GLOSSARY Flashcards
Accuracy
How close a measure relates to the ‘true’ value of the quantity being measured.
Acronym
A pronounceable word formed from the first letters of a group of words.
Acrostic
In relation to a mnemonic, making verbal associations for items to be remembered by constructing a sentence, phrase or other composition using the first letters of the information to be remembered.
Activity scheduling
See behaviour activation.
Acute stress
Stress that lasts for a relatively short time.
Adaptive behaviour
Any behaviour that enables the individual to adjust to the environment appropriately and effectively; compare with maladaptive behaviour.
Adrenaline
A hormone secreted during stress; also called epinephrine.
Advanced Sleep Phase Disorder
A circadian rhythm sleep disorder characterised by a shift of the major sleep episode to an earlier time compared to desired or conventional sleep times, resulting in sleep onset and awakening much earlier than desired and excessive sleepiness; see also circadian rhythm sleep disorder; compare with Delayed Sleep Phase Syndrome.
Afferent pathway
A neural pathway that carries information towards the brain or spinal cord (e.g. sensory information); compare with efferent pathway.
Agonist
A chemical agent (e.g. drug) that stimulates neurotransmitter activity; compare with antagonist.
Aim
A statement outlining the purpose of the investigation.
Alarm reaction
The first stage of the General Adaptation Syndrome in which the body goes into a temporary state of shock, then rebounds (counter shock), following initial awareness of a stressor.
Alpha brain wave pattern
Associated with a relaxed, calm, internally focussed wakeful state of consciousness, especially if eyes are closed.
Altered state of consciousness
Any state of consciousness that is distinctly different from normal waking consciousness or any waking state in terms of level of awareness and experience; compare with normal waking consciousness.
Alzheimer’s disease
A neurodegenerative disorder characterised by gradual widespread degeneration of brain neurons, progressively causing memory decline, deterioration of cognitive and social skills, and personality changes.
Amygdala
A small structure in the medial temporal lobe, deep within the brain and part of the limbic system; involved in emotional reactions (particularly fear and anger) and formation of a wide variety of emotional memories.
Anecdote
An informal verbal report of an event that has been casually observed.
Antagonist
A chemical agent (e.g. drug) that inhibits neurotransmitter activity; compare with agonist.
Antecedent stimulus
An object or event that precedes a specific behaviour and signals the probable consequence for the behaviour and therefore influences the occurrence of the behaviour.
Anticipatory anxiety
In relation to specific phobia, worry or apprehension about the possibility of being exposed to a phobic stimulus in the future.
Anxiety
A state of arousal involving unpleasant feelings of apprehension or uneasiness that something is wrong or something unpleasant is about to happen.
Aphantasia
Absence of visual imagery.
Appraisal
An relation to the Lazarus and Folkman model, the cognitive evaluation of the nature and significance of a stressor; see primary appraisal and secondary appraisal.
Approach coping strategy
An effort to cope with stress by confronting the stressor and dealing directly with it and its effects; compare with avoidance coping strategy.
Atkinson–Shiffrin multi-store model
A representation and explanation of memory as consisting of three separate stores called sensory memory, short-term memory and long-term memory, differing in function, capacity and duration.
Attention
The process of focusing on specific stimuli or aspects of the sensory environment whilst ignoring and therefore excluding others; in observational learning, the first step in the process which involves watching a model’s behaviour and its consequences.
Autobiographical memory
A person’s memory for episodes or experiences that occurred in their own life; compare with episodic memory.
Autonomic nervous system
A sub-division of the peripheral nervous system that connects the central nervous system to the body’s internal organs and glands, providing feedback to the brain about their activities.
Avoidance behaviour
In relation to specific phobia, actions that help avert any contact, exposure or engagement with a phobic stimulus.
Avoidance coping strategy
An effort to cope with stress by evading the stressor and dealing indirectly with it and its effects; compare with approach coping strategy.
Basal ganglia
A group of structures (neuron cell bodies called nuclei) deep within the brain, involved in the generation of voluntary movements and long-term implicit memories involving motor skills.
Behaviour
Any action made by a living person (or animal) that can be observed or measured.
Behaviour activation
A CBT technique to help an individual identify and schedule activities that promote enjoyment or reduce stress; also called activity scheduling.
Behaviourist approach to learning
Emphasises the study of observable behaviour alone to understand and explain learning, without regard to underlying mental processes; see classical conditioning and operant conditioning.
Behavioural model
Based on the theory that individuals’ actions and behaviours are learned.
Beneficence
In relation to research ethics, the commitment to maximising benefits and minimising the risks and harms involved in taking a particular position or course of action.
Benzodiazepines
A group of drugs that work on the central nervous system, acting selectively on GABA receptors in the brain to increase GABA’s inhibitory effects and make postsynaptic neurons resistant to excitation; commonly called sedatives or mild tranquilisers.
Beta brain wave pattern
Associated with alertness and intensive mental activity during normal waking consciousness; also present during REM sleep dreams.
Between groups
See between subjects.
Between subjects
An experimental design in which each participant is assigned to only one group or condition and provides only one score for data analysis; also called independent groups and between groups.
Biased sample
A research sample that does not adequately represent the key characteristics of its population.
Biological clock
Innate timing that regulates one or more biological rhythms; see also suprachiasmatic nucleus.
