Detailed explanation-1: -RESEARCH METHOD AND DESIGN OF CANLI ET AL The IV was the level of emotional arousal perceived by the participant ( on a four-point scale from 0-3). The DVs of the study were the memory/recollection of the scene viewed and the second was the fMRI measure of amygdala activation.
Detailed explanation-2: -Canli et al (1999) found strong amygdala activation to resulted in improved memorization for the causing stimuli. He wanted to replicate his study with repeated measures design rather than independent to make sure that the initial results were not due to chance.
Detailed explanation-3: -He wanted to replicate the study with repeated measures design rather than independent to make sure that the initial results were not due to chance. A laboratory experiment was conducted. The repeated measures design was implemented as participants were unexpectedly asked to repeat the procedure after 3 weeks.
Detailed explanation-4: -High internal validity One strength of the study Canli et al.is that the study has high internal validity. This is because there was a standardized procedure and high levels of control, for example there was a bite bar (with dental impression) for each participant which was used to minimise head movement.
