  • IROS - Influence of auditory and visual modalities on Skin Potential response to robot motions
    2004 IEEE RSJ International Conference on Intelligent Robots and Systems (IROS) (IEEE Cat. No.04CH37566), 2004
    Co-Authors: N. Hanajima, M. Fujimoto, H. Hikita, M. Yamashita
    Abstract:

    This paper addresses the issue of investigating the relationship between Skin Potential response (SPR) and robot motion from the aspect of auditory and visual modalities. The motion of the robotic devices primarily gave stimulus to the human through the auditory and visual modalities. Our previous work indicated that actuation noise caused from the robots tended to raise the sympathetic nerve system response of the heart rate variability. However, it was difficult to evaluate instantaneous response corresponding to a specific stimulus using the HRV. The SPR is possible to reflect the instantaneous response to the stimulus. In the experiment, we controlled the conditions of the visual and/or auditory modalities by blocking out the sound and sight from the robot, a manipulator with 5 D.O.F. We also changed the position of the robot around subjects for stimuli variety. As the result, it is shown that the SPR magnitudes, under the condition of blocking out not only the sound but also the sight from the robot, tended to be significantly lower than without blocking.

  • Simultaneous measurement of electrodermal activity components correlated with age-related differences
    Journal of Biological Physics, 2020
    Co-Authors: Dindar S. Bari, Haval Y. Yacoob Aldosky, Ørjan G. Martinsen
    Abstract:

    Electrodermal activity (EDA) measurements are influenced by various factors. Age-related psychological and physiological changes may be considered as one of the possible factors which may influence EDA measurements. In order to properly investigate the effects of such factors on EDA, techniques of precisely and simultaneously recording more than one EDA parameter are recommended. This study aims to explore the impact of age-related differences on EDA components through employing a new measuring technique, which is composed of a small front-end electronic box, DAQ card, and a laptop running LabVIEW software. It is dependent on the simultaneous recording of three EDA parameters: Skin conductance (SC), Skin Potential (SP), and Skin susceptance (SS) at the same Skin site. EDA components as results of breathing, mathematical tasks, and image stimuli were recorded from 60 healthy participants simultaneously at the same Skin site. They were categorized by age into young adults (ages 18–25), middle-aged adults (ages 30–40), and old adults (ages 50–70) years. It was found that Skin Potential responses (SPRs), and Skin conductance level (SCL) ( p   0.05). Moreover, both tonic and phasic SS were the least affected and found to be more robust than SC and SP with respect to aging. The study suggests that it is important to take age into account in research studies where the mean aim of the study is to compare EDA parameters; however, in the meantime, the results from our small number and specific study population cannot be generalized to clinical applications.

  • Electrodermal responses to discrete stimuli measured by Skin conductance, Skin Potential, and Skin susceptance
    Skin Research and Technology, 2017
    Co-Authors: Dindar S. Bari, Haval Y. Yacoob Aldosky, Christian Tronstad, Håvard Kalvøy, Ørjan G. Martinsen
    Abstract:

    BACKGROUND/AIM: Presently, electrodermal activity (EDA) is the preferred term for changes in electrical properties of the Skin. Change in the Skin conductance responses (SCRs) and Skin Potential responses (SPRs) due to external stimuli have previously been investigated in a number of studies, but very little for Skin susceptance responses (SSRs) recorded simultaneously at the same Skin site. This study aimed to investigate the association between the three parameters of EDA, Skin conductance (SC), Skin Potential (SP), and Skin susceptance (SS) responses generated by different types of psychological stimuli. METHODS: SCRs, SPRs, and SSRs were recorded from 20 healthy test subjects simultaneously at the same Skin area. EDA responses were induced by five different external stimuli, which were shown in the form of PowerPoint slides on a PC monitor that situated in front of participants. RESULTS: All stimuli evoked EDA responses, but with significantly different magnitudes, dependent on stimulus type. Both SC and SP waveforms yielded positive responses with respect to the stimuli; however, SS showed negative response and its role was found to be significant at low frequency (20 Hz). CONCLUSIONS: This study illustrated that different discrete stimuli showed different passive and active electrodermal responses at the same Skin site. SCRs, SPRs, and SSRs were dependent on the stimulus type, and the highest response was associated with the sound stimulus, which can be attributed to orienting response or startle reflex. In addition, it was found that the SSRs have a significant contribution at 20 Hz. In spite of a high correlation found between average amplitude values of SCRs and SSRs, no significant association was seen between average amplitudes values of SPRs and SSRs, and between SCRs and SPRs.

  • Waveform difference between Skin conductance and Skin Potential responses in relation to electrical and evaporative properties of Skin.
    Psychophysiology, 2013
    Co-Authors: Christian Tronstad, Håvard Kalvøy, Sverre Grimnes, Ørjan G. Martinsen
    Abstract:

    The shapes of Skin conductance (SC) and Skin Potential (SP) responses are often similar, but can also be very different due to an unexplained cause. Using a new method to measure SC and SP simultaneously at the same electrode, this difference was investigated in a new way by comparing their temporal peak differences. SC, SP, Skin susceptance (SS), and transepidermal water loss (TEWL) were recorded from 40 participants during relaxation and stress. The SP response could peak anywhere between the onset of an SC response to some time after the peak of an SC response. This peak time difference was associated with the magnitude of the SCR, the hydration of the Skin, and the filling of the sweat ducts. Interpretation of the results in light of existing biophysical theories suggests that this peak difference may indicate the hydraulic capacity state of the sweat ducts at the time of a response.
