Greetings,

I've been working on narrowing down the time of Woodworth's adoption of the S-O-R formula and was wondering if any of you have a copy of the 1929 (second edition) of his *Psychology* on your shelves.

What I know already about the timing of the switch is already posted at:

I'm curious whether the 1929 text shows the initial W-S-O-R-W (i.e., straight line) formula or whether he is still in the 'expanded S-R' (central tendencies) mode. He most certainly was still in the S-R mode in the 1926 Dynamic psychology article (Murchison) and apparently in the 1930 Dynamic Psychology article too --but it is not explicitly stated there. Nor is it mention in his autobiographical statement (1930ish).

As the account stands to date I've 'fudged the issue' of timing a bit and am somewhat uncomfortable about doing so.

Cheers, Paul F. Ballantyne

By 1934 he provided both a 'circular' and a 'rolling-hill' S-O- R diagram --in an effort to indicate both continuous environmental reciprocity, and learning/development respectively and both of these appear in the file listed above.

This question on 'the timing of Woodworth's S-O-R' was answered on the Cheiron listserv by Roger Thomas and Donald Dewsbury. Thanks!

The S-O-R diagram DID appeared in the 1929 edition of Woodworth's *Psychology* and the required changes to my account thereof have now been included in the following posted page:

Perhaps it can now be placed under the "Functionalism" section of this Q&A Forum but that, of course, is a debatable point.
