INTRODUCTION
Psychology is the study of the conscious and insensible behaviour of the individuals. This
project report consist of three different case report which consist of three different scenarios.
First case study provides the detail on Dr. butlers experiments which is performed to test the
effect of appetite on dreamy sleep which is studied while evaluating different undergraduates
actions on healthy and unhealthy food. In second scene different psychological and behavioural
approach of individuals is studied when they are influenced to the particular environment. Third
approach of the project report consist of the role of eye witness in the robbery is studied. This
report which provide the role of police in influencing the thought process of past eye witness
case outcome (Zerón-Rugerio and et. al., 2022).
MAIN BODY
QUESTION 1
Dr. Butler was the psychologist who used the experiment to study the effect of food on
dreamy sleep. Butler wants to study the alteration in every day physiological sleep cycle due to
human action so they incorporated the experiment management for almost 1 month duration.
Main aim of the Butler is to examine the change in sleeping routine due to alteration in food
form or difference in consumption time. To demeanour the plan of action for experiment,
undergraduates students were used where the faction of students were divided into two different
group. However, first group comprise of 20 males merged with around 5 females. They were
provided with the junk foods before their bedtime. And the other group contain males and
females in the ratio of 15 and 10 respectively. They were supplied with the fresh healthy food
regime before their bed time. To analyse the result of long experiment conclusion weekly
feedbacks were taken from the students to understand either they had a dream sleep or not. Since
Butler was fond of the dreamy sleep so they have probe the research to measure the quantitative
and prompt role of food on delighted sleep (Lentz and Brown, 2019).
Variable is the quantity element that is likely to be diverge due to many constituents in
the experiment. Dependent variable is the variable that is effected usually due to alteration in
independent variable of the research. They are the consequence or the conclusion caused due to
the independent variable. These are the quantity which depend on various experimentation
factors. For example students exam result is dependent on the amount of study they had done or
1

their concentration power and many more. In this study the dependent variable is sleep. As sleep
occurrence depend on the kind of food consumed by the individuals (Reutrakul and Van Cauter,
2018).
Independent variable are the variable that are the one which are not altered due to effect
of any other factors. These are the element of the experiment that can be modify or changed by
the experimenter. The change in independent variable will always influence the the dependent
variable of the research. In this case study, Dr. Butler used the independent variable are appetite
and the gender. Therefore, change in appetite will alter the dreamy sleep of the individuals. Sleep
is also dependent on the gender. This is seen because male and female have variation in their
circadian rhythm, body operation and hormone liberation which effects the dreamy sleep of the
individuals. It has been seen that women have more fragmented sleep than men (Ji and et. al.,
2019).
Extraneous variables are the factor which not only effect the sleep which is dependable
variable but it also effects the appetite consumption which is the in-dependable variable.
Extraneous variable in this experiment is Dr. Butler's case study is Undergraduate students and
the magnitude of food that have been consumed by them before their sleeping routine. So these
are the elements of the experiment that is need to be in commanding form till the experiments
continue. They can change the research result as if the food quantity is enhanced then it might
effects the cardiac rhythm which will negatively effect the dreamy sleep. If the experiment is
performed on elderly individuals and consuming junk food or even consuming late in night will
effect their health conditions majorly and in case of graduates only discomfort is measured
(Morin, Hozer and Costemale-Lacoste, 2018).
