(For the non psychologists among you, Edward Chase Tolman was a very influential psychologfist known for his purposive behaviorism. The Hall in which Frank and I studied at Berkeley was named after bim I am trying to understand the sense in which such variables “intervene.” The diagram below offers one possibility. I am writing you today because I hope the hunters among you will straighten me out on how to go about firing a gun at a rabbit. By “find rabbit” I meant “orient toward rabbit”. I guess I know that stumbling around in the forest with a cocked shot gun looking for a rabbit is not good hunting technique. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><img width=842 height=483 style='width:8.7708in;height:5.0347in' id="Picture_x0020_2" src="cid:image001.png@01D71BE2.5C67BBE0"><o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Nick Thompson<o:p></o:p></p><p class=MsoNormal><a href="mailto:ThompNickSon2@gmail.com">ThompNickSon2@gmail.com</a><o:p></o:p></p><p class=MsoNormal><a href="https://wordpress.clarku.edu/nthompson/">https://wordpress.clarku.edu/nthompson/</a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
