Summary
A decrement of avoidance response was observed in guinea pigs during a 100 or 300-trial shuttle-bos avoidance session. Amphetamine was very effective in preventing and in counteracting the performance decrement. The results are discussed in relation to the peculiarities of the level of vigilance of this species.
