Two experimental procedures designed to provide empirical evidence for inhibitory conditioning during classical conditioning are the Summation and Retardation tests. Inhibitory Conditioning (CS¯) refers to prevention or reduction of a conditioned response (CR) due to the presence of a conditioned stimulus (CS). The Encyclopaedia of the Sciences of Learning defines conditioned inhibition as “conveying information that a possible future event is less likely than it would be otherwise”. Consequently the CS¯ is used as a signal to predict the absence of the CR, where it would be expected to usually occur. The CS¯ is thus used to inform us that something will not happen, comparatively to the excitatory stimulus (CS⁺) which conveys that something …show more content…
To be put crudely, inhibitory conditioning is the inhibition of a conditioned response. Dawson and Reardon (1969) found that the GSR of college students was significantly higher for the facility group than the inhibitory group, indicating the reduction in a CR, due to inhibitory forces. Moreover during conditioned inhibition if two different conditioned stimuli are present, whereby one is excitatory (CS⁺) and another a putative conditioned inhibitor (CS¯), the presentation of both simultaneously will eventually inhibit a CR. Initially the organism may respond to the combination of the two CSs, however it will soon learn that this is unnecessary, as the CSs are no longer followed by the US. The inhibitory force thus increasingly gains …show more content…
Initially the CS is repeatedly presented without the presence of an US, thus the CS becomes a putative conditioned inhibitor. Subsequently the CS is then repeatedly paired with a US. One can then conclude that if the stimulus is a conditioned inhibitor, with regards to the retardation test, the acquisition of excitatory strength will be retarded, due to the initial suppression of a CR. Consequently the delay of a CR can be compared to another CS that has been repeatedly paired with the US, to highlight the difference in the time taken to acquire an excitatory state between the stimuli and provide empirical evidence to support inhibitory conditioning. Conclusively if the CS takes longer to acquire excitatory strength when paired with a US, than a comparison CS, it is evident that it was conditioned inhibitor to begin
Following classical conditioning the data show a decrease in variability and in the latency between stimulus presentation and the response. There is also a change in trend from increasing to no trend.
The idea that "The Fall of the House of Usher" is in part an investigation into sexual motivation and sexual guilt complexes has often been hinted at but never critically pursued as the dominant theme in the tale. But such a reading is at least prepared for in important essays by D. H. Lawrence and Allen Tate which make the essential recognition that "The Fall of the House of Usher" is a "love" story (1). Lawrence and Tate, however, mistakenly attempt to purge the love concerned of all physical meaning. What they see Usher wanting is possession not of Madeline's body but her very being (Lawrence, p. 86). Theirs is essentially an anti-biological reading of the tale in which
The theory of Classical Conditioning is one based on the idea that an individual can learn a new form of behavior simply from the process of association. Or simply put according to the Encyclopedia Britannica, “Classical Conditioning occurs when two stimuli are linked together to produce a new learned response” (“Classical,” 2015, para.2). In order to better understand Classical Conditioning, it is important to first define several key terms. A stimulus is any feature of the environment that affects behavior. A response is the behavior elicited by the stimulus (“Stimulus,” 2015, para.1).
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
There are two learning processes that are used, classical condition and operant conditioning. One learning process used is classical conditioning. Classical conditioning is a learning process in which a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response. I found two TV commercials that are excellent examples for classical conditioning. The first commercial I found is an Old Spice commercial. The ad starts off with an attractive man in a bathroom telling women to compare the men in their lives to him, stating that if men would stop using girl body wash they could be like him. The ad then moves to a boat where the man in the commercial offers the women in the audience two tickets to something they would enjoy and diamonds and then states that anything is possible if men used Old Spice as a body wash to smell like a man, not a lady. The second commercial I chose is a Nike advertisement. Throughout the advertisement there are young, attractive, fit, and famous people working hard to succeed.
Respondent conditioning occurs when a neutral stimulus is paired with an unconditioned stimulus. The unconditioned stimulus elicits an unconditioned response, such
“Classical conditioning is a type of learning in which a stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus”.
Reinforcement is the main contributing factor in operant conditioning. There is more than one way to go about establishing reinforcement, if a delay occurs between the response and the reinforcement the response may not become strengthened. It is likely that if the reinforcement occurs immediately after the response that there will be a definite strengthening of the response. Continuous reinforcement is when reinforcement occurs at every instance of the desired response. Intermittent reinforcement occurs when a response is reinforced some of the time. The different schedules of reinforcement influence patterns of response. Intermittent schedules offer greater resistance to extinction than continuous schedules.

