It's the specific social rule you must learn to follow. Neurotypical humans know how to ascertain social rules from their surroundings, even when they are not made explicit. That's why nearly every teenager gets the drinking age rule right, but still might not get the "he didn't put gas in the car" side of the rule right--because that's NOT a universal social contract to them.<br /><br />Few people jump contextual boundaries and see the similarities. That's because the contextual boundaries tell us to whom we're loyal, or when we feel pride, or when we can dissemble. The if-then ness of a card game just doesn't affect our species' survival the way telling the loyal group member from the sociopath does.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-13479064080506324582011-06-11T16:56:03.443-07:002011-06-11T16:56:03.443-07:00Am I a psychopath if I found the number/color vers...Am I a psychopath if I found the number/color version much easier to see the answer to immediately than the car/petrol one?GoogleMasternoreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-73127449466880365722011-06-11T15:06:33.053-07:002011-06-11T15:06:33.053-07:00Another interesting element: I think I read at Lan...Another interesting element: I think I read at Language Log that if you substituted something like "California," "Nevada," "patient," and "impatient" and gave the rule as "People who live in California are patient," the test is very difficult to do. In other words, although "Californians are patient" is a great deal less abstract than even-odd and color, the greater degree of concreteness doesn't make the problem appreciably easier.<br /><br />People do well **specifically** on 'social contract' and 'risk' questions.Catherine Johnsonhttps://www.blogger.com/profile/03347093496361370174noreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-77650246135373973412011-06-11T15:03:45.863-07:002011-06-11T15:03:45.863-07:00fyi: the article was about an ingenious study of p...fyi: the article was about an ingenious study of psychopathy. The authors reasoned that psychopaths, who do know moral rules, use 'reasoning' as opposed to 'emotion' to make moral judgments. (I'm using quotes because I don't remember how they put it, exactly.)<br /><br />If that's true, then psychopaths ought to have as much difficulty doing the borrow car/put gas in the tank problem as the abstract problem.<br /><br />Sure enough, prisoners who tested high on psychopathy had significantly more trouble than normal people handling the car/petrol question.Catherine Johnsonhttps://www.blogger.com/profile/03347093496361370174noreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-88989159055408684812011-06-11T15:00:17.849-07:002011-06-11T15:00:17.849-07:00I say it's B: being able to do the first versi...<i>I say it's B: being able to do the first version of the task correctly indicates a high ability to reason abstractly, making it easier to do math.<br /></i><br /><br />That's the answer I was fishing for!Catherine Johnsonhttps://www.blogger.com/profile/03347093496361370174noreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-80526594782939991132011-06-10T19:28:12.827-07:002011-06-10T19:28:12.827-07:00People understand what B means, and life teaches t...People understand what B means, and life teaches them that by adulthood--what conditions must I check? Few recognize the relationship between the 2nd version (car and gas) and the first. That's been shown by research over and over. <br /><br />Nearly all teens get this question right if phrased as "if you want to drink, you must have an ID that says you're 21 or over." I'm drinking beer; you're not; he's 17 and drinking something dark; she's 35 and drinking something in light. Who/what must you check to make sure everyone is behaving legally?" They know the beer drinker needs to be checked for ID, and that the 17 yr old's drink needs checking for no alcohol.<br /><br />That's because these conditions are pre programmed in their head, not because they see the truth values of if-then relationships to their inverse,converse, or contrapositive.<br /><br />Knowing more math doesn't make you more likely to get B right. It makes you more likely that you'll know how to do A, even if you STILL don't see the connection to B. (because you have explicitly learned that a - > b is equivalent to its contrapositive not b -> not a)<br /><br />The point is that even math-literate people don't get the connection between the two questions.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-2907470898994762982011-06-10T17:12:08.808-07:002011-06-10T17:12:08.808-07:00I say it's B: being able to do the first versi...I say it's B: being able to do the first version of the task correctly indicates a high ability to reason abstractly, making it easier to do math.<br /><br />Then again, maybe having done enough math increases one's ability to reason abstractly.Hainishnoreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-72803917930583766722011-06-10T16:52:46.876-07:002011-06-10T16:52:46.876-07:00http://www.textsavvyblog.net/2007/05/wason-selecti...http://www.textsavvyblog.net/2007/05/wason-selection-task-part-i.htmlAnonymoushttps://www.blogger.com/profile/16517742269292732960noreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-37777923097565455292011-06-10T15:50:39.020-07:002011-06-10T15:50:39.020-07:00“If a card shows an even number on one side, then ...<i>“If a card shows an even number on one side, then it is red on the other.” Which cards do you need to turn over to tell if the rule has been broken?<br /><br />[snip]<br /><br />In terms of formal logic, the problems are the same.
