Dement and Kleitman

Who were the authors of the study and in which year was it conducted?

• Dement and Kleitman (1955)

• Dement and Kleitman (1957)

• Dement and Freud (1957)

• Freud and Kleitman (1955)

Which of the following is a complexity in studying sleeping and dreaming?

• Easily replicable experiments

• Subjective experiences and interpretations

• Objective and quantifiable measurements

• Controlled and predictable dream patterns

In what way were Dement/Kleitman's EEG machines different from modern EEGs?

• They were wireless

• They had higher resolution

• They were portable

• They had fewer electrodes

The EOG (electrooculogram) was used to measure:

• Heart rate

• Eye movements

• Brainwave patterns

• Muscle activity

Aim 1 of the study was to:

• Explore dream content through interviews and questionnaires

• Monitor brainwave patterns during REM and non-REM sleep

• Analyze eye movements during different stages of sleep

• Investigate the effect of sleep duration on dream recall

What research method was used for approach 1?

• Correlational

• Experimental

• Observational

• Case study

Dream recall was higher in:

• REM sleep

• n-REM sleep

• Both REM and n-REM sleep equally

• Neither REM nor n-REM sleep

The study concluded that:

• Dreaming primarily occurs in n-REM sleep

• There is a strong correlation between REM sleep and dreaming

• Dreaming occurs during wakefulness

• Dreaming is unrelated to sleep stages

What was the primary method used to collect data in the study?

• Interviews

• Questionnaires

• EOG (electrooculogram)

• EEG (electroencephalogram)

How did the research method of approach 1 differ from traditional methods?

• It was observational

• It was experimental

• It was correlational

• It was a case study
