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.

    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).…

    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…

    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).…

    The idea of classical condition is one of the most notable learning techniques because it involves a stimulus rewarded for a certain response. Naturally, animals and human have unconditioned stimulus that triggers an unconditioned response. The most common connection is the correlation between food and salivation. Food naturally draws organism to it in order to satisfy a drive created by hunger to acquire homeostasis. A response is created because of the organism’s reaction to food, which is usually salivation. Classical conditioning is considered an effective way to train an organism to learn habits not naturally associated with certain unconditioned stimulus. This creates a conditioned stimulus. The once unconditioned response is now conditioned to respond to the conditioned stimulus, which is called a conditioned stimulus. An example of conditioned stimulus and response is the example of associating the school bell with food. Children are hungry by nature, but when the school bell is added, the children are reinforced to associate the school bell with lunchtime. Classical…

    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…

    Raynor & Watson carried out a controversial experiment in 1920 using classical conditioning to try and understand the origins of different fears and phobias. They observed the behaviour of a boy named Albert and found that he took a liking to a white rat and did not demonstrate any fear when subjected to the rat; the only thing that he expressed any fear of was a loud noise which would make him cry. They combined the loud noise with the rat which he later developed a phobia of. Both experiments demonstrate the effects of classical conditioning.…

    The flaw in attempting to determine what degree of behavior is attributed to nature and what degree is attributed to nurture is that both of these perspectives play a role in how and why a behavior is exhibited. Some of the behaviors which individuals exhibit can be linked to animal or primal instinct, these are behaviors based on nature; however, we must consider that the primal fears we have as children such as fear of the dark, often no longer exhibited in the individual as an adult. This change in the behavior can be attributed to experience over time, the nurture perspective agrees with experience’s influence in behavior. (Pinel.(2009)).…

    Over the course of the last century one of the greatest debates in psychology concerns, the basis of behaviour, specifically whether behaviour is innate i.e. genetically controlled, or whether it is learnt through the socio-cultural environment. This is often referred to as the Nature vs. Nurture debate. There are two main arguments on this issue. The ‘Nativist’ claims that all behaviour is innate believing that genes control the majority of animal behaviour. On the other hand, the empiricist position suggests that all behaviour is learned through an individuals cultural experience and conditioning – that individuals begin life as blanks slates. Extremes of both these positions are reductionist, since they explain all behaviour at one level of explanation. This debate has evolved in such a way that the modern question is not whether behaviour is innate or learned, but rather how much of behaviour, if any, is genetically determined. Most psychologists now accept that both heredity and the environment are necessary for human existence and influence our behaviour. Therefore the question has shifted to considering to what extent nature or nurture affects our behaviour and how they interact– not so much nature or nurture, as nature via nurture. The debate endures because both sides have the ability to create a scientific environment to support their cause.…

    Classical conditioning and operant conditioning are learning styles associated with human behavior. According to Kowalski and Westen, (2011) “Classical conditioning is a procedure by which a previously neutral stimulus comes to elicit a response after it is paired with a stimulus that automatically elicits that response” (Kowalski & Westen, 2011, p. 164). Ivan Pavlov, a Russian physiologist studied the digestive system of a canine, when he came across the discovery of classical conditioning (Kowalski & Westen, 2011). In this learning experiment, he noticed that the canine salivated at the sign of food (Kowalski & Westen, 2011). The canine engaged in salivating when the food was present by a ringing of a bell (Kowalski & Westen, 2011). This experiment led to the canine salivating at the ringing of the bell even if there were no foods present (Kowalski & Westen, 2011). Psychologists refer to this as classical conditioning (Kowalski & Westen, 2011, p. 164). Counter…

    Garcia effect is a conditioned taste aversion. With the Garcia experiments, rats were given saccharine – sweetened water, causing nausea and illness to the rats. Through the experiments, the rats would avoid the taste after being presented with a new taste. Garcia 's discovery, conditioned taste aversion, is considered a survival mechanism because it allows an organism to recognize foods that have previously been determined to be poisonous.…

    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…
