Comprehensive Guide to the Wechsler Adult Intelligence Scale (WAIS)

Hi everyone. So we are back to my channel and we're talking about today the virtual adult intelligent scale ways

and please remember to subscribe, like and comment and share with your friends.

This video will tap into all the descriptions about Vela. Who is Vela? What is instrument all about? And we are

starting immediately that a vual adult intelligence scale tabs to check assess individuals um intellectual capacity and

functions. Yes. U persons exposed to this is from 17 to 89 years. Yes. It's not for children. We have whisk va

intelligence skill for children but that is not under the py of this video. Right? We are only talking about the

ways wa intelligence skill. So it is by David Vesler who believed that um intelligence should not be considered

only in verbal functioning and a lot of but also your performance aspect your your ability to overcome several

adversities and all of those things. So Vela looks at it that way. David Vesler an accomplished scholar his philosophy

of intelligence his understanding or his own position about intelligence is that he referred intelligence as individual's

global capacity to act purposefully think rationally and deal effect effectively with his or her environment.

individual's global capacity to act purposefully, think rationally and deal effectively with his or her environment.

As a psychology student, you understand we have the thinking, the feeling and the performance domains there. Right?

You see that there is thoughts, emotions and behavior in his definition of intelligence. Right? Now we continue. So

the development of this instrument this 1955 ways and It has gone through several revisions.

So the the one we're talking about today is a wage two right is um 1955. The initial was in 1939. The one we often

call the ble test right 1939. But ways two as we having today that we're going to be discussing is 1955. Then 1981

1981 is the revised form. Then w three came in 1997. W 4 came in 2008 and

ways 521. Yes, that is the revisions of the virtual adult intelligence scale. This

instrument like I said assesses the intellectual function of older adults from 17 to 89 years. So the composition

of the instrument is what we'll go straight to talk about. Now very quick first there are two domains.

Two there are three composite scores and four three this time there are four index scores two domains three index

scores and four composite scores and 14 sub tests. When you are good with this, you are

good with the instrument. As a student of the instrument of as a student of psychological psychology or psych

psychometric or psychological testing or whatsoever if you're exposed to this as a student know as we have revised and

next you need to know is that there are three two domains three index scores four

no three composite scores four index scores, 14 sub tests and we are going to go through them quickly. So

by the two domains we have the verbal and performance domains. These are the two domains of the MNBI

right. Then the index course we have the um FSIQ, VIQ and PIQ. VIQ that is verbal um verbal intelligent quotient P

performance intelligent quotient that is the second one and FSIQ full scale intelligent quotient. So you

understand that P IQ plus VIQ is equal to FSIQ. When you add up the verbal intelligent quotient to the performance

intelligent quotient, you have the full scale intelligent quotient. Yes. Do you understand? I hope that is cool. So the

the um yeah the index course now right the index course include the working memory

index the the verbal comprehension index the uh

processing speed index and perceptual organization index index. Yes. These are the the um

index scores. Yes. Okay. So the the uh what do we call it the 14 sub test you've discovered that seven out of

them are under under verbal domain. And the

just like the verba domain viq is another va domain piq the composite score is under performance then wm and

that is working memory index and verbal compression index is under under what is it called um the verbal

while processing speed and perial organization index are under performance domain right that is performance

question also Then the verba doain have seven sub tests while the performance has seven making them 14. And the

subtests under um verbal domain include vocabulary with 40 items. Right? It has 40 items there. The descriptions I'll

try to give you a little description. It tests uh things like comprehension, semantic knowledge. Yes. and people the

clinician often present it orally. Yes. Then we have similarity with 14 items. Abstract verbal reasonings and semantic

knowledge are tested also here. then it's also presented orally then the that similarity you check how similar

two words are those kind of thing right yeah I'm trying to give you a little brief description right then information

is the third we have talked about vocabulary we talked about similarity now we're talking about information

that's second third one right it has 29 items we talk about General knowledge about

your culture. Yes. Then comprehension is the fourth one. 14 items.

Practical judgment and common sense are tested here under comprehension. Yes. Then even socialitation are presented

also. Then the fifth one arithmetics 14 items. They want to check your quantitative

reasoning even your mental manipulation your concentration level and is presented orally that is by orally and

with timing there is serious timing there. Yes. And there's no pen and paper to do that in this situation right

arithmetics. Digit span is number six. Yes.

