Vigilance as a table of numbers

N Richardson

    Summary

    Vigilance experiment data reveal underlying numerical structures based on mathematical constants. These findings suggest a consistent, quantifiable pattern in human detection and response times across various experimental conditions.

    Area of Science:

    • Cognitive Psychology
    • Psychophysics
    • Mathematical Psychology

    Background:

    • Vigilance experiments yield structured data.
    • Previous research explored mathematical bases in vigilance.
    • This study continues the investigation into numerical patterns.

    Purpose of the Study:

    • To re-analyze existing vigilance data using a novel table of e-based ratios (e-BR).
    • To identify significant numerical correlations within vigilance data, including previously unreported ones.
    • To explore the relevance of a specific numeric factor in cognitive research.

    Main Methods:

    • Re-analysis of data from 18 published vigilance experiments (9 RS-IS, 9 E-I).
    • Development and application of a table of e-based ratios (e-BR).
    • Statistical analysis of detection (D) and response-time data.

    Main Results:

    • Significant linear relationships found between detection (D) and experimental factors (p < .01).
    • Cross-factor analysis showed convergence in detection ratios across time periods (p < .01).
    • Response times in sonar experiments correlated with derivatives of [1 - 1/e] (p = .002).

    Conclusions:

    • Vigilance data exhibit quantifiable numerical structures based on mathematical constants like 'e'.
    • The identified numerical patterns are relevant to understanding detection and response times.
    • The findings suggest a broader applicability of these numeric factors beyond psychophysics.
