Using LabTutor, students can explore methods in psychophysiology and experimental psychology. They can analyze methods such as biofeedback, classical conditioning, electrodermal response, perception, reaction time, and psychological bias.
Set-up experiments easily with simple diagrams and videos
Measure blood pressure, pulse rate and skin temperature while participants perform the Stroop test
Witness heart rate changes in response to induced emotional stress
Put classical conditioning theory into practice with an analysis of skin conductance

Investigate conscious and unconscious control of biofeedback mechanisms. Manipulate a participant’s emotional state in order to alter skin temperature, heart rate and the electrodermal response. Use biofeedback to determine if conscious control is more or less effective.
Learn how to measure skin conductance. Understand how conductance, respiratory rate, heart rate and skin temperature change in response to stress. Use this information to complete a polygraph (lie detection test) and correctly interpret the results.
Record EMG during voluntary muscle contractions and investigate how contractile force changes with increasing demand. Examine the activity of antagonist muscles, see the phenomenon of coactivation and calculate nerve conduction velocity.
Record electrical activity associated with eye movements and recognize common artifacts in EOG recordings. Measure and understand the significance of angular displacement measurements and smooth tracking, and investigate aspects of gaze holding.
Become familiar with the basic psychophysiological measurements of skin conductance, respiratory rate, blood pressure, and electromyography. Combine these skills in the performance of a simple psychophysiology experiment.
Find the blind spot, test for color blindness and explore the science behind some optical illusions. Determine the distribution of touch and taste receptors, and investigate thermoception. Assess joint position sense and the perception of balance.
Recognize artifacts in an EEG signal caused by blinking and subject movement. Record and identify alpha and beta EEG rhythm, and analyze how a signal is affected by opening and shutting the eyes, mental activity and auditory stimulation.
Discover the responses of reflexes and reaction times to a variety of stimuli. Elicit and quantify a knee jerk reaction, trigger the pupillary light reflex and a withdrawal reflex, and measure reaction time in response to a visual cue under varying conditions.
