Pattern recognition-a cognitive phenomenon

MindMesh

Why do we instantly recognise a friend in a crowded place? Or the rhythm of a familiar song? The answers to these simple questions lie within a psychological and neuroscientific cognitive phenomenon known as pattern recognition. In this article we will explore the science behind pattern recognition.

What is pattern recognition?

Pattern recognition is a cognitive process that allows us to identify, interpret and understand patterns in our environment which allows for recognition of objects, sounds and other stimuli. It helps shape learning and decision-making. Neuroscientific research suggests that pattern recognition is enabled by neural plasticity which is the brain’s ability to reorganise itself after experiences. 

Pattern recognition works by allowing neural networks in the brain to deft regulations in the input they receive which helps us recognise patterns.

The different types of pattern recognition are:

• Visual pattern recognition which involves identifying patterns in visual stimuli such as recognising shapes and colours. This occurs in the visual cortex within the occipital lobe which is responsible for identifying visual stimuli.

• Auditory pattern recognition which involves identifying patterns in sound such as recognising and understanding a language. This occurs in the auditory cortex within the temporal lobe which is responsible for analysing speech based information and process sound including pitch, volume and rhythm.

• Mathematical pattern recognition which involves identifying patterns in numbers, shapes and sequences such as identifying rules like arithmetic or geometric sequences in numerical sequences. This occurs primarily in the visual cortex and hippocampus. The hippocampus is responsible for memory formation and it allows for recognition of patterns based on past experiences.

Are there any drawbacks to pattern recognition?

Although pattern recognition is generally effective as it allows for learning and decision-making. It also has a few downsides to it. 

 Cognitive bias is a major drawback of pattern recognition. It is an unconscious mistake in thinking that causes people to misinterpret information. One example of cognitive bias is pareidolia. Pareidolia is the tendency to perceive familiar patterns where there are none such as seeing animal shapes in clouds. It is mainly rooted in the brain preference for something familiar and this can lead to false assumptions. Another form of cognitive bias is confrontation bias which is  the unconscious tendency to selectively recognise patterns that align with our pre-existing beliefs ignoring and/or devaluing contradictory information.

In conclusion, pattern recognition is a fundamental process that allows us to interpret and identify familiar stimuli.  It helps us learn new information and improves decision-making. Although it is highly effective, it is best to note that it also has its own limitations. Understanding the strengths and limitations of pattern recognition can help improve accuracy and avoid misinterpretation which in turn would help in decision-making.
