3. Answer the following in one sentence each.

Question 1.What is meant by intelligence?
Answer: David Wechsler defines intelligence as, "the aggregate or global capacity of an individual to act purposefully, to think rationally and to deal effectively with his environment."
In simple words: Intelligence is the overall ability to think logically, solve problems, and adapt well to one's surroundings. It's about how effectively a person interacts with their world.

🎯 Exam Tip: Memorize key definitions from prominent psychologists, as precise wording often earns full marks.

Question 2.Who is considered as the father of intelligence test?
Answer: Alfred Binet is considered as the father of intelligence tests.
In simple words: Alfred Binet created the first practical intelligence test, marking the beginning of systematic intelligence assessment. His work laid the foundation for modern IQ testing.

🎯 Exam Tip: Associate key figures with their foundational contributions to the field of psychology, such as Alfred Binet with intelligence testing.

Question 3.What is meant by verbal tests of intelligence?
Answer: Verbal tests of intelligence make use of words and numbers to measure intelligence and subjects respond verbally to the test items, for e.g., WAIS, Army Alpha Test, etc.
In simple words: Verbal intelligence tests use language-based tasks, like vocabulary or arithmetic, and require spoken or written answers. They assess a person's ability to understand and use words and numbers.

🎯 Exam Tip: Be able to describe the nature and examples of verbal intelligence tests, understanding their reliance on linguistic ability.

Question 4.What is meant by individual test of intelligence?
Answer: Individual tests of intelligence are tests which can be administered to a single person at a time, for e.g., Stanford Binet Scales, WAIS, Koh's Block Design Test, etc.
In simple words: An individual intelligence test is given to one person at a time, allowing the examiner to closely observe and interact with the test-taker. This provides a detailed assessment of their cognitive abilities.

🎯 Exam Tip: Differentiate individual and group tests by their administration method and the depth of observation they allow.

4. Define / Explain the concepts in 25 - 30 words each.

Question 1.Mental Age
Answer: Alfred Binet introduced the concept of Mental Age. It is defined as the age at which the person successfully performs on all items of the test prepared for that age level. Mental Age need not correspond to Chronological Age. If Mental Age (MA) is the same as Chronological Age (CA), the person has average intelligence. For e.g., Sumit aged 10 years has successfully performed all items on the test for age 12. Hence, his Mental Age will be 12 years, i.e., he has above average intelligence.
In simple words: Mental Age (MA) refers to the intellectual level at which a person performs, based on typical performance for a given chronological age. It reflects how advanced or delayed one's cognitive abilities are compared to their actual age.

🎯 Exam Tip: Clearly distinguish between Mental Age and Chronological Age, and understand how their comparison indicates intellectual level.

Question 2.Social Intelligence
Answer: E.L. Thorndike proposed the term Social Intelligence. Howard Gardner included 'interpersonal intelligence' in the Multiple Intelligences Theory. According to Karl Albrecht, 'Social intelligence - is the ability to get along well with others and to get them to cooperate with oneself.' A continued pattern of nourishing behaviour indicates a high level of social intelligence. Such persons are skilled at interacting with and understanding people around them. They respect and encourage others. They effectively comprehend social dynamics.
In simple words: Social intelligence is the ability to understand and interact effectively with others. It involves reading social cues, building rapport, and navigating social situations skillfully, leading to positive relationships and cooperation.

🎯 Exam Tip: Define social intelligence by focusing on its practical applications in interpersonal interactions and the ability to manage social dynamics.

Question 3.Emotional Intelligence
Answer: The term Emotional Intelligence was used for the first time by John Mayer and Peter Salovey. The concept of emotional intelligence was popularized by Daniel Goleman. It is defined as "the ability to perceive and monitor one's own and others emotions, to discriminate among them and to use this information to guide one's thinking and actions." Emotional Intelligence refers to a set of cognitive abilities such as perceiving emotions, using emotions to facilitate thought, understanding emotions and managing (regulating) emotions. Persons with high emotional intelligence tend to be emotionally stable, patient, optimistic, enthusiastic and calm.
In simple words: Emotional intelligence is the capacity to understand and manage one's own emotions, as well as perceive and influence the emotions of others. It enables better decision-making, empathy, and effective relationships.

