29 of 70
each stage characterised by diff level of?

30 of 70
what are stages 1 and 2?
light sleep
31 of 70
where person can be easily?
woken
32 of 70

EVALUATION
DFGDF
44 of 70
:) evolutionary basis of menstrual cycle
dgdf
45 of 70
for ancestors it may have been advantageous for females to menstruate together why?
fall pregnant at same time
46 of 70
meaning what for new borns?
could be caredfor collectively
47 of 70
increasing chances of?
offspring survival
48 of 70
however wat did schank suggest about too many females cycling together in social grp?
create competition for highest quality males
49 of 70
from this pov which would seem most adaptive evolutionary strategy?
avoidance of synchrony
50 of 70
:( methodological limitations in sychn stydies
gdf
51 of 70
commentators argue what may act as confounding variables?
stress / diet changes / exercise etc
52 of 70
meaning any supposed pattern of synch is no more than would have been expected by?
chance
53 of 70
what's difficult with sample?
small size
54 of 70
and relies on women doing what?
self-reporting
55 of 70
other studies failed to do what?
find any evidence of menstrual synchrony
56 of 70
:) evidence supporting idea of sleep stages
dfgdf
57 of 70
dement and kleitman monitored sleep patterns where?
sleep lab
58 of 70
brainwave activity recorded on?
EEG
59 of 70
and rsrchrs controlled for effects of?
caffeine / alcohol
60 of 70
REM in sleep highly correlated with?
dreaming
61 of 70
brain activity varied accoriding to what about dreams?
vividness
62 of 70
and pps woken in dreaming reported?
v accurate recall of dreams
63 of 70
what have replications shown?
similar findings
64 of 70
though waht ahs been criticised methodologically?
small sample size
65 of 70
EVAL EXTRA

66 of 70
:( animal studies
dfgdf
67 of 70
much knowledge of what derived from animals?
effect of phermones on behaviour
68 of 70
for instance why do sea urchins release pheromones into surrounding water?
so other urchins eject sex cells simultaneously
69 of 70
but in contrast evidence for effects in humna behaviour remains?
specilative and inconclusive
