Acquisition In Psychology: Definition With Examples

Acquisition
(Last Updated On: August 14, 2017)

Acquisition refers to an early stage of the learning process during which time a response is first established. At this point in learning, the subject will begin displaying the behavior when a stimulus is presented, so we can then say that the behavior has been acquired.

In classical conditioning, acquisition refers to when the previously neutral stimulus becomes associated with the unconditioned stimulus and comes to evoke a response when presented. At this point, the unconditioned stimulus becomes known as the conditioned stimulus.

How Does Acquisition Work?

So how exactly does the acquisition process take place? Let’s take a closer look at classical conditioning itself to see how new learning and behaviors are acquired.

Classical conditioning begins by taking a previously neutral stimulus and repeatedly pairing it with the unconditioned stimulus. The unconditioned stimulus is something that naturally and automatically produces a response without any learning.

For example, imagine that you want to teach a rat to fear the sound of a cat hissing. You might start pairing the sound of a hissing cat with a loud bang. The loud bang will naturally lead to a fear response in the rat.

You go through this repeatedly, each time sounding the hiss and then the loud bang. Eventually, an association will be made between naturally frightening sound and the sound of the cat.

When the rat responds with fear to the sound of the hissing alone, you can now say that acquisition has occurred.

Factors That Can Influence Acquisition

As you might imagine, acquisition is not always a perfectly smooth process and there are many factors that can influence the strength and speed with which acquisition occurs. A few things that might influence the acquisition process include:

  • What is being taught can play a role. It is easier to train a person or animal if the behavior is something that they are naturally primed to acquire. For example, a person is more likely to acquire a fear of snakes than a fear of feather dusters.
  • How often an association is made. The more frequently a pairing is made, the stronger the response is likely to be.
  • When the stimulus is presented. If the unconditioned stimulus and neutral stimulus are presented too far apart, learning is less likely to occur. If it does occur, the response may be much weaker.
  • The relevance of the stimulus. If the stimulus is completely unrelated to the behavior that is being learned, it may take longer for acquisition to take place.
  •  How noticeable the stimulus is. If the stimulus is easy to miss, acquisition is less likely to occur or may only occur after many pairings have been made.

In our earlier example, you would want to make sure that the rat could hear the sound of the cat hissing and then be sure to perform repeated pairings with the loud bang. After a number of pairings, you might notice that the rat displays the desired behavior, meaning the response has been acquired. Once the behavior has been acquired, you can then begin to work on strengthening the response.