Digit span that is 69 items. Am I correct? Uh it's about 3 to 9, not 39. I don't know. Yeah. But around this

number, we will confirm that later. So this where we look at the encoding, auditory processing, your working memory

is what we check here in this um scale six and it's presented mostly in two parts and you must do it in ascending

order and produce it immediately. Then the Last among this barber domain is letter number sequencing. The letter

number sequencing is the last one and is 21 21 letters and we test your attention your control work memory and here things

are done in the test goes like you getting verbatim. Yes. to recall something alphabetical

order and in increasing order as a matter of fact. Now the performance domain also have seven sub

tests and we are having picture completion block design metric reasoning digit symbol coding we have symbol

search arrangement and object assembly. So the the picture completion test they have 21 cards right and then block

design 14 models of geometric patterns it's not necessary I'm trying to

give you how it is done right okay so uh we we have the metric reasoning that is the third one 26 incomplete patterns yes

how it is done. You you consider that when you make yourself available in size center you see how it's done they can

administer that to you right then okay so we have digit symbol code in number four

nine of the symbols yeah there are nine in in total I don't want to give you how the these

things are done right then we have symbol search symbol search number five then we We have uh a picture arrangement

number six seven items here. Then we have um object assembly five puzzles

that made of five puzzle that are presented standard format and meaningful hole. You should try to make meaning of

the whole puzzle have been scattered. Yes. Here we checked deductive reason. Okay. So

the question now is who can take the the first who can take it? Any person from 17 to 89 years can take it. You can be

administered or you can be assessed using the MNPI and others apart from this they must be from 17 to 89 and they

include the general population both your parents right the parents the uh

workers teachers and clinical population is another population apart from general population right that can take these

these uh excuse me, individual with special needs, mentally physically or physically

challenged, the elderly and students uh maybe maybe those students that have some intellectual disability all of

those things. And another question is who can administer? We have discussed who can take it. Now who can administer

it? Two things must be in any clinician, any expert, any person that has a a training on the use of psychological

instruments and two any person that have a training on the use of the vessel

which ways. Yes, vular adult intelligence skill. One, you must be exposed to psychometric. You must have

had a good training on instrument and you have a good training on the use or administration.

Yes. Of the instrument. Yes. So that is

that is the size. Um what again am I forgetting the time required is often 90 minutes that is 1 hour 30 minutes. So

for for a matter of fact I would have loved to discuss um a very important thing but I'll perhaps produce it in

another video chron chronological age because the vessel must be introduced or administered with an understanding of

the chronological age perhaps I may want to do it here. So we we do the chronology age in this way before you

are administered the chronological I mean the vesa adult intelligence scale to know your um your IQ level right your

intelligent question um they want to understand your mental age. So your chronological age and your mental age

they are different right. So how do how is it done? A person born in 1990 um let's say um November 25, 1990.

So um and today is um um November no December 4th nove December 4th 2025. So how do we calculate the uh mental age

of that individual? First we write today's date which is 25 no 2025. Give space you have um December December is

12 and then today is 04. So under that 2025 we write 1990. under

the December we write 11 under okay I will rather substitute um December for

okay let me see so that it will go hoping it will go well so I wanted to take the way we carry these things so 12

and then November is 11 then under 04 we are having 25 so 04 minus 25 cannot go right what we do

is that When we are borrowing from the month, we are borrowing according to the assumption by the vessel. Every month is

30 days. Every month is 30 days. So we are borrowing from that two in 12. So we are borrowing one there and that one we

are borrowing is 30 days. So 30 + 04 that is 34 minus 25 we having 9. Yes. Hopefully 09 down there. Right now here

is 111. Right? 11 up 11 down. So had it been there is a need to borrow from the other side that is in 2025 we would have

borrowed one and that one will become uh 12 because it is 12 months that make up one year

12 months. So if you have borrowed in 2025 it will now remain 2024 but that one we borrowed will become um 12

because it's 12 months going to the month now it will be 12 + 11 but we don't need to do that right so since 11

can go with 11 we have 0 0 there right and then 2025 under 1990 right so five under that is z

we have five z minus 5 - 0 is five then Another the other way we are having uh carrying

one from here we are having 12 then we have three. So the person at that point is 30 years 0 months and 9 days at the

date you are about to be administered the vular adult inclusion test. If you are confused with this please hit the

comment box. I'll be glad to hear from you and discuss with you and thank you very much and see in the other videos.
