Term
| Qu: State one of the hypothesis in your chosen study(Dement and Klietman). |
|
Definition
- There is a significant accosiation between REM sleep nad reported Dreaming.
- There is a significant correlation between the estimate of time spent dreaming and the measurement of REM sleep.
- There s a significant association between the pattern of eye movement and reported dream content

|
Term
| Qu: State the sample used in your chosen study and suggest one weakness of it. |
|
Definition
- Dement and Klietman: 9 adults (7 male, 2 female), 5 of whom were studied intensively, all from USA.
- Weakness: Sample size, drawn from America, therefore not generalised.
- Drawn from America- means it is ethnocentric (restricted to the group the person belongs to)
|
|
|
Term
| Qu: Outline two of the quantitative measures recorded in this study. |
|
Definition
- Number of dreams recalled after awakenings in REM and NREM sleep.
- Accuracy of dream length when awakened after 5 or 15 minutes of REM sleep.
|
|
|
Term
| Qu: With references to your study (Dement and Klietman) suggest one strength and one weakness of quantitative data. |
|
Definition
- General strengths of quantitative data eg allows identification of patterns of behaviour, can calculate averages, can show disperion, results, easy to analyse, allows comparisons between groups/individuals; supported wuth evidence from the chosen study.
- General weaknesses of quantitative data eg gives no explanation for why the behaviour occurred, looses 'richness', is fairly superficial; supported by evidence from chosen study.
|
|
|
Term
| Qu: Outline the results of your chosen study. |
|
Definition
- More dreams were recalled from REM than NREM sleep (152:11)
- There wre significantly more correct estimates of length of REM than incorrect estimates.
- There was a strong association between patterns of REMs and the content of dreams.
|
|
|
Term
| Qu: Suggest one change to this study and explain how this might effect the results. (8) |
|
Definition
- One way you could improve this study is to increase the sample size. The sample in this study is androcentric and ethnocentric. So they could improve the study by using a even amout out males and females eg 25 male and 25 females. This would make the sample more representitive to the population and easly repeatable if repeated due to a larger sample
