The lesson demonstrates the effect of learning and physiological processes on reaction times to an auditory stimulus.
Students hear two presentation schedules of clicks through a set of headphones. The Subject presses a pushbutton hand switch as quickly as possible after hearing the click.
Students can then perform a statistical analysis of the results including: group mean, variance and standard deviation.
Observe the effects of learning and physiological processes on reaction times.
Compare reaction times with two presentation schedules: fixed intervals and random intervals.
Calculate statistics of group mean, variance, and standard deviation.
Tasks Performed by the Student
BSL Lessons are designed to allow at least four students to record and save data in a normal lab period (60-90 minutes). Typically, labs work most efficiently with three or more students working together at each BSL station.
React to a schedule of fixed interval clicks.
React to a schedule of random clicks.
Add active learning segments designed by students or instructor to expand this lesson.
Very easy to setup and record the data.
Automatically calculates the reaction time.
Guides the student through the statistical analysis of a data set.
The software automates the setup procedure for the student. There are no knobs and dials to confuse them.
On-screen commands prompt the students throughout the lesson.
BIOPAC’s Simple Sensors warn students if they plug the wrong device or transducer into the system.
The lesson will also work with different stimuli (see Lesson 11A for visual stimulus with OUT4).
The lesson will also work as part of a group study.
BSL Instructor’s Guide provides lab tips and lesson options.
BSL Answer Guide included.

How do physiological signals change when we experience stress? How can we monitor those changes continuously so we can aim to improve our quality of life? BIOPAC will present a wide array of noninvasive and continuous measurements of stress-related physiological signals and provide in-depth guidance about best practices for recording and data analysis.
You Will Learn How To: • Select the right measurements and obtain good data • Choose which signals to record-including fNIRS, ECG, EDA, Respiration, Blood pressure, etc. • Recognize the importance of each signal in the context of the stress response • Analyze the respective signals with live examples • Take measures best suited for short-term vs. long-term recording
BIOPAC offers complete systems for life science research and education—human, animal, or in vivo studies, as well as powerful software and automated analysis including industry-standard data acquisition amplifiers, transducers & electrodes. BIOPAC can be used inside or outside the lab to measure physiology anytime, anyplace.