🎯 Exam Tip: Explain emotional intelligence by listing its core components: recognizing, understanding, and managing both personal and others' emotions.

5. Write short notes on the following.

Question 1.Intelligence Quotient
Answer: Intelligence is the highest attribute of human beings. Different psychologists have defined intelligence differently. Lewis Terman explains intelligence as, “an ability to think on an abstract level." David Wechsler defines intelligence as, “the aggregate or global capacity of an individual to act purposefully, to think rationally and to deal effectively with his environment.” Intelligence Quotient refers to a measurement of intelligence.. In 1912, William Stern introduced the concept of intelligence quotient (IQ). Terman, refined the formula for calculating IQ, which is as stated below- \[IQ = \frac{MA}{CA} \times 100\] Example: Ankush who is 10 years old has a Mental Age of 11 years. Let us calculate his IQ. MA = 11 years CA = 10 years IQ = ?
\[IQ = \frac{MA}{CA} \times 100\]
\[ \implies IQ = \frac{11}{10} \times 100\]
\[ \implies IQ = 110\] Ankush has an IQ of 110.
In simple words: Intelligence Quotient (IQ) is a score derived from standardized tests to measure a person's cognitive abilities, typically calculated by dividing mental age by chronological age and multiplying by 100. It provides a numerical representation of intellectual performance relative to others.

🎯 Exam Tip: Clearly state the formula for IQ and demonstrate its application with an example, explaining each variable.

Question 2.Charles Spearman's theory of intelligence
Answer: Intelligence is the highest attribute of human beings. Different psychologists have defined intelligence differently. Lewis Terman explains intelligence as, “an ability to think on an abstract level." David Wechsler defines intelligence as, "the aggregate or global capacity of an individual to act purposefully, to think rationally and to deal effectively with his environment." In 1927, Charles Spearman with the help of a statistical method called factor analysis separated and identified two different factors of intelligence viz. General factor (g) and Specific factor (s). 1. General factor is the minimum competence required to carry out daily work. 2. Specific factor includes abilities which are required to solve problems in specific areas.
In simple words: Spearman's two-factor theory suggests intelligence consists of a general factor ('g'), which underlies all intellectual tasks, and specific factors ('s'), which are unique to particular tasks. The 'g' factor represents overall mental energy, while 's' factors explain individual differences in specific skills.

🎯 Exam Tip: When explaining Spearman's theory, emphasize the distinct roles of the general (g) factor and specific (s) factors in intelligence.

Question 3.Verbal tests of intelligence
Answer: Intelligence is the highest attribute of human beings. Different psychologists have defined intelligence differently. Lewis Terman explains intelligence as, “an ability to think on an abstract level." David Wechsler defines intelligence as, "the aggregate or global capacity of an individual to act purposefully, to think rationally and to deal effectively with his environment." On the basis of material used in the tests, intelligence tests can be classified as Verbal tests and Non-verbal tests of intelligence. Intelligence tests that use language (words or numbers) for measuring intelligence are called verbal tests of intelligence. In these tests subjects are required to respond verbally to test items. Army Alpha Test, Wechsler's Adult Intelligence Scale (WAIS), etc., are some of the examples of verbal tests of intelligence. These tests are language and culture bound and hence cannot be used with children, illiterates etc. However, they are useful in measuring higher mental abilities.
In simple words: Verbal intelligence tests rely on language, using words and numbers to assess cognitive abilities, and require verbal responses. While good for measuring higher mental functions, they are limited for children or illiterate individuals due to their language and cultural dependence.

🎯 Exam Tip: Highlight both the strengths (measuring higher mental abilities) and weaknesses (language/culture bound) of verbal intelligence tests.

