“…In this evaluation method, the rating values may be affected by the participant's expectation that the illusion will occur under all condition. To estimate the baseline of the intensity ratings when participants expected that the illusion would occur, we also adopted the vertically moving wire condition as a control condition, which has been reported not to induce strong illusion [9], [10].…”

“…For the conventional method and control conditions, we adopted a typical two-wire stimulus (Fig. 3A) which was the same as that used in our previous study [10]. We adopted a 50-mm gap between the two wires as the optimal wire condition since previous studies showed that the intensity of the illusory sensation was maximized with that amount of separation [12]- [14].…”

“…1B) induce an unexpected tactile sensation that can be described as "velvety" [9]. We previously investigated the sensation during the VHI by using tactile adjectives [10]. In this study, we investigated several conditions in which the same metallic wires were moved in different ways to produce the VHI with different intensities.…”

Investigation of Tactile Illusion Based on Gestalt Theory

Time-evolving tactile sensations are important in communication between animals as well as humans. In recent years, this research area has been defined as “tactileology,” and various studies have been conducted. This study utilized the tactile Gestalt theory to investigate these sensations. Since humans recognize shapes with their visual sense and melodies with their auditory sense based on the Prägnanz principle in the Gestalt theory, this study assumed that a time-evolving texture sensation is induced by a tactile Gestalt. Therefore, the operation of such a tactile Gestalt was investigated. Two psychophysical experiments were conducted to clarify the operation of a tactile Gestalt using a tactile illusion phenomenon called the velvet hand illusion (VHI). It was confirmed that the VHI is induced in a tactile Gestalt when the laws of closure and common fate are satisfied. Furthermore, it was clarified that the tactile Gestalt could be formulated using the proposed factors, which included the laws of elasticity and translation, and it had the same properties as a visual Gestalt. For example, the strongest Gestalt factor had the highest priority among multiple competing factors.

In order to improve the physical function of athletes under hypoxic training, the authors propose to observe the effect of functional food with active ingredients of polypeptide polyamines in deer antler on the physical function of athletes under ultrasound observation. According to the characteristics of physiological changes during hypoxic training, functional foods containing the active ingredients of polypeptide polyamines in deer antler were selected and given to athletes under simulated hypoxic training, observe the changes of red blood cells (RBC), hemoglobin (Hb), hematocrit (Hct), blood lactic acid, free radical metabolism and immune function of athletes, and musculoskeletal under ultrasound observation, discuss how to improve the physical function and athletic ability of athletes under hypoxic training. Experimental results show that athletes after 6 weeks of hypoxic training, red blood cells and hemoglobin were significantly increased, there was a significant difference compared to the control group ( P < 0.05 or P < 0.01 ). After 6 weeks of hypoxic training, hemoglobin increased by 10.1%, a 5.6 percentage point increase compared to the control group. Conclusion. The antler peptides used by the authors can enhance the effect of hypoxic training.