The process of classical conditioning follows the procedure from Pavlov’s salivation experiment. Before conditioning, when a bowl of dog food is presented the dog would “naturally” salivate at the mouth “in response to food”. Because this response occurs “automatically” and “prior training” isn’t required for hunger, this reaction is called an unconditioned response (UCR) which “is the response that is naturally elicited by the [UCS]” (Powell et al., 2013, pp. 112-115). When referring to a natural response--one is referring to an elicited reaction that is characterized as “an unlearned or innate reaction to [a] stimulus” (Powell et al., 2013, p. 115). Furthermore, the dog food is considered an unconditioned stimulus (UCS), which “is a stimulus that naturally elicits a response” (Powell et al., 2013, p. 115). According to Pavlov’s experiment, when a bell chimes without the presentation of dog food, the dog will not instinctually salivate (Powell et al., 2013, p. 112). Since the bell didn’t initially “elicit salivation” naturally, it’s called a neutral stimulus (NS) (Powell et al., 2013, p. 112). However, through conditioning, as the bell tone pairs with dog food continuously, the dog begins to salivate. Finally, after the conditioning process is completed, the pairing of “food” and the bell “now elicits salivation” (Powell et al., 2013, p. 112). Since the dog’s salivation required some type of continual prompting or, “prior training”, it’s reaction is considered a conditioned response (CR) “and the [bell]” is the conditioned stimulus (CS). By definition, a conditioned stimulus “is any stimulus that, although initially neutral, comes to elicit a response because it has been associated with an unconditioned stimulus” (Powell et al., 2013, p. 115). Responses triggered by a
This is called operant conditioning. Operant conditioning typically has both a reinforcer and punishment. A stimulus that increases the occurrence of a response is a reinforcer. As to presenting an unpleasant stimulus to decrease the occurrence is a punishment. An example of a negative reinforcement would be the car beeping to signal to fasten a seatbelt. Some of us are quicker than others to put on a seatbelt when first entering a car. If that car signals that you have not put on your seatbelt in a timely fashion, you may hear that annoying “ding ding” as a reminder. Until your seatbelt is fastened, the annoying noise will continue as a negative stimulus. Now, in the future if you’re ever in the car and you fasten your seatbelt immediately because you want to avoid the “ding ding”, you may just realize it’s just because you have been conditioned to do
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,
Learning theories are the structural foundation used to label how information is processed, stored and encoded during learning. Retention of knowledge is subjective and influenced by outside factors such as, an individual’s cognitive ability to process or retain information. Other influences are environmental, emotional or preexisting experiences or associations (Andreassi, 2000). To gain a better understanding of behaviorism in correlation to learning theories it is crucial to understand and grasp the meaning of associative learning. This process involves the association between two stimuli or a behavior and a learned stimulus. Associative learning is divided in to two central techniques, classical conditioning and operant condition. Classical and operant conditioning are basic methods of learning and conditioning is used to adapt a behavior or association through a stimuli or consequence (Ciccarelli, 2012). While classical conditioning and operant conditioning are key elements in associative learning, they have significant differences. A clear contrast between the two theories is whether the behavior or response produced is considered to be voluntary or involuntary.
Classical conditioning is a type of associative learning which occurs when two stimuli are paired together repetitively and therefore become associated with each other eventually producing the same response. Classical conditioning was developed from the findings of Ivan Pavlov to account for associations between neutral stimuli and reflexive behavior such as salivation. Pavlov (1927) accidently discovered that dogs began to salivate before they had tasted their food. To support his theory, he carried out experiments using dogs which involved measuring the amount of saliva they produced. In his experiments, food started off as an unconditioned stimulus (UCS) which produced salivation, an unconditioned response (UCR). They are both unconditioned as they occur naturally without being learned. The dogs were presented with a bell (NS), this provided no salivation. The bell and food were presented together and after many trails an
Classical and operant conditioning are two important concepts central to behavioral psychology. While both result in learning, the processes are quite different. In order to understand how each of these behavior modification techniques can be used, it is also essential to understand how classical conditioning and operant conditioning differ from one another. Both classical and operant learning are psychological processes that lead to learning. Here learning refers to the process by which changes in behavior, including actions, emotions, thoughts, and the responses of muscles and glands,
