Canli et al. what is the IV and DV
Iv- Intensity of emotional arousal
DV- Level of activation on amegdala
Canli et al. Help validity
standardized no demand characteristics removes extraneous variables.no confounding variables
Canli et al. Conclusions
1.Level of arousal effects strength of memory trace.
2.correlation showing association between emotional impact on participation and subsecuqent memory for items.
Canli et al. How is it scientific
FMRI Produces quantitative and qualitative data
Canli et al. what experimental group
Repeated measure design
Canli et al. One criticism
HArd to generalize bc small sample group
Canli et al. Sample group
7 right handed healthy females
Canli et al. Concerns about ecological validity
Lab not normal environment
Dement And Keitman Iv and DV?
IV-whether patient is woken in REM or nREM
DV-weather they dream if so in detail
Dement And Keitman helps validity
Definition of dream operationalized.
Dement And Keitman Conclusion
1.Dream during REM not REM Participants can
judge length of dream.
2.Dreams more likely occur during end of night when
REM is stronger
Dement And Keitman how is it scientific?
Collected both quantitative and qualitative data to prove or disprove hypothesis
Dement And Keitman experimental design
Repeated measure design
Dement And Keitman One critisim
Small not diverse sample group
Dement And Keitman sample group
7 male 2 female adults 5 in detail 4 for confirmation
Dement And Keitman Concerns about ecological validity
non natural environment PPl no sleep in lab.
Schachter and singer IV and DV
IV- weather informed or misinformed about injections.
DV- Observational data recorded by one way mirror by what extent participants were angry to euphoria
Schachter and singer Helps validity?
Double blind technique person watching over double sided mirror.
Schachter and singer Conclusions
1.we label our arousal according to the cognitions we have available.
2. if a
person experiences a state of arousal for which they have
no immediate explanation, they will label this state and
describe their feelings in terms of the cognitions available
to them at the time.
3. helps us understand how
people use different environmental cues to help them
interpret their physiological state.
Schachter and singer How was it scientific
Administered by doctors quantitative data collected through observation which allows hypothesis to be tested.
Schachter and singer experimental design
Independent group design
Schachter and singer One criticism
Sample distorts validity.
Schachter and singer sample group
185 male intro to psych @ university of minnesota
Schachter and singer concerns about validity.
Only carried out with college aged males.
