Variability is a principle of nature. No two individuals are alike. They differ from each other in many respects. Children born of the same parents but they are different and even the-twins are not alike.
Table of Contents
You must have noticed your friends, classmates or relatives, they psychologically differ from each other in the manner they perceive, learn, and think, as also in their performance on various tasks.
This change is seen in physical and mental ( psychological)forms like in height, weight, colour, complexion strength etc., difference in intelligence, achievement, interest, attitude, aptitude, learning habits, motor abilities, skill.
Each individual has an intellectual capacity through which he gains experience and learning.
They have the emotions of love, anger, fear and feelings of pleasure and pain. Everyone has the need of independence, success and need for acceptance.
Broadly individual differences are classified into two categories such as inherited traits and acquired traits.
In this chapter, you will study the nature of intelligence, changing definitions
of intelligence, cultural differences in intelligence, range and variations in
the intellectual competencies of people, and the nature of special abilities and aptitudes.
Causes of Individual Differences:
Learning ability and adjustment capacity naturally grow with people’s age.
One major factor which brings individual differences is education. There are differences in the behaviors of educated and uneducated persons. All traits of human beings like social, emotional and intellectual are controlled and modified through proper education.
Education brings a change in our attitude, behaviour, appreciation, and personality.
Heredity traits bring a change from one individual to another. The entire structure of the body is determined by his heretical qualities.
Intellectual differences of individuals are also to a great extent influenced by hereditary factors.
Environment brings individual differences in various factors like behaviour, activities, attitude, and style of life characteristics. Personality etc.
Environment refers to the different types of people, society, their culture, customs, traditions, social heritage, ideas and ideals.
Nationality is also one of the causes of individual difference, e.g. Indians are very peace loving, Chinese are cruel, Americans are very frank.
Due to sex variation one individual differs from other. Men are considered stronger. But women are better in shouldering social responsibilities and have a better control over their emotions.
Assessment of Psychological Attributes
Assessment is the first step of the measurement of psychological attributes of individuals and their evaluation, often using multiple methods as standards of comparison.
The assessment may be formal or Informal
It is using a defined technique or measuring standards to assess any psychological attribute without letting our own perception change the assessment.
Formal method is objective, standardized and organized.
The formal assessment also involves measurement with respect to its application in a situation.
Informal assessment is based on our perception and assessment of dominance. This type of assessment will vary the results from one assessor to another, depending on their opinions and will be open to subjective interpretation and huge variation.
- It predict future behavior It intervene a change if behaviour is undesirable
- Helps in evaluation of strength and weaknesses of individual
- Helps in assessing personality characteristics
- Helps in recruitment and selection process
Main Domains of Psychological Attributes
Intelligence: It is the capacity to understand, think rationally and use available resources effectively in any situation. It represents general Cognitive ability.
Aptitude: Aptitude assessment helps predict what an individual will be able to do if given proper environment and training, e.g. training a person with good language aptitude can help him become a good writer.
Interest: It’s an individual’s interest to engage in a particular activity. Assessment of interest may help in deciding that in which occupation an individual would be comfortable and happy/satisfied.
Personality: Enduring characteristics that make a person distinct from others.
Values: Enduring Beliefs about an ideal mode of behaviour. It is a set of standard rules, guidelines which a person follows to live his life.
Several methods are used for Psychological assessment.
Psychological Test: It is a standardized test to measure any of the individual’s psychological attributes. E. g. Clinical diagnosis, guidance, personnel selection, placement n training.
Interview: It involves seeking information on a one on one basis by a counsellor from the client.
✍ Case Study: It is a detailed study of a person’s psychological attributes by collecting history, a wide amount of data using interview, observation, and questionnaire of Psychological tests methods.
Observation: This method is useful to study real events, situations however their interpretation can be subjective and in little control of the observer,e g. studying Mother Child relationships by watching them objectively for a certain duration.
Self-report: It’s a method in which an individual provides factual information about himself, opinions, beliefs etc.
Such information can be obtained by Interviews, questionnaires or tests.
Intelligence is the main attribute employed to know how individuals are different from each other.
It is mental alertness, quickness to learn and grasp and ability to understand relationships.
