| 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 |

| 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 |
