- Operant conditioning
- Related: Reinforcement, Punishment, Extinction
A learning process in which the likelihood of a behaviour changes because of the consequences that follow it, such as rewards or punishments, rather than through pairing with a prior stimulus.
- Classical conditioning
- Related: Unconditioned stimulus, Extinction, Generalisation
Learning in which a neutral stimulus comes to trigger a response after being repeatedly paired with a stimulus that already produces that response, as in Pavlov's salivating dogs.
- Unconditioned stimulus
- Related: Classical conditioning, Conditioned stimulus
In classical conditioning, a stimulus that naturally and automatically produces a response without any prior learning, such as food causing salivation in a hungry animal.
- Conditioned stimulus
- Related: Classical conditioning, Unconditioned stimulus
A previously neutral stimulus that, after being paired with an unconditioned stimulus, acquires the power to elicit a learned response on its own.
- Reinforcement
- Related: Operant conditioning, Punishment, Schedules of reinforcement
Any consequence that increases the frequency or strength of the behaviour it follows. It may be positive, adding something pleasant, or negative, removing something unpleasant.
- Punishment
- Related: Reinforcement, Operant conditioning
A consequence that weakens or reduces the frequency of the behaviour it follows, either by adding an unpleasant event or by removing something desirable.
- Extinction
- Related: Classical conditioning, Spontaneous recovery, Reinforcement
The gradual weakening and disappearance of a learned response when the reinforcement or conditioned pairing that maintained it is withdrawn.
- Spontaneous recovery
- Related: Extinction, Classical conditioning
The reappearance of a previously extinguished conditioned response after a rest period, showing that extinction suppresses learning rather than erasing it.
- Generalisation
- Related: Discrimination, Classical conditioning
Responding in the same way to stimuli that resemble the original conditioned stimulus, so that learning spreads beyond the exact situation in which it was acquired.
- Schedules of reinforcement
- Related: Reinforcement, Operant conditioning
Rules determining how often and when a response is reinforced, such as fixed-ratio or variable-interval patterns, which strongly affect how quickly and persistently behaviour is learned.
- Working memory
- Related: Short-term memory, Long-term memory, Encoding
A limited-capacity system that temporarily holds and manipulates information during tasks such as reasoning, comprehension and problem solving.
- Short-term memory
- Related: Working memory, Chunking, Encoding
The store that holds a small amount of information for roughly twenty to thirty seconds without rehearsal, typically around seven items.
- Long-term memory
- Related: Working memory, Retrieval, Encoding
The relatively permanent store of knowledge and skills, with effectively unlimited capacity, from which information can be retrieved after long delays.
- Encoding
- Related: Retrieval, Working memory, Chunking
The process of transforming sensory information into a form that can be stored in memory, influenced by attention, depth of processing and prior knowledge.
- Retrieval
- Related: Encoding, Long-term memory
The process of locating and bringing stored information back into conscious awareness, which can be helped by cues and context matching.
- Chunking
- Related: Short-term memory, Encoding
A memory strategy that groups separate items into larger meaningful units, allowing more information to be held within a limited capacity store.
- Schema
- Related: Assimilation, Accommodation, Encoding
A mental framework built from past experience that organises knowledge and guides how new information is interpreted, stored and recalled.
- Assimilation
- Related: Accommodation, Schema, Equilibration
In Piaget's theory, fitting new information into an existing mental framework without changing that framework.
- Accommodation
- Related: Assimilation, Schema, Equilibration
In Piaget's theory, altering an existing mental framework, or creating a new one, because new information cannot be fitted into what is already known.
- Object permanence
- Related: Sensorimotor stage, Conservation
The understanding that objects continue to exist even when they are out of sight, typically developing towards the end of infancy.
- Conservation
- Related: Object permanence, Egocentrism, Concrete operational stage
The understanding that quantity, mass or volume stays the same despite changes in appearance or arrangement, a skill usually acquired in middle childhood.
- Egocentrism
- Related: Conservation, Theory of mind
Difficulty in taking another person's viewpoint or recognising that others may hold beliefs and perceptions different from one's own.
- Attachment
- Related: Separation anxiety, Internal working model
A strong, enduring emotional bond between an infant and a caregiver, shown in seeking proximity, distress at separation and pleasure at reunion.
- Internal working model
- Related: Attachment, Separation anxiety
A mental representation of self and others built from early caregiving experiences, which shapes expectations and behaviour in later relationships.
- Separation anxiety
- Related: Attachment, Stranger anxiety
Distress shown by an infant or young child when separated from a familiar caregiver, peaking in the second half of the first year.
- Stranger anxiety
- Related: Separation anxiety, Attachment
Wariness or distress shown by infants towards unfamiliar people, typically emerging around six to nine months of age.
- Conformity
- Related: Obedience, Normative social influence, Compliance
Changing one's behaviour or expressed beliefs to match those of a group, often because of real or imagined pressure from others.
- Obedience
- Related: Conformity, Compliance, Agentic state
Following a direct order or instruction from a person in authority, even when the requested action conflicts with personal judgement.
- Compliance
- Related: Conformity, Obedience
Agreeing to a request without necessarily changing private beliefs, often through techniques such as reciprocity or the foot-in-the-door approach.
- Normative social influence
- Related: Informational social influence, Conformity
Conformity driven by the desire to be liked and accepted by a group, rather than by a belief that the group is correct.
- Informational social influence
- Related: Normative social influence, Conformity
Conformity driven by the belief that others possess accurate information, so their judgements are used as a guide to reality.
- Bystander effect
- Related: Diffusion of responsibility, Prosocial behaviour
The finding that people are less likely to help in an emergency when others are present, partly because responsibility is shared among witnesses.
- Diffusion of responsibility
- Related: Bystander effect, Prosocial behaviour
A reduction in personal responsibility felt by each member of a group, so individuals are less likely to act than if they were alone.
- Prosocial behaviour
- Related: Bystander effect, Diffusion of responsibility
Voluntary actions intended to benefit other people, such as helping, sharing, comforting or cooperating, without obvious personal reward.
- Personality
- Related: Trait theory, Trait
The relatively stable pattern of thoughts, feelings and behaviours that distinguishes one person from another across situations and over time.
- Trait
- Related: Personality, Trait theory
A relatively enduring characteristic or disposition that predisposes a person to behave in consistent ways across a range of situations.
- Trait theory
- Related: Trait, Personality
An approach to personality that describes individuals in terms of stable dimensions of difference, such as extraversion or neuroticism, rather than unconscious conflicts.
- Unconscious
- Related: Defence mechanism, Psychoanalysis
In psychodynamic theory, the part of mental life containing thoughts, wishes and memories outside awareness that nonetheless influence behaviour and feelings.
- Defence mechanism
- Related: Unconscious, Psychoanalysis
An unconscious mental strategy used to protect the self from anxiety, for example by denying, projecting or rationalising uncomfortable thoughts and impulses.
- Locus of control
- Related: Personality, Trait theory
A person's general belief about whether outcomes depend on their own actions, an internal locus, or on outside forces such as luck or other people.