Oxford Definition: Power of Perceiving, Learning, Understanding and Knowing
By renowned psychologists
Alfred Binet: Ability to Judge well, Reason well and Understand well. One similar set of abilities used for solving any or every problem. His theory is called Uni or One factor theory.
Wechsler: Ability to think rationally, act purposefully and to deal effectively with your environment.
Charles Spearman: 1927, proposed a Two Factor Theory. As per him Intelligence consists of a…
- General factors (g- factor) are primary and common to all performances.
- Specific factors (s- factors) which are responsible for specific abilities- Singing, architects, scientists
Louis Thurstone: Intelligence consists of 7 primary abilities, relatively independent. They are:
- Verbal Comprehension ( meaning, words, concepts, ideas)
- Numerical Ability ( speed & accuracy in numerical & computation skills)
- Spatial Relations (Visualising patterns and forms)
- Perceptual Speed (Speed in Perceiving details)
- Word Fluency ( Using words fluently n flexibly)
- Memory (accuracy in recalling information)
- Inductive reasoning ( Deriving rules from presented facts)
Arthur Jensen: Proposed a hierarchical model of intelligence, consisting 2 levels:
- Level 1: Associative learning where Output is more or less similar to Input. ( eg Rote learning & memory)
- Level 2: Cognitive competence. Higher order skills. It transforms the input to produce effective output.
J.P. Guilford: 3 dimensions:
- Operations- Cognition, memory, recording, retention, convergence are the things that the respondent does.
- Contents: Nature of material or information on which intellectual operations are performed. Visual, auditory, symbolic, semantic ( words) , behavioural.
- Products: Form in which information is processed by the respondent.
His theory has 6X5X6 = 180 cells
Theories of Intelligence:
Psychometric Theories of Intelligence
Psychometric theories are based on a model that represents intelligence as a composite of abilities measured by mental tests.
This test model can be quantified. e.g, performance on a number-series test might represent a weighted composite of number, reasoning, and memory abilities for a complex series.
Information Processing Theories
Information processing theory is the approach to the study of cognitive development. This theory is based on the idea that humans process the information they receive, rather than merely responding to stimuli.
Theory Of Multiple Intelligence
According to Howard Gardner Intelligence is not a single entity, rather distinct types of intelligences exist. They are independent of each other but do work together at times to find solutions to a problem.
Gardner studied extremely talented people and found eight types of intelligences:
- Linguistic (Use of language skills): Such people are generally word-smart, articulate, poets & writers.
- Logical-Mathematical (Scientific thinking & Problem solving): This type of people think Logically, critically, abstract reasoning, symbols & mathematical problem solving, effective, e.g, Scientists, mathematicians who won nobel prize.
- Spatial ( Visual images & Patterns): Forming, using, transforming mental images, e.g., Pilots, sailors, sculptors, painters, architects, interior decorators, surgeons.
- Musical ( Sensitivity to rhythm & sound pattern): Produce, create and manipulate music patterns.
- Bodily-Kinaesthetic ( using body flexibly & creatively): Athletes, dancers, sportsmen, gymnasts, surgeons etc.
- Interpersonal (awareness of one’s own feelings, motives & desires): These people use their knowledge about their strengths, limitations and use this awareness effectively to relate to others, e.g., Philosophers, spiritual leaders.
- Naturalists: ( has sensitivity towards the natural world): Awareness of relationship with the natural world. Beauty of flora, fauna, ecology, e.g., Hunters, farmers, tourists, botanists, environmentalists, animal activists.
Triarchic Theory of Intelligence
According to Robert Sternberg (1985), Intelligence is Ability to adapt, to shape and select the environment to accomplish one’s goals and those of society/culture.
Sternberg’s theory comprises three parts:
Componential Analytical subtheory
This form of intelligence focuses on academic proficiency. It is the analysis of information to solve problems. Such people think analytically and critically.
