Assignment 3 Written Essay Questions 1. a) We are able to experience different types of sensations because our nervous system encodes messages. German physiologist Johannes Muller in his doctrine of specific nerve energies described a kind of code which is anatomical. In his doctrine, Muller explains that different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways that lead to different areas of the brain. For example, when the ear receives signals, these signals cause impulses to travel along the auditory nerve to the auditory cortex. And signals from the eye cause impulses to travel along the optic nerve to the visual cortex. Because of these anatomical differences, light …show more content…
An extensive matrix of neurons in the brain gives us the sense of our own bodies and body parts. Pain results when this matrix produces an abnormal pattern of activity, as a result of memories, emotions, expectations or signals from various brain centres and not just from signals from peripheral nerves. Because of the lack of sensory stimulation or a person’s efforts to move a nonexistent limb, abnormal patterns may arise, resulting in phantom pain. 6. a) The role stimulus generalization plays in this problem is where mental images of the sights and smells of the clinic can become conditioned stimuli for nausea, aside from the nurse’s uniform, smell of rubbing alcohol or the waiting room. b) High order conditioning can be illustrated in this problem of vomiting and nausea where a patient who drank lemon –lime Kool-Aid before their therapy sessions developed anxiety disorders. They continued to feel anxious even when the drink was offered in their homes rather than at the clinic. c) Classical conditioning could help patients reduce pain and anxiety through the use of placebos. For example the use of pills and injections that have no active ingredients or treatments that have no direct physical effect on the problem. The bigger and more impressive the placebos are, the stronger their psychological effects are. 7. The evidence shows that punishments are
In classical conditioning, there are four critical elements: the unconditioned stimulus, the conditioned stimulus, the unconditioned response, and the conditioned response. The unconditioned stimulus (US) is a stimulus that causes a response before any conditioning, and an unconditioned response (UR) is the way something reacts to an unconditioned stimulus (text, p. 256). In my example, the US would be bad bacteria, and it resulted in the UR of nausea. A conditioned stimulus (CS) involves a neutral stimulus (NS), something that didn’t originally cause a reaction, becoming something that causes a conditioned response after a connection is made to the US (text, p. 256). In my example, the
Psychology explores human behavior and the human mental process figuring ways to improve the thinking and attitude of an individual’s existence. Sometimes, different techniques are used and tried to properly resolve the problem within the multitude of possible behavioral issues. Moreover, Sigmund Freud, an Austrian neurologist, developed many theories, psychodynamic therapy, for clinically treating people with mental health problems through their unconscious mind; Then, Sigmund Freud’s theories or therapy, rather, diverged into other types of therapies such as Biological Psychology or Cognitive Psychology. No doubt, there are various perspectives, both strong and weak, in the field of Psychology using different techniques on different
Birbaumer, Lutzenberger, Montoya, and Wolfgang (1997) examined the functional relationship between cortical reorganization and phantom limb pain. Neuroelectric source imaging was used to determine changes in cortical reorganization in the somatosensory cortex after anesthesia of an amputation stump produced by brachial plexus blockage in six phantom limb pain patients and four pain-free amputees. This cortical reorganization was studied to examine whether the neurons rewired after the loss of an appendage. Three of the phantom limb subjects experienced a virtual elimination of current phantom pain. The Biraumber et al., (1997) result of the anesthesia was a very rapid elimination of cortical reorganization in the somatosensory cortex. In three phantom-limb-pain amputees pain was not reduced by brachial
Much of what we do, we learn from experience. We behave the way we do because of our learning associations with the environment. Thus, through college life and its requirements, students naturally feel anxious while speaking in front of a group. This behavior is called a classically conditioned behavior, in other words, a learned response from experience. I feel anxious while giving a speech and I have learned by experience that I will always be anxious, so I can anticipate my natural response when speaking in front of a group.
In previous studies, Frank and Byram’s article suggest that taste and smell interactions are dependent on taste and odor. In their experiments, they gave subjects strawberry
With regards to classical conditioning, I believe my fear of roller coasters can be traced back to my childhood. I am 8 years old, standing beneath a behemoth structure, ready to conquer the beast they called
Since psychology in high school, the way the brain continues to works has constantly fascinated me. Like how does an organ that only weighs 3 pounds on average have the power to control our entire body? It’s shocking, and my curiosity towards it just continues to grow. So, with the Neuroscience major I knew I could take more of the classes that would allow me to learn everything I wanted to understand. Being interdisciplinary, I get aspects of Biology, Psychology, and Chemistry, thus allowing to me to get the full picture about mechanisms within our body.
