Psychology glossary
The terms you meet in a diagnosis, an article or a therapist's description — explained briefly, without jargon, and with a note on what they are most often confused with.
- Alexithymia
- Difficulty identifying and naming your own emotions. Not their absence — you feel them in the body, but lack the word that describes them.
- Anhedonia
- The loss of the ability to feel pleasure from things that used to produce it. One of the two core symptoms of depression.
- Anticipatory anxietypre-event anxiety
- Anxiety produced by waiting for an event rather than by the event itself — usually longer and more intense than what follows.
- Anxious attachmentpreoccupied attachment, anxious-ambivalent
- A relational pattern in which closeness is intensely wanted and simultaneously felt as unsafe — hence the constant need for reassurance and extreme sensitivity to signs of distance.
- Assertivenessassertive communication
- Saying what you need directly, without erasing yourself and without trampling the other person — the third option between submission and aggression.
- Avoidant attachmentdismissive attachment, avoidant-dismissive
- A pattern in which independence is overvalued and closeness feels like a threat to autonomy — usually not from an absence of needs, but from having learned that needs are not received.
- Burnoutoccupational burnout, exhaustion syndrome
- A three-part syndrome — exhaustion, cynical detachment and a drop in the sense of efficacy — classified by the WHO as an occupational phenomenon, not a disease.
- Catastrophising
- The automatic jump to the worst possible outcome, treated as though it were the most likely one. One of the core cognitive distortions in anxiety.
- Codependencyrelational dependency
- A pattern in which self-worth and a sense of purpose come to depend on caring for someone or keeping them stable — usually at the cost of your own needs.
- Cognitive distortions
- Systematically inaccurate thinking patterns that occur in everyone but multiply in anxiety and depression. Not errors of logic — shortcuts that misfire.
- Complex traumacomplex PTSD, C-PTSD
- The aftermath of repeated, prolonged exposure to traumatic events, usually relational and inescapable — recognised as a separate diagnosis in ICD-11.
- Complicated griefprolonged grief disorder
- Grief that stays at its initial intensity long after the loss and blocks functioning — not grief that is “too much”, but grief that does not move at all.
- Compulsionsrituals, safety behaviours
- Actions or mental rituals repeated to reduce the anxiety a thought produces — effective in the short term, and precisely why the problem persists in the long term.
- Defence mechanismspsychological defences
- Largely unconscious strategies by which the mind lowers the anxiety produced by something hard to accept — useful in small doses, costly when they become the default mode.
- Dissociationdepersonalisation, derealisation
- A disconnection from your own thoughts, feelings, body or surroundings — usually a protective mechanism, not a sign of madness.
- Emotional neglectchildhood emotional neglect
- Not what happened, but what did not — the absence of response to a child's emotional needs, in a home that may otherwise have been fine.
- Emotional regulationself-regulation, affect regulation
- The ability to influence which emotion you have, how intensely you feel it and how long it lasts — without suppressing it and without being swept away by it.
- Emotional validation
- Acknowledging that someone's emotion makes sense in their context — without agreeing with their conclusions and without trying to fix it.
- Experiential avoidance
- The effort not to feel something unpleasant — and the common mechanism sitting under anxiety, addiction, procrastination and emotional eating.
- Flashbackreliving
- Re-experiencing a past event as though it were happening now — not a memory you recall, but one you live through again.
- Gaslightingreality manipulation
- A pattern in which someone makes you systematically doubt your own memory, perception or judgement — until you no longer trust what you saw with your own eyes.
- Hypervigilance
- A state of permanent alertness in which the nervous system continuously scans the environment for danger — even when there is none.
- Impostor syndromeimpostor phenomenon
- The persistent belief that your success is undeserved and that someone will soon notice — resistant to evidence, because each piece of evidence is reread as luck.
- Insightrealisation, awareness
- The moment you understand why you do something — necessary in many cases, sufficient almost never.
- Intrusive thoughtsunwanted thoughts, obsessions
- Thoughts or images that arrive uninvited, often shocking or contrary to your values — universal as a phenomenon, problematic only in how hard you fight them.
- Maladaptive perfectionismneurotic perfectionism, rigid standards
- Not high standards themselves, but the inability to be satisfied when they are met — plus the belief that your worth depends on meeting them.
- Mindfulnesspresent-moment awareness
- Attention deliberately directed at present experience, without judging it — a trainable skill, not a state of calm.
- Neuroplasticitybrain plasticity
- The brain's capacity to change its structure and connections in response to experience — the biological basis for therapy being able to work at all.
- Panic attackpanic episode, anxiety attack
- A sudden surge of intense fear with strong physical symptoms, peaking in about ten minutes and passing on its own — though while it lasts it feels like it never will.
- Personal boundariesboundaries, healthy limits
- The line between what is your responsibility and what is someone else's — expressed through what you accept, what you decline and what you do when someone crosses it.
- Projectionpsychological projection
- Attributing to someone else a feeling or trait you cannot acknowledge in yourself — which then becomes, suddenly, highly visible in them.
- Resistance in therapyambivalence about change
- Everything that slows the therapeutic process — historically read as the patient's opposition, today understood more as a signal about pace, safety or the fit of the method.
- Ruminationcircular thinking
- Going over the same thoughts about a problem repeatedly without reaching a solution. The strongest maintaining factor in depression.
- Self-esteemself-worth, self-regard
- The overall judgement you make of your own worth — less stable and less useful than commonly assumed, which is why recent research has shifted toward self-compassion.
- Self-sabotageself-handicapping
- Behaviours that wreck something you want — usually not from lack of motivation, but because failing with an excuse hurts less than failing without one.
- Somatisation
- Psychological distress expressed through real physical symptoms — pain, tension, digestive trouble — with no medical cause that fully explains them.
- Toxic shamechronic shame, internalised shame
- The belief that the flaw is not in what you did but in what you are — which is why it is not repaired by apology and not extinguished by achievement.
- Transferencetherapeutic transference
- The replaying, in the relationship with the therapist, of an old relational pattern — disruptive if ignored, and one of the most useful sources of information if noticed.
- Triggeractivating cue
- A cue that reactivates a reaction learned from an earlier experience — a smell, a tone of voice, a time of day — at an intensity out of proportion to the present situation.
- Window of toleranceoptimal arousal zone
- The band of arousal in which you can feel and think at the same time — below it you numb out, above it you flood, and learning happens in neither.
These definitions are informational. They do not replace an assessment by a professional and are not enough for self-diagnosis.
