Sat, 31 Mar 2012 09:34:31 +0000 http://cognitivefun.net/talk/post/36975#r_37971 Cross multiplication is the way to go. Tue, 06 Mar 2012 05:29:06 +0000 http://cognitivefun.net/talk/post/36975#r_37080 No worries. Mon, 05 Mar 2012 12:08:36 +0000 http://cognitivefun.net/talk/post/36975#r_37004 Thanks, not sure if I'm going to take it though Sun, 04 Mar 2012 11:24:37 +0000 http://cognitivefun.net/talk/post/36975#r_37002 My score on the JCTI was about 140 too the first time I took it. Sun, 04 Mar 2012 11:09:37 +0000 http://cognitivefun.net/talk/post/36975#r_37001 You might want to try the Cambridge University Psychometric IQ test (a real IQ test) which you can take through Facebook. Sun, 04 Mar 2012 11:09:02 +0000 http://cognitivefun.net/talk/post/36975#r_37000 1)13 back 2)D10B 3)9 4)D10B 7 months (D9B 3 months), I started single after maxing out my dnb, triple, quad levels. 13 back in single was reached either the first or second day. PASAT 8 was reached in a month and posting passing scores at PASAT 8 wasn't possible without adding aerobic exercise to my training program. 5)On the Woodcock Johnson III test of achievement I scored above grade level 18 on every subtest (3 verbal, 3 math tests). No percentiles were given, the report just said above average for every subtest (I guess that means my IQ is somewhere north of 115). The test was really easy and probably doesn't have a high ceiling for someone my age (28 yrs). After months of playing single n back and engaging in other brain boosting activities my score on the JCTI (best test of fluid intelligence on the net) went up from 144 to a max of 157 (There may be a significant test-retest effect in there not sure). My full scale IQ in my opinion is probably around 130 (My general knowledge is low). Sun, 04 Mar 2012 10:57:56 +0000 http://cognitivefun.net/talk/post/36975#r_36999 Now if I was taking a professional IQ test I would use shortcuts! :) Sun, 04 Mar 2012 09:46:39 +0000 http://cognitivefun.net/talk/post/36975#r_36998 I try to do the math in my head like I am writing on a chalkboard (in much the same way that Moeman describes). I avoid shortcuts like the ones above intentionally. Sun, 04 Mar 2012 09:45:56 +0000 http://cognitivefun.net/talk/post/36975#r_36997 Moeman, if you don't mind me asking (feel free to ignore my question if you want): 1) How far did you get on single-n-back? 2) Dual-n-back 3) PASAT 4) How long did it take you to get as far as you did? 5) What is your PROFESSIONALLY administered IQ (or comparable standardized test) score? Sun, 04 Mar 2012 09:41:57 +0000 http://cognitivefun.net/talk/post/36975#r_36996 Nice system you got there. My way is simply the way one would perform the calculation on a sheet of paper. Sun, 04 Mar 2012 09:06:36 +0000 http://cognitivefun.net/talk/post/36975#r_36994 396x274 is quite easy: 4x275 = 2x550 = 1100 4x274 = 1100 - 4 = 1096 396x274 = 109600 - 1096 = 108504 But multiplying those six digit numbers ... that sounds impressive :-) Sun, 04 Mar 2012 08:42:48 +0000 http://cognitivefun.net/talk/post/36975#r_36992 I actually did one of Paul's mental arithmetic tests a few years ago and got a perfect score (nothing to brag about as the problems aren't too difficult) but didn't time it. With mental arithmetic I try to avoid shortcuts in order to maximize the load on working memory/fluid intelligence etc. The only benefits that I've noticed from mental arithmetic were temporary increases in reading speed which is why I don't do much arithmetic anymore. Sun, 04 Mar 2012 08:40:58 +0000 http://cognitivefun.net/talk/post/36975#r_36991 Momeman, if you want to, try this test and see how many you get right (including how long it takes). I try to do it without extreme shortcuts (althouth basic shortcuts I use): http://www.iq-tests-for-the-high-range.com/mental_arithmetic/ Sun, 04 Mar 2012 08:18:29 +0000 http://cognitivefun.net/talk/post/36975#r_36990 I'm glad everything has worked out for you :) Sun, 04 Mar 2012 08:14:32 +0000 http://cognitivefun.net/talk/post/36975#r_36989 Multiplying that particular sum in a minute is pretty darn impressive. It would take me about 5-10 min to multiply that sum. The most I've done is two six digit numbers ie 678,489 x 837,373 on a few occasions but don't do it often because it takes a very long time to do. Sun, 04 Mar 2012 08:12:34 +0000 http://cognitivefun.net/talk/post/36975#r_36988 ONE MORE THING: I took the GRE BEFORE I ever learned about dual-n-back. However, I have been practicing working memory tasks off on on for several years. Sun, 04 Mar 2012 07:52:48 +0000 http://cognitivefun.net/talk/post/36975#r_36987 One more thing: I DO NOT CREDIT dual-n-back for all my gains. No way. A big part of my improvement has to do with dealing with OCD/ADD and maturing as a person. Moreover, I'm not really a neurotypical. The only think I know for sure about dual-n-back is that I improved from 3 dual-n-back to 9 dual-n-back in a few months. After that, conquering other working memory tasks on this site is much easier (including PASAT). I still CANNOT do really difficult things like multiply 396 x 274 in my head within a few seconds. It would take me a minute or so to do. Sun, 04 Mar 2012 07:50:09 +0000 http://cognitivefun.net/talk/post/36975#r_36986 I got to 9 single-n-back within one or two days after having reached 9 dual-n-back. I stopped playing single-n-back on this site because I found it too easy. I can go try it again to see how long it takes me to get to 9 single-back if you want to use me as a case study :) I have an MBA. (I took the GRE instead of the GMAT) and it was accepted. I now work as the Director of International Sales for a well-known consumer electronics company. It is a pretty complex job. I was always highly creative as a young child, but I could never pay attention to anything. I was also a very slow test taker. My processing speed still isn't the greatest due to my attention span, but I got 800 on the quantitive portion of the GRE and 740 on the verbal. According to some conversion charts this would put my IQ over 160 (deviation 15) which is far too high in my case! Nonetheless, compare this high GRE score to the 370 I got in highshool on the SAT verbal and 600 on quant for a total around 970. When I took the SAT it was basically identical to the GRE except that the GRE verbal is harder. Some people think the SAT quant is harder than the GRE quant. Remember, I took the SAT cold and wasn't sure what the heck I was trying to accomplish in life at the time. My OCD was bad and so was my ADD. I scored horribly on the ACT because I couldn't pay attention to anything I was reading. Ha. I took the Ravens progressive matrices test as a kid and didn't do all that well on it either. Raven type tests are easy for me now. In general, people consider me quite smart as man in my 30s (although I still get criticized for being in my own world and not listening sometimes). I've been taking medication for OCD now (for over a decade) which has made my life far better. I'm married, have a good job, and no longer feel like an idiot. Pacman Sun, 04 Mar 2012 07:44:41 +0000 http://cognitivefun.net/talk/post/36975#r_36985 Nice score on the GRE, what's your major? Whats your single n back level? For some reason single position n back is the only n-back variant that actually works for me. Sun, 04 Mar 2012 07:18:57 +0000 http://cognitivefun.net/talk/post/36975#r_36983
