. 37) can be determined. As stated above, experiments allow researchers to intervene and change behavior by altering the independent variables and observe or measure the changes in the dependent variable.…

Wilhelm Wundt first began research for psychology psychologists have developed from around the world to bring us five main perspectives of psychology, known as, the five schools of thought. The five schools of thought help people to understand why people do certain motions, how people interact with each other, where we develop our mannerisms, and to have a deeper understanding of the human mind, through: biological, psychodynamic, behavioral, cognitive and humanistic perspectives. Biological psychology is the study of the physiological bases of behavior, which follows “the relationship between psychological processes and the underlying psychological events” (Britannica,…

    The brain is the most complex organ the human anatomy has. There has been plenty of research done on the brain and how it works and its general functions, but psychologists have only reached the tip of the iceberg. Psychology is used to research and understand the human mind. Now at the end of the day the overall question that is asked in the field of psychology, is why do people do what they do. Unfortunately due to the actual science and process on how to conduct research in psychology being fairly new, there is not much evidence to answer this question.…
