Malins Intelligence Scale For Indian Children (MISIC)

AIM :

To assess the verbal intelligence of an individual using Malins Intelligence Scale For Indian Children (MISIC).

INTRODUCTION :

The word intelligence derives from the Latin word intelligere which means to comprehend or to perceive it is the most basic meaning of intelligence.

Intelligence is a bunch of different abilities like -understanding novel stimuli, learning, language, and communication, being aware of the environment, the ability to reason, plan and solve problems creatively.

Aptitude refers to an individual’s underlying potential for acquiring skills. Aptitude tests are used to predict what an individual will be able to do if given proper environment and training. A person with high mechanical aptitude can profit from appropriate training and can do well as an engineer. Similarly, a person having high language aptitude can be trained to be a good writer.

Interest is an individual’s preference for engaging in one or more specific activities relative to others. Assessment of interests of students may help to decide what subjects or courses they can pursue comfortably and with pleasure. Knowledge of interests helps us in making choices that promote life satisfaction and performance on jobs.

Definitions of intelligence

American Psychological Association (APA) refers to intelligence as intellectual functioning.

Albert Binet defined intelligence as “The ability to judge well, to understand well, to reason well”.

“Intelligence is the capacity to form concepts and to grasp their significance(Terman 1916).

According to David Wechsler (1944), “Intelligence is the aggregate or global capacity of the individual to act purposefully, to think rationally and to deal effectively with the environment.” 

Sternberg and Kaufman (2011) defined intelligence is, “one’s ability to learn, think and to adapt to the environment”.

Initially they were more stressing intelligence as an ability or general mental ability but now Most of the psychologist agreed that adaptation to the environment is the key to understanding both what intelligence is and what it does.

Intelligence: Interplay of Nature and Nurture

The evidence for hereditary influences on intelligence comes mainly from studies on twins and adopted children. The intelligence of identical twins reared together correlate almost 0.90. Twins separated early in childhood also show considerable similarity in their intellectual, personality and behavioural characteristics. The intelligence of identical twins reared in different environments correlate 0.72, those of fraternal twins reared together correlate almost 0.60, and those of brothers and sisters reared together correlate about 0.50, while siblings reared apart correlate about 0.25. Another line of evidence comes from the studies of adopted children, which show that children’s intelligence is more similar to their biological rather than adoptive parents. With respect to the role of environment, studies have reported that as children grow in age, their intelligence level tends to move closer to that of their adoptive parents. Children from disadvantaged homes adopted into families with higher socioeconomic status exhibit a large increase in their intelligence scores. There is evidence that environmental deprivation lowers intelligence while rich nutrition, good family background, and quality schooling increases intelligence. There is a general consensus among psychologists that intelligence is a product of complex interaction of heredity (nature) and environment (nurture). Heredity can best be viewed as something that sets a range within which an individual’s development is actually shaped by the support and opportunities of the environment.

Assessment of Intelligence :

In 1905, Alfred Binet and Theodore Simon, made the first successful attempt to formally measure intelligence. In 1908, when the scale was revised, they gave the concept of Mental Age (MA), which is a measure of a person’s intellectual development relative to people of her/his age group. A mental age of 5 means that a child’s performance on an intelligence test equals the average performance level of a group of 5-year olds. Chronological Age (CA) is the biological age from birth. A bright child’s MA is more than her/his CA; for a dull child, MA is below the CA. Retardation was defined by Binet and Simon as being two mental age years below the chronological age. In 1912, William Stern, a German psychologist, devised the concept of Intelligence Quotient (IQ). IQ refers to mental age divided by chronological age, and multiplied by 100.

IQ = (MA/CA) x 100

Types of Intelligence Tests :

Intelligence tests are of several types. On the basis of their administration procedure, they can be categorised as individual or group tests. They can also be classified as either verbal or performance tests on the basis of the nature of items used. Depending upon the extent to which an intelligence test favours one culture over another, it can be judged as either culturefair or culture-biased. You can choose a test depending on the purpose of your use.

