“…Experiments demonstrating self-punitive responding have most often involved the use of a straight-runway apparatus with shock occurring in some intermediate portion of the alley during punishment trials (Brown, 1969). Studies in which shock has been applied in the goal box (Babb, 1963b;Eison & Sawrey, 1967;Kintz & Bruning, 1967;Seligman & Campbell, 1965) have failed to demonstrate self-punitive responding, and several theorists (Brown, 1969;Church, 1963;Eison & Sawrey, 1967;Martin & Melvin, 1966;Melvin, Athey, & Heasley, 1965) have emphasized the importance of the location of punishment in the response sequence with regard to f acilitative or suppress!ve consequences. Certainly, the weight of evidence at the present time suggests that punishment applied in the goal box is not likely to maintain responding.…”
