Are we really teaching behaviour which says “ignore potential hazards,

Well, we are saying not everything is hazardous, yet everything is a potential hazard. After all, there are lots of things in the videos, every one of them could become hazardous, we don’t want constant clicking.

So does the test also seek to identify me, perhaps as over-cautious/sensitive?

If it does then it failed, because I passed it first time

It’s built on a probabilistic model. It is difficult to speak of individual cases, but it would seem to indicate that you at least identified the real hazards when they were there. Where stoner did not, unless you were under the threshold of click happiness and he was not.

No assessment system is perfect, but the statistical approach is used to say that the balance of probability is that Stoner is not of the required standard and you were. What is not available is how much you passed or failed by.

No I mean show on a demo where the test is calculating the first potential perception of the hazard.

That is on the review function on the demo test.

Because it’s clear that the most common reason people are missing the scoring click is because they have identified a potential hazard before the computer has opened the window for that hazard perception.

Because it is not yet a hazard. There are hundreds of potential hazards in the video, only some of them are actual hazards.

I can understand it’s to minimise capturing people blindly clicking, but it’s excluding those with faster hazard perception which is perverse.

No, it’s excluding those with an over-sensitive hazard perception

I have to retake the test with the explicit intention of delaying clicking when I identify a hazard – that’s nuts.

no, you have to retake the test and learn to differentiate between seeing something and identifying it as a hazard.

Why wouldnt it be? Is it proprietary? Is there a reason why we cant see how the test assessed for meeting it’s objectives?

Nope

So if you have nothing to fear in the methodology why not publish?

Because there is nothing new about it, there is no contribution to knowledge. A well established test validation process was used. Would expect item writers for GCSE to publish the findings of the pre-test trials?

Or at least publish the timing criteria for the hazard perception. Is it timed from the first discernible visual cue? Sometime thereafter? Does the timing window begin when the hazard is at some point in the field of view?

You mean tell you the answers??? If you don’t know when a hazard is a hazard, then you are the person we want to identify

ANy reason why we cant know these things because the test intro video is a bunch of bollocks on giving any guidance on when youre supposed to start thrashing the mouse button isnt it.

Have you tried the replay function? This might help you to differentiate between specific cases of hazard and non-hazard

How can a test designer be happy with that? It has to work in application, not just in statistical theory

What? The statistics was with regard to its practical application. Not some theoretical exercise. The data for the statistical validation was from practical application.

On any google search of forum search you find the same accusations levelled at the mechanics of the test.

of course you do, people like to complain in public. The thousands upon thousands who are quite happy with the test don’t feel the need to go to a forum and shout about it.

In fact the more I think on it, the happier I am in my opinion that it is a monkey spunk of a test regardless of the sincerity of the methodology the designers insist they used.

The methodology was not designed for sincerity, it was designed according to assessment design principles. You may be happy in your opinion that the test was no good. That’s up to you, but you have too recognise that your opinion and those of people who share similar opinions are contrary to evidence. Now in the past I have read the religious threads where people are banging on about evidence and how if some existed, then they would change their minds. I can’t present you with evidence, but I have seen it. You can choose not to believe, that too is your prerogative, and no doubt more comfortable for you. I’m not really here to argue the point. Just to let you know that this test was not some ad hoc construction. You failed it, your ego defence mechanism will only allow a limited number of reasons for this. I can’t really do much about that.

Im assuming this is published somewhere then?

No, why would it be? This is the real world not some academic tossing off exercise.

Im assuming this is published somewhere then?

So much for hazard perception. Someone should invent a test for self perception.

Lovely!

I was involved in the design and validation of the hazard test. It went through a rigorous pilot process with, novices and experts. Was validated against a series of other similar tests, giving good concurrent validity, was tested in parallel forms over time, giving good reliability, was used as a predictor for driving test performance and incident records giving good predictive validity. It’s not something just knocked up by a bunch of folks who thought it looked good. Tell me, is you life littered with a number of tests and assessments on which you should have done well, but failed to do so, because the test had not been calibrated to cope with your awesomeness?

