How can increased heart rate indicate stress or deception?

• It is a sign of physical fitness.

• It can be a physiological response to stress or anxiety, often associated with deception.

• It indicates a person's level of intelligence.

• It shows that a person is relaxed and calm.

What is a polygraph test used for?

• To measure physiological responses to determine truthfulness.

• To assess cognitive abilities and intelligence.

• To evaluate emotional stability and mental health.

• To analyze handwriting and detect forgery.

What physiological responses might a person experience when telling a lie?

• Increased heart rate, increased respiration rate, sweating.

• Decreased heart rate, increased appetite, calmness.

• Stable heart rate, decreased respiration rate, relaxation.

• Increased heart rate, decreased respiration rate, fatigue.

What are the body's reactions that can be felt, detected, or measured called?

• Physiological responses.

• Emotional reactions.

• Cognitive processes.

• Behavioral changes.

What type of data is taken during a polygraph test to provide a reference point for physiological responses?

• Baseline data

• Control data

• Reference data

• Sample data

What is the significance of replicating experiments in scientific research?

• It helps to verify results and ensure reliability and validity of findings.

• It allows researchers to publish more papers.

• It reduces the time needed for research.

• It eliminates the need for peer review.

What does 'baseline' refer to in experimental design?

• The final set of data collected after the experiment is complete.

• The initial set of data collected before any experimental manipulation.

• A control group that receives no treatment during the experiment.

• The average of all data points collected during the experiment.

Why is it important to have a control group in an experiment?

• A control group provides a standard for comparison, helping to isolate the effects of the independent variable.

• A control group is used to manipulate the independent variable directly.

• A control group ensures that all variables are kept constant throughout the experiment.

• A control group is necessary to increase the sample size of the experiment.

What is a physiological response?

• A reaction that can be measured, such as heart rate or sweating.

• An emotional reaction to a stimulus.

• A cognitive process that involves thinking and reasoning.

• A social behavior exhibited in group settings.

What is the purpose of control questions in a polygraph test?

• To establish a baseline for comparison with relevant questions.

• To confuse the subject during the test.

• To determine the subject's emotional state.

• To increase the accuracy of the test results.