I started my education in Erie, Pennslyviana.I attend McDowell High. I would say that we were one of the richer schools were I live. I am going to talk about my first assignment Brainology. I thought it was very interesting and it thought me a lot about how some people have different mindsets.
Garcia et al research (Mazure, 2004) proves otherwise, as he shows rats initially made to drink the saccharine-flavoured water, injected with the poison after a delayed interval between the drinking and the drug, developed aversions to the saccharine flavoured water even after 24hours of delay. This illustrates, even when the CS-US is delayed, learning takes place and the ability to do so is adaptive in all species supporting that a general process learning theory is effective. The rat’s biological make-up has an innate tendency to associate illness with the taste of food previously eaten after one trial. Pairing a light with a paw shock, on the other hand, takes several trials to acquire and has low tendency to associate illness with visual or auditory stimuli. Whereas the rats are more likely to associate a painful event like shock with external auditory and visual than with taste stimuli. This revolves around preparedness and we can say that the laws of learning may vary with preparedness of the organism for the association and for those different physiological and cognitive mechanisms (McGowan, & Green, 1971). Louge (1981) also supports taste aversion as a classical conditioning biological constraint learned behaviour on humans as he carried out a questionnaire which resulted in students declaring they were aversive to certain foods. Characteristics, such as smell, sight and texture were also discovered.
The concern about life is a main human characteristic. No matter if his concern is concentrated in himself or in persons or things that surround him and constitute his environment, everybody wants to know why people, himself included, behave the way they behave. Everybody, also, wants to improve his behavior, so as to live in harmony with himself and the society.
“The aversion therapy is considered a type of psychological treatment, where patients will be exposed to different types of stimulus and at the same time it will experience some type of discomfort (Lieberman, 2012).”This treatment is based on the principles of classical conditioning; using classical conditioning to get rid of addictions or unwanted behaviours. Patient’s unwanted addiction is paired with a drug that makes them sick.
A virtual rat, Sniffy, was used for this experiment. Sniffy the Virtual Rat, Pro Version 3.0 allows for the demonstration of Pavlovian and operant conditioning of a virtual rat. Tom Alloway, Greg Wilson, and Jeff Graham, authors of Sniffy the Virtual Rat designed this program to be an affordable alternative for students to gain “access to the main phenomena of classical and operant conditioning that courses on the psychology of learning typically discuss” (Jakubow, 2007). The program allows for simulations for Pavlovian conditioning such as acquisition, extinction, spontaneous recovery, stimulus-intensity effects, compound conditioning, blocking, overshadowing, overexpectation, inhibition, sensory preconditioning,

Biological psychology, of biopsychology, is the application of the principles of biology to the study of mental processes in terms of bodily mechanisms. The view that psychological processes have biological (or physiological) correlates, is the basic assumption of the whole field of biological psychology. Biological psychology is a hopeful domain, one that has much to offer in terms of improving the quality of life of the healthy as well as those suffering from disorders. It also contributed important therapeutic data on a variety of conditions, including: Parkinson 's Disease, Alzheimer 's Disease, Clinical depression, Schizophrenia and a lot others. Humans have very complex nervous system, they use neurons and neurotransmitters to make the highest active communication network throughout the body. “most of the body’s neurons are found in the central nervous system(CNS), which consists of the brain and spinal cord” (psychology 5th edition). “Neuroscience emphasizes that the brain and nervous system are central to understanding behavior, thought, and emotion. (Van Horn, 2014; Zhao & others, 2014). Therefore, for biological psychologist all that is psychological is first physiological. All thoughts, feeling & behavior ultimately have a biological cause.” We are benefited from biological approach for diagnosing and treating human brains Ex. Schizophrenia. Scientists are also able to create medications for different types of illnesses. Besides having psychologists
Classical conditioning effects everyday life especially in relation to phobias and addiction which will be discussed in this essay. Classical conditioning was founded by Ivan Pavlov. He believed that if a behaviour can be learned, it can also be unlearned too. This essay will highlight the importance of conditioning principles in explaining and treating problem behaviours. Classical conditioning has revolutionised behavioural therapies, such as flooding and systematic desensitisation to treat phobias, and aversion therapies to treat addictive behaviour.