This intelligence has 3 components, each serving different function:
- Knowledge acquisition: Learn, encode, combine & compare information ( Find stage)
- Meta component: Control, evaluate, monitor, plan (cognitive processing- analyse & solve stage)
- Performance components: Action, actually executing the planned task ( Operational skill- transfer stage)
Experiential Creative Subtheory
This intelligence focuses on capacity to be intellectually flexible and innovative. Such people use past experiences creatively to solve new problems. They make new inventions and discoveries, also they have the ability to filter crucial information for a given situation.
Practical Contextual Subtheory
This intelligence involves the ability to deal with environmental demands. Such people adapt to the environment or modify the environment as per their needs and hence are more successful, e.g. When the weather changes and temperatures drop, people adapt by wearing extra layers of clothing to remain warm.
Planning, Attention-Arousal andSimultaneous Successive Model of Intelligence
The Planning, Attention-Arousal, Simultaneous and Successive (PASS) theory of intelligence, was elaborated by Das, Naglieri & Kirby (1994)
It is an essential part of intelligence. After the information is attended to and processed, planning is activated.
It allows us to think of possible courses of action that need to be implemented to reach the target and evaluate their effectiveness.
In case the plan doesn’t work this part of intelligence also helps review the gaps and device alternate plan.
Arousal helps in paying attention to the stimuli. Too much or too little arousal will interfere with the attention.
E.g Teacher informs you about the upcoming test, which stimulates you to attend the chapters. Arousal helps you in focusing your attention on reading, learning, revising.
Simultaneous & successive progressing:
Simultaneous processing allows you to perceive the relationship between various concepts and integrate them into meaningful patterns. Relationship among abstract figures, e.g. Solving Jigsaw puzzles.
Successive processing takes place when you remember things sequentially, e.g. Learning digits, alphabets etc.
Individual Differences in Intelligence
The study conducted on Identical twins brought up together or in different environment helps us establish the fact that the factors that influence intelligence are:
- Nature- Heredity, genes
- Nurture- Environment, nutrition
Research showed: Correlation of Intelligence of different samples are as follows:
- Identical Twins reared together correlate almost 0.9
- Identical twins, separated in childhood correlate 0.72
- Fraternal twins reared together correlate 0.6
- Siblings reared together correlate 0.5
- Siblings reared apart correlate about 0.25
- Adopted children display intelligence more similar to biological parents than adoptive ones.
Hence, Intelligence is a product of complex interaction of heredity (Nature) and environment (Nurture).
Assessment of Intelligence:
In 1905, Alfred Binet and Theodore Simon made the first successful attempt to measure intelligence.
MA- Mental Age- It’s a measure of intellectual development relative to people of the same age.
CA- Chronological Age- Biological age from birth.
If MA is higher than CA, the person is considered bright and more intelligent.
If MA=CA , then it is considered average intelligence.
If MA<CA, The person is called retarded as per Binet and Simon.
Intelligence Quotient: 1912, William Stern, German Psychologist: IQ
IQ= Mental Age divided by Chronological age and Multiplied by 100.
IQ= MA/CA X100
100 is the multiplier to avoid value in decimals.
So if MA=CA, IQ is 100
For a value more then 100, it means the child’s mental age is higher by those points than chronological age. And for values less than 100, considered low IQ.
Usually distribution over the population follows a bell curve.
|Above 130||Very superior||2.2|
Culture And Intelligence
Cultural and intellectual or cultural Intelligence (CQ) is the ability to recognize and adapt to cultural differences. It can give you the confidence to operate successfully in a wide range of settings.
Culture not only refers to nationality, ethnicity or religion. It also apply to social groups, business organizations, and the departments, age groups and teams within them.
CQ combines head (knowledge and understanding), body (actions), and heart (confidence and commitment).
According to author Dr David Livermore, culturally intelligent people exhibit:
- CQ Drive: The motivation to learn about new cultures.
- CQ Knowledge: Understanding how cultures influence what people say and do.
- CQ Strategy: Having a plan to respond to cultural differences.
- CQ Action: Behaving in culturally-sensitive ways, including handling any difficulties that arise.
Emotional intelligence also known as emotional quotient or EQ) is the ability to understand, use, and manage your own emotions in positive ways to relieve stress, communicate effectively, empathize with others, overcome challenges and defuse conflict.