Improving our intelligence:

Intelligence is not a set trait but it is a changeable, flexible ability to learn and stimulate the brain that can improve over time.  Practicing certain lifestyle habits may help improve one’s overall intelligence, which includes two types which are crystallized intelligence which is associated with intellectual skill development and fluid intelligence which is associated with abstract reasoning. An individual can improve various areas of intelligence through:

  1. Memory activities:

It can help to improve memory, reasoning and language skills. Memory games have been used in research studies to explore how memory relates to language and object knowledge. Activities that involve memory training include:

  • Jigsaw puzzles
  • Crossword puzzles
  • Concentration card game, or card matching
  • Sudoku
  • Executive control activities:

Executive control is the ability to control complex cognitive activities. It is a part of executive function which also includes executive management and regulation. Research suggests that executive function is strongly tied to fluid reasoning, one aspect of human intelligence. Activities that involve executive control training include:

  • Scrabble
  • Pictionary
  • Red light, green light
  • Brainteasers
  • Visuospatial reasoning activities:

It involves the mental processes related to physical representations. In one study, researchers found that improving visuospatial reasoning led to an increase in IQ test scores. In that study, memory and executive control activities were used in part to help improve participant’s visuospatial reasoning. Activities that involve visual and spatial training include:

  • Mazes
  • Point-of-view activities
  • 3 – D models
  • Unfolded prisms

Some Misuses of Intelligence Tests:

Unless used by a trained investigator, they may be misused either intentionally or unintentionally. Some of the illeffects of intelligence testing by naive testers are:

  • Poor performance on a test may attach a stigma to children and thereby adversely affect their performance and self-respect.
  • The tests may invite discriminating practices from parents, teachers and elders in the society.
  • Administering a test biased in favour of the middle class and higher class populations may underestimate the IQ of children coming from disadvantaged sections of the society.
  • Intelligence tests do not capture creative potentialities and practical side of intelligence, and they also do not relate much to success in life. Intelligence can be a potential factor for achievement in various spheres of life.

It is suggested that one should guard against erroneous practices associated with intelligence tests and take the help of trained psychologists to analyse an individual’s strengths and weaknesses.

MALINS INTELLIGENCE SCALE FOR INDIAN CHILDREN (MISIC) :

Malin’s has been adapted from the American test WISC developed by Dr. David Wechsler.

The Indian Scale has been constructed by Dr Arthur J. Malin of Nagpur. During adaptation, an almost total revision had to be made of the test, especially of the culturally biased verbal items. So the test was named as Intelligence Scale for Indian Children- ISIC or MISIC. English is the only language that applies universally through India; hence WISC has adapted in English for English Speaking children in India. Later it was also adapted in Hindi and Marathi as India is a country dominated by many regional languages.

MISC is an intelligence test for children from the ages of 6 to 15 years 11 months. It is administered individually and takes about 2 to 2-1/2 hours. The test comprises of 12 subtests divided into two groups, Verbal and Performance. Verbal Scale consists of 6 subtests and Performance Scale consists of 5 subtests.

VERBAL SCALE

  1. Information Test: The test consists of questions about factual knowledge of persons, places, and common phenomena. It has total of 30 questions. Questions 1-5 are used for children below 8 years old or suspected mental defects. Each item is scored 1 or 0. The subject above 8 years is given credits for question  1-5 directly, if the subject passes items 6,7 & 8. Discontinue the test after 5 consecutive failures. Examples- How many ears you have?
  2. General Comprehension Test: The test consists of questions about certain practices and behavior under certain situations. It measures conventional knowledge and knowledge of social appropriateness. It has total 14 questions. The test is discontinued after 3 consecutive failures.

Each item is scored from 0-2. Items 1-5 are scored 2 points if the subject takes personal responsibility; and 1 point if the subjects knows what is to be done, but the responsibility is shirked away. For item 6-14,  2 points are given when the subject gives 2 good reasons , and 1 point when the subject gives one reason.

Example- What should you do if you cut your finger?

  • Arithmetic Test– The test consists of questions based on a simple mathematical calculation which are solved mentally. Problems 1-3 are for the subjects below 8 years or suspected mental defectives. Discontinue after 3 consecutive failures.

