POLYGRAPHY ( CRI 328/L)
PRACTICAL LABORATORY ACTIVITY
Actual attachment and interpretation of the polygraph tracing
TASK ASSESSMENT:
Students shall be given ten (1:45) HOURS to attach the major components of the polygraph instrument to the subject and define and discuss
the functions and the use of every component. Skillfully interpret the result of the polygraph chart tracing
OBJECTIVE: Apply knowledge and skills learned on previous familiarization on the actual attachment of major components and functions of
the transducers
