parallel processing psychology definition: how our brains think
Parallel processing is a cognitive process that allows us to simultaneously process multiple pieces of information. This is in contrast to serial processing, which is a more linear way of processing information.
In parallel processing, different parts of the brain are able to work on different tasks at the same time. This allows us to do things like drive a car while talking on the phone, or listen to music while reading a book.

Origins of Parallel Processing
The concept of parallel processing originated in the early days of cognitive psychology. In the 1950s, psychologists began to study how the brain processes information. They found that the brain is not a single, monolithic system. Instead, it is made up of many different parts, each of which is responsible for processing different types of information.
For example, the visual cortex is responsible for processing visual information, the auditory cortex is responsible for processing auditory information, and the motor cortex is responsible for processing motor information.
These different parts of the brain work together in parallel to process information. This allows us to perform complex tasks, such as driving a car, playing a musical instrument, or having a conversation.
Parallel processing is a fundamental principle of how the brain works. It is essential for our ability to think, learn, and remember.
How Parallel Processing Works
Parallel processing is a way of processing information that divides the task into smaller, more manageable chunks. These chunks are then processed by different parts of the brain at the same time.
For example, when you are driving a car, your brain is processing a lot of different information. You need to be aware of your surroundings, you need to be able to control the car, and you need to be able to think about where you are going.
Your brain divides up this task into smaller chunks. For example, one chunk might be responsible for processing the visual information that you are seeing. Another chunk might be responsible for processing the auditory information that you are hearing. And another chunk might be responsible for processing the motor information that you need to control the car.
This allows your brain to process information much faster than it would if it had to process everything one chunk at a time.
Here are some examples of parallel processing in the brain:
- When you are reading, your brain is processing the visual information from the text, the auditory information from the sound of your voice, and the semantic information from the meaning of the words.
- When you are playing a video game, your brain is processing the visual information from the screen, the auditory information from the sound effects, and the motor information from your controller.
- When you are having a conversation, your brain is processing the visual information from the other person’s face, the auditory information from their voice, and the semantic information from the words they are saying.
Parallel processing is a very important part of how our brains work. It allows us to process information quickly and efficiently, which is essential for our everyday lives.
Automaticity
Automaticity is the ability to perform a task without having to consciously think about it. This is a key feature of parallel processing, as it allows us to do multiple things at the same time.
For example, when you drive a car, you are able to perform many tasks automatically, such as steering, changing gears, and monitoring the road. You are able to do these things without having to consciously think about them, which allows you to focus on other tasks, such as listening to the radio or talking to a passenger.
Automaticity is developed through practice. The more you practice a task, the more automatic it becomes. This is why it is often difficult to learn a new skill, but once you have learned it, it becomes much easier to perform.
Automaticity can be helpful in many situations. It can help us to be more efficient and productive, and it can also help us to avoid accidents. However, it is important to be aware of the limitations of automaticity. If we become too reliant on automaticity, we may be less likely to notice problems or errors.
Limits to Parallel Processing
Parallel processing is a powerful cognitive ability that allows us to process multiple pieces of information at the same time. However, it is not a perfect system. There are limits to how much information it can process at once.
For example, if you are trying to listen to two different conversations at the same time, you will probably only be able to follow one of them. This is because your brain can only focus on so much information at once.
Here are some of the limits to parallel processing:
- Attentional resources: Parallel processing is limited by the amount of attentional resources that are available. If you are trying to process too much information at once, you will not be able to focus on any of it effectively.
- Working memory: Parallel processing also depends on working memory. Working memory is a limited-capacity system that stores information that is currently being processed. If your working memory is overloaded, you will not be able to process new information effectively.
- Complexity of the information: The complexity of the information also affects the limits of parallel processing. If the information is very complex, it will take more time and attention to process, which will limit the amount of other information that you can process at the same time.
In general, parallel processing is a powerful cognitive ability that allows us to do many things at once. However, it is important to be aware of its limits. If you are trying to process too much information at once, you will not be able to do any of it effectively.
Conclusion
Parallel processing is a complex and fascinating cognitive process that allows us to process information simultaneously. This allows us to do things that would be impossible if we had to process information serially, such as driving a car while talking on the phone or reading a book while listening to music.
However, parallel processing is not a perfect system. There are limits to how much information it can process at the same time, and it can sometimes lead to errors. For example, if we are trying to focus on two different tasks at the same time, we may not be able to give either task our full attention. This can lead to mistakes or accidents.
Despite these limitations, parallel processing is a vital part of our cognitive abilities. It allows us to function in the world and to do the things that we need to do. As we continue to learn more about how parallel processing works, we may be able to find ways to improve our ability to process information and reduce the risk of errors.
