Background: Social rejection elicits negative mood, emotional distress and neural activity in networks that are associated with physical pain. However, studies assessing physiological reactions to social rejection are rare and results of these studies were found to be ambiguous. Therefore, the present study aimed to examine and specify physiological effects of social rejection.Methods: Participants (N = 50) were assigned to either a social exclusion or inclusion condition of a virtual ball-tossing game (Cyberball). Immediate and delayed physiological (skin conductance level and heart rate) reactions were recorded. In addition, subjects reported levels of affect, emotional states and fundamental needs.Results: Subjects who were socially rejected showed increased heart rates. However, social rejection had no effect on subjects skin conductance levels. Both conditions showed heightened arousal on this measurement. Furthermore, psychological consequences of social rejection indicated the validity of the
These sites are chosen because of the high density of eccrine sweat glands, meaning an increased ability to detect changes in skin conductance. That being said, there are eccrine sweat glands all over the human body, so it is possible to measure skin conductance at many other sites. One example would be the soles of the feet, which are commonly used when dealing with babies.. With MindWare equipment, conductance is measured by applying a low DC voltage across the skin and measuring how the current changes.. It is also critical to recognize the difference between electrodes used to measure electrodermal activity and those used to measure other common physiological signals such as ECG. MindWare Electrodes used for EDA are rectangular in shape, and have a different electrode gel concentration (0.5% chloride wet gel). The ion concentration in the gel is designed to be similar to the ion concentration in sweat. Higher ion concentrations found in ECG electrodes will saturate the eccrine glands and ...

Eighteen healthy normal weight female volunteers were recruited. The stimulus materials consisted of pretested pictures which each had 2 features, valence (positive/negative) and category (food/nonfood). Pleasantness ratings and psychophysiological responses, including facial electromyography, heart rate variability (HRV), galvanic skin response (GSR), and gaze deviation, were recorded. The main findings were as follows: (a) Corrugator muscle activation and GSR ...
An Overview Of Clinical Biofeedback. 1) Treatment Type: This is a specialized form of Behaviour Therapy (Behaviour Modification).. 2) Aim: To train patients to self-regulate, to some extent, physiological processes: heart rate, blood volume pulse, vasodilation/ vasoconstriction, muscle tension, brain waves (EEG), galvanic skin response (GSR), and respiratory patterns.. 3) Methods: Electronic, and other mechanical devices are used to monitor the patients physiological processes, such as subtle muscle tension.. 4) Patients are provided real-time feedback about the ongoing physiological processes (biofeedback).. 5) Classical and Operant Conditioning methods are used to train the patients to modify physiological responses, e.g. to induce relaxation by breathing comfortably at 10 breaths per minute over a 15 minute several times a week. This is complimented by home practice, with or without biofeedback devices.. 6) In general, the interventions help to achieve Autonomic Nervous System balance ...
The recent increase in interest for online multimedia streaming platforms has availed massive amounts of multimedia information for everyday users of such services. The available multimedia contents need to be indexed to be searchable and retrievable. Towards indexing multimedia contents, user-centric implicit affective indexing employing emotion detection based on psycho-physiological signals, such as electrocardiography (ECG), galvanic skin response (GSR), electroencephalography (EEG) and face tracking, has recently gained attention. However, real world psycho-physiological signals obtained from wearable devices and facial trackers are contaminated by various noise sources that can result in spurious emotion detection. Therefore, in this paper we propose the development of psycho-physiological signal quality estimators for uni-modal affect recognition systems. The presented quality adaptive unimodal affect recognition systems performed adequately in classifying users affect however, they ...
A well-documented problem of sex-offender assessment is dissimulation in the form of defense responding on three instruments widely used for this population: (a) Minnesota Multiphasic Personality Inventory-2 (MMPI-2), (b) Multiphasic Sex Inventory-2 (MSI-2), and (c) Penile Plethysmograph (PPG). Although the MMPI-2 and the MSI-2 both consist of reliable validity scales, validity indices continue to be researched for the PPG. Response interference is a term that can be used to describe numerous causes for low-level responses on response interference indicators of the Monarch PPG and includes event markers, penile response, galvanic skin response, respiration, and respiration amplitude. Convergent validity data are suggested when assessing sex offenders; therefore, it would be useful to identify corresponding indicators of defensiveness. The purpose of this study was to utilize empirically established validity scales of the MMPI-2 and MSI-2 to investigate response interference or defense responses on the

