The Garcia Effect
Explain the theoretical significance of the phenomenon known as the Garcia effect.
Does this phenomenon have any practical significance for animal or human behavior?

The Garcia effect or conditioned taste aversion is an example of classical conditioning of an animal's thought to link a taste with a symptom brought on by toxic substance causing nausea. It has had great significance in the understanding of human and animal learning. It shows that learning has a biological link. It shows that animals and humans learn based on their evolutionary roots. A thought that was snubbed by many early psychologists whom thought that learning had no inbuilt predispositions and that humans were a ‘blank slate at birth' (R. E. Cornwell, C. Palme, P. M. Guinther, H. P. Davis, 2005). With nurture rather than nature being the only way a human could be shaped, a view which causes a lot of disagreement in science, coining the phrase ‘nature vs. nurture.'

This essay will talk about the significance of the Garcia effect and how it has had a great impact on modern psychological thinking. The basic of this impact showed a strong biological link to learning.

Looking more specifically the Garcia effect is the conditioning of an animal's behaviour to acquire a specific conditioned response (CR) brought on by a specific conditioned stimulus (CS). For example this method is used to train animals to perform certain tasks when they are given the corresponding stimulus. The Garcia effect has also been utilised to condition animals to act in an uncharacteristic way when the stimulus is presented. An example of this is shown when a mouse is fed a grape, then is immediately after given an injection to make it nauseous. The mouse will start to link the grape to becoming nauseous and therefore will refuse the grape whenever it's presented. Although the nauseous feeling isn't linked to the ingestion of the grape the animal will think that it is.

    Chapter 3 begins with a brief examination of the history of classical conditioning. The research of Pavlov, Twitmyer, Vul’fson and Snarskii is presented. The historical accounts are used as a basis for defining the classical conditioning paradigm. Several experimental situations, including fear conditioning, eyeblink conditioning, sign tracking, and taste-aversion learning, are described in detail. The specifics of excitatory and inhibitory conditioning are then presented. These specifics include definitions, conditioning and control procedures, and measurement of the conditioned responses. The chapter concludes with an examination of the prevalence of classical conditioning. Classical conditioning mechanisms involved in responses during causal judgment, food preference learning, nursing, and sexual behavior are presented.…

    During Pavlov's experiment dogs were hooked up to a machine that collected and measured saliva. He noticed that the dogs started salivating not only when offered food, but also in response to events immediately preceding the feeding. He referred to the salivation that occurred when the dogs where presented with food as an unconditioned response, an inborn reflex or instinct that did not require learning, caused by the presence of the food which he referred to as an unconditioned Stimulus; as food is necessary for survival it is instinctual to crave it. Through his experiments he discovered that if a particular neutral stimulus, with no inborn reflex response, such as a bell ringing, was combined with an unconditioned stimulus such as food then the dogs would learn to associate that Neutral stimulus with the Unconditioned Stimulus, and the neutral stimulus would trigger salivation on its own. The neutral stimulus had now become a conditioned stimulus, and the unconditioned stimulus a conditioned reflex,…

    A neutral stimulus (such as a bell) which normally wouldn’t produce a response (such a salivating) eventually becomes paired with another stimulus (such as the food) this is referred to an unconditional response. When the bell and food (unconditional stimulus) are paired often enough the dogs start to salivate as soon as they hear the bell and before the food is served. When this occurs conditioning has taken place. (Cited in Burns 1995) Pavlov argued that if dogs could be conditioned to salivate then it is possible to apply the process to bodily process that effect illness and mental health disorders. Nowadays classical conditioning is applied in the treatment of phobias and in aversion therapies.(Cited in Burns 1995).…

    John Garcia challenged the prevailing idea that all associations can be learned equally well. Garcia researched the effects of radiation on laboratory animals, and noticed that the rats began to avoid drinking water from plastic bottles in radiation chambers. At first he believed it was classical conditioning but after performing experiments John concluded it was taste aversion. Conditioned taste aversion occurs when a subject associates the taste of a certain food with symptoms caused by a toxic, spoiled, or poisonous substance. For example if you were to become violently ill after eating seafood, you probably would have a hard time eating it again. The taste and smell would become a conditioned stimulus for nausea. B.F. Skinner developed a behavioral technology that revealed principals of behavior control. Skinner designed an operant chamber, popularly known as a skinner box. The box has a bar or key that an animal presses to release food or water, and a device that…