Emotional intelligence helps you succeed at school and work, achieve your career and personal goals and build stronger relationships,
It also help you to connect with your feelings, turn intention into action, and make informed decisions about what matters most to you.
Emotional intelligence affects your performance at school or work, your physical and mental health, your relationships and your social intelligence.
Emotional intelligence has four attributes:
- Self-management : You can manage your emotions in healthy ways, take initiative, follow through on commitments, adapt to changing circumstances and able to control impulsive feelings and behaviors,
- Self-awareness: You recognize your own strengths and weaknesses, and have self-confidence. You also recognize your own emotions and how they affect your thoughts and behavior.
- Social awareness: You can understand the emotions, needs, and concerns of other people.
- Relationship management: You know how to develop good relationships, communicate clearly, inspire and influence others, work well in a team, and manage conflict.
Aptitude: Nature and Measurement
Aptitude is the special ability which is confined to the potentialities for the future. It helps to predict the probable development of certain abilities.
An aptitude is a combination of in-born capacities and developed abilities. Such combinations of inborn capacities and developed abilities make the person what he is at any given time and predicts what he may become.
Warren: “An aptitude is a condition or set of characteristics regarded as symptomatic of an individual’s ability to acquire with training some knowledge and skill onset of responses such as the ability to speak a language or to practice music etc.”
Nature of Aptitude
- An aptitude is a combination of abilities and personality characteristics which lead a person to do one kind of work better than another and increases his chances of success at it.
- An aptitude is not an ordinary trait of human personality.
- An aptitude is largely acquired though in many cases. It is inborn in nature.
Measurement of Aptitude:
A number of aptitude tests have been developed.
Aptitude tests can be broadly categorised under two heads
(i) Differential Aptitude Test Battery, and
(ii) Special Aptitude tests.
Differential Aptitude Test Battery:
This is a comprehensive and carefully developed Battery developed by George K. Bennett, Harold G. Seashore and Alexander G. Wesman.
It was developed mainly for use in educational and vocational counseling of high school students.
- Verbal reasoning test,Numerical ability test,
- Abstract reasoning test,
- Space relations tests,
- Mechanical reasoning test,
- Clerical speed and accuracy test, and
- Language usage test.
Special Aptitude Tests:
1. Mechanical Aptitude Test:
Mechanical ability is an ability involved in manipulating concrete objects, such as tools, and in dealing mentally with mechanical movements.
A number of tests are available for measuring mechanical aptitude for a large field of occupations.
- Minnesota Mechanical Assembly Test.
- Minnesota Spatial Relations Test.
- Minnesota Paper Form Board.
- Johnson O’Connor’s Wiggly Blocks.
- Sharma’s Mechanical Aptitude Test Battery.
- Stenquist Mechanical Aptitude Tests.
2. Clerical Aptitude Tests:
Clerical duties include the gathering, classification, and presentation of data of all sorts, and analysis and use of these data in planning, executing and determining the results of operation.
A number of tests are available for measuring clerical aptitude:
- Minnesota Clerical Aptitude Test.
- General Clerical Aptitude.
- The Detroit Clerical Aptitude Examination.
- P.R.W. Test.
- Orissa Test of Clerical Aptitude.
- Clerical Aptitude Test.
3. Tests of Artistic Aptitude:
Some tests have been designed to measure artistic aptitudes.
Graphic Arts Test: These tests measure the art and aesthetic aptitudes.
Musical Aptitude Tests: These tests measure the various components of musical talent.
Literary Aptitude Tests: Some examples of such tests are Abbot Traube Test, Rigg Poetry Judgement Test.
Professional Aptitude Tests: These tests measure aptitude for different professions. Such tests are conducted before admission into professional institutions like medical, legal, engineering institutions.
There are many tests available to measure aptitude in medicine, science, mathematics, law, engineering, teaching etc.
Scholastic Aptitude Tests: These tests measure scholastic or academic aptitudes. Some examples of such tests are Scholastic Aptitude Tests of C.E.E. Board, Graduate Record Examination.
Other Tests like Motor Dexterity Tests:
Other Tests like Motor Dexterity Tests, Sensory Tests, Visual Tests and Auditory Tests.
