How do we make decisions, remember faces, plan our day? What happens in our brain that allows us to learn a new language, focus in a noisy setting or solve a puzzle? These everyday tasks all involve mental processes, which cognitive psychology helps us understand.
Cognitive psychology is the branch of psychology that studies human thinking and processing [1]. It explores the way we perceive the world around us, how we pay attention, remember experiences or learn a new skill. This helps us understand how these mental processes influence behaviour, emotions and learning [2-3]. It has become one of the most versatile approaches in psychology, with far-reaching applications like psychotherapeutic interventions, teaching strategies and artificial intelligence (AI) software [2].
The History Of Cognitive Psychology
Cognitive psychology started growing between the 1950s and the 1970s. At the time, it challenged the then-popular behaviourist approach, in what would later be known as the “cognitive revolution”. Behaviourists, who studied psychology, only focused on behaviour that could be observed or seen, not thoughts or emotions. While they were aware of such internal processes, they referred to them as the “black box” whose workings should not be studied, as they could not be observed or measured [3].
The cognitive revolution rejected that idea. Psychologists took a new approach and argued that mental states and processes could – and should – be scientifically studied [4]. The cognitive approach started using more rigorous and scientific research methods, using experiments and data to study how the mind responds to specific experiences or situations. It focused on internal processes like memory, attention, perception and learning, as well as how these impact our behaviour.
Around the time of the Second World War, early cognitive psychologists applied this newfound knowledge in areas like military aviation. For instance, they redesigned cockpits after discovering that pilots often confused two very similar levers with different functions, leading to crashes during takeoff. Given the significant progress that computers made in the 1940s and 1950s, psychologists also started to compare the human mind to computer processes, which helped them further understand how we take in, store and use information4.
Important Names In Cognitive Psychology
Several important figures developed theories that are still influential today and helped to further establish this new approach in psychology, which would be named Cognitive Psychology by Ulric Neisser in 1967 [4]. Noam Chomsky played a key role by challenging the view that language is learned only through reinforcement and repetition. Instead, he proposed that we have a universal structure for language hardwired into our brains, which helped shift psychology towards studying the mind³.
Jean Piaget theorised that children progress through four developmental stages in a fixed, successive order—never skipping stages or returning to earlier ones [3]. Aaron Beck led groundbreaking research in the field of depression, highlighting the role of cognitive factors in the treatment of mental health issues [5].
Collectively, these contributions emphasised how important our thoughts and mental processes are for understanding behaviour. They helped shape the field of cognitive psychology and paved the way for innovations in many other fields.
Cognitive Psychology Topics
Topics covered by cognitive psychology are varied and include:
- Attention
- Perception
- Memory
- Language
- Problem solving
- Decision making
- Reasoning
- Cognitive development
- Learning
- Metacognition
What Is CBT?
Cognitive Behavioural Therapy (CBT) is one of the most effective forms of psychotherapy and is widely used for the psychological treatment of mental health issues and disorders [6-5]. It was developed by Aaron Beck between the 1960s and 1970s [5].
His approach was based on the idea that the way our mind responds to a negative event affects our emotions and behaviour more than the event itself [6]. Once research demonstrated that CBT could rival the effectiveness of medication for depression, its popularity grew rapidly and it started being used for other mental health issues and disorders [6].
How Does CBT Work?
CBT is a structured, personalised and collaborative psychotherapy that focuses on restructuring thought and behaviour patterns [5- 7]. Specifically, it targets an individual’s perception of situations or “automatic thoughts”. Automatic thoughts happen quickly and often unconsciously. When they are inaccurate, unrealistic or negative, they can make everyday situations seem worse than they actually are [6- 7]. For example, assuming someone is upset with you when they don’t say hello.
In depression, this can cause a person to unconsciously pay more attention to negative events in their life, process information in a pessimistic light or distort their understanding of events, all of which increases their emotional distress. During CBT, the person learns skills that help them identify the unhelpful patterns, or “cognitive distortions”, behind unhealthy automatic thoughts and how to reshape them. They achieve this by developing their own emotional and coping tools, both in sessions and with homework exercises.
It is an incredibly versatile psychotherapy and has been successfully used with populations of all ages across mental health issues and disorders such as depression, addiction, anxiety disorders and post-traumatic stress disorder [5].
What Does A Cognitive Psychologist Do?
Many cognitive psychologists are active in research and academia, studying cognitive functioning and its influence on behaviour, such as the impact of sleep on decision making or the positive effect of music therapy on degenerative brain disorders [8.] They can also apply this research in clinical practice to treat mental disorders and cognitive issues. CBT is a well-known example, but they also provide memory or speech therapy after a traumatic brain injury or training methods in reading and writing for people with dyslexia [2,8].
Cognitive psychologists have also been active in other fields such as organisational psychology, marketing, engineering, software development or AI. For instance, cognitive psychologists are involved in educational contexts, by creating courses that consider cognitive principles to capture students’ attention and promote learning. Marketing experts might also use knowledge of attention and decision making to create engaging advertisements that attract customers to their product. In AI, understanding the human mind can contribute to developing models that mimic human processing and eventually surpass it.
Cognitive Psychology Careers
Specific career paths for a cognitive psychologist include:
- Academic researcher or professor.
- Clinical psychologist, particularly a cognitive-behavioural therapist.
- Human-computer interaction specialist.
- Cognitive rehabilitation therapist.
- Educational consultant.
- Forensic or legal consultant.
Conclusion
Cognitive psychology has transformed how we understand the human mind, from the way we understand and interpret the world around us, to how we remember information and solve problems. By shifting from focusing only on behaviour to studying the thoughts and mental processes that precede it, psychology made important advances that had varied applications. It introduced Cognitive Behavioural Therapy, which remains one of the most widely applied research-based treatments for many mental health conditions.
What we have learned from studying cognitive processes has influenced many other areas, like teaching, healthcare, marketing or AI technology. Cognitive psychology has thus become an influential field that continues to help us understand and improve the human experience.