    Classical conditioning was a theory developed by a Russian psychologist called Ivan Pavlov (1849-1936). He was working with dogs to investigate their digestive systems. The dogs were attached to a harness and Pavlov attached monitors to their stomachs and mouths so he could measure the rate of salivation. He noticed that the dog began to salivate when someone entered the room with a bowl of food, but before the dog had eaten the food. Since salivation is a reflex response, this seemed unusual. Pavlov decided that the dog was salivating because it had learned to associate the person with food. He then developed a theory. Food automatically led to the salivation response, since this response had not been learned, he called this an unconditioned response, which is a response that regularly occurs when an unconditioned stimulus is presented. As food automatically leads to this response, he called this unconditioned stimulus, which is a stimulus that regularly and consistently leads to an automatic response. Pavlov then presented food at the same time as ringing a bell (neutral stimulus), to see if the dog would learn to associate the bell with food. After several trials, the dog learned that the bell was associated with food and eventually it began to salivate only when the bell was rung and no food was presented. It therefore has learned the…

    However, Pollan says our brains are confusing the food we eat. The brain thinks of bitter foods as toxic and sweet foods as healthy, high energy foods. For example, he explains that “. . . some of the bitterest plants contain valuable nutrients, even useful medicines. We can’t rely on our sense of taste when we choose what we eat” (106). This argument shows that Pollan believes that the brain, while communicating with taste, misleads people into eating food that is not healthy. As taste largely impacts what humans eat, we should be aware of this fact, ignoring our senses and relying instead on…

    Behaviorism had many shortfalls with its primary one being that it excluded the effect of genetics entirely. It only accounted for what had been learned through reward and punishment only. Questions were raised and answers were missing when examining the question through the lens of behaviorism only. One area where ethologists observed discrepancies were in fixed-action patterns and critical periods in animals. Fixed-action patterns were behaviors that received little to no reward or punishment in which the animals engaged in and critical period referred to a specific period of time in which if a…

    Learning is an important skill that all organisms must acquire in order to survive or fall prey to Darwinism’s main idea of survival of the fittest. Learning is the long lasting effect of a change in behavior. This would constrict the application of learning conditioning to a few applications. The three most recognizable applications are classical conditioning, operant conditioning, and learning by observation. Each type of learning is different, but uses similar ideas such as an unconditioned stimulus, which is usually food, and an unconditioned response, which food is associated with salivation and hunger. There are several ways that an individual can condition an organism to learn skills through three different applications of learning: classical, operant, and observation.…

    By definition, classical conditioning refers to conditioning in which the conditioned stimulus is paired with and precedes the unconditioned stimulus until the conditioned stimulus alone is sufficient to elicit the response (Merriam-Webster, 2013). As a general concept, classical conditioning assists organisms in learning which stimuli signals are conducive to survival and which stimuli signals are detrimental to survival (Olson & Hergenhahn, 2009). As an example imagine that you decide to attend a road trip. You decide to have a fruit snack while traveling. The twisting and turning in your travels causes motion sickness and creates nausea. This leads to nausea every time you come in contact with a fruit snack, which leads to an avoidance of fruit snacks. This is a form of classical conditioning. Classical conditioning has been debatable in the science of psychology for years. It is the intension of this paper to describe, explore, analyze, and summarize the theory of classical conditioning. In this quest, the author also intends to hypothetically apply the theory of classical conditioning, including charts and explanations.…

    Watson defined behaviourism as “a natural science that takes the whole field of human adjustments as its own. It is the business of behaviouristic psychology to predict and control human activity” (Watson J, 2009). There are three different aspects to the perspective of behaviourism, classical conditioning, operant conditioning and social learning theory. Classical conditioning refers to an individual or animal learning through association. Research was carried out in 1909 by Ivan Pavlov. When he experimented on his dogs, they were offered food and saliva production increased. He also noticed something particularly interesting, salivation increased as the researcher opened the door to bring them the food. The dogs had now learnt the link between the door and their reflex response of salivation .Pavlov then added a bell into the equation, every time he fed the dogs he rung the bell, eventually the dogs would salivate to just the sound of the bell ringing. Pavlov had demonstrated classical conditioning through association (Eysenck, 2005).…
