Fear is a powerful human emotion. It can make you do things you wouldn’t normally do, like risk taking and bad choices. Fear can spike your adrenaline. For example if someone was to lift a car off a run over child, that would be caused by adrenaline, which is caused by fear. According to several studies done by physicians

Written by Oxford English Dictionary, fear is an unpleasant emotion caused by the threat of danger, pain, or harm, and is an emotion that is programmed into all animals and people as an instinctual response to potential danger. Fear isn’t always adaptive though. For example, a small amount of fear before an important speech serves a purpose. It encourages you to focus on your topic and avoid embarrassing yourself. This is a type

Background (key works): Reinforcement theory is rooted in theory of operant conditioning based primarily on the work of the American behavior scientist B.F. Skinner (Borkowski, 2011). In contrast to Ivan Pavlov’ respondent conditioning controlled by

The classical conditioning model was one of the first theories used to describe phobias. Many years ago, scientists observed that one could willingly elicit a fear response in an animal or human through systematic teaching. For example, if every time a rat is presented with a low buzzing noise, it is electrically shocked, eventually, when it hears the noise alone (with no shock), it will exhibit symptoms of fear.

Studying parts of the brain that are involved in dealing with fear and stress also helps researchers understand possible causes of PTSD to begin formulating a plan to treat PTSD. The amygdala is known for its role in emotion, learning, and memory. The amygdala appears active in learning to fear an event as well as in the early stages of fear extinction. In storing extinction memories and dampening an existing fear the prefrontal cortex, which is involved in problem solving, decision making, and judgement, is seemingly

Two prominent researchers, B.F. Skinner and Albert Bandura, have developed theories which provide differing perspectives and explanations regarding the learning behavior of individuals. The purpose of this writing is to explore the theoretical perspectives of Operant Conditioning Theory developed by B.F. Skinner and Social Learning Theory developed by Albert Bandura. An overview of both theories is presented, followed by a discussion of their similarities and differences.

Fear is something that large amounts of people have encountered at least once at some point in their lives. It has been said to have caused a variety of outcomes, many of them being largely negative. Therefore, it is a common human response to react to fear by counteracting it with positivity and/or success. The idea people have of what fear is depends on the person. In the article “How Fear Works”, for example, fear is defined as a “chain reaction in the brain that starts with a stressful stimulus and ends with the release of chemicals” (Layton 1). The website “Psychology Today” defines fear another way, calling it “a vital response to physical and emotional danger” ("Fear Paranoia”). There are several other definitions people have on the

Fear. What exactly is it? For me, it’s the twisting in my stomach, the uneasiness that’s starting to rise up from my belly to my throat, the knots slowly forming into a bundle of nerves, and all the anxiety that comes along with it. In this paper, I will be discussing my learning experience with my fear of roller coasters and analyze them with the perspective of learning theories. I will analyze my learning experience(s) with regards to classical conditioning, operant conditioning, and observational learning. This is how I learned to be afraid of roller coaster(s).

The parabrachial nucleus is a center for regulation of physiologic manifestations of fear avoidance and anxiety 83. These connections develop information about whole body rotation and position with respect to gravity. This information is linked to threat assessment pathways via connections between parabrachial nucleus and the central nucleus of the amygdala 85. Connections between amygdala and superior colliculi and between amygdala and thalamus link visual and somatosensory inputs to threat assessment pathways 86. Sensory inputs and assessment of threat converge in the hippocampus, dorsolateral prefrontal cortex, the insula, and anterior cingulate. These four structures are components of both the limbic and the vestibular cortex 87. Vestibuloparabrachial network and amygdala-locus coeruleus outputs

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,

Arguably, an organism is better described as an information seeker, forming relations amongst events from information provided by a stimulus. For example, Rescorla suggests that contiguity is an insufficient example of Pavlovian Conditioning. As shown in simple CS/US parings, learning was determined by how the two stimuli differ, not in what they share, showing that contiguity is not a necessity, (Rescorla, 1988). Furthermore, systematic fear conditioning scenarios imply the base rate of US occurrence against a CS/US contiguity is also sensitive to conditioning. Evidence for this can be found in previous work that validates the current conclusion. Rescorla (1968, p. 1), argues that contingency over contiguity is an important determinant of fear conditioning, and refers to contingency as the “relative probability of occurrence of US in the presence of a CS as contrasted with its probability in the absence of CS.” Rescorla’s (1988) adaptation of these results measures asymptotic fear levels, (where each curve shows conditioning as an increasing function of the likelihood of receiving a shock during the tone), supporting the continued importance of perceived fear in associations. Furthermore, results from studies on Blocking, Conditioned Inhibition and Auto-shaping in pigeons suggest that the simplistic notion of previous theory

Fear can create an instinctual response to perceived danger. A good example is of the time my husband and I were alone on a long hike in the jungles of Belize and came upon a fer-de-lance snake that would most likely have killed us with its bite. Without any time passing, my instinct of fight or flight emerged and I pushed my husband out of the way, telling him to run as I did. Also, in an instinctual state of fear, someone can perform tasks they did not think were possible such as being able to lift a

A biological constraint in learning theory refers to an inherited tendency to learn and create certain relationships, and it has been said that some species are much more readily than others in learning such behaviour. Therefore it involves the factors which make populations resistant to evolutionary change and the animals biological make up. In this paper I will attempt to explain the bases of the original biological approaches to learning in classical conditioning in humans and animals, make comparison between animals and the association of fears

Having a "bad experience" causes us to later be stressed in that situation, i.e. pairing a neutral stimulus with a painful, scary experience will condition a fear response to the previously neutral stimulus. Fears and other weaknesses may yield payoffs; the payoffs (like attention or dependency) cause the fear to grow. Avoiding frightening situations may reinforce and build fears and stress.
