Summary: Human perception of touch is influenced by inputs from multiple channels. Contrary to classical theories, it was found that inputs from two sub-modalities of mechanical input channels interact to determine tactile perception. Sustained mechanical pressure was shown to inhibit tingling sensations induced by a bioactive compound, without mediation from nociceptive or affective channels.

Summary: This study proposes a flexible tactile sensor based on fiber optic grating for detecting normal and shear forces, aiming to facilitate the acquisition of tactile information. By deliberately embedding fiber Bragg gratings (FBGs) at off-axis positions of a cylindrical silicone elastomer, the sensor achieves high sensitivity, real-time response, and good stability. Experimental results demonstrate that the flexible tactile sensor is capable of simultaneous temperature and normal force or shear force measurement, providing a new approach for multi-dimensional tactile sensing.

Summary: This research aims to detect the light touch contact between a robot manipulator and objects using vibration sensors. By analyzing the Fourier spectra of low-frequency vibrations and accelerometer data, researchers attempt to identify the changes in vibration propagation patterns under different gripping properties. Additionally, through the collection and analysis of vibration feedback data, the research aims to lay the groundwork for pattern extraction and recognition based on the physical properties of an object.

Summary: This study utilized a multi-channel convolutional neural network (MCNN) to detect faults in wind turbine blades and blade angles. The proposed approach effectively captures fault characteristics from original vibration signals and identifies their state using multiple convolutional neural network (CNN) models. The results obtained from each model are combined using a maximum output network (MAXNET) to compute the most accurate state. The proposed approach achieved a high identification accuracy of 87.8% for four fault types in large wind turbine blades.

Summary: The study showed that patients with FND do not exhibit a stronger placebo response compared to healthy controls, suggesting that increased suggestibility to placebo in FND patients may be a misconception. Instead, occasional dramatic placebo responses may occur due to the inherent variability of functional symptoms compared to organic diseases.

Summary: The study explores decision reversals that involve integrating multiple classes of information, such as sensory evidence, higher-order intentions, and motor costs. Movement trajectories reveal when participants change their mind about dot-motion direction and colour choices. Results show that decision reversals about colour intentions are less frequent in participants with stronger intentions and lower motor costs for intention pursuit.

Summary: This study conducted a psychophysical experiment to investigate the quality and magnitude of the illusory sensation felt during the velvet hand illusion (VHI). It was found that as the intensity of the illusory sensation increased, the tactile sensation became softer, wetter, warmer, and more favorable, resembling leather and fabrics rather than metallic wire. These findings provide a better understanding of VHI and tactile texture perception.

Summary: Reasoning about underlying causal relations influences responsibility judgments, with a preference for pluralistic causal reasoning. Dependence theories and transference theories are two main approaches in causal reasoning, and hybrid models combining both have emerged. Our experiment findings indicate that diminished responsibility judgments occur when dependence, transference, or both fail.

Summary: This study aimed to test whether patients with functional tremor exaggerate their symptom perception and reporting. The results showed that compared to patients with organic tremor and healthy controls, patients with functional tremor did not perceive or report their tremor to be exaggerated.

Summary: This paper introduces a non-contact, temperature-controlled, multi-purpose cooling stimulator, which can precisely control the cold sensation stimulation and be used to study different aspects of cold sensation. It avoids the interference of mechanical contact. Through experiments, it is verified that this method can measure the cold detection threshold without mechanical contact, providing a more accurate method for studying cold sensory pathways and cold-touch interactions.

Summary: Research shows that people's perception of freedom is influenced by their behavioral tendencies, even when their choices are biased by habits. This illusion of freedom artificially increases the sense of freedom and has important implications for understanding mechanisms of persuasion.

Summary: In cases of rape and sexual assault, victims often experience a state of immobility referred to as 'freezing'. Neuroscientific research suggests that this freeze response is a result of fear and threat, which can inhibit the brain circuits responsible for voluntary movement. Thus, defense arguments that blame victims for freezing are inappropriate and unfair.

Summary: The study proposes a rotating-frame method to modulate tactile textures for various materials, resulting in the perception of different textures. The method alters the tactile textures of touched materials, making them appear softer, smoother, slipperier, and warmer. This method provides a simple technique for texture augmentation without disrupting direct contact between the hand and materials.

Summary: This study investigated the possibility of offering pseudo-haptic feedback to a user manipulating a virtual object using keystrokes. The speed of the cursor within a square area was found to be the most important determinant of perceived resistance, and resistance could be generated visually even without user's keystrokes.