Creativity is a phenomenon where something new and valuable is formed. The created item may be intangible (such as an idea, a scientific theory, a musical composition or a joke) tangible or a physical object (such as an invention, a literary work or a painting).
There are many differences in the potential for creativity across individuals and the manner in which creativity is expressed.
Creativity can be expressed in writing, dance, poetry, science and so on.
Display of creativity can be seen in a poem, painting, new chemical process, an innovation of law, a breakthrough in science in preventing a disease.
Some names of highly creative persons in history are: Tagore, Einstein, C.V.Raman, Ramanujan etc. for their outstanding contribution.
The definition of creativity has broadened and it includes ordinary people in creative occupations like Pottery, carpentry, cooking etc.
Creativity and Intelligence:
Intelligence is a brain function which helps individuals to perform and excel in multiple domains. Creativity is the ability to use this intelligence in order to create something unique and novel in a specific field.
The relationship between Intelligence and creativity is high. All kinds of creative abilities require a minimum level of intelligence to acquire knowledge, capacity to comprehend, retain and retrieve.
For instance, to express creativity in writing, one must possess adequate language skills and to express creativity in creating new laws of science, one must have intelligence to acquire basic knowledge of the subject.
Creativity tests are open ended and involve making a person think of different answers to the questions and problems.
They give freedom to individuals to go in different directions and freedom to use their imagination and express themselves in original ways.
Textbook Exercises With Answers
Q.1. How do psychologists characterize and define intelligence ?
Ans. (i) Generally intelligence is a key construct employed to know how individuals differ from one another. It also provides an understanding of how people adapt their behavior according to the environment they live in. We see a person’s mental alertness, ready wit, quickness in learning and ability to understand relationships.
(ii) Oxford Dictionary explains intelligence as the power of perceiving, learning, understanding and knowing.
(iii) The psychologists, on the other hand, have defined intelligence in a different way as mentioned below:
(a) Early intelligence theorist Alfred Binct defined intelligence as the ability to judge well, understand well and reason well.
(b) Wechsler defined intelligence in terms of its functionality. He defined it as the global and aggregate capacity of an individual to think rationally, act purposefully, and to deal effectively with his/her environment.
(c) Gardner and Sternberg have suggested that an intelligent individual not only adapts to the environment, but also actively modifies or shapes it.
Q.2. To what extent is our intelligence the result of heredity (nature) and environment (nurture) ? Discuss.
Ans. Our intelligence is a result of heredity (nature) and environment (nurture) comes from studies on twins and adopted children.
(A) The role of nature and nurture as regards correlation are found as mentioned below
(i) The intelligence of identical twins reared together correlates 0.90.
(ii) Twins separated early in childhood show considerable similarity.
(ii) The intelligence of identical twins reared in different environments correlate 0.72.
(iv) Fraternal twins reared together correlate almost 0.60.
(v) Brothers and sisters reared together correlate about 0.50.
(vi) Siblings reared apart correlate about 0.25.
(vii) In case of adopted children, children’s intelligence is more similar to their biological rather than adoptive parents.
(B) Role of environment relating intelligence is as mentioned below
(i) As children grow in age, their intelligence level tends to move closer to that of their adoptive parents
(ii) Children from disadvantaged homes adopted into families with higher socio-economic status exhibit a large increase in their intelligence scores.
(iii) Environmental deprivation lowers intelligence while rich nutrition, good family background, schooling increases intelligence.
(iv) There is general consensus among psychologists that intelligence is a product of complex interaction of heredity and environment. Heredity sets a range within which an individual’s development is actually shaped by the support and opportunities of the environment.
Q.3. Explain briefly the multiple intelligences identified by Gardner. [CBSE 2008]
Ans. (A) The main features of Gardner’s theory of multiple intelligences are as mentioned below:
(i)There are distinct types of intelligence.
(ii) Each of the intelligences are independent of each other.
(iii) Different types of intelligences interact and work together to find a solution to a problem.
(B) According to Gardner, there are eight types of intelligences as mentioned below:
(i) Linguistic i.e., skills involved in the production and use of language. It is the capacity to use language fluently. Such people are ‘word-smart’. Poets and writers come in this category.
