Psychology & Mental Health Vocabulary

20 essential psychology and mental health words in English with definitions and example sentences — ideal for B2–C1 learners preparing for IELTS, academic writing, or professional conversations.

Psychology vocabulary is increasingly important for everyday English as conversations about mental health, wellbeing, and human behaviour become more common in workplaces, schools, and the media. When you replace vague phrases like “feeling bad” with precise terms such as anxiety, depression, or trauma, you communicate far more clearly and show a sophisticated command of the language. These words appear regularly in IELTS reading passages, academic essays, and news articles, making them essential for B2–C1 learners.

One of the most important things to understand about psychology vocabulary is the difference between clinical and colloquial usage. Words like depression and phobia have precise medical definitions, but native speakers also use them in everyday conversation with looser meanings. Recognising this distinction — knowing when someone means a diagnosed condition versus a general feeling — is a sign of true language competence. Similarly, terms like cognitive and subconscious appear frequently in academic texts but require careful handling to avoid sounding unnatural.

Many psychology terms also combine with specific nouns and verbs that are worth learning as collocations. You experience anxiety, seek therapy, build resilience, develop a mindset, and show empathy. In IELTS writing and speaking tasks, using these precise collocations alongside the target vocabulary will raise your lexical resource score significantly. The exercises below are designed to help you move from recognition to active, accurate production.

Frequently Asked Questions

What is the difference between “anxiety” and “depression”?
Anxiety centres on excessive fear or worry about future events — it is characterised by a sense of dread, racing thoughts, and physical tension. Depression focuses on persistent low mood, hopelessness, and a loss of interest in activities that once brought pleasure. While they are distinct conditions, they frequently occur together and share some overlapping symptoms such as fatigue and difficulty concentrating. In everyday English, both words are sometimes used loosely to describe ordinary worry or sadness, but in a clinical or academic context they refer to specific diagnosed disorders.
What does “cognitive” mean in psychology?
Cognitive refers to mental processes involved in gaining knowledge and understanding, including thinking, reasoning, remembering, and problem-solving. In psychology, cognitive therapy focuses on identifying and changing negative thought patterns, while cognitive development describes how a person's thinking matures over time. The word derives from the Latin cognoscere, meaning “to know.” At B2–C1 level, you will encounter cognitive regularly in academic reading passages about education, behaviour, and neuroscience, often paired with nouns like cognitive bias, cognitive load, or cognitive flexibility.
How is “empathy” different from “sympathy”?
Empathy means you actively understand and share another person's feelings — you put yourself in their position and feel what they feel. Sympathy means you feel concern or sorrow for someone's situation without necessarily experiencing the same emotion yourself. Empathy is often described as “feeling with” someone, while sympathy is “feeling for” them. In professional contexts such as counselling, social work, or medicine, empathy is considered a more powerful and therapeutic quality because it fosters genuine connection and trust. IELTS and Cambridge writing tasks frequently ask candidates to discuss the value of empathy in society.
What is the difference between “conscious” and “subconscious”?
Conscious describes thoughts, feelings, and decisions that you are fully aware of — things you can reflect on and explain. The subconscious (also called the unconscious in Freudian theory) refers to mental activity that happens below the level of awareness and influences behaviour without your direct knowledge. For example, you might consciously decide to speak politely in a meeting while your subconscious discomfort with the topic causes you to avoid eye contact. In academic writing, conscious and subconscious appear frequently in discussions of decision-making, bias, and behaviour change.
Is “behaviour” spelled differently in British and American English?
Yes. Behaviour is the standard British English spelling, used in the UK, Australia, and most other English-speaking countries outside North America. American English uses behavior without the “u.” This difference follows a broader pattern: British English retains the “-our” ending in words like colour, favour, and honour, while American English drops it. For IELTS (which accepts both), Cambridge exams, and academic writing in British-oriented institutions, use behaviour. If you are writing for a US university or publication, use behavior. Consistency within a single piece of writing is the most important rule.
How do you build resilience according to psychology?
Psychology research identifies several strategies for building resilience. These include developing strong social connections, maintaining a sense of purpose, practising self-compassion, and reframing setbacks as learning opportunities rather than evidence of failure. A growth mindset — the belief that abilities can be developed through effort — is closely linked to resilience. Regular physical activity, adequate sleep, and mindfulness practices also support resilience by regulating the stress response. In IELTS Writing Task 2, resilience is a common topic in questions about mental health, education, and workplace wellbeing, so knowing how to discuss it accurately is highly valuable.
What is the difference between a “phobia” and ordinary fear?
Ordinary fear is a proportionate, protective response to genuine danger — for example, feeling afraid when crossing a busy road. A phobia is an extreme, irrational, and persistent fear of something that poses little or no actual threat. A person with a phobia experiences intense distress, physical symptoms such as a racing heart or sweating, and may go to great lengths to avoid the trigger. Common phobias include arachnophobia (spiders), claustrophobia (enclosed spaces), and social phobia (social situations). Unlike ordinary nervousness, a phobia is classified as an anxiety disorder and typically requires professional treatment such as cognitive behavioural therapy (CBT) or exposure therapy.
Why is psychology vocabulary important for IELTS?
Psychology and mental health topics appear very frequently in IELTS reading passages and Writing Task 2 questions. Common themes include the causes and effects of stress, the benefits of therapy, the relationship between exercise and mental wellbeing, and the impact of social media on self-perception. Using precise vocabulary — such as resilience, cognitive, trauma, and wellbeing — instead of vague phrases like “feeling bad” or “mental problems” demonstrates lexical range and accuracy, directly improving your score in the Lexical Resource criterion. Examiners reward candidates who can discuss abstract psychological concepts clearly and fluently.
What does “mindset” mean and how is it used in English?
Mindset refers to the established set of attitudes and beliefs that shape how a person interprets and responds to the world. The term became widely used after psychologist Carol Dweck's research distinguished between a fixed mindset (believing abilities are set at birth) and a growth mindset (believing abilities develop through effort and learning). In everyday English, mindset collocates with verbs like adopt, develop, shift, and change: “She shifted her mindset and began to see criticism as useful feedback.” It appears regularly in business English, education discourse, and self-development contexts.
What is the best way to learn and remember psychology vocabulary?
The most effective technique is to encounter each word in multiple contexts rather than simply memorising definitions. Read short articles about psychology from reliable sources such as the BBC or Psychology Today, and highlight the target words in use. Then write your own example sentence for each word, connecting it to something real in your life or a topic you care about. Use the Flash Cards above to practise retrieval — actively recalling a word from memory consolidates it far more effectively than re-reading. Finally, review words in groups of related terms: learning anxiety, phobia, trauma, and depression together helps you understand the distinctions between them.
