I took this test when it came out, which set me on my short affiliation with a few IQ societies. That is a story I am no longer much interested in telling.
What does fascinate me is looking at it again decades later. I remembered many of the Vocab questions and know that I have run across many of the words over time, reinforcing them. I would have to check my work with a dictionary, and then double back and try other resources if I found myself wrong, but I think I could get them all at this point. Yet I did not get them all in 1985. I did about equally well on 1-24 and 25-48 then. I don't even know which ones I got right then, though I am mostly certain on some.
For the Spatial and Numerical questions, I did not recognise a single one, except #36, which is notorious in the societies and I got wrong, and maybe #44?, which had a Eureka moment I remembered. I had an idea what I might do with most of them, but nothing came to memory, even when I started down a solving path just for fun. There were a couple of exceptions, where I intuited a guess on method that probably came from memory somehow rather than fresh thinking.
I'm big on innate versus learned on so many things at this point. Yet i do believe in reinforcement and even more especially, reward systems. Did I remember the vocabulary ones and even likely improve because I have continued to live in the world of words, while losing all the spatial and numerical memory because I so seldom visit those cities now? Or did I remember them so divergently because of brain structures in place long before I took the test? Or are the types of memory needed for these tasks fundamentally different fright out of the gate? Or am I just lazier about types of thinking I have not used in 50 years?