The combination of single-switch access technology and scanning is the most promising means of augmentative and alternative communication for many children with severe physical disabilities. However, the physical impairment of the child and the technologys limited ability to interpret the childs intentions often lead to false positives and negatives (corresponding to accidental and missed selections, respectively) occurring at rates that frustrate the user and preclude functional communication. Multiple psychophysiological studies have associated cardiac deceleration and increased phasic electrodermal activity with self-realization of errors among able-bodied individuals. Thus, physiological measurements have potential utility at enhancing single-switch access, provided that such prototypical autonomic responses exist in persons with profound disabilities. The present case series investigated the autonomic responses of three pediatric single-switch users with severe spastic quadriplegic cerebral palsy

00 if they were sure that they would receive an electrical stimulation, and near 50 if they were unsure. Responses were recorded throughout the experiment and sampled at 40 Hz. We then averaged the values across the last four seconds of the stimulus period for each trial. These Baicalein 6-methyl ether side effects averages were then used in subsequent group level analysis.Skin conductance responsesWe recorded skin conductance level (SCL) via two surface cup electrodes (silver/silver chloride, 8 mm diameter, Biopac model EL258-RT, Goleta, CA) filled with electrolyte gel (Signa Gel, Parker laboratories Fairfield, NJ) attached to the bottom of the participants left foot approximately 2 cm apart. SCL was sampled at 200 Hz throughout the experiment. We identified the peak SCL value during the 8-s trial and expressed it as a percent change from the average of the preceding 2-s baseline (Balderston and Helmstetter, 2010; Balderston et al., 2011). These values were used in subsequent group level ...

Subjects reported higher self-ratings of helplessness, lack of control, tension, stress, unhappiness, anxiety, and depression; had greater hypothalamic-pituitary-adrenal axis function as measured by elevations in plasma adrenocorticotropic hormone; and had higher levels of sympathetic nervous system and electrodermal activity after the uncontrollable stress condition than after exposure to controllable stress. Thus, lack of control over even a mildly aversive stimulus can produce alterations in mood as well as neuroendocrine and autonomic nervous system ...

Knowledge of the mental workload induced by a Web page is essential for improving users browsing experience. However, continuously assessing the mental workload during a browsing task is challenging. To address this issue, this paper leverages the correlation between stimuli and physiological responses, which are measured with high-frequency, non-invasive psychophysiological sensors during very short span windows. An experiment was conducted to identify levels of mental workload through the analysis of pupil dilation measured by an eye-tracking sensor. In addition, a method was developed to classify mental workload by appropriately combining different signals (electrodermal activity (EDA), electrocardiogram, photoplethysmo-graphy (PPG), electroencephalogram (EEG), temperature and pupil dilation) obtained with non-invasive psychophysiological sensors. The results show that the Web browsing task involves four levels of mental workload. Also, by combining all the sensors, the efficiency of the
The conceptual validity of kinetic gait analysis and disability outcome assessment methods has guided their use in the assessment of pain caused by osteoarthritis (OA). No consensus on the best clinical methods for pain evaluation in canine OA exists, particularly, when evaluating treatments where a smaller treatment effect is anticipated than with pharmacological pain killers. This study thus aimed at determining the technical validity of some clinical endpoints on OA pain in dogs using the green-lipped mussel (GLM)-enriched diet. Twenty-three adult dogs with clinical OA completed the prospective controlled study. All the dogs were fed a balanced diet over a 30-day control period followed by a GLM-enriched diet over a 60-day period. The kinetic gait analysis parameter (PVFBW, peak vertical force adjusted for body weight change), electrodermal activity (EDA), and a standardized multifactorial pain questionnaire (MFQ) were performed on day (D) 0 (inclusion), D30 (start) and D90 (end).

