Answer:
The person who conducts the experiment is called the experimenter.
5. Define / Explain the concepts in 25 – 30 words each.
Question 1.
Replicability
Answer:
Replicability is one of the key features of science. Scientific knowledge can be replicated under the same circumstances as the original experiment. This ensures reliability of results towards establishing a scientific theory.
Question 2.
Correlation coefficient.
Answer:
Correlation coefficient is the measurement of the correlation between two or more variables. Its value extends between -1.00 to +1.00. The concept was first introduced by Sir Francis Galton. The Pearson product-moment correlation coefficient is the most commonly used type of correlation coefficient.
6. Write short notes on the following in 50 – 60 words each.
Question 1.
Observation method
Answer:
Observation method is a research method that is employed in conditions where experiments may not be possible or even necessary. Observation is used by child psychologists and social psychologists. It may be carried out in a natural setting, for e.g., observing candidates waiting their turn for an interview. It may also be carried out in controlled conditions.
The following factors should be kept in mind while carrying out the observation
- it should be done systematically.
- a comprehensive list of behaviours to be observed must be prepared.
- the persons should not be aware of being observed.
The disadvantages of observation are:
- it is a time consuming method.
- objectivity is difficult to maintain during observation.
- it is difficult to establish cause-effect relationships.
Question 2.
Survey method
Answer:
A survey is a research method used to collect data from a pre-determined group of respondents, i.e., a sample. It is used to obtain information about the preferences, opinions, etc., of the ‘sample’ population. It makes use of tools like questionnaire, checklist, interviews, etc. Survey method is employed by social psychologists, industrial psychologists, etc. The researcher must ensure that-
- sample of respondents is representative of the population.
- questions should not be ambiguous.
The disadvantages of survey method are:
- it is a very subjective method,
- it lacks reliability.
Question 3.
Case study method
Answer:
Case study method is a qualitative research method employed by clinical psychologists. It provides intensive, descriptive information about an individual from multiple sources such as family, peers, school, academic and health records, etc. This helps to assess the person’s level of psychological and social functioning. Researchers may employ techniques like observation, interview, psychological tests, etc. Psychologist such as Sigmund Freud and Jean Piaget made extensive use of case study method. However, this method is very time consuming and subjective.
Question 4.
Importance of rationality
Answer:
Rationality implies being agreeable to reason. According to Stanovich, “Rationality involves adaptive reasoning, good judgement and good decision making.”
According to Dr. Albert Ellis, rationality helps a person to successfully attain goals and be happy. He proposed Rational Emotive Behavioural Therapy (REBT), which is a popular intervention method in counselling psychology.
Rationality is important because:
- It allows us to make decisions in new or unfamiliar situations by helping us to gather and process relevant information.
- It enables the person to exhibit tolerance and flexibility.
- A rational person accepts oneself unconditionally and assumes responsibility for their own behaviour.
- Rationality helps to understand and respect the views and interests of others.
7. Define / Explain the concepts in 25 – 30 words each.
Question 1.
Science
Answer:
The word science is derived from the Latin word ‘Scientia’ which means ‘knowledge’. Science is the pursuit and application of knowledge and understanding of the natural and social world, following a systematic methodology based on evidence. The key features of science are empirical evidence, objectivity, scientific causality, systematic exploration and replication.
Question 2.
Objectivity
Answer:
Objectivity is one of the key features of science. It refers to the ability to observe and accept facts as they exist setting aside all sources of expectations, values, prejudices, etc. Science objectively studies some particular phenomenon.
8. Answer the following questions in detail.
Question 1.
Explain the types of correlation.
Answer:
A correlation refers to a statistical tool used to measure the relationship between two or more variables.
If the change in one variable is accompanied by a change in the other variable, this interdependence is called correlation. It is measured by correlation coefficient which extends between -1.00 to + 1.00.
The types of correlation are:
(i) Positive correlation – Both variables either increase or decrease at the same time, for e.g., extent of rehearsal (revision)↑ and recall score↑.
The value of positive correlation from 0.00 to + 1.00. It is represented as: variable 1 variable 2
(ii) Negative correlation – An increase in one variable is associated with a decrease in the other and vice-versa. The value of the correlation is between 0.00 to -1.00, for e.g., bunking of lectures (↑) and score in exams (↓).
(iii) Zero correlation – A change in one variable leads to no significant change in the other variable, for e.g., height and intelligence.
Question 2.
Explain some of the challenges in establishing psychology as a science.
Answer:
Many criticisms of psychology as a science have been made on practical, philosophical and ethical grounds. The challenges in establishing psychology as a science are:
(i) It is in preparadigmatic state – According to American philosopher, Thomas Kuhn, psychology is still in a preparadigmatic state as it has not succeeded in producing a cumulative body of knowledge that has a clear conceptual cove.
(ii) Issues related to objectivity and validity – Methods used in psychology such as introspection, surveys and questionnaires are subjective. Due to this, psychology lacks two criteria of science, i.e., objectivity and validity.
