State an aim of the Canli et al. Study To show that emotive images will be remembered better than those that have little emotional impact on an individual. Evaluate Canli et al. usefulness in psychology May be useful to advertising companies; they can use emotionally intense information that is likely to be recognized later on with the use of emotionally intense imagery. The brain as well was studied in an active state. But the study does serve to be reductionist since it only focuses on one portion of the brain (amygdala) and the study doesn't enable insight to the brains function in a natural environment.

Repeated measures; Participants were first viewed 96 images while attached to the FMRI scanner. 3 weeks later the participants were tested in an unexpected recognition test viewing the 96 previous images and 48 new ones (foils). Participants were asked if they had seen each scene before with certainty or not. How was Canli et al. sample gathered? Volunteer Refer to the nature vs. nurture debate in the Canli et al. study Some argue that the findings because they are emotions linked to brain function that the study supports a link to nature but on the flip side experiences were not taken into account in the study so it could be nurture causing the results. A strength of the biological approach used in Canli et al. With the use of sophisticated machinery such as the FMRI scanner it allowed researchers to focus on the amygdala to study the relationship between emotional experience and long term memory. Prior to this technological advance the brain could not be actively studied unless subject was dead. A weakness of the biological approach used in Canli et al. Scientific machinery requires tests to be down in a lab which results in low ecological validity. The participants as well had to lie very still in order for the machine to gain accurate results. Using these machines remains to be very costly as well as time consuming. Resulting in the use of a very small group of participants being used making the findings not generalizable. Who were the participants in Canli et al. 10 right handed healthy females State an aim of the Dement & Kleitman study Does dream recall differ between eye movement {REM} and non {REM} sleep Evaluate Dement & Kleitman usefulness in psychology Objective data was gathered from an EEG (Electroencephalograph) and it furthers our understanding of how the brain works giving first major insight into REM sleep and its direct link to dreaming. But, the sample size is small and issues with the gender of the sample could arise, so the findings are not generalizable. Due to low ecological validity the findings are not useful in describing real sleeping behavior. How many participants were in Dement & Kleitman's study and how was this sample gathered? 7 males and 2 females, volunteer sample (American) Explain the use of psychometrics in Dement & Kleitman The use of the EEG allowed for scientific measurements in terms of reliable wake-ups and researchers had insight into what stage of sleep the participants were in when they awoke. A strength of the biological approach in Dement & Kleitman Use of sophisticated machinery like the EEG used to measure brain waves in participants to show valid and reliable data that gave precise and objective determination that they were waking the participants at the correct sleep stage. This also resulted in practical applications. This study reveals that we all go through sleep cycles each night and that dreaming occurs during the time in which our eyes are moving during REM sleep. A weakness of the biological approach in Dement & Kleitman Participants dreams or sleep cycles may have been affected due to low ecological validity. They had to arrive to the lab before bedtime and sleep with machinery attached to them which is unlike a normal environment. The use of the EEG as well is very costly and time consuming which could impact the sample size of the participants. What did the researchers do to increase validity of the findings in the study Dement & Kleitman? Controlled the extraneous variables, limited demand characteristics by not telling participants what stage or length of time sleeping, and operationalized the definition of 'dream' meaning the participants had to have content of a dream and not just an impression that they had one State the aim of Schachter & Singer To test the two factor theory of emotion Name the participants used in Schachter & Singer 184 male college students (Minnesota University) Explain how Schachter & Singer can be referred to as reductionist The idea of the two-factor theory of emotion attempts to simplify a complex concept like behavior so that it could be easily understood
