a report outlining why and how some research was conducted, with an analysis of the findings

Secondary appraisal

when an individual considers the available resources and their own coping strategies, to decide the best way of dealing with a stressor

Secondary data

data obtained second hand through research conducted by another person for another purpose

Self-determination

the ability to participate in decisions on matters that affect one’s life

Self-efficacy

a person’s confidence that they can complete life tasks and meet their goals

Semantic

relating to meaning

Semantic memory

the declarative memory of facts or knowledge about the world

Sensory memory

a memory store that receives and stores an unlimited amount of incoming sensory information for a brief time

Sensory neuron

a nerve cell that carries sensory signals throughout the nervous system

Sensory receptor

a sensory nerve ending that produces an afferent or sensory impulse when stimulated

Serotonin

an inhibitory neurotransmitter that also acts as a neuromodulator, influencing a variety of brain activities

Serotonin pathway

serotonin’s neuromodulatory system, which originates in the brainstem and extends to almost all areas of the cerebrum including the cerebral cortex

Shift work

work that regularly takes place outside of normal business hours, particularly at night and the very early morning; can cause a circadian rhythm sleep disorder

Stressor

any event that causes stress or is perceived as a threat and a challenge to our ability
to cope

Sung narrative

a story told through singing, music and sometimes dance

Suprachiasmatic nucleus

a master body clock in the hypothalamus that regulates body activities to a daily schedule of sleep and wakefulness

Sympathetic nervous system

a subdivision of the autonomic nervous system that increases our arousal, readying the body for a quick response

Synapse

the point of communication between two neurons or between a neuron and a target cell such as a muscle or gland

Synaptic gap

the space between the axon terminal of the presynaptic neuron and the membrane of the post-synaptic neuron

Synaptic plasticity

specific changes that occur within the synapse, between neurons

Synaptic vesicle

a membrane-bound sphere filled with neurotransmitter molecules

Synaptogenesis

the formation of new synapses that result from the process of sprouting

Systematic desensitisation

a method for treating phobias in which
the phobic stimulus is progressively introduced while the person uses relaxation techniques until their fear is replaced by a relaxation response

Systematic error

an error that causes readings to differ from the true value by a consistent amount each time a measurement is made

Table:

A way to display data and/or summary statistics clearly

Threat: The anticipated harm/loss in the future because of an event

Songline

one of many sung narratives of the landscape that weave across Country and enable every significant place in Aboriginal Dreaming to
be known

Specific environmental trigger

an object, situation or circumstance that probably caused a direct, negative traumatic experience associated with extreme fear or discomfort, which then acts as a cue for future phobic fear responses

Specific phobia

a persistent, intense, irrational fear of a specific object or event

Spinal cord

a dense bundle of nerves that carries sensory information from the body to the brain and motor information from the brain to the body

Spinal reflex

an involuntary and unconscious response to a stimulus involving the spinal cord, which occurs without input from the brain

Sprouting

the growth of axon or dendrite fibres at the synapse

Standard deviation

a statistic that shows the spread of the data around the mean

Stigma

the feeling of shame or disgrace associated with a personal characteristic that indicates you belong to a culturally devalued group in society – this can be real or imagined

Stimulus

an environmental event that triggers a response in an organism

Storage

retaining information over time

Stratified sampling

first dividing the population into subgroups, and then randomly selecting participants from each subgroup in the proportion that they appear in the population

Stress

a state of mental, emotional and physiological tension, resulting from factors that are perceived to challenge or threaten our ability to cope

Transactional model of stress and coping

a model that suggests a stress response is only elicited if an event is perceived to exceed our ability to cope and is based on our appraisal of the situation

True value

the value, or range of values, that would be found if the quantity could be measured perfectly

Ultradian rhythm

biological processes that coordinate the timing of body activities over a period of less than 24 hours

Uncertainty

a lack of exact knowledge of the value being measured

Unconditioned response (UCR)

a response that occurs automatically/ involuntarily when the unconditioned stimulus is presented

Unconditioned stimulus (UCS)

a stimulus that consistently produces a naturally occurring, automatic response

Unconscious response

any response of our nervous system that does not require awareness

Visual cortex

the primary cortical region of the brain that receives, integrates and processes visual information relayed from the retinas

Voluntary participation

an ethical guideline ensuring that each participant freely agrees to participate in a study, with no pressure or coercion

Ways of knowing

methods through which knowledge becomes apparent to us

Wellbeing

a complex combination of a person’s physical, social, emotional, mental and spiritual health that is linked to happiness and life satisfaction

Withdrawal rights

an ethical guideline that ensures the participants are free to discontinue their involvement in a study at any point during or after the conclusion of the study, without receiving any penalty

Within subjects design

an investigation design in which all participants in the sample are involved in both the experimental and control conditions

Written culture

a culture in which stories and information are shared and preserved through the processes of reading and writing

Yarn

an Indigenous system of learning that involves continually sharing stories

Zeitgeber

an environmental cue such as light, temperature and eating patterns that can synchronise the body’s circadian rhythm

Vagus nerve

a nerve that connects the brain (central nervous system) to organs within the autonomic nervous system, via nerve fibres that directly link organs such as the lungs, heart, oesophagus and intestinal tract

Validity

whether a measurement measures what it is supposed to measure

Video monitoring

a sleep study tool used to collect qualitative visual and audio information about a person’s sleep