Bipolar disorder is regarded as a disorder of mood and initial studies have focused on structural abnormalities in limbic networks, known to subserve mood. More recently, functional imaging studies allude to affect processing deficits, which may involve frontostriatal networks. This study sought to explore disturbances in networks involved in the processing of negative affect in euthymic bipolar patients. We used simultaneous functional magnetic resonance imaging and galvanic skin responsivity to explore disturbances in these networks. When processing negative affect, controls recruited a distributed subcortical-prefrontal network. In contrast, patients could only activate a subcortical network that included the amygdala and hippocampus. This study provides evidence for a disconnection in the transfer of information within frontostriatal networks in bipolar disorder. © 2007 Lippincott Williams & Wilkins, Inc.
We follow a multimethod approach using quantitative as well as qualitative methods to investigate various socio-psychological mechanisms in crowds, such as social influence, emotion, or social norms. Our data include questionnaire ratings, physio-psychological data (e.g. heart rate, skin conductance level) and interview transcripts obtained through experiments, field studies and interviews.. In the early stages, pedestrian dynamics research has mainly focused on modeling and the empirical analysis of physical aspects of moving crowds. During the last years, however, the social psychological perspective has been more and more integrated to get a more comprehensive picture crowds - viewing its participants as moving particles and social beings embedded in a cultural context.. Within the wide field of social psychology in pedestrian dynamics, we concentrate on four clusters of research questions:. ...
answer Dr. Barnes:According to a review article by Dr. Jevning and his colleagues (Neuroscience and Biobehavioral Reviews, 1992), the Transcendental Meditation experience appears to elicit a physiological state characterized by a wakeful hypometabolic integrated response. Research has reported a decreased metabolism of the peripheral muscles and red cells, as well as decreased stress hormone secretion. These qualities consistent with deep rest have also been measured using EEG. Additionally, findings of reduced respiratory rates, blood lactate levels and skin conductance levels have been reported.. In other words, the Transcendental Meditation technique allows us to experience a simpler, more settled form of awareness, reducing levels of stress hormones. Effects of chronic stress on hormone levels have been well documented. Acute effects on stress hormone secretion are consistent with decreased activation during meditation. Chronic decrease of this level of activation may also occur. According ...

Events that violate expectations are biologically significant and accordingly elicit various physiological responses. We investigated the functional relationship between three of these responses: the P300, the Novelty P3 and the pupil dilation response (PDR), with a particular focus on their co-variance with reaction time and measures of subsequent memory. In a modified Novelty P3 oddball paradigm, participants semantically categorized a sequence of stimuli including (1) words of a frequent category, (2) words of an infrequent category (14% of the trials) and (3) pictures of the frequent category (14% of the trials). The Novelty P3 oddball task was followed by a recall- and a recognition test. Larger amplitudes of the P300, identified by a spatial principal component analysis (PCA), were associated with enhanced subsequent recall as well as faster reaction times during the recognition test, suggesting a close relationship between the cognitive process indexed by the P300 and memory encoding. The PDR was

