Although many people believe it tells you whether a person is lying or not, it does not work that way. <strong><a class=\"wpil_keyword_link\" title=\"The polygraph\" href=\"https:\/\/elpoligrafo.es\/en\/\" data-wpil-keyword-link=\"linked\">The polygraph<\/a> is responsible for recording a person's physiological activity.<\/strong>. And this information is generated from the individual's own nervous system.<\/p>\n<p>Knowing this, it is a device that contains an arm with a needle at the tip (in the older models, nowadays digital). With this, the polygraph draws lines on paper according to the <strong>physiological responses <\/strong>the person is having during the interview.<\/p>\n<p>Obviously, with the result of these <strong>physiological responses<\/strong>If a person is lying or telling the truth, an expert can tell whether he or she is lying or telling the truth. The human body has <strong>responses such as fear, doubt, embarrassment, etc.<\/strong>. Even if you hide this from others, the truth is that your body and your physiological responses do not lie.<\/p>\n<p>However, manipulating and reading the results of these devices requires experience and study. Therefore, <strong>not just anyone is capable of reading and using a polygraph<\/strong>.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><div class=\"vc_row wpb_row vc_row-fluid\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><style type=\"text\/css\" data-type=\"the7_shortcodes-inline-css\">.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d figure,\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d .rollover,\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d img,\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d .gallery-rollover {\n  border-radius: 0px;\n}\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d.enable-bg-rollover .gallery-rollover {\n  background: -webkit-linear-gradient();\n  background: linear-gradient();\n}\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d.enable-bg-rollover.hover-scale figure .rollover:after {\n  background: -webkit-linear-gradient();\n  background: linear-gradient();\n}\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d .gallery-zoom-ico {\n  width: 44px;\n  height: 44px;\n  line-height: 44px;\n  border-radius: 100px;\n  margin: -22px 0 0 -22px;\n  border-width: 0px;\n  color: #ffffff;\n}\n.dt-icon-bg-on.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d .gallery-zoom-ico {\n  background: rgba(255,255,255,0.3);\n  box-shadow: none;\n}\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d .gallery-zoom-ico:before,\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d .gallery-zoom-ico span {\n  font-size: 32px;\n  line-height: 44px;\n  color: #ffffff;\n}\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d:not(.resize-by-browser-width) .dt-css-grid {\n  grid-row-gap: 10px;\n  grid-column-gap: 10px;\n  grid-template-columns: repeat(auto-fill,minmax(,1fr));\n}\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d:not(.resize-by-browser-width) .dt-css-grid .double-width {\n  grid-column: span 2;\n}\n.cssgridlegacy.no-cssgrid .gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d:not(.resize-by-browser-width) .dt-css-grid,\n.no-cssgridlegacy.no-cssgrid .gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d:not(.resize-by-browser-width) .dt-css-grid {\n  display: flex;\n  flex-flow: row wrap;\n  margin: -5px;\n}\n.cssgridlegacy.no-cssgrid .gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d:not(.resize-by-browser-width) .dt-css-grid .wf-cell,\n.no-cssgridlegacy.no-cssgrid .gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d:not(.resize-by-browser-width) .dt-css-grid .wf-cell {\n  flex: 1 0 ;\n  max-width: 100%;\n  padding: 5px;\n  box-sizing: border-box;\n}\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d.resize-by-browser-width .dt-css-grid {\n  grid-template-columns: repeat(3,1fr);\n  grid-template-rows: auto;\n  grid-column-gap: 10px;\n  grid-row-gap: 10px;\n}\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d.resize-by-browser-width .dt-css-grid .double-width {\n  grid-column: span 2;\n}\n.cssgridlegacy.no-cssgrid .gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d.resize-by-browser-width .dt-css-grid {\n  margin: -5px;\n}\n.cssgridlegacy.no-cssgrid .gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d.resize-by-browser-width .dt-css-grid .wf-cell {\n  width: 33.333333333333%;\n  padding: 5px;\n}\n.cssgridlegacy.no-cssgrid .gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d.resize-by-browser-width .dt-css-grid .wf-cell.double-width {\n  width: calc(33.333333333333%) * 2;\n}\n.gallery-shortcode.gallery-masonry-shortcode-id-67238085c952a0d8c4d463375525781d.resize-by-browser-width:not(.centered-layout-list):not(.content-bg-on) .dt-css-grid {\n  grid-row-gap: 10px -

It was from this moment that <strong>this instrument began to be used to <a href=\"https:\/\/elpoligrafo.es\/en\/can-a-polygrapher-detect-lies-by-omission\/\">detecting lies<\/a><\/strong>. Subsequently, this<strong> was improved by Leonard Keeler <\/strong>in the 1930s who perfected it by creating a much more effective and accurate device. It not only measures blood pressure, but also the blood pressure in the bloodstream. <strong>pulse rate and respiration<\/strong>.<\/p>\n<p>Years later<strong> Keeler developed the graphic paper <\/strong>to implement a new printing mechanism. This made the results of the polygraph long-lasting.<\/p>\n<p>As the years went by, more companies became interested in these devices and started to sell them commercially. Including, <strong>in 1945 John Reid developed a system for recording muscle activity.<\/strong>. This was achieved thanks to a special chair that measured the individual's movements.<\/p>\n<p>For the decade of <strong>1992,<\/strong> Stoelting launches a <strong>improved version<\/strong>which was <strong>the first digital polygraph<\/strong>. Instead of printing on paper, the results were displayed on a computer screen. From this point on, polygraphs became more compact and accurate. However, it is still possible to find some traditional needle polygraphs.
