In fact, scientists have discovered that the harder you must work to solve a problem, the wider your pupils will dilate. You have reached the normal level of easy memory for most people and the mental effort required to go beyond seven digits will easily dilate your pupils. Now have your friend ask you to remember a series of seven numbers. Go to a mirror and have a friend ask you to remember and recite back six numbers. Mathematics is a good example of a mental problem capable of dilating your pupils. This is an activity involving short term memory that gives continuity to our thoughts and allows us to, for example, multiply 9 by 12. Scientist like to compare this kind of activity with a computer's RAM memory, or active memory. We have learned that pupil dilation is an indication of a special kind of brain activity, or "hard thinking". Even more important is that we now have brain scanners PET and fMRI machines that can match the inner activity of our brains with observed variations and patterns in our pupil size. Today we have the benefit of extremely accurate pupillometers, as they are called, that are small, transparent and digitized. Experiments in the mid-60s seemed to confirm that the pupil response to naked pictures of men and women was indeed different for homosexuals and heterosexuals, and more recent studies have confirmed this, nevertheless the "fruit machine" was abandoned in the late 1960s. The Canadian machine involved a bulky camera which was barely able to measure a change of one millimeter of the pupil's diameter. Although funding for the "fruit machine" project was cut off in the late 1960s, the investigations continued, and the RCMP collected files on over 9,000 "suspected" homosexuals. A substantial number of workers did lose their jobs. The "fruit machine" was employed in Canada in the 1950s and 1960s during a campaign to eliminate all homosexuals from the civil service, the Royal Canadian Mounted Police (RCMP), and the military. It was designed to ferret out homosexuals from joining the RCMP (mounties) by flagging those whose pupils dilated to the images of males. This was a crude device by today's standards and measured the pupil size of military recruits while showing them pictures of naked men and women. The observation was first implemented by the Canadian government in the early 1950s in a device that was sarcastically referred to as the fruit machine. This matter should become relevant when you consider that technology such as SmartPhones and computer "glasses" are equipped with hi-resolution cameras and have the audio and visual display plus the computer power to effectively do this, here and now.Ĭhanges in pupil size have been known to be associated with aroused states in humans for a very long time. The suggestion need not be consciously perceived to be effective. Experiments have already proven this to be effective.īy monitoring for the "enhanced learning" neural pattern, reflected in pupil size variations, a pre-determined suggestion can be delivered by the same device at precisely the most effective moment. Private and intimate thoughts can be ascertained and cataloged by presenting specific images or sounds and recording the pupillary response. The ability to precisely monitor pupil size in real time, while silmultaneously presenting visual and/or audio stimulation, presents an opportunity to both monitor and control the belief systems of the subjects. It has now been shown that these same mental states are reflected in the variable size of the pupil which, as it turns out, varies not only from adjustments to light and darkness, but to the arousal of a certain region of the brain, the locus coeruleus - a kind of neural "hub" active in processing our "working memory" or RAM. Taking advantage of these "enhanced learning" states has therefore been impractical. Ordinarily, these brief mental states are only observable with an fMRI or less accurately with an EEG. It is a known fact that the mind is extremely receptive to new ideas during certain phases of activity associated with processing new or unexpected sensory stimulation. In this article, you will learn that the science of pupillometry - measuring the changes in the diameter of your pupils in real time - has the ability to reveal mental activity associated with everything from sexual preference, future job peformance and repressed memories to the condition of your autonomous nervous system, your overall health and what medication or drugs you have taken. That's because the same technology - called pupillometry - can not only accurately read your mind but can actually change it. If "they" succeed, you probably won't even notice, let alone care, when your most intimate and private thoughts are accessed by a new technology just coming on the scene.
