"differential diagnosis"

The process of distinguishing between two or more conditions that share overlapping symptoms by systematically ruling out alternatives.

"The clinician conducted a thorough differential diagnosis to distinguish between ADHD and anxiety disorder."

"psychometric validity"

The degree to which a psychological test measures the construct it purports to measure, assessed through content, criterion, and construct validity.

"The new depression scale demonstrated strong psychometric validity across diverse cultural samples."

"case conceptualisation"

An integrative framework that combines assessment data, theory, and clinical judgment to explain a client's presenting problems and guide treatment planning.

"A thorough case conceptualisation helped the therapist identify the maintaining factors of the client's panic attacks."

"structured clinical interview"

A standardised diagnostic interview that follows a predetermined set of questions to assess psychiatric conditions with high reliability.

"The SCID-5 is a widely used structured clinical interview for DSM-5 diagnoses."

"comorbidity"

The co-occurrence of two or more distinct psychological or medical disorders in the same individual at the same time.

"Comorbidity between depression and substance use disorder complicates treatment planning considerably."

"norm-referenced assessment"

A form of evaluation that compares an individual's performance to a standardisation sample representing the general population.

"Norm-referenced assessment indicated the child scored in the 3rd percentile for working memory."

"idiographic approach"

A research and clinical methodology that focuses on the unique characteristics of an individual rather than general laws applicable to all people.

"The therapist adopted an idiographic approach to understand the specific meaning the client attached to failure."

"base rate"

The prevalence of a condition or behaviour in a specified population, used to calibrate diagnostic accuracy and avoid over-diagnosis.

"Ignoring the low base rate of schizophrenia led to false positive diagnoses in the screened sample."

"working memory capacity"

The limited ability to temporarily hold and manipulate information in consciousness while engaged in other cognitive tasks.

"Working memory capacity predicts academic achievement more reliably than general intelligence alone."

"executive function"

A set of higher-order cognitive processes—including planning, cognitive flexibility, and inhibitory control—that regulate goal-directed behaviour.

"Deficits in executive function are a core feature of frontal lobe damage and several neurodevelopmental disorders."

"neuroplasticity"

The brain's ability to reorganise its structure, function, and connections in response to learning, experience, or injury throughout the lifespan.

"Neuroplasticity research has transformed rehabilitation approaches after traumatic brain injury."

"implicit memory"

A form of long-term memory that influences behaviour without conscious recollection, expressed through priming, procedural skills, and conditioned responses.

"Implicit memory for fear-conditioned stimuli persists even in patients with severe anterograde amnesia."

"attentional blink"

A temporal limitation in attention in which the second of two targets presented in rapid succession is often missed within a roughly 200–500 ms window.

"The attentional blink demonstrates the temporal bottleneck in conscious perception of sequential stimuli."

"cognitive load"

The total amount of mental effort being used in working memory at a given time, which can impair learning when it exceeds capacity.

"Poorly designed educational materials increase extraneous cognitive load and hinder comprehension."

"default mode network"

A set of interconnected brain regions that are most active during rest, self-referential thought, mind-wandering, and episodic memory retrieval.

"Disruption of the default mode network is consistently observed in depression and schizophrenia."

"inhibitory control"

The cognitive ability to suppress prepotent responses, thoughts, or distractions in favour of more adaptive goal-directed behaviour.

"Poor inhibitory control in early childhood predicts later difficulties with emotional regulation and academic performance."

"therapeutic rupture"

A deterioration in the quality of the therapeutic alliance, ranging from tension or disagreement to a significant break in the collaborative relationship.

"Recognising and repairing a therapeutic rupture can itself become a powerful corrective experience for the client."

"corrective emotional experience"

A transformative moment in therapy in which the client re-experiences a problematic relational pattern but receives a different, more constructive response.

"When the therapist responded with empathy rather than criticism, it provided a corrective emotional experience."

"mentalisation"

The capacity to understand behaviour—one's own and others'—in terms of underlying mental states such as intentions, feelings, and desires.

"Mentalisation-based therapy aims to strengthen the client's ability to reflect on their own and others' mental states."

"transference"

The unconscious redirection of feelings and expectations from past significant relationships onto the therapist or other present figures.

"The client's sudden anger toward the therapist was interpreted as transference from unresolved feelings about her father."

"countertransference"

The therapist's emotional reactions to the client, now understood as a valuable source of clinical information about the client's interpersonal patterns.

"The therapist's countertransference—a feeling of helplessness—mirrored the emotional state the client induced in others."

"therapeutic alliance"

The collaborative, trusting relationship between therapist and client, comprising agreement on goals and tasks and the quality of the emotional bond.

"Meta-analyses consistently show that therapeutic alliance is one of the strongest predictors of treatment outcome."

"exposure hierarchy"

A ranked list of feared situations or stimuli arranged from least to most anxiety-provoking, used to guide graduated exposure in cognitive-behavioural therapy.

"Together, the client and therapist constructed an exposure hierarchy for the social anxiety treatment plan."

"motivational interviewing"

A collaborative, person-centred counselling style that elicits and strengthens a client's own motivation for and commitment to behaviour change.

"Motivational interviewing helped the ambivalent client articulate his own reasons for reducing alcohol use."

