The lesson demonstrates the effect of learning and physiological processes on reaction times. 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.
EXPERIMENTAL OBJECTIVES
Observe the effects of learning and physiological processes on reaction times.
Compare reaction times with two presentation schedules: fixed intervals and pseudo-random intervals.
Calculate statistics of group mean, variance, and standard deviation.
TASKS PERFORMED BY THE STUDENT
React to a schedule of fixed interval clicks.
React to a schedule of pseudo-random clicks.
KEY FEATURES
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.
The lesson will also work as part of a group study.