Question 4.Non-verbal tests of intelligence
Answer: Intelligence is the highest attribute of human beings. Different psychologists have defined intelligence differently. Lewis Terman explains intelligence as, “an ability to think on an abstract level." David Wechsler defines intelligence as, "the aggregate or global capacity of an individual to act purposefully, to think rationally and to deal effectively with his environment." On the basis of material used in the tests, intelligence tests can be classified as Verbal tests and Non-verbal tests of intelligence. Intelligence tests that use pictures, designs, material objects, etc., to measure intelligence are called non-verbal tests of intelligence. In these tests language is not used to measure intelligence. In these tests subjects are not required to respond verbally to test items. Non-verbal tests are of two types viz. 1. Performance tests for e.g., Koh's Block Design test, Dr. Bhatia's Non Verbal test, Alexander's Pass-along test, etc. and 2. Paper-pencil tests for e.g., Raven's Standard Progressive Matrices.
In simple words: Non-verbal intelligence tests measure cognitive abilities using pictures, designs, or objects, without requiring language skills or verbal responses. They are particularly useful for assessing intelligence in children, illiterates, or individuals with language barriers.

🎯 Exam Tip: Focus on the visual and practical nature of non-verbal tests and their suitability for diverse populations where language is a barrier.

Question 5.Artificial Intelligence
Answer: The term Artificial Intelligence was suggested by John McCarthy. Artificial intelligence is an innovation created by human intelligence. It is a field of study that combines computer science, algorithms, psychology, etc. It refers to enabling software programmes and computer systems to perform tasks that normally require human intelligence, such as visual perception, speech recognition, weather forecasting, language translation, etc. Artificial intelligence can take decisions only on the basis of stored information and so cannot be an alternative to human intelligence. Artificial intelligence has immense applications in daily life as well as to solve critical problems. Artificial intelligence is used in devices like robots, computers, self-driving cars, automatic missiles, smart phones, medical diagnostic tools, etc.
In simple words: Artificial Intelligence (AI) is a technology enabling machines to mimic human intelligence by performing tasks like learning, problem-solving, and decision-making. While it excels in processing data, AI lacks human traits such as emotional understanding and creativity.

🎯 Exam Tip: Define AI by its core function (simulating human intelligence) and provide diverse examples of its application in modern technology.

(i) Meaning - Intelligence tests that can be administered to a single person at a time are called individual tests of intelligence, for e.g., Stanford Binet Scales, Koh's Block Design Test, etc.
(ii) Advantages- 1. The test administrator can establish a rapport with the client. 2. The test administrator can get additional information about the client's feelings, moods and expressions during testing. 3. Individual tests are more capable of measuring creative thinking, compared to group tests.
(iii) Disadvantages- 1. Individual tests are time consuming and costly to administer. 2. Individual tests require a trained and skillful examiner to administer, score and interpret them. 3. These tests cannot be used for mass testing.
In simple words: Individual intelligence tests are administered one-on-one, allowing for a deep understanding of the test-taker's unique abilities and emotional state during the process. However, they are resource-intensive, requiring skilled examiners and more time per person.

🎯 Exam Tip: When discussing individual tests, highlight the benefits of personalized interaction for nuanced assessment, balanced against their practical limitations in terms of time and cost.

