Subthreshold Stimulus: Exploring Invisible Influences

In the modern world, we are faced with a huge number of different stimuli that affect our psyche and affect our behavior. However, there is a category of stimuli whose magnitude is below the threshold value and therefore goes unnoticed by most people. These stimuli are known as subthreshold stimuli or P-stimuli. In this article we will look at the concept of a subthreshold stimulus and its potential effects on our state and behavior.

A subthreshold stimulus (P-stimulus) is a stimulus whose effect on our psyche occurs at a value below the threshold value. Threshold is the minimum intensity of a stimulus at which we become aware of its presence. P-stimuli can be auditory, visual, tactile, or even odors that do not cause us to consciously respond but still have an impact on our behavior and emotional state.

Research into subthreshold stimuli shows that they can have a significant impact on our psyche and behavior, despite the fact that we are not aware of their presence. For example, subthreshold auditory stimuli can cause subtle feelings of anxiety or discomfort, which can affect our performance, concentration or mood. Subliminal visual stimuli can subconsciously influence our perception of the environment or cause emotional responses of which we are unaware.

One area where the use of subthreshold stimuli is of particular interest is advertising and marketing. Advertising agencies and companies are exploring the possibility of influencing the subconscious mind of consumers using subliminal stimuli. Some research suggests that subliminal messages or images can enhance advertising effectiveness and influence consumers' choices, even if they are not aware of the reason for their choice.

However, the use of subthreshold stimuli raises ethical questions. Subconscious influence on people's behavior and decisions can be perceived as manipulation or a violation of personal freedom of choice. Some countries even ban the use of subthreshold stimuli in advertising and other areas to prevent potential abuse.

Overall, subthreshold stimuli represent an interesting research field that continues to generate debate and discussion. The effectiveness, ethics, and potential impact of subthreshold stimuli require further research and discussion. Understanding and being aware that we are exposed to stimuli even without our conscious awareness can help us be more aware and more protected from external influences.

In conclusion, a subthreshold stimulus (P-stimulus) is a stimulus whose effect on our psyche occurs at a magnitude below the threshold value. They can influence our behavior and emotional state, despite the fact that we are not aware of their presence. The use of subthreshold stimuli has attracted interest in various fields such as advertising and marketing, but ethical questions have also arisen regarding their use. Further research and discussion will help us better understand the effects of subthreshold stimuli and develop ethical guidelines for their use.



Articles - The magnitude of a signal that does not cause sensation (lat. minimus minimi) - P, (magnitude of stimulation): receptor excitation that is insufficient to cause sensation; physiological threshold of sensitivity.

A subthreshold stimulus irritates the receptors, but its effect goes unnoticed because it is below the sensitivity threshold of the receptors. Such weak stimuli include subtle musical sounds, the ticking of a wristwatch, subtle light signals, and infrasounds against a background of noisy background music. Subthreshold stimuli can also be physical manifestations of electrical activity in the brain, such as background neural fluorescence and ocular nystagmus. Examples in other areas of research include detection of nearby sound sources in urban environments and simple stimuli in myocardial scintigraphy.



Introduction

A subthreshold stimulus is a person’s perception of stimuli that are below the threshold of sensitivity of his senses. The concept of a subthreshold stimulus was first introduced in 1972 by behaviorists J. Taylor and R. Excell. It was they who conducted experiments proving that small fluctuations in stimuli can have a significant impact on human behavior.

The concept of a subthreshold stimulus is of particular importance for psychologists, since it can play an important role in the formation of behavioral reactions and mental states of a person. For example, small changes in the noise level in a room can affect a person's mood, as well as reactions to external stimuli



- Subthreshold irritant - a psychological phenomenon of increased sensitivity to light: the appearance of a sensation (visual discomfort) when the intensity / brightness of the light flux exceeds the threshold of physiological sensitivity of the photoreceptor cells of the retina (biological photodetectors) and the subject has a reaction to brightness unevenness in the field of view. This is because the human eye has a low threshold sensitivity to subtle changes in brightness, similar to how many people notice a faint unpleasant odor that most others will ignore. This feature of human physiology makes it sensitive to fluctuations in brightness emitted by the Sun or observed as a star in the night sky, which would otherwise be indistinguishable. However, the cause and effect of the concept of subthreshold stimulus is still controversial among scientists. In modern science, the problem of the presence of peripheral light synesthesia is of interest to many cognitive psychologists and neuroscientists. One approach is to test the hypothesis of a functional relationship between peripheral synesthesia and the activity of the neocortex, which is thought to be responsible for processing sensory information. In other words, connectomic studies often compare the conditions of subjects with possible manifestations of peripheral light synaesthetics and the conditions of people diagnosed with aphasia. These studies show some differences in the activity of certain parts of the brain, even if such differences are quite small between people with peripheral visual disorder and the general population. However, they cannot give a complete picture of whether peripheral light synesthesia should be classified as a disease, which may be supported by the effect of restoring the functions of the visual analyzer after some specialized exercises of the optic nerve. It can be assumed that the peripheral shade of color perception is provided by the activity of some neurons located on the periphery of the optic tract, and not beyond the retial columns in the primary visual cortex or language areas, and neither the correction of their functionality nor the suppression of their activity reduces the likelihood of the emergence of new subjective phenomena . This influence could be associated with physical pathology of body structures involved in the processes of transmitting external visual information to the brain, or changes in a person’s lifestyle.