(ii) Logical-Mathematical i.e., skills in scientific thinking and problem solving. Such persons can be examples of this category. They think logically and critically. They can solve mathematical problems. Scientists and Nobel Prize winners are example of this category
(iii) Spatial i.e., skills in forming visual images and patterns. Pilots, sailors, sculptors, painters, architects, interior decorators and surgeons have highly developed spatial intelligence.
(iv) Musical i.e., sensitivity to musical rhythms and patterns. Such persons are very sensitive to sounds and vibrations, and in creating new patterns of sounds.
(v) Bodily-Kinaesthetic i.e., using whole or portions of the body flexibly and creatively. Athletes, dancers, actors, sportspersons, gymnasts and surgeons have this type of intelligence.
(vi) Interpersonal i.e., sensitivity to subtle aspects of others’ behaviors. It relates to understanding the motives, feelings and behaviors of other people in order to have a comfortable relationship with them.
Psychologists, counselors, politicians, social workers, possess interpersonal intelligence.
(vii) Intrapersonal i.e., awareness of one’s own feelings, motives and desires. It is about
knowledge of one’s internal strengths and limitations. The persons who have such intelligence are philosophers and spiritual leaders.
(viii) Naturalistic i.e., sensitivity to the features of the natural world. It helps in recognising the beauty of flora and fauna. Hunters, farmers, tourists, botanists, zoologists, and bird watchers possess this intelligence.
Q.4. How does triarchic theory help us to understand intelligence ? [CBSE 2012, 2013]
Ans. Robert Sternberg proposed this theory. He defined intelligence as “the ability to adapt, to shape and select the environment to accomplish one’s goals and those of one’s society and culture”.
According to this theory, there are three basic types of intelligence: Componential, Experiential, and Contextual as explained below:
(i) Componential subtheory specifies the cognitive processes that underlines all intelligent behavior. It has three components:
(a) Knowledge acquisition components encode, combine and compare information.
(b) Meta components control, monitor and evaluate cognitive processing.
(c) Performance components execute strategies assembled by meta components.
(ii) Experiential Intelligence is involved in using past experiences creatively to solve novel problems.
(iii) Contextual Intelligence involves the ability to deal with environmental demands encountered on a daily basis. It may be called ‘street smartness’ or ‘business sense’. This quality makes people successful in life.
Q.5. “Any intellectual activity involves the independent functioning of three neurological systems.” Explain with reference to the PASS model.
Ans. The PASS model has been developed by J.P. Das, Jack Naglieri, and Kirby. According to this model, any intellectual activity involves the interdependent functioning of three neurological systems called the functional units of the brain. These are responsible for arousal/attention, simultaneous and successive processing, and planning respectively.
(a) State of arousal is basic to any behavior.
(b) It enables a person to process information.
(c) An optimal level of arousal focuses our attention to the relevant aspects of a problem. For example, in case of a class test, arousal forces the student to focus his attention on reading, learning and revising the contents of the prescribed chapters.
(ii) Simultaneous and Successive Processing: Information can be integrated into your knowledge system simultaneously or successively:
(a) Simultaneous processing relates to perceiving the relations among various concepts and integrating them into a meaningful pattern for comprehension. The example is Raven’s Progressive Matrices (RPM) Test.
(b) Successive processing relates to recalling information serially so that recall of one leads to the recall of another. Learning multiplication tables is an example.
(iii) Planning: It allows us to think of the possible courses of action, implement them to reach a target, and evaluate their effectiveness.
A plan can be modified to suit the situation. For example, one prepares a time schedule to prepare for a test. The time schedule can be changed due to any function in the family.
Q.6. Are there cultural differences in the conceptualisation of intelligence ?
(i) Culture plays a role in the conceptualisation of intelligence. The cultural environment provides a context for intelligence to develop. According to Sternburg intelligence is a product of culture.
Elementary mental functions e.gCrying, walking etc. are universal but higher mental functions such as problem solving are largely culture-produced.
(ii) In technologically advanced societies there is technological intelligence i.e.. persons are well-versed in the skill of attention, observation, analysis, performance.
