Learning Flashcards
What is classical conditioning?
animals acquiring reflective behaviours (involuntary) through a process of association
What is learning?
learning is the change in an organism’s behaviour or thought as a result of experience
Describe pavlov’s experiment with the dogs and the association that was made
pavlov used classical conditioning to turn a neutral stimulus such as turning on a light into a conditioned stimulus which was salivation in dogs. the reason why the dogs did this was because they made an association between the light and food. they learned that whenever the light goes off, they will shortly be getting food
What is classical conditioning used alot in? why is it so powerful?
classical conditioning is used alot in advertisements to associate a pleasurable feeling or feeling of happiness towards some sort of stimuli (product theyre trying to sell) for example, coca cola commercials associating their drink with feelings of happiness. its powerful because its involuntary and we dont realize we are being conditioned this way
What is the idea behind blink conditioning?
to compare how quickly humans acquire a behaviour versus other animals
How does blink conditioning work? what is involved?
you present a neutral stimulus (sound, light..etc), and you present a stimulus which causes the animal to naturally blink. Once this is done a couple of times, the animal will associate the neutral stimulus with the stimulus that causes it to blink and therefore will blink to the neutral stimulus
What does the result of blink conditioning tell us about classical conditioning?
That its universal amongst species if the behaviour produced is the same as well (e.g. animals that blink, will present the same classical conditioning results as all other animals that blink)
What are the 4 factors that play a key role in classical conditioning?
- The UCS (unconditioned stimulus)
- the UCR (unconditioned response)
- The CS (Conditioned stimulus) … was previously a neutral stimulus
- The CR (Conditioned response)
What is acquisition?
acquisition is the period of time where the association between a CS and UCS is being learned by the animal
What is the term used to describe each pairing attempt to the CS (neutral stimulus) and the UCS?
learning trials
How can someone turn a neutral stimulus into a conditioned stimulus?
By pairing it with an unconditioned stimulus multiple times
Why is there 2 kinds of salivation occurring in UCR and CR?
in UCR, salivation is natural and unconditoned (not learned) by the animal. But, when salivation (or the same behaviour produced from a UCR) gets produced as a result of association with a neutral stimulus, THEN its considered to be a CR, because its learned and not natural. One key difference is the quantity of the response, for example, in Pavlov’s dogs, they will salivate at food (as a UCR) and salivate at a sound of a bell before the food (CR), but the amount of saliva produced differs when they’re exposed to the food (UCS) directly than when they’re only hearing sound or anticipating food
What is forward-short delay pairing and what is forward trace pairing?
Forward short delay is presenting the CS (e.g. tone) shortly before presenting the UCS (eg. food)
Forward trace pairing is presenting the CS on and off until the UCS is presented
What is the most effective method of learning and what is the least?
The most effective method of learning is the simultaneous pairing which is presenting the CS and the UCS at the same time. the least effective is backwards pairing where the UCS is presented first and then the CS is presented after
What is habituation and what is its adaptive significance?
Habituation is the decrease in strength of a response to a repeated stimulus. By not responding to uneventful or familiar stimuli, organisms conserve energy and can attend to more important stimuli
What is sensitization and why would you want to sensitize to the repeated presentation of a stimulus?
Sensitization is the increase in strength of a response to a repeated stimuli… it occurs in strong stimuli (for example, extremely loud sounds). Its purpose is to increase responses to potentially dangerous stimuli
Explain the key factor in producing extinction of CR?
Extinction trials is trying to get rid of the CR. It is done when a CS is presented repeatedly in the absence of a UCS which results in the weakness and eventual disappearance of the CR. Extinction trials are a series of trials that are done by presenting the CS without the UCS
Explain the adaptive significance of stimulus generalization and discrimination?
Generalization is when an animal responds or produces a CR to a stimuli that is similar to the initial CS. Its beneficial for preventing danger in some animals.
Discrimination is when the CR is limited to only one stimulus but not to others. Its best if the animal learns to distinguish between stimulus that can harm or cause danger and stimulus that dont
Explain the process of higher order conditioning?
Higher order conditioning is when a neutral stimulus becomes a CS after being paired with a CS that has already been established. Example: if you already paired a sound going off (CS1) with getting food (UCS), then you can apply higher order conditioning and turn on the light (CS2), and then apply the sound (CS1) and then present the food (UCS) and soon the animal will associate the light going off for food. However, Higher order conditioning produces a weaker CR than the initial CS and is easily extinguished
how does classical conditioning explain fear acquisitions?
Fear can be explained by classical conditioning as pairing an unpleasant UCS with a CR. For example, if you develop a fear of driving after you have gotten into a car accident, you are actually pairing an unpleasant event with a neutral stimulus like cars or driving.
