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
- EDA: Electrodermal Activity
- EEG: Electroencephalography
- EMG: Electromyography
- ECG: Electrocardiogram
- EOG: Electro-oculogram
- Heart Rate
- Eye Tracking
Various Event Related Studies can be performed using iWorx Equipment.
Also known as skin conductance response (SCR), skin conductance Level (SCL) and galvanic skin response, GSR).
EDA can be measured using the following:
EEG can be measured using the following:
EMG can be measured using the following:
ECG can be measured using the following:
EOG can be measured using the following:
Temperature can be measured with:
Heart Rate can be measured using the following:
Respiration can be measured using the following:
iWorx Psychological Physiology Solutions provide everything you need to perform professionally developed experiments and exercises demonstrating essential concepts in psychological physiology.
The IX-B3G recording module allows recording of up to three channels of ECG, EMG or EEG as well as GSR (galvanic skin response).
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.
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.
The IX-B3G recording module allows recording of one channel of GSR (galvanic skin response).
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”.