Each item is scored 1 or 0. Credit is given to the subject for the first 3 items if the subject above 8 years solves the item 4 and 5 correctly.

Example- if I break this pencil in half, how many pieces there will be?

  • Analogy & Similarity test–

Analogy: The test consists of 4 incomplete sentences based on analogies that the subject has to complete. The test is for subjects below 8 years old. Each correct analogy is given a score of 2.

Example- Lemon is sour, but sugar is……….

Similarity– The test consists of questions where the subject has to find the similarity between the two things. It measures verbal concept formation. This test is for subjects above 8 years. Discontinue the test after 3 consecutive failures or return to the analogy. Each item is scored from 0-2, depending on the answer. If the subject answers the 3 items correctly in similarity, the subject is given the credit for 4 analogies.

  • Vocabulary Test– The test consists of the question that measures the subject’s general intelligence. It reflects the subject’s breadth of experience and ideas developed over the years. The test has 40 items. Discontinue the test after 5 consecutive failures.

Each item is scored from 0 to 2. Except item 1-6 which are scored as 0 or 2. Subject can start directly from 10th item. The subject is credited 2 points directly for the previous 9 items if he/she gives 2 point definition for 10th– 14th items.

Example- cycle, shoe, etc.

  • Digit Span Test– In this test the subject is told a sequence of number verbally. The subject is supposed to repeat the number in the same order. The test is divided into 2 types. They are:

Digit Span Forward- the digits are repeated as they are called out.

Digit Span Backward- the digits are repeated in the reverse order.

The score of the test is the highest number of digits repeated without error, both forward and backward digits together.

PERFORMANCE SCALE

  1. Picture Completion Test– The test consists of twenty pictures in which some part of each picture is missing. The subject is supposed to tell which part of the picture is missing. The subject gets fifteen seconds to examine each picture. The test is discontinued after four failures.

Scoring- One point is given for each correct response except for last five pictures where an extra bonus score is credited if at least three pictures of the last five are correct.

  • Block Design Test– The test consists of 7 coloured blocks and a booklet with pictures of the block arranged according to specific geometric designs. The subject has to arrange the blocks according to the design shown in the picture. The task requires concept formation.

Scoring- the subject is given four points plus bonus according to the table for design 1 to 7. No points are given for the incomplete design.

  • Object Assembly- This test consists of puzzles that the subject has to rearrange in meaningful design. It requires visual-motor co-ordination, plan fullness and concept formation. The test has four puzzles. They are manikin, horse, face and auto.

Scoring-

Man: For perfect performance, 4 points are rewarded or bonus. 3 points if legs are interchanged or inverted. 2 points if legs or arms are omitted.1 point if the only trunk is correct.

Horse: Perfect performance is rewarded 6 points or bonus 5 points if the only stomach is inverted 4 points if the midpiece is omitted or legs interchanged. 3 points if the midpiece is inverted and legs interchanged. 2 points if midpiece or leg is omitted.1 point is given for every two pieces joined correctly.

Face: Perfect performance is awarded 6 points or bonus. 5 points if eyes are inverted or hairpieces omitted. 4 points if mouth and chin omitted. 3 points if large half (2 pieces) are omitted. 1 point if large half and hair are omitted. ½ point is given for each proper joint separate or joined to the whole.

Auto: Perfect performance is given 6 points or a bonus.  5 points if the door is inverted or reversed. 4 points for omitting pieces 4 & 5 or omitting piece 7. 3 points for omitting 7 and inverting or reversing piece 4, also omitting pieces 4, 5, & 7. 1 point is given for each proper joint.

  • Coding– The test consists of certain symbols that are paired with numbers or shapes. The subject has to learn them and pair with the appropriate corresponding numbers. Concentration and speed of work are important factors in this test. The test has two parts, Coding A & Coding B.

Coding A: this part is for subjects under 8 years or suspected mental defects. The test should be completed in 120 seconds. The score is the number of designs completed in that time. (Excluding samples) If the subject completes the test before time bonus point is given.

Coding B: this part is for subjects above 8 years. This section has to be completed in 120 seconds. 1 point is given for each correct response.

