Toward a New Paradigm in Deception Detection: A Psychological Perspective
https://doi.org/10.31749/2380-0550-EP2026-1-03
Abstract
This paper critically evaluates the theoretical foundations of contemporary polygraphy, arguing
that current frameworks such as Psychological Set, Relevant Issue Gravity, and Preliminary Process
Theory function primarily as descriptive labels rather than predictive scientific theories. The
author contends that these models suffer from a lack of mechanistic depth, an over-reliance on
the narrow construct of anxiety, and an outdated dichotomy between cognitive and emotional
processes. To address these limitations, the paper proposes a transition toward a new paradigm
grounded in modern affective science, specifically Scherer’s Component Process Model (CPM).
The CPM reframes polygraph reactivity as the distal outcome of a structured sequence of Stimulus
Evaluation Checks—including relevance, implications, coping potential, and normative
significance—that drive synchronization across organismic subsystems. By applying this framework
to various testing formats, the paper demonstrates how physiological responses in the
Comparison Question Test, Directed Lie Comparison, and Concealed Information Test can
be understood as distinct appraisal pathways rather than direct indicators of deception. Finally,
a three-phase research agenda is proposed to validate the role of subsystem synchronization and
sequential appraisal in deception detection. This shift from detecting lies to mapping appraisals
offers a scientifically grounded path to enhance the legal and professional credibility of the field.
