<p>In a lot of places in psychology - for example in operant conditioning and in describing symptoms of psychological disorders - various things are described as "positive" and "negative".

They are used in conditioning because those terms were originally used by [Skinner](https://en.wikipedia.org/wiki/B._F._Skinner), and after some shuffling around ("negative reinforcement" used to be used to describe what is now called "punishment" or more specifically "positive punishment") became standard terms. [Dinsmoor (2004)](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1285013/pdf/15693525.pdf) covers a bit of the history and cites the relevant source literature.

For the positive and negative symptoms of schizophrenia, that goes back earlier, to Bleuler who was also the first person to use the term "schizophrenia" in 1908 to describe the disease known by that name today. The 1908 use of schizophrenia was at a conference, but there are also published books and articles by him later that use the terms, I've included a reference to one from 1912 below.