Question 2.Write in brief about group tests of intelligence (i) Meaning (ii) Advantages (iii) Disadvantages
Answer:
ℹ️ चित्र व्याख्या (Diagram Explanation): यह आरेख बुद्धि परीक्षणों के प्रकारों को दर्शाता है, जो दो मुख्य आधारों पर विभाजित हैं: प्रशासन के तरीके (व्यक्तिगत और समूह) और सामग्री का प्रकार (मौखिक और गैर-मौखिक)। यह संरचना विभिन्न बुद्धि परीक्षण विधियों की एक स्पष्ट रूपरेखा प्रदान करती है।
(i) Meaning - Group test of intelligence are tests that can be administered to more than one person at a time, i.e., for mass testing, for e.g., Army Alpha and Army Beta Test, OTIS self-administrating tests, etc.
(ii) Advantages- 1. Group tests are less time consuming and more economical to administer. 2. In administrating of group tests, the role of the examiner is minimal. So, he/she need not go through any specialised training. 3. These tests can be used in cases where mass testing is needed.
(iii) Disadvantages- 1. The test administrator has much less opportunity to establish rapport, obtain cooperation and maintain interest of the clients. 2. Compared to individual tests, group tests are less capable of measuring the creative aspect of intelligence.
In simple words: Group intelligence tests are efficient for evaluating many people simultaneously, requiring minimal examiner involvement and making them cost-effective for large-scale assessments. However, they lack the personal interaction of individual tests, making it harder to gauge emotional states or unique creative abilities.

🎯 Exam Tip: When describing group tests, emphasize their efficiency and cost-effectiveness for mass assessment, but also note their limitations in capturing individual nuances and creative thinking.

7. Answer the following questions in Detail.

Question 1.Write in detail about the history of intelligence testing.
Answer: Intelligence is the highest attribute of human beings. Different psychologists have defined intelligence differently. Lewis Terman explains intelligence as, “an ability to think on an abstract level." David Wechsler defines intelligence as, 'the aggregate or global capacity of an individual to act purposefully, to think rationally and to deal effectively with his environment'. Many psychologists have contributed to the measurement of Intelligence. Sir Francis Galton thought that he could determine intelligence by measuring the size of the human skull. He administered a battery of tests to measure variables such as head size, reaction time, visual acuity, etc. However, these tests did not prove useful to measure intelligence. Raymond Cattell, used the term 'mental test' for the first time. Like his mentor, Sir Galton, Cattell also believed that intelligence is best measured by sensory tasks. However, be emphasized that test administration must be standardized. In 1905, Alfied Binet in collaboration with Theodor Simon, published the First Scale of Intelligence. This scale was revised in 1908 and 1911. In 1916, Lewis Terman revised the scale, i.e., adapted few items, established new age norms etc. This came to be called 'Stanford Binet Test'. Binet also introduced the concept of Mental Age. It is defined as the age at which the person successfully performs on all items of the test prepared for that age level. In 1917, Robert Yerkes and his colleagues developed the Army Alpha (verbal test) and Army Beta (performance test) intelligence tests. These two tests were used to recruit soldiers. In 1939, during World War II also, to recruit army personnel, the Army General Classification Test was used. In 1939, David Wechsler published the Wechsler-Bellevue Intelligence Test. In 1955 the test was revised and then called Wechsler Adult Intelligence Scale (WAIS). It has a verbal scale and performance scale. Wechsler also developed a test to measure intelligence of children, i.e., Wechsler Intelligence Scale for Children (WISC). Mental Age – Alfred Binet introduced the concept of Mental Age. It is defined as the age at which the person successfully performs on all items of the test prepared for that age level. Mental Age need not correspond to Chronological Age. It Mental Age (MA) is the same as Chronological Age (CA), the person has average intelligence. Intelligence Quotient – In 1912, William Stern introduced the concept of Intelligence Quotient (IQ). Terman, refined the formula for calculating IQ which is as stated below-
\[IQ = \frac{MA}{CA} \times 100\] IQ made it possible to compare the intelligence of individuals of different age CA groups.
In simple words: The history of intelligence testing began with early, flawed attempts by Galton and Cattell focusing on sensory tasks. It truly started with Alfred Binet's 1905 scale, which introduced the concept of Mental Age. Later, Stern developed the IQ formula, and Wechsler created widely used adult and child scales, making intelligence measurement more refined and applicable.

🎯 Exam Tip: Chronologically trace the development of intelligence testing, highlighting the key figures (Galton, Binet, Stern, Terman, Wechsler) and their specific contributions to the field.

