Goals of Psychological Research

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

  • A psychological research is conducted for the purpose of description, prediction, explanation, control of behaviour, and application of knowledge generated in an objective manner.

Detailed Explanation

Psychological research aims to describe behaviors, predict future behaviors, explain why behaviors occur, control or modify these behaviors, and apply the knowledge gained to improve people's lives. This means that psychologists are not just observing what people do, but they are also looking for patterns, reasons behind actions, ways to influence behaviors positively, and taking findings from research to practical situations.

Examples & Analogies

Imagine a doctor trying to understand a patient's symptoms. By analyzing these symptoms (description), the doctor can predict possible diseases (prediction), explain why the patient feels a certain way (explanation), suggest treatments to control the disease (control), and help the patient lead a healthier life (application).

Steps of Psychological Research

  • It involves the following four steps: conceptualising a problem, collection of data, analysing data, drawing and revising research conclusions.

Detailed Explanation

Psychological research typically unfolds in four major steps: First, researchers identify and define a specific problem they want to study (conceptualising a problem). Next, they gather data through various means like surveys or experiments (collection of data). After data is collected, they analyze it to draw conclusions (analysing data). Finally, they review their findings and may adjust their conclusions based on what they discover (drawing and revising research conclusions).

Examples & Analogies

Think of it like preparing a recipe. You first decide what dish to make (conceptualising a problem), then you gather all the ingredients (collection of data), cook and taste the dish to see how it turned out (analysing data), and then adjust the flavors if necessary or change the recipe for next time (drawing and revising conclusions).

Types of Data in Psychology

Unlock Audio Book

  • In psychological studies, different types of data including demographic, environmental, physical, physiological, and psychological information are collected. However, the data in psychological studies remain located in a context and are tied to the theory and method used for its collection.

Detailed Explanation

Psychologists collect various types of data depending on the nature of their research. Demographic data might include age and gender, environmental data might explore living conditions, while physiological data might assess physical health aspects. Psychological data focuses on mental processes. Importantly, all data collected must be viewed within the specific context of the study it comes from, acknowledging that different situations can affect the reliability and interpretation of that data.

Examples & Analogies

Consider a school setting where a psychologist wants to understand students' performance. They might collect demographic data like age and grade levels, environmental data such as classroom conditions, physiological information like stress levels before tests, and psychological insights into students’ attitudes about learning. Each type of data provides a piece of the puzzle, but without knowing the context (like whether it's during finals week), interpretations may be misleading.

Methods of Gathering Information

  • Different methods are used for collecting information. The observation method is used for describing the behaviour. It is characterised by selection of a particular behaviour, its recording and analysis.

Detailed Explanation

Psychologists employ various methods to gather information on behaviors. One common method is observation, where researchers watch subjects carefully and record specific behaviors. This method has distinct characteristics like selecting which behaviors to observe, recording what is seen, and analyzing the data collected afterward to understand behavioral patterns.

Examples & Analogies

Think of a wildlife documentary where filmmakers observe animals in their natural habitat. They carefully choose which behaviors to film (like hunting or grooming), capture those moments on camera, and later analyze the footage to learn about the animals' habits. Similarly, psychologists observe and document human behavior in various settings.

Experimental and Control Groups

Unlock Audio Book

  • The experimental method helps in establishing cause-effect relationship. The effect of the presence of independent variable on the dependent variable is studied using experimental and control groups.

Detailed Explanation

In psychological experiments, researchers use experimental and control groups to test hypotheses about cause-and-effect relationships. An experimental group receives a treatment or condition (the independent variable), while a control group does not. By comparing the outcomes of both groups, researchers can determine if the changes observed in the experimental group were indeed caused by the independent variable.

Examples & Analogies

Imagine testing a new fertilizer on a group of plants (experimental group) while keeping another set of plants without fertilizer (control group). If the fertilized plants grow taller, we can conclude the fertilizer had a positive effect. Without a control group, it would be difficult to know if improvements were due to the fertilizer or other factors, like sunlight or watering.

Understanding Correlational Research

Unlock Audio Book

  • The purpose of correlational research is investigating association between variables as well as making predictions. The relationship between two variables can be positive, zero or negative, and strength of association varies from +1.0 through 0.0 to –1.0.

Detailed Explanation

Correlational research does not involve manipulation of variables but examines existing relationships to see how one variable might predict another. A positive correlation means as one variable increases, so does the other, while a negative correlation indicates as one increases, the other decreases. The strength of this association is measured numerically, providing insight into how strongly linked two variables are.

