  2. Classical conditioning - Wikipedia

    en.wikipedia.org/wiki/Classical_conditioning

    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).

  3. Measures of conditioned emotional response - Wikipedia

    en.wikipedia.org/wiki/Measures_of_conditioned...

    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.

  4. Alternate ending - Wikipedia

    en.wikipedia.org/wiki/Alternate_ending

    An alternate ending (or alternative ending) is an ending of a story that was considered, or even written or produced, but ultimately discarded in favour of another resolution. Generally, alternative endings are considered to have no bearing on the canonical narrative.

  5. Conditioned emotional response - Wikipedia

    en.wikipedia.org/wiki/Conditioned_emotional_response

    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 ...

  6. Latent learning - Wikipedia

    en.wikipedia.org/wiki/Latent_learning

    One significant example of classical conditioning is Ivan Pavlov's experiment in which dogs showed a conditioned response to a bell the experimenters had purposely tried to associate with feeding time. After the dogs had been conditioned, the dogs no longer only salivated for the food, which was a biological need and therefore an unconditioned ...

  7. Rescorla–Wagner model - Wikipedia

    en.wikipedia.org/wiki/Rescorla–Wagner_model

    Van Hamme and Wasserman have extended the original Rescorla–Wagner (RW) model and introduced a new factor in their revised RW model in 1994: [3] They suggested that not only conditioned stimuli physically present on a given trial can undergo changes in their associative strength, the associative value of a CS can also be altered by a within-compound-association with a CS present on that trial.

  8. Discrimination learning - Wikipedia

    en.wikipedia.org/wiki/Discrimination_learning

    Examples of discrimination learning in everyday life can include grocery shopping, determining how to decipher between the types of bread or fruit, being able to tell similar stimuli apart, differentiating between different parts while listening to music, or perhaps deciphering the different notes and chords being played.

  9. Extinction (psychology) - Wikipedia

    en.wikipedia.org/wiki/Extinction_(psychology)

    In classical conditioning, when a conditioned stimulus is presented alone, so that it no longer predicts the coming of the unconditioned stimulus, conditioned responding gradually stops. For example, after Pavlov's dog was conditioned to salivate at the sound of a metronome, it eventually stopped salivating to the metronome after the metronome ...