Question 2.'Intelligence testing has a wide usage in various areas'. Justify with examples.
Answer: David Wechsler defines intelligence as, 'the aggregate or global capacity of an individual to act purposefully, to think rationally and to deal effectively with his environment.' Types of Intelligence Tests- (i) Individual tests of intelligence- Individual tests of intelligence are tests which can be administered to a single person at a time, for e.g., Stanford Binet Scales, WAIS, Koh's Block Design Test, etc. (ii) Group tests of intelligence- Group test of intelligence are tests that can be administered to more than one person at a time, i.e., for mass testing, for e.g., Army Alpha and Army Beta Test, OTIS self-administrating tests, etc. (iii) Verbal tests of intelligence- Verbal tests of intelligence make use of words and numbers to measure intelligence and subjects respond verbally to the test items, for e.g., WAIS, Army Alpha Test, etc. (vi) Non-verbal tests of intelligence- Non-verbal tests of intelligence do not use language to measure intelligence. They make use of pictures, designs, objects, etc. Such tests may be (i) Performance tests, e.g., Koh's Block Design Test or (ii) Paper-pencil test e.g., Raven's Standard Progressive Matrices. Application of Intelligence Testing 1. Effective Schooling – On the basis of intelligence test scores, teachers can classify students into intellectual categories and devise special instructional programmes suited to their mental development. 2. Aids Mental Health Personnel – Intelligence tests are helpful to Mental Health personnel such as psychologists, etc., for diagnosis purposes and therapy. 3. Effective Parenting – Parents can provide appropriate educational facilities to their children based on their IQ scores. 4. Career Counselling – Scores obtained on intelligence tests help the student to select the right educational options/ courses. 5. Vocational Counselling – Individuals can choose a suitable career and achieve job satisfaction when they make a realistic choice of vocation based on IQ scores.
In simple words: Intelligence testing is widely used across various fields, including education (to tailor teaching methods), mental health (for diagnosis), parenting (to guide educational support), and career counseling (to match individuals with suitable vocations). It provides insights into cognitive strengths, helping individuals make informed choices and achieve better outcomes.

🎯 Exam Tip: Illustrate the broad utility of intelligence testing by providing specific, distinct examples from educational, clinical, and vocational settings.

Question 3.Explain the characteristics of people having high social intelligence.
Answer: E.L. Thorndike proposed the term Social Intelligence. Howard Gardner included 'interpersonal intelligence' in the Multiple Intelligences Theory. According to Karl Albrecht, "Social intelligence is the ability to get along well with others and to get them to cooperate with oneself'. According to Karl Albrecht our behaviour towards others falls somewhere on a spectrum between toxic behaviour and nourishing behaviour. Devaluing others, refusing cooperation to others, negative talking, discouraging others, etc., are some of the examples of toxic behaviours. A continued pattern of toxic behaviour indicates a low level of social intelligence. Respecting others, cooperating with others, positive talking, encouraging others, etc., are some of the examples of nourishing behaviour. A continued pattern of nourishing behaviour indicates a high level of social intelligence. The following are some of the characteristics of people having high social intelligence: 1. They are good at understanding and interacting with other people. 2. They have ability to monitor their verbal and non-verbal expressions while communicating with others. 3. They are good speakers and good listeners. 4. They are skilled at assessing the emotions, motivations, desires, and intentions of those around them. 5. They understand social dynamics in an effective way. 6. They are flexible in their approach while dealing with others. 7. They are goal orientated, persistent and self- confident. 8. They can resolve conflicts in social contexts. 9. They are successful negotiators. 10. They enhance personal and professional relationships with others.
In simple words: People with high social intelligence excel at understanding and interacting with others, displaying strong communication skills, empathy, and an ability to navigate social dynamics effectively. They build positive relationships, resolve conflicts, and inspire cooperation, leading to personal and professional success.