(iii) Issues related to predictability and replicability – In psychology it is difficult to make exact predictions as people respond differently in different situations. Test result are more varied and hence difficult to replicate.
(iv) Objectifying humans – According to some psychologists, subjecting human behaviour to experimentation amounts to objectifying individuals.
Question 3.
Explain the key features of science.
Answer:
The word science is derived from the Latin word ‘Scientia’ which means ‘knowledge’. Science is the pursuit and application of knowledge and understanding of the natural and social world, following a systematic methodology based on evidence.
They key features of science are:
- Empirical evidence – It refers to acquiring information through direct observation or experiments. Scientific knowledge is based on verifiable evidence.
- Objectivity – This refers to the ability to observe and accept facts as they exist, setting aside all sources of expectations, values, prejudices, etc.
- Scientific causality – Science aims to establish a cause-effect relationship between the variables under consideration, i.e., the effect of the Independent Variable on the Dependent Variable.
- Systematic exploration – Science adopts a sequential procedure for studying various phenomena. It includes scientific steps like formulating a hypothesis, collection of facts, scientific generalisation etc.
- Replication – Scientific knowledge can be replicated under the same circumstances as the original experiment. This ensures reliability of results towards establishing a scientific theory.
- Predictability – Science involves describing and explaining phenomena as well as to make predictions accordingly.
Question 4.
Write detailed information of the experimental method in psychology.
Answer:
The systematic observation about a certain problem under controlled laboratory conditions is called an experiment.
For example, Albert Bandura conducted experiment to investigate if social behaviours i.e., aggression can be acquired by observation and imitation. The steps involved in an experiment are:
- identifying the problem
- formulation a hypothesis
- selecting an experimental design
- conducting the experiment and data collection
- data analysis
- drawing conclusions
The key terms of experimental method with examples are:
- Problem: To study the effect of music on the level of blood Pressure.
- Hypothesis: The music will help in regulating the level of blood pressure.
- Independent variable: Music.
- Dependent variable: Level of blood pressure.
- Intervening variables: Age, gender, all other sounds other than music, etc.
- Experimenter : A person who will be conducting this experiment. (May be you or your psychology teacher.)
- Participant : A person on whom this experiment will be conducted. (May be your family member/ friend.)
The two variables in an experiment are:
- Independent Variable (I.V.) – It is the variable that the experimenter manipulates or changes systematically to study it’s effect on the D.V. (Cause).
- Dependent Variable (D.V.) – the variable that may change due to manipulation of the I.V. (effect).
The features of the method are:
- it is the most objective and scientific method of studying behaviour
- it helps to establish cause-effect relationship between two or more variables
- the findings of an experiment are verifiable
The limitations of the method are:
- it may not be possible to control all intervening variables
- it has a limited scope, i.e., there may be ethical constraints or risk factors
- experimenter’s expectations or participant attitude may influence the conclusions
Question 5.
Explain the characteristics of a rational individual.
Answer:
One of the significant aims of individuals is attainment of happiness. However, in the pursuit of happiness, one should not be driven by irrational influences or compromise on social norms and ethics. Psychology helps to improving life quality by applying the concept of rationality in daily life. According to Stanovich, “Rationality involves adaptive reasoning, good judgement and good decision making.”
According to Dr. Albert Ellis, rationality helps a person to successfully attain goals and be happy. He proposed Rational Emotive Behavioural Therapy (REBT), which is a popular intervention method in counselling Psychology.
According to Ellis, rational people possess characteristics such as:
- Understanding both self-interest and social interest – Rational people understand what choices help them to grow and take responsibility for their actions. They are also careful not to violate other’s rights.
- Self-direction – The person does not demand excessive attention or support from others as he/she assumes the responsibility for his/her own life.
- Tolerance – It is the willingness to accept beliefs and behaviour patterns of others that may differ from our own way of thinking.
- Flexibility – Rational people tend to be flexible and unbiased in their thoughts and actions.
- Self-acceptance and self-responsibility – A rational person accepts him/herself unconditionally as well as responsibility for his/her thoughts, emotions and behaviour.
The concept of rationality can be explained as:
| B (Balance) | Balance between self-interest and interest of others |
| E (Estimate) | Estimate the time, efforts, gains and losses |
| R (Respect) | Respect oneself and others |
| A (Affiliate) | Affiliate with others |
| T (Tolerate) | Tolerate oneself and others |
| I (Intergrate) | Integrate personal wellbeing with social wellbeing |
| 0 (Optimize) | Optimize potential fully |
| N (Navigate) | Navigate path of success |
| A (Accept) | Accept the limitations and overcome them |
| L (Live) | Live life fully |
How Rational Am I?
Question 1.
Identify the strongest and the weakest characteristics in you from those explained by Dr. Albert Ellis.

According to Dr. Albert Ellis, some characteristics of rational persons are:
- Understanding self-interest and social interest
- Self-direction
- Tolerance
- Flexibility
- Self-acceptance and self-responsibility.
The strongest characteristic in me is self-direction. The weakest characteristic in me is flexibility.
Question 2.