Intelligence tests developed in western cultures look precisely for these skills in an individual. On the other hand, technological intelligence is not so valued in many Asian and African countries.
(iii) Integral intelligence as in the Indian tradition, gives emphasis on connectivity with the social and world environment. In India, the Sanskrit word ‘buddhi’ represents intelligence.
Buddhi includes such skills as mental effort, determined action, feelings and understanding. Buddhi is the knowledge of one’s own self based on conscience, will and desire. Buddhi includes the competencies as mentioned below.
• Cognitive capacity i.e., understanding, problem solving and effective communication.
• Social competence i.e., respect for social order and commitment to elders, the young and the needy.
• Emotional competence L.e., self-regulation and self-monitoring of emotions.
• Entrepreneurial competence i.e., commitment, patience and hard work.
Q.7. What is IQ ? How do psychologists classify people on the basis of their IQ scores
Ans. (a) IQ refers to mental age divided by chronological age and multiplied by 100.
IQ = ΜΑ/CA × 100
|Above 130||Very superior||2.2|
(b) Classification of people on the basis of IQ is as in the table given below
Q.8.How can you differentiate between verbal and performance tests of intelligence?
Ans. An intelligence test may be fully verbal, fully non-verbal or fully performance based or it may consist of a mixture of items from each category.
(a) Verbal tests:
(i) These tests require subjects to give verbal responses either orally or in a written form.
(ii) These can be administered to literate people.
(b) Performance Tests: These require subjects to manipulate objects and other materials to pendem a task. For example, Kohs’ Block Design Test contains a number of wooden blocks. The subject is asked to arrange blocks within a time limit to produce a given design.
Q.9. All persons do not have the same intellectual capacity. How do individuals vary in their intellectual ability ? Explain.
Ans. It is correct to say that all persons do not have the same intellectual capacity as mentioned below:
(i) Some are exceptionally bright.
(ii) Some are below average.
(iii) About 2 per cent of the population have IQ above 130. They are called intellectually gifted.
(iv) A similar percentage have IQ below 70. These are termed intellectually disabled.
(v) The above two groups i.e.. intellectually gifted and intellectually disabled deviate considerably from the normal population in respect of their cognitive, emotional and motivational characteristics.
Q.10. Which of the two, IQ or EQ, do you think would be more related to success in life and why?
Ans. Intelligence Quotient (IQ) is a value that indicates a person’s ability to learn, understand and apply information and skills in a meaningful way. On the other hand, Emotional Quotient (EQ) or Emotional Intelligence is a set of skills that underlie accurate appraisal expression, and regulation of emotions. It is the feeling side of intelligence. EQ is a good predictor of success.
A good IQ and scholastic record is not enough to be successful in life. There are people who are academically talented but are unsuccessful in their own life. They experience problems in family, workplace and interpersonal relationships due to lack of emotional intelligence. That is why emotional
Intelligence is receiving increasing attention from educators for dealing with students who are affected by stresses and challenges of the outside world.
Thus EQ would be more related to success in life.
Q.11. How is ‘aptitude’ different from ‘interest’ and ‘intelligence’? How is aptitude measured?
Ans. (A) (i) Aptitude refers to special abilities in a particular field of activity. It is a combination of characteristics that indicates an individual’s capacity to acquire some specific knowledge or skill after training. It helps to predict an individual’s future performance.
(ii) Interest is a preference for a particular activity and aptitude is the potentiality to perform that activity. Thus, a student with high mechanical aptitude and strong interest in engineering is more likely to be a successful mechanical engineer.
(iii) Intelligence is the global and aggregate capacity of an individual to think rationally, act purposefully, and to deal effectively with his/her environment.
(B) Aptitude is measured/assessed with the help of selected tests.
Q.12. How is creativity related to intelligence?
Ans. (i) Creativity is the ability to produce ideas, objects or problem solutions that are novel, appropriate and useful.
(ii) Certain level of intelligence is necessary to be creative, but a high level of intelligence, however does not ensure that a person would certainly be creative.
(iii) Researchers have also found that both high and low levels of creativity can be found in highly intelligent children and also children of average intelligence.
