Nos gustaría agradecer a los examinadores que participaron en este estudio;

Se han sugerido soluciones alternativas para la manga de brazo braquial tradicional utilizada en las pruebas poligráficas de evaluación de la credibilidad, con el fin de reducir la vulnerabilidad de los datos del sensor cardiográfico debido a artefactos que pueden deteriorar el aprovechamiento de los datos, y para reducir el nivel de incomodidad fí...

Alternative solutions have been suggested to the traditional brachial arm cuff used in polygraphic credibility assessment testing to reduce the vulnerability of the cardiograph sensor data to artifacts that may disrupt the usability of the data, and to reduce level of physical discomfort that may be experienced and reported by polygraph examinees....

Se discuten las Preguntas de Comparación de Mentiras Probables y de Mentiras Dirigidas dentro del marco de referencia de cómo se utilizan para generar niveles apropiados de saliencia bajo la teoría analítica del polígrafo. Los autores proporcionan un marco de referencia para el proceso de introducción de ambos tipos de preguntas de comparación y di...

Trata de plantearte esta tarea: no pensar en un oso polar, y verás que la maldita cosa vendrá a tu mente cada minuto. [Fyodor Dostoievski, Notas de Invierno sobre Impresiones de Verano, 1863] Las preguntas de comparación se utilizan en las pruebas de detección psicofisiológica del engaño (PDD) para proporcionar una base de información registrada pa...

It is likely that both PLC and DLC questions will continue to be used in polygraph field practice, long into the future. Both PLC and DLC questions require skill, training, and some experience. However, DLC questions are easier to learn and easier to standardize because they are less on dependent individual personality or examiner subjectivity as v...

Probable Lie and Directed Lie Comparison Questions are discussed within the framework of how they are used to generate appropriate levels of salience under the analytic theory of the polygraph. The authors provide a framework for the process of introducing both types of comparison questions and discuss the concept of the Ironic Process Theory as it...

Comparison questions are used in psy-chophysiological detection of deception (PDD) testing to provide a basis of recorded information to increase the objectivity, reliability, and reproducibility of analytic conclusion about deception or truth-telling in response to relevant test questions. The comparison question test (CQT) was first described in...

Describimos el uso de un proceso analítico estructurado para la actualización Multinomial del Sistema de Puntuación Empírica (ESS-M). El análisis de datos de polígrafo comienza con la extracción de características, la transformación numérica y la reducción de datos. Las etapas posteriores del análisis incluyen el cálculo de un clasificador estadíst...

We describe the use of a structured analytic process for the Multinomial update to the Empirical Scoring System (ESS-M). Polygraph data analysis begins with feature extraction, numerical transformation, and data reduction. Later stages of analysis include the calculation of a statistical classifier and the parsing of a categorical test result from...

We discuss the published literature on the effectiveness of the known-solution acquaintance test (ACQT). Although studies have not supported an effect for the unknown-solution ACQT, the known-solution ACQT is better supported by scientific evidence. Some important advantages of the known-solution ACQT is that it does not engage a role-reversal, whe...

Un estudio de crimen simulado aplicado con población Mexicana, puso a prueba la efectividad de una técnica poligráfica experimental diagnóstica de evento-específico con una sola secuencia, con dos preguntas relevantes. El protocolo experimental tuvo una precisión no ponderada de 87%, una tasa de inconclusos de 18%, una sensibilidad de 80% y una esp...

A mock crime study on a Mexican population tested the effectiveness of an experimental single-sequence event-specific diagnostic polygraph technique with two relevant questions. The experimental protocol had unweighted accuracy of 87%, an 18% inconclusive rate, sensitivity of 80%, and specificity of 93%. Reliability via Kappa's statistic was .73. S...

A previous laboratory study of a diagnostic polygraph technique in a single sequence reported results consistent with other validated techniques. This replication of our previous research included 163 new examinees and tested the effectiveness of an experimental single-sequence event-specific diagnostic polygraph technique with two relevant questio...