BTW I think that falsely accusing people of racism based on the way they speak is not only unjust but can also be hugely damaging and counterproductive.

You mean like using the word ‘monkeys’?

I think MIT have an open learning portal

Here is their Mech Eng one

Terms such as ****, coon, jungle bunny, golliwog, etc, are highly offensive, and are used as insults by racists precisely because they are so offensive.

But maybe this Poiish guy was using the term ‘monkey’ in a non-racist way and he wasn’t aware that it is offensive. I find it strange, but i also find it strange that you think **** isn’t offensive, even if followed by the word ‘shop’. I wasn’l looking for an answer i liked, i just wasn’t clear. I mean the answer is clearly ‘yes’. I just found it hard to believe.

Why is it ok for you to use the term **** when speaking to fellow whites, but not ok for someone else to use the term monkey when speaking to you?maybe he sees it as harmlees as you see the term ****

That’s better, what a delightful young man you can be when you make the effort. Thank you.

well, that has answered my last question, but it’s not much use until the other questions are answered. To be honest ‘from a bike shop’ is not the most useful answer, i was hoping people would realise that i knew that much at least. implicit in the question was the request for some useful information about the best place to get the stuff, both in terms of the quality of the stuff and the support of the shop. In that respect, google is not my friend. but thanks anyway mfor your patronising input. I hope to be able to do the same for you one day.

sleep with one of her “mates” / mum

Hmmm, which would be the greatest challenge for rodeo sex?

I’ve never met an English person who is not a racist.

nudging her in what you think is the right direction will probably be a waste of time ime.

I disagree nudging her would probably be alright in this situation, but don’t try to get it it sink all the way in until after it is all over. Despite his behaviour there are still clear boundaries when it comes to existing relationships

terrier bitches all over the world

this is the site to which you should have posted.

Regarding racism generally, it is entirely wrong to run away from it

Not really, after all, they tend to be very good at running and stuff like that

Jong.

It is shame, you admit to knowing only one thing and even that is wrong.

suggest ‘Oranges are not the only fruit’

ah! Quick change artist!

My missus won’t let me have one in case women from my past inbox me whatever that means!

I think you’ll find the issues is more that you might in-box them

But anyway, the song that really annoys me is that terrible Blondie one, Debbie Harry.

“Maria, you oughta see…. her”.

Terrible ! And no excuse for cramming her wrinkly body into that dreadful corset, took so long to get that on never bothered to write the song properly

Well you can shut up now, Vyvyan Hels. You can just about blummin’ well shut up! Because if you’ve got anything horrid to say about Felicity Kendal Debbie Harry, then you can just about blummin’ well say it to me first!

Saying all Poles are racists is as daft as saying all Tories are racist

Sunshine in Manchester, drinking great coffee on the balcony, wondering how it might be improved. Then get a text from my girlfriend telling me that she’s managed to get rid of her husband for a couple of hours this evening and she’s going to be waiting all lubed up!

Fabulous!

TZ18 will be just fine. Really, they don’t need the GPS stuff which comes a couple of models up. This has some nice manual functions, if they ever want to have a play beyond P&P, but is also good straight out of the box camera

Get an X1-pro and make us all cry

i have the X10. I always carry it. I only use the D5000 when i go out to ‘do’ photography. Otherwise, the X10 is great for snapping, but more importantly, it is also very good for taking nice shots at nice places, which is when i used to carry the DSLR.

Does the Fuji x10 come close enough?

You mean he has a Mondeo Ghia as well?

Damn! He must be David Cameron or Prince Charles or Prince

Thanks for the free advice.

But seeing happy children picking flowers gives pleasure to me and many others. Stopping children from doing this is selfish as it stops us from enjoying nature. This basic joy of seeing kids enjoying themselves is so obvious i’m surprised people are questioning it.

Who decided it is good practice? How was that decision made?

Fascinating! A number of you seem to think ” my dad told me so” is good enough a reason to not pick daffodils.
Your dad mght have been clueless and just making it up.
