The Theory Of Perception As A Physical Chemical Process

Perception can be understood on the model of change. Aristotle started off by stating the explanation of perception as a physical-chemical process by atomist philosophers at that time ‘like is affect by like’ alleging that chemical elements in us meets the like elements in the things we perceive. If we do have the same elements inside our sense organs, it is then questioned as to why the sense-organs do not perceive themselves i.e. why doesn t the eye see itself or why do part of the eye not see the other parts of the eye; why do they not produce perception without an external object? Aristotle then implant his explanation - that senses themselves are potentials and it is to be activated with something actual. With the example of wood as a fuel having a potential to be a fire but will not become so until something external â€Å"activates it† and burns it. The same way as man having the potential to sense but can only do so when something external makes them activ e. The activation process turns potentiality into actuality. To be affected or to be moved requires something active, like the wood example. Activity, the fullest kind of actuality, brings about this change. This change is then explained with the â€Å"like/unlike† theory. A thing can only be changed by a thing that’s unlike itself â€Å"for it is the unlike which is affected†. For example, a red cloth cannot be changed by a red dye; a drink of the room temperature cannot be heated nor cooled by the temperature of the room -Show MoreRelatedRational Choice Theory: Criminology901 Words   |  4 PagesChoice theory was born out of the perspective of crime causation which states that criminality is the result of conscious choice. This theory is also known as the rational choice theory. According to this theory, the choice whether or not to commit a criminal act is the result of a rational thought process that weighs the risks of paying the costs of committing a c rime, against the benefits obtained. In other words, if the benefits--monetary or otherwise--outweigh the risks of sustaining the costsRead MoreMotivation and the Brain1249 Words   |  5 Pagesin which the brain and physical function are involved through emotional and reflexes. It is a critical factor in learning, emotions, and success of an individual. It is also influenced by emotional state of a person as the evaluations and actions of a living being are closely derived through motivation. The emotional systems are also associated with the creation of motivation. Brain is the major factor influencing the emotions and working process of an individuals perceptions of various events.

Substance abusers can use chemicals to cope with psychological anguish, social pressure, be biologically susceptible or to create an illusion of purpose.

The basic process that occurs in the sensory perceptual system begins with a physical energy from the living organism’s environment. Then the phylogenetically engineered external organ is used in order to collect the energy from the environment. Receptor cells are then stimulated and create electro-chemical reactions. Electrical impulses are encoded with information and travel the neural net. It will then beRead MorePain, Acute Pain And Chronic Pain1627 Words   |  7 Pagesdistress or agony. It may be steady or throbbing. It maybe stabbing, aching or pinching. In the past, many people thought that pain was a result of a damaged tissues. However now the researchers have come to find out that pain is an intricate process that might or might not include tissue damage and most likely involves social, psychological and emotional factors, which can either cause, increase, or decrease painful sensations. There are two types of pain, acute pain and chronic pain. AcuteRead MoreOriginal Writing : Sister Callista Roy1315 Words   |  6 Pagesin sociology from the University of California. Roy was confronted with a challenge to establish a nursing conceptual model, which she accepted. Roy had noticed, throughout her nursing, that children were able to adapt to key psychological and physical changes. Roy decided to use adaptation as the basis for a nursing conceptual model. Roy’s outline of the adaptation model was accepted by Mount Saint Mary’s College in 1968, this is when Roy began creating the model of adaptation.

Communication in the brain occurs via neurons which transmit electrical impulses to other neurons by neural conduction (Wickens, 2009). They are connected by synapses which are small gaps between two nerve cells. There are approximately one billion neurons in the brain (Wickens, 2009), meaning that there are even more synapses. Synapses allow electrical impulses to be passed from neurone to neurone as chemical messages in the form of neurotransmittersRead More`` Architecture And The Crisis Of Modern Science ``1637 Words   |  7 Pagesexperience between the architectural object and the audience of it should be complimentary.

Nursing. Introduction Nursing theory is a belief, policy, procedure proposed or followed as the basis of the action. It is used as the basis to organize framework of concepts and purposes designed to guide the practice of nursing. Nursing theory started in the 1800 when emphasis was on nursing education. Most of the nursing theories were proposed by nurses with input from other nurses or other health care professionals. As nurses
