Detailed explanation-1: -Ecological validity A limitation of Canli et al.is that it has low ecological validity. This is because participants were asked to lie in a fMRI scanner which reviewing images and they had to indicate their emotional arousal by pressing a button.
Detailed explanation-2: -weaknesses: it fails to account for the fact that some memories may be remembered as strongly as others even if lesser in emotional impact. strengths: it explains the impact of natural human inheritance on human emotions.
Detailed explanation-3: -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-4: -Canli found an association between individual experiences of emotional intensity for stimuli with amygdala activation and memory. The more emotionally intense an image is, the more likely it will be remembered. This provides evidence to explain why people remember emotionally intense experiences well.