This may be demonstrated using a simple experiment. For instance, a group of ten students are blindfolded and are made to sit in a circle. A heavy object is now dropped in the middle, which creates a big noise and vibration. As an effect of this, it is most likely to observe that the reaction by all the students in the room would be similar, yet quite different. While the input of the signal provided in this case is the same in all the cases, it is evident that the manner, in which it is perceived by the brain and processed in the form of a response, will vary from person to person. While some of them could be startled with a jerk, some might even scream as a reflex reaction to it. It might not be surprising to spot a fraction of the group which might not be even moved by this change or loud impact. This is the extent to which a response can vary on exposure to a stress stimuli which is discernable from the usual surroundings. Also, the time of recovery for each individual could be different. ...
Fearfulness as a temperament dimension is already evident in infants. Children who vary in fearfulness differ in their behavioural and physiological reactivity to novel situations. Despite evidence linking the extremes of early fearful temperament to later psychopathology, information regarding its development and correlates is lacking. The present research examined fearful temperament in infancy through assessments of behaviour and physiology, and compared this information with maternal reports. The proposed associations between fearfulness, sustained attention and of effortful control were also investigated. Temperament was examined longitudinally in 50 healthy infants in the 1st and 2nd year of life. Mothers reported on their childrens fearfulness behavioural distress during fear provocation, and resting and stress levels of skin conductance activity (SCA) and Cortisol were examined. Skin conductance responses (SCRs) during an Orienting Habituation Paradigm (OHP) were also studied. We ...
Four patients with functional hemispherectomy, one patient with a complete anatomical hemispherectomy, and one patient with unilateral removal of the temporal, parietal and occipital lobes took part in two sets of experiments designed to investigate their residual sensitivity to motion-in-depth in the hemianopic visual field. Two types of computer-generated visual displays were used; in the first set of experiments, a dot pattern and in the second, a circular checkerboard. These simulated either convergent, divergent or reversed rotational motion. Each set of experiments consisted of two parts; in the first part, electrodermal responses were monitored during stimulus presentation while the subjects performed a simple distracting task. In the second part, subjects were asked to state verbally the direction of stimulus motion. Contrary to expectations, no reliable changes in skin conductance were elicited from any of the subjects by changes in the direction of motion of the component parts of either the

This is the last major work of Eugene N. Sokolov, Professor of Psychophysiology at Moscow State University from 1950 to 2008. It summarizes the contributions of a lifetime on the neural mechanism of consciousness. Working at the intersection of psychology, neurophysiology and mathematics, Sokolov early introduced the concept of quantifiable difference in neuronal activity and cognitive distance as corresponding metrics in the physical and mental models of reality.
This dataset includes pupil size response (PSR), skin conductance response(SCR), electrocardiogram (ECG) and respiration measurements for each of 20 healthy unmedicated participants (8 males and 12 females aged 22.8+/-3.3 years) participating in a classical (Pavlovian) discriminant delay fear conditioning task. (One additional participant in the initial sample in Korn et al. (2017) - but who did not finish the experiment and was not included into the analysis - is not contained in this dataset.)

New UK research shows that biofeedback, a technique using skin conductivity detection technology to train the mind to control physiological responses, can reduce seizure frequency.. Biofeedback is safe, easy to learn, and non-invasive and has been used previously as an EEG based technology with patients with epilepsy The type of biofeedback used in this study is a technology patented by Dr. Yoko Nagai of University of Sussex medical school called electrodermal (EDA) biofeedback. Patients attach small sensors to their two middle fingers. A small electrical current measures electrical conductance on the skin surface.. As patients view an animated computer programme their skin conductance drives the screen forward and alters the animation, a rewarding task similar to a video game.. The goal of this biofeedback approach, called autonomic cognitive rehabilitation therapy, is to generate new reactions of a physiological and psychological nature. With practice, patients start to anticipate seizure ...
Background: Working while exposed to motions, physically and psychologically affects a person. Traditionally, motion sickness symptom reduction has implied use of medication, which can lead to detrimental effects on performance. Non-pharmaceutical strategies, in turn, often require cognitive and perceptual attention. Hence, for people working in high demand environments where it is impossible to reallocate focus of attention, other strategies are called upon. The aim of the study was to investigate possible impact of a mitigation strategy on perceived motion sickness and psychophysiological responses, based on an artificial sound horizon compared with a non-positioned sound source.. Methods: Twenty-three healthy subjects were seated on a motion platform in an artificial sound horizon or in non-positioned sound, in random order with one week interval between the trials. Perceived motion sickness (Mal), maximum duration of exposure (ST), skin conductance, blood volume pulse, temperature, ...
Biofeedback has evolved from a fascination in the 1960s and 70s to a mainstream methodology today for treating certain medical conditions and improving human performance. This evolution has been driven by years of scientific research demonstrating that the mind and body are connected, and that people can be taught to harness the power of this connection to change physical activity and improve health and function. Public interest in biofeedback is growing, and with it the need for a clear answer to the question, what is biofeedback? The leading professional organizations representing the field have answered with the following standard definition.. Biofeedback is a process that enables an individual to learn how to change physiological activity for the purposes of improving health and performance. Precise instruments measure physiological activity such as brainwaves, heart function, breathing, muscle activity, and skin temperature. These instruments rapidly and accurately feed back ...
The main aim of the present research was to determine the effectiveness of biofeedback-aided relaxation training (BFRT) for alleviating symptoms of depression, anxiety, and stress for undergraduate students as they prepared for their final examinations. In a randomized controlled trial design, 29 male and female students, with heightened levels of depression, anxiety and stress scores on the Depression, Anxiety, and Stress Scale, were chosen and randomly assigned to BFRT or a no-treatment control condition. Subjects assigned to BFRT received eight sessions of BFRT spaced over 4 weeks, during which they were trained to decrease electromyography (EMG) and respiration rate (RESP) and to increase skin temperature (TEMP).