Examples & Analogies

Consider how studying time and exam scores might correlate. If data shows that students who study more tend to score higher, that suggests a positive correlation. However, if those who watch more TV tend to score lower, that reveals a negative correlation. If there's no consistent pattern, we might find a correlation close to zero.

Survey Research Purpose

Unlock Audio Book

  • The focus of survey research is to inform about the existing reality. Surveys can be conducted by using structured and unstructured interviews, mailed questionnaires, and telephone.

Detailed Explanation

Surveys are designed to collect information from a large number of people to gauge opinions, attitudes, or behaviors. This can be done through various means like structured interviews, where questions are predetermined, or unstructured methods that allow for open-ended answers. Mailed questionnaires and telephone surveys are other methods that help researchers understand existing realities through broader population insights.

Examples & Analogies

Think of a company wanting to know what customers think about a new product. They might send out a questionnaire (survey) asking for opinions on taste, packaging, and price. The feedback helps them understand what people like or dislike and informs future decisions about product modifications.

Understanding Psychological Tests

Unlock Audio Book

  • The psychological tests are standardised and objective instruments which help in knowing one’s standing in comparison to others. Tests can be verbal, non-verbal, and performance types, which can be administered individually or to the entire group at a time.

Detailed Explanation

Psychological tests help assess various human characteristics in a systematic way. They are designed to be objective and standardized, meaning they can be consistently applied to anyone and yield comparable results. These tests might gauge intelligence, personality, skills, or other attributes through verbal and non-verbal questions and tasks.

Examples & Analogies

Imagine a school conducting standardized tests to measure student performance in math. Every student takes the same test, which helps teachers compare scores fairly across all students to see who excelled or may need further support.

Exploring Case Studies

Unlock Audio Book

  • The method of case study gives detailed in-depth information about a particular case.

Detailed Explanation

Case studies provide a deep view into individual cases, allowing researchers to gather extensive information and insights about specific phenomena. This could involve studying one person, a small group, or an event that reveals critical insights that can inform broader psychological understanding.

Examples & Analogies

Think of reading a biography of a famous leader. It dives deep into their life story, motivations, and decisions, providing insights that teach us not just about them, but about human nature and behavior in leadership. Similarly, case studies in psychology focus on individual instances to draw general conclusions.

Analyzing Data

Unlock Audio Book

  • The data collected through the use of these methods are analysed through quantitative and qualitative methods. The quantitative methods allow the use of statistical procedure for drawing conclusions.

Detailed Explanation

Once data is collected through various methods, researchers need to analyze the data, which is typically done using quantitative and qualitative methods. Quantitative methods involve statistical analyses that provide numerical data interpretation, while qualitative methods focus on descriptive analyses to understand deeper, subjective meanings.

Examples & Analogies

Imagine analyzing the results of a marathon where participants’ finishing times are recorded (quantitative analysis). You would calculate average times, compare statistics, and perhaps make graphs to visualize performance trends. In contrast, qualitative analysis might involve interviews with runners about their experiences, which could highlight emotional journeys that numbers alone wouldn't capture.

Limitations of Psychological Research

Unlock Audio Book

  • Lack of absolute zero point, relative nature of psychological tools, and subjective interpretation of qualitative data are some of the limitations of psychological enquiry.

Detailed Explanation

While psychological research provides valuable insights, it also encounters significant limitations. For instance, psychological measures often lack a true zero point, meaning they can only provide relative assessments rather than absolute measures. Furthermore, tools developed may be contextually biased, and qualitative data can often lead to subjective interpretations, making consistent analysis challenging.

Examples & Analogies

Think of it this way: measuring water can be done precisely in liters, but assessing happiness or intelligence isn’t that straightforward. Just as different cultures define happiness differently, psychological tools could become less effective if not adapted correctly to different contexts, similar to trying to plant a cactus in a rainforest without considering the environmental needs.

Ethical Considerations in Research

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

  • Ethical principles of voluntary participation of the subjects, their informed consent, and sharing of results with the participants must be followed by a researcher.

Detailed Explanation

Researchers must adhere to strict ethical principles that ensure participants' rights and welfare are respected. This includes ensuring voluntary participation without coercion, obtaining informed consent about the study's nature, and sharing findings with participants to promote transparency and trust in research.

Examples & Analogies

Imagine a doctor discussing a new treatment studying with patients. They must explain all procedures and risks clearly so patients understand what’s involved. Participants should also feel free to opt-out if uncomfortable, just as patients can choose not to take part in a trial if they don't agree with its processes.
