Q & A

What are the Whistler scales and how do they differ from the Stanford Benet?

The Whistler scales are a set of intelligence tests created by Wisher, which include separate tests for different age groups: children, adults, and preschool/primary. Unlike the Stanford Benet, which didn't account for age beyond the formula, the Whistler scales were designed to be more age-appropriate.

What was the main issue with the original Stanford Benet that led to the creation of the Whistler scales?

The main issue with the original Stanford Benet was that it did not adequately take into account the age of the test-takers, using only chronological age in its formula, which led to the creation of the Whistler scales with separate tests for different age groups.

Which test is the Kaufman Assessment Battery for Children (KABC) and what does it aim to address?

The KABC is a well-known IQ test for children that uses tasks common to all people regardless of their cultural background. It was created to address the issue of cultural bias in intelligence testing, ensuring that the test is fair and not influenced by a test-taker's cultural background or other confounding variables.

What is the Ravens Progressive Matrices test and how does it attempt to overcome cultural bias in intelligence testing?

The Ravens Progressive Matrices is an intelligence test developed by John Raven, based entirely on pictures. This approach attempts to overcome cultural bias by eliminating language barriers and focusing on visual patterns that are universal, making it more accessible to people with different linguistic backgrounds.

What is the Wonderlic test and how is it used by employers?

The Wonderlic test is an intelligence test used by employers to screen potential employees. It has been linked to job categories, suggesting that certain IQ scores are better suited for specific types of jobs. The test is also used by the National Football League as part of their draft process.

What is the controversy surrounding the use of the Wonderlic test in job categorization?

The controversy lies in the potential for pigeonholing individuals into job categories based on their intelligence scores, which some argue is an oversimplification and may not accurately reflect a person's capabilities or potential in various job roles.

How does the script suggest the evolution of intelligence testing over time?

The script suggests that intelligence testing has evolved over time by addressing issues with previous tests, such as cultural bias and age-appropriateness, leading to the development of new tests like the Whistler scales, KABC, and Ravens Progressive Matrices.

Transcripts

so when we talk about intelligence

testing um we can talk about some of the

tests that are out there other than the

Stanford Benet because they certainly

have developed over the years um one of

the most popular ones and one that

you'll probably see as a teacher when

you're reviewing um um student files and

things of that nature um is the Whistler

scales and this um this basically uh

what Wisher noticed about the Stanford

Benet is that the um the test really

didn't take account into account age

other than the formula taking in

chronological age and so they used the

um so he created Wisher created um three

different tests for three different age

groups so he has The Wisher intelligence

scale for children which is the one

you're probably most most likely to come

across the Whistler adult intelligence

scale which you might come across too as

well if you're in the higher grades

because students with exceptionalities

can go to school until 21 in Ontario um

so that's something you might see uh and

less likely

um to see is the prary uh preschool

primary scale of intelligence um so

these are um our measures of

intelligence that Wisher has provided us

with um oh by the way there's going to

be a handful of uh bad jokes in the

pictures so feel free to pause and check

them out they're um usually I'm the only

one laughing when when they're in class

but thanks to the distance education um

you know we'll save I'll save you that

that

trouble um so we'll talk about a few

other tests that have been created uh

along the way again each of these tests

were created in response to um some

problem that the researchers noticed

about the original Stanford banet so the

Kaufman assessment battery for children

the KABC is a well-known IQ test for

children and it uses tasks that are well

known to all people regardless of

background um so for this one um the

KABC it really um helps to address the

issue of um does your culture

background or whatever um or different

um other factors other confounding

variables affect the test they're trying

to um select for things that are common

to The Human Experience rather than a

particular group which was uh something

that was wrong with the original U

test so there are um many other attempts

or tests to measure intelligence we're

going to talk about a few more here uh

but one fundamental question you can ask

yourself before we get into that is can

we quantify can we turn uh turn

intelligence into a number can we

quantify intelligence um so a simple

number for something so complex this is

a really important thing to ponder

because intelligence is a complicated

phenomenon and um you know it might be

irresponsible to think that we can put a

number on it I don't know it's been

studied for over a century though and um

I think that our our measures of

intelligence are getting better rather

than worse

so another one is called Ravens

Progressive matrices um so again in

response to the cultural bias tests uh

John Raven developed an intelligence

test based completely on pictures and so

for example this so what happened is

people that um had English as a second

language would often score poorer on the

tests and people who are native speaker

speaking uh English assuming the test

was being offered in English as an

example um but this would take away that

that bias here um so you would follow

the pattern right so you look at this

one this one and this one uh this circle

picture circle picture circle picture

and then look at the diamond and then

you'd guess okay what is going to be in

this in you would draw what would be in

this um U Box here so it's basically

completing the pattern right so in this

case it would be a diamond with four

with um with four boxes and the one on

the right hand side would be filled in

because as you can see the Shaded box is

moving

clockwise this one maybe a little bit

more complicated but I don't think

terribly more complicated um to fill in

the blanks and so on so forth so you can

check any of these out online as well if

you're interested in the different ways

in which researchers U are measuring

intelligence uh one of the most popular

tests for employers uh is called the

wonderlick test and it's an intelligence

test um developed for companies to

screen potential employees um they've

actually linked IQ to job categories

which I think is kind of bold um they're

basically saying if you have if you

score between these ranges then here are

the jobs that you'd be better suited for

which I think is quite a

um again a bold uh thing to put out on

their website I'll show you what that

looks like in a minute um here one

moment I think I have it open yeah here

it is okay so we'll take a look at the

JB job categories um as well so this um

my screen's a little small here but uh

here's okay so here's some examples

so their wonderl test is out of 40 and

so um wonderl score by job title um

systems analysist chemists are at the

high end of things on the lower end of

things uh janitorial work um uh and

things like that um security guard etc

etc um I think this is a little bit bold

I don't like to pigeon hole people um

into categories based on um their

intelligence so um I mean I'll let you

draw your own conclusions regarding

that um this was a test that was

actually adopted by the National

Football League and so um they actually

take this test and it's part of their

draft
