AB  - The presentation of tones with alternating interstimulus intervals (ISIs) of 10 
      and 70 s leads to an electrodermal response pattern with an increase in magnitude 
      after long and a decrease after short ISIs. The present study investigated 
      whether there is a relation between the occurrence of the response pattern and 
      the perception of stimuli as a pattern and, furthermore, whether the greater 
      response to the stimulus after the long ISI is due to the greater information 
      content of this stimulus (announcing the occurrence of the pair of tones). Four 
      groups, each consisting of 12 subjects, were subjected to a 1 s, 1000 Hz tone of 
      90 dB(A) intensity over 21 trials. Group I received the tones in randomized 
      sequences of 10 and 70 s, groups II and III received alternating ISIs of 10 and 
      70 s. While in group II the regularity of the stimulus pattern was interrupted by 
      the presentation of an extra stimulus, group III was confronted with a stimulus 
      omission. As a control condition, group IV received regularly alternating tones 
      with ISIs of 10 and 70 s. Skin conductance and heart rate were recorded as 
      dependent physiological variables. The perception of the stimulus patterns was 
      measured by means of a questionnaire. The electrodermal response pattern found in 
      earlier studies was replicated, and this pattern even occurred in the random 
      group when 10 and 70 s ISIs appeared directly after each other. The presentation 
      of the extra stimulus and the stimulus omission did not have any effect. For 
      heart rate, a deceleration to tones after long ISIs and an acceleration to tones 
      after short ISIs was found. Subjective pattern perception and electrodermal 
      response patterns did not coincide. In general, the results can be interpreted as 
      showing that the relationship between the ISIs seems to be of importance for the 
      occurrence of the response pattern.
