Abstract : The experiment tested the possibility that the failure of Solomon's dogs to extinguish a conditioned avoidance response was due to his extinction procedures and not necessarily to the 'just subtetanizing' shock used as the US, as Solomon hypothesized. Solomon gave only 10 trials per day and during extinction permitted the CS to remain on up to 12 times as long as the CS-US interval. The present experiment suggests that these procedures may have accounted for the resistance to extinction found by Solomon. The results indicate that resistance to extinction is a function of the CS duration in extinction. (Author)
