Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
The conditioned emotional response is usually measured through its effect in suppressing an ongoing response. For example, a rat first learns to press a lever through operant conditioning. Classical conditioning follows: in a series of trials the rat is exposed to a CS, often a light or a noise. Each CS is followed by the US, an electric shock.
In Pavlov's original demonstration of classical conditioning, he used a backward conditioning arrangement as the control condition. Briefly, in that procedure, the dogs experienced the same number of US presentations (food) and the same number of CS presentations (metronome ticking) as the experimental groups, but the timing of the CS and US ...
Then, there are more conditioning trials, this time with the light (CS1) and a tone (CS2) together with the US. Now, when tested, the agent does not salivate to the tone (CS2). In other words, an association between the tone CS2 and the US has been "blocked" because the CS1–US association already exists.
For example, in order to override antecedent 2, gain the students’ attention and immediately request something (e.g., a high five), before praising them and providing positive reinforcement. [15] This intervention fits in with the idea of classical conditioning, [3] as the child is rewarded with positive affirmation when they complete a task.
In the theory of classical conditioning, unconditioned stimulus (US) is a stimulus that unconditionally triggers an unconditioned response (UR), while conditioned stimulus (CS) is an originally irrelevant stimulus that triggers a conditioned response (CR). Ivan Pavlov's dog experiment is a well-known experiment that illustrates these terms.
Central to operant conditioning is the use of a Three-Term Contingency (Discriminative Stimulus, Response, Reinforcing Stimulus) to describe functional relationships in the control of behavior. Discriminative stimulus (S D) is a cue or stimulus context that sets the occasion for a response. For example, food on a plate sets the occasion for eating.
This would include, for example, remembering the name of someone or the aroma of a particular perfume. [1] This type of memory deals specifically with the relationship between these different objects or concepts. A normal associative memory task involves testing participants on their recall of pairs of unrelated items, such as face-name pairs. [2]
