AB  - Data from vigilance experiments have structure. Its bases include 1/12 and 
      multiples thereof, single-digit fractions, and 1/e. Continuing previous research, 
      a table of e-based ratios (e-BR) was developed. Data from 9 published experiments 
      with regular and irregular signals (RS-IS) and from 9 with extraverted and 
      introverted subjects (E-I) were re-analyzed. Significant numerical correlations 
      were obtained, some concerning effects originally reported as nonsignificant. 
      Detection (D) means all categories ("levels" of both factors) were linearly 
      related, with p(D) approximately mean(5/8 + y/9) and p < .01. Cross-factor 
      averaged mean products of ratio D for each time period also showed convergence (p 
      < .01). The over-all mean and stability ratio of detections (SR[D], i.e., D for 
      final time period/D for initial time period, gave the scaling effect 8 square 
      root of 1/24:24 square root of 1/24. Response-time means and standard deviations 
      for different groups in Mackie, Wylie, and Smith's 1994 sonar experiments were 
      related by the derivatives of [1 - 1/e] included in the new table (p = .002). 
      Although by no means specific to vigilance (or psychophysics), the numeric factor 
      still seems relevant to research.
