1. The research in the article focuses on a particular Research Method. Identify the method used and discuss the strengths and weaknesses of this method.

The research method used in the journal article 'Effects of Attractiveness and Nature of Request on Helping Behaviour' is a field experiment. A field experiment is carried out in a real life setting and involves manipulating an independent variable to see if it has an effect on a dependant variable; participants do not usually know they are taking part in an experiment(Complete Psychology, pg371). One of the strengths of this research method is that the results have high ecological validity, meaning they are more likely to reflect real life behaviour …show more content…

An experimental hypothesis is based on background research on the area of study and should be a testable statement (complete psychology, pg 638). An independent variable is the factor which is manipulated by the researcher, the dependant variable is what is measured by the researcher and is affected by the independent variable. The independent variable in the experiment in the article is attractiveness and the nature of request; the dependant variable is the level of help received from strangers. The hypothesis for this experiment could either be one tailed, predicting the direction of change that manipulating the independent variable would have on the dependant variable, for example “Increased attractiveness of an individual will increase the level of help received” or two-tailed, predicting change but not indicating the direction, “The attractiveness of an individual will have an effect on the level of help received.” With every hypothesis there is a null hypothesis, which states that there is no relationship between the variables but that the results are a result of chance. If it can be shown that t chance is unlikely to be the reason, then we can disprove the null hypothesis, giving support to our experimental hypothesis (complete psychology). A null hypothesis for the experiment in the article could be “The attractiveness of an

These actions taken by the city officials helped with reducing the occurrence of major crimes, including rape and murder. With the power of context theory however, Gladwell discusses the environmental and situational factors that affect the behavior of others. He refers back to the subway shooting with Goetz, and two historical examples of the Stanford Prison experiment, which involved fake guards brutally abusing fake prisoners, and the Hartshorne/May experiment, which proved students were likely to not cheat due to varying factors, as examples of how the environment one is surrounded in can influence the decisions they make (Gladwell). This theory of Gladwell’s that environmental stimuli can easily trigger the human brain to react and make decisions that contradict how one normally perceives a situation, can be used as an analytical tool to define and explain the actions and decisions of

Two ‘prisoners’ had to be removed early from the experiment and several were emotionally distressed. However, it does show the power of situation on people’s behavior and decision-making. The people chosen for the experiment were regular students. They were assigned to their roles randomly – the prisoners had not done anything ‘wrong’ and the guards had not earned their position of authority.

There are many ways to find out how individuals would react in certain situations, for example, by putting individuals in a simulation. Causing stress and discomfort to individuals in order to gain knowledge is at times necessary. For example, Stanley Milgram’s experiments which focus on obedience to authority and the extent a person is willing to ignore their own ethical beliefs and cause pain to another individual, just because he is ordered to do so. Stanley Milgram writes about his experiments and results in his article “The Perils of Obedience”. In his experiments Stanley Milgram causes subjects who have volunteered to be a part of them some stress and discomfort in order to receive relevant results.

This essay will discuss the role of ecological validity in psychological research, drawing on material from the DE100 textbook ‘Investigating Psychology’. It will begin by giving a description of what ecological validity is, and consider it in relation to different examples of research. The research used to discuss the role of ecological validity will be based around social learning and aggression, behaviourism, and memory. Firstly the study of Bandura et al. will be considered, his experiments on children copying violent behaviours using the Bobo doll experiment.

Latane and Darley used this method to examine bystanders behaviour. (Latane and Darley, 1970, cited in Jovan Byford, 2014, p. 229 - 234) Latane and Darley counted the number of participants in each condition who responded to the staged emergency within two minutes in the experiment that they created. They compared the outcomes from each condition and presented the finding of their experiment in the form of graphs and numbers. (Latane and Darley, 1970, cited in Jovan Byford, 2014, p. 229 - 231) Therefore, the experimental method, without a shadow of a doubt is a quantitative method and it is thought to uncover the general

One of the most infamous experiments conducted in the history of psychology was the Stanford Prison Experiment. The main objective of this experiment was to see what effects would occur when a psychological experiment into human nature was performed. As I read through the material provided, I noticed that my thoughts on the matter were similar to many; that it was a complete failure as a scientific research project. However, his findings did provide us with something much more important that is still being talked about today; insight into human psychology and social behavior.

A group of scientists has hypothesized that females are more likely to cooperate in helping someone who dropped their papers. However, the males resulted to participate in helping a person when the papers fell. Scientists have also inferred that if people are walking alone they would tend to help more because people that are in groups are easily distracted with one another. However, in experiments done, females who walked in groups were proven to help more. It came to their attention that people are most likely to help if they are in groups because they feel more comfortable.

Abortion: Why it should be illegal. Abortion Abortion is the deliberate termination of human pregnancy, most often performed in the first 28 weeks of pregnancy, but a fetus has a heart beat after 3 weeks, one day after fertilization is when the little heart starts to beat. If something has a heart beat it has a right to life and protection. A woman has the "right" to choose if her child lives or dies, but what about the baby? Doesn’t the baby get a say?

This assignment includes; Strengths, examples and weaknesses of the following psychological research; Bandura et al, Skinner & Loftus and Palmer. In order discuss and come to a conclusion as to why ecological validity is important in psychological research. It is important to note that; Ecological validity is the degree to which behaviours reflect the behaviours of everyday life. In Chapter 3 Bandura et al demonstrated whether children were witnesses to an aggressive display of play.

One of the most interesting subjects that depicts many explanations about human behavior is psychology. Every human being tends to have a distinct behavior, depending on the situation that he or she was exposed to. The presence of other human beings cause the thoughts, feelings, and behaviors of the person to be controlled or influenced. There is a considerable amount of factors in which the actions of human beings around them are responsible for the process of making their decisions.