🎯 Exam Tip: List a range of practical, observable characteristics that demonstrate high social intelligence, linking them to positive interpersonal outcomes.

Activity 1Read the following sentences and decide whether the given sentences are the facts or just beliefs about intelligence : (i) Intelligence is something that is inborn. (ii) Students who are intelligent can get good marks in examinations. (iii) Students who do not get good marks in examinations are less intelligent. (iv) People who are intelligent are very smart. (v) Intelligent people can impress anyone by their talk.
Answer:[All the statements are just beliefs, not facts.]
In simple words: The statements are subjective beliefs rather than scientifically proven facts about intelligence, highlighting common misconceptions about how intelligence manifests and its origins. Intelligence is a complex trait, influenced by both genetics and environment, and doesn't solely determine academic or social success.

🎯 Exam Tip: Differentiate between common perceptions/beliefs and scientific facts regarding psychological concepts like intelligence, as this demonstrates critical thinking.

Activity 2 (Textbook Page. No. 15)Read the following examples. Using the formula, calculate the I.Q. of the following students: (i) Aabha is a genius girl. Her chronological age is 8 years and her mental age is 14 years. Find out her I.Q. (ii) Mayur has learning disabilities. His chronological age is 8 years and his mental age is 6 years. Find out his I.Q.
Answer:(i) In case of Aabha – Mental Age (MA) = 14 years Chronological Age (CA) = 8 years, IQ = ?
\[IQ = \frac{MA}{CA} \times 100\]
\[ \implies IQ = \frac{14}{10} \times 100\]
\[ \implies IQ = 175\] IQ = 175.
(ii) In case of Mayur – Mental Age (MA) = 6 years. Chronological Age (CA) = 8 years, IQ = ?
\[IQ = \frac{MA}{CA} \times 100\]
\[ \implies IQ = \frac{6}{10} \times 100\]
\[ \implies IQ = 75\] IQ = 75.
In simple words: Aabha's high Mental Age relative to her Chronological Age gives her a high IQ of 175, indicating above-average intelligence. Conversely, Mayur's lower Mental Age compared to his Chronological Age results in an IQ of 75, suggesting potential learning disabilities.

🎯 Exam Tip: Practice applying the IQ formula accurately, showing each step of the calculation, and interpret the resulting IQ score in context.

Activity 3 (Textbook Page. No. 16)Make a chart listing the advantages and disadvantages of individual tests of intelligence.
Answer:(i) Advantages- 1. The test administrator can establish a rapport with the client. 2.

Activity 8 (Textbook Page. No. 20)

Question. Discuss how the following devices use Artificial Intelligence:
(i) Computers
(ii) Self-driving cars
(iii) Robots
(iv) Medical diagnostic tools
(v) Translation devices
(vi) Automatic Missiles
(vii) Chatbots, etc.
Answer:
(i) Computers - AI is the ability of a computer programme to think and learn. It makes computers smart, i.e., work without being encoded with commands.
(ii) Self-driving cars - Autonomous driving is a key application of AI. Self-driving cars are equipped with multiple sensors such as cameras, radars, etc., which generate massive amount of data and simulate human perceptual and decision making processes in driving.
(iii) Robots - AI gives robots the computer vision to navigate, sense and calculate their reaction accordingly. Robots learn to perform tasks from humans through machine learning which is a part of computer programming and AI.
(iv) Medical diagnostic tools - Abnormalities in body fluids and tissue can be automatically detected using AI in medical diagnosis solutions. AI can help to speed up process of diagnosis, i.e., biomarkers.
(v) Translation devices - AI uses Neural Machine Translation (NMT), i.e., an electronic, neural network trained to recognize patterns in the input data set and translate it into desired output data, for e.g., a sentence in Japanese into English. It is more accurate than simple machine translation.
(vi) Automatic Missiles - AI is leading the world towards a battlefield that has no boundaries, may not even have humans involved and will be impossible to control across the human ecosystem in Cyberspace, Geospace and Space (CGS).
