"Bread, Please" as Conditioned Response

I'd like to pursue the ideas to which I alluded here a week ago.

B.F. Skinner's book, Verbal Behavior (1957), grew out of a series of lectures he gave at Harvard in 1947-48. It naturally draws my attention that these were the William James Lectures, sponsored jointly by Harvard's Departments of Psychology and Philosophy. This is a series of lectures that began in 1930 and continued until the 1980s, and that hosted some of the most illustrious thinkers of that period within the interchange of those two disciplines. Just for example, not to elevate those above the others: Arthur Lovejoy gave the WJ lectures in 1932-33; Karl Popper in 1949-50; Gabriel Marcel in 1961-62.

The fact that Skinner gave his lectures on "verbal behavior" ten years before the publication of the book of that name would seem to suggest a considerable modification between the one format and the other.

Anyway, the book may be found here.

He defines "verbal behavior" in the first instance as "behavior shaped and maintained by mediated consequences," i.e. that has its desired effect through the actions of a listener. The desired effect of "bread please" is to persuade someone else at the table to move an object around, where physical constraints or social convention prevent the speaker from obtaining the bread for himself. Skinner later refines that definition a bit, but that remains a key to his approach.

"Bread please" seems a behavior generated by operant conditioning in a rather straightforward way. For a youngter, saying "bread" will suffice to get the bread. Indeed, one's parents (the conditioners) will likely be delighted that their child can form the word, so they will happily reinforce that speech by handing over a piece of bread. Later, though, "bread" earns only frowns unless modified by "please," so the growing child is brought within the scope of social convention.
More elaborate usages of language are only very complicated instances of the operation of much the same mechanism whence comes the phrase "bread please." That, at any rate, is Skinner's view. One of its advantages in his eyes is that it gets rid of the idea that words have meaning in the sense in which "meaning" might be something inside the brain and hidden from science. Words only "mean," for Skinner, because they get listeners to do things, and the doing is "as observable as any part of physics."

That is enough for today. I will say more soon about why Chomsky objected to the study of language in these terms, how later Skinnerians reacted to Chomsky, and how the dispute feeds into the question of the differentia of the human species.
