Show HN: Memory Chimp – How good is your working memory?

<p><pre><code> Uncaught SecurityError: Failed to read the &#x27;localStorage&#x27; property from &#x27;Window&#x27;: Access is denied for this document. </code></pre> I feel like this happens on the majority of the demos on the HN frontpage too. I just tried searching for what percentage of users disable cookies, and it seems like ~10% is a common figure. (Though I got numbers as low a ~1%, and a lot of confusion about third-party cookies.) I know this isn&#x27;t technically a cookie, but I think most of the major browser vendors lump it under the same preference.<p>Anyways, hackers and demo writers: degrade gracefully. On first brush with your random website, I might not want to let you track me. (I don&#x27;t know what you&#x27;re using this for.) Show me value. Or at least tell me why you need this.

Remembering a pattern seems easier than remembering the actual order. Maybe it&#x27;s because of years of using pattern unlock on my phone.<p>Very cool. Is there any theoretical basis to it? Some research? Does the ability to solve this test correlate with other qualities?

I could use some help over at <a href="https://github.com/awendt/memory-chimp" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;awendt&#x2F;memory-chimp</a><p>I&#x27;d like to use a fixed-width layout like 2048 has but cannot get it to work. The code is in a feature branch, <a href="https://github.com/awendt/memory-chimp/tree/fixed-width" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;awendt&#x2F;memory-chimp&#x2F;tree&#x2F;fixed-width</a>. I&#x27;m having trouble that the viewport is scrolling horizontally and I don&#x27;t know why.<p>I was hoping to get rid of the zooming bug using a fixed-width layout together with the meta tag &quot;viewport&quot;. That new layout could also be a chance to suggest users to try it on touch devices.

Are there any proven methods for improving working memory?<p>I forget so much of what I hear day to day, and think I could be far more effective in most regards if I could remember (something from the news, what a certain client said about X, or name of the cool company I read about etc.).<p>I&#x27;ve read several books about memory techniques, and can use the techniques actively to remember a number or a list. That is cool, however I really want to improve my working memory without needing to actively try to remember everything.

I did this the first time no problem. I didn&#x27;t memorize the order itself, but instead memorized sequential pairs (1-2, 3-4, etc...). I think memorizing each one individually would have been more difficult.<p>Working memory is a fascinating concept. I&#x27;ve played with techniques like the Memory palace and found them to be wildly effective. Attaching a meaning to any piece of information seems to make it much easier to remember.

1910 on the first try. 2614 on the second. Can&#x27;t get past 2741.<p>Here is a trick. It is very easy to rememeber up to 6 spots, but over that becomes hard. Split the numbers into groups and remember the patterns for each one and where the transition to the next group happens.

Got some high scores initially from drawing the pattern with my mouse and letting the pattern &quot;burn in&quot; to my brain.

Hangs on iPad+Chrome after a few levels (the background&#x2F;banana shows up but no numbers), but otherwise a fun game.

Very cool. But one thing: please prevent zooming. Sometimes after tapping a circle I accidently tap it twice, the site zooms in and I instantly miss the next one :)

It just says &quot;Congratulations, you won!&quot; after 9 numbers; why not more levels?<p>Also, is the time needed to remember the numbers measured or not?

Nice game. I finished the game. Had some trouble with the last level. What I memorized was what my hand movements (mouse) needed to do.

I memorised by memorising the movement my hands need to do. Nice game!

Nice game, André! Would you mind if I to port this to Android?

i&#x27;d like to regularly &amp; longitudinally evaluate my own cognitive performance.<p>can anyone recommend an app which does this?

seems like a clone of the lumosity game, which features a chip in space playing for poker chips using memory recall

Good Game.!<p>Waiting for more levels..
