Chapter 8 KEY TERMS Flashcards
Advanced sleep phase disorder (ASPD)
A circadian rhythm sleep disorder characterised by an advance in the timing of sleep onset and awakening compared to the timing that is desired
Affective functioning
the attitude or emotion elicited by a stimulus (such as sleep deprivation)
Behavioural functioning
The effects on behaviour elicited by a stimulus (such as sleep deprivation)
Blood-alcohol concentration (BAC)
A measure of alcohol in the body expressed as grams of alcohol/100 mL of blood
Blue light
Colour in the visible light spectrum that can be seen by human eyes
E.g
- sunlight
- phone screens
- LED lights ect
Bright light therapy
A technique for treating circadian rhythm sleep disorders by using timed exposure of the eyes to light in order to shift an individuals sleep-wake cycle to a desired, more appropriate or conventional schedual
Circadian rhythm sleep disorder
A sleep disorder involving sleep disturbance that is primarily due to a mismatch between an individual’s sleep-wake pattern and the pattern that is desired or required
Cognitive functioning
The effects on cognitive processes
elicited by a stimulus (such as sleep deprivation)
Daylight
Natural light from the sun
Delayed sleep phase syndrome (DSPS)
A cricadian rhythm sleep disorder characterised by a delay in the timing of sleep onset and awakening compared with the timing that is desired
Eating and drinking pattern
What a person eats or drinks and when
Emotional reactivity
The tendency to experience frequent and intense emotional arousal
Entrainment
Process of adjusting or resetting a biological rhythm to align with external cues or an environmental cycle
Fixed shift work schedule
When employees work the same shift on a regular, ongoing basis
Microsleep
A very short period (e.g. a few seconds) of involuntary sleep
Partial sleep deprivation
Involves having less sleep (either
quantity or quality) than what is normally required
Rotating shift work schedule
When employees change shifts
every so often to work a mix of day and/or afternoon and/or night shifts
Shift work disorder
A circadian rhythm sleep disorder due to work shifts being regularly scheduled during the usual sleep period; work shifts overlap with all or part of the sleep period, requiring adjustment of sleep and wake times to the work times;
Sleep debt
The accumulated amount of sleep loss due to insufficient sleep
Sleep deprivation
Inadequate quantity or quality of sleep
Sleep disorder
Any sleep disturbance that is persistent and regularly disrupts sleep, causing distress or impairment in important areas of everyday life during normal waking hours
Sleep disturbance
Any sleep-related problem that disrupts an individual’s normal sleep–wake cycle
Sleep hygiene
Practices that tend to improve and maintain good sleep and full daytime alertness
Sleep inertia
A temporary period of reduced alertness and performance impairment that occurs immediately after awakening, especially after a poor night’s sleep and if abruptly awakened
Sleep quality
How well a person feels they have slept
Sleep quantity
The amount of sleep a person gets
Sleep-wake cycle
a change (advancement or delay) in the timing of the major sleep episode
Temperature
the degree or intensity of heat present in a person, substance or object
Total sleep deprivation
not having any sleep at all over a short-term or long-term period
Zeitgeber
An environmental time cue
