“…Presumably, men and women could have more similar tactile sensitivity and adopt more similar greeting modalities in a prevalently urban environment than in a rural environment. Moreover, attitude and expectation toward ritualized nonverbal greetings with same-and opposite-gender counterparts could also vary within and between genders, 14,21,45 potentially limiting the consistent appraisal of what constitutes a strong grip, both among males and females and between them. Furthermore, item 14 shares identical nociceptive mechanism with item 13 ("normal handgrip"), apart from the grip strength.…”

The self-reported Pain Sensitivity Questionnaire (PSQ) is a valid supplement to experimental pain testing. However, the latent constructs determining the originally proposed 1 general score (PSQ-total) and 2 subscores (PSQ-moderate and PSQ-minor) have not been consistently investigated in population-based studies or between genders. Based on a single construct hypothesized by expert knowledge or alternative constructs upon empirical evidence, PSQ structures were explored and confirmed among 4,820 participants aged 18 to 93 years of the Cooperative Health Research In South Tyrol (CHRIS) study. By exploratory factor analysis, we identified 3 alternative sets of PSQ imagined painful situations comprising 14, 10, and 9 items, which displayed simple structures of the rotated factor loadings of direct interpretation. In confirmatory analysis (CFA) of 1 latent factor, the 10-item set yielded acceptable goodness-of-fit overall, better fit than the alternative sets and consistent structural properties between genders. Separate analyses based on 14- and 9-item sets returned considerable correlations between 2 latent constructs. In higher-order CFA with each set, 1 first-order general factor explained a large part of the variances of 2 second-order factors. One dominant construct consistently describes the factorial structure of the PSQ. Averaging across the 10-item set, the PSQ-short score represents a structurally robust, gender-consistent, and practical measure of general pain sensitivity. PERSPECTIVE: One dominant latent construct of general pain sensitivity consistently determines responses to the self-reported PSQ. The PSQ-short score maintains similar psychometric properties to the PSQ-total and between genders. This measure is attractive for large-scale research and clinical screening of pain sensitivity.

“…The V-REP simulator cannot realistically compute grasping with a human hand, so we simulate the handshaking gesture with a ball placed inside the gripper. The ball is defined as a static object not subjected to gravity that, unless stated otherwise, moves up and down according to a 2 Hz sinusoidal signal of amplitude 0.16 m. This frequency is coherent for handshaking according to previous experiments dedicated to the study on handshaking between humans (Tagne et al, 2016 ). Since both objects are collidable, the ball exerts a force on the fingers of the gripper, forcing the arm to move along (see Figure 1 ).…”

Hebbian Plasticity in CPG Controllers Facilitates Self-Synchronization for Human-Robot Handshaking

It is well-known that human social interactions generate synchrony phenomena which are often unconscious. If the interaction between individuals is based on rhythmic movements, synchronized and coordinated movements will emerge from the social synchrony. This paper proposes a plausible model of plastic neural controllers that allows the emergence of synchronized movements in physical and rhythmical interactions. The controller is designed with central pattern generators (CPG) based on rhythmic Rowat-Selverston neurons endowed with neuronal and synaptic Hebbian plasticity. To demonstrate the interest of the proposed model, the case of handshaking is considered because it is a very common, both physically and socially, but also, a very complex act in the point of view of robotics, neuroscience and psychology. Plastic CPGs controllers are implemented in the joints of a simulated robotic arm that has to learn the frequency and amplitude of an external force applied to its effector, thus reproducing the act of handshaking with a human. Results show that the neural and synaptic Hebbian plasticity are working together leading to a natural and autonomous synchronization between the arm and the external force even if the frequency is changing during the movement. Moreover, a power consumption analysis shows that, by offering emergence of synchronized and coordinated movements, the plasticity mechanisms lead to a significant decrease in the energy spend by the robot actuators thus generating a more adaptive and natural human/robot handshake.

“…First the simulated results and then the results with the actual robot are presented. For all experiments, the following CPG time constants are chosen such that the CPG intrinsic frequency can be set around 2 Hz (usual handshaking frequency according to [30]): τ m = 0.35, τ s = 3.5. Fig.…”

Complex tasks require the combination of both discrete and rhythmic movements. Though scientists do not yet agree on the neural architecture involved in both types and in the transition from one to the other, the importance of having robot controllers able to behave rhythmically and discretely is universally recognized. In this paper, a bio-inspired robot controller based on oscillating neurons is proposed to realize both discrete and rhythmic movements and easily transition from one to the other. It is shown that, under certain parameter conditions, the CPG controller behaves like a PID controller. In order to demonstrate the feasibility of controlling both discrete and rhythmic movements, the CPG is applied to the initiation of handshaking, namely, reach towards the human hand and start to shake it. Results show that this architecture is suitable for both discrete and rhythmic movements and can easily transition from one to the other.
