Distribution of IQ score in a population:
IQ scores are distributed in such a way that the IQ scores of most people tend to fall in the middle range of the distribution. Most people show moderate level of performance i.e. in the middle range of the distribution.
Very few are on extremes showing:-
Extreme high (excellent) performance. (2.2%)
Extremely low (very poor) performance. (2.2%)
Frequency distribution for IQ Scores - tends to approximate a bell-shaped curve. It is calledNormal Curve Where the curve does not touch the x-axis.
There is no one with 0 IQ.
(may be supported by drawing normal curve showing distribution of IQ in the population).
Differentiate between psychometric and information-processing approaches to intelligence.
Answer
The psychometric approach focuses on the structure of intelligence or its underlying dimension. Information processing approach emphasises cognitive function underlaying intelligent behaviour.
The psychometric deals with ‘what’ of intelligence and information processing on ‘how’ of intelligence.
Refers to the ability to process emotional information accurately and efficiently.
It is a set of skills that underlie accurate appraisal, expression and regulation of emotions. It is the feeling side of intelligence. Some people feel difficulty in their life due to non-acceptance of emotions of others.
The ability to monitor one's own and other's emotions, to discriminate among them, and to use the information to guide one's thinking and actions (Salovey & Mayer).
Explain information-processing approach to understand intelligence.
Answer
Information Processing Approach:
It describes the processes people use in intellectual reasoning and problem-solving.
It mainly focuses on how an intelligent person acts and cognitive functioning underlying intelligent behaviour. Intelligence is not a single entity.
What is information-processing approach to intelligence?
Answer
Information processing approach:
Describes the processes people use in intellectual reasoning and problem-solving. The major focus of this approach is on how an intelligent person acts.
Emphasises studying cognitive functions underlying intelligent behaviour.
What is simultaneous and successive processing in intellectual functioning?
Answer
Simultaneous Processing: It takes place, when we perceive the connection between concepts and integrate them into a meaningful pattern for understanding. Simultaneous processing helps in grasping the meaning and relationship between the given abstract figures.
Successive Processing: It takes place, when we remember all the information serially so that recall of one leads to the recall of another. This includes learning of digits and alphabets.
