Psychophysiological measures are often used to study emotion and attention responses to stimuli, during exertion,and increasingly, to better understand cognitive processes.

LabScribe Software includes a Experiment Builder

Use the stimulus presentation capabilities of LabScribe software, to show an image, play a sound or a video file, while recording physiological parameters from the subject. Details…


Some of the physiological responses that can be measured include:

ERP: Event Related Potentials:

Various Event Related Studies can be performed using iWorx Equipment.

Symbol Processing in the Blink of an Eye: an EEG Study :
by Isaiah Cushman, Gemma Francisco, Michelle Kang, and Nick Taylor, of Irvine Valley College


EDA: Electrodermal Activity ,

Also known as skin conductance response (SCR), skin conductance Level (SCL) and galvanic skin response, GSR).

EDA can be measured using the following:

EEG: Electroencephalography

EEG can be measured using the following:

EMG: Electromyography

EMG can be measured using the following:

ECG: Electrocardiogram

ECG can be measured using the following:

EOG: Electro-oculogram

EOG can be measured using the following:


Temperature can be measured with:

Heart Rate, (heart rate variability)

Heart Rate can be measured using the following:


Respiration can be measured using the following:

Neuromarketing or Behavior Marketing:

Eye Tracking:

Synchronize data collected with LabScribe and Gazepoint Eye Tracking system.




PK-TA PK-TA: Psychological Physiology System

iWorx Psychological Physiology Solutions provide everything you need to perform professionally developed experiments and exercises demonstrating essential concepts in psychological physiology.

IX-B3G IX-B3G Isolated ECG/EMG/GSR Biopotential Recorder

The IX-B3G recording module allows recording of up to three channels of ECG, EMG or EEG as well as GSR (galvanic skin response).

10-20 EEG systemIX-EEG 10-20 system EEG Recorder

The iWorx EEG system consists of a standard 10-20 Electro-Cap with Ag/AgCl electrodes, integrated EEG amplifier/data recorder with inputs for 2 additional biopotential signals (ECG, EMG, EOG, etc.), a built in galvanic skin response (GSR) amplifier, an event marker channel (hand-held push button switch or foot reaction switch) and LabScribe acquisition and analysis software with dedicated EEG module.

Eye TrackingA-iTRAX Eye Tracking Add-on Set

The A-iTRAX extends iWorx Psychology Systems, with Eye Tracking.

Record eye tracking information, along with physiological data from any iWorx Recorder. Visualize and analyze subject reactions to various visual stimuli.

IX-B3G IX-GSR Isolated GSR Recorder

The IX-B3G recording module allows recording of one channel of GSR (galvanic skin response).

Psychological Test

Psychological Test:

Stroop Test: The Stroop Effect demonstrates how interference causes the brain to experience a slower processing time because it is trying to sort through conflicting information it is receiving from outside sources

Eriksen Flanker Test : The flanker paradigm has been used to investigate what factors may affect selective attention and the extent to which processing of irrelevant information occurs.

The Gaze Cue Paradigm : Friesen and Kingstone (1998) showed that incongruent gaze cues, ones that show the gaze looking away from where you want the subject to look, could actually slow down responses to a task, suggesting that gaze cue stimuli could automatically shift attention away from the target object.

Prepulse Inhibition: Prepulse Inhibition (PPI) is a neurological phenomenon in which a weaker prestimulus (prepulse) inhibits the reaction of a subject to a subsequent strong startling stimulus (pulse). The stimuli are normally acoustic, but tactile stimuli, such as air puffs onto the skin and light stimuli, can also be used.

Posner Cueing Task :The Posner Cueing Task, also known as the Posner paradigm, is a psychological test used to assess attention and attention deficit.

Lexical Decision Task : The lexical decision task (LDT) is a procedure used in many psychology and psycholinguistics experiments. The basic procedure involves measuring how quickly people classify stimuli as words or non-words; the participant needs to decide about whether combinations of letters are words or non-words. As an example, “GIRL” is a real word, the response should be “yes, this is a real word”, but the letters “XLFFE” would have the correct response of “No, this is not a real word”.
