Wireless Physiology | Psychophysiological Measures of Emotion

wireless physiology
Emotional reactions influence, and may help predict, our decisions and offer valuable information for communication and neuromarketing researchers, but emotion is difficult to measure explicitly. Emotional responses are complex phenomena consisting of multiple components, including evaluation/appraisal, subjective feeling, expression, and physiological reaction. This mix of components is difficult to measure. Researchers can interview or survey participants about their feelings—typical measures include traditional Likert-type questions, open-ended questions, or pictorial scales—but self-reporting doesn’t easily convey true or complete emotional response. Self-reporting is further complicated by the fact that participations often choose different terms to describe their feelings or respond that they feel nothing. Blending self-assessment with physiological changes that reflect visceral responses provides an unfiltered representation of emotion.
 
Sympathetic nervous system (SNS) activity provides objective data for assessing emotional reactions. Electrodermal Activity (EDA) is a popular SNS measure. EDA is basically an index of the electrical activity of the skin; sweat glands in the skin are filled with tiny amounts of sweat and sweat contains ions that conduct current, which can be detected and recorded. Increases in EDA reflect increases in sympathetic nervous SNS activity. EDA is also referred to as skin conductance (SCR, SCL, etc.) or galvanic skin response (GSR).

wireless wearable devicesSignificantly, EDA can provide time-stamped information for moment-to-moment reaction measurement throughout a message/stimulus presentation (such as an advertisement).Combining physiological data with self-reported data helps provide a more complete, more accurate understanding of a participant’s emotional reactions. Unobtrusive, wearable wireless physiology devices (such as BioNomadix BN-PPGED from BIOPAC Systems, Inc.) can provide continuous and precise measures of nervous system activity, such as EDA, ECG, and RSP.

Read a case study at “Hooked on a Feeling: Implicit Measurement of Emotion Improves Utility of Concept Testing.” Researchers conducted a message-testing study in which they measured physiological arousal (via EDA), emotional valence (via continuous rating dial data), and discrete emotions (retrospectively reported emotional reactions), among other measures. Researchers used a BIOPAC MP150 data acquisition system and wireless EDA BioNomadix module to collect EDA while participants viewed each ad, and a BIOPAC variable assessment transducer to assess in-the-moment feelings of positivity or negativity. E-Prime was used to allow for precise synchronization across stimuli presentation and data collection.

Neuromarketing Solutions | Data Acquisition

Neuromarketing
Neuromarketing solutions are available that allow you to examine physiological responses to products, environments, other stimuli or decision making tasks. Multiple physiological signals can be recorded and analyzed for Neuromarketing, including EEG. EEG analysis options allow for understanding of the subject's cognitive state for a variety of Neuromarketing tasks.  Gauging level of engagement, workload and drowsiness while performing tasks or participating in consumer test situations can provide valuable insight into product development and marketing. Neuromarketing solutions should be as unobtrusive as possible, allowing for wireless EEG and other physiological signals to be recorded and analyzed from mobile subjects. Whether subjects are in a lab or real-world environment, users should have the ability to stream physiological data live or record and log up to 32-channels of high-quality biopotential data.


neuromarketing
For some applications, long-term activity studies may be necessary. Solutions are available that allow users to monitor subjects in their home environment over multiple hours or days. For example, record ECG, EEG, Respiration, EMG, and GPS positioning data to look at overall activity levels and physiological responses to different Neuromarketing stimuli and daily activities that include product interactions.

Virtual Reality & Neuromarketing

Immersive virtual reality environments can unlock physical boundaries and budget limits.
Applications for VR protocols are varied and include Psychology, Ergonomics, Neuromarketing & Neuroeconomics (Consumer Research), Biomechanics & Kinesiology, Healthcare, Computer Modeling/Simulation, Education, and Training: hazard, medical, etc.
virtual reality
Researchers can immerse subjects in a VR world and record physiological data as the virtual environment influences the subject. A feedback loop can be included for greater control and automation of the VR world. This allows the world to change in real time, based on the subject’s responses. Timing events are used for analysis of the physiological data. Eye tracking can be added to the headmounted VR display to track the subjects’ eyes as they view the immersive environment during the experiment, and position tracking can also be included.


Wireless transmitters, EEG caps, and eyetrackers have been used to capture data from mobile subjects in actual environments, but virtual reality expands the research potential by allowing participants to be immersed in variable, simulated environments with an incredible degree of realism. For instance, neuromarketers can allow subjects to smell and feel multiple products and move through different display configurations, or psychologists can choose appropriate environments to study phobias such as flying or public speaking.
At the first Neuromarketing World Forum (2012, Amsterdam), the challenge and potential of enhancing market research with neuromarketing tools was discussed, and virtual reality immersive techniques were recognized as valuable tools for measuring affective states while modifying product presentation. The value of capturing synchronized physiological data (heart rate, HR, ECG, EDA), brain response (EEG, fMRI, fNIR), and behavior metrics (eye tracking, position tracking) was also discussed.
Turnkey VR/ Immersive systems from BIOPAC are easily combined with wireless physiology data to synchronize VR events with physiological response data. Neuromarketers and other researchers can record any combination of signals (ECG, EEG, EOG, EMG, EGG, EDA, temperature, respiration, pulse, etc.) and include multimodal stimulation with visual, auditory, olfactory, haptic, or electric stimulus. Remote Monitoring options provide subjects with a greater degree of freedom and allow them to move around within the virtual world.

Neuromarketing and Neuroeconomics | Data Acquisition

Neuromarketing and neuroeconomics research use physiological data to examine a participant’s response to a product, service, or decision making task. Researchers combine cognitive, sensorimotor, and affective responses to marketing stimuli from advertisements to political debates.


neuromarketing research
Physiological signals for macroeconomic or micromarketing analysis can be recorded almost anywhere, including: the lab, during fMRI, a workplace environment, virtual reality scenarios, in a subject's home, or mobile application. Wireless data systems allows participants to move and respond freely.

A wide range of recording options can ensure quality data collection in a comfortable and unobtrusive manner to seamlessly capture the most important events in a neuromarketing and neuroeconomic study.
Examine responses to stimuli or decision making tasks in the brain with EEG or fNIR data. Analyze cognitive state, level of engagement, workload and drowsiness while subjects participate in a consumer test, perform a task, watch a presentation, etc.

Record a variety of biometrics to examine stress and arousal to specific stimuli, such as facial EMG, ECG/Heart Rate, skin conductance level (EDA/GSR), or respiration.
Combine eye tracking data with other physiological variables to provide context for the subject's emotional response to certain types of stimulation.

Synchronize with video to visually correlate subject’s behavior with the data...replay the video and see what the subject was doing at key points during neuromarketing study. Synchronize with GPS data to better understand a subject’s lifestyle. Create reports that classify specific and non-specific response events to specific stimuli results from automated scoring and analysis software that helps to measure, score, and output experiment results.
