Term
What did Binet-Simon believe an average 3-year old could perform? And what tasks where they asked to perform in order to test ofr high achievers?
Definition
Average 3-year old able successfully to do 50% of following – point to eyes, nose, mouth, repeat two digits, enumerate objects in a picture, give family name, repeat six syllable sentence.

- Will set forward a range of tasks, starting with very easy tasks which all children would be able to answer, going through to those in the middle that only around 50% of the children will get right, then going to the higher level of which only a few will achieve.
- All children will have a sense of achievement, but only few will compete the high end sessions
Term
What did Binet-Simon believe a child of 15 and over could perform? And what tasks where they asked to perform in order to test ofr high achievers?
Definition
By 15, average child achieved 50% of following – repeat seven digits, find three rhymes for a given word within a minute, repeat a sentence of 26 syllables, interpret pictures and given facts.
- Facts they were asked about were specific to the time and the culture in which the test was developed

- By knowing what the average child of any age would be expected to achieve, it was possible to discuss extent to which any given child was performing above or below expectation.
Term
Explain the intelligence quotient
Definition
Reflecting relationship between the actual age of the child, and the age at which the average child would be expected to perform at that level, thus:

[image]

- AVERAGE WILL ALWAYS BE 100 AT EVERY AGE
- Relates only to how they perform with basic sub tasks (e.g. problem solving ability, comprehension), not their emotional responses, maturity etc.
- Cannot use this equation for adults as it does not work, cannot stop the aging process!
Term
Explain the distribution of IQ
Definition
- Measuring large samples of children IQs reveals that this characteristic is normally distributed.
- Variation in IQ scores depends to some extent on the test used (though all show this shape). Using one of the most common tests, 95% of individuals would score between 70&130
- Cannot measure a skewed population (small sample) and generalize results to the general population. Hast to be random people from a population.
- In IQ, artificially change the norm to keep it at 100, and the standard deviation is always 15%
Term
How is IQ in adults worked out? And why is the equation not used?
Definition
- We can’t stop the aging process
- A person’s performance on such tests doesn’t change much from young adulthood, and later in life it may deteriorate.
- It doesn’t make sense to say that a 45-year old performing at the level of the average 90-year old has an IQ of 200!
- Can work it out instead through stats