  • Mazes– The test requires the subject to trace through the maze and reach the end point. The test has 5 mazes which have to be completed in the given time limit.

Scoring- maze A, B, C are given 2 points if solved without error. 1 point if completed with 2 errors. Mazes 1-5 are given 3 point without error, 2 points if one error is committed, 1 point if two errors committed and 0 points when the subject passes the maximum allowed error.

Psychometric properties of  Malin’s Intelligence Scale for Indian Children (MISIC)

Reliability- MISIC was established with the test-retest method and yielded a Pearson’s Product Moment correlation coefficient of 0.91 for full-scale IQ result.

Validity- MISIC established concurrent as well as congruent validity. The former was established from school ranking whereas later was obtained from an adapted version of California short-form test of Mental Maturity for the upper age level and from the good enough Draw a Man test for the lower age level. Both yielded a coefficient of 0.63

Norms-  Indian norms are based on percentile points which were converted into IQs by Thomson formula. Using this formula anchor IQs were obtained on the basis of the standard deviation of 15 IQ.

When the IQs were plotted it gave a platykurtic graph skewed to the right. To make the graph normal two modifications were made; hypothetical 5% was added to the lower second and third standard deviation and some other modifications were made at the other extreme too. Most of the raw score fell under 16th percentile to 84th percentile; this made the 95th percentile a very high scoring norm. The abnormality of the graph was found to be due to 2 reasons; lack of subnormal cases and lack of extra normal cases.

Scoring of Malin’s Intelligence Scale for Indian Children (MISIC)

For scoring the test, the raw score of all the subtests are totalled and converted into the Test Quotients (TQs) by means of the ‘T table’ in the manual. After converting into TQs, the average of each group has to be added and found out separately. To obtain full-scale IQ both the Verbal & Performance test totals are added and then divided for the average If an only verbal group of TQs are obtained they can be balanced by adding 6% of the TQs.

Point Scale

MISIC uses the concept of point scale. All the items of a given type are grouped together in the increasing order of difficulty. The point or raw score of each subtest are totalled and converted into TQs, which are actually IQs. The subtests TQs are then added and group averaged and full scale is similarly obtained.

Standardization sample

Sample Size- for standardization purpose over 1200 children were given full individual tests during the past 6 years and over 3000 were sampled in subtest trial runs. Average of about 90 samples were used for each level including boys and girls in a ratio of 20:30. Age norms are based on a 12-month interval.

Regional Norms- For the English version, samples were taken from Nagpur, Mumbai, Shimla, Mangalore & New Delhi. For Marathi and Hindi versions, samples were taken from Nagpur alone.

Application of MISIC:

  • Used as a tool in the educational setting as well as clinical setting.
  • Helps teachers and parents in guiding students for educational and vocational planning.
  • Used to diagnose learning disabilities in students.
  • To identify children with ADHD problem
  • Used to identify talented and gifted students, and also mentally challenged students.
  • Used in identifying students cognitive strengths and weaknesses.
  • Used in tracking intellectual development.

INTERPRETATION AND DISCUSSION :

The verbal scales reflect the child’s ability to work with abstract symbols, the amount and degree of benefit she has received from her educational background, verbal memory abilities and verbal fluency.

The verbal I.Q was found to be 118 indicating above average level of verbal intelligence. On the verbal subtests, the raw scores and the corresponding IQ were as follows:

Information Test (16, 83) indicates a dull normal level of intellectual functioning in verbal ability, intellectual curiosity and long-term memory. General Comprehension Test (28, 160) indicating a very superior level of intellectual functioning in social judgment, reality awareness and understanding. She can grasp the social rules and regulations very well and has knowledge about moral codes. Arithmetic Test (18, 115) indicating an above average level of intellectual functioning in numerical reasoning and speed of numerical manipulation.

Similarities and Analogies Test (18, 115) indicating an above average level of intellectual functioning in abstract intelligence and verbal reasoning and in categorizing meaningful relationships. Vocabulary Test (40, 95) indicates an above average intellectual functioning in language usage, word knowledge and verbal fluency. Digit Span Test (13,115) indicating above average intellectual functioning, in remembering numbers forward and backward.