"dimensional model of personality"

An approach that conceptualises personality as varying continuously along multiple trait dimensions rather than falling into discrete categorical types.

"The DSM-5 Alternative Model for Personality Disorders adopts a dimensional model, rating severity on trait spectra."

"affective dysregulation"

A pervasive difficulty managing emotional responses, characterised by heightened emotional intensity, rapid mood shifts, and prolonged emotional reactivity.

"Affective dysregulation is a core transdiagnostic feature of borderline personality disorder and bipolar spectrum conditions."

"object relations"

A psychodynamic framework focusing on internalized mental representations of self and others formed in early attachment relationships.

"Object relations theory explains how early experiences of caregivers shape adult relationship patterns and self-concept."

"dissociation"

A disruption in the normally integrated experience of consciousness, memory, identity, emotion, perception, or behaviour.

"Dissociation following trauma ranges from mild depersonalisation to distinct identity states in complex cases."

"alexithymia"

A subclinical condition characterised by difficulty identifying, describing, and distinguishing one's own feelings from bodily sensations.

"High alexithymia scores predicted poorer outcomes in emotion-focused psychotherapy."

"narcissistic injury"

A threat or damage to a person's self-esteem or self-image, often triggering shame, rage, or defensive withdrawal in individuals with narcissistic vulnerabilities.

"The critical performance review provoked a narcissistic injury that led to sudden resignation."

"paranoid ideation"

A pattern of thinking characterised by unfounded suspiciousness, mistrust, and beliefs that one is being persecuted, harmed, or conspired against.

"Subclinical paranoid ideation is more prevalent in the general population than clinical diagnoses suggest."

"anhedonia"

The diminished capacity to experience pleasure or reward from activities that were previously enjoyable, a core symptom of major depression and schizophrenia.

"Persistent anhedonia despite remission of other depressive symptoms predicted high risk of relapse."

"effect size"

A quantitative measure of the magnitude of an experimental effect or relationship, independent of sample size, used to assess practical significance.

"The intervention produced a statistically significant result, but the small effect size questioned its clinical relevance."

"meta-analysis"

A statistical technique that pools and synthesises the quantitative findings of multiple independent studies on the same topic to derive an overall estimate.

"A meta-analysis of 80 RCTs confirmed that CBT is effective for generalised anxiety disorder."

"mediator variable"

A variable that explains the mechanism through which an independent variable exerts its effect on a dependent variable.

"Cognitive restructuring was identified as a mediator variable in the relationship between therapy and symptom reduction."

"ecological validity"

The extent to which findings from a study can be generalised to real-world settings, tasks, and populations beyond the laboratory context.

"Critics questioned the ecological validity of the memory experiment because it used meaningless word lists."

"replication crisis"

The ongoing methodological problem in psychology in which many published findings fail to reproduce when independent researchers repeat the studies.

"The replication crisis prompted widespread adoption of pre-registration and open-data practices."

"structural equation modelling"

A multivariate statistical technique that tests complex relationships among observed and latent variables simultaneously, combining path analysis and factor analysis.

"Structural equation modelling confirmed that attachment anxiety mediated the effect of childhood neglect on adult depression."

"double-blind procedure"

An experimental design in which neither the participants nor the researchers assessing outcomes know who received the treatment or the control condition.

"The double-blind procedure ensured that therapist expectations did not bias outcome ratings in the clinical trial."

"random assignment"

The process of allocating participants to experimental conditions purely by chance, which equates groups on known and unknown confounding variables.

"Without random assignment, the observed benefits of the new therapy could be explained by group differences at baseline."

"disorganised attachment"

An insecure attachment pattern in which children display contradictory or disoriented behaviour toward caregivers, associated with unresolved trauma in parents.

"Disorganised attachment in infancy predicts heightened risk for dissociation and personality difficulties in adulthood."

"theory of mind"

The ability to attribute independent mental states—beliefs, desires, intentions—to oneself and others, underpinning social understanding and empathy.

"Theory of mind deficits are a hallmark feature of autism spectrum disorder and are linked to social difficulties."

"epigenetics"

The study of heritable changes in gene expression that do not alter DNA sequence but are influenced by environmental experiences, including early adversity.

"Epigenetics research shows that childhood maltreatment can alter stress-response gene expression across generations."

"stereotype threat"

The risk of confirming a negative stereotype about one's social group, which can impair performance through anxiety and cognitive interference.

"Stereotype threat reduced maths performance in women who were reminded of the gender gap before the test."

"prosocial behaviour"

Voluntary actions intended to benefit others or society, including helping, sharing, donating, cooperating, and comforting.

"Prosocial behaviour in toddlers emerges before language, suggesting an early-developing altruistic motivation."

"social comparison theory"

Festinger's theory that people evaluate their opinions and abilities by comparing themselves to others, especially when objective standards are unavailable.

"Social comparison theory explains why social media use often correlates with decreased self-esteem."

"sensitive period"

A developmental window during which an organism is especially receptive to particular environmental inputs, and during which certain skills or capacities are optimally acquired.

"The sensitive period for language acquisition extends roughly from birth through early adolescence."

"scaffolding"

Vygotsky's concept for the temporary support provided by a more skilled person to help a learner accomplish tasks within their zone of proximal development.

"Effective scaffolding involves gradually withdrawing support as the child demonstrates increasing competence."
