Can intelligence be measured without an IQ test?

In principle, you can also query other parameters.For this I found a very nice and simple, but very valid, concentration test of the University of Saarland, which is not yet definitively standardized, but highly correlated with the number connection test (ZVT) …

Concentration test zrf_20_5

The test is suitable for testing adolescents and adults and I think it is fun and as the author of the test has determined, the result cannot be decisively influenced by training, so you don’t get better (faster) even with a lot of training.

It should be noted that the test has so far only been carried out with 100 teaching students aged 22 on average (the average is 20.9) compared to those of your results, so if you are older than 24 years, you will have to use the table below. Compare the test result with the ZRF 20 mean for mentally healthy people (no cognitive impairment) applicable to your age group.

estimated mean

Age – Time in sec

18-24 – 21

25-34 – 22

35-44 – 26

45-54 – 29

55-64 – 30

65-74 – 36

75-84 – 48

85-90 – 55

As a yardstick and explanation my result:

I have an IQ of 138 measured by the Hamburg-Wechsler-Intelligence test and reach a value of 13.6, so I would still be able to concentrate among students (whose IQ in the age of 50, without any adjustment to my age) in terms of concentration among students (whose IQ in the higher than the population average) in the top 5%.

As written above, this concentration test correlates highly with the number connection test (ZVT) for the test reliability values of r = .81 to .97.

Extensive data are available on validity and the ZVT correlates with traditional intelligence tests medium to high.

Another quick way to measure its intelligence is the Short Tests for General Intelligence Parameters (KAI) (see here from page 38)…

Take a stopwatch (e.g. on your mobile phone) and read aloud!!!

(e.g. best value from 10 tests) precedes the letter sequence and thus gets a value that according to research is pretty much correlated with IQ values from standardized IQ tests.

This would now be a very shortened version of the KAI, which consists of letter reading (BUL) and characters (numbers) afterspeak, and in which a formula is then obtained using correction tables (in the PDF above on p.55) which then gives the short memory capacity (KK) in bit outputs what then looks like:

* Letter reading

o Only the shortest read time is used.

o Working speed Ck (bit/sec)

+ 20 letters of 5 bit = 100 bits per row of letters

+ Ck = 100/BuL

* Follow-up (ZN/BN)

o ZN is corrected downwards to make it more comparable to the BN value (in ZN you are on average better than in BN)

o Present duration TR (sec)

o TR = (ZNk + BN) / 2

* Short storage capacity KK (bit)

o Short storage capacity = working speed x present time

o KK = CK x TR

* The short storage capacity KK, as well as the base capacities (CK, TR) can be assigned to IQ points.

* It is recommended to allocate the short storage capacity KK.

KK 153.19 bit = (Ck = 100/4.6sec) 21.73 x (TR = (7.1 + 7) / 2 ) 7.05 ——— corresponds to empirical observations IQ 135

….but you can also keep this short and use the fun factor of quickly reading the letter sequence and get an approximate value over the determined time, if one does not cheat yourself during the timekeeping ;).

But here, too, these are all tests that are normally carried out by trained personnel under clinical conditions, i.e. always observe this during self-testing and have the whole thing checked if necessary, or in case of doubt by experts.
