Main Assumptions
What is the biological approach controlled by?
Biological Systems and Processes
What's the sample?
10 right-handed healthy females
What was the purpose of an EEG?
To record brain activity and eye movements and to show that we have several stages of sleep during the night (REM and nREM).
What was the research method and design?
Lab experiment
Independent groups design
What is Nature vs. Nurture
A debate determining the factors of Genetics and Environment.
What systems and Processes is the Biological Approach controlled by?
Evolution, Genes, Hormones, or the Nervous System.
What's the Aim of the study?
To show that emotive images will be remembered better than those that have little emotional impact on an individual.
or
Whether the amygdala is sensitive to varying degrees of emotional intensity to external stimuli.
or
Whether the level of intensity enhances memory for the simuli.
What sampling technique was used?
Volunteer
What was the dependent variable?
The participant's emotional states during elements of the study.
What's the double-blind technique?
When both the participant and researcher are unaware of which condition the participant is in to prevent demand characteristics.
By manipulating and measuring biological responses.
How many scenes were the participants shown?
96 scenes
What methods were used?
Electronic recordings, observation, and diaries.
What's the Two-Factory theory of emotion?
If given a state of physiological arousal, for which the individual has no adequate explanation, cognitive factors can lead the individual to describe their feelings with any of a number of emotional labels.
Why have biological responses evolved?
Because it helps us to survive.
What are the three studies of the Biological Approach?
Canli et al.
Dement and Kleitman
Schachter and Singer
What was the main conclusion of the study?
There is indeed a relationship between the emotional intensity of stimuli and memory.
How long was the cycle length of the REM stage?
70-104 minutes (An average mean of 92)
What was the sample?
185 male college students taking classes in introductory psychology at the University of Minnesota.
What genetic quality is involved in emotional responses?
Hormones, such as adrenaline that triggers excitement in responses.
What is the aim of Chapter two?
To introduce you to the biological approach of psychology and explore three studies from this approach.
What were the average correlation coefficients between participants' emotional intensity ratings?
-0.66 and 0.68
What do the EEG spindles report?
Feelings (anxiety, pleasantness, detachment)
What was the injection given to the participants called?
Suproxin
How has the biological approach helped during these studies?
Because it shows the biology of your body during scenarios, such as emotional reaction and amygdala reaction to certain emotional intensities your body experiences.
