Random Sampling

is where everyone in the population has an equal chance of being selected to participate in the study.

Extraneous Variables

are any variable other than the IV that may impact on the DV and hence the results of the study.

Conclusions Structure

Based on this study, for this sample it can be concluded that

Zeitgebers

refers to environmental and external cues that help synchronise our circadian rhythms.

Partial Sleep Deprivation

is when someone does not receive adequate quality or quantity of sleep required for optimal daytime functioning

Circadian Phase Disorders

refers to disturbances to typical sleeping and waking patterns that interfere with the regulation of the circadian rhythm of sleep.

Extended Response Outline Para 1

1. define circadian sleep phase disorders

2. shift workers are at a greater risk because of higher melatonin levels meaning they are sleepier at work

3. shift workers are at a greater risk as they suffer from partial sleep deprivation

4. effects of sleep deprivation leading to more workplace accidents

Extended Response Outline Para 2

1. struggle to get optimal hours of sleep because of light outside and noises

2. control this by limiting noise and light and creating a comfortable sleeping environment, as well as warm body and cold room.

Extended Response Outline Para 3

1. define zeitgebers

2. artificial use of light to help with accidents through BLT before work and to help with hours of sleep by limiting blue lights.

3. natural use of light to help with accidents through increased exposure to daylight to increase melatonin and to help with hours of sleep by limiting daylight before sleeping

Shift Work

leads to poor quality and quantity of sleep
