Question & Answer
Q.1: How do psychologists characterise and define intelligence?
Ans : Psychological motion of intelligence is quite different from the common sensed motion of intelligence. Generally people saw intelligence as mental alertness. ready art, quickness in learning and ability to understand relationships. Oxford dictionary explained intelligence as the power of perceiving, learning understanding and knowing. Accordingly Alfred Binet also used these attributes and defined intelligence as ability to judge well. understand well and reason well Later Wechsler gave a comprehensive definition in terms of its functionality i.e.. its value for adaptation to environment, He defined intelligence as •the global and aggregate capacity of an individual to think rationally. act purposefully and to deal effectively with his/her environment: Present day psychologists such as Gardner and Sternberg emphasized that. •Intelligent individual not only adapts to the environment. but actively modifies or shapes it. •Sternberg views intelligence as the ability to adapt, to shape and select environment to accomplish cnes Goals and those of ones society and culture.
Q.2: To what extent is our intelligence the result of heredity (nature) and environment (nurture)? Discuss.
Ans : (i) Whether intelligence is evolved or it is developed due to the environment. is a question of debate. (ii)Lot of studies have been done to determine the role of nature and nurture. (iii)Here we will discuss the controversy with the help of various twin studies. adoption studies and environmental studies. On the basis of twin studies co-relation results are as follows: (i)ldentical twins reared together correlate 0.90 (ii)ldentical twins reported early in childhood and reared in different environments correlate 0.72 (iii)Fraternal twins reared together correlate 0.60 (iv)Siblings reared together correlate 0.50 (v) Siblings reared apart correlate 0.25 •Adoption Studies before Age Of 6-7 Years These studies of adopted children show that children's intelligence is more similar to their biological parents. These studies provide evidence that intelligence is determined because of nature. •Adoption Studies after the Age Of 6-7 Years According to these studies as children grew older tends to more closer to that of their adoptive parents. Environmental Studies Evidence for the influence of environment (Nature) on the basis Of Twin Studies. (i) The intelligence score of twins reared apart as they grew older, tends to more closer to that of their adoptive parents. (ii)On the basis of differences in environment, children from disadvantaged homes adopted into families with higher, socio-economic status exhibit an increase in their intelligence scores. (iii)EnvironmentaI deprivation lowers intelligence. Factors such as nutrition, good family background and quality schooling increase growth rate of intelligence, (iv)There is general consensus among psychologists that intelligence is a product of complex interaction of heredity (Nature) and environment (Nurture). (v)Heredity provides the potentials and sets a range of growth whereas environment facilitates the development of intelligence.
Q.3: Explain briefly the multiple intelligences identified by Gardner.
Ans : Gardner’s theory based on information processing approaches functions on three basic principles: (i)lntelligence is not a single entity, there exist multiple intelligences. (ii)The intelligences are independent from each other (iii)Different types of intelligences work together to provide a solution of problem. Gardner has so far proposed eight intelligences, however all individuals do not possess them in equal proportion. The particular situation or the context decides the prominence of one type of intelligence over the others. Following are the eight types of intelligence: 1.Linguistic: This is related to reading, writing, listening, talking, understanding etc. Poets exhibit this ability better than others, 2.Logical-Mathematical: This type of intelligence deals with abstract reasoning and manipulation of symbols involved in numerical problems. It is exhibited in scientific work, 3.Spatial: This type of intelligence is involved in perceiving third dimension formation of images, It is used while navigating in space, forming, transforming and using mental images. Sailors, engineers, surgeons, pilots, care drivers, sculptors and painters have highly developed spatial intelligence. 4.Musical: Persons with musical intelligence show sensitivity to pitch and tone required for singing, playing and instrument, composing and appreciating music etc. 5B0dily Kinesthetic: It requires the skills and dexterity for fine coordinated motor movements, such as those required for dancing, athletics, surgery, craft making etc. 6.1ntepersonal: It requires understanding of motives, feelings and behaviours of other peoplesales people, politicians, teachers, clinicians and religious readers have high degree of interpersonal intelligence,7. Intra-p«sonal: It is related to understanding one's self and developing a sense of identity, e.g., philosophers and spiritual leaders. 8.Naturalistic: It is related to recognizing the flora and fauna, i.e., natural world and making a distinction in the natural world. It is more possessed by hunters, farmers, tourists, students of biological sciences etc.
Q.4: How does the triarchic theory help us to understand intelligence?
Ans : 1. Robert J. Stemberg proposes a theory of intelligence based on information processing approach in 1985 known as the Triarchic theory of intelligence 2. According to Sternberg. intelligence is an ability to adapt. to shape and select environment to accomplish ones goals and those of ones society and culture. 3, This theory attempts to understand the cognitive processes involved in problem solving. 4. According to him there are three types of intelligences: (i)Componential intelligence (Analytical): This dimension specifies the cognitive processes that underlie an intelligent behaviour. This dimension serves three different functions: (a)Knowledge acquisition component.• These are the processes used in learning, encoding, combining and comparing information. (b)Metacornponents.• 'Meta' means higher. These are executive processes. They control monitor and evaluate cognitive processing. (c)Performance compments: These components execute strategies prepared by metacomponents to perform a task for example. While studying students plan the lesson chapterwise. they make schedules. categories the learning material and do integrate the information to comprehend well. (ii)Experiential intelligence (Creative): This dimension specifies how experiences effect intelligence and how intelligence effects a person's experiences. (a)Experiential intelligence refers to an individual's ability to make use of one's past experiences to deal with novel situations creatively and effectively.(b)This intelligence is mostly high among scientists and creative people. (c) For example if a person is trapped in a room. he finds out a way of coming out of the room using rope or ladder etc. in a creative way. He had some knowledge of getting out from this situation by watching out a movie few years back (iii)Contextual intelligelce (Practical): This dimension specifies the ability to deal with environmental demands on daily basis. (a)lt is individual's ability to make use of his/her potential to deal with day-to-day life. (b)lt may tk called street smartness or business sense'. (c)People high in this ability are successful in life. •It deals with the ways people handle effectively their environmental demands and adapt to different contexts with available resources.
Q.5: “Any intellectual activity involves the independent functioning of three neurological systems”. Explain with reference to PASS model.
Ans : According to PASS model, theory based on information processing approach, intellectual activity involves the interdependent functioning of the three neurological systems called the functional units of the brain. These units are responsible for: •the arousal and attention. • the simultaneous and successive processing. •the planning. Arousal and Attention (i)State of arousal helps in attending to the stimuli. (ii)ArousaI and attention enable a person to process information. (iii)Optimal level of arousal focuses our attention on relevant aspects of a problem. (iv)Too much or too little arousal interferes with attention and performance. Example: Arousal helps the individual to focus ones attention on reading, learning and revising the contents of the material to be learnt. Simultaneous and Successive Processing: Simultaneous Processing refers to perceiving relations amongst various concepts and integrate them into meaningful patterns for comprehension! For e.g.. in Raven's standard progressive matrices (RSPM Test) choosing appropriate pattern by comprehending relationship. Successive Processing refers to recalling information serially so that one recall leads to another recall. For example. leaming of digits and letters and multiplication tables 1 After the information is attended to and processed. planning is activated. 2_Planning involves reaching to the target and evaluating their effectiveness. Planning allows us to think of possible courses of action and implementing them. 31f a plan does not work. it is modified to suit the requirements of the task or the situation 4For example. to take a test scheduled by your teacher. you'd have to set goals. plan a time schedule of studies. get clarifications in case of problems or think of other ways to meet your goals.