The operators were experienced electrodermal testers, each having used this procedure in a clinical setting for over 10 years. The four operators provided their own Vegatest machines (Vega Medizinische Geräte, Schiltach, Germany). The machines were set up in the standard manner for evaluating allergic responses,1 with four ampoules of homoeopathic epiphysis D26 and one ampoule of homoeopathic histamine D60 in the testing honeycomb (figure 1). The individual to be tested held a hand electrode, and the Vega probe was placed on the terminal acupuncture point on the lateral aspect of the third toe (the spleen/pancreas meridian).1 In each test the operator measured the skin impedance at this point as indicated in arbitrary units on the galvanometer while the patient held the hand electrode to complete the electrical circuit. Each time a new glass ampoule containing the experimental substance was placed in the Vegatest honeycomb, the operator again measured the skin impedance.. At the beginning of ...

Participants will work in groups where the team worker gets to the solution and helps create new learning methodologies.. During the collaborative process, they will learn how to create a conceptual solution, discuss, make decisions and produce the desired output. During the collaborative process, the drone will be used as an auxiliary means in order for participants to get a better sense of the requirements. Participants will learn how to use ThinkerCad software and by that acquire the skills they can use in other design tasks. During the activity, collaborative parameters will be measured (movements, electrodermal and voice activity), in order to better understand and improve the collaboration process. In ...
Many people confuse allergies with intolerance. Allergies affect the immune system and can cause a variety of reactions including delayed gastro-intestinal symptoms to acute anaphylactic shock. Intolerance is the inability to digest a particular food causing symptoms such as nausea, vomiting and abdominal pain. High Street companies sell expensive tests that cost from £45 to £275 claiming to be able to diagnose allergies and intolerance. These tests do not have any proven medical or scientific worth and give inconsistent results. They include analysis of blood samples, strands of hair, changes in electric current (electrodermal testing) and resistance to pressure applied to ones legs or arms (kinesiology). It is a misconception that these tests are harmless because they misdiagnose food allergy in many people who subsequently risk their health by adopting restrictive diets that are unbalanced, unhealthy, lead to nutritional problems and are unenjoyable.. Dr Ho has received training in ...

localroger,. You are only somewhat correct in your statements. While tasers and stunguns do indeed put out very few milliamps, many inexpensive ones do not have current regulation on the output - they are simply dumping stored power from a capacitor in much the same way as the disposable flash camera setup.. Further, the thought that those capacitors can put out way too much current is only partially accurate. A capacitor in a dead short across a perfect conductor can create a high-amp spike for a very limited duration. However, human skin is far from a perfect conductor. Even in the most conductive scenario (damp skin), skin resistance of two electrodes jammed into your flesh is 10k ohms or more - average is 100k-10Meg ohms (you can verify this with a good ohm meter, btw). Ohms law tells us that at 300V, you will experience anywhere from 30mA to 0.3mA, or less. Somewhat painful, but well below the dangerous or deadly range.. Further, area of application is critical. If you grab a charged ...
