摘要: The distractive influence of a series tonal pips presented simultaneously with visual conditioning stimulus was assessed using the time taken to carry out simple conditioned avoidance response as measure interaction between and non-conditioned stimuli. Presentation at three different levels intensity induced lengthening time, which potentiated by 10 20μg/kg i.p. LSD-25. When alone, however, decrease in occurred after drug had been given. introduction auditory also produced slight increase number incorrect responses. Again LSD-25, both dose levels, change an failures. effect LSD-25 on for response, therefore, appears depend upon presence or absence stimuli other than used procedure.
