Empirical And Objective Methods Of Investigation

Albert Bandura created the bobo doll experiment in 1961, the aim of this experiment was to show that if children where witnesses to aggressive displays by an adult of some sort they would imitate this behaviour when given an opportunity. The tested group contained 36 young girls and 36 young boys all aged between 4 and 5 years which was then divided into 3 groups of 24 – the aggressive condition, the non aggressive condition and the control group. The first group involved the children watching aggressive models, where the children where then subdivided by sex of the role model they were exposed to. The second group

In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep

Methods used in psychological research are used to obtain quantitative or qualitative data. Quantitative data is more often than not derived from methods such as experiments and statistics analysing data using surveys, questionnaires and interviews. Qualitative data tends not to be aimed at finding exact measurements in its findings, but is more concerned with evidence collection and analysis through practices such as observation and ethnography (using observations through involvement in activities over a period of time) (Brownlow 2011).

Instructions: This is a group activity that you will start in class and complete at home. For each of the following, note, whether the research design used is an experiment, a quasi-experiment, or a correlational approach and why. If a study is an experiment, identify the independent variable and the dependent variable. Please type your answers in complete sentences.

Researchers or research teams who elect a quantitative study are going to determine the relationship between an independent variable and a dependent variable within a population (Babbie, E.R., 2010). There are two types of quantitative study designs: descriptive and experimental. A descriptive design typically measures the subject once and establishes the association between the independent and dependent variables (Mujis, D, 2010). An experimental design measures the subject before and after a treatment and establishes causality between the variables (Brians, C.L. et al, 2011).

A person should consider I/O psychology as a science because of its use of scientific research and its practice and because of its use of descriptive and inferential statistics (Spector, 2012), “I/O psychologists do many different jobs in a wide variety of settings” (p. 6). One divides I/O settings into two areas of concern, which are scientific research and practice. The research area provides certain principles, which one applies in practice. The activity of practice involves using psychological principles for solving problems of the real-world. Scientific research and practice are both important in I/O psychology. I/O psychologist perform studies were the requirements of statistical methods are necessary for analysis of data. Statistical methods are used to perform studies are descriptive and inferential statistics. I/O psychologists use descriptive statistics for summarizing study results. I/O psychologists use inferential statistics for the purpose of interpreting the results of studies by using different statistical tests.

Research, systematic inquiry aimed at the discovery of new knowledge, is a central ingredient of the scientific method in psychology. It provides the key to understanding the degree to which hypotheses (and the theories behind them) are accurate. Just as we can apply different theories and hypotheses to explain the same phenomena, we can use a number of alternative methods to conduct research.

The Bobo doll experiment was the collective name of experiment conducted by Albert Bandura in 1961 and 1963 when children’s behaviors after watching a violence video. This experiment done in children. Albert Bandura made a video of children who used to more violence video. Instated out of 100% of people, 60% boys are more aggressive comparison to girls, because boys play more aggressive and dramatic games than a girl. According to the research, Albert found that both girls and boys who watched the older people, “how they play and beat the doll”. In our country we believe that, we learn from our siblings, if brother and sister are nice and good than small child also good. Children learn what they saw and lots of kids spend more quality time

Albert Bandura conducted a famous experiment known as the Bobo doll experiment. The experiment has helped in developing the social learning theory.

Describe the specific type of research design that was used and discuss why it is considered experimental or quasi-experimental.

First, laboratory experiments. Laboratory experiments are research methods that help to establish cause-effect relationship between two variables. They are applied for developing the casual relationship of manipulated variables which help to increase psychological

The method used for the study was quantitative, this was chosen rather than a qualitative as this deals with facts and figures and is an investigatory type of study. This can be either experimental or non experiment. Experimental is the method used in this study which looks at cause and effect, and involves dependent and independent variables. (Balnaves and Caputi, 2001) A qualitative study can be described as interpretive which deals with personal thoughts and feelings (Flick, 2009).

Psychological research describes investigations psychologists undertake in order to review and analyse a specific hypothesis, (a theory about the relationship between defined variables). Research allows theories to be confirmed, amended or rejected and often leads to further research as requirements evolve. Psychological research can take many forms, from laboratory based experiments to non-invasive viewing of subjects in their own environment. This research can take place using human or non-human subjects and the analysed results applied to human behaviour or experience within many disciplines including, education, legal or occupational.

In Psychology 101 we learned that research methods are used in order to understand our mental and behavioral processes by making observations in a systematic way, following strict rules of evidence and thinking critically about that evidence. This scientific research is based on theories (tentative explanations of observations in science), hypotheses (predictions based on a theory) and replication (testing a hypothesis in more than one study). Some of the different research methods are firstly, descriptive studies. Descriptive studies are studies that use survey methods, naturalistic observation and clinical methods. Another research method is correlational studies. Correlational studies are studies that help one to determine if a relationship exists between two or more variables and if so it tells one how strongly those two variables relate to one another. With in correlational studies one can have positive correlation (as one variable increases or decreases so does the other), negative correlation (variables go in opposite directions) or zero correlation (no relationship between the variables). Another research method is formal experiments. Formal experiments are studies that allow us to draw conclusions about how one variable may cause or have an effect on another variable. With in formal experiments there are four elements, which are the independent variable (variable that is manipulated or controlled), the dependent variable (variable that is measured), the experimental
